Discokeryx xiezhi was an early relative of today’s giraffes, but more like a cousin and not a direct ancestor.

“To the best of our knowledge, D. xiezhi exhibits the most optimized head-butting adaptation in vertebrate evolution,” the researchers write in the paper.

The discovery of Discokeryx xiezhi suggests this fighting style and competition for mates may be a contributing factor in their long-neck evolution.

“In reality, it was likely a combination of natural selection ... for a particular dietary preference and sexual selection in that lineage that drove the evolution of modern giraffe necks and limbs,” Advait Jukar, a paleobiologist at Yale University who was not involved in the study tells Scientific American’s Rachel Nuwer.

Ambiguities are often reconciled with other observed data, such as that we know by other means that the planet is too small to cause the scale of distortion seen.

“The two previous theories of degeneracy deal with cases where the background star appears to pass close to the foreground star or the foreground planet. The AI algorithm showed us hundreds of examples from not only these two cases, but also situations where the star doesn’t pass close to either the star or planet and cannot be explained by either previous theory,” said Zhang in a Berkeley news release.

But without the systematic and confident calculations of the AI, it’s likely the simplified, less correct theory would have persisted for many more years.

As a result — and after some convincing, since a grad student questioning established doctrine is tolerated but perhaps not encouraged — they ended up proposing a new, “unified” theory of how degeneracy in these observations can be explained, of which the two known theories were simply the most common cases.

“People were seeing these microlensing events, which actually were exhibiting this new degeneracy but just didn’t realize it. It was really just the machine learning looking at thousands of events where it became impossible to miss,” said Scott Gaudi

But Zhang seemed convinced that the AI had clocked something that human observers had systematically overlooked.

Just as people learned to trust calculators and later computers, we are learning to trust some AI models to output an interesting truth clear of preconceptions and assumptions — that is, if we haven’t just coded our own preconceptions and assumptions into them.

“The $150 million penalty reflects the seriousness of the allegations against Twitter, and the substantial new compliance measures to be imposed as a result of today’s proposed settlement will help prevent further misleading tactics that threaten users’ privacy.” 

The settlement is the latest attempt by U.S. law enforcers to apply consumer protection law to alleged data privacy violations.

“Keeping data secure and respecting privacy is something we take extremely seriously, and we have cooperated with the FTC every step of the way,” he added.

“Who are these people? This is not America,” Navarro said. “I was a distinguished public servant for four years.”

A Feb. 9 letter to Navarro from the House committee issued with the subpoena said the panel had reason to believe he had information relevant to the investigation in the riot and invasion of the Capitol, which disrupted for hours the certification by a joint session of Congress of the election of Biden.

Navarro called the circumstances of that arrest an example of “prosecutorial misconduct.”

Navarro argues in his suit that the committee was improperly created and that its subpoenas, as a result, are unenforceable.

Navarro is next due to appear in court on June 17.

The tech leaders question claims by crypto evangelists that “crypto-assets are an innovative technology that is unreservedly good” and instead urge lawmakers to “take a critical, skeptical approach” toward crypto.

"I have also been to events where five people sat dressed in the same way, each had a well-rehearsed stance, and then they do it again every time," he said. "And that's why I think that is not a discussion, that is not participation in a discussion, but an attempt to manipulate events for one's own purposes. One should not do this."

"Where does one begin? In just one half-sentence, the Chancellor of the Federal Republic relativizes the Nazi regime and, in a paradoxical way, also the climate crisis," she wrote on Twitter. "He stylizes climate protection as an ideology with parallels to the Nazi regime. In 2022. Jesus. This is such a scandal."

Prominent German Climate scientist Friederike Otto commented that "Scholz 'forgets' our worst history, dismisses every generation that comes after him as irrelevant & the audience just applauds."

The chancellor leads a three-party coalition with partners the Greens and pro-business Free Democrats, and their pledge to improve climate change action was central to their campaign.

“There are certain things that increase perception of risks,” Dr. Sell said. “One of these is risks to future generations. So rumors related to pregnancy are particularly gripping.

“We know pregnant individuals are at an increased risk when it comes to Covid-19, but they absolutely should not and do not have to die from it,” said Dr. Christopher Zahn

60 percent believed that pregnant women should not get the vaccine, or were unsure if this was true;

One reason misinformation about the vaccines and pregnancy may have gained so much traction, experts say, is that the earliest clinical trials of the coronavirus vaccines excluded pregnant women. The lack of trial data led the C.D.C. and World Health Organization to initially give different recommendations to pregnant women, though neither explicitly forbade, nor encouraged, immunizing pregnant women. Other health organizations chose to wait for more safety data from later trials before making an official recommendation for pregnant women to get vaccinated.

“At the root of this problem is trust, or really, it’s a lack of trust,” Dr. Sell said.

The state law, referred to as HB 20, makes it illegal for large social networks like Facebook and Twitter to "block, ban, remove, de-platform, demonetize, de-boost, restrict, deny equal access or visibility to, or otherwise discriminate against expression."

HB 20 does carve out exemptions, including those that allow social networks to remove content that "directly incites criminal activity or consists of specific threats of violence targeted against a person or group" based on certain characteristics, or that "is unlawful expression."

We need to fix social networks by removing toxic content. This month's appeals court ruling does the exact opposite and could even deal a fatal blow to social media as we know it. The only thing worse than not fixing the social platforms we have now would be to see them be subject to a constant slew of lawsuits or devolve into platforms that become bastions of hate speech and misinformation. Let's hope Congress doesn't let us down.

Albert Fox Cahn, founder and executive director of the Surveillance Technology Oversight Project and a fellow at the NYU School of Law, said the findings add to mounting concerns around the collection of data among young people. In recent months, there has been intense scrutiny from lawmakers about the impact tech platforms have on teens.

"We already knew technologies were being abused and putting children at risk, but this report is really important because it shows the scale of harm and how the same mistake is being made by educators and governments around the world," he said.

"Students must be able to do their schoolwork without surveillance by companies looking to harvest their data to pad their bottom line," said Samuel Levine

"The data must serve a purpose, but the purpose cannot be advertising," he said. "If it is not something we do in physical classrooms, it is not something that should be part of digital school life."

At the same time, it was not immediately clear how some of the other groundbreaking work, like language models that better understand natural conversation or that can break down a task into logical smaller steps, will ultimately lead to the next generation of computing that Google has touted.

Much of those capabilities are powered by the deep technological work Google has done for years using so-called machine learning, image recognition and natural language understanding. It’s a sign of an evolution rather than revolution for Google and other large tech giants.

“There is so much technology out there that employers are experimenting with or investing in,” said Edgar Ndjatou

Software can watch for suspicious computer behavior or it can dig into an employee’s credit reports, arrest records and marital-status updates. It can check to see if Cheryl is downloading bulk cloud data or run a sentiment analysis on Tom’s emails to see if he’s getting testier over time. Analysis of this data, say the companies that monitor insider risk, can point to potential problems in the workplace.

Organizations that produce monitoring software and behavioral analysis for the feds also may offer conceptually similar tools to private companies, either independently or packaged with broader cybersecurity tools.

But corporations are moving forward with their own software-enhanced surveillance. While private-sector workers may not be subjected to the rigors of a 136-page clearance form, private companies help build these “continuous vetting” technologies for the federal government, said Lindy Kyzer of ClearanceJobs. Then, she adds, “Any solution would have private-sector applications.”

“Can we build a system that checks on somebody and keeps checking on them and is aware of that person’s disposition as they exist in the legal systems and the public record systems on a continuous basis?” said Chris Grijalva

But the interest in anticipating insider threats in the private sector raises ethical questions about what level of monitoring nongovernmental employees should be subject to.

“People are starting to understand that the insider threat is a business problem and should be handled accordingly,” said Mr. Grijalva.

The linguistic software package they developed, called SCOUT, uses psycholinguistic analysis to seek flags that, among other things, indicate feelings of disgruntlement, like victimization, anger and blame.

“The language changes in subtle ways that you’re not aware of,” Mr. Stroz said.

There’s not enough information, in other words, to construct algorithms about trustworthiness from the ground up. And that would hold in either the private or the public sector.

Even if all that dystopian data did exist, it would still be tricky to draw individual — rather than simply aggregate — conclusions about which behavioral indicators potentially presaged ill actions.

“Depending too heavily on personal factors identified using software solutions is a mistake, as we are unable to determine how much they influence future likelihood of engaging in malicious behaviors,” Dr. Cunningham said.

“I have focused very heavily on identifying indicators that you can actually measure, versus those that require a lot of interpretation,” Dr. Cunningham said. “Especially those indicators that require interpretation by expert psychologists or expert so-and-sos. Because I find that it’s a little bit too dangerous, and I don’t know that it’s always ethical.”

Recent episodes have focused on mainstream tech stories — the crypto crash, the Netflix bubble bursting — but others go down truly weird rabbit holes, like the mysterious world of Katie Couric CBD scams on Facebook.

Delving into the deepest recesses of the dark web, “Hunting Warhead” follows a monthslong investigation by Einar Stangvik, the hacker, and Hakon Hoydal, the journalist, that ultimately led to the downfall of a local politician.

In a bizarre twist, the hack turned out to be motivated by the impending release of a movie named “The Interview,” (starring Seth Rogen and James Franco), which depicted a fictional plot to assassinate Kim Jong-un of North Korea.

This wry, richly reported podcast from the BBC World Service chronicles every twist and turn of the saga and its implications far beyond Hollywood.

Quantum teleportation — what he called “spooky action at a distance” — can transfer information between locations without actually moving the physical matter that holds it.

This technology could profoundly change the way data travels from place to place. It draws on more than a century of research involving quantum mechanics, a field of physics that governs the subatomic realm and behaves unlike anything we experience in our everyday lives. Quantum teleportation not only moves data between quantum computers, but it also does so in such a way that no one can intercept it.

These entangled systems could be electrons, particles of light or other objects. In the Netherlands, Dr. Hanson and his team used what is called a nitrogen vacancy center — a tiny empty space in a synthetic diamond in which electrons can be trapped.

Traditional computers perform calculations by processing “bits” of information, with each bit holding either a 1 or a 0. By harnessing the strange behavior of quantum mechanics, a quantum bit, or qubit, can store a combination of 1 and 0 — a little like how a spinning coin holds the tantalizing possibility that it will turn up either heads or tails when it finally falls flat on the table.

Researchers believe these devices could one day speed the creation of new medicines, power advances in artificial intelligence and summarily crack the encryption that protects computers vital to national security. Across the globe, governments, academic labs, start-ups and tech giants are spending billions of dollars exploring the technology.

Although it cannot move objects from place to place, it can move information by taking advantage of a quantum property called “entanglement”: A change in the state of one quantum system instantaneously affects the state of another, distant one.

“It does not work that way today. Google knows what you are running on its servers.”

The information also cannot be intercepted. A future quantum internet, powered by quantum teleportation, could provide a new kind of encryption that is theoretically unbreakable.

ght social networks like Gettr and Rumble, and mainstream social media sites to root out early misinformation narratives about voting before they go viral, and then urge the companies to remove or flag the posts that contain false information.

These states, most of them under Democratic control, have been acting as voter confidence in election integrity has plummeted.

In an ABC/Ipsos poll from January, only 20 percent of respondents said they were “very confident” in the integrity of the election system and 39 percent said they felt “somewhat confident.”

Some conservatives and civil rights groups are almost certain to complain that the efforts to limit misinformation could restrict free speech.

“State and local governments are well situated to reduce harms from dis- and misinformation by providing timely, accurate and trustworthy information,” said Rachel Goodman

“Facts still exist, and lies are being used to chip away at our fundamental freedoms,” Ms. Griswold said.

Officials said they would prefer candidates fluent in both English and Spanish, to address the spread of misinformation in both languages. The officer would track down viral misinformation posts on Facebook, Instagram, Twitter and YouTube, and look for emerging narratives and memes, especially on fringe social media platforms and the dark web.

The 23-year-old Zuckerberg hired Sandberg in 2008 to figure out how to build Facebook into a large and lasting business.

Sandberg spearheaded a plan to build from scratch a more sophisticated system of advertising that was largely based on what she had helped develop at Google. Ads on Facebook were tied to people’s activities and interests on the site. As at Google, many advertisers bought Facebook ads online rather than through sales personnel, as had been typical for TV or newspaper ads. Later, Sandberg cultivated new systems for Facebook advertisers to pinpoint their potential customers with even more precision.

Google and Facebook transformed product marketing from largely an art to a sometimes creepy science, and Sandberg is among the architects of that change. She shares in the credit (or blame) for developing two of the most successful, and perhaps least defensible, business models in internet history.

All the anxiety today about apps snooping on people to glean every morsel of activity to better pitch us dishwashers — that’s partly Sandberg’s doing. So are Facebook and Google’s combined $325 billion in annual advertising sales and those of all other online companies that make money from ads.

In their 2021 book, “An Ugly Truth,” Sheera and Cecilia wrote that to Sandberg’s detractors, her response was part of a pattern of trying to preserve the company’s reputation or her own rather than do the right thing.

A common refrain in battles about Covid-19 and vaccination, politics and conspiracy theories, parenting, drugs, food, stock trading and media, it signals not just a rejection of authority but often trust in another kind.

“Do your own research” is an idea central to Joe Rogan’s interview podcast, the most listened to program on Spotify, where external claims of expertise are synonymous with admissions of malice. In its current usage, DYOR is often an appeal to join in, rendered in the language of opting out.

“There’s this idea that the goal of science is consensus,” Professor Carrion said. “The model they brought to it was that we didn’t need consensus.” She noted that the women she surveyed often used singular rather than plural pronouns. “It was ‘she needs to do her own research,” Professor Carrion said, rather than we need to do ours. Unlike some critical health movements in the past, this was an individualist endeavor.

One of the enticing aspects of cryptocurrencies, which pose an alternative to traditional financial institutions, is that expertise is available to anyone who wants to claim it.

In crypto, the uses of DYOR are various and contradictory, earnest and ironic sometimes within the same discussion. Breathless investment pitches for new coins are punctuated with “NFA/DYOR” (not financial advice), or admonitions not to invest more than you can afford to lose, which many people are obviously ignoring; stories about getting rich are prefaced with DYOR; requests for advice about which coins to hold are answered with DYOR. It is the siren song of crypto investing.

In that way — the momentum of a group — crypto investing isn’t altogether distinct from how people have invested in the stock market for decades. Though here it is tinged with a rebellious, anti-authoritarian streak: We’re outsiders, in this together; we’re doing something sort of ridiculous, but also sort of cool.

“Now it seems like DYOR can only do so much,” the user wrote. Eventually, the user said, you end up relying on “trust.”

It also comes amid an ongoing, global battle over the future of platform moderation, with officials in Europe seeking to heighten standards surrounding tech companies' content decision-making and lawmakers in many US states seeking to force platforms to moderate less.

The former president also compared Ukrainian leader Volodymyr Zelenskyy to Britain’s wartime leader Winston Churchill, while condemning Russian President Vladimir Putin for launching the invasion of Ukraine in February.

Now, numerous advertising executives say they’re willing to move their money elsewhere, especially if Mr. Musk eliminates the safeguards that allowed Twitter to remove racist rants and conspiracy theories.

“At the end of the day, it’s not the brands who need to be concerned, because they’ll just spend their budgets elsewhere — it’s Twitter that needs to be concerned,” said David Jones

On Wednesday night, at Twitter’s annual NewFronts presentation for advertisers at Pier 17 in New York, company representatives stressed Twitter’s value for marketers: as a top destination for people to gather and discuss major cultural moments like sporting events or the Met Gala, increasingly through video posts.

Twitter differs from Facebook, whose millions of small and midsize advertisers generate the bulk of the company’s revenue and depend on its enormous size and targeting abilities to reach customers. Twitter’s clientele is heavily weighted with large, mainstream companies, which tend to be wary of their ads appearing alongside problematic content.

Twitter earns the vast majority of its ad revenue from brand awareness campaigns, whose effectiveness is much harder to evaluate than ads that target users based on their interests or that push for a direct response, such as clicking through to a website.

Twitter’s reach is also narrower than many rivals, with 229 million users who see ads, compared with 830 million users on LinkedIn and 1.96 billion daily users on Facebook.

“Even the likes of LinkedIn have eclipsed the ability for us to target consumers beyond what Twitter is providing,” he said. “We’re going to go where the results are, and with a lot of our clients, we haven’t seen the performance on Twitter from an ad perspective that we have with other platforms.”

“Twitter’s done a better job than many platforms at building trust with advertisers — they’ve been more progressive, more responsive and more humble about initiating ways to learn,” said Mark Read

On Twitter, he has criticized ads as “manipulating public opinion” and discussed his refusal to “pay famous people to fake endorse.”

“There’s a fork in the road, where Path A leads to an unfiltered place with the worst of human behavior and no brands want to go anywhere near it,” said Mr. Jones of Brandtech. “And Path B has one of the world’s genius entrepreneurs, who knows a lot about running companies, unleashing a wave of innovation that has people looking back in a few years and saying, ‘Remember when everyone was worried about Musk coming in?’”

They communicated without knowing the same language but as my mother learned English, she had a very heavy accent and still does to this day at the age of 91.

There are children in every classroom learning a language — whether it's English or not. Everywhere in the world with refugees dispersed, people are learning new languages and adapting to new homes.

As we mature and then go to school and encounter people from all different backgrounds, it's kind of a shock for anybody in any language to seek a sense of belonging with people who aren't from your family, people you don't know. And yet there are these universal languages, like poetry, which is musical and is rooted in emotions. And I feel like that's a refuge.

For me, when I think of where have I ever had a sense of belonging, I have a sense of belonging on the page.
