In Project Apollo, life support was based on carrying pretty much everything that astronauts needed from launch to splashdown. That meant all of the food, air, and fuel. Fuel in particular took up most of the mass that was launched. The enormous three-stage Saturn-V rocket was basically a gigantic container for fuel, and even the Apollo spacecraft that the Saturn carried into space was mostly fuel, because fuel was needed also to return from the Moon. If NASA’s new Orion spacecraft takes astronauts back to the Moon, they’ll also use massive amounts of fuel going back and forth; and the same is true if they journey to a near-Earth asteroid. However, once a lunar base is set up, astronauts will be able use microorganisms carried from Earth to process lunar rock into fuel, along with oxygen. The latter is needed not just for breathing, but also in rocket engines where it mixes with the fuel.

Currently, there are microorganisms available naturally that draw energy from rock and in the process release chemical products that can be used as fuel. However, as with agricultural plants like corn and soy, modifying such organisms can potentially make a biologically-based lunar rock processing much more efficient. Synthetic biology refers to engineering organisms to pump out specific products under specific conditions. For spaceflight applications, organisms can be engineered specifically to live on the Moon, or for that matter on an asteroid, or on Mars, and to synthesize the consumables that humans will need in those environments.

In the case of Mars, a major resource that can be processed by synthetic biology is the atmosphere. While the Martian air is extremely thin, it can be concentrated in a biological reactor. The principal component of the Martian air is carbon dioxide, which can be turned into oxygen, food, and rocket fuel by a variety of organisms that are native to Earth. As with the Moon rocks, however, genetic techniques can make targeted changes to organisms’ capabilities to allow them to do more than simply survive on Mars. They could be made to thrive there.

TEL AVIV — November 18, 2020: In a scientifically verified approach, signalling an important breakthrough in the study of aging, Tel Aviv University and The Sagol Center for Hyperbaric Medicine and Research at Shamir Medical Center announced today that, for the first time in humans, two key biological hallmarks of aging, telomere length shortening, and accumulation of senescent cells, can be reversed. The prospective clinical trial, published in peer-reviewed Journal Aging, utilizes Hyperbaric Oxygen Therapy protocols to demonstrate cellular level improvement in healthy aging adults.

For the first-time a human study shows the reversal in the biology of aging including telomere shortening with Hyperbaric Oxygen Therapy.

AMD’s new RDNA 2 architecture packs something called Infinity Cache, which is a superpower in its fight against the Ampere GPUs.

Hydrogen boron could be used essentially for radiationless portable reactors.

These reactors use gravity and buoyancy to spontaneously circulate the cooling water. Another selling point is the size. WIRED reports that it’s “about the size of two school buses stacked end to end, you could fit around 100 of them in the containment chamber of a large conventional reactor.”

Cerebras Systems and the federal Department of Energy’s National Energy Technology Laboratory today announced that the company’s CS-1 system is more than 10,000 times faster than a graphics processing unit (GPU).

On a practical level, this means AI neural networks that previously took months to train can now train in minutes on the Cerebras system.

Cerebras makes the world’s largest computer chip, the WSE. Chipmakers normally slice a wafer from a 12-inch-diameter ingot of silicon to process in a chip factory. Once processed, the wafer is sliced into hundreds of separate chips that can be used in electronic hardware.

It seems these robots could be used to spy on you from home. 😃

A team of researchers demonstrated that popular robotic household vacuum cleaners can be remotely hacked to act as microphones.

The researchers—including Nirupam Roy, an assistant professor in the University of Maryland’s Department of Computer Science—collected information from the laser-based navigation system in a popular vacuum robot and applied signal processing and deep learning techniques to recover speech and identify television programs playing in the same room as the device.

AI startup RealityEngines. AI changed its name to Abacus.AI in July. At the same time, it announced a $13 million Series A round. Today, only a few months later, it is not changing its name again, but it is announcing a $22 million Series B round, led by Coatue, with Decibel Ventures and Index Partners participating as well. With this, the company, which was co-founded by former AWS and Google exec Bindu Reddy, has now raised a total of $40.3 million.

Leave it to Elon Musk to think of putting life on other planets before we’ve even gone back to the moon.

Musk said the capability of SpaceX’s Starship rockets is “designed to make life multiplanetary,” before eventually building a city on Mars.

Not all scientific claims are equal. How can you tell if a discovery is real?

Extremely massive fundamental particles could exist, but they would seriously mess with our understanding of quantum mechanics.

Handedness—and the related concept of chirality—are double-sided ways of understanding how matter breaks symmetries.
