Switching tracks: Reversing electrons’ course through nature’s solar cells

Think of a train coming down the tracks to a switch point where it could go either to the right or the left — and it always goes to the right. Photosynthetic organisms have a similar switch point. New research from Washington University in St. Loui...

Lasers Learn to Accurately Spot Space Junk

Scientists have developed space junk identification systems, but it has proven tricky to pinpoint the swift, small specks of space litter. A unique set of algorithms for laser ranging telescopes, described in the Journal of Laser Applications, by AIP...

Why It Matters: Prescription for Disaster

Bacteria are becoming increasingly resistant to antibiotics. A major cause is their overuse in both humans and animals. At the same time, a lack of financial incentives is setting back efforts to discover new classes of antibiotics. The problem is bo...

Life could have emerged from lakes with high phosphorus

Life as we know it requires phosphorus, which is scarce. How did the early Earth supply this key ingredient? A University of Washington study, published Dec. 30 in the Proceedings of the National Academy of Sciences, finds answers in certain types of...

How Cells Learn to “Count”

One of the wonders of cell biology is its symmetry. Mammalian cells have one nucleus and one cell membrane, and most humans have 23 pairs of chromosomes. Trillions of mammalian cells achieve this uniformity — but some consistently break this mold t...

Gut Bacteria Found to Have a Shocking Secret

Scientists studied how the bacteria transport electrons across their cell wall. The bacteria use a method that’s different from other, known electricity-producing bacteria. They also found that hundreds of other bacterial species use this same proc...

Chimpanzees More Likely to Share Tools, Teach Skills When Task Is Complex

Teach a chimpanzee to fish for insects to eat, and you feed her for a lifetime. Teach her a better way to use tools in gathering prey, and you may change the course of evolution.For most wild chimpanzees, tool use is an important part of life — but...

Paving the way for spintronic RAMs: A deeper look into a powerful spin phenomenon

Scientists at Tokyo Institute of Technology(Tokyo Tech) explore a new material combination that sets the stage for magnetic random access memories, which rely on spin--an intrinsic property of electrons-- and could outperform current storage devices....

Snowmageddon warnings in North America come from tropics more than Arctic stratosphere

Winter weather patterns in North America are dictated by changes to the polar vortex winds high in the atmosphere, but the most significant cold snaps are more likely influenced by the tropics, scientists have found.

Droughts Spell Changes for Soil Microbes

Scientists predict a warming Earth will cause more droughts that are more severe in the grasslands of the central United States. This research found that soil drying affects the microbial community in several ways.

Predicting How Microbial Neighbors Influence Each Other

Researchers developed a new theoretical framework called minimal interspecies interaction adjustment (MIIA). It predicts how surrounding organisms and other factors drive changes in interactions in microbial communities.

Simplifying Microbial Consortia Opens a Path to Understanding Soil Community Ecology

New research demonstrates that microbial communities that are simplified but still representative may offer a way to explore more complex ones. In particular, they can help scientists uncover the mechanisms that drive the ecology of groups of soil mi...
