A Clemson University faculty member will use an award from the National Science Foundation (NSF) to examine middle school students’ data science knowledge and practices through the lens of social issues and gauge students’ sense of empowerment to positively change communities through data science.

Golnaz Arastoopour Irgens, assistant professor of learning sciences in the Clemson University College of Education, said it is a common misconception that data is neutral or free from the influence of social issues or that data has no effect on social issues. She said it is often the case that technology informed by data science, such as search engines or facial recognition software, has been shown to either reinforce discrimination or mischaracterize minority groups.

Because humans design these forms of technology and many more make decisions based on them,

Google Project Zero security researcher moves to Apple

A researcher who worked for Google’s Project Zero is departing the security team and moving over to Apple, to help the iPhone maker improve the security of iOS and its other operating systems.

Revealed on Twitter on Saturday, Brandon Azad confirmed he was leaving Project Zero in favor of a position at Apple in the following week. He will be joining Apple to “continue my work improving Apple device security.”

Project Zero is Google’s security research team that concentrates on finding security issues and vulnerabilities in software, both in Google’s own products and of other major firms. The team works to improve the security of devices and software the general public uses by pointing out the issues to device producers, before performing an ethical disclosure of its findings.

This includes a collection of zero-click bugs in Apple’s Image I/O framework affecting all of Apple’s major platforms, and

Tesla’s new battery design is ‘brilliant,’ says a top researcher

  • Tesla’s new 4680 battery cell is an “A-plus” design according to Shirley Meng, a scientist from the University of California San Diego.
  • But she added that Tesla can’t achieve is ambitious goals by itself — to get to ten terawatts of worldwide capacity, other players will be required.
  • “The world needs so many batteries,” she said.

Tesla’s Battery Day this week brought big news to the metallurgy and chemical-engineering worlds: the company had developed a new cylindrical battery cell, dubbed the “4680,” that’s much larger than the 2170 cells it’s currently using.

While the 4680 cells remain at the prototyping stage and shouldn’t enter mass production until 2022, CEO Elon Musk and his engineers are confident enough in the new form factor to start rethinking the design of Tesla’s cars, with the 4680 cells becoming a structural feature.

In a nutshell, the new

Understanding how the conditionally approved COVID-19 drug works is key to improving treatments, says researcher — ScienceDaily

Researchers at the University of Alberta have discovered a novel, second mechanism of action by the antiviral drug remdesivir against SARS-CoV-2, according to findings published today in the Journal of Biological Chemistry.

The research team previously demonstrated how remdesivir inhibits the COVID-19 virus’s polymerase or replication machinery in a test tube.

Matthias Götte, chair of medical microbiology and immunology in the Faculty of Medicine & Dentistry, likened the polymerase to the engine of the virus. He said the first mechanism the team identified is like putting diesel fuel into an engine that needs regular gasoline.

“You can imagine that if you give it more and more diesel, you will go slower and slower and slower,” he said.

The newly identified mechanism is more like a roadblock, “so if you want to go from A to B with the wrong fuel and terrible road conditions, you either never reach B
