How male sex steroids play a key role in understanding behavioral development — ScienceDaily

Researchers at the University of Maryland School of Medicine have discovered a mechanism for how androgens — male sex steroids — sculpt brain development. The research, conducted by Margaret M. McCarthy, Ph.D., who Chairs the Department of Pharmacology, could ultimately help researchers understand behavioral development differences between males and females. The research, published in Neuron,…

What causes that peak? Answering a long-standing question for covalent liquids — ScienceDaily

Materials that have a disordered structure with no regular repeating pattern are described as amorphous. Such materials can be found in nature and also have a variety of applications in technology. However, the disordered nature of these materials makes them more challenging to characterize than crystalline structures. Now, researchers at The University of Tokyo Institute…

Unusual property of the ultrastrong material could be harnessed for twisting or pulling motions — ScienceDaily

Spider silk, already known as one of the strongest materials for its weight, turns out to have another unusual property that might lead to new kinds of artificial muscles or robotic actuators, researchers have found. The resilient fibers, the team discovered, respond very strongly to changes in humidity. Above a certain level of relative humidity…

Indiana University researchers have invented technology to watch bacteria build cell walls in real time — ScienceDaily

Indiana University researchers are advancing knowledge about how bacteria build their cell walls that could contribute to the search for new antibacterial drugs. They have created a new tool to observe living cells in real time under a microscope. “If you look at the history, no one’s really discovered a fundamentally new class of antibiotic…
