Astronomers have discovered a highly turbulent galaxy that may soon lose its supply of star-forming gas due to violent motion. The galaxy, W2246-0526, is an obscured quasar with a supermassive black hole at its center, causing intense radiation that exerts pressure on the entire galaxy.
African trypanosomes use nanotubes to sense their environment and respond to it, as well as release extracellular vesicles that can cause anemia in humans. The discovery could lead to improved therapies for sleeping sickness, a disease fatal if left untreated and threatening millions of people annually.
A recent study published in JAMDA found that nearly half of hospital readmissions from post-acute care facilities occur within 14 days, and patients who experience readmission have a higher mortality rate. The researchers also identified the need for invasive devices and advanced care as contributing factors to readmissions.
Scientists at The Wistar Institute discovered that p53 can suppress accumulated DNA damage at telomeres, preserving genome integrity. This finding highlights a new benefit of the vital gene p53 in protecting against cancer.
Researchers found that different color patches on butterfly wings are controlled by independent genetic switches, which can be mixed and matched between species to create new patterns. This phenomenon allows butterflies to share common warning signs with predators, a form of mimicry.
Researchers at FAU have discovered that mother-of-pearl is formed through the aggregation of nanoparticles within an organic matrix, rather than crystallisation. This unique process, found in nature, has implications for developing new high-performance ceramics with improved mechanical properties.
Researchers at the University of Southampton found that bone marrow lesions on MRI scans can predict more rapid progression of osteoarthritis. Individuals with BMLs had a loss rate of 0.10mm per year faster than those without, potentially leading to earlier need for joint replacement.
Researchers used ALMA to study W2246-0526, the most luminous galaxy known, finding it's ejecting its star-forming gas due to intense infrared radiation. This turbulence could lead to the galaxy evolving into a traditional quasar.
The grant will explore various dosing regimens of daptomycin, a lipopeptide antibiotic, to treat vancomycin-resistant Enterococcus faecium (VREfm) bacteria. The research aims to prevent resistance development and improve treatment outcomes for patients with life-threatening infections.
A three-year study aims to determine the effectiveness of a comprehensive lifestyle intervention in reducing cardiovascular disease risk factors. Participants will receive personalized counseling and monitoring, while others will receive standard occupational health care.
A team of researchers tracked a rare 66-million-year-old tyrannosaur footprint trail in Wyoming, shedding new light on the dinosaur's speed and hunting habits. The study suggests that even young tyrannosaurs were capable of rapid movement, challenging previous theories about their sluggish nature.
Cancer rates vary significantly among Asian American/Native Hawaiian/Pacific Islander populations, with Samoan men having the highest lung cancer rates and Laotian men having the highest liver cancer rates. Breast cancer mortality rates have decreased among AANHPI women combined, while liver cancer death rates declined among AANHPI males.
A new Anglo-French research project will give a voice to French children who became displaced during WWII, shedding light on their experiences and challenges. Dr. Lindsey Dodd's project aims to disrupt the established narrative of the period, which often focuses on resistance and collaboration.
Researchers at Wake Forest Baptist Medical Center found an association between obesity and the formation of blood clots in children and adolescents. Obesity was a statistically significant predictor of blood clot formation in juveniles, contributing to increased incidence of pediatric venous thromboembolism.
Researchers found that high-challenge activities improved memory performance and brain activity efficiency in older adults. The study suggests that mentally demanding activities may be neuroprotective and essential for maintaining a healthy brain into late adulthood. Enhanced neural efficiency was maintained a year after participation.
Researchers used cactus species to test whether regions variable across closely related species show predictable intraspecific variability. The study found that rate-heterogeneity poses a practical challenge for researchers, and screening steps are necessary to discover regions of the genome with sufficient variability.
