Elon Musk Shares Transphobic Meme Following Report of Grimes Dating Chelsea Manning

Sooner or later Musks childish, morally and politically inept use of social media will thwart his greater (and great) ambition. Whatever your personal beliefs, there is exactly ZERO doubt that every generation since and including millennials has become exponentially less willing to tolerate this kind of stuff. Musk is going to NEED to both the fresh and enthusiastic intelligence and majority scale support, and not JUST in SpaceX research labs and on site engineering teams either.
He’s going to need IMMENSE, PROLONGED, and RELIABLE political support even as the reins of power are being passed from one generation to the next. If he keeps using Twitter like he has nothing to lose and no one’s support He’s going to find that he really does no longer have anything to lose nor anyones support.
At that point, he’ll have difficulty getting from city to city, much less get to Mars to build CITIES or become a secure, far more survivable interplanetary civilization!

New DNA Modification System Discovered in Animals — “It’s Almost Unbelievable”
Posted by Kelvin Dafiaghor in categories: biotech/medical, genetics
Marine Biological Laboratory finds gene captured from bacteria more than 60 million years ago.
Your DNA holds the blueprint to build your body, but it’s a living document: Adjustments to the design can be made by epigenetic marks. Cataloguing these marks and how they work is important for understanding biology and genetics—and coming up with therapies to address diseases and disorders.
In humans and our fellow eukaryotes, two principal epigenetic marks are known. But a team from the University of Chicago-affiliated Marine Biological Laboratory has discovered a third, novel epigenetic mark—one formerly known only in bacteria—in small freshwater animals called bdelloid rotifers.

Exclusive: China captures powerful US NSA cyberspy tool
Posted by Saúl Morales Rodriguéz in categories: biotech/medical, cybercrime/malcode, internet
China captured a spy tool deployed by the US National Security Agency, which is capable of lurking in a victim’s computer to access sensitive information and was found to have controlled global internet equipment and stole large amounts of users’ information, according to a report the Global Times obtained from the National Computer Virus Emergency Response Center exclusively on Monday.
According to the report, the Trojan horse, “NOPEN,” is a remote control tool for Unix/Linux computer systems. It is mainly used for stealing files, accessing systems, redirecting network communication, and viewing a target device’s information.
Through technical analysis, the center believes that the “NOPEN” Trojan horse is characterized by complex technology, comprehensive functions and strong concealment, which can fit a variety of processor architectures and operating systems. It can also collaborate with other cyber weapons and is a typical tool used for cyber espionage.

New window system allows for long-term studies of brain activity
Posted by Dan Kummer in categories: biotech/medical, engineering, neuroscience
Bilal Haider is studying how multiple areas of the brain work together for visual perception. This could help researchers understand if neural activity “traffic jams” underlie all kinds of visual impairments: from running a red light when visual attention is elsewhere, to shedding light on the autism-affected brain.
To do this kind of work, researchers need a reliable “map” of all the visual brain areas with specific coordinates for each unique brain. Drawing the map requires monitoring and recording data from an active, working brain, which usually means creating a window in the skull to watch blood flow activity.
Haider’s team has developed a better approach—a new kind of window that’s more stable and allows for longer-term studies. The assistant professor in the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University explains how in a paper published in February in Scientific Reports.

Fully vaccinated will need fourth dose later this year, and new variant dubbed ‘deltacron’ detected in Europe
Posted by Quinn Sena in category: biotech/medical
Fully vaccinated people will need a fourth shot later in 2022, according to the head of Pfizer Inc., who said that COVID-19 is not going to just go away in the coming years.
Albert Bourla told CBS News anchor Margaret Brennan on “Face the Nation” that people are going to have to learn to live with the virus.
He said a fourth dose — that is, a second booster — is necessary “right now.”

How “bodies on a chip” can transform animal welfare
Posted by Quinn Sena in categories: biotech/medical, chemistry, computing
Circa 2019
When Ken-Ichiro Kamei, a microengineer at Kyoto University, goes out drinking with his friends, he usually brings along one of his “bodies on a chip.” When the topic of work inevitably comes up, he’ll whip out the chip – which looks like a lab slide, but with an added crystal-clear silicone rubber layer containing faintly visible troughs and channels – and declare, “I’m making these devices to recreate humans and animals.”
Wows inevitably ensue. “It’s like I’m a magician and my friends have asked me to do some tricks,” Kamei chuckles.

Seoul hospital completes robotic liver transplant surgery
Posted by Quinn Sena in categories: biotech/medical, robotics/AI
Circa 2021
Seoul National University Hospital completed a liver transplant procedure using a robot and a laparoscope that left no huge abdominal scars for both the donor and recipient.
Suh Kyung-suk, a professor on the liver transplant team, noted that the new surgical procedure also reduces complications associated with the lungs and scars and shortens the recovery time.

New algorithm could help enable next-generation deep brain stimulation devices
Posted by Dan Breeden in categories: bioengineering, biotech/medical, information science, neuroscience
Now, a new algorithm developed by Brown University bioengineers could be an important step toward such adaptive DBS. The algorithm removes a key hurdle that makes it difficult for DBS systems to sense brain signals while simultaneously delivering stimulation.
“We know that there are electrical signals in the brain associated with disease states, and we’d like to be able to record those signals and use them to adjust neuromodulation therapy automatically,” said David Borton, an assistant professor of biomedical engineering at Brown and corresponding author of a study describing the algorithm. “The problem is that stimulation creates electrical artifacts that corrupt the signals we’re trying to record. So we’ve developed a means of identifying and removing those artifacts, so all that’s left is the signal of interest from the brain.”
