A Ghostly Solution: Strange Property of the Quantum Realm Enables Efficient Energy Harvesting in Tiny Device

Posted by in categories: energy, quantum physics

Scientists at the University of Colorado Boulder have tapped into a poltergeist-like property of electrons to design devices that can capture excess heat from their environment — and turn it into usable electricity.

The researchers have described their new “optical rectennas” in a paper published today (May 18, 2021) in the journal Nature Communications. These devices, which are too small to see with the naked eye, are roughly 100 times more efficient than similar tools used for energy harvesting. And they achieve that feat through a mysterious process called “resonant tunneling” — in which electrons pass through solid matter without spending any energy.

“They go in like ghosts,” said lead author Amina Belkadi, who recently earned her PhD from the Department of Electrical, Computer and Energy Engineering (ECEE).

Lifespan.io Starting Rapamycin Antiaging Human Trials

Posted by in categories: biotech/medical, life extension

Rapamycin has been proven to extend the lifespan of mice, warms and yeast. Lifespan.io is starting a large clinical trial named Participatory Evaluation (of) Aging (with) Rapamycin (for) Longevity Study, or PEARL, to see if the antiaging effects of Rapamycin apply to humans. This will be the first study to see if Rapamycin works as well in humans as it does in mice.

The PEARL trial will follow up to 200 participants over 12 months testing four different Rapamycin dosing regimens. It will be double-blind, randomized, placebo-controlled and registered with clinicaltrials.gov. The principal investigator is Dr. James P Watson at UCLA, who was also a PI for the famous TRIIM trial.

Gigajot Unveils World’s First Commercially Available Quanta Image Sensors

Posted by in categories: futurism, quantum physics

Photon counting and reliable photon number resolving, until now, only partially available utilizing esoteric EMCCD technology in highly controlled laboratory environments, is now possible with a compact form-factor camera, operating at room temperature — with the additional benefits of higher resolution and speed. “The ability to do photon counting at room temperature is a game changer for our research efforts in Astrophysics and Quantum Information Science,” said Dr. Don Figer, Director of Center for Detectors and the Future Photon Initiative in the College of Science, Rochester Institute of Technology.

Governments are deploying ‘wartime-like’ efforts to win the global semiconductor race

Posted by in categories: computing, mobile phones

These clever semiconductors make our internet-connected world go round. In addition to iPhones and PlayStations, they underpin key national infrastructure and sophisticated weaponry.

But recently there haven’t been enough of them to meet demand.

The reasons for the ongoing global chip shortage, which is set to last into 2022 and possibly 2023, are complex and multifaceted. However, nations are planning to pump billions of dollars into semiconductors over the coming years as part of an effort to sure up supply chains and become more self-reliant, with money going toward new chip plants, as well as research and development.

Brain-Computer Interface Translates Brain Signals Associated with Handwriting into Text

Posted by in categories: computing, information science, neuroscience

Researchers with the BrainGate Collaboration have deciphered the brain activity associated with handwriting: working with a 65-year-old (at the time of the study) participant with paralysis who has sensors implanted in his brain, they used an algorithm to identify letters as he attempted to write them; then, the system displayed the text on a screen; by attempting handwriting, the participant typed 90 characters per minute — more than double the previous record for typing with a brain-computer interface.

So far, a major focus of brain-computer interface research has been on restoring gross motor skills, such as reaching and grasping or point-and-click typing with a computer cursor.

Tyvak satellite on SpaceX rideshare mission carries tiny space telescope

Posted by in category: satellites

WASHINGTON — The Tyvak-0130 rideshare payload that flew to orbit May 15 on a SpaceX Falcon 9 carries a miniature space telescope for possible commercial use.

The technology was developed by Tyvak Nano-Satellite Systems and the Lawrence Livermore National Laboratory under a four-year agreement to advance compact telescopes for commercial applications, Tyvak’s CEO Christian “Boris” Becker said in an interview with SpaceNews.

Becker, a retired U.S. Navy rear admiral, was recently named chief executive of Tyvak, a satellite manufacturer in Irvine, California, owned by Terran Orbital.
