Revenge of the seabed burrowers

The ancient burrowers of the seafloor have been getting a bum rap for years.These prehistoric dirt churners -- a wide assortment of worms, trilobites, and other animals that lived in Earth's oceans hundreds of millions of years ago -- are thought to have played a key role in creating the conditions needed for marine life to flourish. Their activities altered the chemical makeup of the sea itself...

Same difference: Two halves of the hippocampus have different gene activity

A study of gene activity in the brain's hippocampus, led by UT Southwestern researchers, has identified marked differences between the region's anterior and posterior portions. The findings, published today in Neuron, could shed light on a variety of brain disorders that involve the hippocampus and may eventually help lead to new, targeted treatments.

Scientists develop transparent electrode that boosts solar cell efficiency

Developing new ultrathin metal electrodes has allowed researchers to create semitransparent perovskite solar cells that are highly efficient and can be coupled with traditional silicon cells to greatly boost the performance of both devices, said an international team of scientists. The research represents a step toward developing completely transparent solar cells.

Solving a double murder arouses international interest

The technology using DNA-based genealogy that solved a double murder in Linköping opens completely new possibilities in investigating serious crime. LiU researchers are now involved in spreading new knowledge about the technology, which brings hope to police forces and has aroused major international interest.

Stem cell drugs surprise researchers: Could lead to better drugs in the future

Chemotherapy destroys stem cells, which then cannot develop into immune cells and become part of the body's defences. There are drugs that can remedy this, but previously we did not know exactly how these drugs worked. Now, a study conducted in mice by researchers at the University of Copenhagen details their function providing new knowledge that may improve stem cell transplantation and lead to...

UM research suggests social factors important for human-wildlife coexistence

University of Montana researchers recently published a new study in the Journal of Wildlife Management analyzing why landowners do or don't secure attractants in bear country. The results suggest that collective or socially motivated factors may be a missing and important piece of the puzzle for encouraging voluntary steps to secure attractants and improve wildlife-human coexistence. The...

Watch me move it, move it: Gliding structure in Mycoplasma mobile revealed

In collaboration with Kanazawa University, researchers from Osaka City University used high-speed atomic force microscopy (HS-AFM) to visualize at the nanometer level the movement of individual particles within the parasitic bacterium Mycoplasma mobile. After confirming the outline on the surface of the cell structure in an immobilized state with previous data gathered from electron microscopy,...
