Phys.org / Newly discovered cell machinery breaks down protein aggregates into smaller pieces before 'taking it to the trash'
A new study from Aarhus University shows that our cells' ability to clean out old protein clumps, known as aggregates, also includes a—up till now unknown—partnership with an engine that breaks down bigger pieces into ...
Phys.org / Animal bones found in Late Bronze Age rubbish heaps show the distances people traveled to feast
Middens, massive prehistoric rubbish heaps which became part of the British landscape, are revealing the distances people traveled to feast together at the end of the Bronze Age.
Medical Xpress / Breaking the code of sperm motion: Two proteins found vital for male fertility
There are many potential causes of infertility, and it can be challenging to pin down just what the problem is when a couple is having trouble getting pregnant. Now, researchers show that a few key proteins have a major effect ...
Phys.org / Warming rivers in Alaska threaten Chinook salmon populations and Indigenous food security
For millennia, Indigenous people living in Alaska and Canada's Yukon territory have relied on Chinook salmon. The large, fatty fish provide essential nutrients for Arctic living and have influenced traditions and languages ...
Medical Xpress / A 'universal' therapy against the seasonal flu? Antibody cocktail targets virus weak spot
An unusual therapy developed at The Jackson Laboratory (JAX) could change the way the world fights influenza, one of the deadliest infectious diseases. In a new study in Science Advances, researchers report that a cocktail ...
Medical Xpress / Surprising new roles discovered for known blood cancer gene DNMT3A
A gene called DNMT3A is important for guiding blood stem cells into forming all the cell types present in blood, including red blood cells, white blood cells and platelets. When this gene accumulates mutations—which might ...
Phys.org / Invasive flathead catfish now top predators in Susquehanna River in Pennsylvania
Flathead catfish, opportunistic predators native to the Mississippi River basin, have the potential to decimate native and recreational fisheries, disrupting ecosystems in rivers where they become established after their ...
Phys.org / Scientists develop faster technique to uncover hidden gene switches
Researchers at the Max Delbrück Center have developed a new method to discover how DNA controls genes. Their technique, published in Cell Genomics, can reveal the genetic "switches" that regulate important genes more quickly ...
Phys.org / Octopuses put their best arm forward for every task
Octopuses can use any of their arms to perform tasks, but tend to use a particular arm, or arms, for specific tasks. This finding, presented in a paper in Scientific Reports, reveals more about the complex behavior these ...
Phys.org / Fat molecules and water interact in surprising ways within collagen fibrils
Researchers from the Faculty of Natural Sciences at Chemnitz University of Technology have discovered fat molecules in natural collagen fibrils, the main component of connective tissue. Their research, published in Soft Matter, ...
Phys.org / Cell memory can act more like a dimmer dial than an on/off switch
When cells are healthy, we don't expect them to suddenly change cell types. A skin cell on your hand won't naturally morph into a brain cell, and vice versa. That's thanks to epigenetic memory, which enables the expression ...
Phys.org / Mysterious flag-waving behavior in a tropical bug is an anti-predator strategy
If you happen to be walking in the forests of Panama, you might just come across a bug that will wave at you, which scientists at the Smithsonian Tropical Research Institute (STRI) have been studying for a while. The matador ...
