The opioid crisis remains a significant public health challenge in the United States. In 2022, over 2.5 million American adults had an opioid use disorder, and opioids accounted for nearly 76% of overdose deaths.

Some patients are fearful of using opioids after surgery due to concerns about dependence and potential side effects, even when appropriately prescribed by a doctor to manage pain. Surgery is often the first time patients receive an opioid prescription, and their widespread use raises concerns about patients becoming long-term users. Leftover pills from a patient’s prescriptions may also be misused.

A scientist guides a long tube into the mouth and down to the stomach of Thing 1, a two-month-old calf that is part of a research project aiming to prevent cows from burping methane, a potent greenhouse gas.

"Planet of the Apes" may have been onto something.

Chimpanzees are steadily honing their tool-using skills -- a process unfolding over millennia, driven by the exchange of ideas through migrations between populations, according to a new study published Thursday in Science.

A group of chemical compounds used to disinfect water for one-third of the US population and millions of others globally produces a potentially toxic byproduct, according to new research published Thursday, sparking calls for an "immediate" investigation into possible health impacts.

Inorganic chloramines have been used for decades to remove pathogens from public water supplies.

Plastic pollution litters our seas, our air and even our bodies, but negotiators face an uphill battle next week to agree on the world's first treaty aimed at ending the problem.

Countries will have a week in South Korea's Busan from Monday to round off two years of negotiations.

Scientists said Thursday they have taken the first ever close-up image of a star outside of the Milky Way, capturing a blurry shot of a dying behemoth 2,000 times bigger than the Sun.

Roughly 160,000 light years from Earth, the star WOH G64 sits in the Large Magellanic Cloud, a satellite galaxy of our home Milky Way.

Physicists have long grappled with the question of why the universe was able to support the evolution of intelligent life. The values of the many forces and particles, represented by some 30 so-called fundamental constants, all seem to line up perfectly to enable it.

Take gravity. If it were much weaker, matter would struggle to clump together to form stars, planets and living beings. And if it were stronger, that would also create problems. Why are we so lucky?

The normally straight-faced CNN host Jake Tapper couldn't hold back his skepticism after airing a newly unearthed video of Robert F. Kennedy Jr. suggesting the U.S. government secretly orchestrated the COVID-19 pandemic.

The video, revealed by The Bulwark on Tuesday, shows Kennedy — President-elect Donald Trump's choice to head the Department of Health and Human Services — talking about the pandemic, and that "a lot of it feels very planned to me."

A little-noticed change to South Africa’s national health research guidelines, published in May of this year, has put the country on an ethical precipice. The newly added language appears to position the country as the first to explicitly permit the use of genome editing to create genetically modified children.

Heritable human genome editing has long been hotly contested, in large part because of its societal and eugenic implications. As experts on the global policy landscape who have observed the high stakes and ongoing controversies over this technology — one from an academic standpoint (Françoise Baylis) and one from public interest advocacy (Katie Hasson) — we find it surprising that South Africa plans to facilitate this type of research.

Rep. Jared Moskowitz (D-FL) slammed Rep. Marjorie Taylor Greene's (R-GA) conspiracy theory that Jewish space lasers ignited forest fires in California.

During a House Oversight Committee hearing Thursday, Moskowitz said he agreed with the decision to dismiss an employee of the Federal Emergency Management Agency, or FEMA, after she suggested that homes displaying support for President-elect Donald Trump should be avoided while providing hurricane relief.

Beliefs are convictions of reality that we accept as true. They provide us with the basic mental scaffolding to understand and engage meaningfully in our world. Beliefs remain fundamental to our behavior and identity, but are not well understood.

Delusions, on the other hand, are fixed, usually false, beliefs that are strongly held, but not widely shared. In previous work, we proposed that studying delusions provides unique insights into the cognitive nature of belief and its dysfunction.

Once every spring, a few days after the full moon, corals of the great barrier reef release eggs and sperm simultaneously – a phenomenon so spectacular it can be seen from space.

Not only does the Moon’s gravitational attraction interact with the Sun to cause our tides (ebb and flow), its orbit around Earth generates different Moon phases of varying luminosity. Scientists think the Moon’s light at a certain point each spring may provide a cue to corals that the conditions are right to release eggs and sperm.

Parts of the Great Barrer Reef have suffered the highest coral mortality on record, Australian research showed Tuesday, with scientists fearing the rest of it has suffered a similar fate.

The Australian Institute of Marine Science said surveys of 12 reefs found up to 72 percent coral mortality, thanks to a summer of mass bleaching, two cyclones, and flooding.
