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 machinery to fight disease.

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 rock layers beneath the Jezero crater. The variations could indicate past lava flows or possibly a river delta even older than the one currently being...

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 on their front paws.

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 that it could successfully be used for both daytime and nighttime cloaking.

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 -- exactly in such a way that the beam of light blocks itself and can no longer leave the system. Thus, the light has no choice but to be absorbed by the...

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 Perseverance rover collected samples from sites on the crater floor and identified igneous rocks that, once dated on Earth, will provide a timeline for...

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 human-specific -- features, they report.

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.

Scientists made a surprising discovery about the composition of rock in Jezero Crater, one that will help them get a better idea of when water existed on Mars, and ultimately, help them understand if the red planet was ever habitable to microbial life.

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 obesity drugs.

New research offers insights into a line of CRISPR systems, which could lead to promising antiviral and tissue engineering tools in animal and plants.

What makes people share posts on social media? A new study reveals that we share the social media posts we think are most relevant to ourselves or to our friends and family.

In Alzheimer's Disease and other neurodegenerative dementias, proteins that normally play a role in healthy brain tissue turn bad, clumping together to form insoluble plaques and tangles as neurons wither and die. New research from reveals a novel role for how one of these proteins, tau, functions in healthy nerve cells, bringing us closer to understanding how it could be involved in pathology.

Using new scientific tools, archaeologists discovered that an ancient Greek leader known today as the Griffin Warrior likely grew up around the seaside city he would one day rule. The findings are part of three new studies that examined the ancient DNA of the Griffin Warrior and 726 other people who lived before and during the Bronze Age to learn more about their origins and movements across three...

The pilot study is one of the first to indicate that neurofeedback could help address cognitive deficits of cancer patients experiencing 'chemo brain.'

People who were more distressed -- showing signs of anxiety or depression -- during the COVID-19 pandemic were less likely to follow some best practice recommendations from the Centers for Disease Control and Prevention, according to a new study. However, those same people were more likely than their non-distressed peers to get vaccinated. The authors refer to this as differential distress: when...

Adding to a growing body of research on mental health and the human microbiome, a new study compared the bacteria in the saliva of students with and without recent thoughts of suicide, called suicidal ideation.
