Study identifies Key Neurons that Maintain Body Temperature at 37°C in Mammals

A research group at Nagoya University in Japan has reported that a group of neurons, called EP3 neurons, in the preoptic area of the brain play a key role in regulating body temperature in mammals. The finding could pave the way for the development of a technology that artificially adjusts body temperature to help treat heatstroke, hypothermia, and even obesity. The new study was published in the journal Science Advances.

Body temperature in humans and many other mammals is regulated at around 37°C (98.6°F), which optimizes all regulatory functions. When their body temperature noticeably deviates from the normal range, the functions are impaired, which could lead to heat stroke, hypothermia, and, in the worst case, death...

Lucky find! How Science behind Epidemics helped Physicists to develop State-of-the-Art Conductive Paint

Schematic of the structure of the film with graphene oxide trapped between polymer latex sphere

In new research published in Nature Communications, University of Sussex scientists demonstrate how a highly conductive paint coating that they have developed mimics the network spread of a virus through a process called ‘explosive percolation’ – a mathematical process which can also be applied to population growth, financial systems and computer networks, but which has not been seen before in materials systems. The finding was a serendipitous development as well as a scientific first for the researchers.

The process of percolation – the statistical connectivity in a system, such as when water flows through soil or through coffee grounds – is an important component in the development of l...

NASA Explores a Winter Wonderland on Mars

The HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter captured these images of sand dunes covered by frost just after winter solstice. The frost here is a mixture of carbon dioxide (dry) ice and water ice and will disappear in a few months when spring arrives. Credit: NASA/JPL-Caltech/University of Arizona

Cube-shaped snow, icy landscapes, and frost are all part of the Red Planet’s coldest season.
When winter comes to Mars, the surface is transformed into a truly otherworldly holiday scene. Snow, ice, and frost accompany the season’s sub-zero temperatures. Some of the coldest of these occur at the planet’s poles, where it gets as low as minus 190 degrees Fahrenheit (minus 123 degrees Celsius).

Cold as it is, don’t expect snow drifts worthy of the Rocky Mountains...

Treating Gut Pain via a Nobel Prize-Winning Receptor

Targeting a receptor responsible for our sense of touch and temperature, which researchers have now found to be present in our colon, could provide a new avenue for treating chronic pain associated with gastrointestinal disorders such as irritable bowel syndrome.

A team examining the colon, led by Professor Hongzhen Hu at Washington University and Professor Nick Spencer at Flinders University, identified the presence of Piezo2, the subject of the 2021 Nobel Prize in Physiology or Medicine, now known to be responsible for sensing light touch on our skin.

“In discovering that this receptor is also in our gut, there’s the potential that selectively targeting these channels could be used for long-term silencing of pain sensations from internal organs, without the need for frequent c...
