Picturing Earth: Astronaut Photography In Focus

Posted by in category: space

📾 🌍 For 20 years, humans have lived and worked in Earth orbit on the International Space Station. Astronauts photograph our home planet from space almost daily, contributing to a growing archive of over 3 million Earth observations. How these images benefit science: youtu.be/1TtdOVbWjXo # SpaceStation20th.

DeepMind Introduces Algorithms for Causal Reasoning in Probability Trees

Posted by in categories: information science, robotics/AI

Are you a cutting-edge AI researcher looking for models with clean semantics that can represent the context-specific causal dependencies necessary for causal induction? If so, maybe you should take a look at good old-fashioned probability trees.

Probability trees may have been around for decades, but they have received little attention from the AI and ML community. Until now. “Probability trees are one of the simplest models of causal generative processes,” explains the new DeepMind paper Algorithms for Causal Reasoning in Probability Trees, which the authors say is the first to propose concrete algorithms for causal reasoning in discrete probability trees.

Humans naturally learn to reason in large part through inducing causal relationships from our observations, and we do this remarkably well, cognitive scientists say. Even when the data we perceive is sparse and limited, humans can quickly learn causal structures such as interactions between physical objects, observations of the co-occurrence frequencies between causes and effects, etc.

Team finds path to nanodiamond from graphene

Posted by in categories: chemistry, nanotechnology

Marrying two layers of graphene is an easy route to the blissful formation of nanoscale diamond, but sometimes thicker is better.

While it may only take a bit of heat to turn a treated bilayer of the ultrathin material into a cubic lattice of diamane, a bit of in just the right place can convert few-layer graphene as well.

The otherwise chemically driven process is theoretically possible according to scientists at Rice University, who published their most recent thoughts on making high-quality diamane—the 2-D form of diamond—in the journal Small.

A groundbreaking genetic screening tool for human organoids

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

Many of the fundamental principles in biology and essentially all pathways regulating development were identified in so-called genetics screens. Originally pioneered in the fruit fly Drosophila and the nematode C. elegans, genetic screens involve inactivation of many genes one by one. By analyzing the consequences of gene loss, scientists can draw conclusions about its function. This way, for example, all genes required for formation of a brain can be identified.

Genetic screens can routinely be carried out in flies and worms. In humans, a wealth of knowledge exists about genetic disorders and the consequences of disease-relevant mutations, but their systematic analysis was impossible. Now, the Knoblich lab at IMBA has developed a groundbreaking technique allowing hundreds of to be analyzed in parallel in . They named the new technology CRISPR-LICHT and published their findings in the journal Science.

By using cerebral organoids, a 3D cell culture model for the human developed in JĂŒrgen Knoblich’s group at IMBA, hundreds of mutations can now be analyzed for their role in the using CRISPR-LICHT.

Japan’s Unicharm to sell recycled diapers in 2022

Posted by in category: sustainability

TOKYO — Unicharm, the world’s third largest diaper maker, will turn used diapers into new ones which will come onto the market in 2022.

The Japanese company plans to introduce more than 10 facilities for diaper-to-diaper recycling by 2030, as it bolsters efforts to reduce waste.

Unicharm will begin demonstration experiments and collect used diapers initially in Tokyo. The pulp will be taken out of the diapers at its recycling facilities and turned into recycled pulp via an ozone sterilization system.

Chevrolet readies an electric crate motor for homebuilt EV hotrods

Posted by in categories: sustainability, transportation

I don’t know about you, but I am totally here for the growing trend of putting electric propulsion in classic cars. Much of the pioneering work has been done by small aftermarket shops: Zelectric and EV West in California, Electric Classic Cars in the UK, and so on. But increasingly, OEMs are giving it a go as well. For a while, Jaguar was preparing to sell a (very expensive) conversion kit for its XKE-engined cars, although sadly that has been cancelled. Volkswagen has been working with eClassics on an electric conversion of the Type 1 bus. And here in the US, the annual SEMA show has featured some factory-blessed high voltage hot rods for the last couple of years.

SEMA is going virtual this year, and one of the cars that Chevrolet will show off will be a 1977 K5 Blazer—called the Blazer-E—that previews the company’s new eCrate aftermarket powertrain. The build team traded the Blazer’s huge 6.6L V8, with its meagre 175hp (130kW), for the 200hp (150kW) motor from the Bolt EV, which connects to the Blazer’s four-wheel drive system via a four-speed auto that replaces the original three-speed transmission.

The fuel tank and exhaust also went in the recycling bin, and a 60kWh lithium-ion battery pack was mounted in the Blazer’s cargo area. This is also from the Bolt EV and includes all the wiring and power electronics one needs to manage a modern battery EV powertrain.

FBI warns ransomware assault threatens US healthcare system

Posted by in categories: biotech/medical, cybercrime/malcode

BOSTON (AP) — Federal agencies warned that cybercriminals are unleashing a wave of data-scrambling extortion attempts against the U.S. healthcare system designed to lock up hospital information systems, which could hurt patient care just as nationwide cases of COVID-19 are spiking.

In a joint alert Wednesday, the FBI and two federal agencies warned that they had “credible information of an increased and imminent cybercrime threat to U.S. hospitals and healthcare providers.” The alert said malicious groups are targeting the sector with attacks that produce “data theft and disruption of healthcare services.”

The cyberattacks involve ransomware, which scrambles data into gibberish that can only be unlocked with software keys provided once targets pay up. Independent security experts say it has already hobbled at least five U.S. hospitals this week, and could potentially impact hundreds more.
