Who am I? How cells find their identity
ScienceDaily: Health & Medicine : April 26, 2018, 11:15 am
A research group has investigated more closely how a single embryonic cell develops into a heart, nerve or blood cell. For the first time, the researchers have been able to reconstruct the developmental trajectories of individual embryonic cells. Their results also suggest that cells can change their path during their maturation process.
Evidence for persistent forest reliance by indigenous peoples in historical Sri Lanka

Working closely with Wanniyalaeto (Vedda) elders in Sri Lanka during the repatriation of skeletal remains, a team of researchers have demonstrated that while some indigenous hunter-gatherers in Sri Lanka made use of agricultural resources and trade connections with farmers and colonial power structures, others continued to subsist primarily on tropical forest resources as late as the 19th century.
New imaging system makes back surgery safer, faster and less expensive
ScienceDaily: Health & Medicine : April 26, 2018, 5:55 am
Researchers develop a new way to make back surgery safer, faster and more cost effective. Scientists have developed and tested a 3-dimensional, real-time optical tracking system, like a 'Google Maps' for the body.
Prosthetic arms can provide controlled sensory feedback
ScienceDaily: Health & Medicine : April 26, 2018, 3:00 am
Losing an arm doesn't have to mean losing all sense of touch, thanks to prosthetic arms that stimulate nerves with mild electrical feedback. Researchers have developed a control algorithm that regulates the current so a prosthetics user feels steady sensation, even when the electrodes begin to peel off or when sweat builds up.
