27 million ancestors — ScienceDaily
Researchers from the University of Oxford’s Big Data Institute have taken a major step towards mapping the entirety of genetic relationships among humans: a single genealogy that traces the ancestry…
Neuroscientists have identified a population of neurons in the human brain that respond to singing but not other types of music — ScienceDaily
For the first time, MIT neuroscientists have identified a population of neurons in the human brain that lights up when we hear singing, but not other types of music. These…
How some gut microbes awaken ‘zombie’ viruses in their neighbors — ScienceDaily
Some gut bacteria have a spooky superpower: they can reanimate dormant viruses lurking within other microbes. This viral awakening unleashes full-blown infections that destroy the virus-carrying cells, Howard Hughes Medical…
A microbial compound in the gut leads to anxious behaviors in mice — ScienceDaily
A Caltech-led team of researchers has discovered that a small-molecule metabolite, produced by bacteria that reside in the mouse gut, can travel to the brain and alter the function of…
When performing calculations, some neurons are active when adding, others when subtracting — ScienceDaily
The brain has neurons that fire specifically during certain mathematical operations. This is shown by a recent study conducted by the Universities of Tübingen and Bonn. The findings indicate that…
Enhanced nerve transmission seen in older adults who remained active — ScienceDaily
When elderly people stay active, their brains have more of a class of proteins that enhances the connections between neurons to maintain healthy cognition, a UC San Francisco study has…
No more annual flu shot? New target for universal influenza vaccine — ScienceDaily
Scientists at Scripps Research, University of Chicago and Icahn School of Medicine at Mount Sinai have identified a new Achilles’ heel of influenza virus, making progress in the quest for…
Shark antibody-like proteins neutralize COVID-19 virus, help prepare for future coronaviruses — ScienceDaily
Small, unique antibody-like proteins known as VNARs — derived from the immune systems of sharks — can prevent the virus that causes COVID-19, its variants, and related coronaviruses from infecting…
Can a dangerous microbe offer a new way to silence pain? Deadly anthrax toxin blocks multiple types of pain in mice, study shows — ScienceDaily
Anthrax has a scary reputation. Widely known to cause serious lung infections in humans and unsightly, albeit painless, skin lesions in livestock and people, the anthrax bacterium has even been…
Experimental mRNA HIV vaccine safe, shows promise in animals — ScienceDaily
An experimental HIV vaccine based on mRNA — the same platform technology used in two highly effective COVID-19 vaccines — shows promise in mice and non-human primates, according to scientists…
Synthetic tissue can repair hearts, muscles, and vocal cords — ScienceDaily
Combining knowledge of chemistry, physics, biology, and engineering, scientists from McGill University develop a biomaterial tough enough to repair the heart, muscles, and vocal cords, representing a major advance in…
After single injection, paralyzed animals regained ability to walk within four weeks — ScienceDaily
Northwestern University researchers have developed a new injectable therapy that harnesses “dancing molecules” to reverse paralysis and repair tissue after severe spinal cord injuries. In a new study, researchers administered…
