China’s supersonic submarine, which could go from Shanghai to San Francisco in 100 minutes, creeps ever closer to reality

Posted by in categories: energy, military

O.,o circa 2014.


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.)

Biologist discovers world’s highest-elevation mammal

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.

‘Favilavir’: First Approved Drug to Possibly Treat Coronavirus

Posted by in categories: biotech/medical, government, health

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.

‘Robotic Blacksmithing’: A Technology That Could Revive US Manufacturing

Posted by in categories: robotics/AI, transportation

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.

New brain reading technology could help the development of brainwave-controlled devices

Posted by in categories: biotech/medical, neuroscience

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.

Secret of the ‘immortal’ hydra’s regenerating ability uncovered

Posted by in categories: evolution, life extension, neuroscience

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.

Seeing is believing: Visualizing differences in RNA biology between single cells

Posted by in categories: biotech/medical, genetics

The genetic information of an organism is stored within DNA. It contains the code for making other molecules that make all cells and organs of the body functional. Interestingly, only 1% of DNA makes up genes, of which proteins are produced via RNA intermediaries. There is much debate on the role of the remaining DNA, but different types of RNA are thought to be produced from it and direct the fate of the cell. Even though each cell of the body contains the same DNA, how they read and process DNA to make RNA can differ quite dramatically between single cells. This has especially been known for the transcriptome, which includes all RNA that are produced from genes, but not so much for other RNA.

“Genes have been the main focus of biological research for a long time,” says lead author of the study Haruka Ozaki. “We wanted to focus on what we call read coverage of single-cell RNA sequencing (scRNA-seq) data, which also includes RNA that are not products of genes. Although we can measure the amount of different RNA a single cell produces by scRNA-seq technologies, we wanted to come up with a new method that also visualizes specifically read coverage, because only then we can get a full picture of RNA biology and how it contributes to cell biology at the single-cell level.”


To achieve their goal, the researchers developed a new computational tool that they called Millefy uses existing scRNA-seq data to visualize read coverage of single cells as a heat map, illustrating differences between individual cells on a relative scale. The researchers first demonstrated the utility of Millefy in a well-established mouse embryonic stem cell model by showing heterogeneity of read coverage between developing cells. They then applied Millefy to cancer cells from patients with triple-negative breast cancer, a particularly aggressive type of breast cancer. Not only did Millefy show heterogeneity between cancer cells in general, but it revealed heterogeneity in a specific aspect of RNA biology that had previously been unknown.
