Scientists Take Baby Steps Toward Extraterrestrial Babies | WIRED
In February, the Spanish pilot Daniel González climbed into a small aerobatic plane at the Sabadell Airport outside Barcelona and fired up its single prop engine. Once he was in the air, González began a steep climb for about six seconds before entering a nosedive . The plane's rapid descent created a microgravity environment in the cockpit and for a few seconds, González felt what it was like to be an astronaut. Then he pulled on the yoke to bring the plane out of its dive and did it all over again.
This sort of parabolic flight isn't remarkable for an experienced aerobatic pilot like González. But the cargo on his flight was a little unusual: In the passenger seat of the plane sat a small box, loaded with tubes of frozen human sperm .
This was the third and final flight of a yearlong study undertaken by a group of Spanish researchers to understand the effects of microgravity on human reproduction . This seminal study, which is currently under peer review, marks the first experimental results published on the effects of a zero-gravity environment on frozen sperm. The study was limited—the sperm was in microgravity for less than 9 seconds, for example—but it suggested that reduced gravity has negligible effects on the health of frozen sperm.
Did an extraterrestrial impact trigger the extinction of ice-age animals?
A controversial theory that suggests an extraterrestrial body crashing to Earth almost 13,000 years ago caused the extinction of many large animals and a probable population decline in early humans is gaining traction from research sites around the world.
The Younger Dryas Impact Hypothesis, controversial from the time it was presented in 2007, proposes that an asteroid or comet hit the Earth about 12,800 years ago causing a period of extreme cooling that contributed to extinctions of more than 35 species of megafauna including giant sloths, sabre-tooth cats, mastodons and mammoths. It also coincides with a serious decline in early human populations such as the Clovis culture and is believed to have caused massive wildfires that could have blocked sunlight, causing an "impact winter" near the end of the Pleistocene Epoch.
In a new study published this week in Scientific Reports , a publication of Nature, UofSC archaeologist Christopher Moore and 16 colleagues present further evidence of a cosmic impact based on research done at White Pond near Elgin, South Carolina. The study builds on similar findings of platinum spikes -- an element associated with cosmic objects like asteroids or comets -- in North America, Europe, western Asia and recently in Chile and South Africa.
Nasa to look for alien tech made by advanced extraterrestrial civilisations | Metro News
It has joined up with the Breakthrough Listen initiative to launch a search for 'technosignatures' – the traces of technology which indicate the existence of 'advanced extraterrestrial civilisations'.
These could include massive structures like Dyson Spheres, which are hypothetical 'megastructures' built around stars to harvest their power.
But technosignatures could be signals which seem to be produced by artificial transmitters or perhaps even the engines of alien spaceships.
The Search for Extraterrestrial Intelligence (SETI) drive will utilise the power of the TESS satellite, which is currently searching for planets.
It detects the presence of alien worlds orbiting distant suns by watching a telltale dip in the star's light, indicating a planet's 'transit' in front of it.
Not to change the topic here:
Asteroid wiped out giant sloths, woolly mammoths 12,800 years ago
A shocking new study claims the “smoking gun” behind the extinction of a number of animals and plants has been found: a massive asteroid that hit the Earth nearly 13,000 years ago.
The research, published in Scientific Reports , suggests that a brief ice age period occurred roughly 12,800 years ago and was caused by an asteroid impact, after looking at high levels of iridium and platinum in White Pond near Elgin, SC.
"We continue to find evidence and expand geographically,” University of South Carolina archaeologist Christopher Moore said in a statement. “There have been numerous papers that have come out in the past couple of years with similar data from other sites that almost universally support the notion that there was an extraterrestrial impact or comet airburst that caused the Younger Dryas climate event."
