NASA’s James Webb Space Telescope recently observed Uranus, and the resulting image highlights a complex system of rings as well as a bright polar cap and likely storm clouds.
Hubble observed a curious linear feature that was first dismissed as an imaging artifact from the telescope’s cameras. But follow-up observations indicate it is a 200,000-light-year-long chain of young blue stars created in the wake of a runaway black hole.
A new study from UCLA researchers finds sex-specific brain signals that appear to confirm that different drivers lead men and women to develop obesity.
A group of physicians and scientists with the University of Miami Miller School of Medicine are releasing an important study that will be published in the journal Pediatrics on Thursday, showing that COVID-19 can cross into the placenta of pregnant women and cause brain injury in newborns, as evidenced with 2 cases they treated here in Miami. One of the infants also died at about 13 months old. Further testing of the infant’s brain specimen showed that the virus was still present in the brain at the time of death—which was over a year after birth.
Researchers have shown that, in two cases, COVID-19 infection breached the placenta and caused brain damage in the newborn.
People who have sleep problems may be more likely to have a stroke, according to a study published in the April 5, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. Sleep problems included getting too much or too little sleep, taking long naps, having poor quality sleep, snoring, snorting and sleep apnea. In addition, those who had five or more of these symptoms had an even greater risk of stroke. The study does not show that sleeping problems cause stroke. It only shows an association.

Hubble has found a rare pair of quasars inside two merging galaxies. These brilliant beacons are powered by supermassive black holes. The galaxies will eventually merge—and so will the quasars. This will result in an even more powerful black hole.
Lonely individuals’ neural responses differ from those of other people, suggesting that seeing the world differently may be a risk factor for loneliness regardless of friendships.
The dynamics and availability of soil nutrients affects the growth of plants and microbes and how ecosystems respond to changing environmental conditions. Researchers investigated climate impacts on peat nutrient availability as part of the large-scale Spruce and Peatland Responses Under Changing Environments (SPRUCE). The experiment found that above- and below-ground warming exponentially increased the availability of nutrients throughout below-ground peat layers. However, elevated carbon dioxide did not affect the availability of nutrients.
As more consumers turn to the newly available ChatGPT for health advice, researchers are eager to see whether the information provided by the artificial intelligence chatbot is reliable and accurate. A new study conducted by researchers at the University of Maryland School of Medicine (UMSOM) indicates that the answers generated provide correct information the vast majority of the time; sometimes, though, the information is inaccurate or even fictitious. Findings were published today in the journal Radiology.

Studying the electronic structure of actinide elements can help advance the future of nuclear materials. A new study of several plutonium hybrid materials found that the bonds between these elements were predominantly ionic but also involved covalent bonding associated with the 5f electron shell. This research contributes to the collective goal of resolving the f-electron challenge, the goal of the Department of Energy Office of Science’s Heavy Element Chemistry program.
Acting as a giant touch-free thermometer, NASA’s James Webb Space Telescope has successfully measured heat radiating from the innermost of the seven rocky planets orbiting TRAPPIST-1, a cool red dwarf star 40 light-years from Earth. With a dayside temperature of 450 degrees Fahrenheit, the planet is just about perfect for baking pizza. But with no atmosphere to speak of, it may not be the best spot to dine out. The result is the first from a comprehensive set of Webb studies of the TRAPPIST-1 system, and marks an important step in determining whether planets orbiting tiny but violent red dwarfs, the most common type of star in the Galaxy, can sustain atmospheres needed to support life.
