Fish in a wind tunnel?   How else will you learn how they fly?

It turns out flying fish can remain airborne for over 40 seconds and cover distances of up to a quarter mile hitting a top speed up to 40 miles an hours, says Haecheon Choi, a mechanical engineer from Seoul National University, Korea.

Choi said a children's science book inspired him to look into the aerodynamics of flying fish, and a paper of his results appear in The Journal of Experimental Biology.  Choi and colleague Hyungmin Park posted similar results in a poster for the American Physical Society meeting in 2006.

22 scientists have published a study they say provides clear evidence about the effectiveness of Non-pharmacological Therapies in Alzheimer's disease and are calling on governments to make these useful treatments readily available.

 A cure for Alzheimer's is not in sight and available drugs have worthwhile but limited benefits the study says scientifically developed and rigorously tested Non-pharmacological Therapies can significantly improve the lives of people with dementia and their caregivers. 

They say he strongest evidence is for individualized intervention packages for family caregivers which can improve the well-being of caregivers and help delay admissions to care homes.

What happens to the laws of physics if a fundamental constant turns out to be not a constant after all?   The 'magic number' known as the fine-structure constant, called 'alpha' by physicists,  appears to vary throughout the universe, according to a team of astrophysicists.

That means the laws of physics would vary throughout the universe also.

The arXiv preprint describes how they determined that the fine-structure constant 'alpha' varies by measuring light from a quasar as it red-shifted due to universal expansion.

In case you do not easily panic, you may have missed the story that two asteroids were passing close to Earth yesterday.  Not to worry, it happens all of the time, but because their existence was only discovered Sunday by the Catalina Sky Survey, people were concerned.

The 50-foot 2010 RX30 came within 154,000 miles of Earth, just over halfway from here to the moon (0.6 lunar distances if you want to impress your friends), yesterday morning and then 2010 RF12, about 30 feet in size, came within 50,000 miles of Earth yesterday afternoon.
