Humans have the best of all possible visual worlds because our full stereo vision combines with primitive visual pathways to quickly spot danger, a study led by the University of Sydney has discovered.

The surprising finding published today in Current Biology shows that in humans and other primates, information from the eyes is not only sent to the visual cortex for the complex processing that allows stereoscopic vision, but also could feed directly into deep brain circuits for attention and emotion.

New research from the Department of Developmental Neurobiology at the Institute of Psychiatry, Psychology & Neuroscience, King's College London, sheds light into the role of layers in the brain. The study, published today in Neuron, shows that the formation of layers speeds the development of neuronal circuits although, surprisingly, it is not crucial for the establishment of functional and cell-type specific connections.

The concentration of the euphoriant THC in cannabis has tripled in the space of twenty years. The reason may be a systematic processing of the cannabis plants, some of which are being grown in skunk farms in Denmark.

Cannabis being sold on the street in Denmark is stronger than previously measured. This is shown by analyses carried out by the three forensic chemistry departments in Denmark and processed by the Department of Forensic Medicine at Aarhus University. The levels are published in the Danish Health and Medicines Authority's annual narcotics report on 18 November.

The upside to modern cancer treatment, like chemotherapy, is obvious; people are living more, and living longer. The downside is that some food tastes terrible. 

Chemotherapy, by design, kills all fast-growing cells in the body. As cancer cells die, so do all the healthy fast-growing cells, including the cells responsible for hair growth and taste buds. So your hair falls out and everything tastes metallic.

"Here they are, critically ill, needing good nutrition more than ever, and they can't enjoy food? It's beyond unfair," said Dan Han, a psychologist at the University of Kentucky. 

ANN ARBOR, Mich. -- If you think your life is stressful, try being a new doctor.

The first year after medical school, called internship, means round-the-clock hours, low rank, constant demands from patients and superiors, learning complex new skills and constant fear of making a mistake that could harm a patient.

The result: A year of stress, sleeplessness and self-doubt that drives up thoughts of suicide to nearly four times the normal rate.

But help may be as close as the smartphone in the pocket of an intern's white coat. A new study shows that a free web-based tool to support their mental health may cut the rate of suicidal thoughts in half.

Montreal, Nov. 19, 2015 - A new injectable 'biogel' is effective in delivering anti-cancer agents directly into cancerous tumours and killing them. This technology, developed by researchers at the University of Montreal Hospital Research Centre (CRCHUM), has already been successfully tested in the laboratory. If it works in patients, the therapy could one day revolutionize treatment for many forms of cancer.
