The Quantum Geometry That Exists Outside of Space and Time
A decade after the discovery of the “amplituhedron,” physicists have excavated more of the timeless geometry underlying the standard picture of how particles move......»»
Ancient mud reveals Australia"s burning history over the past 130,000 years—and a way forward in current fire crisis
Increased land management by Aboriginal people in southeastern Australia around 6,000 years ago cut forest shrub cover in half, according to our new study published in Science of fossil pollen trapped in ancient mud......»»
How and why people spread rumors is key to understanding how false information travels and takes root
On Sept. 20, 2024, a newspaper in Montana reported an issue with ballots provided to overseas voters registered in the state: Kamala Harris was not on the ballot. Election officials were able to quickly remedy the problem, but not before accusations.....»»
H5N1 Detected in Pig Highlights the Risk of Bird Flu Mixing with Seasonal Flu
Humans and pigs could both serve as mixing vessels for a bird flu–seasonal flu hybrid, posing a risk of wider spread.....»»
Bats use echolocation to make mental maps for navigation
Despite only working over short distances, echolocation is enough to get bats home. Many species of bats use echolocation to avoid obstacles like tree branches and hunt small inse.....»»
Advances in taro research: New gene silencing system enables rapid gene function verification
A research team has established a virus-induced gene silencing (VIGS) system in taro, enabling researchers to rapidly verify gene functions in this underutilized crop. Utilizing a tobacco rattle virus (TRV)-based vector, the study paves the way for s.....»»
Charcoal stored in preserved guano gives helps reconstruct regional fire histories
With wildfires growing more frequent and more intense in many parts of the world, scientists are looking to the past to better understand where and when fires have burned. Lakes and wetlands, which capture airborne charcoal particles when they fall f.....»»
Destructive weed, found in New York state, resists common herbicides
The invasive pigweed Palmer amaranth, first found in New York soybean fields in 2019, has been dubbed the "spotted lanternfly of weeds" for its ability to spread quickly and wreak havoc on crops. Now a new study sheds light on how formidable an oppon.....»»
One in Three Tree Species Is at Risk of Extinction
A review of 47,282 tree species by the International Union for Conservation of Nature found that more than one third are at risk of extinction.....»»
Researchers observe stick-slip phenomenon in carbon nanotube fibers
The shapes of simple polyatomic molecules such as carbon dioxide and methane are characterized by a specific symmetry depending on the manner of linking of the atoms. Nano- to micrometer-sized particles that mimic the shapes of such polyatomic molecu.....»»
Astrophysicists measure "dance" of electrons in the glow from exploding neutron stars
The temperature of elementary particles has been observed in the radioactive glow following the collision of two neutron stars and the birth of a black hole. This has, for the first time, made it possible to measure the microscopic, physical properti.....»»
A Bird Flu Vaccine Might Come Too Late to Save Us from H5N1
If the influenza virus infecting cattle workers starts a pandemic, help in the form of a vaccine is months away.....»»
Researchers show nanoplastics can reduce the effectiveness of antibiotics
In a recent study, an international research team with significant involvement from MedUni Vienna has investigated how nanoplastic particles deposited in the body affect the effectiveness of antibiotics......»»
New image recognition technique for counting particles provides diffusion information
A team of scientists have invented a new technique to determine the dynamics of microscopic interacting particles by using image recognition to count the number of particles in an imaginary box. By changing the size of the observation box, such count.....»»
Expert explains how misinformation thrives on emotional triggers—and why traditional fact-checking often misses the mark
A recent Gallup poll showed public trust in the electoral process—a cornerstone of American democracy—is eroding as the rampant spread of misinformation and organized disinformation campaigns breed dangerous skepticism among voters. Now, with ear.....»»
