Loose RNA Stimulates Skin Regeneration

Posted by in categories: biotech/medical, life extension

Researchers from Johns Hopkins University have published a new study that sheds light on skin rejuvenation, and it shares a link with what some cosmetic companies are doing using laser therapy.

A link between cosmetics and regeneration

During their study, the researchers found that the laser treatments used by cosmetic companies and retinoic acid, which is produced by the skin and sold commercially to treat wrinkles and sun damage, also target the same pathway. In addition, they also found that the activity of this pathway is increased in mice when they regenerate their hair follicles [1].

Tiny vibration-powered robots the size of the world’s smallest ant

Posted by in categories: 3D printing, biotech/medical, robotics/AI

Researchers have created a new type of tiny 3D-printed robot that moves by harnessing vibration from piezoelectric actuators, ultrasound sources or even tiny speakers. Swarms of these “micro-bristle-bots” might work together to sense environmental changes, move materials—or perhaps one day repair injuries inside the human body.

The respond to different frequencies depending on their configurations, allowing researchers to control individual bots by adjusting the vibration. Approximately two millimeters long—about the size of the world’s smallest ant—the bots can cover four times their own length in a second despite the physical limitations of their small size.

First programmable memristor computer aims to bring AI processing down from the cloud

Posted by in categories: mobile phones, robotics/AI

The first programmable memristor computer—not just a memristor array operated through an external computer—has been developed at the University of Michigan.

It could lead to the processing of artificial intelligence directly on small, energy-constrained devices such as smartphones and sensors. A smartphone AI processor would mean that voice commands would no longer have to be sent to the cloud for interpretation, speeding up response time.

“Everyone wants to put an AI processor on smartphones, but you don’t want your cell phone battery to drain very quickly,” said Wei Lu, U-M professor of electrical and and senior author of the study in Nature Electronics.

Electrical engineering team develops ‘beyond 5G’ wireless transceiver

Posted by in categories: computing, engineering, internet, nanotechnology

A new wireless transceiver invented by electrical engineers at the University of California, Irvine boosts radio frequencies into 100-gigahertz territory, quadruple the speed of the upcoming 5G, or fifth-generation, wireless communications standard.

Labeled an “end-to-end transmitter-receiver” by its creators in UCI’s Nanoscale Communication Integrated Circuits Labs, the 4.4-millimeter-square silicon chip is capable of processing digital signals significantly faster and more energy-efficiently because of its unique digital-analog architecture. The team’s innovation is outlined in a paper published recently in the IEEE Journal of Solid-State Circuits.

“We call our chip ‘beyond 5G’ because the combined speed and data rate that we can achieve is two orders of magnitude higher than the capability of the new wireless standard,” said senior author Payam Heydari, NCIC Labs director and UCI professor of electrical engineering & computer science. “In addition, operating in a higher frequency means that you and I and everyone else can be given a bigger chunk of the bandwidth offered by carriers.”

Ebola Outbreak in Congo Is Declared a Global Health Emergency

Posted by in categories: biotech/medical, health

The year-old Ebola epidemic in the Democratic Republic of Congo is now considered a global health emergency, the World Health Organization said on Wednesday, in a formal declaration that many public health experts called long overdue.

“This is still a regional emergency and by no way a global threat,” said Robert Steffen of the University of Zurich, chairman of the W.H.O. emergency committee that recommended the declaration.

But the panel was persuaded by several factors that have made combating the epidemic more urgent in recent weeks: The disease reached Goma, a city of nearly two million people; the outbreak has raged for a year; the virus has flared again in spots where it had once been contained; and the epidemic hot zone has geographically expanded in northeastern Congo near Rwanda and into Uganda.

Electronic chip mimics the brain to make memories in a flash

Posted by in categories: biotech/medical, cyborgs, genetics, robotics/AI, transhumanism

Researchers from RMIT University have drawn inspiration from optogenetics, an emerging tool in biotechnology, to develop a device that replicates the way the brain stores and loses information. Optogenetics allows scientists to delve into the body’s electrical system with incredible precision, using light to manipulate neurons so that they can be turned on or off.

The new is based on an ultra-thin material that changes electrical resistance in response to different wavelengths of light, enabling it to mimic the way neurons work to store and delete information in the brain. Research team leader Dr. Sumeet Walia said the technology has applications in (AI) technology that can harness the brain’s full sophisticated functionality.

“Our optogenetically-inspired chip imitates the fundamental biology of nature’s best computer—the human brain,” Walia said. “Being able to store, delete and process information is critical for computing, and the brain does this extremely efficiently. We’re able to simulate the brain’s neural approach simply by shining different colors onto our chip. This technology takes us further on the path towards fast, efficient and secure light-based computing. It also brings us an important step closer to the realization of a bionic brain—a brain-on-a-chip that can learn from its environment just like humans do.”

Scientists Find a New Kind of Cell That Helps Heal the Heart

Posted by in category: biotech/medical

The human body has plenty of nifty tricks to keep itself alive for as long as possible, and scientists still haven’t come close to figuring them all out. Case in point, a team of researchers this week describe a previously unknown type of cell near the heart that helps it heal from injury. The discovery could lead to new therapies or, at the very least, change how heart surgeons operate on our most precious organ, according to the researchers.

When an organ in our body gets injured, there are broadly two major sources of help it can marshal: the cells inside the organ, and the blood cells that can reach it through the networks of vessels that circulate all throughout the body. These blood cells can help clear debris and dying cells from the injury site, signal the rebuilding process to replace lost cells, and ward off foreign invaders like bacteria or viruses.

Viewpoint: Why CRISPR-edited crops should be allowed in organic agriculture

Posted by in categories: bioengineering, biotech/medical, food, genetics, health

A University of California, Berkeley professor stands at the front of the room, delivering her invited talk about the potential of genetic engineering. Her audience, full of organic farming advocates, listens uneasily. She notices a man get up from his seat and move toward the front of the room. Confused, the speaker pauses mid-sentence as she watches him bend over, reach for the power cord, and unplug the projector. The room darkens and silence falls. So much for listening to the ideas of others.

Many organic advocates claim that genetically engineered crops are harmful to human health, the environment, and the farmers who work with them. Biotechnology advocates fire back that genetically engineered crops are safe, reduce insecticide use, and allow farmers in developing countries to produce enough food to feed themselves and their families.

Now, sides are being chosen about whether the new gene editing technology, CRISPR, is really just “GMO 2.0” or a helpful new tool to speed up the plant breeding process. In July, the European Union’s Court of Justice ruled that crops made with CRISPR will be classified as genetically engineered. In the United States, meanwhile, the regulatory system is drawing distinctions between genetic engineering and specific uses of genome editing.
