"Face the Nation" host Margaret Brennan asked Trump Commerce Secretary Howard Lutnick whether AI helped construct some of the tariff policies. CBS' Margaret Brennan asked Secretary of Commerce Howard Lutnick whether artificial intelligence was involved in designing President Donald Trump's broad tariff policies on Sunday. The "Face the Nation" host confronted Lutnick on Trump's "Liberation Day" announcement, which saw significant tariff increases across numerous countries. This included a baseline tariff of 10% on all U.S. imports that began on Saturday. The announcement caused chaos for investors as the stock market suffered some of its worst losses since the COVID pandemic in 2020.

Editor's Note: This article contains discussions related to child sexual abuse and pornography. Child predators are on high alert as organizations around the globe have begun rolling out artificial intelligence (AI) tools to bring sex traffickers to justice and rescue young victims, according to "Sound of Freedom" executive producer Paul Hutchinson. Hutchinson, who has led 70 undercover rescue missions across 15 countries, told Fox News Digital on Wednesday that he has worked with "black hat" hackers to help identify child predators and bring them to justice. These guys are some of the best hackers anywhere. Some of them do highly illegal things for the right reasons, right?

Extinction is a part of nature. Of the five billion species that have existed on Earth, 99.9 per cent have vanished. The Triassic-Jurassic extinction, two hundred million years ago, finished off the crocodile-like phytosaur. Sixty-six million years ago, the end-Cretaceous extinction eliminated the Tyrannosaurus rex and the velociraptor; rapid climate change from an asteroid impact was the likely cause. The Neanderthals disappeared some forty thousand years ago. One day--whether from climate change, another asteroid, nuclear war, or something we can't yet imagine--humans will probably be wiped out, too.

Over the past three decades, Hicks has watched the Pentagon transform--politically, strategically, and technologically. She entered government in the 1990s at the tail end of the Cold War, when optimism and a belief in global cooperation still dominated US foreign policy. After 9/11, the focus shifted to counterterrorism and nonstate actors. Then came Russia's resurgence and China's growing assertiveness. Hicks took two previous breaks from government work--the first to complete a PhD at MIT and joining the think thank Center for Strategic and International Studies (CSIS), which she later rejoined to lead its International Security Program after her second tour. "By the time I returned in 2021," she says, "there was one actor--the PRC (People's Republic of China)--that had the capability and the will to really contest the international system as it's set up."

A "quiet crisis" is emerging at the U.S.-Canada border, as one expert proposes an unconventional solution to fight human smuggling: leveraging advanced technologies like artificial intelligence. While national attention is largely fixed on the southern border, an increasingly concerning situation is unfolding along the country's northern border, said Jon Brewton, the founder and CEO of Data2 and a U.S. Air Force Veteran. "U.S. Customs and Border Patrol has seen a fairly alarming increase in illegal crossings, drug trafficking, and even encountering individuals on the terrorist watch list," he told Fox News Digital. "And as difficult as securing the southern border has been, the northern border is twice as long." While the vast majority of illegal crossings happen at the southern border, officials have been warning for years that the northern line has seen an increase.

Russia's Defence Ministry said its air defence units "intercepted and destroyed" 11 Ukrainian drones over the country's Kursk and Belgorod regions, which border Ukraine, as well as the southern Rostov region overnight. Russia's Defence Ministry said Kyiv carried out seven attacks on Moscow's energy infrastructure facilities between April 5 and 6, despite a moratorium on energy strikes brokered by the United States. According to the ministry, the attacks targeted the Crimean region, which Russia annexed from Ukraine in 2014, as well as Russia's Bryansk, Rostov and Voronezh regions. The ministry also said that Kremlin forces launched an overnight strike using long-range precision weapons and drones against Ukraine's central artillery armament base and defence industry enterprises involved in drone production. According to the ministry, Moscow also gained control over the village of Basivka in Ukraine's Sumy region in a rare cross-border advance.

One person was killed Sunday as Russian air strikes hit the Ukrainian capital, Kyiv, while the death toll from Friday's deadly attack on the central Ukrainian city of Kryvyi Rih continued to rise. The Kyiv victim was found close to the strike's epicenter of the attack in the city's Darnytskyi district, Mayor Vitali Klitschko said. A further three people were injured in the strike, which saw fires break out in several nonresidential areas, damaging cars and buildings. In a statement on social media, Ukrainian President Volodymyr Zelenskyy said the intensifying Russian attacks showed that there is still insufficient international pressure on Moscow.

Generation planning approaches face challenges in managing the incompatible mathematical structures between stochastic production simulations for reliability assessment and optimization models for generation planning, which hinders the integration of reliability constraints. This study proposes an approach to embedding reliability verification constraints into generation expansion planning by leveraging a weighted oblique decision tree (WODT) technique. For each planning year, a generation mix dataset, labeled with reliability assessment simulations, is generated. An WODT model is trained using this dataset. Reliability-feasible regions are extracted via depth-first search technique and formulated as disjunctive constraints. These constraints are then transformed into mixed-integer linear form using a convex hull modeling technique and embedded into a unit commitment-integrated generation expansion planning model. The proposed approach is validated through a long-term generation planning case study for the Electric Reliability Council of Texas (ERCOT) region, demonstrating its effectiveness in achieving reliable and optimal planning solutions.

Recently, linear regression models incorporating an optimal transport (OT) loss have been explored for applications such as supervised unmixing of spectra, music transcription, and mass spectrometry. However, these task-specific approaches often do not generalize readily to a broader class of linear models. In this work, we propose a novel algorithmic framework for solving a general class of non-negative linear regression models with an entropy-regularized OT datafit term, based on Sinkhorn-like scaling iterations. Our framework accommodates convex penalty functions on the weights (e.g. squared-$\ell_2$ and $\ell_1$ norms), and admits additional convex loss terms between the transported marginal and target distribution (e.g. squared error or total variation). We derive simple multiplicative updates for common penalty and datafit terms. This method is suitable for large-scale problems due to its simplicity of implementation and straightforward parallelization.

The biggest news this week is inarguably the Trump administration's baffling tariffs, which have rattled the global economy, impacting everything from the US tech industry to literal penguins, leaving most of the world wondering what comes next. But if you're looking for a mystery that doesn't feel quite so, well, existential, look no further than Indiana University. On March 18, the FBI raided the homes of Xiaofeng Wang, a data privacy professor and researcher who worked at the IU for more than 20 years. The same day, according to a termination email viewed by WIRED, Wang was fired from his job, and people soon noticed that he and his wife seemed to have disappeared. A WIRED investigation found that the university was looking into whether Wang received unreported research funding from China prior to his position being terminated.
