Celebrated every March, Women's History Month honors the often-overlooked contributions of women in history, society, and culture. This year's theme — "Women Providing Healing, Promoting Hope"— salutes both the brave frontline workers of the ongoing COVID-19 pandemic and the countless women who have provided healing and hope throughout history.

Elizabeth Blackwell, who made history in 1849 by becoming the first woman to earn a medical degree in America, did not even want to be a doctor. She was happy being a teacher — a more "suitable" career for women in the 19th century. She only decided to pursue medicine after a close friend, who was dying of cancer, said her experience would have been better under the care of a female physician.

In 1857, Blackwell recruited her sister Emily — the third woman to earn a medical degree in America — and a physician friend to establish the New York Infirmary for Indigent Women and Children. The free clinic provided female doctors with much-needed training and experience. She also founded the Women's Medical College of the New York Infirmary — the first four-year all-female medical college. The pioneer continued to advocate for women in medicine till her death in 1910 at age 89. Since 2016, Blackwell's birthday — February 3 — has been designated National Women Physicians Day.

(CNN)Two news stories dominated the headlines this week. The ongoing Russian invasion of Ukraine reached its one month mark. And the Senate hosted confirmation hearings for Judge Ketanji Brown Jackson to join the Supreme Court. It's with the Jackson confirmation hearings that we begin our statistical journey into the news of the week.

If Jackson's ratings hold up through her likely confirmation, she would be the most popular nominee to be confirmed since John Roberts in 2005. Jackson's popularity should only help her in the confirmation process. Read MoreA few years ago, I built a statistical model to help understand why senators vote the way they do on Supreme Court nominees. The model took into account variables such as a nominee's qualifications, the ideology of the nominee and the senator, etc.

A lot of that may have had to do with the fact that he was popular. Thomas had a +33-point net popularity rating among Americans, according to an average of polling taken before he was confirmed.

The meeting in Moscow this week between Chinese leader Xi Jinping and Russian President Vladimir Putin is expected to showcase what they have declared a partnership with “no limits” between their countries. Beneath the surface are economic, political, cultural and historical divisions that undercut the relationship.

Russia seeks to disrupt the international order, including through military action. The International Criminal Court last week issued an arrest warrant against Mr. Putin for war crimes. China, which reached its economic stature through the status quo, seeks changes that further its interests, complicating the binational collaboration,

In many ways, the Chinese and Russian economies are highly complementary. Russia exports natural resources China needs to power its industrial economy. China sells goods that Russian consumers want. On the energy front in particular, Chinese purchases of oil and gas since the invasion of Ukraine have helped Russia weather Western sanctions.

A major reason older people are still at risk is that vaccines can’t entirely compensate for their immune systems. A study recently published in the journal Vaccines showed that for vaccinated adults ages 60 and over, the risk of dying from COVID versus other natural causes jumped from 11 percent to 34 percent within a year of completing their primary shot series

A booster dose brings the risk back down, but other research shows that it wears off too. A booster is a basic precaution, but “not one that everyone is taking,”

Unlike younger people, most of whom fully recover from a bout with COVID, a return to baseline health is less guaranteed for older adults. In one study, 32 percent of adults over 65 were diagnosed with symptoms that lasted well beyond their COVID infection

The long-feared “population bomb” may not go off, according to the authors of a new report that estimates that human numbers will peak lower and sooner than previously forecast.

on current trends the world population will reach a high of 8.8 billion before the middle of the century, then decline rapidly. The peak could come earlier still if governments take progressive steps to raise average incomes and education levels.

The new forecasts are good news for the global environment. Once the demographic bulge is overcome, pressure on nature and the climate should start to ease, along with associated social and political tensions.

The rapid advent of artificial intelligence has set off alarms that the technology used to trick people is advancing far faster than the technology that can identify the tricks. Tech companies, researchers, photo agencies and news organizations are scrambling to catch up, trying to establish standards for content provenance and ownership.

The advancements are already fueling disinformation and being used to stoke political divisions

Last month, some people fell for images showing Pope Francis donning a puffy Balenciaga jacket and an earthquake devastating the Pacific Northwest, even though neither of those events had occurred. The images had been created using Midjourney, a popular image generator.

Google’s employees were shocked when they learned in March that the South Korean consumer electronics giant Samsung was considering replacing Google with Microsoft’s Bing as the default search engine on its devices.

Google’s reaction to the Samsung threat was “panic,” according to internal messages reviewed by The New York Times. An estimated $3 billion in annual revenue was at stake with the Samsung contract. An additional $20 billion is tied to a similar Apple contract that will be up for renewal this year.

A.I. competitors like the new Bing are quickly becoming the most serious threat to Google’s search business in 25 years, and in response, Google is racing to build an all-new search engine powered by the technology. It is also upgrading the existing one with A.I. features, according to internal documents reviewed by The Times.

When civilizations promote parity along one axis, they tend to lapse back toward hierarchy along another. Legal equality may be offset by widening economic rifts, as in Western democracies today; the expansion of the franchise to a larger segment of the male population may be accompanied by the fervent demonization of women or non-natives, as in ancient Athens; movements for justice may prompt reactionary backlash, as in France after the 1789 revolution.

At a time when equality is widely lauded as an uncomplicated good, McMahon’s sweeping if occasionally schematic study provides a thought-provoking reminder of its pitfalls

All too often, equality within a group is premised on the exclusion of those outside it.

Valter Longo, a nutrition-obsessed Italian Ph.D. student, wrestled with a lifelong addiction to longevity.

“For studying aging, Italy is just incredible,

Italy has one of the world’s oldest populations, including multiple pockets of centenarians who tantalize researchers searching for the fountain of youth. “It’s nirvana.”

I’m a big fan of science fiction (see my list of favorites from last week)! So when people start bashing the genre, I tend to leap to its defense

this time, the people doing the bashing are some serious heavyweights themselves — Charles Stross, the celebrated award-winning sci-fi author, and Tyler Austin Harper, a professor who studies science fiction for a living

The two critiques center around the same idea — that rich people have misused sci-fi, taking inspiration from dystopian stories and working to make those dystopias a reality.

In some ways, 2023 may still have been the best year in the history of humanity.

Just about the worst calamity that can befall a human is to lose a child, and historically, almost half of children worldwide died before they reached the age of 15. That share has declined steadily since the 19th century, and the United Nations Population Division projects that in 2023 a record low was reached in global child mortality, with just 3.6 percent of newborns dying by the age of 5.

It still means that about 4.9 million children died this year — but that’s a million fewer than died as recently as 2016.

German democracy is not well. The problem is not just the rise of the AfD, which has become strong enough in some regions to aspire to positions of power or at least to seriously disrupt the process of forming stable governments.

It’s that in many parts of the country, a general sense of discontent has tipped over into disdain. People now reject not just the current government but the whole political system.

it is true that Germans have had to deal with a lot: the war in Ukraine, an energy crisis, inflation and, most recently, the painful fallout from war in Gaza. Even though immigration is rising, we still lack skilled labor — teachers, plumbers, I.T. specialists — and public infrastructure is crumbling. Add in an ambitious government green transition agenda hamstrung by brutal infighting and you get a grim picture. Everything, it seems, is changing — and not for the better.

It’s only now becoming clear how little we understood what the United States experienced during that unforgettable year and how deeply it shaped us

I’ve come to think of our current condition as a kind of long Covid, a social disease that intensified a range of chronic problems and instilled the belief that the institutions we’d been taught to rely on are unworthy of our trust

On a wide range of outcomes, including many that were less visible at the time, this country fared much worse during the Covid pandemic than comparable nations did. Distrust, division and disorganized leadership contributed to the scale of our negative health outcomes.

All six said that Lavender had played a central role in the war, processing masses of data to rapidly identify potential “junior” operatives to target. Four of the sources said that, at one stage early in the war, Lavender listed as many as 37,000 Palestinian men who had been linked by the AI system to Hamas or PIJ.

The health ministry in the Hamas-run territory says 32,000 Palestinians have been killed in the conflict in the past six months. UN data shows that in the first month of the war alone, 1,340 families suffered multiple losses, with 312 families losing more than 10 members.

Several of the sources described how, for certain categories of targets, the IDF applied pre-authorised allowances for the estimated number of civilians who could be killed before a strike was authorised.

You probably use a device with a chip made by TSMC every day, but TSMC does not actually design or market those chips. That would have sounded completely absurd before the existence of TSMC. Back then, companies designed chips that they manufactured themselves. Chang’s radical idea for a great semiconductor company was one that would exclusively manufacture chips that its customers designed. By not designing or selling its own chips, TSMC never competed with its own clients. In exchange, they wouldn’t have to bother running their own fabrication plants, or fabs, the expensive and dizzyingly sophisticated facilities where circuits are carved on silicon wafers.

The innovative business model behind his chip foundry would transform the industry and make TSMC indispensable to the global economy. Now it’s the company that Americans rely on the most but know the least about

I wanted to know more about his decision to start a new company when he could have stopped working altogether. What I discovered was that his age was one of his assets. Only someone with his experience and expertise could have possibly executed his plan for TSMC. 

I remember when supporters of Operation Iraqi Freedom constantly hyped good news from the battlefield and minimized bad news — right until the bad news became so overwhelming

Before Bush changed tactics and reinforced American troops during the surge in 2007 and 2008, it sometimes felt disloyal in Republican circles to criticize the course of the war.

Could we have changed our military tactics sooner if we had been able to see the battlefield more clearly? Did paradigm blindness — the unwillingness or inability to accept challenges to our core ways of making sense of the world — inhibit our ability to see obvious truths?

Payments to thousands of former and current athletes will approach $2.8 billion, minus the trial lawyers’ cut of the class-action suits. This follows the NCAA’s decision to let college athletes benefit financially from their names, images and likenesses

Most legal analysis of the settlement concludes that the days of the “amateur” college athlete are over. In the future, the men and women on Division I teams and others likely will be regarded as professionals who will be paid to play by universities through revenue-sharing agreements up to $20 million a year per school.

A group of OpenAI insiders is blowing the whistle on what they say is a culture of recklessness and secrecy at the San Francisco artificial intelligence company, which is racing to build the most powerful A.I. systems ever created.

The group, which includes nine current and former OpenAI employees, has rallied in recent days around shared concerns that the company has not done enough to prevent its A.I. systems from becoming dangerous.

The members say OpenAI, which started as a nonprofit research lab and burst into public view with the 2022 release of ChatGPT, is putting a priority on profits and growth as it tries to build artificial general intelligence, or A.G.I., the industry term for a computer program capable of doing anything a human can.

The collapse of the five-year-old Observatory is the latest and largest of a series of setbacks to the community of researchers who try to detect propaganda and explain how false narratives are manufactured, gather momentum and become accepted by various groups

It follows Harvard’s dismissal of misinformation expert Joan Donovan, who in a December whistleblower complaint alleged he university’s close and lucrative ties with Facebook parent Meta led the university to clamp down on her work, which was highly critical of the social media giant’s practices.

Starbird said that while most academic studies of online manipulation look backward from much later, the Observatory’s “rapid analysis” helped people around the world understand what they were seeing on platforms as it happened.

This is not the first time our nation has survived a profound internal rupture, but it may be the first time in which the political ringleaders of the revolt may very well escape much accountability while hundreds of their followers serve jail time.

In previous times of national crisis, the same spirit of mercy that Mr. Biden conjured generally applied to lower-level offenders, while those who had committed the worst crimes were the first to be arrested and tried for their treasonous acts.

As a legal mechanism, oblivion promised the return to a past that still had a future, in which the battles of old would not predetermine those still to come. It did not always achieve its lofty aspirations, nor was it appropriate for all conflicts. But the ideals it grasped for had an enduring appeal.
