Zoo experiments detect dozens of animals from airborne DNA

Animals are constantly shedding DNA into their environment, traces of which can then be detected in soil and water – and now, perhaps even air. Two new studies collected air samples from zoos and were able to identify a range of animals living in and a… Continue reading Zoo experiments detect dozens of animals from airborne DNA

Nasal spray gel directly delivers Parkinson’s drugs to the brain

A hydrogel nasal spray could be the most direct route for drugs to treat Parkinson's disease

Getting drugs into the brain is no easy feat, but the nose is emerging as one of the most direct routes. Now, researchers in the UK have developed a hydrogel that can be administered as a nasal spray, lining the tissue and delivering a common Parkinson’s drug straight to the brain.

Extreme exoplanet likely has lava oceans and rain made of rocks

With well over 4,000 exoplanets discovered to date, there are worlds out there so weird they’d put Dr. Who writers to shame. The latest to join the ranks is K2-141b, a scorching planet where it rains rocks, winds whip around at supersonic speeds and hu… Continue reading Extreme exoplanet likely has lava oceans and rain made of rocks

How bilingualism can hold back a flood of Alzheimer’s symptoms

A new study has found that while bilingualism can hold back the symptoms of Alzheimer's disease, it can also lead to a faster decline down the track

A long line of research projects have found a range of benefits of bilingualism when it comes to the brain, from shortening recovery times from stroke to staving off the cognitive decline associated with dementia and Alzheimer’s. Scientists looking into the latter have uncovered some interesting new insights, finding that while knowing a second language can delay the onset of the disease, it can also significantly accelerate the deterioration into severe Alzheimer’s thereafter.
