We are stepping at the gates of a new era in space exploration, one which will finally incorporate the inner solar system to society’s daily life and economics. The first step is the Moon, and the asteroids will probably follow. The surface of those bodies presents special challenges for human and technological activities as well as resource exploitation. These challenges, which include regolith, extreme thermal amplitude, high energy radiation and surface mineral mixing among others, open the door to new operational approaches. COLMENA is the pathfinder of one such avenue: using swarms of micro-rovers for scientific exploration, resource prospection or, eventually, mining The first COLMENA mission will deploy 5 microrovers (56 grams each) on the Moon surface by the end of this year, flying on board a private spacecraft. In the talk I will briefly explain the context, technical characteristics and objectives of the mission, as well as its future.

A short bio.

Roel van DijnenI did not realize that India still has such a small economy, smaller then Germany and UK 😳

Roel van Dijnen In related news, India has so far stopped Tesla and Starlink from operating in their country. Governments can, and often do, screw up their economy.

Roel van DijnenEric Klien The screwing up part is rather subjective, imagine the effect on earth when countries like India and Nigeria will adopt the same luxurious lifestyle that we have. But then again, Tesla and Starlink are trying to be part of the solution for that also 😉

The bottomless bucket is Karl Marx’s utopian creed: “From each according to his ability, to each according to his needs.” In this idyllic world, everyone works for the good of society, with the fruits of their labor distributed freely — everyone taking what they need, and only what they need. We know how that worked out. When rewards are unrelated to effort, being a slacker is more appealing than being a worker. With more slackers than workers, not nearly enough is produced to satisfy everyone’s needs. A common joke in the Soviet Union was, “They pretend to pay us, and we pretend to work.”

In addition to helping those who in the great lottery of life have drawn blanks, governments should adopt myriad policies that expand the economic pie, including education, infrastructure, and the enforcement of laws and contracts. Public safety, national defense, dealing with externalities are also important. There are many legitimate government activities and there are inevitably tradeoffs. Governing a country is completely different from playing a simple, rigged distribution game.

I love computers. I use them every day — not just for word processing but for mathematical calculations, statistical analyses, and Monte Carlo simulations that would literally take me several lifetimes to do by hand. Computers have benefited and entertained all of us. However, AI is nowhere near ready to rule the world because computer algorithms do not have the intelligence, wisdom, or commonsense required to make rational decisions.

Early detection and identification of pathogenic bacteria in food and water samples are essential to public health. Bacterial infections cause millions of deaths worldwide and bring a heavy economic burden, costing more than 4 billion dollars annually in the United States alone. Among pathogenic bacteria, Escherichia coli (E. coli) and other coliform bacteria are among the most common ones, and they indicate fecal contamination in food and water samples. The most conventional and frequently used method for detecting these bacteria involves culturing of the samples, which usually takes 24 hours for the final read-out and needs expert visual examination. Although some methods based on, for example, the amplification of nucleic acids, can reduce the detection time to a few hours, they cannot differentiate live and dead bacteria and present low sensitivity at low concentrations of bacteria. That is why the U.S. Environmental Protection Agency (EPA) approves no nucleic acid-based bacteria sensing method for screening water samples.

In an article recently published in ACS Photonics, a journal of the American Chemical Society (ACS), a team of scientists, led by Professor Aydogan Ozcan from the Electrical and Computer Engineering Department at the University of California, Los Angeles (UCLA), and co-workers have developed an AI-powered smart bacterial colony detection system using a thin-film transistor (TFT) array, which is a widely used technology in mobile phones and other displays.

The ultra-large imaging area of the TFT array (27 mm × 26 mm) manufactured by researchers at Japan Display Inc. enabled the system to rapidly capture the growth patterns of bacterial colonies without the need for scanning, which significantly simplified both the hardware and software design. This system achieved ~12-hour time savings compared to gold-standard culture-based methods approved by EPA. By analyzing the microscopic images captured by the TFT array as a function of time, the AI-based system could rapidly and automatically detect colony growth with a deep neural network. Following the detection of each colony, a second neural network is used to classify the species.

Tech major Google is reportedly slowing down its hiring processes for the rest of 2022. According to a memo by CEO Sundar Pichai to employees, obtained by The Verge, Google will still support its “most important opportunities”, and focus on hiring engineering, technical and other critical roles.

Until now, Google has remained relatively immune to economic uncertainties, and in fact, its sister brand YouTube did well in Q4 2020 — first year of the Covid-19 pandemic. It was reported that its ad revenue hit $6.9 billion — up by 46% quarter-on-quarter. Pichai, in his memo, also highlights that the company hired approximately 10,000 employees in the second quarter of this year, and has a “number of commitments for Q3”, Pichai said in the memo adding that “Google will pause the hiring process for the rest of the year”.

“For the balance of 2022 and 2023, we’ll focus our hiring on engineering, technical and other critical roles, and make sure the great talent we do hire is aligned with our long-term priorities,” he reportedly wrote in the memo.

Intel ((INTC) — Get Intel Corporation Report ) is the bearer of additional bad news.

The chip giant will give an extra blow to consumers and businesses concerned about the health of the economy. For several weeks in fact, consumers have seen their bills for groceries and other products increase. The price of gasoline at the pump has jumped when they go to fill up their car.

And the situation is not getting any better since inflation remains at its highest for forty years, which should push the Federal Reserve to be even more aggressive in raising rates. However, economists have already warned that this monetary policy would plunge the economy into recession.

The TRISO-X, LLC Fuel Fabrication Facility (TF3) will be the nation’s first High-Assay, Low-Enriched Uranium (HALEU) fuel fabrication facility. TRISO-X is a wholly owned subsidiary of advanced reactor designer X-energy, LLC. TF3 will use uranium enriched between 5% and 20% to produce fuel for advanced and small modular reactors of the future. TF3 will manufacture TRi-structural ISOtropic (TRISO) fuel, an advanced fuel that is tough enough to handle the higher operating temperatures of several advanced reactors under development.

The U.S. Department of Energy (DOE) is supporting the development of TF3 through an award with X-energy, LLC under the Advanced Reactor Demonstration Program (ARDP) 0, which aims to speed the demonstration of advanced reactors through cost-shared partnerships with the U.S. nuclear industry. The design and license application development of TF3 was also supported through an $18M (federal cost share) industry FOA that was awarded to X-energy in 2018. TF3 will initially provide the TRISO fuel for X-energy’s Xe-100 high-temperature gas reactor.

“The TRISO-X Fuel Fabrication Facility represents the intersection of some of DOE’s hard work to bring advanced reactors to commercialization,” said Alice Caponiti, DOE’s Deputy Assistant Secretary for Reactor Fleet and Advanced Reactor Deployment. “We’ve been investing in R&D on TRISO fuels for decades. Now, with funding through ARDP, TF3 will bring the next evolution of nuclear fuel to reality, advancing new nuclear technology, creating new jobs, and supporting the clean energy economy.”
