Scientists have reversed some signs of aging in a study on mice

Posted by in categories: biotech/medical, genetics, life extension

Mice who ate a diet high in fat and cholesterol were more likely to see their hair turn from black to white and experience hair loss. The diet also appeared to cause inflammation of the skin.

In the first stage of the study, the researchers genetically modified mice to develop atherosclerosis, a condition in which fat deposits form in the arteries.

They then fed mice either a Western diet high in fat and cholesterol or untreated rat chow from the age of 12 to 20 weeks. As expected, the mice who consumed the Western diet saw their hair turn white and fall out, and develop skin lesions. And the longer the mice ate the diet, the worse their symptoms became. By week 36, three quarters of the animals had skin lesions.

Fresh Solution for Smelly Feet From Breakthrough Nano-Particle Technology

Posted by in categories: biotech/medical, government, military, nanotechnology

New research[1] presented at the 29th EADV Congress, EADV Virtual, shows that socks coated in zinc oxide nanoparticles (ZnO-NPs) can prevent bromodosis (foot odor) and pitted keratolysis (bacterial infection causing smelly feet), reducing the negative impact this embarrassing condition has on quality of life.[2]

Developed by the Royal Thai Airforce, the ZnO-NP-coated socks were trialed in a real-life setting by researchers at Siriraj Hospital, Mahidol University in Thailand. They found that the antibacterial efficacy of ZnO-NPs, along with its safety and compatibility with human skin, makes it the perfect compound to incorporate into textiles, including socks, to prevent unpleasant foot odor.

The double-blinded, randomized, controlled trial was conducted with 148 cadets at the Thai Naval Rating School. Bromodosis and pitted keratolysis are a common complaint in military personnel, with foot lesions, including pitted keratosis, occurring in over a third of naval cadets in Thailand (38.5%).[2]

Citizen astronomers reshape asteroids from their backyard

Posted by in category: alien life

There are nearly one million catalogued asteroids, but we don’t know much about many of them. Now Unistellar and its scientific partner, the SETI Institute, can count on a network of nearly 3,000 amateurs capable of observing thousands of asteroids and providing an estimate of their size and shape. With mobile stations located in Asia, North America and Europe, the Unistellar network, the largest network of citizen astronomers, participates in cutting-edge research and has delivered its first scientific results including the 3D shape model of an asteroid and the size of another one.

“The Unistellar eVscope is more than a telescope. It’s also a tool to access a network made of citizen astronomers throughout the world who can observe together and participate in scientific campaigns,” said Franck Marchis, senior planetary astronomer at the SETI Institute and Chief Scientific Officer at Unistellar. “Today more than 150 people have already contributed to our campaigns and collected valuable scientific data from their backyard.”

In addition to the SETI Institute, Marchis’ group collaborated with Josef Hanuš and Josef Ďurech of the Institute of Astronomy at Charles University to identify potential targets of interest in the asteroid population. “After having designed and validated our data analysis pipeline in 2020, we can now routinely propose campaigns to our citizen astronomers,” said Marchis.

Brainstem Neurons Control Both Behavior and Misbehavior

Posted by in category: neuroscience

Summary: Study reveals how gene control mechanisms determine the identity of neurons in the embryonic brainstem. A failure in differentiation in developing brainstem neurons can lead to behavioral abnormalities, including ADHD.

A recent study at the University of Helsinki reveals how gene control mechanisms define the identity of developing neurons in the brainstem. The researchers also showed that a failure in differentiation of the brainstem neurons leads to behavioural abnormalities, including hyperactivity and attention deficit.

Bengaluru Engineers Create World’s First Plastic As Strong As Steel, While Staying Lightweight

Posted by in categories: chemistry, transportation

If this thing becomes successful, I think it could enable plastics to replace steel in a lot of vehicles and machinery.

Engineers are always on the lookout for materials that can improve the performance of their existing products. Carmakers too are always on the lookout to make lighter yet stronger parts to help cars perform better. And, in most cases, these solutions come at a pretty hefty cost.

World’s record entanglement storage sets up a milestone for Quantum Internet Alliance

Posted by in categories: computing, internet, quantum physics

Researchers from Sorbonne University in Paris have achieved a highly efficient transfer of quantum entanglement into and out of two quantum memory devices. This achievement brings a key ingredient for the scalability of a future quantum internet.

A quantum internet that connects multiple locations is a key step in quantum technology roadmaps worldwide. In this context, the European Quantum Flagship Programme launched the Quantum Internet Alliance in 2018. This consortium coordinated by Stephanie Wehner (QuTech-Delft) consists of 12 leading research groups at universities from eight European countries, in close cooperation with over 20 companies and institutes. They combined their resources and areas of expertise to develop a blueprint for a future quantum internet and the required technologies.

A quantum internet uses an intriguing quantum phenomenon to connect different nodes in a network together. In a normal network connection, nodes exchange information by sending electrons or photons back and forth, making them vulnerable to eavesdropping. In a quantum network, the nodes are connected by , Einstein’s famous “spooky action at a distance.” These non-classical correlations at large distances would allow not only secure communications beyond direct transmission but also distributed quantum computing or enhanced sensing.
