Purdue University researchers have developed a method to use magnetic fields to independently control individual microrobots operating within groups.

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.
“Space is lousy with profits. Consider the asteroid Ryugu: It’s made of so many tons of nickel, iron, cobalt, and water, it’s worth an estimated $95 billion.”
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.

The carcass was remarkably well preserved, but something was clearly wrong. A rounded hole through the interior jugal. Deep incisions along the ribs. Dents in the left scapula. A broken mandible.
This 45,000 year-old mammoth’s life ended violently at the hands of hunters. That wouldn’t be surprising—it’s well known that Pleistocene humans were expert mammoth killers—but for the location. It was excavated from a permafrost embankment at Yenisei bay, a remote spot in central Siberia where a massive river empties into the Arctic Ocean.
That makes this brutalized mammoth the oldest evidence for human expansion into the high Arctic by a wide margin. Its discovery, published today in Science, might push back the timeline for when humans entered the northernmost reaches of the world—including the first entries into North America.
