Using light to precisely control cold receptors

LMU researchers have developed a molecule that allows an important ion channel to be regulated.

In the cell membrane, TRPM8 acts as a receptor for cold, enabling humans to sense cold. Researchers at Ludwig-Maximilians-Universitat have developed a photoswitchable TRPM8 channel activator based on the natural cooling agent menthol. This molecule called azo-menthol precisely controls TRPM8 channels using light. Azo-menthol can be switched ON and OFF with the precision of light.

Loneliness after losing a spouse, study

Persistent Loneliness After Spousal Loss, Despite Social Support

Researchers at Monash University found that losing a spouse causes one to feel more lonely and isolated despite support. Based on data taken from nearly 750 people who had lost their spouses, they found that loneliness and grief affected both genders similarly, with no significant differences based on wealth or health status.

A long-standing Jupiter’s cloud mystery solved

A misunderstanding about the composition of Jupiter’s clouds resolved.

A collaboration between amateur and professional astronomers has led to a major discovery about Jupiter's clouds, challenging a long-standing belief. Thanks to amateur astronomer Dr. Steven Hill, it’s now found that the clouds are not made of ammonia ice, but rather a mix of ammonium hydrosulphide and smog.

New tool to analyze embodied carbon in more than 1 million...

First ever visual analysis tool

However, due to a lack of data, the impact of embodied carbon in the built environment has been challenging to assess. To address that knowledge gap, Notre Dame researchers have created the first-ever visual analysis tool to evaluate embodied carbon in more than 1 million buildings in Chicago. Their research identifies 157 different architectural housing types in the city. It provides the first-ever visual analysis tool to evaluate embodied carbon at a granular level and to help inform policymakers seeking to strategically plan for urban carbon mitigation.

Early universe had more supermassive black holes than previously thought

Most distant and therefore oldest blazar ever seen.

The blazar, named J0410–0139, is located about 12.9 billion light-years away at the center of a galaxy. This makes it the most distant and oldest blazar ever observed. Scientists used multiple facilities, including the Very Large Array, Very Long Baseline Array, Chandra X-ray Observatory, and ALMA, to identify it.
