Living cells may generate electricity through the natural motion of their membranes. These fast electrical signals could play a role in how cells communicate and sense their surroundings. Scientists have proposed a new theoretical explanation for how living cells may generate electrical signals on their own. The idea centers on the cell membrane, the [...]
Researchers identify a shared RNA-protein interaction that could lead to broad-spectrum antiviral treatments for enteroviruses. A new study from the University of Maryland, Baltimore County (UMBC), published in Nature Communications, explains how enteroviruses begin reproducing inside human cells. These viruses include those responsible for polio, encephalitis, myocarditis, and the common cold, and they start infection [...]
Stimulating the liver to produce some of the signals of the thymus can reverse age-related declines in T-cell populations and enhance response to vaccination. As people age, their immune system function declines. T cell populations become smaller and can’t react to pathogens as quickly, making people more susceptible to a variety of infections. To [...]
A single nerve injury can quietly reshape the immune system across the entire body. Preclinical research from McGill University suggests that nerve injuries may lead to long-lasting changes in the immune system, and these effects appear to differ between males and females. Nerve damage is relatively common and can result from stretching, pressure, or [...]
New research reveals organized networks linking paper mills, intermediaries, and compromised academic journals Organized scientific fraud is becoming increasingly common, ranging from fabricated research to the buying and selling of authorship and citations, according to a new study from Northwestern University. The researchers conducted an in-depth examination of scientific misconduct by pairing large-scale analyses of [...]
Scientists can finally hear the brain’s quietest messages—unlocking the hidden code behind how neurons think, decide, and remember. Scientists have created a new protein that can capture the incoming chemical signals received by brain cells, not just the signals they send out. These incoming messages are carried by glutamate, a neurotransmitter that plays a central role [...]
A new study analyzing the immune response to COVID-19 in a Catalan cohort of health workers sheds light on an important question: does it matter whether a person was first infected or first vaccinated? According to the results, the order of the events does alter the outcome, at least when it comes to long-term [...]
As claims about conscious AI grow louder, a Cambridge philosopher argues that we lack the evidence to know whether machines can truly be conscious, let alone morally significant. A philosopher at the University of Cambridge says we currently have too little reliable evidence about what consciousness is to judge whether artificial intelligence has crossed that threshold. Because [...]
Using AI, researchers identified one tiny molecular interaction that viruses need to infect cells. Disrupting it stopped the virus before infection could begin. Washington State University scientists have uncovered a method to interfere with a key viral protein, stopping viruses from getting inside cells where they can cause disease. The discovery points toward a possible new [...]
A deadly, drug-resistant hospital fungus may finally have a weakness—and scientists think they’ve found it. Researchers have identified a genetic process that could open the door to new treatments for a dangerous fungal infection that has repeatedly forced hospital intensive care units to close. The discovery offers fresh hope against a pathogen that has [...]
