It could be used in anything from self-fitting bras to actuating textiles for medical therapeutics and could...
Some male butterflies seal their mate's genitalia with a waxy 'chastity belt' to prevent future liaisons. But female butterflies can fight back. Could this sexual one-upmanship ultimately result in new species?
Imagine a reusable face mask that protects wearers and those around them from SARS-CoV-2, is comfortable enough to wear all day, and stays in place without frequent adjustment. Based on decades of experience with filtration and textile materials, researchers have designed a new mask intended to do just that -- and are providing the plans so individuals and manufacturers can make it.
Adolescence is a difficult period of development, made more complex for those with Type 1 diabetes mellitus (T1DM). The challenges of managing multiple doses of daily insulin administration, blood glucose monitoring, dietary and exercise requirements, can make self-care difficult and complicate outcomes. Adolescents with T1DM often have poorer diabetes outcomes than others, indicating that glucose...
In our Solar System, the eight planets and many other minor objects orbit in a flat plane around the Sun; but in some distant systems, planets orbit on an incline -- sometimes a very steep one. New work could explain the architecture of multi-star systems in which planets are separated by wide gaps and do not orbit on the same plane as their host star's equatorial center.
Researchers have solved the the structure of the complex formed when mRNA is being scanned to find the starting point for translating RNA into a protein. The discovery provides a new understanding of this fundamental process.

Neuroscientists have found a way to estimate, with some degree of accuracy, a time frame for when Alzheimer's is most likely to strike in a person's lifetime, based on their baseline sleep patterns. Their findings suggest one defense against this virulent form of dementia -- for which no treatment currently exists -- is deep, restorative sleep, and plenty of it.
New research demonstrates that a candidate COVID-19 vaccine elicited robust immune response in Syrian golden hamsters and prevented severe clinical disease -- including weight loss, pneumonia and death.
As we get older, many of our body's processes start slowing down. For instance, a cut on the hand will take longer to heal after middle age than in youth. That said, it still heals.
Scientists have discovered how to capture 'live' images of immune cells inside the lungs. The group is the first in the world to find a way to record, in real time, how the immune system battles bacteria impacting the alveoli, or air sacs, in the lungs of mice. The discovery has already provided new insights about the immune systems' cleaners, called alveolar macrophages.
Two major theories have fueled a now 1,500 year-long debate started by Saint Augustine: Is consciousness continuous, where we are conscious at each single point in time, or is it discrete, where we are conscious only at certain moments of time? Psychophysicists answer this centuries-old question with a new model, one that combines both continuous moments and discrete points of time.
A new study published in Current Biology reveals that the ability for humans to digest milk (lactase persistence) spread through Central Europe quickly in evolutionary terms.
