Discoveries of high-Chern-number and high-temperature Chern insulator states

The Quantum Hall effect (QHE) is one of the most important discoveries in physical sciences. Due to the one-dimensional (1-D) dissipationless edge states, QHE exhibits exotic transport properties with quantized Hall resistance of h/νe2 and vanishing longitudinal resistance. Here, h is Planck’s constant, ν is Landau filling factor and e is electron charge. QHE usually originates from the formation of remarkable…

Has mystery of universe’s missing matter been solved?

Cosmologists have only been able to find half the matter that should exist in the universe. With the discovery of a new astronomical phenomenon and new telescopes, these researchers say they’ve just found the rest.

America’s Government Approves Release of Genetically-Engineered Mosquitoes

America’s Environmental Protection Agency “granted permission for genetically engineered mosquitoes to be released into the Florida Keys and around Houston to see if they can help limit the spread of mosquito-borne illnesses,” writes Bloomberg Environment. clovis (Slashdot reader #4,684) shared their report on ab experimental use permit granted to British biotech company Oxitec Ltd:
Oxitec’s first field trial in Brazil achieved up…

Predicting a Post-Pandemic Future: Remote Working and Distance Learning?

This week Politico published predictions from 34 “big thinkers” about what the future will be like after the coronavirus pandemic. (An associate professor of government and politics at the University of Maryland argues that “The Reagan era is over. The widely accepted idea that government is inherently bad won’t persist after coronavirus.”) Others predict a future with voting from mobile devices…

What is dark matter?

Dark matter doesn’t emit light. It can’t be directly observed with any of the existing tools of astronomers. Yet astrophysicists believe it and dark energy make up most of the mass of the cosmos. What dark matter is, and what it isn’t. here. Source: https://earthsky.org/astronomy-essentials/definition-what-is-dark-matter…

Powerful Antibiotic Discovered Using Machine Learning For First Time

A powerful antibiotic that kills some of the most dangerous drug-resistant bacteria in the world has been discovered using artificial intelligence. The Guardian reports: To find new antibiotics, the researchers first trained a “deep learning” algorithm to identify the sorts of molecules that kill bacteria. To do this, they fed the program information on the atomic and molecular features of nearly…

Chemotherapy For Cancer Could Soon Be Unviable Because of Superbugs

schwit1 quotes a report from MSN: Cancer doctors fear superbugs which can’t be treated with antibiotics will soon remove chemotherapy as a treatment option for their patients, a survey has revealed. Cancer patients are more vulnerable to infections because the disease and its treatments can stop the immune system from working correctly. Of the 100 oncologists in the U.K. surveyed between…

The Messy, Secretive Reality Behind OpenAI’s Bid To Save the World

OpenAI has a glossy exterior. In the four short years of its existence, it has catapulted itself to a spot among the leading AI research labs in the world. Part of it is its consistency in producing headline-grabbing research. Part of it is its co-founders Elon Musk and legendary investor Sam Altman. But above all, OpenAI is lionized for its mission….

The Gig Workers For Target’s Delivery App Hate Their Algorithmically-Determined Pay

In 2017 Target bought a same-day home-delivery company called Shipt for $550 million. Shipt now services half of Target’s stores, reports Motherboard, and employs more than 100,000 gig workers. Unfortunately, they’re working for a company that “has a track record of censoring and retaliating against workers for asking basic questions about their working conditions or expressing dissent,” reports Motherboard. For example,…
