Researchers identify genetic abnormalities in microsatelite instability (MSI) and chromosomal instability (CSI) leading to varying tumor behaviors. Colorectal cancer patients with MSI form have a better chance of surviving longer, prompting potential changes in treatment strategies.
A new report describes four patients who experienced bruxism, including jaw clenching, headaches, tooth grinding, and broken teeth, after taking Zoloft for depression and anxiety. The symptoms resolved with the addition of another anti-anxiety drug, Buspar.
Physicians at UNC-CH and Duke will receive funding to support care for people living with AIDS across North Carolina and clinical trials promising further medical progress. The renewed national Adult AIDS Clinical Trials Group (AACTG) funding reflects the quality of AIDS research and treatment in North Carolina.
Scientists confirmed the presence of oxygen VI in the galactic halo, indicating extremely high temperatures approaching half a million degrees Fahrenheit. The discovery provides strong evidence for supernovas pumping hot gas into the corona, supporting a long-held hypothesis about the galaxy's recycling process.
Poultry farmers can stop using antibiotics to promote growth in birds by adding antibodies against appetite-suppressing neurotransmitters and a fatty acid found in hamburgers. This alternative method produces similar growth gains as antibiotics, with improvements of 3-5% in growth rates.
Researchers from the University of Washington have discovered that Barnard's Galaxy, an irregular dwarf galaxy, is significantly different from the Milky Way. Using images taken by the Hubble Space Telescope, they found three star clusters within NGC 6822 to be of very different ages, with one cluster dating back 15 billion years.
A new AI system, CONSA, helps bickering computer programs resolve differences and come up with a satisfactory result. The system has been successfully tested on agent-controlled robot football teams and helicopter combat simulations.
A new NASA satellite has provided unprecedented sensitivity to detect molecular hydrogen, the primary ingredient for star and planet formation. This discovery suggests that star formation proceeds similarly across various space environments, including nearby galaxies.
Research by Australian scientist Peter Dingle found that potted plants have a limited effect on reducing formaldehyde levels, a toxic chemical linked to sick building syndrome. While plants can improve the aesthetic environment, they do not significantly clean the air of pollutants.
Researchers created a virtual crash test dummy to predict head and chest injuries during accidents. The simulation shows that multiple impacts result in more severe injuries, regardless of the vehicle model involved.
Astronomers have observed five young, massive star clusters in a distant galaxy, offering a glimpse into the earliest stages of stellar nursery development. The discoveries, estimated to be around 500,000 years old, provide valuable insights into how globular clusters form and evolve over billions of years.
Researchers at the Mayo Clinic found that an experimental diode laser treatment controlled cancer growth in all but one patient with melanoma in the eye. No recurrences were noted in the remaining patients during follow-up periods.
Researchers at UT Southwestern Medical Center have developed a new antibiotic solution that may help prevent capsular contracture, a common risk associated with breast implant surgery. The solution, created by Dr. William P. Adams Jr., inhibits bacterial growth from organisms commonly found around implants and has shown promise in prev...
Scientists at National Jewish Health have identified a key protein that regulates fat cell development, which could lead to new strategies for treating obesity and related conditions. By inserting a negative version of CREB into fat cells, researchers can inhibit the growth of new fat cells.
Scientists from the University of Wisconsin-Madison have developed a new surface chemistry that simplifies DNA computing and enables scaling up to tackle complex problems. This breakthrough demonstrates DNA computing's potential to surpass conventional computers in information storage and processing capabilities.
A recent study from the Mayo Clinic found that eating disorders continue to increase in young females, with a steady rise in incidence over the past 50 years. The study suggests that the type of eating disorder being reported is shifting towards more cases of bulimia (binge and purge).
A Yale researcher has discovered up to 70 new and very distant RR Lyrae stars in the Milky Way that can provide valuable clues about the galaxy's history and composition. The stars are thought to be among the oldest in the galaxy, with ages of over 12 billion years.
