Medical Xpress / Scientists map brain's mysterious 'blue place' and discover longest neuron ever measured in a mouse

Deep in the brainstem sits a small but important cluster of neurons known as the locus coeruleus (LC), Latin for "blue place." It makes up a tiny fraction of the brain's cells but plays an important role by releasing the ...

Phys.org / Building big with DNA gets a software upgrade

Forty-four years ago, Nadrian Seeman published his groundbreaking ideas on using DNA as a structural material, expanding DNA's significance far beyond its role as a carrier of genetic information. Since then, the steadily ...

Phys.org / Two spike 'keys' work together to let SARS-CoV-2 enter cells, study reveals

To enter cells, the COVID-19 virus fuses its surrounding membrane with the membrane of the target cell. This is where the fusion peptides of the spike protein come into play. These regions function as molecular keys that ...

Phys.org / Threatened bumblebee populations in England and Wales face severe genetic declines

A new study reveals that an important pollinator is rapidly losing genetic diversity in Britain. Moss carder bumblebees were once widespread across the UK, living in flower-rich meadows, marshes and heathlands, where they ...

Phys.org / Greenhouse gas benefits of agricultural irrigation far outweigh emissions costs, study finds

Irrigating U.S. crops prevents higher greenhouse gas emissions by avoiding land conversion, new research by Colorado State University shows. Agricultural irrigation allows the United States to grow more food on less land. ...

Tech Xplore / Steelmaking waste could store solar energy, with electric arc furnace slag leading early tests

Storing energy as heat is a proven pathway to address the challenge solar power faces when it's dark or cloudy outside by enabling the capture, storage and on-demand release of thermal energy. The process, called high-temperature ...

Medical Xpress / Higher physical activity may prevent more type 2 diabetes cases among older adults

New research being presented at the Annual Meeting of the European Association for the Study of Diabetes (EASD) in Milan, Italy (Sept. 28–Oct. 2), suggests that higher levels of moderate-to-vigorous physical activity (MVPA) ...

Phys.org / Hot electrons reveal electronic collisions may raise resistance in twisted graphene

When a material heats up, its electrical resistance often rises. The harder question is what, exactly, is getting in the way. The electrons carrying the current may be scattered by vibrations of the material's atomic lattice, ...

Phys.org / Iron, sulfur and purple light unlock greener carbon-carbon bond formation

Much of organic chemistry, including the type used to create and alter medicinal drugs, relies on modifying carbon bonds. Rice University's Julian West has been developing a less expensive, faster and more environmentally ...

Phys.org / The Mediterranean is getting warmer and saltier at an ever-faster pace—even thousands of meters below the surface

Across its basins and thousands of meters down, the Mediterranean Sea is getting warmer and saltier. Now, a new study finds it is also doing so at an increasingly rapid pace. The speedup is largest in the central and eastern ...

Phys.org / Global database reveals hidden diversity and potential of deep-sea microbes

The ocean's aphotic zone—the dark, high-pressure region below the surface, where sunlight cannot reach—is home to a vast wealth of microbial life. Yet scientists know relatively little about the genetic makeup, growth and ...
