Researchers have developed an implantable fuel cell that may drive highly efficient brain implants of the future, helping paralysed patients regain control of their arms and legs.

Developed and designed by Rahul Sarpeshkar, associate professor of electrical engineering and computer science at MIT, and Benjamin Rapoport, former graduate student in Sarpeshkar`s lab, who led the study, the fuel cells runs on the same sugar that powers human cells – glucose.

Twins born to women in the early birth group at 37 weeks were significantly less likely to be small for their gestational age, according to a new study.

Quitting smoking has benefits even if it happens later in life, claims a new study after finding a strong link between smoking cessation and reduced mortality among people aged 60 or older.

The study, a meta analysis of 17 studies that looked at the risk of all-cause mortality in smokers 60 or older, found smoking cessation was linked with a 28 per cent reduction in mortality risk and its benefits were evident in all age groups including those aged 80 years and older.

Researchers have found a way to calm fears with a drug that alters brain chemistry and help in understanding people at risk of anxiety disorders, including those suffering post-traumatic stress disorder (PTSD).

“What is most compelling is our ability to translate first from mice to human neurobiology and then all the way out to human behaviour,” said Ahmad Hariri, neurobiologist at the Duke Institute for Genome Sciences & Policy. “That kind of translation is going to define the future of psychiatry and neuroscience.”

A 52-year-old Mexican man who lost his arms in a 2011 electrical accident became the first patient in Latin America to receive a double-arm transplant.

Surgeons at Mexico City`s Salvador Zubiran National Institute of Medical Science and Nutrition performed the May 18 operation on Gabriel Granados, who was discharged Thursday after a satisfactory recovery, the Health Secretariat said.

In a statement, the hospital said the donor was a 34-year-old man who had been declared brain dead.

Chiropractic treatment for neck pain, a common technique which involves applying thrusts to the neck area of the spine, should be abandoned as it carries a low risk of stroke, scientists have claimed.

Writing in the British Medical Journal, Neil O’Connell and colleagues from the Centre for Research and Rehabilitation at Brunel University said cervical spine manipulation may cause damage to the key neck arteries and lead to a stroke.

The technique is “unnecessary and inadvisable”, they said.

A technique that helps people control activity in a specific part of their brain has been found very effective in treating depression, a new study has claimed.

The Cardiff University study, published in the PLoS One journal, used MRI scanners to show eight people how their brains reacted to positive imagery.

Tucking into a home-cooked meal can make you live longer, new research says.

Researchers from Monash University, the National Defence Medical Centre and the National Health Research Institute, Taiwan, found that people who cooked at home at least five times a week were 47 percent more likely to still be alive after 10 years.

A patients` body called People for Better Treatment has rallied behind Bollywood star Aamir Khan for focusing on the “rot” in the Indian healthcare delivery system during his popular television programme.
