Groundbreaking nerve surgery allows 13 paralysed patients to regain the use of their arms

Groundbreaking nerve surgery has allowed 13 patients paralysed in car crashes and sporting accidents to use their arms again.

Doctors in Australia have successfully reconnected the patients' limbs to their brains by grafting healthy nerves in the place of damaged ones.

Faced with a lifetime of tetraplegia leaving them unable to move their arms or legs, the patients can now feed themselves, write and even use their phones.

Although the procedure has been around for years it has not been perfected and is not routinely used. But the repeated success of the surgery in this study, however, is hailed as an 'exciting' breakthrough in what could revolutionise life after devastating spinal cord injuries.


Obesity is now a bigger cause of deadly bowel, kidney, liver and ovarian cancer than smoking

Obesity is now a bigger cause of many types of cancer than smoking, scientists have revealed.

Excess weight causes thousands of more cases of bowel, kidney, liver and ovarian cancer than cigarettes every year.

And people who are dangerously overweight now outweigh smokers by two to one, experts say, with almost a third of British adults classed as obese.

Smoking remains the leading preventable cause of cancer but the number of smokers is falling while obesity rates rise.


The common cold 'could cure bladder cancer'

The common cold could one day be used to cure bladder cancer, research suggests.

A study found a strain of the cold virus called coxsackievirus (CVA21) destroys cancerous cells in the organ's inner lining.

The majority of the study's 15 patients showed signs of 'cell death' within their tumours after just one week of treatment.

And one cancer sufferer even had no trace of the disease remaining afterwards, the study showed.


Scientists eliminate HIV in the entire genome of lab mice for the first time ever

Scientists eliminated HIV from the entire genome of lab mice for the first time ever using a slow-acting drug and gene-editing.

The feat, revealed in a publication today, suggests this two-pronged technique could be the basis for the first universal cure in humans, with human clinical trials slated to start next summer.

A team, spearheaded by an HIV expert in Nebraska and a gene-editing expert in Philadelphia has presented the unprecedented fruits of a five-year project: using a slow-acting drug called LASER ART that corners the virus, followed by CRISPR Cas9 gene-editing that blitzes it.

In a new paper, they reveal this approach successfully eliminated HIV from the entire genome of a third of their lab mice.
