Bonn University.
These specialized cells, once thought to merely insulate nerve fibers or maintain proper operating conditions for neurons, are now believed to play a significant role when it comes to understanding our surroundings. This breakthrough discovery was reported in the journal Nature Communications.

Military probing whether cancers linked to nuclear silo work
Posted by Genevieve Klien in categories: biotech/medical, military, nuclear weapons
Nine military officers who had worked decades ago at a nuclear missile base in Montana have been diagnosed with blood cancer and there are “indications” the disease may be linked to their service, according to military briefing slides obtained by The Associated Press. One of the officers has died.
All of the officers, known as missileers, were assigned as many as 25 years ago to Malmstrom Air Force Base, home to a vast field of 150 Minuteman III intercontinental ballistic missile silos. The nine officers were diagnosed with non-Hodgkin lymphoma, according to a January briefing by U.S. Space Force Lt. Col. Daniel Sebeck.
Missileers ride caged elevators deep underground into a small operations bunker encased in a thick wall of concrete and steel. They remain there sometimes for days, ready to turn the launch keys if ordered to by the president.

Anti-aging gene shown to rewind heart age
Posted by Josh Seeherman in categories: biotech/medical, life extension
By ten years.
An anti-aging gene discovered in a population of centenarians has been shown to rewind the heart’s biological age by 10 years. The breakthrough, published in Cardiovascular Research and led by scientists at the University of Bristol and the MultiMedica Group in Italy, offers a potential target for patients with heart failure.
Associated with exceptional longevity, carriers of healthy mutant genes, like those living in blue zones of the planet, often live to 100 years or more and remain in good health. These individuals are also less prone to cardiovascular complications. Scientists believe the gene helps to keep their hearts young by protecting them against diseases linked to aging, such as heart failure.

Alleviating Symptoms: Brain Stimulation Could Help Treat Alzheimer’s Disease
Posted by Jose Ruben Rodriguez Fuentes in categories: biotech/medical, chemistry, neuroscience
Alzheimer’s disease, which is the most common form of dementia, is challenging to treat. A possible therapy is deep brain stimulation delivered by a pacemaker-like device. A team of researchers from Charité – Universitätsmedizin Berlin discovered that stimulating a specific network in the brains of Alzheimer’s patients can decrease their symptoms. The study, published in the journal Nature Communications.
<em>Nature Communications</em> is a peer-reviewed, open-access, multidisciplinary, scientific journal published by Nature Portfolio.

Sound of the Hunga Tonga Volcanic Eruption

Escucha Sound of the Hunga Tonga Volcanic Eruption de European Space Agency en #SoundCloud
One year ago, the Hunga Tonga-Hunga Ha’apai volcano erupted, causing widespread destruction to the Pacific Island Nation of Tonga. It spewed volcanic material up to 58 km into the atmosphere, brought a nearly 15 m tsunami that crashed ashore, destroying villages, and created a sonic boom that rippled around the world – twice. Even one year on, interest in the extraordinary explosive eruption remains. A sound artist has recently recreated the sonification of the underwater volcanic eruption using rayleigh signal intensity data provided by the Aeolus Virtual Research Environment platform. Using wind data obtained on one of its overpasses over the ash cloud of the Hunga Tonga explosion, Jamie Perera used an audio sample of one of the shock waves, time-stretched it into a ghostly tone, and assigned it to harmonic values transcribed from 90 Aeolus readings taken over a duration of approximately 15 minutes. The listener hears one reading every two seconds, in a harmonic range that spans six piano octaves, the highest of which can be heard at around 01:18 minutes when the readings show the eruption’s dust plume at its highest peak (over 20.5 km). The artistic intention behind the sonification was to evoke the otherworldly landscape of Hunga Tonga and other volcanoes. Sonification credit/copyright: @jamieperera (2023). Used by permission.

Taste Cells’ Role in Immune Response May Lead to Treatment of Taste Loss
Posted by Jose Ruben Rodriguez Fuentes in categories: biotech/medical, life extension
Summary: A subset of taste cells may play a key role in the body’s immune response to harmful oral microbes. The findings could help taste loss associated with infections, aging, and dysregulation of the oral microbiome caused by chemotherapy.

Taste cells are heavily exposed to the microbes in the mouth, but their role in helping the body respond to those microbes has not yet been studied in detail.
