Older mice that received a faecal microbiome transplant from younger animals went on to have improved brain plasticity, which suggests their brains could overcome a neurological condition that is typically successfully treated only in childhood
Fungi are key constituents of the soil microbial community, playing a major role in moving carbon and energy through the soil food web. A recent analysis carried out by Professor Matthias C. Rillig from Freie Universität Berlin highlights the importance of soil fungal
Superfluids are intriguing states of matter in which particles behave like a giant collective wave, allowing them to flow without any friction. When this fluid flows past a fixed obstacle at a velocity below a specific threshold, it moves around it without slowing down or
In biology, cytokinins were long considered regulators exclusive to the plant kingdom, where they control, among other things, growth and responses to stress. Until now, little research has been conducted into whether these substances might also play a significant role in the
Something is absorbing light on the surfaces of Pluto and Saturn’s moon Titan, and figuring out what it is could be crucial to understanding Titan’s complex chemistry
New research suggests the microbiome near the surface of a plant's roots, known as the rhizosphere microbiome, may play a role in helping crops respond to heat stress.
Instagram use could influence not only how we see our bodies, but also how our brain perceives the bodies we inhabit as "ours." In short, it could erode our sense of self to the point of no longer recognizing ourselves in our own bodies, or feeling "at home" within them.
Efficiency ratings on portable air conditioners don’t give consumers the full picture, and one type of aircon unit is so inefficient that it should be banned, says Michael Le Page
In the future, microorganisms could help return hard-to-recycle plastics to the recycling loop. Nick Wierckx, a molecular biologist at Jülich, explains the opportunities offered by biological recycling processes and the challenges of a truly circular economy.
Many young adults are familiar with common species such as dandelions or sparrows. In contrast, plants and birds typical of fields, meadows and other agricultural habitats are significantly less well known. This is shown by a new study from the Leibniz Centre for Agricultural
A biocontainment facility designed to protect Earth from potentially hazardous biotic contaminants from space should be part of a planned NASA base on the moon, a policy paper maintains.
Scientists have demonstrated a noninvasive technique that uses light to reveal the hidden contents of chicken eggs, potentially helping to curb the meat industry's practice of killing billions of male chicks at birth. The study, published in Newton, found that when light enters
