Common bone density scan can predict later-life dementia risk

Researchers can now assess a person’s risk of developing late-life dementia using data from a common type of bone density scan. The study revealed calcification within the abdominal aorta can double one’s risk of developing dementia over the age of 80.

New gene editing tool reduces errors by nicking DNA not cutting

As important as CRISPR-Cas9 gene-editing is, it has a relatively high error rate, which can introduce potentially harmful mutations. German researchers have now developed a more refined tool that reduces errors by nicking DNA instead of cutting it.

Graphene electronic-tattoo monitors blood pressure over time

Scientists have developed a new electronic “tattoo” that can monitor a patient’s blood pressure continuously. The e-tattoo is made of graphene and can be worn for long periods without getting in the way, allowing for better health data.

New cryoprotectant chemicals could preserve organs without ice damage

Getting an organ from donor to recipient is a race against time, with many going to waste. Now, researchers in Australia have identified new cryoprotectants that could preserve organs and tissues for much longer without damaging them.

Merino wool bandages deliver breathable, biodegradable healing

We've seen a number of odd merino wool products over the years, but that didn't prepare us for wool bandages. New Zealand's WoolAid says that its natural bandages are better for healing and better for the environment.

1 in 500 men may carry extra chromosome, raising risk of some diseases

A comprehensive genetic analysis has found that one in 500 men have an extra sex chromosome, with most unaware. That’s much higher than previously thought, and it seems to increase their risk of diseases like diabetes and cardiovascular problems.

Existing cancer drug suppresses inflammation behind multiple sclerosis

The dysfunction of microglia in the central nervous system is linked to range of diseases, prompting a wide-ranging search for drugs that can alter their activity. New research, however, suggests we might already one such drug at our disposal.

Cocaine receptor found in brain could lead to new addiction treatments

Scientists at Johns Hopkins have identified a previously unknown mechanism of cocaine’s activity in the brain, which could open new types of treatment for addiction to the drug. Intriguingly, it seems to work differently in male and female mice.
