Researchers develop biomimetic gel that binds to glucose molecules, potentially triggering insulin release in diabetics. The gel's sensing mechanism could be incorporated into implantable devices, providing therapy for type one diabetes.
Researchers are collecting data on the behavior of Puget Sound's orca whales using novel tools such as a small radio-controlled catamaran and a fish finder. The study suggests that the whales are declining due to a drop in salmon runs and increasing contamination from PCBs.
Researchers have found that an enzyme mimetic compound significantly improves the functioning of blood vessels and nerves in diabetic animal studies, reducing vascular abnormalities and nerve damage. The study suggests a potentially significant new approach for treating and preventing complications associated with diabetes.
UCSF researchers identified eight essential dimensions for evaluating nursing home quality. These categories include care, safety, and resident rights. The streamlined system aims to simplify inspections and provide more accurate information for consumers.
A new study by Charles G. Go, Ph.D., and Paula Cupertino, Ph.D. found that adolescents who engage in delinquent behaviors are more likely to contemplate suicide. The study surveyed over 1,200 middle school students in Oakland, California, and found that those who contemplated suicide also reported the most delinquency.
A meta-analysis of studies on risk factors for unsafe driving found that cognitive processing speed is the most accurate measure of older drivers' abilities. This metric can be improved through speed of processing training, enhancing driving skills and safety.
A new study found that Saharan dust clouds traveling thousands of miles can lead to massive toxic algae blooms in the Gulf of Mexico. The research used satellite and ground-based measurements to track dust clouds, which increased iron concentrations by 300% and triggered a huge bloom of toxic red algae.
Neuroscientists identified brain regions activated by eating chocolate's rewarding and aversive aspects, offering insights into addiction and eating disorders. The study provides a novel model for understanding addiction using primary reinforcers like fat and sweet.
A team of researchers has developed a novel treatment for spinal cord injuries using a plastic tube filled with chemicals that promote nerve growth. The tube, designed to mimic the flexibility of the spinal cord, provides a pathway for neurons to grow and potentially reconnect severed nerves.
Researchers at Virginia Tech are developing a 'prodrug' to deliver neuroprotective compounds to the brain, overcoming limited solubility issues. The approach aims to inhibit monoamine oxidases and neuronal nitric oxide synthase enzymes involved in Parkinson's disease.
A new study found that wood smoke is toxic to certain aquatic organisms in the Great Lakes region. The researchers collected particulate matter samples from different areas along the shores of southern Lake Michigan and found concentrations as low as 10-15 milligrams per liter killed 50% of water fleas within a 24-hour exposure.
Researchers at Cornell University have created hybrid materials that mimic and improve on the properties of natural silkworm silk. The new materials, which include extreme flexibility, considerable tensile strength, and water solubility, are poised to be used in a variety of applications including textiles and biomedical fields.
Researchers found that low-energy radio waves can kill zebra mussels by depleting calcium levels in the water, which are essential for their survival. This method is considered an eco-friendly alternative to traditional chemical treatments or molluscicides, and may be effective in preventing pipe clogging.
Researchers found that store-bought tofu, soy cheese, and soy drinks contain significant levels of oxalate, which can bind with calcium in the kidneys to form kidney stones. The American Dietetic Association recommends limiting oxalate intake to 10 milligrams per serving for patients with a history of kidney stones.
Paul McEuen's research group has developed a method to count individual electrons in carbon nanotubes using an atomic force microscope. This breakthrough enables scientists to study the basic physics of electron behavior and advance the field of nanoelectronics.
Researchers have discovered colchicine, a toxic substance, in the blood of human placentas, raising concerns about its potential impact on pregnancy. Expectant mothers should avoid taking Gingko biloba supplements due to the risk of complications.
A new study found that implanted cardioverter defibrillators save the most lives among patients with severe heart disease who suffer from abrupt heart rhythm malfunctions. The device monitors electrical signals and acts within seconds to restore a normal heartbeat, providing life-saving benefits for high-risk patients.
A new bar coding system developed by Purdue University chemists can quickly identify the most biologically active compounds among thousands of candidates. The method uses standard spectrometers and reduces the laborious process to a few hours, cutting down time needed to identify active compounds to zero.
Researchers aim to identify and evaluate variations in 95 genes involved in cancer treatment, using DNA tests to predict a drug's effect on an individual. The goal is to tailor chemotherapy to each patient, improving treatment outcomes.
