Physicists consider black holes one of the most mysterious objects that exist. Ironically, they’re also considered one of the simplest. For years, physicists have been looking to prove that black holes are more complex than they seem. And a newly approved European space mission called LISA will help with this hunt.

Eighty years ago, on a day now known as D-Day, thousands of Allied soldiers crossed the choppy waters of the English Channel by air and sea to land on beaches and coastal areas of Normandy, France, to destroy the Nazi invaders and defeat Hitler’s regime. Within the military collections of the National Museum of American History, several artifacts collected over the decades help tell the story of Omaha Beach and the invasion landings on D-Day.

You can spot them in the streets of Paris or at fashion events in London, Milan, Brussels or Dubai. Most are black African men with sharp outfits designed and chosen to get them noticed. Known as “Sapeurs” – the name comes from the Society for Ambience and Elegance (Sape) and from French slang “se saper”, “to dress up” – these figures stand out with their offbeat and baroque sartorial style.

Colombia’s is seen as the most comprehensive peace accord that has been signed to date. It considers issues ranging from security to social justice and political participation, in great detail. The accord acknowledges that a peaceful postwar society requires not only respect for human rights but also “protection of the environment, respect for nature and its renewable and nonrenewable resources and biodiversity.”

The U.S. Drug Enforcement Agency announced in late April 2024 that it plans to ease federal restrictions on cannabis, reclassifying it from a Schedule I drug to the less restricted Schedule III, which includes drugs such as Tylenol with codeine, testosterone and other anabolic steroids. Similarly, the FDA granted a breakthrough therapy designation to psilocybin to expedite drug development. Preliminary studies suggest it may have substantial therapeutic value for treatment-resistant depression and major depressive disorder.

Concern in Tehran over the death of Iranian President Ebrahim Raisi may extend beyond the potential human tragedy of the crash. The change forced by it will have important implications for an Iranian state that is consumed by domestic chaos, and regional and international confrontation.

America’s first large-scale offshore wind farms began sending power to the Northeast in early 2024, but a wave of wind farm project cancellations and rising costs have left many people with doubts about the industry’s future in the U.S. Altogether, projects that had been canceled by the end of 2023 were expected to total more than 12 gigawatts of power, representing more than half of the capacity in the project pipeline. So, what happened, and can the U.S. offshore wind industry recover?

Since the start of the war in Gaza, Israel, Hezbollah and other armed groups in Lebanon have exchanged almost 5,000 attacks across the border. Lebanon is being pulled into a war it cannot afford. But the country’s weak state has little power against the militias that operate within its territory, among them a private militia named Jnoud al-Rab (Soldiers of God). It is a far-right, Christian group made up primarily of young working-class men who see themselves as “guardian angels.”

EV safety is that crash test results, field injury data and injury claims from the Insurance Institute for Highway Safety all reveal that EVs are superior to their internal combustion counterparts in protecting their occupants. While the inherent weightiness of EVs offers a natural advantage in protecting occupants, it also means that other vehicles bear the burden of absorbing more crash energy in collisions with heavier EVs. This dilemma is central to the concept of “crash compatibility,” a well-established field of safety research.

Mounting evidence now suggests how you spend your day can have meaningful ramifications for your health. In addition to moderate-to vigorous-intensity physical activity, this means the time you spend sitting, standing, doing light physical activity (such as walking around your house or office) and sleeping.

The extreme consequences of unfounded conspiratorial beliefs could be seen on the staircases of the U.S. Capitol on Jan. 6, 2021, and in the self-immolation of a protestor outside the courthouse holding the latest Trump trial. But if hidden forces really are at work in the world, how is someone to know what’s really going on?

A child aged under ten has about a 40% greater chance of living until their next birthday, compared to if we didn’t have vaccines. And these positive effects can be seen well into adult life. A 50-year-old has a 16% greater chance of celebrating their next birthday thanks to vaccines.

Trump says that he can replicate the 1950s’ failed Operation Wetback on a much grander scale by setting up temporary immigration detention centers and relying on local, state and federal authorities, including National Guard troops, to remove the estimated 11 million undocumented immigrants now living in the U.S. Trump’s proposal is disturbing and misleading.

The federal hate-crime law is ineffective at both accumulating data and enforcing penalties. Not only was the first federal conviction for a hate crime on the basis of gender identity made 15 years after the law’s passage, but hate crimes generally are also subject to chronic underreporting.

To the students taking part they are, in the words of one protester, “uplifting the voices of Gazans, of Palestinians facing genocide.” But to many people outside the universities, the focus has been on confrontations and arrests. Where does this disconnect come from? Most people don’t participate in on-the-streets protests or experience any of the disruption that they cause. Rather they rely on the media to give a full picture of the protests.

The two major parties have largely run minor-party competitors out of business in intentional ways. Democratic and Republican officeholders adopt laws making it more difficult for others to run. But although a third party is not likely to have much electoral success anytime soon, they do enrich American politics.

Israel entered Rafah, a city that marks Gaza’s southern border crossing with Egypt, on May 7, 2024, launching a military offensive that the U.S. and others have cautioned Israel not to pursue. As always, Israel ignored the cautions and pressed on, running up the mass-killing tally despite Hamas accepting a cease-fire proposal.

Researchers who run the American Communities Project, which explores the differences in 15 different types of community in the United States, believe the surveys are asking a question with no real meaning in the United States in 2024 – a question that may have outlived its usefulness.

A Vatican declaration, the “Infinite Dignity,” opposes gender-affirming surgery and surrogacy. Yet even in the ancient Roman Empire, individuals could transgress traditional conceptions of gender roles in various ways. While Roman notions of femininity and masculinity were strict as regards clothing, for instance, there is evidence to suggest that individuals could and did breach these norms, although they were likely to be met with ridicule or scorn.

The global coffee shop chain is challenging the NLRB, the federal agency responsible for enforcing U.S. workers’ rights to organize, saying that the agency used the more labor-friendly of two available standards when it asked a federal court to order the company to reinstate workers at a Memphis, Tennessee, store who lost their jobs in 2022 amid a nationwide unionizing campaign.

AI-generated content has become another “weird trick.” It’s visually appealing and cheap to produce, allowing scammers and spammers to generate high volumes of engaging posts. Much of the content is still clickbait: Shrimp Jesus makes people pause to gawk and inspires shares purely because it is so bizarre. Facebook is encouraging it.

The protesters are demanding divestment, meaning the sale of financial assets either related to Israeli companies or shares in other corporations perceived to assist the Israeli military. In addition, many protests include calls for the disclosure of those financial ties. They also feature demands for colleges and universities to distance themselves from Israel by ending study-abroad programs and academic exchanges.

There are arguments for and against increasing legalization of cannabis for adult use in the U.S., but expanded access to legal cannabis also may have unintended consequences for adolescents. These consequences are compounded by the increasing potency of some cannabis products.

The right-wing political campaign against diversity, equity and inclusion policies taking place in several states across the U.S. has called into question the nation’s commitment to achieving racial equality. In this landscape, Seattle is marking a milestone of sorts – the first anniversary of adopting its Race and Social Justice Initiative ordinance.

Throughout the 1960s and into the 1970s, conservative activists led a counterattack against campus antiwar and civil rights demonstrators by demanding action from college presidents and police. College presidents routinely caved to the demands of conservative legislators, angry taxpayers and other wellsprings of anticommunist outrage against students striking for peace and civil rights. They’re doing it again regarding Gaza-war protesters.

When the Supreme Court overturned the constitutional right to get an abortion in June 2022, Justice Clarence Thomas suggested that the court “should reconsider” other rights it currently recognizes – like the rights for same-sex couples to have sex and marry. If the Supreme Court overturns legal precedents on these and other issues, old state laws that haven’t been enforced, possibly for centuries, can suddenly spring back to life.

While Reagan and Trump – two of the most media-savvy Republican presidents – used religion to advance their political visions, their messages and missions are starkly different. Trump’s religious vision is rooted in white Christian nationalism, the belief that the white Christians who founded America hoped to spread Protestant beliefs and ideals. According to white Christian nationalists, the founders also wanted to limit the influence of non-Christian immigrants and enslaved Africans.

How do we account for other language-based forms of expression? If performed works such as theatre or songwriting can be considered literature, where is the limit? And why aren’t video games considered a form of expression?

In journalism school, students learn their craft while engaging with critical questions about their roles and responsibilities. They are often taught by previous or current journalists, whose work experiences prepare them to help students tackle reporting challenges. Crises ask journalism educators, students and practitioners to grapple with sharing stories about what the future could hold. What will journalists’ jobs look like in five years? Or 25 years?

Even just a decade ago, sea ice reliably rebuilt itself each winter. But something has changed in how the Southern Ocean works and the area covered by sea ice has decreased dramatically.

One track on Taylor Swift’s new album, “The Tortured Poets Department,” honors a long-celebrated, oft-miscast heroine of American feminism: actress Clara Bow. Bow was a woman way ahead of her time, a star who owned her success and her sexuality. There’s the popular perception that Bow was a victim of her own demons. But her story is anything but a cautionary tale.

A study makes clear that middle-aged Americans today are experiencing more loneliness than their peers in European nations. This coincides with existing evidence that mortality rates are rising for working-age adults in the U.S.

The Israeli army used a new artificial intelligence (AI) system to generate lists of tens of thousands of human targets for potential airstrikes in Gaza. One intelligence officer said the system “made it easier” to carry out large numbers of strikes, because “the machine did it coldly”.

Iran’s unprecedented multi-front attack on Israel constitutes a de facto declaration of war and marks the first direct assault against Israel from Iranian soil. However, despite the scale of the operation, it appears to be a tactical failure.

Over a decade ago, a United Nations report described the Gaza Strip as virtually unlivable, adding that it would require “Herculean efforts” to change that. Today, after six months of bombardment, mass displacement and siege by Israel, the task of rebuilding Gaza seems practically unimaginable.

The Dune films remind us of just how beautiful, mysterious, expansive and changeable sand dunes can be. For centuries these wonderful landforms have filled humans with awe – and in some cases fear and foreboding – because of the apparent remoteness and risks associated with the deserts they are synonymous with.

The most important guest voice on Beyoncé’s’s album is the one least likely to be familiar to Beyoncé’s listeners: Linda Martell, the first commercially successful Black female country music artist. Two tracks on “Cowboy Carter,” “Spaghettii” and “The Linda Martell Show,” include spoken word commentary from Martell. By giving Martell a platform, Beyoncé simultaneously gives credit to her predecessor while staking her own place in the country music tradition.

Trump lashes out when politicians and journalists bring us closer to truth. Stewart criticizes them for keeping us in the dark. To Stewart, the solutions to America’s political spectacle are political accountability and increased transparency. To Trump, the solution is far simpler: He alone can fix it.

A Home Depot store violated labor law when it disciplined Antonio Morales, the National Labor Relations Board ruled. Morales, a Home Depot employee in the Minneapolis area, had drawn the letters BLM on a work apron and refused to remove them. The Home Depot decision establishes an important precedent for workers who express broad concerns about systemic racism.

Finland steadily ranks as the happiest country in the world. In March 2024 the country was, for the seventh year in a row, ranked as the happiness champion. The ranking is based on one simple question, using a ladder metaphor, that is asked to people across nearly every country in the world. But it may not be an objective question.
