Glycoproteins: Glycoprotein ##glycoprotein

Posted by in category: particle physics


Glycoproteins are a diverse group of proteins that have carbohydrate chains covalently attached to their polypeptide chains. These carbohydrate chains, or glycans, can vary greatly in size, complexity, and composition, leading to a wide range of glycoprotein functions and properties.

The attachment of glycans to proteins typically occurs in two main types of linkages: N-linked glycosylation, where the carbohydrate is attached to the nitrogen atom of asparagine side chains, and O-linked glycosylation, where it attaches to the oxygen atom of serine or threonine side chains. These modifications can significantly impact a glycoprotein’s structure, stability, and function.

SpaceX to test intense booster recovery limits during Galileo L13 launch from Cape Canaveral

Posted by in category: satellites

The current Galileo system consists of 28 satellites in all, and now, two more are expected to join the constellation. All of these satellites are in medium-Earth orbit besides two, which were incorrectly placed, the ESA says.

The first-stage booster supporting this mission is on its 22nd flight, SpaceX says, and Tuesday’s potential launch is expected to be a test of its recovery capabilities.

During a Galileo mission earlier this year, SpaceX was not able to recover the booster that supported the mission because it needed to go deep into space to deliver the payload. However, SpaceX says that the expended booster gave officials valuable data that helped them make design and operational changes.

Nvidia CEO: “We can’t do computer graphics anymore without artificial intelligence”

Posted by in categories: climatology, robotics/AI

In context: Upscaling tech like Nvidia’s DLSS can enhance lower-resolution images and improve image quality while achieving higher frame rates. However, some gamers are concerned that this technology might become a requirement for good performance – a valid fear, even though only a few games currently list system requirements that include upscaling. As the industry continues to evolve, how developers address these concerns remains to be seen.

AI, in its current primitive form, is already benefiting a wide array of industries, from healthcare to energy to climate prediction, to name just a few. But when asked at the Goldman Sachs Communacopia + Technology Conference in San Francisco last week which AI use case excited him the most, Nvidia CEO Jensen Huang responded that it was computer graphics.

“We can’t do computer graphics anymore without artificial intelligence,” he said. “We compute one pixel, we infer the other 32. I mean, it’s incredible… And so we hallucinate, if you will, the other 32, and it looks temporally stable, it looks photorealistic, and the image quality is incredible, the performance is incredible.”

Immunotherapy After Surgery Helps People With High-Risk Bladder Cancer Live Cancer-Free Longer

Posted by in categories: biotech/medical, food

Results from a large clinical trial show that treatment with an immunotherapy drug may nearly double the length of time people with high-risk, muscle-invasive bladder cancer are cancer-free following surgical removal of the bladder. Researchers found that postsurgical treatment with pembrolizumab (Keytruda), which is approved by the Food and Drug…

First of Its Kind DNA Computer Can Both Store Data And Solve Problems

Posted by in categories: biotech/medical, computing

For billions of years, life has used long molecules of deoxyribonucleic acid, or DNA, to store information and solve problems.

Today engineers are putting their own spin on DNA computing, to both record data and serve as biological computers, yet until now they’ve struggled to design a synthetic system that can store and perform tasks at the same time.

New research has now demonstrated it’s possible to package and present DNA so it can manage both, providing a full suite of computing functions out of strings of nucleic acids. Specifically, we’re talking about storing, reading, erasing, moving, and rewriting data, and handling these functions in programmable and repeatable ways, similar to how a conventional computer would operate.

Watch mesmerizing video of weird waves that ‘shape life itself’ inside a fly embryo

Posted by in category: biotech/medical

Mesmerizing microscopic footage showing “waves” inside a developing fly embryo has won the 14th annual Nikon Small World in Motion competition.

These “mitotic waves” occur during cell division as tissue forms and moves in the embryo of a fruit fly (Drosophila melanogaster). Understanding this biological process in flies could help reveal the forces that build embryos across the animal kingdom. Many of these fundamental processes can go awry in humans, leading to neurological disorders, congenital defects and cancer.

Dr. Hologram will see you now: Virtual specialists visit cancer patients

Posted by in categories: biotech/medical, holograms, mobile phones

Back in August 2021, LA-based Portl launched a 7-ft-tall hologram projection box for life-like remote communications. Now renamed Proto, the company has revealed that its Epic technology is allowing cancer patients to consult life-size virtual specialists.

Proto was founded in 2018 by David Nussbaum, who took his experience working on huge holograms for arena gigs, movie premieres and fashion shows to produce a hologram in a box called the Epic. The idea is to plonk the machine in a venue, university, boardroom, medical facility and so on, and allow folks to chat with a life-like 3D hologram of a person who might be thousands of miles away.
