Today's Top Stories
Gene variation linked to sugar
A recent study offers the first evidence of the role that a variation in the GLUT2 gene has on sugar intake, and may help explain individual preferences for foods high in sugar.Marijuana abuse and stroke
Long-term harmful effects of marijuana include risk for heart attacks and strokes in addition to impaired learning and memory.Are anxiety disorders mental?
Scientists were able to detect biochemical differences in the brains of individuals with generalised social anxiety disorder, proving a biological cause for the dysfunction.
Pharmacology
Relaxing with marijuana
A variety of middle-class people are making a conscious but careful choice to use marijuana to enhance their leisure activities, a study shows.Arsenic-based therapy
A tumour suppressor protein known as PML appears to be the factor that enables LICs to maintain their quiescence, suggesting that inhibition is a promising target.Antibiotic reduces cell death
Researchers have discovered how an antibiotic works to modulate the activity of a neurotransmitter that regulates brain functions.
Nanotechnology
Integrating nanowire devices
Scientists have developed a new technique for fabricating nanowire photonic and electronic integrated circuits that may one day be suitable for high-volume commercial production.Nanoworms target tumours
Scientists have developed "nanoworms" that travels through the bloodstream without significant interference and act like tiny anti-cancer missiles.Nanotube production advance
Researchers have found a way of producing carbon nanotubes in which they instantly form a highly sensitive ready made electric circuit.
Methods & Systems
Model sheds dementia light
A minor, seemingly inconsequential mutation results in unexpected changes in a very delicate chemical balance, creating build-up of the toxic by-products.Animal models hurts study
Research on traumatic spinal cord injuries is hampered by a reliance on animal experiments that don't accurately predict human outcomes, says a new study.Viral genome sequencing
Most emerging health threats are of zoonotic origin. For the overwhelming majority, their causative agents are RNA viruses which include but are not limited to HIV, SARS, Ebola, and Dengue.
Biotechnology
Ionic interaction studied
Researchers studied how biologically important, positively charged ions (cations) interact with negatively charged groups found in proteins (anions) to form salts.Controlling insulin and fat
A receptor called ALK7 plays important roles in the regulation of body fat deposition as well as the release of insulin from beta-cells in the pancreas.Ancient protein offers clues
A discovery suggests that a tiny motor protein is much more important than previously thought - and may even hold a key to understanding potentially fatal conditions.
Genetics
Causative gene for Alzheimer's
The genetic profile of two large Georgia families with high rates of late-onset Alzheimer's disease points to a gene that may cause the disease, researchers say.Glypican-3 gene function
Researchers have discovered how the loss of the GPC3 gene induces overgrowth through certain growth factors that stimulate cancer growth.Batten disease promise
Gene therapy is both safe and effective at slowing the progression of Batten disease, or Late Infantile Neuronal Ceroid Lipofuscinosis, a rare neurological disorder.
