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 ...

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 ...

Phys.org / How egg cells control the timing of cell division
A protein known as MPS1 helps to ensure that a key process during cell division of oocytes—unfertilized egg cells—occurs in a timely manner, RIKEN biologists have discovered. This finding in mice may have implications ...

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 / 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 / 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 / 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 ...

Phys.org / NASA's GUARDIAN tsunami detection tech catches a wave in real time
A massive earthquake and subsequent tsunami off Russia in late July tested an experimental detection system that had deployed a critical component just the day before.

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 ...

Tech Xplore / Software tool turns everyday objects into animated, eye-catching displays—without electronics
Whether you're an artist, advertising specialist, or just looking to spruce up your home, turning everyday objects into dynamic displays is a great way to make them more visually engaging. For example, you could turn a kids' ...

Phys.org / Benchmark study tracks trends in dog behavior
A new Virginia Tech study published in PLOS One establishes a crucial baseline for understanding dog behavior on a large scale.

Phys.org / RNA technology 'hacks' into phage replication, offering new insights into molecular interactions
Bacteriophages, or phages for short, are viruses that infect bacteria. Using phages therapeutically could be very useful in fighting antibiotic-resistant pathogens, but the molecular interactions between phages and host bacteria ...
