Drugs like Ozempic, which have become increasingly popular for losing weight, heighten the risk of certain severe gastrointestinal problems including stomach paralysis, according to a large study published Thursday.

The paper, published in the Journal of the American Medical Association (JAMA), looked at a class of drugs called GLP-1 agonists that includes the brands Wegovy, Ozempic, Rybelsus and Saxenda.

Former President Barack Obama once joked in an interview that the question he gets asked the most about his time in the White House is what he learned about UFOs or aliens. Under President Joe Biden's administration, the Pentagon appears to be running the show.

The July 25 hearing with former intelligence officer David Grusch revealed that the U.S. government is allegedly handling extraterrestrial technology – and it's keeping it close to the vest. The Washington Post told the story of the whistleblower driving to the Capitol and begging the Pentagon's security office to clear more information for the public to access.

France's tallest mountain Mont Blanc has shrunk by over two meters in height over the past two years, researchers said Thursday, measuring the Alpine peak at 4,805.59 meters (15,766.4 feet).

The 2.22-meter (7.28 feet) decline could be down to lower precipitation during summer, said Jean des Garets, chief geometer in the Haute-Savoie department of southeastern France.

A group of three researchers earned the 2023 Nobel Prize in physics for work that has revolutionized how scientists study the electron – by illuminating molecules with attosecond-long flashes of light. But how long is an attosecond, and what can these infinitesimally short pulses tell researchers about the nature of matter?

I first learned of this area of research as a graduate student in physical chemistry. My doctoral adviser’s group had a project dedicated to studying chemical reactions with attosecond pulses. Before understanding why attosecond research resulted in the most prestigious award in the sciences, it helps to understand what an attosecond pulse of light is.

Living cells work better than dying cells, right? However, this is not always the case: your cells often sacrifice themselves to keep you healthy. The unsung hero of life is death.

While death may seem passive, an unfortunate ending that just “happens,” the death of your cells is often extremely purposeful and strategic. The intricate details of how and why cells die can have significant effects on your overall health.

Last month was the hottest September on record by an "extraordinary" margin as the world flirts dangerously with breaching a key warming limit, the EU climate monitor said on Thursday.

Much of the world sweltered through unseasonably warm weather in September, in a year expected to be the hottest in human history and after the warmest-ever global temperatures during the Northern Hemisphere summer.

With a long grey beard and old-school brown suit, a Charles Darwin lookalike observes marine iguanas and the blue-footed booby - an iconic bird on the Galapagos Islands.

Two centuries after the British biologist visited the archipelago which inspired his theory of evolution, a retired US professor has tracked part of his journey all while dressed as his 19th-century hero.

Talk about bouncing back.

MIT professor Moungi Bawendi is a co-winner of this year's Nobel chemistry prize for helping develop "quantum dots" -- nanoparticles that are now found in next generation TV screens and help illuminate tumors within the body.

Three scientists won the Nobel Prize in chemistry for their work on tiny quantum dots.

Moungi Bawendi, of MIT, Louis Brus, of Columbia University, and Alexei Ekimov, of Nanocrystals Technology Inc., were honored for their work with the tiny particles that are just a few atoms in diameter and whose electrons have constrained movement. This effects how they absorb and release visible light, allowing for very bright colors. They are used in many electronics, like LED displays.

There never used to be young great white sharks basking off the busy beaches of central California, but as climate change starts to bite, warmer waters are enticing them north -- with possibly catastrophic consequences for a whole ecosystem.

Despite their fearsome reputation, brought about in part by the "Jaws" movie franchise, the main risk from these predators is not to swimmers and surfers -- or even the local police chief -- but to otters.

To hunt the narwhal, whose long tusk was the unicorn horn of medieval myth, you need absolute silence.

So much so that the Indigenous hunters of the Scoresby Sound in eastern Greenland forbid their children from throwing pebbles into the water lest they spook the spiral-tusked whales.

Shifting weather patterns caused by climate change are limiting when controlled burns can be carried out to prevent wildfires in the western United States, a new study warns.

Controlled burns, also known as prescribed fires, are a tool to preemptively dispose of combustible vegetation with the goal of preventing larger, uncontrolled fires.
