COVID-19 can kill heart muscle cells, interfere with contraction
A new study provides evidence that COVID-19 patients' heart damage is caused by the virus invading and replicating inside heart muscle cells, leading to cell death and interfering with heart muscle contraction. The researchers used stem cells to engi.....»»
Unruly Gut Fungi Can Make Your Covid Worse
An infection can upset your microbiome, and if certain gut fungi run riot, this can kick the immune system into overdrive......»»
Online schooling is not just for lockdowns. Could it work for your child?

Why zebrafish can regenerate damaged heart tissue, while other fish species cannot
A heart attack will leave a permanent scar on a human heart, yet other animals, including some fish and amphibians, can clear cardiac scar tissue and regrow damaged muscle as adults......»»
"Green muscle memory" and climate education promote behavior change: Report
This year, organizers of Earth Day are calling for widespread climate education as a critical step in the fight against climate change......»»
Light show in living cells: New method allows simultaneous fluorescent labeling of many proteins
Observing proteins precisely within cells is extremely important for many branches of research but has been a significant technical challenge—especially in living cells, as the required fluorescent labeling had to be individually attached to each p.....»»
Key protein regulates immune response to viruses in mammal cells
Researchers have revealed the regulatory mechanism of a specific protein that plays a key role in balancing the immune response triggered by viral infections in mammal cells. These findings could help drive the development of antiviral therapies and.....»»
Coal train pollution increases health risks and disparities, research warns
Trains carrying loads of coal bring with them higher rates of asthma, heart disease, hospitalization and death for residents living nearest the rail lines, according to a new study from the University of California, Davis......»»
Researchers crack mystery of swirling vortexes in egg cells
Egg cells are the largest single cells on the planet. Their size—often several to hundreds of times the size of a typical cell—allows them to grow into entire organisms, but it also makes it difficult to transport nutrients and other molecules ar.....»»
Mobile genetic elements can inadvertently suppress bacterial immune systems, research reveals
Bacterial restriction-modification systems are responsible for protecting cells from foreign genetic material, for example, bacteriophages and plasmids. Immune systems require strict regulation, as bacteria, like humans, can have autoimmune reactions.....»»

Saturn"s ocean moon Enceladus could support life—researchers are working out how to detect extraterrestrial cells there
Saturn has 146 confirmed moons—more than any other planet in the solar system—but one called Enceladus stands out. It appears to have the ingredients for life......»»
Studying spaceflight atrophy with machine learning
Even intense exercise by astronauts cannot compensate for muscle atrophy caused by microgravity. Atrophy occurs, in part, by way of an underlying mechanism that regulates calcium uptake. Recent research has shown exposure to spaceflight alters the up.....»»
