While fasting can influence metabolism, immunity and some aspects of cell growth, there is no credible evidence that prolonged water fasting can treat or cure cancer. Cancer itself often leads to malnutrition, and fasting can accelerate wasting (cachexia), weaken the immune system and increase susceptibility to infection. Many cancer patients are undergoing chemotherapies that require adequate nutrition to maintain organ function and safely metabolise drugs.

In a 2022 survey of 3,000 U.S. adults, more than one-third of respondents reported that on most days, they feel “completely overwhelmed” by stress. Pet dogs help humans feel more relaxed. This would explain the growing phenomenon of people relying on emotional support dogs to assist them in navigating everyday life. Dog owners have also been shown to have a 24% lower risk of death and a four times greater chance of surviving for at least a year after a heart attack.

About one-third of U.S. nonprofit service providers experienced a disruption in their government funding in the first half of 2025. These organizations run food pantries, deliver job training and offer mental health services. They provide independent living assistance, disaster relief and emergency shelter, among other services.

A largely overlooked directive issued by the Trump administration marks a major shift in U.S. counterterrorism policy, one that threatens bedrock free speech rights enshrined in the Bill of Rights. National Security Presidential Memorandum/NSPM-7, issued on Sept. 25, 2025, is a presidential directive that for the first time appears to authorize preemptive law enforcement measures against Americans based not on whether they are planning to commit violence but for their political or ideological beliefs.

Numerous studies have established that sex is not just male or female. Rather, it is a continuum that emerges from a person’s genetic makeup. Nonetheless, misconceptions persist that same-sex attraction is a choice that warrants condemnation or conversion, and leads to discrimination and persecution.

Since the truce was announced on Nov. 27, 2024, there have been more than 10,000 Israeli air and ground violations inside Lebanese territory, according to the latest report from UNIFIL, the United Nations peacekeeping mission in Lebanon. And in the run-up to the ceasefire’s first anniversary, a spate of Israeli strikes over its northern border saw the assassination of Hezbollah’s top military commander and a deadly attack on a Palestinian refugee camp.

George Orwell’s dystopian novels “Animal Farm” and “1984” have remained popular in the U.S. ever since their initial publication in the 1940s. What’s less well known is that in the years before the publication of “Animal Farm” and “1984,” Orwell’s writing often focused primarily on other themes including work, poverty, anti-imperialism and democratic socialism. In fact, Orwell remained a committed democratic socialist until his death in 1950.

Fuentes is a 27-year-old livestreamer with openly antisemitic views. He has called Adolf Hitler both “awesome” and “right.” But he has become impossible for the Republican Party to banish, despite repeated attempts by some party leaders. This dynamic reveals how fringe ideologies operate differently today compared to the mid-20th century, when institutional gatekeepers – political parties, law enforcement, the media – could more effectively contain extremist movements.

$1 trillion is an absurd amount of money – even for someone who is already the richest person in the world. So how do we make sense of it? Tesla’s chair of the board Robyn Denholm warned shareholders that Musk might walk away from the company if they didn’t approve the unprecedented pay package. Shareholder confidence was no doubt buoyed by the recent rise in Tesla’s stock, with one investor describing Musk as “key” to the entire enterprise.

A study finds roughly 1 in 5 Floridians are struggling with moderate to severe anxiety, which is consistent with national statistics. Anxiety was lowest among those who use social media primarily to stay connected with family and friends. But it rose significantly among those who use social media to stay up to date with current trends and pop culture or to learn about health, fitness and beauty trends.

Nine in 10 Americans gather around a table to share food on Thanksgiving. Popular interpretations of Thanksgiving also have also pulled us apart. The emphasis on the Pilgrims’ 1620 landing and 1621 feast erased a great deal of religious history and narrowed conceptions of who belongs in America – at times excluding groups such as Native Americans, Catholics and Jews.

American colleges and universities are increasingly firing or punishing professors and other employees for what they say, whether it’s on social media or in the classroom. For decades, American colleges and universities have traditionally encouraged free speech and open debate as a core part of their academic mission. But the First Amendment only applies to the government – which includes public colleges and universities – and not private institutions or companies, including private colleges and universities.

The Trump administration on Nov. 20, 2025, formally presented Ukraine with a 28-point proposal to end the war, and President Donald Trump announced the country had until Thanksgiving to sign it. The Trump administration was accused by policy experts and some lawmakers of fashioning a plan to serve Russia’s interests, and Secretary of State Marco Rubio got enmeshed in an argument with U.S. senators over whether the U.S. or Russia had authored the document.

If discrimination against white Americans were widespread, you might expect large numbers to report being treated unfairly. But polling data shows otherwise. A 2025 Pew survey found that 70% of white Americans think Black people face “some” or “a lot” of discrimination in general, and roughly two-thirds say the same of Asian and Hispanic people. Meanwhile, only 45% of white Americans believe that white people in general experience that degree of discrimination.

For more than 20 years, hormone therapy for menopause has carried a warning label from the Food and Drug Administration describing the medication’s risk of serious harms – namely, cancer, cardiovascular disease and possibly dementia. No longer. On Nov. 10, 2025, the FDA announced that drugmakers should remove these “black box” safety warnings. Here’s how the decision will affect health care for people going through menopause or postmenopause.

Shortly before COP30 talks begin in Brazil, tech billionaire and philanthropist Bill Gates has launched a “narrative grenade” into the discourse of climate politics by publishing a lengthy memo calling for a rethink of how the climate crisis is framed and addressed. Gates calls for a “strategic pivot” in climate strategy. That appears to have hit a nerve. Both social and traditional media were ablaze with erroneous assertions about Gates’ supposed reversal of opinion on climate change.

In August 2025, the city of Philadelphia agreed to return a statue of Frank Rizzo to the supporters that commissioned the memorial in 1992. The 2,000-pound bronze tribute to the former police commissioner-turned-mayor had stood in front of the city’s Municipal Services Building from 1998 until 2020, when then-mayor Jim Kenney ordered it removed days after protesters attempted to topple it during the protests that followed the murder of George Floyd.

Critiques of climate science, such as the report written for the Department of Energy by a panel in 2025, often point to this complexity to argue that these models are too uncertain to help us understand present-day warming or tell us anything useful about the future. But the history of climate science tells a different story.

Coal is the dirtiest source of fossil fuel energy and a major contributor of greenhouse gas emissions, making it bad not just for the climate but also for human health. That makes it a good target for cutting global emissions. A swift drop in coal use is the main reason U.S. greenhouse gas emissions fell in recent years as natural gas and renewable energy became cheaper.

social media has become a crucial outlet for young people to disclose abuse, connect with peers who’ve had similar experiences, and learn about safety strategies. In the midst of growing concerns about social media harming young people, its platforms offer important benefits for some vulnerable youth.

Versions of peer review have been around for centuries. But the modern form – anonymous, structured and managed by journal editors – took hold after World War II. Today, it is central to how scientific publishing works, and nowhere more so than health, nursing and medicine. Research that survives review is more likely to be trusted and acted upon by health care practitioners and their patients.

The largest tract of public land in the United States is a wild expanse of tundra and wetlands stretching across nearly 23 million acres of northern Alaska. It’s called the National Petroleum Reserve in Alaska, but despite its industrial-sounding name, the National Petroleum Reserve-Alaska, or NPR-A, is much more than a fuel depot. Tens of thousands of caribou feed and breed in this area, which is the size of Maine. Migratory birds flock to its lakes in summer, and fish rely on the many rivers that crisscross the region. It is about to get opened up to industrial exploitation.

Writing, reading, math and mindfulness? That last subject is increasingly joining the three classic courses, as more young students in the United States are practicing mindfulness, meaning focusing on paying attention to the present moment without judgment. Mindfulness programs vary in what particular mindfulness skills are taught and what lesson objectives are. This makes it difficult to compare across studies and draw conclusions about how mindfulness helps students in schools.

The Supplemental Nutrition Assistance Program has helped low-income Americans buy groceries for decades with few disruptions. A political scientist who has researched the history of government nutrition programs explains who SNAP helps, how enrollment varies from state to state and what the program costs to run.

Good coaching candidates are getting hired and doing their best to keep high school sports fixtures in their communities. But coaches often feel like they’re missing something, and they wonder whether they’re living up to those aspirations.

Former Vice President Dick Cheney was arguably the most powerful vice president in American history. He also thought that the assertive Congress of the 1970s had gone too far and had emasculated the presidency, making it nearly impossible for the president to get things done. Under Bush, he the unitary executive theory, a conservative thesis that calls for total presidential control over the entire executive branch. Now, nearly two decades later, President Donald Trump is using this theory to push his agenda.

Zohran Mamdani’s approach to democratic socialism is less about an abstract political ideology than it is about practical solutions. As he has put it: “We want to showcase our ideals, not by lecturing people about how correct we are, but rather by delivering and letting that delivery be the argument itself.” Because of this, he has also been described as an heir to the historical tradition of “sewer socialism”, a brand of left-wing thinking that favoured incremental, practical reform over revolutionary rhetoric.

For over a century, Hollywood has tended to portray Muslim men through a remarkably narrow lens: as terrorists, villains or dangerous outsiders. From shows such as “24” and “Homeland” to procedural dramas such as “Law and Order,” this portrayal has seldom allowed for complexity or relatability. Such depictions reinforce Orientalist stereotypes – a colonial worldview that treats cultures in the East as exotic, irrational or even dangerous.

Throughout the shutdown battle, Congress – particularly the House of Representatives – has been unwilling to assert itself as an equal branch of government. Beyond policymaking, Congress has been content to hand over many of its core constitutional powers to the executive branch. This renunciation of responsibility is difficult to watch. Yet Congress’ path to irrelevance as a body of government did not begin during the shutdown, or even in January 2025.

Thirty beluga whales are at the risk of being euthanized at the now-shuttered Marineland zoo and amusement park in Niagara Falls, Canada. Marineland said in a letter to Canada’s Fisheries Minister Joanne Thompson it will have to euthanize the whales if it doesn’t receive the necessary financial support to relocate them. The park has come under intense scrutiny recently due to the ongoing struggle to relocate its remaining whales amid financial struggles, a lack of resources and crumbling infrastructure.

The Trump administration announced plans to stop releasing food insecurity data. The federal government has tracked and analyzed this data for the past three decades. Food banks relied on the data to understand who was most likely to need their help. The data also allowed policymakers to see the big jump in need during the Great Recession starting in 2008. It also showed a slight decline in food insecurity with the rise in government assistance early in the COVID-19 pandemic.

A new study of 600 employees suggests burnout may quietly fuel worrying attitudes – specifically, the potential justification of violent extremism – towards the perceived source of their distress. In the study, employees made daily notes of their burnout symptoms, emotional states, and violent extremist attitudes. On days when employees felt more burnt out, they reported significantly more sympathy toward extremist ideas, such as justifying violence against perceived injustices.

the Trump administration is mobilizing heritage and architecture as tools of ideology and control. He is seeking to roll back inclusive historical narratives at U.S. parks and monuments. And he is reviving sanitized myths about America’s history of slavery, misogyny and Manifest Destiny, for use in museums, textbooks and public schools. Dictators, tyrants and kings build monumental architecture to buttress their own egos, which is called authoritarian monumentalism. They also seek to build the national ego – another word for nationalism.

Mark Twain would have found Trump the showman – the pre-2016 version – a fascinating figure. He would have been appalled, however, by much about Trump the president. Imagining how Twain would view Trump is timely because when some have tried to look to history for an equivalent political moment, they’ll sometimes point to two decades – the 1880s and the 1900s – that happened to also be important in Twain’s life and career.

Shockoe Hill African Burying Ground, the largest burial ground for enslaved and free people of color in the United States, has witnessed deliberate acts of violence. As the historian Ryan K. Smith writes, Shockoe “was not, as some would say, abandoned – it was actively destroyed.” In recent years, similar threats to Black cemeteries and questions about preservation have been reported at the Whitney Plantation in Louisiana, the Morningstar Tabernacle No. 88 in Maryland and a rediscovered graveyard in Florida, among many others.

On Sunday October 19, criminals managed to steal eight pieces of extremely valuable jewelry from the Louvre Museum’s Gallery of Apollo, in Paris. The robbery highlights long-standing issues for criminology in the field of cultural heritage, as museum security has to address traditional and emerging threats as well as a range of symbolic visions and criminal dynamics. From a security point of view, there are five key ideas that can help us understand what the flaws were in the Louvre, as well as how, and why, criminals target museums.

The spectacle of a Spanish-speaking rapper performing during the most-watched sporting event on American TV is a direct rebuke of the Trump administration’s efforts to paper over the country’s diversity. Beyond that, there’s his gender-bending wardrobe. He has slammed the Trump administration’s anti-immigration policies. He has declined to tour on the U.S. mainland, fearing that some of his fans could be targeted and deported by ICE. And his explicit lyrics – most of which are in Spanish – would make even the most ardent free speech warrior cringe.
