How Dragonflies Right Up When Falling Upside Down

Dragonfly recovers from an upside down fall in ~200ms using a complex wing motion. Credit: Z. Jane Wang, Cornell University A trio of researchers, two from Cornell University, the other from the Howard Hughes Medical Institute, have discovered the means by which dragonflies are able to right themselves so quickly from an upside-down orientation.

Boeing’s Starliner spacecraft descends under parachute on December 22, 2019, at the end of the Orbital Flight Test-1 mission. Credit: NASA/Aubrey Gemignani Members of NASA’s Independent Safety Advisory Board warned the space agency on Thursday not to rush into a crewed test flight of Boeing’s troubled Starliner spacecraft, and expressed concerns over final certification of … Read more

For the first time, scientists have grown plants in lunar land. It didn’t go well

For the first time, scientists have grown plants in lunar land.  It didn't go well

When the Artemis program returns humans to the Moon in (hopefully) a few years, there will be considerable logistics to sort out to keep such fragile beings alive in such a hostile environment. The question of food is not the least. Space agencies involved with the International Space Station are now very experienced in providing … Read more

Computer powered by a colony of blue-green algae for 6 months

There is “green energy” and then there is really GREEN energy, or rather blue-green energy. A colorful colony of photosynthetic cyanobacteria, known as blue-green algae, successfully powered a computer microprocessor for more than six months, according to a published study Thursday in the journal Energy & Environmental Science. The small bio-based battery alternative could serve … Read more

A solar flare is expected to 'side-swipe' Earth TODAY causing a fluctuating geomagnetic storm on the power grid

SPACE experts are monitoring a new solar flare that could “graze” Earth today. The eruption was originally expected to hit Earth on Friday the 13th, but it could cause a solar storm much earlier. 1 A plasma explosion from the Sun could cause a solar storm todayCredit: Getty SpaceWeather.com experts explained, “Sunspot AR3007 has a … Read more
