Controlling air flow over wings during supersonic flight
EU-funded researchers evaluated control techniques of air flow over aeroplane wings during supersonic flight. The optimal wing design developed should lead to important reductions in noise, emissions and ...
Skydiver aims to break sound barrier in free fall
His blood could boil. His lungs could overinflate. The vessels in his brain could burst. His eyes could hemorrhage. And, yes, he could break his neck while jumping from a mind-boggling altitude of 23 miles (37 kilometers).
Temperatures measured at Gale Crater higher than expected
(Phys.org)—Preliminary weather reports from the Curiosity's Remote Environment Monitoring Station (REMS) are showing some surprisingly mild temperatures during the day. Average daytime air temperatures ...

Harvard researchers develop new kind of soft robotic gripper
GPS can now measure ice melt, change in Greenland over months rather than years
Researchers have found a way to use GPS to measure short-term changes in the rate of ice loss on Greenland and reveal a surprising link between the ice and the atmosphere above it.
Study: Weather might impact tone of Olympics coverage
(Phys.org) -- Whether it rains or shines might actually have an impact on how journalists cover the Olympics, according to researchers at Penn State.
New study shows correlation between summer Arctic sea ice cover and winter weather in Central Europe
Even if the current weather situation may seem to speak against it, the probability of cold winters with much snow in Central Europe rises when the Arctic is covered by less sea ice in summer. Scientists of the Research Unit ...
Microbial life on Mars: Could saltwater make it possible?
(PhysOrg.com) -- How common are droplets of saltwater on Mars? Could microbial life survive and reproduce in them? A new million-dollar NASA project led by the University of Michigan aims to answer those questions.

Cold winters mean more pollution
Differences in air pressure over the North Atlantic have meant that the last two winters in Gothenburg, Sweden, have been extremely cold. This has led to the air in Gothenburg being more polluted with nitrogen ...
Under pressure: Stormy weather sensor for hurricane forecasting
Its hard to believe that, in this day and age, we dont have a way to measure sea-level air pressure during hurricanes. NASA researchers, however, are working on a system that will improve forecasting ...

Putting muscle into birdsong: Wide range of pitch is due to vocal muscles more than air pressure
Female zebra finches don't sing but make one-note, low-pitch calls. Males sing over a wide range of frequencies. University of Utah scientists discovered how: The males' stronger vocal muscles, not the pressure ...
