43 Million Children Forced From Homes Over Six Years Due to Climate Disasters

The U.N.'s children's welfare agency released a new report Friday making the case for prioritizing the protection of children from fossil fuel-driven climate disasters—with more than 43 million children across the globe internally displaced in a six-year period due to drought, flooding, wildfires, and other extreme events.

In the report Children Displaced in a Changing Climate, United Nations Children's Fund (UNICEF) details how 95% of child displacements in 44 countries from 2016-21 were due to flooding and storms, with 40.9 million children forced from their homes in countries including Guatemala, South Sudan, and Somalia.

Quantum dots are part of a revolution in engineering atoms in useful ways – Nobel Prize for chemistry recognizes the power of nanotechnology

The 2023 Nobel Prize for chemistry isn’t the first Nobel awarded for research in nanotechnology. But it is perhaps the most colorful application of the technology to be associated with the accolade.

This year’s prize recognizes Moungi Bawendi, Louis Brus and Alexei Ekimov for the discovery and development of quantum dots. For many years, these precisely constructed nanometer-sized particles – just a few hundred thousandths the width of a human hair in diameter – were the darlings of nanotechnology pitches and presentations. As a researcher and adviser on nanotechnology, I’ve even used them myself when talking with developers, policymakers, advocacy groups and others about the promise and perils of the technology.

How a disgruntled scientist looking to prove his food wasn’t fresh discovered radioactive tracers and won a Nobel Prize 80 years ago

Each October, the Nobel Prizes celebrate a handful of groundbreaking scientific achievements. And while many of the awarded discoveries revolutionize the field of science, some originate in unconventional places. For George de Hevesy, the 1943 Nobel Laureate in chemistry who discovered radioactive tracers, that place was a boarding house cafeteria in Manchester, U.K., in 1911.

Popular weight loss drugs linked to higher risk of stomach paralysis

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.

Intel officer begged Pentagon to release UFO details — but it refused: new documentary

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 more than two metres in two years

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.

What is an attosecond? A physical chemist explains the tiny time scale behind Nobel Prize-winning research

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.

Cell death is essential to your health − an immunologist explains when cells decide to die with a bang or take their quiet leave

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.

September hottest on record by 'extraordinary' margin, says EU monitor

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.

Impersonator conjures Charles Darwin on Galapagos visit

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.

Nobel chemistry winner flunked first college chemistry exam

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.

SpaceX aims for its 50th Space Coast launch this year

SpaceX is targeting its 50th Space Coast launch of the year with another Starlink mission from Cape Canaveral Space Force Station. A Falcon 9 carrying 22 of the company’s Starlink satellites is slated for liftoff from Canaveral’s Space Launch Complex 40 at 10:45 p.m. with four backup opportunities from 11:38 p.m. until 1:57 a.m. overnight and six backup opportunities late Thursday from 10:29 p.m. until 1:49 a.m. early Friday. Space Launch Delta 45’s weather squadron forecasts a 50% chance for good conditions with 70% chance in event of a 24-hour delay. The booster on this flight is making its ...

Nobel Prize in chemistry goes to U.S.-based trio for work on tiny quantum dots

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.
