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.
