Navigator Research's poll, conducted April 24 to 28 among 1,000 registered voters, found about 1 in 9 (11 percent) of respondents who voted for Trump in 2024 regretted having done so, another 16 percent do not regret voting for him but were disappointed.

In an interview with PsyPost, lead study author Jesús Adrián-Ventura said that he and his team found that right-wing authoritarianism was associated with lower grey matter volume in the dorsomedial prefrontal cortex — a "region involved in understanding others' thoughts and perspectives," as the assistant Zaragoza psychology professor put it.

A grand experiment pitted two rival theories of consciousness against each other. Critics have condemned one of the two theories as pseudoscience, and have questioned whether the new study can deliver a clear verdict on either of them

The Trump administration has dismissed all the scientists and other authors working on the next National Climate Assessment.

The success of Large Language Models (LLMs) has sparked interest in various agentic applications. A key hypothesis is that LLMs, leveraging common sense and Chain-of-Thought (CoT) reasoning, can effectively explore and efficiently solve complex domains. However, LLM agents have been found to suffer from sub-optimal exploration and the knowing-doing gap, the inability to effectively act on knowledge present in the model. In this work, we systematically study why LLMs perform sub-optimally in decision-making scenarios. In particular, we closely examine three prevalent failure modes: greediness, frequency bias, and the knowing-doing gap. We propose mitigation of these shortcomings by fine-tuning via Reinforcement Learning (RL) on self-generated CoT rationales. Our experiments across multi-armed bandits, contextual bandits, and Tic-tac-toe, demonstrate that RL fine-tuning enhances the decision-making abilities of LLMs by increasing exploration and narrowing the knowing-doing gap. Finally, we study both classic exploration mechanisms, such as epsilon-greedy, and LLM-specific approaches, such as self-correction and self-consistency, to enable more effective fine-tuning of LLMs for decision-making.

“We’re taking care of their military. We’re taking care of every aspect of their lives, and we don’t need them to make cars for us,” Trump told Time. “In fact, we don’t want them to make cars for us. We want to make our own cars. We don’t need their lumber. We don’t need their energy. We don’t need anything from Canada. And I say the only way this thing really works is for Canada to become a state.”

U.S. Defense Secretary Pete Hegseth had an internet connection that bypassed the Pentagon’s security protocols set up in his office to use the Signal messaging app on a personal computer, two people familiar with the line told The Associated Press.

While Signal offers more protections than standard text messaging, it’s no guarantee of security. Officials also must ensure their hardware and connections are secure, said Theresa Payton, White House chief information officer under President George W. Bush and now CEO of Fortalice Solutions, a cybersecurity firm.

Water scarcity is a growing credit risk for data center operators, particularly hyperscale providers supporting AI workloads, a new report indicates.

Increased extreme heat is among the clearest impacts of global warming, but the economic effects of heat waves are poorly understood. Using subnational economic data, extreme heat metrics measuring the temperature of the hottest several days in each year, and an ensemble of climate models, we quantify the effect of extreme heat intensity on economic growth globally. We find that human-caused increases in heat waves have depressed economic output most in the poor tropical regions least culpable for warming. Cumulative 1992–2013 losses from anthropogenic extreme heat likely fall between $16 trillion and $50 trillion globally. Losses amount to 8% of Gross Domestic Product per capita per year for regions in the bottom income decile, but only 3.5% for regions in the top income decile. Our results have the potential to inform adaptation investments and demonstrate how global inequality is both a cause and consequence of the unequal burden of climate change.

A trawl of job views and application data suggests jobseekers are looking abroad as the Trump administration’s cuts to science take hold.

Effort suggests Moscow will not halt its counteroffensive at national border, should it recapture Russian territory

the Liberals win a majority in around 88%. A hung parliament occurs in around 11%, while a Conservative majority appears in around 1% of simulations.

“Thank you very much @elonmusk for giving me back my monetization tonight,” she wrote on X in February.

“You’re welcome,” Mr. Musk replied.

When Ms. Loomer lost her access to X Premium, she also lost the ability to earn money from her paid subscribers and from X’s revenue program, which shares ad dollars with premium users. She estimated in an interview that she lost about $50,000 from X during the period when her account was suppressed.

“I think it’s wrong to say it’s a free speech platform and then shut off people’s ability to monetize,” Ms. Loomer said.

the government’s previous fiscal anchors—declining debt-to-GDP and deficits below 1 percent of GDP—have now been clearly abandoned.

Seemingly, this is an unspoken understanding at the top AI companies. When one Meta researcher inquired if the company's legal team had okayed using LibGen, another responded: "I didn't ask questions but this is what OpenAI does with GPT3, what Google does with PALM, and what Deepmind does with Chinchilla so we will do it to[o]," per Vanity Fair, from internal messages cited in the suit.

Stimulating either of a pair of crucial nerves that carry messages from the brain to several major organs could be an effective way to treat people with severe depression.

The NDP would implement a one per cent tax on households with a net worth between $10 million and $50 million, two per cent for those worth $50 million to $100 million and three per cent for those over $100 million.

According to their platform, that would raise about $94.5 billion in revenue over four years. The party also says they can raise $24.8 billion by closing tax loopholes and another $8 billion by reducing the federal government's use of consultants.

Among supporters of Pierre Poilievre’s party, 59 per cent either said they feel “less safe” (48%) or “somewhat less safe” (11%) in their own neighbourhoods.

That’s compared to 26.5 per cent of Liberal voters, 23.6 per cent of NDP voters, and 18 per cent of Bloc Québécois voters.
