Drugmakers struggle in search for cancer cocktails

After decades of frustratingly slow progress in discovering new drugs to battle cancer, the breakthroughs have started to come thick and fast. Futuristic cell therapies from Novartis and Gilead Sciences can reengineer the body to attack tumours, while a drug from Loxo Oncology produces spectacular results by zoning in on cancer genetics.

Scientists discover why humans have big brains

Three international research teams have solved a genetic mystery of evolution: how human brains got to be so big. Two groups of scientists have discovered a family of genes called Notch2NL, found only in humans, that played a critical role in the evolutionary expansion that made human intelligence and behaviour possible. Their findings appear in the journal Cell.
 A third team discovered how the brain maintained a healthy balance between different types of neuron as it more than doubled in size.

FDA permits marketing of artificial intelligence algorithm for aiding providers in detecting wrist fractures

"Artificial intelligence algorithms have tremendous potential to help health care providers diagnose and treat medical conditions," said Robert Ochs, Ph.D., acting deputy director for radiological health, Office of In Vitro Diagnostics and Radiological Health in the FDA's Center for Devices and Radiological Health. "This software can help providers detect wrist fractures more quickly and aid in the diagnosis of fractures."

Emergency Medicine Physician Back to Work After Accident That Left Him Paralyzed

Daniel Grossman, M.D., was in command and control mode, assessing a 36-year-old who'd fallen off his mountain bike on the Cuyuna Trail in northern Minnesota. No one had seen the fall, which cracked the man's helmet and left him unable to feel or move his legs.

Having worked for a decade as an emergency medicine physician, Dr. Grossman understood the gravity of the situation. But it was also completely new to him. Because this time, Dr. Grossman wasn't only the physician. He was also the patient.
