People taking certain drugs to lower blood sugar for type 2 diabetes had less amyloid in the brain, a biomarker of Alzheimer's disease, when compared to both people with type 2 diabetes not taking the drugs and people without diabetes. The new study also found people taking these drugs, called dipeptidyl peptidase-4 inhibitors, showed slower cognitive decline than people in the other two groups.

People with stroke who walk 30 minutes per day may have 54% lower risk of early death
- ScienceDaily
- 21/8/11 23:51
A new study shows that people who walk or garden at least three to four hours per week, or bike at least two to three hours per week, or the equivalent after having a stroke may have a 54% lower risk of early death from any cause. The study found the most benefit for younger stroke survivors. When people under the age of 75 exercised at least that amount, their risk of early death was reduced by...
Atlantic Canada's offshore wind energy sector gets boost from new Ocean Supercluster project
A new $3.4-million project aims to help boost the Atlantic Canadian offshore wind energy sector's ability in install infrastructure in glacial seabeds.
Oxford/AstraZeneca vaccine: rare blood clot syndrome has high mortality rate
Researchers found that clots occurring after first dose of Oxford jab affected otherwise young and healthy peopleCoronavirus – latest updatesSee all our coronavirus coverageAlthough extremely rare, a blood clot syndrome after the first dose of the Oxford/AstraZeneca vaccine carries a high risk of death and can occur in otherwise young and healthy people, UK researchers have found.In those aged...
Birds that disperse more types of seed have better evolutionary chances
More than 70% of plant species that produce flowers depend on birds to disperse their seeds. Birds feed on fruit from a wide array of different plants, and bird-plant interactions configure a welter of complex networks.

Study shows differences in rapidly processing sensory feedback among people with autism spectrum disorder
- ScienceDaily
- 21/8/11 22:29
In an effort to better characterize -- and quantify -- sensorimotor abilities and their impact on the development of people with ASD, scientists have published research that compared the fine motor control and eye movements of more than 200 people from age 5 to 29. The study showed key differences in the ways that individuals with ASD processed or reacted to stimuli compared to those who were more...

A study reports on how bats and pepper plants in Central America have co-evolved to help each other survive.
Only slight chance of asteroid Bennu hitting Earth: NASA
An asteroid known as Bennu will pass within half the distance of the Earth to the Moon in the year 2135 but the probability of an impact with our planet in the coming centuries is very slight, scientists said Wednesday.

Identifying and researching different heat stress response patterns in corals will help to protect the world's reefs better from the effects of climate change. A new study describes the necessary test procedures and initial results.
Protecting Earth from space storms
- ScienceDaily
- 21/8/11 22:28
A major space weather event could have a catastrophic impact on Earth, disabling communications and electrical systems. Researchers are using the Frontera supercomputer to develop new geomagnetic forecasting methods and improve the Geospace Model used by NOAA for operational purposes. They hope to increase the lead time for space weather events from 30 minutes to 1-3 days, localize space weather...
Treating the ‘root’ cause of baldness with a dissolvable microneedle patch
- ScienceDaily
- 21/8/11 22:28
Although some people say that baldness is the 'new sexy,' for those losing their hair, it can be distressing. An array of over-the-counter remedies are available, but most of them don't focus on the primary causes: oxidative stress and insufficient circulation. Now, researchers have designed a preliminary microneedle patch containing cerium nanoparticles to combat both problems, regrowing hair in...
