Hints of an atmosphere on TRAPPIST-1e raise hopes it could be a watery, potentially habitable world. Astronomers using the James Webb Space Telescope are unraveling the mysteries of TRAPPIST-1e, an Earth-sized exoplanet 40 light years away that could harbor liquid water. Early data suggests hints of an atmosphere, but much remains uncertain. Researchers have already ruled out a hydrogen-rich primordial atmosphere, pointing instead to the possibility of a secondary atmosphere that could sustain oceans or ice.

People who sleep poorly are more likely than others to have brains that appear older than they actually are. This is according to a comprehensive brain imaging study from Karolinska Institutet, published in the journal eBioMedicine. The paper is titled “Poor sleep health is associated with older brain age: the role of systemic inflammation.”

Increased inflammation in the body may partly explain the association.

Poor sleep has been linked to dementia, but it is unclear whether unhealthy sleep habits contribute to the development of dementia or whether they are rather early symptoms of the disease.

In a new study, researchers at Karolinska Institutet have investigated the link between sleep characteristics and how old the brain appears in relat...

New research led by the University of Cambridge, in collaboration with Hong Kong University of Science and Technology (GZ) and Queen Mary University of London, could redefine how we interact with everyday tools and devices—thanks to a novel method for printing ultra-thin conductive microfibers.

Imagine fibers thinner than a human hair (nano- to micro-scale in diameter) that can be tuned on-demand to add sensing, energy conversion and electronic connectivity capabilities to objects of different shapes and surface textures (such as glass, plastic and leather)...

Scientists digging through data collected by the Cassini spacecraft have found new complex organic molecules spewing from Saturn’s moon Enceladus. This is a clear sign that complex chemical reactions are taking place within its underground ocean. Some of these reactions could be part of chains that lead to even more complex, potentially biologically relevant molecules.

Published in Nature Astronomy, this discovery further strengthens the case for a dedicated European Space Agency (ESA) mission to orbit and land on Enceladus.

In 2005, Cassini found the first ...
