'Voracious' giant snails spark alarm in Venezuela
On the hunt for the methane "super-emitters", US President Joe Biden on Friday unveiled a plan to plug oil and gas leaks and tighten regulation as several global emitters vowed to step up efforts to slash pollution of the powerful greenhouse gas.
Advances in spectroscopy: Physicists find new way to measure properties of a material's surface layer
A "plague" of giant African snails that pose potential health risks to humans is causing alarm in Venezuela where sustained rains have facilitated their proliferation.
Booming trade in mammoth ivory may be bad news for elephants
Physicists at The University of Texas at Arlington have developed a new technique that can measure the properties of the topmost atomic layer of materials without including information from the underlying layers.

Probiotic 'backpacks' show promise for treating inflammatory bowel diseases
In 2015, Andy Huynh was accompanying wildlife guards in Kenya’s Maasai Mara National Reserve to help ward off poachers. Fresh off a decade of service in the Middle East with U.S. Special Operations Forces, he thought there was little that could faze him. But when he saw his first poached rhinoceros, with half of its face sawed away for the horn, he turned and...

Rats bop to the beat
A new study demonstrates just how much promise modified probiotic bacteria hold for improving inflammatory bowel disease (IBD) treatments, including for Crohn's disease and ulcerative colitis.

Physicists find new way to measure properties of a material's surface layer
Accurately moving to a musical beat was thought to be a skill innately unique to humans. However, new research now shows that rats also have this ability. The optimal tempo for nodding along was found to depend on the time constant in the brain (the speed at which our brains can respond to something) which is similar across all species. This means that the ability of our auditory and motor systems...

Popular dietary supplement causes cancer risk, brain metastasis
Physicists have developed a new technique that can measure the properties of the topmost atomic layer of materials without including information from the underlying layers.

Divers Discover a Long-Lost Piece of the Shuttle Challenger
While previous studies have linked commercial dietary supplements like nicotinamide riboside (NR), a form of vitamin B3, to benefits related to cardiovascular, metabolic and neurological health, new research has found NR could actually increase the risk of serious disease, including developing cancer. The international team of researchers discovered high levels of NR could not only increase...
NASA’s Mega-Moon Rocket Survives a Hurricane
It was more than 36 years ago that NASA suffered one of its greatest tragedies, when the space shuttle Challenger exploded 73 seconds after liftoff on a cold January morning in 1986. Yesterday, NASA reported that a piece of debris from Challenger was found off the coast of Florida by a team of divers who were filming a documentary on the loss of World War II era aircraft in the same area....
Slaves to the rhythm: rats can’t resist a good beat, researchers say
If you owned a 32-story, 2.6 million kg (5.7 million lb), $4.1 billion moon rocket, the last thing you’d think you’d want to do is leave it out in a hurricane. Well, NASA does own a 32-story, 2.6 million kg, $4.1 billion moon rocket and leaving it out in a hurricane is just what the agency did yesterday—mostly because that turned out to be the best and safest of a bad lot of...
Rats bopping to the beat in video demonstrate innate beat synchronization in animals for the first time
Study finds rats instinctively move in time to music – an ability previously thought to be uniquely humanMusic makes you lose control, Missy Elliott once sang on a hit that is almost impossible to hear without bopping along. Now scientists have discovered that rats also find rhythmic beats irresistible, showing how they instinctively move in time to music.This ability was previously thought to...
How racism skewed estimates of heart disease in women
Accurately moving to a musical beat was thought to be a skill innately unique to humans. However, new research now shows that rats also have this ability. The optimal tempo for nodding along was found to depend on the time constant in the brain (the speed at which our brains can respond to something), which is similar across all species.

Young people identify 7 'superpowers' to fight climate change
Growing up as a multiracial person in the United States, Alexis Reeves was no stranger to the impact of racial discrimination. She spent summer vacations with her father’s family in Pennsylvania, where her Black grandfather had worked as a sharecropper. Nearly everyone on that side of her family had high blood pressure, took cholesterol medication, or had experienced some form of heart...
Physicist probes causes of life-shortening 'dwell fatigue' in titanium
Many young people feel anxious, powerless, sad and angry about climate change.
'Climate activism is everywhere, and not just on the streets,' claim authors of new book
"Dwell fatigue" is a phenomenon that can occur in titanium alloys when held under stress, such as a jet engine's fan disc during takeoff. This peculiar failure mode can initiate microscopic cracks that drastically reduce a component's lifetime.
Researchers optimize thermoelectric properties of lead telluride material systems
A new book documents the "transformation" of climate activism, arguing it has gone beyond the streets to exist in new and unexpected forms.
'Toxic cover-up': 6 lessons Australia can draw from the UN's scathing report on greenwashing
In a recent study, a research team from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences achieved higher thermoelectric performance of n-type lead telluride (PbTe) by adjusting the band structure and enhancing phonon scattering. Results were published in Nanoscale.
The mathematics that makes us realize we don't know much: Behavior of spin glasses
The United Nations this week slammed corporate "greenwashing" and said organizations cannot claim to be net-zero while supporting fossil fuel projects.
In search of the perfect match schedule
Spin glasses are alloys formed by noble metals in which a small amount of iron is dissolved. Although they do not exist in nature and have few applications, they have nevertheless been the focus of interest of statistical physicists for some 50 years. Studies of spin glasses were crucial for Giorgio Parisi's 2021 Nobel Prize in Physics.
Sports and competition are inextricably linked. But producing the optimal match schedule is a sport in itself. Mathematician Roel Lambers studied ways to ensure that darts players and teams playing either soccer or a Dutch regional sport called beugelen are matched up as fairly as possible. He defended his thesis on Friday November 11th at the Department of Mathematics and Computer Science.
