Parkinson's disease and Amyotrophic Lateral Sclerosis are the newest frontiers for open science drug discovery, a global movement led by academic scientists that puts knowledge sharing and medication affordability ahead of patents and profits.

Drug to rejuvenate muscle cells

Researchers have developed a promising drug that has proven to significantly increase muscle size, strength and metabolic state in aged mice, according to a new study.

Genetic vulnerability to menthol cigarette use

A genetic variant found only in people of African descent significantly increases a smoker's preference for cigarettes containing menthol, a flavor additive. The variant of the MRGPRX4 gene is five to eight times more frequent among smokers who use menthol ci

Patients' own cells could be the key to treating Crohn's disease

A new technique using patients' own modified cells to treat Crohn's disease has been proven to be effective in experiments using human cells, with a clinical trial of the treatment expected to start in the next six months.

Laminitis research to help save horses and ponies

Laminitis -- a complex, common and often devastating disease -- is the second biggest killer of domestic horses. Now a body of important research on it has been compiled.

A nearby river of stars

Astronomers have found a river of stars, a stellar stream in astronomical parlance, covering most of the southern sky. The stream is relatively nearby and contains at least 4000 stars that have been moving together in space since they formed, about 1 billion

Tide gauges capture tremor episodes in cascadian subduction zone

Hourly water level records collected from tide gauges can be used to measure land uplift caused by episodic tremor and slip of slow earthquakes in the Cascadia Subduction Zone, according to a new report.

Tidal tails: The beginning of the end of an open star cluster

In the course of their life, open star clusters continuously lose stars to their surroundings. The resulting swath of tidal tails provides a glimpse into the evolution and dissolution of a star cluster. Thus far only tidal tails of massive globular clusters a

'Seeing' tails help sea snakes avoid predators

New research has revealed the fascinating adaptation of some Australian sea snakes that helps protect their vulnerable paddle-shaped tails from predators.

A cutting-edge technique called cellular barcoding has been used to tag, track and pinpoint cells responsible for the spread of breast cancer from the main tumour into the blood and other organs.

Exercise might improve health by increasing gut bacterial diversity

Research has suggested that the efficiency with which we transport oxygen to our tissues (cardiorespiratory fitness) is a far greater predictor of gut microbiota diversity than either body fat percentage or general physical activity.

New molecular blueprint advances our understanding of photosynthesis
