Phys.org / Engineered enzymes forge carbon-carbon and carbon-nitrogen bonds with high selectivity
Researchers from the Manchester Institute of Biotechnology, including Dr. Zachary Birch-Price and professor Anthony Green, have developed a new family of engineered enzymes that can create several different types of chemical ...
Medical Xpress / Two-stage process helps metastatic cancer cells hide, then multiply in the lungs
Most cancer deaths are caused not by the initial tumor but by the spread of cancer cells to distant organs in the process called metastasis. Since it occurs at the cellular level, the earliest stages of metastasis are difficult ...
Medical Xpress / Triple-dose regimen may permanently clear HIV in infected newborns
Every year, more than 120,000 newborns worldwide contract HIV, creating a global health burden that requires lifelong treatment for millions of people—assuming they have access and can afford it. New research led by Oregon ...
Phys.org / Pulsed radiofrequency magnetic fields may disorient migratory birds, experiments suggest
Every year, millions of migratory birds travel between different geographical regions on Earth to find food, escape cold weather or reach safe environments to raise chicks. To determine which direction to fly, these birds ...
Medical Xpress / Stem cells create humanlike heart valve tissue to model disease and test treatments
Melbourne researchers have created human heart valve tissues from stem cells, providing a powerful new platform to advance treatments for childhood heart diseases.
Phys.org / Illegal fishing captures up to 15% of global marine wild catch, analysis finds
Industrial-scale illegal fishing continues to undermine ocean sustainability, coastal livelihoods and global seafood markets—despite decades of regulation and recent advances in surveillance technology, according to new University ...
Phys.org / MRI study shows dogs can distinguish between human fear and sadness
Scientists—and dog lovers—have long known that dogs are remarkably good at interpreting our laughs, frowns and tears. But the biology behind this ability has remained largely unexplored until now. In a study published in ...
Tech Xplore / AI framework rooted in cognitive science could complete tasks more efficiently
In recent years, computer scientists have developed a wide range of artificial intelligence (AI) models that can rapidly recognize patterns in data, generate content and solve other computational problems. Many of these AI ...
Medical Xpress / Thyroid's two hormone-producing cell types develop separately before merging, study finds
The thyroid gland consists of two types of hormone-producing cells that regulate the body's metabolism and calcium balance. In mammals, these cell types merge into a single organ, whereas in other vertebrates, they develop ...
Phys.org / 'Lying mirror' uses structured surfaces to conceal optical information
Mirrors normally reveal what is placed in front of them, even when their curvature distorts a reflection. Researchers at the University of California, Los Angeles (UCLA) have introduced a different optical concept: a "lying ...
Tech Xplore / New engineering studies aim to slow battery aging while idle
Most batteries spend more than 70% of their lifetime at rest. Yet few studies have examined calendar aging, which is how a battery degrades when it is neither charging nor being used.
Phys.org / Climate debate remains dominated by established voices despite social media, research finds
When social media arrived on the scene, there were high hopes that they would improve—or even "democratize"—communication about climate change by, for instance, lowering access barriers, creating a more direct channel between ...
