Medical Xpress / Gut microbes bolster immunity in HIV patients, research reveals
The circumstances surrounding a study on a deadly virus could hardly have been more dramatic. One of its first authors was forced to flee his homeland when it became a war zone. More than 2,000 kilometers away, the laboratory ...
Phys.org / Captured on camera for the first time: How tiny marsupials crawl to their mother's pouch
For the first time, scientists have recorded how baby dunnarts, tiny carnivorous marsupials from Australia, reach their mother's pouch not long after being born. While much is known about how many other marsupial babies go ...
Phys.org / mRNA fragments reveal a hidden process that protects cells from harmful mutations
Some genetic mutations that are expected to completely stop a gene from working surprisingly cause only mild or even no symptoms. Researchers in previous studies have discovered one reason why: cells can ramp up the activity ...
Phys.org / White-nose syndrome puzzle solved: Biological mechanisms behind devastating bat disease revealed
Millions of bats in North America have died from white-nose syndrome, and a new study from the University of Waterloo explores why and how the fungal disease has devastated bat populations on this continent, while it has ...
Phys.org / Plants retain a 'genetic memory' of past population crashes, study shows
Researchers at McGill University and the United States Forest Service have found that plants living in areas where human activity has caused population crashes carry long-lasting genetic traces of that history, such as reduced ...
Medical Xpress / Exercise may train the brain to build endurance via SF1 neuron activity
Exercise does more than strengthen muscles; it also rewires the brain. In a study published in Neuron, researchers reveal that the lasting gain in endurance from repeated exercise—such as the ability to run farther and ...
Phys.org / How plants balance woody xylem and fleshy tissues: Thermospermine targets methylated ribosomes
Scientists have identified a crucial mechanism that allows plants to shape their vascular systems, determining whether they grow soft edible storage organs or develop the rigid woody tissue characteristic of trees. Published ...
Medical Xpress / Exposure to intense wildfire smoke during pregnancy may be linked to increased likelihood of autism
New research suggests that exposure to intense wildfire smoke during pregnancy may be associated with an increased likelihood of autism in children. The study of more than 8.6 million births in California is the largest to ...
Phys.org / Exploring how the Gulf Stream affects the climate system and the carbon cycle
It is well documented that the Gulf Stream plays a pivotal role in the climate system through its transfer of heat, which ultimately supplies warmth to northern latitudes in the North Atlantic. What remains less well understood ...
Medical Xpress / A glaucoma drug may help prevent opioid relapse
An existing drug currently used to treat glaucoma, altitude sickness, and seizures may also have the potential to prevent relapse in opioid use disorder, according to a study by researchers at University of Iowa Health Care. ...
Phys.org / New record of great white shark in Spain sparks a 160-year review
On April 20, 2023, a juvenile great white shark (Carcharodon carcharias) measuring approximately 210 cm and weighing between 80 and 90 kg was incidentally caught by local fishermen off the coast of the eastern peninsula within ...
Medical Xpress / As nights warm, study flags possible prenatal link to autism risk
Higher nighttime temperatures during pregnancy may be associated with a higher risk of autism diagnosis in children, according to a new study led by researchers at Tulane University. The research examined nearly 295,000 mother–child ...
