After a year and a half of remote work and learning, UC Santa Barbara undergraduate students Sophia Lecuona Manos, Gabrielle Plewe, Carson Gadler and doctoral student Zoe Zilz returned to campus in late 2021 eager for some on-campus, hands-on research, an opportunity that was
Turning waste into wealth may no longer be just a marketing slogan, as a team of researchers in China has found an eco-friendly way to do exactly that. The abundant sunlight our planet receives was put to use for transforming polystyrene waste, one of the world's largest
There’s no bulletproof remedy for a hangover, but a nutrition scientist explains which foods could aid symptoms after one has had too much to drink
A key Alzheimer’s drug has finally revealed its secret. Researchers discovered that lecanemab works by activating the brain’s immune cells—but only through a specific part of the antibody called the Fc fragment. This piece acts like a trigger, prompting microglia to clear
Over the past decades, electronics engineers have been trying to develop increasingly smaller devices that can store information reliably, even when they are not powered on. A promising type of non-volatile memory device is spintronics, solid-state systems that store and
A mysterious metal-rich asteroid called Psyche has been baffling scientists for over two centuries, and its true origin remains one of the biggest unanswered questions in planetary science. Is it the exposed core of a failed planet, or a chaotic mix of rock and metal forged
Even 200 years after asteroid 16 Psyche was discovered, astronomers continue to puzzle over its formation. Psyche is the 10th-most massive asteroid in the main belt between Mars and Jupiter, and the largest known metallic asteroid, at 140 miles in diameter.
A growing field of research suggests that some medical treatments, such as cancer therapy or vaccines, might be more effective when given at certain times of the day

It wasn’t Saint Patrick but a long history of chilly weather and geographic isolation that kept the Emerald Isle snake-free
The most common side effects of mRNA vaccines like the COVID-19 shot are well known: soreness, mild fever, and general malaise. Those symptoms, which typically resolve within days, are the natural result of the immune system activating. But what if they could be avoided?
Chronic kidney disease has a variety of causes, ranging from immune system problems to medication side effects

Physicists working on the LHCb experiment have spotted an elusive and fleeting particle, a heavier and more charming cousin to the proton, that has been sought for decades
A new study reveals an unprecedented increase in wildfires in tropical peatlands during the 20th century. "Unprecedented burning in tropical peatlands during the 20th century compared to the previous two millennia" is published in Global Change Biology.
The levels of a heavy form of hydrogen in 3I/ATLAS are 30 to 40 times higher than in Earth's oceans, suggesting the comet has a cold and distant origin
Researchers have identified a surprising brain pattern that may help explain why people with ADHD often struggle to stay focused. Even while awake, their brains can slip into brief episodes of “sleep-like” activity during demanding tasks. These moments are linked to more
The James Webb Space Telescope has revealed new details in a bizarre nebula that looks like a brain floating in space. Formed by a dying star, the “Exposed Cranium” nebula shows layered gas and a dark central divide that creates its eerie shape. Webb’s infrared view suggests
mRNA vaccines saved millions of lives during COVID-19 but have limitations like waning immunity and complex production. Scientists are now testing a new platform called DoriVac, which uses folded DNA nanostructures to better control how the immune system responds. In early
What do we really know about how oviraptors—bird-like but flightless dinosaurs—hatched their eggs? Did they use environmental heat, like crocodiles, or body heat from an adult, like birds? In a new Frontiers in Ecology and Evolution study, researchers in Taiwan examined the
