His comments come as Russian forces continue their offensive in the Donbas region. The Donbas refers to the two eastern Ukrainian regions of Luhansk and Donetsk — a major strategic, political and economic target for the Kremlin.

Speaking at his general audience to thousands of people in St. Peter’s Square, he said the block should be lifted because many millions of people depend on wheat from Ukraine, particularly in the world’s poorest countries.

Speaking to the RIA Novosti news agency, Ryabkov said of U.S. foreign policy that “the remnants of a responsible, sound approach to the situation have simply been scrapped.”

OPEC and non-OPEC countries are scheduled to discuss the next phase of production policy on Thursday.

Speaking in an evening address to the nation, Zelenskyy said the cities of Sievierodonetsk, Lysychansk, and Kurakhove are now at the epicenter of the confrontation.“Given the presence of large-scale chemical production in Sievierodonetsk, the Russian army’s strikes there, including blind air bombing, are insanity,” he said.“But on the 97th day of such a war, it is no longer surprising that for the Russian military, for Russian commanders, for Russian soldiers, any madness is absolutely acceptable.”

On average, more than 2 children are killed and more than 4 are injured every day in Ukraine due mostly to attacks using explosive weapons in populated areas, according to reports verified by the Office of the United Nations High Commissioner for Human Rights.Civilian infrastructure critical for children, including 256 health facilities and hundreds of schools, have also been damaged or destroyed in the war.

U.S. officials have been hesitant to send MLRS to Ukraine over concerns that Russia may view it as an escal

Moscow, which in 2016 banned the Mejlis, a body representing Crimean Tatars, rejected the report's findings. It says a March 2014 referendum legitimised its "incorporation" of Crimea.The Crimea battalion performed reconnaissance against Russian forces around Yasnohorodka, a village 25km west of Kyiv, and later in nearby Motyzhyn, Akayev said."The residents here were initially very scared when they saw us because they didn't know who we were. We had to shout 'we are Ukrainian'... then people started slowly coming out of their homes and they gave us tea."

"We wanted to buy this place, to build a Crimean Tatar school and a mosque here... It didn’t come to anything, and then this happened," Akayev said, gesturing at the building’s charred remains which he said was the result of Russian shelling."I (still) dream about this project, but really I just want to return home to Crimea."

“As a venture-backed scale-up that will need to fundraise again in the future, we therefore need to adjust our business plan to reduce costs and accelerate our path to profitability.”

The recent raft of layoffs in the industry highlights a broader shift in investor sentiment toward high-growth tech companies, many of which have taken steps to cut down on costs recently against the backdrop of a sharp plunge in global stock markets. Earlier this week, buy now, pay later firm Klarna said it would lay off about 10% of staff following reports the company was seeking a new round of funding that would reduce its valuation by a third.

Meanwhile, New York start-ups Fridge No More and Buyk — which both raised money from Russian investors — wound down their operations after facing issues with fundraising after Russia’s invasion of Ukraine.

Earlier this month, London-based grocery service Jiffy said it would stop making deliveries and instead shift its focus toward in-person grocery collection, in a bid to convince investors that it can achieve profitability. The company has since announced plans to resume deliveries through a deal with Zapp.

“It’s a historic, big deal,” said Robert McNally, an energy adviser to President George W. Bush. “This will reshape not only commercial relationships but political and geopolitical ones as well.”E.U. officials have yet to release all the details of their effort to squelch Russian oil exports but have said those policies will go into effect over months. That is meant to give Europeans time to prepare, but it will also give Russia and its partners time to devise workarounds. Who will adapt

In addition, Germany and Poland have pledged to stop importing oil from Russia by pipeline, which means Europeans could reduce Russian imports by 3.3 million barrels a day by the end of the year.And the union has said European companies will no longer be allowed to insure tankers carrying Russian oil anywhere. That ban will also be phased in over several months. Because many of the world’s largest insurers are based in Europe, that move could significantly raise the cost of shipping Russian energy, though insurers in China, India and Russia itself might now pick up some of that business.Before the invasion of Ukraine, roughly half of Russia’s oil exports went to Europe, representing $10 billion in transactions a month. Sales of Russian oil to E.U. members have declined somewhat in the last few months, and those to the United States and Britain have been eliminated.

Another hope of Western leaders is that their moves will reduce Russia’s position in the global energy industry. The idea is that despite its efforts to find new buyers in China, India and elsewhere, Russia will export less oil overall. As a result, Russian producers will need to shut wells, which they will not be able to easily restart because of the difficulties of drilling and producing oil in inhospitable Arctic fields.

“Why wait six months?” asked David Goldwyn, a top State Department energy official in the Obama administration. “As the sanctions are configured now, all that will happen is you will see more Russian crude and product flow to other destinations,” he said. But he added, “It’s a necessary first step.”

Russian natural gas for some time, possibly years. That could preserve some of Mr. Putin’s leverage, especially if gas demand spikes during a cold winter. European leaders have fewer alternatives to Russian gas because the world’s other major suppliers of that fuel — the United States, Australia and Qatar — can’t quickly expand exports substantially.Russia also has other cards to play, which could undermine the effectiveness of the European embargo.

India is getting about 600,000 barrels a day from Russia, up from 90,000 a day last year, when Russia was a relatively minor supplier. It is now India’s second-biggest supplier after Iraq.But India could find it difficult to keep buying from Russia if the European Union’s restrictions on European companies insuring Russian oil shipments raise costs too much.“India is a winner,” said Helima Croft, RBC’s head of commodity strategy, “as long as they are not hit with secondary sanctions.”

In 1453, Mehmed II the Conqueror led the Ottoman Turks in seizing the ancient city of Constantinople, the Byzantine Empire’s capital. This put an end to 1,000-year reign of the Byzantine Empire.

Sultan Mehmed renamed the city Istanbul, meaning “the city of Islam” and made it the new capital of the Ottoman Empire.

By 1517, Bayezid’s son, Selim I, brought Syria, Arabia, Palestine, and Egypt under Ottoman control.

The Ottoman Empire reached its peak between 1520 and 1566, during the reign of Suleiman the Magnificent

The Ottomans were known for their achievements in art, science and medicine.

Some of the most popular forms of art included calligraphy, painting, poetry, textiles and carpet weaving, ceramics and music.

The Ottomans learned and practiced advanced mathematics, astronomy, philosophy, physics, geography and chemistry.

Under Sultan Selim, a new policy emerged, which included fratricide, or the murder of brothers.

The threat of assassination was always a concern for a Sultan. He relocated every night as a safety measure.

the millet system, a community structure that gave minority groups a limited amount of power to control their own affairs while still under Ottoman rule.

The devshirme system lasted until the end of the 17th century.

Starting in the 1600s, the Ottoman Empire began to lose its economic and military dominance to Europe.

n 1878, the Congress of Berlin declared the independence of Romania, Serbia and Bulgaria.During the Balkan Wars, which took place in 1912 and 1913, the Ottoman Empire lost nearly all their territories in Europe.

At the start of World War I, the Ottoman Empire was already in decline. The Ottoman Turks entered the war in 1914 on the side of the Central Powers (including Germany and Austria-Hungary) and were defeated in 1918.

In 1915, Turkish leaders made a plan to massacre Armenians living the Ottoman Empire. Most scholars believe that about 1.5 million Armenians were killed.

After ruling for more than 600 years, the Ottoman Turks are often remembered for their powerful military, ethnic diversity, artistic ventures, religious tolerance and architectural marvels.

The mighty empire’s influence is still very much alive in the present-day Turkish Republic, a modern, mostly secular nation thought of by many scholars as a continuation of the Ottoman Empire.

Europe faces the prospect of Russia throttling the flow of piped gas. Even in the absence of a cut-off, it was expected to spend $1trn on energy in 2022, twice as much as in 2019.

Russia would also suffer heavy sanctions. Its banks would be harshly penalised and its economy deprived of crucial American high-tech components.

Perhaps, then, he will start with a less ambitious invasion. However, a limited war could claim many lives and be hard to contain.

Perhaps Mr Putin is planning a full-scale invasion, with Russian forces thrusting deep into Ukraine to seize the capital, Kyiv, and overthrow the government. Or he may seek to annex more territory in eastern Ukraine, carving out a corridor linking Russia with Crimea, the Ukrainian peninsula Mr Putin grabbed in 2014. Then again, he may want a small war, in which Russia “saves” Kremlin-backed separatists in Donbas, an eastern region of Ukraine, from supposed Ukrainian atrocities—and, at the same time, degrades Ukraine’s armed forces.

The global order has long been buttressed by the norm that countries do not redraw other countries’ borders by force of arms. When Iraq seized Kuwait in 1990 an international coalition led by America kicked it out.

if he seizes a bigger slice of Ukraine, it is hard to see him suddenly concluding that the time has come to make peace with NATO.

More likely, he would push on, helped by the newly established presence of Russian troops in Belarus to probe NATO’s collective-security pact, under which an attack on one member is an attack on all.

Not only would he relish the chance to hollow out America’s commitments to Europe, but he has also come to rely on demonising an enemy abroad to justify his harsh rule at home.

Meanwhile, diplomats should keep talking, looking for common ground on, say, arms control and pressing for a face-saving climbdown that Mr Putin and his captive media would be free to spin however they wish.

The plan includes production of a graphic propaganda video that would show staged explosions and would use corpses and actors depicting grieving mourners, according to the official, who was not authorized to comment and spoke on the condition of anonymity.The plan, which was revealed in declassified intelligence shared with Ukrainian officials and European allies in recent days, is the latest allegation by the U.S. and Britain that Russia is plotting to use a false pretext to go to war against Ukraine.

He reiterated Turkey’s commitment to Ukraine’s territorial integrity and sovereignty.

Meanwhile, Putin met with Argentinian President Alberto Fernandez in Moscow and then spoke by phone to Macron, who had a call Wednesday night with U.S. President Joe Biden. Macron then spoke with Zelenskyy.

The NATO chief said Russian forces in Belarus are likely to rise to 30,000, including special forces, supported by fighter jets and missiles.

French Foreign Minister Jean-Yves Le Drian confirmed Thursday that Paris is sending troop reinforcements to Romania under NATO command, as part of France’s commitment to the alliance and its member states in Eastern Europe.

He did not say how many French soldiers will be deployed. The announcement came a day after the U.S. said it was moving troops stationed in Germany to Romania.

Ukraine’s defense minister is urging calm, saying the likelihood of a Russian invasion was “low.”Oleksii Reznikov said the threat of attack has loomed over the country since 2014, the year Russia seized Crimea, but he added: “There are no grounds for panic, fear, flight or packing of bags.”The minister said there are about 115,000 Russian troops near Ukraine’s border, including those deployed to Belarus for war games, but he said no battle groups have been detected along Ukraine’s border with Belarus. He also reiterated earlier assurances that Kyiv doesn’t plan to attack rebel-held areas in the war-torn east of Ukraine or Crimea — something the Kremlin has accused Kyiv of plotting.

An ice hockey fan, Putin will also attend Friday’s opening ceremony of the Winter Olympics.His talks with Chinese President Xi Jinping on Friday will be their first face-to-face since 2019 and will help cement a strong personal relationship that has been a key factor behind a growing partnership between the two former Communist rivals.

it is palpable: what happens in the UK and Europe doesn’t stay in the UK and Europe.

In the past couple of weeks, the UK and several countries in Europe, including Germany, France and Switzerland, are experiencing a new wave.

This is the sixth warning from the UK and Europe to the United States.

Wastewater surveillance is relatively sparse in the United States, but 15% of the 410 sites where it was conducted between 24 February to 10 March 2022 showed a greater than 1000% increase compared with the prior 15-day period

Now we are at a point with very low vaccination and booster rates, only 64% of the populations has had two shots, and 29% three shots. That puts the United States at 65th and 70th in the world ranking of countries, respectively.

Rather than focusing on what precisely is driving the new wave, the imperative is to drive some preventive action.

As with the first five warnings from the UK and Europe, the United States did not take heed. Instead of proactively gearing up with non-pharmaceutical interventions (masks, quality of masks, distancing, air filtration, ventilation, aggressive testing, etc.), it just reacted to the surges when they were manifest.

the BA.2 variant is gaining steam in the United States and is now accounting for more than 30% of new cases.

Not only is there a gaping hole in our immunity wall, but the $58bn budget of the American Pandemic Prepared Plan (AP3) advanced by the White House to comprehensively address the deficiencies was gutted by the Senate, reduced to $2bn, now threatening to cancel the order of more than 9.2m Paxlovid pills, the Test-to Treat program announced at the State of the Union address, along with better data, wastewater surveillance, efforts to develop a pan-coronavirus vaccine, research on long Covid, and many other critical public health measures.

We haven’t even seen a new, major variant yet, but there are too many reasons to believe that is likely in the months ahead, owing to extensive animal reservoirs and documented cases of spillover to humans, a large number of immunocompromised people in whom the virus can undergo accelerated evolution, rare but increasingly seen co-infections, and lack of containment of the virus globally.

Unfortunately, we have a mindset that the pandemic is over, which couldn’t be further than the truth

dd to all this is what is happening in China, which has fully relied on a zero-Covid policy, resulting in very little natural immunity, and vaccines that have weak efficacy against Omicron

The exhibition is one of several ways that Ukraine’s government is highlighting the devastation its people have endured even as new suffering is inflicted every day.

And Ukraine has taken the rare step of prosecuting Russian soldiers for war crimes just months after they were allegedly committed, greatly accelerating the normal judicial timetable.

“It is necessary to explain to our children what is happening in Ukraine now,” Mr. Spodinskiy said, as other visitors took photographs of the debris. “We cannot speak with our children as if nothing is happening,” he added, “because they clearly understand everything, and they see what happens in our country.”

“The history of our country is being created, and now this is an opportunity to get in touch with it,” said another visitor, Serhiy Pashchukov, a 31-year-old from Luhansk, which was occupied by Russia in 2014.

The sign, and everything else in the basement, was taken from a bomb shelter in a Kyiv suburb, Hostomel, the site of an airport that Russian soldiers tried to take in the first days of the war.

The rooms are dank and cold, but the most striking thing, many visitors said, was that it smells as if the people who sheltered with their belongings there — including onions, blankets, and toys — had just left.

“We had a similar basement in Bucha in a newly built apartment building,” said Evgeniya Skrypnyk, a 32-year-old from a suburb of Kyiv where Russian soldiers killed and terrorized civilians.

The one historical inaccuracy in the shelter was the absence of the five buckets that stood in the hallway where the people who lived underground for more than a month relieved themselves.

Remembrance of World War II has become more complex since the war started. In Russia, the Kremlin has sought to glorify the Soviet victory — to which millions of Ukrainians contributed — as a source of national pride. But it has also called upon memories of that war to justify and build support for the invasion of Ukraine, with Mr. Putin seeking to falsely portray Ukrainian leaders as “Nazis.”

Mr. Savchuk said that in light of the current war, people were talking about a “complete reconstruction” of the museum complex, whose architecture is intended to awe visitors with the memory of the Soviet victory in World War II, to de-emphasize the fight against Nazi Germany.

“This war changed everything,” he said. “A museum is not only an exhibition, it is a territory, it is its monuments, it is a place of memory. We are thinking about changing not only the ideology, but also the architecture, the emphasis.”

The West has used export bans to cut off technology shipments, leaving Moscow struggling to replace and repair its arms.

“It is an attempt also to show to the Turkish public at home and to Turks living in Germany and other Western European countries that Erdogan has the power to assert his will beyond the political boundaries of the country,” said Mustafa Aksakal, a professor of history at Georgetown University in Washington. “The name change may seem silly to some but it puts Erdogan in the role of protector, of safeguarding international respect for the country.”

Mr. Erdogan’s dislike of the Anglicized name was on display in December 2019, when he unveiled prototypes of a locally made electric car. He signaled that products should say they were “Made in Türkiye,” not “Made in Turkey.”

When the turkey started making its way to other parts of the world in the 16th century, people tried to associate it with known places, Mr. Aksakal said. For instance, he said, it is known as the Indian bird in both French and Turkish.

The system is designed to help students get along with one another, said Dee Mostofi, a Stanford spokeswoman. “The process aims to promote a climate of respect, helping build understanding that much speech is protected while also offering resources and support to students who believe they have experienced harm based on a protected identity,” she said.

The Stanford faculty’s effort is part of broader pushback against bias-reporting systems around the country. About half of college campuses have one—more than twice as many as five years ago—according to a 2022 survey by Speech First, a conservative nonprofit.

Prof. Santiago said he is wary that anonymous complaints could be exaggerated or used to attack someone. He helped collect 77 faculty signatures to petition the school to investigate free speech and academic freedom on campus, the first step to getting rid of the anonymous-reporting system. 

The system defaults to anonymous reporting and most students file that way. They use an online form to describe how the bias was demonstrated, which triggers an inquiry within 48 hours. Both parties are contacted.

Participation in the inquiry is voluntary. But it may not feel that way to accused students, said Juan Santiago, a professor of mechanical engineering who favors getting rid of the system.

“If you’re an 18-year-old freshman and you get contacted by an administrator and told you’ve been accused of some transgression, what are you going to do?” Prof. Santiago said. “They may not call that punitive but that can be very stressful.”

At Stanford, students can report a “Protected Identity Harm Incident,” which is defined as conduct targeting an individual or group on the basis of characteristics including race or sexual orientation. The system is meant to “build and maintain a better, safer, and more respectful campus community,” according to the school’s website.

Senior Christian Sanchez, executive vice president of the Associated Students of Stanford University, the student-government group, said the system is necessary and important. Mr. Sanchez, who describes himself as Chicano, said he has bristled in the past when another student has addressed him as “G,” short for gangster.

He has let it roll off his back, he said, but less thick-skinned students should have a path for redress.

he reports are stored in a platform operated by a third party called Maxient, a Charlottesville, Va.-based company that has contracts with 1,300 schools—mostly colleges and universities in the U.S

Only Maxient and a small number of people within the student affairs office have access to the records, said Ms. Mostofi. She declined to say how long they are stored.

A dashboard maintained by the school lists a few incidents students have reported using the anonymous system, including the removal of an Israeli flag and a racial slur written on a whiteboard hanging on a dorm-room door.

At the University of California, which includes 10 campuses, the reporting system collected 457 acts of “intolerance or hate” during the 2021-22 school year. Of those, 296 were defined as offensive speech. The UC said those incidents include “gestures, taunts, mockery, unwanted jokes or teasing, and derogatory or disparaging comments of a biased nature.”

Free-speech advocacy organizations including the Goldwater Institute, the Foundation for Individual Rights and Expression and Alumni Free Speech Alliance have advocated against bias-reporting mechanisms.

After Speech First challenged bias-response systems at the University of Texas, the University of Michigan and the University of Central Florida, all three schools changed or disbanded their systems.

Stanford Business School professor Ivan Marinovic said the bias-reporting system reminded him of the way citizens were encouraged to inform on one another by governments in the Soviet Union, East Germany and China. 

“It ignores the whole history,” he said. “You’re basically going to be reporting people who you find offensive, right? According to your own ideology.”

They coexisted in Europe for thousands of years, apparently trading tools and sharing cultures. Some groups survived the Ice Age, while others vanished,

when farmers arrived in Europe about 8,000 years ago, they encountered the descendants of this long history, with light-skinned, dark-eyed people to the east, and possibly dark-skinned and blue-eyed people to the west.

“We lack still an understanding of why these movements were triggered. What happened here, why it happened — it’s strange.”

Modern humans arose in Africa and expanded to other continents about 60,000 years ago

These early Europeans have almost no genetic link to younger remains of hunter-gatherers. It appears that the first modern humans in Europe may have disappeared along with the Neanderthals

he oldest DNA of modern humans in Europe, dating back 45,000 years, undermines such a simple story. It comes from people who belonged to a lost branch of the human family tree. Their ancestors were part of the expansion out of Africa, but they split off on their own before the ancestors of living Europeans and Asians split apart.

About 33,000 years ago, as the climate turned cold, a new culture called the Gravettian arose across Europe. Gravettian hunters made spears to kill woolly mammoths and other big game. They also made so-called Venus figurines that might have represented fertility.

When the glaciers retreated, some descendants of the Fournol continued living in Iberia. But others expanded north as a new population, which Dr. Posth and his colleagues called GoyetQ2. “It really seems like a peopling of Europe after the last glacial maximum,

Dr. Posth and his colleagues found DNA in Gravettian remains scattered across Europe. The scientists had expected all of the individuals to have come from the same genetic population, but instead found two distinct groups: one in France and Spain, and another in Italy, the Czech Republic and Germany.

“They were very distinct, and this was a very big surprise to us because they practiced the same archaeological culture,”

Dr. Posth and his colleagues named the western population the Fournol people, and found a genetic link between this group and 35,000-year-old Aurignacian remains in Belgium.

They called the eastern group Vestonice, and discovered that they share an ancestry with 34,000-year-old hunter-gatherers who lived in Russia.

That genetic gulf led Dr. Posth and his colleagues to argue that the Fournol and Vestonice belonged to two waves that migrated into Europe separately. After they arrived, they lived for several thousand years sharing the Gravettian culture but remaining genetically distinct.

It’s clear from the new study that they were not isolated entirely from each other. In Belgium, the scientists found 30,000-year-old remains with a mix of Fournol and Vestonice ancestry.

About 26,000 years ago, the two groups faced a new threat to their survival: an advancing wall of glaciers. During the Ice Age, from 26,000 to 19,000 years ago, European hunter-gatherers were shut out of much of the continent, surviving only in southern refuges.

the refuge of the Iberian Peninsula, the region now occupied by Spain and Portugal, by studying DNA in the teeth of a 23,000-year-old man found in a cave in southern Spain. His DNA revealed that he belonged to the Fournol people who lived in Iberia before the Ice Age. The researchers also found genetic markers linking him to a 45,000-year-old skeleton discovered in Bulgaria.

When these groups arrived in Europe, Neanderthals had already been living across the continent for more than 100,000 years. The Neanderthals disappeared about 40,000 years ago, perhaps because modern humans outcompeted them with superior tools.

The Vestonice, by contrast, did not survive the Ice Age. When the glaciers were at their most expansive, the Vestonice may have endured for a time in Italy. But Dr. Posth and his colleagues found no Vestonice ancestry in Europeans after the Ice Age. Instead, they discovered a population of hunter-gatherers that appeared to have expanded from the Balkans, known as the Villabruna. They moved into Italy and replaced the Vestonice.

For several thousand years, the Villabruna were limited to southern Europe. Then, 14,000 years ago, they crossed the Alps and encountered the GoyetQ2 people to the north. A new population emerged, its ancestry three parts Villabruna to one part GoyetQ2.

This new people, which Dr. Posth and his colleagues called Oberkassel, expanded across much of Europe, replacing the old GoyetQ2 population.

another climate shift could explain this new wave. About 14,000 years ago, a pulse of strong warming produced forests across much of Europe. The Oberkassel people may have been better at hunting in forests, whereas the GoyetQ2 retreated with the shrinking steppes.

To the east, the Oberkassel ran into a new group of hunter-gatherers, who probably arrived from Russia. The scientists named this group’s descendants, who lived in Ukraine and surrounding regions, the Sidelkino.

in Iberia, there were no great sweeps of newcomers replacing older peoples. The Iberians after the Ice Age still carried a great deal of ancestry from the Fournol people who had arrived there thousands of years before the glaciers advanced. The Villabruna people moved into northern Spain, but added their DNA to the mix rather than replacing those who were there before.

When the first farmers arrived in Europe from Turkey about 8,000 years ago, three large groups of hunter-gatherers thrived across Europe: the Iberians, the Oberkassel and the Sidelkino. Living Europeans carry some of their gene

The Sidelkino people in the east had genes associated with dark eyes and light skin. The Oberkassel in the west, in contrast, probably had blue eyes and may have had dark skin

These three groups of hunter-gatherers remained isolated from each other for about 6,000 years, until the farmers from Turkey arrived. After this advent of agriculture, the three groups began mixing, the scientists found. It’s possible that the spread of farmland forced them to move to the margins of Europe to survive. But over time, they were absorbed into the agricultural communities that surrounded them.

every continent will likely have its own history of hunter-gatherer migrations.

it is now possible to extract human DNA from cave sediments rather than searching for bones and teeth.

A handful of financial institutions produced them when Rio de Janeiro hosted in 2016, using a mixture of macroeconomic indicators and performances at previous Olympics to forecast total medal hauls for each country.

Gracenote’s distinguishing feature is the ability to produce quantitative analysis for each event.

Gracenote still uses the old system to produce its public medal table, which also deals in absolute forecasts, rather than fractional ones. If a French athlete, say, is the most likely to win an event, France gets awarded one gold medal in the table, even though the true probability of the athlete winning gold is less than 100% and his chances of claiming silver and bronze are greater than 0%.

the Elo rating system, which was developed for chess by Arpad Elo, a Hungarian physicist. The formula exchanges ranking points from the loser to the winner, with greater rewards for beating stronger opponents. The difference in ratings points between two rivals can be easily used to calculate the probability that one will beat the other.

Yet only two events on the winter Olympics programme, curling and ice hockey, involve head-to-head contests.

Those that compete in teams have their scores blended with their compatriots. And for those that participate in a number of events, such as Ms Dahlmeier, results in related disciplines affect multiple ratings. A strong performance in the biathlon sprint, a group race, would boost her ranking in the pursuit, a staggered race, for example.

The best way to answer that question is to take every previous contest in the sport and analyse how past results correlate with future success.

The bans have benefited Norway most, as the country will likely gain of the five of the 12 foregone medals—enough to nudge it ahead of Germany into first place in terms of total medals won.

Mr Gleave notes that the favourite only wins about 30% of the time, a lower share than in any other winter sport. Ms Dahlmeier’s rating has dwindled a little, but not by enough to suggest that last year’s record breaker has become this year’s flop.

Gracenote’s research into age curves for each sport shows that the best biathletes can maintain their peak performance into their early 30s (see chart). Expect to see more event-by-event forecasting at future Olympics, too.

economic output must flow either to owners of capital, in the form of profits, dividends and rents, or to labour, as wages, salaries and perks. Economists refer to this as the “capital” or “labour” share of GDP. Who has the upper hand in the post-lockdown economy?

First we calculate a high-frequency measure of the capital-labour share across 30 mostly rich countries.

In 2020 the aggregate labour share across this group soared (see chart 1). This was largely because firms continued to pay people’s wages—helped, in large part, by government-stimulus programmes—even as GDP collapsed. Advantage, labour.

More recently, however, the battle seems to have shifted in favour of capital.

most economists anyway argue that labour’s share is not a perfect gauge of economic fairness, since it is so hard to measure.

In the first camp is Britain. There, underlying wage growth is in the region of 5% a year, unusually fast by rich-world standards.

But corporations seem not to have much pricing power, meaning that they are struggling to fully offset higher costs in the form of higher prices.

Labour seems to be winning out at the expense of capital.

The second group consists of most other rich countries outside America.

There, neither labour nor capital seems able to triumph. After correcting for pandemic-related distortions Japan’s pay growth appears to be slowing to below 1% a year

Pay settlements in Italy and Spain are treading water, while wage growth in Australia, France and Germany remains well below where it was before the pandemic. Workers in these places are not really joining in with the inflationary party.

In Europe pre-tax profit margins, as measured in the national accounts, have risen in recent months but remain below where they were just before the pandemic.

In Japan the “recurring” profits before tax of large and medium-sized firms recently returned to pre-pandemic levels. The profits of smaller firms remain well below, however.

A series of unusually large stimulus payments may mean that households are able to absorb the higher prices that companies impose.

Wages are rising, but nonetheless markups are responsible for more than 70% of inflation since late 2019,

In a recent report, analysts at Bank of America argue that greater pricing power helps explain why American equities have a higher price-earnings ratio than European ones.

Some economists wonder if workers will before long demand even higher wages to compensate for higher shop prices.

He wants to undermine America, to shrink American influence, to remove the power of the democracy rhetoric that so many people in his part of the world still associate with America. He wants America itself to fail.

of all the questions that repeatedly arise about a possible Russian invasion of Ukraine, the one that gets the least satisfactory answers is this one: Why?

Why would Russia’s president, Vladimir Putin, attack a neighboring country that has not provoked him? Why would he risk the blood of his own soldiers?

To explain why requires some history

the most significant influence on Putin’s worldview has nothing to do with either his KGB training or his desire to rebuild the U.S.S.R. Putin and the people around him have been far more profoundly shaped, rather, by their path to power.

Putin missed that moment of exhilaration. Instead, he was posted to the KGB office in Dresden, East Germany, where he endured the fall of the Berlin Wall in 1989 as a personal tragedy.

Putin, like his role model Yuri Andropov, who was the Soviet ambassador to Hungary during the 1956 revolution there, concluded from that period that spontaneity is dangerous. Protest is dangerous. Talk of democracy and political change is dangerous. To keep them from spreading, Russia’s rulers must maintain careful control over the life of the nation. Markets cannot be genuinely open; elections cannot be unpredictable; dissent must be carefully “managed” through legal pressure, public propaganda, and, if necessary, targeted violence.

Eventually Putin wound up as the top billionaire among all the other billionaires—or at least the one who controls the secret police.

Try to imagine an American president who controlled not only the executive branch—including the FBI, CIA, and NSA—but also Congress and the judiciary; The New York Times, The Wall Street Journal, The Dallas Morning News, and all of the other newspapers; and all major businesses, including Exxon, Apple, Google, and General Motors.

He is strong, of course, because he controls so many levers of Russia’s society and economy

And yet at the same time, Putin’s position is extremely precarious. Despite all of that power and all of that money, despite total control over the information space and total domination of the political space, Putin must know, at some level, that he is an illegitimate leader

He knows that this system works very well for a few rich people, but very badly for everyone else. He knows, in other words, that one day, prodemocracy activists of the kind he saw in Dresden might come for him too.

In his mind, in other words, he wasn’t merely fighting Russian demonstrators; he was fighting the world’s democracies, in league with enemies of the state.

All of which is a roundabout way of explaining the extraordinary significance, to Putin, of Ukraine.

Of course Ukraine matters as a symbol of the lost Soviet empire. Ukraine was the second-most-populous and second-richest Soviet republic, and the one with the deepest cultural links to Russia.

modern, post-Soviet Ukraine also matters because it has tried—struggled, really—to join the world of prosperous Western democracies. Ukraine has staged not one but two prodemocracy, anti-oligarchy, anti-corruption revolutions in the past two decades. The most recent, in 2014, was particularly terrifying for the Kremlin

Putin’s subsequent invasion of Crimea punished Ukrainians for trying to escape from the kleptocratic system that he wanted them to live in—and it showed Putin’s own subjects that they too would pay a high cost for democratic revolution.

they are all a part of the same story: They are the ideological answer to the trauma that Putin and his generation of KGB officers experienced in 1989. Instead of democracy, they promote autocracy; instead of unity, they try constantly to create division; instead of open societies, they promote xenophobia. Instead of letting people hope for something better, they promote nihilism and cynicism.

from the Donbas to France or the Netherlands, where far-right politicians hang around the European Parliament and take Russian money to go on “fact-finding missions” to Crimea. It’s a longer way still to the small American towns where, back in 2016, voters eagerly clicked on pro-Trump Facebook posts written in St. Petersburg

Their average age is 68 years old and they have a lot in common. The collapse of the Soviet Union, which Mr Putin famously described as the greatest geopolitical catastrophe of the 20th century, was the defining episode of their adult lives

Four out of five have a KGB background, with three, including the president himself, coming from the ranks of counterintelligence. It is these hardened men, not polished diplomats like Foreign Minister Sergey Lavrov, who run the country’s foreign policy.

In recent years members of this group have become very vocal. Messrs Patrushev and Naryshkin frequently give lengthy interviews articulating their views on global developments and Russia’s international role.

According to them, the American-led order is in deep crisis thanks to the failure of Western democracy and internal conflicts spurred by the promotion of tolerance, multiculturalism and respect for the rights of minorities. A new multipolar order is taking shape that reflects an unstoppable shift in power to authoritarian regimes that support traditional values.

Given the state of affairs in Western countries, the pair contend, it's only natural that they seek to contain Russia and to install pro-Western regimes in former Soviet republics. The West’s ultimate goal of a colour revolution in Russia itself would lead to the country’s conclusive collapse.

Washington sees unfinished business in Russia’s persistence and success, according to Mr Putin’s entourage. As America’s power wanes, its methods are becoming more aggressive. This is why the West cannot be trusted

The best way to ensure the safety of Russia’s existing political regime and to advance its national interests is to keep America off balance.

Seen this way, Ukraine is the central battleground of the struggle. The stakes could not be higher. Should Moscow allow that country to be fully absorbed into a western sphere of influence, Russia’s endurance as a great power will itself be under threat

The fact that the new elite in Kyiv glorifies the Ukrainian nationalists of the 20th century and thumb their noses at Moscow is a huge personal affront.

Messrs Patrushev, Bortnikov and Naryshkin all find themselves on the US Treasury’s blacklist already, along with many other members of Mr Putin’s inner circle. There is no way back for them to the West’s creature comforts. They are destined to end their lives in Fortress Russia, with their assets and their relatives alongside them.

As for sanctions by sector, including those that President Joe Biden’s team plans to impose should Russia invade Ukraine, these may end up largely strengthening the hard men’s grip on the national economy

Import substitution efforts have generated large flows of budget funds that are controlled by the coterie and their proxies, including through Rostec. The massive state conglomerate is run by a friend of Mr Putin’s from his KGB days in East Germany, Sergey Chemezov

In a similar vein, a ban on food imports from countries that have sanctioned Russia has led to spectacular growth in Russian agribusiness. The sector is overseen by Mr Patrushev’s elder son Dmitry, who is Mr Putin’s agriculture minister.

further sanctions wouldn’t just fail to hurt Mr Putin’s war cabinet, they would secure its members' place as the top beneficiaries of Russia’s deepening economic autarky.

The same logic is true of domestic politics: as the country descends into a near-permanent state of siege, the security services will be the most important pillar of the regime. That further cements the hard men’s grip on the country

Russia’s interests are increasingly becoming conflated with the personal interests of the people at the very top of the system.

Upon his arrival at Rzeszów-Jasionka Airport, Biden will be greeted by Polish President Andrzej Duda and receive a briefing on the humanitarian response to the war. He'll meet with service members from the 82nd Airborne Division in Rzeszów before traveling to Warsaw in the evening.On Saturday, the White House says Biden will hold a bilateral meeting with Duda to discuss how the US and allies are responding to the refugee crisis that has ensued as a result of the war. He'll also deliver remarks before returning to Washington.Biden's travel to Poland comes after meetings on Thursday in Brussels, where he attended a slate of emergency summits, announced new actions -- such as sanctions against hundreds of members of Russia's parliament and a commitment to admit 100,000 refugees fleeing Ukraine -- and conferred with global leaders on how the world will respond if Russia deploys a chemical, biological or nuclear weapon.

Poland, which borders Ukraine to the west, has registered more than 2 million Ukrainian refugees crossing into the country. However, the number of refugees staying in Poland is lower, with many continuing on in their journey to other countries.Earlier this month during Vice President Kamala Harris' trip to Poland, Duda personally asked the vice president to speed up and simplify the procedures allowing Ukrainians with family in the US to come to the country. He also warned Harris that his country's resources were being badly strained by the influx of refugees, even as Poland welcomes them with open arms.The White House says that since February 24, the US has provided more than $123 million to assist countries neighboring Ukraine and the European Union to address the refugee influx, including $48 million in Poland.

Biden brought up that he has visited war zones, saying he understood the plight of refugees."I've been in refugee camps. I've been in war zones for the last 15 years. And it's -- it's devastating," he said.Biden also said the refugee influx is "not something that Poland or Romania or Germany should carry on their own."

The Poland trip also comes two weeks after the US rejected Poland's proposals to facilitate the transfer its MiG-29 fighter jets to Ukraine. The US rejected Poland's proposals over fears that the US and NATO could be perceived as taking an escalatory step, further fomenting conflict between the alliance and Russia -- which adamantly opposes Ukraine's ambitions to join the NATO alliance.Ukrainian President Volodymyr Zelensky has repeatedly requested more aircraft for the invasion, making another appeal to NATO leaders on Thursday.
