A whole new way to treat paralysis. Scientists have figured out how to make nerve fibres repair themselves in mice, having identified a gene that inhibits fibre regrowth when nerve connections become damaged. This gene, called Cacna2d2, acts as ‘molecular brake’, but now that we know how to turn the brake off, it could help […]

The death toll from malaria has been reduced by more than half since 2000, thanks to a multi-pronged attack. But a lot more remains to be done. There’s no vaccine for malaria yet, but the world has been getting better at treating and preventing the deadly disease, according to a new study. The research, published in […]
A 28-year-old man left paralyzed after a car accident has been able to feel as though he was touching something with his fingers after a robotic arm was connected directly to his brain in a world-first breakthrough. Nathan Copeland, who was injured after crashing his car on a rainy night in Pennsylvania when he was just 18, spoke […]
Alzheimer’s disease is devastating both for those who suffer from it and for those who love them. It is also expensive. It’s estimated that the current worldwide cost of coping with Alzheimer’s is $818 billion. A cure for Alzheimer’s is not available and current treatments for the disease focus on mitigating symptoms rather than eliminating causes.
Scientists say early experiments suggest it may one day be possible to make babies without using eggs. They have succeeded in creating healthy baby mice by tricking sperm into believing they were fertilising normal eggs. The findings in Nature Communications, could, in the distant future, mean women can be removed from the baby-making process, say […]
Groundbreaking 3D printing and scanning techniques are improving access to fully customisable artificial limbs Before the vehicle that she was travelling in flipped over and trapped her right leg, Leakhena Laing was a happy teenager who enjoyed climbing trees and playing football with friends. After her limb was amputated, she could only sit and watch.
The world’s first three-parent baby has been born. Scientists revealed the birth of a baby boy, now five months old, usingDNA from three parents. Fertility experts hailed the breakthrough as “great news and a huge deal” for the future of reproduction. But they expressed concern that it was only achieved because US scientists crossed the […]
Egyptian researchers have developed a bandage embedded with nanoparticles for the treatment of wounds using the anti-epilepsy drug Phenytoin, known for its capacity to treat skin injuries. The bandage can heal wounds in a few days, after just one application to soft tissue. Wounds normally take several days to a few weeks to heal completely, […]
The R2D2 is magnitudes more stable than the steadiest surgeon’s hand. Doctors at Oxford University made medical history recently by successfully completing the first robot-assisted intraocular surgery. Robert MacLaren, Professor of Ophthalmology at the university, and his team managed to gently peel off a 1/1000th millimeter membrane from the inside of a patient’s eye. To […]
After generations of peering into a microscope to examine cells, scientists could simply stroll straight through one. Calling his project the “stuff of science fiction,” director of the 3D Visualisation Aesthetics Lab at the University of New South Wales (UNSW) John McGhee is letting people come face-to-face with a breast cancer cell.
