Researchers sequenced a region of the house finch genome, showing similarities to mammalian genomes in structure. The study found that birds' compact genomes favor metabolic demands related to flight, supporting shared basic genome structure with mammals.
A new study suggests that most gamma radiation reaching Earth is leftover energy from massive shock waves caused by gravitational forces. The collision of electrons with low-energy photons could be a sign of ordinary matter captured within intergalactic clouds, shedding light on the 'missing matter' puzzle.
A four-month study of over 200 ambulance arrivals found potential for injury to children and other occupants in urban medical centers. Researchers identified opportunities for prevention, including securing EMS equipment and ensuring proper restraint.
Researchers are developing cost-effective methods to capture and store carbon dioxide, with potential to reduce global warming impact. The DOE-funded projects include membrane development, vortex tube separation, and algae-based carbon sequestration.
Researchers create molecular footprints of information to encode diverse data, including music, on a single silicon surface. The novel approach enables precise control over structure and chemical composition of nano-devices, potentially leading to breakthrough electronic tools.
Researchers found that higher doses of electroconvulsive therapy (ECT) were more effective in relieving depression, with 66.7% of patients experiencing relief compared to 38.9% on lower doses. However, the high-dose group also experienced temporary memory disturbances and longer recovery times.
A door-to-door campaign in Auckland, New Zealand raised awareness of meningococcal disease among at-risk populations. The campaign, initiated in 1998, used lay educators to visit over 11,000 homes and deliver key messages about the disease.
Researchers at OHSU have discovered new synapses between nerve cells and oligodendrocytes, suggesting a key role in myelin formation. These connections may help answer questions about how nerve cells regulate myelin production, potentially leading to treatments for multiple sclerosis.
Researchers at the University of Southern California have discovered a unique nuclear DNA structure that helps elucidate the process of immunoglobulin class switching. This finding may provide insights into B cell cancer, such as Burkitt's lymphoma.
A recent study published in Heart journal has found that recreational cocaine use promotes the formation of blood clots, leading to an increased risk of heart attacks. The research, which monitored 14 young adults after they received a dose of cocaine, showed that even occasional use can have significant effects on cardiovascular health.
Biologists at UCSD discovered that the Argentine ant's ability to thrive in California is due to its low genetic diversity, which allows it to recognize and accept individuals from the same colony. This has led to the formation of a single, large 'supercolony' that dominates native species.
A new Ohio University study reveals that e-commerce has increased the value of used and rare books, with online sales accounting for a 12.5% increase in book sales. The study also found that prices for rare books have climbed, while common titles have seen stabilization or decrease in price.
Astronomers have found evidence of a supermassive black hole similar to the one in our Milky Way in a nearby galaxy. The discovery was made using spectra from the Hubble Space Telescope and reveals details about the object's mass that could help scientists understand how these celestial phenomena are formed.
A new study found that two to three drinks significantly affect mariners' performance, making it twice as long to correct system failures after consuming alcohol. The researchers recommend lowering the current blood alcohol concentration limit for commercial ship personnel to mitigate this risk.
A University of Pittsburgh researcher found that children exposed to lead have a significantly greater odds of developing delinquent behavior. The study showed that delinquent youths had significantly higher mean concentrations of lead in their bones compared to non-delinquent controls, with results true for both whites and African Ame...
A large UM study found that mycophenolate mofetil (MMF) reduces the risk of losing a transplanted kidney due to chronic failure better than azathioprine (AZA). MMF protects against kidney loss even when acute rejection prevention effects are eliminated, with nearly 86% of MMF-treated kidneys surviving four years.
Molecular geneticists have characterized gene mutations in families with pseudoxanthoma elasticum (PXE), a rare inherited disorder that can lead to blindness, early heart attacks, and cardiovascular disease. The study provides the basis for DNA-based carrier detection, prenatal testing, and improved diagnosis of the condition.
Researchers at Oregon State University have discovered a new class of chemicals called 'bruchins' that signal a plant to form a benign tumor, helping prevent insect infestation. The unusual chemical can induce tumor formation even at low levels, with precise effects on the plant.
A recent study found that a half-day safety program for kindergarten students showed minimal improvement in basic safety skills. The research compared two groups of children, one that participated in the program and another that did not, but found no significant difference in their scores. This suggests that many safety programs, like ...
Researchers have used new methods to track the evolution of human chromosomes over a 130 million-year period, finding that one chromosome is shared only with chimpanzees. By examining analogous chromosomes in other mammals, scientists can reconstruct how human chromosomes evolved from ancient origins.
