Aerodynamics of perching birds could inform aircraft design

If you have ever watched a bird land on a tree branch, you may have noticed that it rapidly pitches its wings upward at a high angle to execute a smooth landing. However, for some birds, they land by folding their wings as ...

Chemically scrubbing CO2 from the air too expensive

(PhysOrg.com) -- While it is possible to chemically scrub carbon dioxide from Earth's atmosphere in order to lessen the severity of global warming, the process is prohibitively expensive for now. Best to focus on controls ...

How NASA prepares spacecraft for the harsh radiation of space

In a small, square room walled by four feet of concrete, the air smells as if a lightning storm just passed through—crisp and acrid, like cleaning supplies. Outside, that's the smell of lightning ripping apart oxygen in ...

Making industrial plasma safer

(Phys.org) —EPFL scientists have uncovered the physics behind the formation of plasmoids – funnel-like, high-energy plasmas that can severely damage industrial plasma reactors, causing millions in repairs and lost productivity ...

New camera makes seeing the 'invisible' possible

(PhysOrg.com) -- The science similar to the type used in airport body scanners could soon be used to detect everything from defects in aerospace vehicles or concrete bridges to skin cancer, thanks to researchers at Missouri ...
