Aging Is Linked to More Activity in Short Genes Than in Long Genes

Posted by in categories: bioengineering, biotech/medical, chemistry, genetics, life extension

Our DNA is made up of genes that vary drastically in size. In humans, genes can be as short as a few hundred molecules known as bases or as long as two million bases. These genes carry instructions for constructing proteins and other information crucial to keeping the body running. Now a new study suggests that longer genes become less active than shorter genes as we grow older. And understanding this phenomenon could reveal new ways of countering the aging process.

Luís Amaral, a professor of chemical and biological engineering at Northwestern University, says he and his colleagues did not initially set out to examine gene length. Some of Amaral’s collaborators at Northwestern had been trying to pinpoint alterations in gene expression—the process through which the information in a piece of DNA is used to form a functional product, such as a protein or piece of genetic material called RNA—as mice aged. But they were struggling to identify consistent changes. “It seemed like almost everything was random,” Amaral says.

Then, at the suggestion of Thomas Stoeger, a postdoctoral scholar In Amaral’s lab, the team decided to consider shifts in gene length. Prior studies had hinted that there might be such a large-scale change in gene activity with age—showing, for example, that the amount of RNA declines over time and that disruptions to transcription (the process through which RNA copies, or transcripts, are formed from DNA templates) can have a greater impact on longer genes than shorter ones.

Dawn of Solid-State Quantum Networks — The Holy Grail of Quantum Information Sciences

Posted by in category: quantum physics

Researchers demonstrated high-visibility quantum interference between two independent semiconductor quantum dots — an important step toward scalable quantum networks.

Last year’s Nobel Prize in Physics celebrated the fundamental interest of quantum entanglement, and also envisioned the potential applications in “the second quantum revolution” — a new age when we are able to manipulate the weirdness of quantum mechanics, including quantum superposition and entanglement. A large-scale and fully functional quantum network is the holy grail of quantum information sciences. It will open a new frontier of physics, with new possibilities for quantum computation, communication, and metrology.

One of the most significant challenges is to extend the distance of quantum communication to a practically useful scale. Unlike classical signals that can be noiselessly amplified, quantum states in superposition cannot be amplified because they cannot be perfectly cloned. Therefore, a high-performance quantum network requires not only ultra-low-loss quantum channels and quantum memory, but also high-performance quantum light sources. There has been exciting recent progress in satellite-based quantum communications and quantum repeaters, but a lack of suitable single-photon sources has hampered further advances.

Could humans use black holes to time travel?

Posted by in categories: cosmology, space travel, time travel

Black holes form natural time machines that allow travel to both the past and the future. But don’t expect to be heading back to visit the dinosaurs any time soon.

At present, we don’t have spacecraft that could get us anywhere near a black hole. But, even leaving that small detail aside, attempting to travel into the past using a black hole might be the last thing you ever do.

Google’s New AI Learned To See In The Dark! 🤖

Posted by in categories: information science, open access, robotics/AI

GOOGLE’S NEW SENSOR DENOISNG ALGORITHM brings yet another game changer for LOW LIGHT PHOTOGRAPHY. Within a handful of years, this will be added to other factors coming down the pipe, giving further impetus to a revolution in night vision. The video below speaks for itself. In effect, the system takes a series of images from different angles, exposures, and so on, then accurately reconstructs what is missing:

This infographic shows how nuclear fusion really works

Posted by in category: futurism

Nuclear fusion occurs when immense forces compress and heat hydrogen plasma. But it may be decades before it can be used on a commercial scale.

Google’s Sergey Brin talks AI safety efforts to prevent ‘sci-fi style sentience’

Posted by in categories: biotech/medical, Elon Musk, information science, robotics/AI

Google co-founder Sergey Brin has taken a rather similar stance as Tesla CEO Elon Musk on artificial intelligence, emphasizing AI dangers in a recent investor communication. According to the Russian-born billionaire, the present day is an era of possibilities, but it is also a time when responsibility has to be practiced, particularly when it comes to emerging technologies.

“We’re in an era of great inspiration and possibility, but with this opportunity comes the need for tremendous thoughtfulness and responsibility as technology is deeply and irrevocably interwoven into our societies,” he wrote.

Brin’s statements were outlined in Alphabet’s recent Founders’ Letter, where the 44-year-old billionaire described how Google is utilizing bleeding-edge technology for its ventures. While AI as a discipline is still an emerging field, Brin noted that there are already a lot of everyday applications for the technology. Among these are the algorithms utilized by Waymo’s self-driving cars, the smart cooling units of Google’s data centers, and of course, Google Translate and YouTube’s automatic captions.

We’ve just discovered a new part of the brain’s waste disposal system

Posted by in categories: biotech/medical, neuroscience

In 2012, Nedergaard also helped to discover a network of thin tubes that collect waste fluid from brain cells, known as the glymphatic system. These tubes may drain into the outgoing cerebrospinal fluid, says Nedergaard.

The waste products of brain cells include proteins called beta-amyloid and tau that are thought to be involved in Alzheimer’s disease when they build up in excessive amounts.

In both mice and people, the SLYM also contains immune cells, so it may allow them to detect signs of infection present in the cerebrospinal fluid, says Nedergaard. “It is loaded with immune cells.”
