Climate extremes explain 18%-43% of global crop yield variations

Researchers from Australia, Germany and the US have quantified the effect of climate extremes, such as droughts or heatwaves, on the yield variability of staple crops around the world.

Monitoring the lifecycle of tiny catalyst nanoparticles

Nanoparticles can be used in many ways as catalysts. To be able to tailor them in such a way that they can catalyse certain reactions selectively and efficiently, researchers need to determine the properties of single particles …

Study shows drug reduces risk of relapse with neuromyelitis optica

The drug eculizumab, a synthetic antibody that inhibits the inflammatory response, significantly reduced the risk of relapse with neuromyelitis optica spectrum disorder (NMOSD). This rare but severe autoimmune inflammatory …

Study busts myths about gossip

A new UC Riverside study asserts that women don’t engage in “tear-down” gossip any more than men, and lower income people don’t gossip more than their more well-to-do counterparts. It also holds younger people are more likely …

Needleless vaccine will protect children from dangerous viruses

Orally administered vaccine can protect millions from hepatitis B. Oral vaccines are both safer and less expensive than injections. Therefore, researchers are continuously pursuing ways to produce an oral vaccine that is …

A new synthetic nanofactory inspired by nature

Bacteria across our planet contain nanometer-sized factories that do many different things. Some make nutrients, others isolate toxic materials that could harm the bacteria. We have barely scratched the surface of their functional …

Developing cells do synchronized swimming inside the embryo

The very beginnings of life inside a tiny developing embryo are mesmerizing to watch. Each movement and biochemical reaction is executed with well-ordered precision about 95 percent of the time, leading to the development …

A quantum leap in particle simulation

A group of scientists at the Department of Energy’s Fermilab has figured out how to use quantum computing to simulate the fundamental interactions that hold together our universe.

The mechanism behind the pluripotency-differentiation transition

Induced pluripotent stem cells can turn into any type of cell in the body or remain in their original form. In the current edition of Molecular Cell, scientists from the Helmholtz Zentrum München describe how cells decide …

Single molecule puts sperm on track

Sperm start their sprint to the ovum when they detect changes in the environment through a series of calcium channels arranged like racing stripes on their tails. A team of Yale researchers has identified a key molecule that …

Researchers find new brain mechanisms regulating body weight

Researchers at the University of Gothenburg, Sweden, have clarified the link between the molecule interleukin-6 (IL-6) in the brain and obesity. In experiments on rats and mice, they show that the molecule does affect the …

Laser-driven spin dynamics in ferrimagnets: How does the angular momentum flow?

When exposed to intense laser pulses, the magnetization of a material can be manipulated very fast. Fundamentally, magnetization is connected to the angular momentum of the electrons in the material. A team of researchers …
