Harnessing noise in optical computing for AI

Artificial intelligence and machine learning are currently affecting our lives in many small but impactful ways. For example, AI and machine learning applications recommend entertainment we might enjoy through streaming services such as Netflix and Spotify.

In the near future, it’s predicted that these technologies will have an even larger impact on society through activities such as driving fully autonomous vehicles, enabling complex scientific research and facilitating medical discoveries.

But the computers used for AI and machine learning demand a lot of energy. Currently, the need for computing power related to these technologies is doubling roughly every three to four months. And cloud computing data centers used by AI and machine learning applications worldwide are already devouring more electrical power per year than some small countries. It’s easy to see that this level of energy consumption is unsustainable.

Anti-aging startup launches with $3bn in funding

“Altos Labs is just the latest in a series of anti-aging research institutes to emerge recently. With so much money being poured into the science of living longer, there is reason to be optimistic for those hoping to reach longevity escape velocity.”

Scientists Are Sequencing the Genome of Every Complex Species on Earth

The Earth Biogenome Project, a global consortium that aims to sequence the genomes of all complex life on Earth (some 1.8 million described species) in 10 years, is ramping up.

The project’s origins, aims, and progress are detailed in two multi-authored papers published this week. Once complete, it will forever change the way biological research is done.

Specifically, researchers will no longer be limited to a few “model species” and will be able to mine the DNA sequence database of any organism that shows interesting characteristics. This new information will help us understand how complex life evolved, how it functions, and how biodiversity can be protected.

The Cyborg Revolution: Are They Here Yet?

They are.

The cyborgs are upon us. Turns out, they’re more ‘enhanced reality’ and less ‘science fiction.’

In 1998, Professor of Cybernetics Kevin Warwick had a chip implanted in his body that would open electronic doors and turn on lights as he passed. In 2002, he had a 100 electrode array wired into the nervous system of his arm to allow him to remotely control an artificial hand. Today, he’s working on using animal brain cells as a control system for robots.

Performance artist Stelios Arcadiou (whose has changed his name to Stelarc) has spent 10 years growing an artificially-created ear that is surgically attached to his left arm. In 2009, Jerry Jalava, a Finnish computer engineer who lost part of a finger in a motorcycle accident, turned his prosthetic finger into a USB drive. Colorblind artist Neil Harbisson has an antenna that helps him to ‘hear’ colors. Avant-garde artist Moon Ribas had seismic sensors implanted in her feet that detect the vibrations caused by earthquakes, and records the data online. She then transforms that data into dance.

Full Story:

Cyborgs are already here. Ranging from a chip, to antenna and seismic sensors, humans have implanted them and iden.

Elon Musk’s Neuralink Took One Step Closer to Implanting Chips Into Human Brains

Elon Musk’s Neuralink, the company that purports to implant computer chips in human brains, just took a critical step toward actually following through.

The brain implant firm is officially hiring a clinical trial director, which means Musk’s futuristic firm is finally ready, at least on its own terms, to give next-gen brain-computer interfaces (BCIs) a try.

Of course, it’s hard to imagine being the one for whom the buck stops should anything go monstrously wrong during trials. But on the other hand, if it works, this could be the beginning of a new age of sense re-immersion for countless victims of neurological disorders, brain damage, paralysis, and more.

A Brain-Dead Person Just Scored Two Kidneys From Genetically Modified Pigs

After only 23 minutes, he could even pee again!

Researchers at the University of Alabama at Birmingham transplanted kidneys derived from genetically modified pigs into a brain-dead person last year as part of human preclinical trials, Science Daily reported.

Organ transplant from another species recently made big news, a heart from a genetically modified pig was transplanted into a human whose heart condition left with no other option. While the transplant was authorized under compassionate grounds by the U.S. Food and Drug Administration, the idea is catching up with the provider of the organ, Revivicor, already having completed two such trials in dead patients.

As Science Daily explains, genetically modified kidneys have been extensively tested in non-human primate recipients but testing them in humans before clinical trials can also provide important information about the safety and efficacy of the transplanted organs.

Full Story:

The shortage of kidneys is acute and calls for a radical solution to save human lives. Genetically modified pig kidneys could be the answer.

Trapping tiny particles: A versatile tool for nanomanipulation

At just 1/1000th of a millimeter, nanoparticles are impossible to see with the naked eye. But, despite being small, they’re extremely important in many ways. If scientists want to take a close look at DNA, proteins, or viruses, then being able to isolate and monitor nanoparticles is essential.

Trapping these particles involves tightly focusing a to a point that produces a strong electromagnetic field. This beam can hold particles just like a pair of tweezers but, unfortunately, there are natural restrictions to this technique. Most notable are the size restrictions—if the particle is too small, the technique won’t work. To date, optical tweezers have been unable to hold particles like individual proteins, which are only a few nanometers in diameter.

Now, due to recent advances in nanotechnology, researchers in the Light-Matter Interactions for Quantum Technologies Unit at the Okinawa Institute of Science and Technology Graduate University (OIST) have developed a technique for precise nanoparticle trapping. In this study, they overcame the natural restrictions by developing optical tweezers based on —a synthetic material with specific properties that do not occur naturally. This was the first time that this kind of metamaterial had been used for single nanoparticle trapping.

U.S. Energy-Related Carbon Dioxide Emissions Expected to Increase in 2022 & 2023

In our latest Short-Term Energy Outlook, we forecast that U.S. energy-related carbon dioxide (CO2) emissions will increase in both 2022 and 2023 but remain below 2019 levels. In 2020, U.S. energy-related CO2 emissions decreased by 11% as energy use declined during the onset of the COVID-19 pandemic. As the U.S. economy began to return to pre-COVID activity, CO2 emissions increased by an estimated 6% in 2021. We expect increasing economic activity, along with other factors, will result in those emissions increasing by another 2% in 2022 and remaining virtually flat in 2023.

We forecast that, by 2023, U.S. energy-related CO2 emissions will total 4,971 million metric tons (MMmt) — still 3% below the 5,144 MMmt of CO2 emissions generated in 2019 and 17% below the peak level of 6,016 MMmt in 2007.

U.S. petroleum-related CO2 emissions increased 8% in 2021, and we forecast that they will increase by another 5% in 2022 and an additional 1% in 2023 as travel activity continues to increase. We forecast that in 2022, the number of vehicle miles traveled in the United States, which affects motor gasoline and diesel consumption, will return to 2019 levels and that air travel will increase by 4% over 2019.
