Influenza A virus particles strategically adapt their shape—to become either spheres or larger filaments—to favor their ability to infect cells depending on environmental conditions, according to a new study from National Institutes of Health (NIH) scientists. This previously unrecognized response could help explain how influenza A and other viruses persist in populations, evade immune responses, and acquire adaptive mutations, the researchers explain in a new study published in Nature Microbiology.
SARS-CoV-2 infection linked to more rapid plaque growth in lesions
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is associated with more rapid progression of coronary artery lesion-based plaque volume, according to a study published online Feb. 4 in Radiology.
Inflammation-triggering cellular pathway identified as potential new drug target for Alzheimer’s disease
A team of researchers from the Keck School of Medicine of USC has unlocked the details of a cellular pathway that triggers cellular inflammation and aging and is linked to Alzheimer’s disease, particularly among those who carry the APOE4 genetic risk. They have also found a way to return cells to a healthy state, revealing a new potential approach to treatment.
What do the changes to IUD access mean for Australian women?
Ahead of the government’s response this week to a Senate inquiry into access to reproductive health care in Australia, the government has announced new measures to make it easier to get an intrauterine device, or IUD.
What you need to know about the new implants to patch up failing hearts. Are they really a ‘breakthrough’?
There are many difficulties in converting any biological research into a medicine that will treat patients. Because of the complexity involved, these difficulties apply especially to translating cell research in the laboratory to a successful treatment for heart failure, where the heart is unable to pump blood around the body properly.
Advanced imaging and AI reveal smoking-related toxins in placenta samples
Rice University scientists and collaborators at Baylor College of Medicine (BCM) have demonstrated a new method for detecting the presence of dangerous chemicals from tobacco smoke in human placenta with unprecedented speed and precision.
Perception of trustworthiness may drive brain’s safety and alarm signals
Perceiving whether another person is a personal health risk requires quickly assessing their trustworthiness. With limited characteristics available, implicit assumptions often influence risk perception.
Cerebellar serotonin offers potential new strategy for relieving anxiety
Understanding the neural circuits that drive anxiety may help researchers discover circuit-specific targets and therefore increase the precision of treatment strategies. Previous studies have separately suggested that increased serotonin levels and the cerebellum may play roles in anxiety.
Fertility tracking has increased in some states post-Dobbs
The use of fertility-tracking technology increased in some states after the U.S. Supreme Court overturned Roe v. Wade despite warnings that reproduction-related data might not be secure, a new study has found.
Looking for a sperm donor online? Four things to think about first
People looking for a sperm donor can go to a fertility clinic, ask a friend to donate or look for a donor online, including on an app or via social media.
