Tracing how the infant brain responds to touch with near-infrared spectroscopy
2023-12-09
Tokyo, Japan – Researchers from Tokyo Metropolitan University have measured how oxygenated hemoglobin levels in the blood change in infants’ brains in response to touch. Using spectroscopy methods with external sensors placed on the scalp of sleeping infants, they found that the time at which levels peak doesn’t change with infant age, but the amount by which it varies over time does. Insights like this shed light on how the physiology of infants develop.

When is an aurora not an aurora?
2023-12-08
The shimmering green, red and purple curtains of the northern and southern lights — the auroras — may be the best-known phenomena lighting up the nighttime sky, but the most mysterious are the mauve and white streaks called Steve and their frequent companion, a glowing green "picket fence."
First recognized in 2018 as distinct from the common auroras, Steve — a tongue-in-cheek reference to the benign name given a scary hedge in a 2006 children's movie — and its associated picket fence were nevertheless thought to be caused by the same physical processes. But scientists were left scratching their heads about how these glowing emissions ...

USF Health Heart Institute doctors are upbeat about cardiac regeneration
2023-12-08
But when those batteries – heart muscle cells called cardiomyocytes − short circuit and die, the damage can be devastating. The damage to the heart muscle is usually permanent, leaving the heart unable to pump the way it should.
That’s the subject of a new study by a team that includes two USF Health doctors who reported their findings in Circulation, the flagship journal of the American Heart Association.
“An injury like a heart attack creates a massive loss of cardiomyocytes, and you can’t renew them,’’ said Da-Zhi Wang, PhD, director of the Center for Regenerative Medicine in the USF Health Heart Institute and Morsani College ...

Study reveals Zika’s shape-shifting machinery—and a possible vulnerability
2023-12-08
Viruses have limited genetic material—and few proteins—so all the pieces must work extra hard. Zika is a great example; the virus only produces 10 proteins. Now, in a study published in the journal PLOS Pathogens, researchers at Sanford Burnham Prebys have shown how the virus does so much with so little and may have identified a therapeutic vulnerability.
In the study, the research team showed that Zika’s enzyme—NS2B-NS3—is a multipurpose tool with two essential functions: breaking up proteins (a protease) and dividing its own double-stranded RNA into single strands (a helicase).
“We found that Zika’s ...

A dynamic picture of how we respond to high or low oxygen levels
2023-12-08
SAN FRANCISCO—December 8, 2023—It only takes holding your breath for slightly too long to understand that too little oxygen is bad for you. But can you also have too much? Indeed, breathing air with a higher oxygen level than your body needs can cause health problems or even death.
But with scant research on the topic, scientists have known little about how the body senses too much oxygen. Now, a new study from Gladstone Institutes has greatly expanded the scientific body of knowledge about the mechanisms at play, and why it matters for health.
Their findings, reported in the journal Science Advances, explain how breathing air with different levels of ...
