People with multiple sclerosis may find that smoked cannabis provides relief from muscle tightness — spasticity — and pain, although the benefits come with adverse cognitive effects, according to a new study published in CMAJ (Canadian Medical Association Journal).

A male robin will be more diligent in caring for its young if the eggs its mate lays are a brighter shade of blue.

A study by a team of university and government scientists led by a Kansas State University researcher, indicates that genes responsible for seed shattering -- the process by which grasses disseminate their seeds -- were under parallel selection during sorghum, rice and maize domestication.

Health professionals commonly say, "Don't look and it won't hurt" before administering an injection, but is there any scientific basis for the advice? A group of German investigators has found that, in fact, your past experience with needle pricks, along with information you receive before an injection, shape your pain experience. Their research is published in th

A curious twist in a family of plant proteins called chalcone-isomerase recently was discovered by Salk Institute for Biological Studies scientist Joseph Noel and colleagues at Iowa State University led by Eve Wurtele.

Research from North Carolina State University will allow the development of energy-efficient LED devices that use ultraviolet (UV) light to kill pathogens such as bacteria and viruses. The technology has a wide array of applications ranging from drinking-water treatment to sterilizing surgical tools.

There's nothing worse than a shonky pool table with an unseen groove or bump that sends your shot off course: a new study has found that the same goes at the nano-scale, where the "billiard balls" are tiny electrons moving across a "table" made of the semiconductor gallium arsenide.

Perelman School of Medicine at the University of Pennsylvania researchers have discovered a mechanism involving the neurotransmitter dopamine that switches fruit fly behavior from being active during the day (diurnal) to nocturnal. This change parallels a human disorder in which increased agitation occurs in the evening hours near sunset and may also be due to higher than normal dop

Dr Julian Hiscox and Dr John Barr of the University's Faculty of Biological Sciences are working with the Health Protection Agency Porton (HPA) to build a bank of molecular signatures that will help identify the severity of virus infection from characteristic changes seen in cells. Currently the team is barcoding different strains of influenza virus and human respiratory syncytial virus (HRSV) - a

The foundation of biological inheritance is DNA replication – a tightly coordinated process in which DNA is simultaneously copied at hundreds of thousands of different sites across the genome. If that copying mechanism doesn't work as it should, the result could be cells with missing or extra genetic material, a hallmark of the genomic instability seen in most birth defects and
