Surgeons have performed a gallbladder removal without having to make a single external incision, reducing pain, speeding recovery, and minimising visible scarring.

Researchers characterised genetic variation and detected more than one MHC class II locus in a tailed amphibian.

Gene-expression data from liver tissue or whole blood can be used to classify histopathologic differences in the effects of hepatotoxins.

The Alpine newt (Mesotriton alpestris) is the only known tailed amphibian with more than one Major Histocompatibility Complex II locus.

Researchers from Northwestern University and Texas A & M University have discovered a new way to limit gene transfer and expression to specific tissues in animals.

The drug tPA is the most effective treatment currently available for stroke patients, but its safety is limited to use within the first three hours following the onset of symptoms.

UCLA researchers discovered that an FDA-approved drug reverses the brain dysfunction inflicted by a genetic disease called tuberous sclerosis complex.

Researchers have pinpointed a new, previously unrecognised group of stem cells that give rise to cardiomyocytes, or heart muscle cells.

Dogs vary in size, shape, colour, coat length and behaviour more than any other animal and until now, this variance has largely been unexplained.

UCLA researchers report that practising tai chi chih, the Westernised version of a 2,000-year-old Chinese martial art, promotes sleep quality in older adults.

Turmeric, an Asian spice found in many curries, has a long history of use in reducing inflammation, healing wounds and relieving pain, but can it prevent diabetes?

Scientists at UCLA suggest that such long-term or "complicated" grief activates neurons in the reward centres of the brain, possibly giving these memories addiction-like properties.

A new discovery by a scientist from The University of Western Ontario provides conclusive evidence supporting decades-old evolutionary doctrines.

A new paper describes, for the first time, how the flagellum's rotations are stopped so that bacteria stop moving.

A small molecule that locks an essential enzyme in an inactive form could one day form the basis of a new class of unbeatable, species-specific antibiotics.

These stem cells, located in the surface of the heart, or epicardium, advance the hope of being able to regenerate injured heart tissue.

Even today, the brain remains a mystery. Dr. Seth Grant, a researcher at the Wellcome Trust Sanger Institute, has been studying the links between human cognition and the brain. Scientist Live spoke with him about his work.
