‘Teenage Galaxies’ are Unusually Hot, Glowing with Unexpected Elements

Posted by in categories: chemistry, cosmology, evolution, physics

Similar to human teenagers, teenage galaxies are awkward, experience growth spurts and enjoy heavy metal — nickel, that is.

A Northwestern University-led team of astrophysicists has just analyzed the first results from the CECILIA (Chemical Evolution Constrained using Ionized Lines in Interstellar Aurorae) Survey, a program that uses NASA’s James Webb Space Telescope (JWST) to study the chemistry of distant galaxies.

According to the early results, so-called “teenage galaxies” — which formed two-to-three billion years after the Big Bang — are unusually hot and contain unexpected elements, like nickel, which are notoriously difficult to observe.

Research suggests that dinosaurs may have influenced how human beings age

Posted by in categories: biotech/medical, life extension

Science: Research suggest that dinosaurs 🦕 🦖 may have influenced how humans age today.

Human aging may have been influenced by millions of years of dinosaur domination according to a new theory from a leading aging expert. The ‘longevity bottleneck’ hypothesis has been proposed by Professor Joao Pedro de Magalhaes from the University of Birmingham in a new study published in BioEssays. The hypothesis connects the role that dinosaurs played over 100 million years with the aging process in mammals.

While some reptiles and amphibians show no significant signs of aging, all mammals—including humans—show a marked .

Brain Scans From Former NFL Players Identify Repair Protein in the Brain

Posted by in categories: biotech/medical, neuroscience

In a new study using brain scans of former NFL athletes, Johns Hopkins Medicine researchers say they found high levels of a repair protein present long after a traumatic brain injury such as a concussion takes place. The repair protein, known as 18 kDa translocator protein (TSPO), is known to be present in the brain at high levels in the immediate aftermath of brain injury as part of the inflammatory response and to facilitate repair. The new findings, published Oct. 30 in JAMA Network Open, suggest that brain injury and repair processes persist for years after players end collision sports careers, and lead to long-term cognitive problems such as memory loss.

“The findings show that participating in repeated collision sports like football may have a direct link to long-term inflammation in the brain,” says Jennifer Coughlin, M.D., associate professor of psychiatry and behavioral sciences at the Johns Hopkins University School of Medicine. Ongoing studies like the current one, she says, add details about how the brain heals — or doesn’t — and how repeated brain injuries, even mild ones that players routinely shake off, may over time affect cognitive abilities.

Firefly Aerospace’s new rocket engine spouts green flames in 1st ‘hot fire’ test (photo)

Posted by in category: space travel

Firefly Aerospace conducted the first hot fire test of its new Miranda rocket engine, producing a massive plume of green flames.

Firefly’s Miranda engine is slated to be used on the first stage of Northrop Grumman’s Antares 330 rocket as well as the Medium Launch Vehicle (MLV) the two companies are developing together. The Antares 330 rocket is designed to carry more than 22,000 lbs of cargo to the International Space Station (10,000 kg), while the MLV will be able to loft 35,000 lbs (16,000 kg) of payload to low Earth orbit.
