Phys.org / These nanotweezers grab thousands of tiny cell packets in seconds and expose their hidden cargo
Justus Ndukaife, associate professor of electrical and computer engineering and Chancellor Faculty Fellow, and his team have developed next generation nanotweezers that better analyze extracellular vesicles and aid in unraveling ...
Phys.org / Small talk surprises: Nine experiments show 'boring' topics feel more enjoyable
The small talk you try to avoid because you think it will be boring may actually be more enjoyable than you think, and good for you as well, according to research published in the Journal of Personality and Social Psychology.
Phys.org / Future-proofing livestock vaccines by anticipating viruses' next moves
The wave-shaped chart Ratul Chowdhury pulls up on a computer monitor in his office captures the evolutionary cat-and-mouse game his research lab is up against. The undulating curves track variants of the porcine reproductive ...
Phys.org / Gold nanorod makes spinning light when struck off-center by an electron beam
Light, as we usually conceive of it, is defined by the astonishing velocity at which it moves from one point to another. For example, in just one second, light can travel most of the distance between Earth and the moon. This ...
Phys.org / Painkillers prevent pain responses in Norway lobsters, intensifying the case against boiling them alive
Common human painkillers also work on Norway lobsters, according to research from the University of Gothenburg. This is further evidence that crustaceans may feel pain and that more humane methods of killing them need to ...
Phys.org / Of gray whales that enter San Francisco Bay, nearly 18% die there, scientists find
Gray whales migrate from Arctic waters full of food to the lagoons of Baja Mexico—but as the climate crisis gathers pace, they have been sighted foraging in unexpected places. Recently, some have begun to explore the dangerously ...
Phys.org / Nanodiscs capture HIV and Ebola surface proteins in lifelike membranes for vaccine design
Viruses are masters at invading cells thanks to specialized proteins that coat their surfaces. When scientists design vaccines, they often create versions of these viral surface proteins to study how the immune system might ...
Phys.org / Cacti fungal endophytes may help cacao tolerate drought
Beans of the cacao plant, Theobroma cacao, are used in chocolates, pharmaceuticals and other products, but they're under threat. Increased drought associated with climate change has already begun to stress cacao-growing regions ...
Phys.org / Astronomers find the strongest evidence yet for the universe's first stars
For decades, astronomers were only able to study the universe's very first stars using theoretical models. Now, observations from the James Webb Space Telescope (JWST) have revealed what may be the most compelling evidence ...
Phys.org / Extinct ice age giants in Bender's Cave challenge existing climate records for the Edwards Plateau
A recent study by Dr. John Moretti of the University of Texas and local caver John Young uncovered the remains of Ice Age megafauna, revealing an entirely new ecosystem that once thrived on the Edwards Plateau. Among the ...
Phys.org / Ancient Korean DNA reveals marriages between closely related individuals
DNA studies of 1,500-year-old skeletons have revealed that ancient Koreans lived in tightly knit family networks where marrying close relatives was common in some cases, from powerful elites to individuals chosen for human ...
Phys.org / Space telescopes track nearby quasar's dramatic X-ray state transition
By analyzing the data from various space observatories, Chinese astronomers have inspected a nearby quasar designated SDSS J000532.84+200717.4. Results of the new study, published April 1 on the arXiv preprint server, shed ...
