Glucagon, a hormone involved in regulating appetite, loses its ability to help obese people feel full after a meal, but it continues to suppress hunger pangs in people with type 1 diabetes, according to a recent study.
Women diagnosed with gestational diabetes are nearly seven times more likely to have obstructive sleep apnea than other pregnant women, according to a recent study.
People with severe encephalitis — inflammation of the brain — are much more likely to die if they develop severe swelling in the brain, intractable seizures or low blood platelet counts, regardless of the cause of their illness, according to new research.
A healthy ear is much better at detecting and transmitting sound than even the most advanced hearing aid. But now researchers have uncovered new insights into how the ear -- in particular, the cochlea -- processes and amplifies sound. The findings could be used for the development of better devices to improve hearing.
During ground take-off/landing maneouvres, aircraft landing gear can display unwanted oscillations, which are referred to as shimmy oscillations. Scientist are studying the dynamics of aircraft landing gear using nonlinear models.
A new three-in-one optical element can control light's amplitude, phase, and polarization through a wedding of old-fashioned holograms and state-of-the-art nanoscale features....
Conventional thinking holds that Alzheimer's disease is likely caused by one of two proteins, one called tau, the other beta-amyloid. Now a new study suggests a third possible cause -- an accumulation of iron that destroys cell function.
People usually feel good when they make a charitable donation, but they feel even better if they make the donation directly to someone they know or in a way that builds social connection. New research investigates for the first time how social connection helps turn generous behavior into positive feelings on the part of the donor.
Platinum is a key material in dye-sensitized solar cells, where it is used to make counter electrodes. A new, 3-D form of graphene made from carbon monoxide and lithium oxide was used to replace the platinum with virtually no loss in electrical generating capacity.
A computer simulation has revealed the epic, ocean-spanning journeys traveled by millimeter-sized coral larvae through the world's seas. The model is the first to recreate the oceanic paths along which corals disperse globally, and will eventually aid predictions of how coral reef distributions may shift with climate change.
