SpaceX will launch Masten’s first lander to the moon in 2022

Posted by in category: space travel

SpaceX has secured a contract to act as the launch partner for Masten Space Systems, one of the companies awarded a NASA launch contract under that agency’s Commercial Lunar Payload Services (CLPS) program. Masten’s first lunar mission is set to take place in 2022 if all goes to plan, and will take the company’s XL-1 lunar lander to the south pole of the moon with NASA payloads on board, including scientific experimentation instruments, as well as cargo from commercial passengers.

NASA’s CLPS program is part of its broader efforts to expand partnerships with commercial space companies in order to ultimately lower its costs by sharing providers with other customers from private industry and commercial ventures. It’s also a key staging component for NASA’s Artemis program, which ultimately aims to put the first American woman and the next American man on the surface of the moon by 2024.

The science equipment on Masten’s lander will help the agency study the lunar south pole by gathering key data about the area. NASA’s Artemis III mission will aim to land in the same part of the moon’s surface, and CLPS landers will help it to be informed about the conditions and prepared with resources left in place by some of the uncrewed landers.

YouTube removes record number of videos after increasing role of AI in content review

Posted by in category: robotics/AI

YouTube says it took down a record number of videos in the second quarter of this year due to an increased use of AI in its content review efforts.

In total, 10.85 million of the 11.4 million videos removed from the platform between April and June were flagged by automated systems, according to YouTube‘s latest Community Guidelines Enforcement Report.

AI played an even bigger role in the removal of user comments. Of the 2.1 million comments taken down, 99.2% were detected by automated systems.

Body fat transformed by CRISPR gene editing helps mice keep weight off

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

White fat cells can be turned into energy-burning brown fat using CRISPR gene-editing technology. These engineered cells have helped mice avoid weight gain and diabetes when on a high-fat diet, and could eventually be used to treat obesity-related disorders, say the researchers behind the work.

Human adults have plenty of white fat, the cells filled with lipid that make up fatty deposits. But we have much smaller reserves of brown fat cells, which burn energy as well as storing it. People typically lose brown fat as they age or put on weight. While brown fat seems to be stimulated when we are exposed to cold temperatures, there are no established methods of building up brown fat in the body.

Microsoft researcher Dr. Cecily Morrison will discuss keeping AI ‘personal’ at Sight Tech Global

Posted by in category: robotics/AI

For Dr. Cecily Morrison, research into how AI can help people who are blind or visually disabled is deeply personal. It’s not only that the Microsoft Principal Researcher has a 7-year-old son who is blind, she also believes that the powerful AI-related technologies that will help people must themselves be personal, tailored to the circumstances and abilities of the people they support.

We will see new AI techniques that will enable users to personalize experiences for themselves,” says Dr. Morrison, who is based at Microsoft Research Cambridge and whose work is centered on human-computer interaction and artificial intelligence. “Everyone is different. Having a disability label does not mean a person has the same needs as another with the same label. New techniques will allow people to teach AI technologies about their information needs with just a few examples in order to get a personalized experience suited to their particular needs. Tech will become about personal needs rather than disability labels.”

White House announces creation of AI and quantum research institutes

Posted by in categories: quantum physics, robotics/AI, security

🤔 “The White House today detailed the establishment of 12 new research institutes focused on AI and quantum information science. Agencies including the National Science Foundation (NSF), U.S. Department of Homeland Security, and U.S. Department of Energy (DOE) have committed to investing tens of millions of dollars in centers intended to serve as nodes for AI and quantum computing study.

Laments over the AI talent shortage in the U.S. have become a familiar refrain. While higher education enrollment in AI-relevant fields like computer science has risen rapidly in recent years, few colleges have been able to meet student demand due to a lack of staffing. In June, the Trump administration imposed a ban on U.S. entry for workers on certain visas — including for high-skilled H-1B visa holders, an estimated 35% of whom have an AI-related degree — through the end of the year. And Trump has toyed with the idea of suspending the Optional Practical Training program, which allows international students to work for up to three years in the U.S.”


The White House announced the creation of AI and quantum research institutes funded by billions in venture and taxpayer dollars.

Progress towards a cure for herpes

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

Researchers at the Fred Hutchinson Cancer Research Center in Seattle, USA, have used gene editing to remove latent herpes simplex virus 1 (HSV-1), also known as oral herpes.

In mice, the technique showed a 92% decrease in the latent virus – enough to keep the infection from coming back, according to the scientists. The study used two sets of “genetic scissors” to damage the virus’s DNA, fine-tune a delivery vehicle to the infected cells, and target the nerve pathways connecting the neck with the face, reaching the tissue where the virus lies dormant. The findings are published in Nature Communications.

“This is the first time that scientists have been able to go in and actually eliminate most of the herpes in a body,” said senior author Dr. Keith Jerome, Professor in the Vaccine and Infectious Disease Division at Fred Hutch. “We are targeting the root cause of the infection: the infected cells where the virus lies dormant and are the seeds that give rise to repeat infections.”

The Astrobiology of Alien Worlds

Posted by in category: alien life

A comprehensive review of life as we know it—and may not know it.

In a new paper just published in the journal Universe, Louis Irwin and I attempt to sum up scientists’ current understanding of life “as we know it,” and speculate how life may look and function on alien planets and moons. That includes potential biospheres very different from our own, such as a rocky planet with an ice-covered global ocean. Or it might be a barren planet devoid of surface liquids, or a frigid world with abundant liquid hydrocarbons. It could even be a rogue planet with no “host” star, a tidally locked planet, or a so-called Super-Earth. Maybe the biosphere exists only in the planet’s atmosphere.

Can you make AI fairer than a judge? Play our courtroom algorithm game

Posted by in categories: habitats, information science, robotics/AI

As a child, you develop a sense of what “fairness” means. It’s a concept that you learn early on as you come to terms with the world around you. Something either feels fair or it doesn’t.

But increasingly, algorithms have begun to arbitrate fairness for us. They decide who sees housing ads, who gets hired or fired, and even who gets sent to jail. Consequently, the people who create them—software engineers—are being asked to articulate what it means to be fair in their code. This is why regulators around the world are now grappling with a question: How can you mathematically quantify fairness?

This story attempts to offer an answer. And to do so, we need your help. We’re going to walk through a real algorithm, one used to decide who gets sent to jail, and ask you to tweak its various parameters to make its outcomes more fair. (Don’t worry—this won’t involve looking at code!)

60Fe deposition during the late Pleistocene and the Holocene echoes past supernova activity

Posted by in categories: climatology, cosmology, particle physics, space travel

Nearby supernova explosions shape the interstellar medium. Ejecta, containing fresh nucleosynthetic products, may traverse the solar system as a transient passage, or alternatively the solar system may traverse local clouds that may represent isolated remnants of supernova explosions. Such scenarios may modulate the galactic cosmic-ray flux intensity to which Earth is exposed. Varying conditions of the traversed interstellar medium could have impacts on climate and can be imprinted in the terrestrial geological record. Some radionuclides, such as 60 Fe, are not produced on Earth or within the solar system in significant quantities. Their existence in deep-sea sediments demonstrates recent production in close-by supernova explosions with a continued influx of 60 Fe until today.

Nuclides synthesized in massive stars are ejected into space via stellar winds and supernova explosions. The solar system (SS) moves through the interstellar medium and collects these nucleosynthesis products. One such product is 60 Fe, a radionuclide with a half-life of 2.6 My that is predominantly produced in massive stars and ejected in supernova explosions. Extraterrestrial 60 Fe has been found on Earth, suggesting close-by supernova explosions ∼2 to 3 and ∼6 Ma. Here, we report on the detection of a continuous interstellar 60 Fe influx on Earth over the past ∼33,000 y. This time period coincides with passage of our SS through such interstellar clouds, which have a significantly larger particle density compared to the local average interstellar medium embedding our SS for the past few million years. The interstellar 60 Fe was extracted from five deep-sea sediment samples and accelerator mass spectrometry was used for single-atom counting.
