Kar-go Autonomous Vehicle Begins Contactless Delivery to Care Homes:

Understanding how matter interacts with light—its optical properties—is critical in a myriad of energy and biomedical technologies, such as targeted drug delivery, quantum dots, fuel combustion, and cracking of biomass. But calculating these properties is computationally intensive, and the inverse problem—designing a structure with desired optical properties—is even harder.

Now Berkeley Lab scientists have developed a machine learning model that can be used for both problems—calculating of a known structure and, inversely, designing a structure with desired optical properties. Their study was published in Cell Reports Physical Science.

“Our model performs bi-directionally with high accuracy and its interpretation qualitatively recovers physics of how metal and dielectric materials interact with light,” said corresponding author Sean Lubner.

Longevity biotech firm BioAge Labs is readying itself for clinical trials after raising a whopping $90 million Series C funding round. The company revealed it will be moving its lead platform-derived therapies, BGE-117 and BGE-175, into Phase 2 clinical trials in the first half of 2021.

Longevity. Technology: As the developer of an AI platform that maps the molecular pathways impacting human Longevity, we’ve followed developments at BioAge with great interest. With two compounds ready to enter the clinic next year, and more on the way, this company is fast-becoming one of Longevity’s most exciting prospects.

The new funds will be used to develop BioAge’s portfolio of therapies for increasing healthspan and lifespan, as well as to augment its AI platform, and further expand its capabilities to test drug candidates in predictive models of human diseases of aging.

Space exploration company SpaceX’s founder and chief executive officer Elon Musk on Tuesday said he expected humans to land on Mars in six years. He also said that SpaceX plans to launch an unmanned spacecraft and land on Mars in two years, with a chance of the first human landing on Mars in four years instead of six.

United States’ space agency NASA’s Perseverance rover which was launched in July 2020 is scheduled to land at Jezero Crater on Mars on 18 February 2021. It will look at signs of ancient life and collect rock and soil samples for a possible return to Earth.

It is carrying instruments that will use high-temperature electrolysis but the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) will be producing oxygen only, from the carbon dioxide in the air.

A new type of energy-generating synthetic skin could create more affordable prosthetic limbs and robots capable of mimicking the sense of touch, scientists say.

In an early-view paper published in the journal IEEE Transactions on Robotics, researchers from the University of Glasgow describe how a wrapped in their flexible solar is capable of interacting with objects without using dedicated and expensive .

Instead, the skin puts the array of miniaturized integrated on its soft polymer surface to a clever dual use. The cells generate enough energy to power the micro-actuators which control the hand’s movements, but they also provide the hand with its unique sense of ‘touch’ by measuring the variations in the solar cells’ output.

Diseases caused by folded proteins in the body are all over the news every day, like cancer, Alzheimer’s, and COVID-19. And now, a Google model powered by artificial intelligence could map these folded proteins in more detail than ever before, allowing scientists to “unfold” proteins and better explore possible treatments.
