Public leaders & health officials:
The only thing that matters right now is the speed of your response.
A team led by UC Riverside geologists has discovered the first ancestor on the family tree that contains most familiar animals today, including humans.
The tiny, wormlike creature, named Ikaria wariootia, is the earliest bilaterian, or organism with a front and back, two symmetrical sides, and openings at either end connected by a gut. The paper is published today in Proceedings of the National Academy of Sciences.
The earliest multicellular organisms, such as sponges and algal mats, had variable shapes. Collectively known as the Ediacaran Biota, this group contains the oldest fossils of complex, multicellular organisms. However, most of these are not directly related to animals around today, including lily pad-shaped creatures known as Dickinsonia that lack basic features of most animals, such as a mouth or gut.

Researchers in China are reporting that they’ve taken a big step towards creating a supersonic submarine. This technology, which could just as easily be applied to weaponized torpedoes as military or civilian submarines, could theoretically get from Shanghai to San Francisco — about 6,000 miles — in just 100 minutes. If all this doesn’t sound crazy enough, get this: This new advance by the Chinese is based on supercavitation, which was originally developed by the Soviets in the ’60s, during the Cold War.
As you may already know, it’s a lot harder for an object to move quickly through water than air. This is mostly due to increased drag. Without getting into the complexities of fluid dynamics, water is simply much thicker and more viscous than air — and as a result it requires a lot more energy for an object to push through it. You can experience the increased drag of water yourself next time you’re in a swimming pool: Raise your hand above your head, and then let it fall towards the water. (Or alternatively, if there are people sunbathing nearby, do a belly flop.)
Anyway, much like a small-engined car is ultimately limited by its ability to cut through wind resistance (drag), a submarine or torpedo needs insane amounts of power to achieve high velocity through water. This is why, even in 2014, most submarines and torpedoes can’t go much faster than 40 knots (~46 mph). Higher speeds are possible, but it requires so much power that it’s not really feasible (torpedoes only have so much fuel).
They had climbed for eight hours—Had it really been just eight? Nine, maybe? More?—after the avalanche risk of a snow-packed ravine on the main path had forced them onto a more circuitous, arduous route.
Up here, the summer weather of February felt uncomfortably similar to a Nebraska winter.
“Jay, hay un ratón!” (“Jay, there’s a mouse!”)
An ancient fountain has been found under volcanic debris in Pompeii which was destroyed by the eruption of Mount Vesuvius in the year 79 A.D.
As the COVID-19 cases continue to rise globally, the National Medical Products Administration of China has approved the first-ever antiviral medicine called Favilavir. This medicine is said to possibly treat the now-declared pandemic illness.
Over the weekend, Taizhou’s city government announced that Favilavir, which was initially formulated by a Chinese-owned pharmaceutical firm, is the first medicine authorized to stop the widespread of this fatal illness. At present, this drug is being promoted with the label, Avigan.
According to the Ministry of Science and Technology of China, the Favilavir of Hisun Pharmaceutical is among the three drugs that have presented results for hindering COVID-19 (in initial trials) from spreading and further damaging the health of the people worldwide.
Now a new manufacturing method dubbed “robotic blacksmithing” has the potential to revolutionize the way high-quality structural parts are made, resulting in a new class of customized and optimized products. I am part of a loose coalition of engineers developing this process, a technique I believe can help revive U.S. manufacturing.
Today’s Technologies
Metal parts are used in all kinds of high-performance and safety-critical applications in transportation, mining, construction and power-generation equipment such as turbine engines. Most are made using one of a small number of classical manufacturing processes that haven’t changed much in decades.
A new method to accurately record brain activity at scale has been developed by researchers at the Crick, Stanford University and UCL. The technique could lead to new medical devices to help amputees, people with paralysis or people with neurological conditions such as motor neurone disease.
The research in mice, published in Science Advances, developed an accurate and scalable method to record brain activity across large areas, including on the surface and in deeper regions simultaneously.
Domestic cat genome sequenced

The DNA of a 4-year-old female Abyssinian cat named Cinnamon has been sequenced, according to a report by Joan U. Pontius, PhD, et al.
The hydra is named after the serpent monster from Greek myth, which regrows two heads each time one is cut off. But freshwater hydras have an even more impressive regenerating ability: an entire hydra can regrow from a small piece of tissue in only a few days.
Biologists are particularly excited by this ability, since many of the networks involved in the healing process developed early in the process of evolution, meaning that they are shared among many animals, including humans.
“In other organisms, like humans, once our brain is injured, we have difficulty recovering because the brain lacks the kind of regenerative abilities we see in hydra,” said researcher Abby Primack.
