Tree pollen carries SARS-CoV-2 particles farther, facilitates virus spread
Most models explaining how viruses are transmitted focus on viral particles escaping one person to infect a nearby person. A study on the role of microscopic particles in how viruses are transmitted suggests pollen is nothing to sneeze at......»»
Locked in a glacier: Virus adaptations to extreme weather provide climate change insights
Ancient viruses preserved in glacial ice hold valuable information about changes in Earth's climate, a new study suggests......»»
On wildfires, experts say the West needs to rethink its response
Wildfires and the pain they cause to people, property and the planet are here to stay. And if Western management practices don't change to anticipate more and more record fire years, that pain may spread and worsen......»»
Heaviest antimatter observation yet will fine-tune numbers for dark matter search
In experiments at the Brookhaven National Lab in the US, an international team of physicists has detected the heaviest "anti-nuclei" ever seen. The tiny, short-lived objects are composed of exotic antimatter particles......»»
Aoudad and bighorn sheep share respiratory pathogens, research team discovers
A team of researchers at the Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) has discovered that aoudad—an animal in the sheep and goat family—can catch and spread many of the same respiratory pathogens that can impact des.....»»
Ultra-sensitive photothermal microscopy technique detects single nanoparticles as small as 5 nm
The detection of individual particles and molecules has opened new horizons in analytical chemistry, cellular imaging, nanomaterials, and biomedical diagnostics. Traditional single-molecule detection methods rely heavily on fluorescence techniques, w.....»»
Scientists discover novel receptor recognition mechanism for alphavirus
Eastern Equine Encephalitis virus (EEEV), an alphavirus, can cause central nervous system infections that can lead to severe encephalitis with a mortality rate of over 30%......»»
Breaking boundaries: The unexpected routes of minerals in crop growth
Imagine plants not just sipping nutrients dissolved in water, but actually munching on tiny mineral particles straight from the soil. A study sheds light on how wheat and lettuce aren't just passive feeders—they actively grab, transport, and utiliz.....»»
How particles of light may be producing drops of the perfect liquid
The world's largest and most powerful particle accelerator may be producing the world's tiniest droplets of liquid, right under scientists' noses. Researchers are digging into this subatomic enigma......»»
Town urges curfew over mosquito-spread disease that kills up to 50% of people

Novel carbon nanohorn-based treatment enables efficient delivery of drugs in cancer therapy
Cancer remains one of the most challenging diseases to treat due to its complexity and tendency to metastasize (spread into, or invade, nearby tissues or distant places in the body to form new tumors). Traditional therapies, such as chemotherapy and.....»»
Deviations in particle interactions point to the existence of new bosons
Professors Andreas Crivellin of the University of Zurich and Bruce Mellado of the University of the Witwatersrand and iThemba LABS in South Africa have documented deviations in the way particles interact. These deviations are inconsistent in comparis.....»»
Physicists observe key minuscule molecular interactions in ultra-fast atomic processes
An international team of scientists is the first to report incredibly small time delays in a molecule's electron activity when the particles are exposed to X-rays......»»
Killing giant ragweed just got harder for some Wisconsin farmers
When giant ragweed takes hold in a crop field, the towering weed reduces yield and sends plumes of its famously allergy-inducing pollen into the air. There are few tools available to thwart the menace, especially for farmers growing non-GMO soybeans......»»
Ancient microbes linked to evolution of human immune proteins
When you become infected with a virus, some of the first weapons your body deploys to fight it are those passed down to us from our microbial ancestors billions of years ago. According to new research from The University of Texas at Austin, two key e.....»»
Honey bees may play key role in spreading viruses to wild bumble bees
Honey bees may play a role in increasing virus levels in wild bumble bees each spring, according to researchers at Penn State who analyzed seasonal trends of parasite and virus transmission in bees......»»
New data on radiation show missions to Jupiter"s moon Europa are possible
Scientists from NASA's Juno mission have developed the first complete 3D radiation map of the Jupiter system, including characterizing the intensity of the high-energy particles near the orbit of the icy moon Europa, and how the radiation environment.....»»
Physicists develop new model that describes how filaments assemble into active foams
Many fundamental processes of life, and their synthetic counterparts in nanotechnology, are based on the autonomous assembly of individual particles into complex patterns. LMU physicist Professor Erwin Frey, Chair of Statistical and Biological Physic.....»»
Environmental laws failing to slow deforestation, researchers say
Australia's environmental laws are failing to stop high rates of tree clearing to make way for agriculture, development and mining, according to University of Queensland research......»»
Ancient tree resin artifacts provide earliest-known evidence of humans dispersing through the Pacific
Exactly when and how humans dispersed into and through the Pacific remains an intensely debated topic. Previous studies have been hampered by imprecise chronometric dating, making the exact timing and movement of people into the Pacific difficult to.....»»
This year’s summer COVID wave is big; FDA may green-light COVID shots early
Wastewater SARS-CoV-2 levels suggest the summer surge is high and peaking right now. Enlarge (credit: Getty | Thomas Trutschel) With the country experiencing a relatively large summer wave of COVID-19, the Food and Drug.....»»
