A young planet whirling around a petulant red dwarf star is changing in unpredictable ways orbit-by-orbit. It is so close to its parent star that it experiences a consistent, torrential blast of energy, which evaporates its hydrogen atmosphere — causing it to puff off the planet. But during one orbit observed with Hubble, the planet looked like it wasn't losing any material at all, while an orbit observed with Hubble a year and a half later showed clear signs of atmospheric loss.
UC San Diego Health is among the first in the nation to perform an experimental regenerative brain cell therapy for epilepsy aimed at eliminating seizures.
People who carry the gene variant associated with the strongest risk for Alzheimer’s disease may lose their ability to detect odors earlier than people who do not carry the gene variant, which may be an early sign of future memory and thinking problems, according to a study published in the July 26, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. The gene variant associated with this increased risk of Alzheimer’s is called APOE e4.
Taking more daily steps is associated improved health, including fewer symptoms and physical limitations, for people with heart failure, a new study finds.

Water, water, everywhere – not in drops, but as steam. Scientists using NASA’s James Webb Space Telescope have discovered that thirsty planets in the PDS 70 system have access to a reservoir of water. Importantly, the water vapor was found within 100 million miles of the star – the region where terrestrial planets like Earth may be forming. (The Earth orbits 93 million miles from our Sun.)
A technique that uses imaging technology as a guide can make radiation therapy safer for patients with prostate cancer by helping clinicians accurately aim radiation beams at the prostate while avoiding nearby tissue in the bladder, urethra, and rectum.
More than 1.4 million times a year, people with Alzheimer’s disease and other forms of dementia end up in emergency care, making up nearly 7% of all emergency visits for any reason by people over age 65, a new study shows. Compared with their peers who don’t have dementia, these patients have twice the rate of seeking emergency care after an accident or a behavioral or mental health crisis.
In a new study published in JMIRx Bio, one of JMIR Publications’ new overlay journals, scientist Floe Foxon explores whether the Loch Ness Monster, a creature in Scottish folklore, could be a giant eel. Using previous estimates of the monster’s size to predict the probability of encountering a large eel of a similar size, the study found that giant eels could not account for sightings of larger animals in Loch Ness, a freshwater lake in the Scottish Highlands.
According to an analysis of the UK’s cosmetic injectables industry by UCL researchers, 68% of cosmetic practitioners who are administering injections such as Botox are not qualified medical doctors.

Fathers’ as well as mothers’ psychiatric history is associated with preterm birth, according to a study published July 20th in the open access journal PLOS Medicine. The research shows for the first time that the risk of preterm birth is higher in infants whose fathers or mothers have psychiatric diagnoses, compared with those who do not, and where both parents have diagnoses, the risk is increased again.
A Hubble Space Telescope image of the asteroid Dimorphos, taken on December 19, 2022, nearly three months after the asteroid was impacted by NASA's DART mission. Hubble's sensitivity reveals a few dozen boulders knocked off the asteroid by the force of the collision. The boulders range in size from three feet to 22 feet across, based on Hubble brightness measurements. They are drifting away from the asteroid at little more than a half-mile per hour.
The majority of older adults with cognitive impairment are still driving, despite concerns raised by caregivers and others, a study finds. Researchers say it’s best for caregivers to start conversations surrounding driving earlier while the care recipient is able to understand and actively participate in the discussion.
