‘Space Warps’ and other citizen science projects reap major dividends for astrophysics

Posted by in categories: physics, science, space

The astrophysics project Space Warps offers a compelling example of why citizen science has become such a popular tool and how valuable it can be. In a roundtable discussion with the Kavli Foundation, citizen science leaders and astrophysicists Chris Lintott, Anupreeta More and Aprajita Verma discuss the tremendous impact these enthusiastic volunteers are having.

New theory of secondary inflation expands options for avoiding an excess of dark matter

Posted by in categories: cosmology, physics

A new theory from physicists at the U.S. Department of Energy’s Brookhaven National Laboratory, Fermi National Accelerator Laboratory, and Stony Brook University, which will publish online on January 18 in Physical Review Letters, suggests a shorter secondary inflationary period that could account for the amount of dark matter estimated to exist throughout the cosmos.

“In general, a fundamental theory of nature can explain certain phenomena, but it may not always end up giving you the right amount of dark matter,” said Hooman Davoudiasl, group leader in the High-Energy Theory Group at Brookhaven National Laboratory and an author on the paper. “If you come up with too little dark matter, you can suggest another source, but having too much is a problem.”

Measuring the amount of dark matter in the universe is no easy task. It is dark after all, so it doesn’t interact in any significant way with ordinary matter. Nonetheless, gravitational effects of dark matter give scientists a good idea of how much of it is out there. The best estimates indicate that it makes up about a quarter of the mass-energy budget of the universe, while ordinary matter — which makes up the stars, our planet, and us — comprises just 5 percent. Dark matter is the dominant form of substance in the universe, which leads physicists to devise theories and experiments to explore its properties and understand how it originated.

Comets can’t explain weird ‘alien megastructure’ star after all

Well well well……

It looks like we just might have some neighbors after all!

Hopefully their idea of a good housewarming present DOESN’T include planetary extermination! wink

Frozen Tardigrade Brought Back to Life After 30 Years

Posted by in categories: biotech/medical, space

Tardigrades, or “water bears,” are renowned for their remarkable survival skills. But these microscopic creatures are far more indestructible than we thought. In a recent experiment, scientists in Japan successfully revived a tardigrade that had been frozen for more than three decades.

That’s a new record.

Tardigrades are tiny water-dwelling extremophiles that are capable of withstanding some of the most severe environmental conditions, including freezing, total dehydration, radiation, and even the vacuum of space. Much of this has to do with their extraordinary genome, of which nearly 18% is comprised of DNA from other organisms, including plants, fungi, bacteria, and viruses.

‘Spermbots’ are a bionic suit for your sperm

Posted by in categories: cyborgs, transhumanism

One of the main causes of infertility in men is low sperm motility. That is to say, the sperm are present and alive, but they have the swimming prowess of a toddler that’s afraid to lose its water wings.

In short, they just aren’t fast enough to reach the egg.

It’s hard to fault them, I can’t get to the front door fast enough for the FedEx guy not to leave my package in the bushes these days.
