Extinct marine creatures hidden in Thai sanctuary
In Physics of Fluids, scientists demonstrate how bloodstains can yield valuable details by examining the protrusions that deviate from the boundaries of otherwise elliptical bloodstains. The researchers studied how these “tails” are formed using a series of high-speed experiments with human blood droplets less than a millimeter wide impacting horizontal surfaces at various angles. They found that the tail length can reflect information about the size, impact speed, and impact angle of the blood drop that formed the stain.
Children who had preexisting health problems or who lived in the Southern United States had a higher risk for severe health outcomes from acute COVID-19 infections, according to researchers at UT Southwestern Medical Center. The results, reported in the journal Hospital Pediatrics that is published by the American Academy of Pediatrics, also showed the importance of vaccinations in reducing the severity of illness for those who became infected.

With the rise of new drugs that can target the amyloid-beta plaques in the brain that are an early sign of Alzheimer’s disease, new ways are needed to determine whether memory loss and thinking problems are due to Alzheimer’s disease or another neurodegenerative disorder. A new study published in the November 15, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology, shows that shrinkage in the hippocampus area of the brain is associated with cognitive decline, even in people who don’t have amyloid plaques in the brain. The hippocampus plays a role in memory.
Through the Infant Development Project, researchers from the Beckman Institute for Advanced Science and Technology in the Interdisciplinary Lab for Social Development explored how early brain activity relates to the flexibility of infants’ social interactions and their ability to recover from stress.
A team at the University of Washington has created an interactive dashboard called WhaleVis, which lets users map data on global whale catches and whaling routes from 1880 to 1986. Scientists can compare this historical data and its trends with current information to better understand whale populations over time.
In 2008 NASA’s Spitzer Space Telescope found a protoplanetary disk unlike any other. The dusty disk of gas surrounding the young Sun-like star SZ Chamaeleontis (SZ Cha) was being pummeled by extreme ultraviolet radiation – something previously seen only in computer models, never in the real universe. Planets in this system would have more time to form than in a disk being evaporated by X-rays, which is the norm. However, when the James Webb Space Telescope followed up on SZ Cha, it found nothing out of the ordinary – no abundance of ultraviolet radiation. In a short space of cosmic time, conditions in SZ Cha’s disk had changed, leaving astronomers to untangle meaning from the mismatched data and its implications for the formation of other solar systems.
Genomic surveillance of AMR pathogens has the potential to revolutionize AMR control, but barriers such as lack of resources and training need to be overcome.
