Phys.org / Failed experiment leads to surprise drug development breakthrough
Scientists at the University of Cambridge have developed a new way to alter complex drug molecules using light rather than toxic chemicals—a discovery that could accelerate and improve how medicines are designed and made. ...
Phys.org / Gut microbes: The secret to squirrel hibernation
When winter sets in and food becomes scarce, some mammals hibernate, entering a state of deep rest that slashes their energy needs and allows them to fast for months. However, fasting deprives them of essential nutrients, ...
Phys.org / Fortified salad packs a healthy punch to meet a growing vitamin B12 need
A pioneering research-industry partnership has used advances in indoor farming technology to grow pea shoots fortified with vitamin B12, opening an exciting route to market for farmers and addressing a major public health ...
Phys.org / Meet Crocodylus lucivenator, a 12- to 15-foot predator that hunted iconic Lucy's species
More than 3 million years ago, when our ancient ancestors embodied by the iconic Lucy were roaming the African landscape, they would have feared a big, bad crocodile with a prominent lump on its head, patiently lurking in ...
Phys.org / Caught but not eaten: Smaller insects more likely to escape catfish mouths
A Kobe University study shows that small aquatic beetles survive catfish attacks by resisting ingestion inside the catfish's mouth and being spat out alive. This research contributes to a deeper understanding of size-dependent ...
Phys.org / Despite their contrasting reputations, bonobos and chimpanzees show similar levels of aggression in zoos
Chimpanzees have a reputation for being aggressive, while bonobos are often seen as their peaceful counterparts. This contrast has frequently been used to explain different sides of human nature. However, a new study by Utrecht ...
Phys.org / Dolphin mass strandings in Patagonia linked to killer whales
In 2021 and 2023, hundreds of dolphins were stranded in shallow waters in San Antonio Bay in northern Patagonia. Some died, but many were returned safely to the sea. But what remained a mystery until now was how they ended ...
Phys.org / Galaxy-group motion suggests slower expansion in our cosmic neighborhood
Two new studies have measured the expansion of the universe in our immediate cosmic neighborhood using a novel method that analyzes the motion of two nearby galaxy groups within their surrounding cosmic flow. The results ...
Phys.org / Astronomers collect rare evidence of two planets colliding
Anastasios (Andy) Tzanidakis was combing through old telescope data from 2020 when he found an otherwise boring star acting very strangely. The star, named Gaia20ehk, was about 11,000 light-years from Earth near the constellation ...
Phys.org / DNA origami vaccine rivals mRNA shots while being easier to store and manufacture
The COVID-19 pandemic brought messenger RNA (mRNA) vaccines to the forefront of global health care. After their clinical trial stages, the first COVID-19 mRNA vaccine was administered on 8 December 2020 and mathematical models ...
Phys.org / Centuries of net-negative emissions are required to secure a safe climate future, two studies suggest
Two new studies conclude that stabilizing long-term climate risks will require sustained net-negative carbon dioxide (CO₂) emissions for centuries. Approaching the problem from distinct perspectives—legal and technological ...
Phys.org / Plants pause, play and fast-forward their growth depending on types of climate stress
Plants pause their growth during stress, then press play when conditions improve, helping them recover and live on to produce food, according to a new study published in New Phytologist. UBC researchers have pinpointed the ...
