Medical Xpress / Common blood storage bags may leach microplastics into stored blood
In the 1970s, PVC bags revolutionized the storage of blood and blood products for transfusion. Disposable plastic (PVC) bags replaced reusable glass bottles, making the process more convenient and safer from contamination. ...
Phys.org / Astronomers catch 'Hatchling' quasar breaking out of its dusty cocoon
Using observations from multiple powerful telescopes, a team of astronomers studied a red quasar nicknamed "the Hatchling" at redshift 3.7. They may have identified one of the clearest examples yet of a quasar caught in transition ...
Phys.org / Nocturnal 'coffee frog' discovered in Costa Rica
A tiny greenish, nocturnal frog that thrives in coffee plantations has been discovered in Costa Rica's central Pacific region, where it also faces risks from agrochemicals used in farming.
Science X / HIV's hidden history: New study reveals much deeper roots stretching back millions of years
Researchers used to think that HIV and its relatives were pretty recent things, maybe only a few hundred years old. But a growing body of evidence now suggests their history is far more ancient, with viruses closely related ...
Phys.org / Gut cells may measure hunger by how watery their insides become
Researchers led by Sa Kan Yoo at the RIKEN Center for Biosystems Dynamics Research (BDR) in Japan have discovered that the natural turnover of gut cells in fruit flies depends on how much food the flies get, rather than on ...
Medical Xpress / Household hums below hearing range damage mouse kidneys in five-day experiment
Previous studies have hinted that people surrounded by more environmental noise—low, deep rumblings from air-conditioning units, elevator motors, distant traffic and ventilation ducts—tend to have worse kidney function. But ...
Phys.org / Phages unlock essential vitamin B12 by bursting open gut bacteria
All living organisms need vitamin B12 to form red blood cells and DNA, as well as to build and support brain and nerve cells. But it's hard to come by: Humans don't make it. Animals don't make it. Plants don't make it. In ...
Medical Xpress / Radiopharmaceutical may benefit patients with metastatic prostate cancer sooner
Earlier use of a targeted radionuclide therapy delays metastatic prostate cancer progression when administered as part of a trio of drugs, according to a Phase III clinical trial led by Weill Cornell Medicine, NewYork-Presbyterian, ...
Medical Xpress / Parkinson's-linked α-synuclein blocks protein transport in neurons, disrupting cells' waste recycling
Parkinson's disease affects more than 10 million people worldwide. The disease is characterized by the buildup of abnormal clumps of the protein alpha-synuclein inside brain cells, but scientists have long struggled to understand ...
Tech Xplore / Human-aware robots adapt to partners, reducing back strain during team lifting
When people work in pairs or teams, they can often solve a wider range of problems, completing some tasks faster and more efficiently than they would alone. To assist users similarly to how other humans would, robots should ...
Phys.org / Silver nanocatalysts switch reaction sites between power generation and hydrogen production
For the first time, researchers have discovered that the same silver (Ag) nanocatalyst operates at different reaction sites depending on whether a solid oxide cell is generating electricity or producing hydrogen. This finding ...
Phys.org / One million years without sex fails to erase stick insects' unused biological system
Scientists have made a surprising finding about how an asexually reproducing stick insect has evolved. Research led by Dr. Darren Parker, lecturer in evolutionary biology at Bangor University, studied the genes of several ...
