Researchers discover the conditions inside tiny pores can have big consequences for chemistry.

When a plant senses a microbial invasion, it makes radical changes in the chemical soup of proteins — the workhorse molecules of life — inside its cells. A new study reveals the key components in plant cells that reprogram their protein-making machin…

NASA’s Perseverance landed on Mars in February 2021 and has been gathering data on the planet’s geology and climate and searching for signs of ancient life. The rover’s subsurface radar experiment has returned images showing unexpected variations in ro…

A researcher is suggesting changes to fur trapping practices to help prevent the accidental amputation of grizzly bear toes. The research is calling attention to a small number of grizzly bears in the southeast corner of British Columbia missing toes o…

For the purpose of personalised therapies, a research group has used 3D printing to develop tablets based on different types of starch, and has confirmed that drug release could be tailored by optimizing the right starch type and tablet shape.

A research team has developed a new reflective coating that can be used in counter-surveillance military applications to provide camouflage under the scrutiny of thermal imaging cameras. Their tests of the thermal camouflage effect were so promising th…

A new paper shows how people’s everyday lives can have significant global consequences when establishing policies to achieve sustainability.

Mechanical engineers develop a textile-based energy harvesting shoe able to power assistive devices for people with disabilities.

A new class of molecular motors triggered by visible light kills harmful bacteria by generating reactive oxygen species. The new strategy could be a weapon against antibiotic-resistant bacteria.

A new modeling tool helps prioritize novel and known viruses for zoonotic risk. It shows coronaviruses are riskiest for spillover to humans.

A surprising trick that allows a beam of light to be completely absorbed even in the thinnest of layers: Using mirrors and lenses, a ‘light trap’ can be constructed, in which the light beam is steered in a circle and then superimposed on itself — exac…

One main goal of NASA’s Mars 2020 mission is to determine when conditions on the planet were conducive to the formation of liquid water. Hence the target Jezero crater, seemingly a lakebed with a delta potentially formed by an inflowing river. The Pers…

What makes the human brain distinct from that of all other animals — including even our closest primate relatives? In an analysis of cell types in the prefrontal cortex of four primate species, researchers identified species-specific — particularly h…

A vast paleogenetic study reveals insights on migration patterns, the expansion of farming and language development from the Caucasus over western Asia and Southern Europe from the early Copper Age until the late middle ages.

When our eyes move during REM sleep, we’re gazing at things in the dream world our brains have created, according to a new study. The findings shed light not only into how we dream, but also into how our imaginations work.

A new universal flu vaccine protects against diverse variants of both influenza A and B viruses in mice, according to a new study.

A new paper looks outside this brain region and reviews the various brain pathways that meet in the brain stem to control feeding behavior, using a technique that offers an unbiased look at the neurons involved, which could offer targets for better obe…
