A teacher allows AI tools in exams — here’s what he learned

Posted by in categories: education, robotics/AI

AI tools are making their way into classrooms: even in schools today, students create texts, presentations, images and translations at the click of a button. How can teachers deal with AI’s new possibilities?

For many teachers, homework, papers and tests raise the question of autonomy. How should they grade exams if it’s not clear who did the work – the examinee or an AI? A common reflex to digital developments in education is to regulate these possibilities, to put digital devices into exam mode without network access, or to ban AI tools.

The Evangelisch Stiftische Gymnasium in Gütersloh, Germany, is taking the opposite approach: laptops and iPads have been widely used there for 20 years. GPT-3 and Co. are being tested in German lessons and are even required for class tests.

Want To Live Longer? How Life Extension Industry Will Reboot Health, Wellness and The Economy

Posted by in categories: economics, life extension

Do you want to live a better, healthier and longer life? Me too.

Lets go back to 1937, when Albert Szent-Györgyi won a Nobel Prize for his discovery of ascorbic acid—vitamin C—that enables the body to efficiently use carbohydrates, fats, and protein (I use it a lot during cold and flu season, you?). It was a massively consequential discovery, as it not only saved and extended countless lives, but it also contributed to the foundations of modern nutrition. Szent-Györgyi, himself, was blessed with a long life; he died in 1986 at the age of 93. But he might just as well be known for what he said on his 90th birthday: “I wish I could be 75 again!”

No doubt, that comment elicits more than a few eyerolls today. Especially since the CDC has recently downgraded American life expectancy to just 77 years. But could 75 someday be the new 40—an age by which, like Szent-Györgyi, we’re only hitting our stride? Well, if the burgeoning activity of the life extension industry is any indication, we may actually be on the cusp of making it so—and enjoying life to the fullest right up to the extended end. Which brings us to the morbid thought of mortality—that end state most of us seek to delay, if not dodge.

Seeking microscopic clues to beating deadly brain tumors

Posted by in categories: innovation, neuroscience

A critical new pathway to treating an aggressive brain tumor might be found in the complex diversity within the tumor tissue, according to a new paper by scientists from the Hackensack Meridian Center for Discovery and Innovation (CDI).

The CDI laboratory deeply analyzed tumor tissue using an advanced mass spectrometry with special focus on lipids, a class of molecules that includes fats, according to the new paper, in the journal Scientific Reports.

“Lipid ions presented here lay the foundation for future studies that are required to understand their interconnecting signaling pathways in relation to , tumor progression, and resistance to therapy,” according to the paper. “Understanding their functional relevance is essential for the identification of new therapeutics based on targets.”

Lockheed Martin’s fusion-powered fighter and bomber plans

Posted by in categories: military, nuclear energy

A fascinating new look at the patents and defense projects in the US Military and its hopefully fusion powered future. (FUSION POWER: Only 20 years away for the last 40 years!! 😉)


Back in 2018, Lockheed Martin filed a patent for something it called a “plasma confinement system” — a device small enough to fit inside the fuselage of an F-16 Fighting Falcon that is capable of managing internal temperatures 10 times hotter than the center of the sun.

NVIDIA Is Making a Digital Twin of Earth’s Climate. Here’s an Inside Look

Posted by in categories: climatology, sustainability

“If I’m a farmer in Australia, and I want to know what the drought situation is going to look like over the next 20 to 30 years and decide what sorts of crops I might want to grow or how I might want to change irrigation technologies that I use for my farm, I want to be able to ask questions like that to this digital twin and get answers,” Kashinath said.

FourCastNet, an open-source project, is the first product of the broader Earth-2 initiative available to researchers. And while there’s no specific date for when the team will launch Earth-2 publicly, Kashinath said it will similarly be open for use by the research community.

Beaming Clean Energy From Space — Caltech’s “Extraordinary and Unprecedented Project”

Posted by in categories: engineering, solar power, space travel, sustainability

Technology capable of collecting solar power in space and beaming it to Earth to provide a global supply of clean and affordable energy was once considered science fiction. Now it is moving closer to reality. Through the Space-based Solar Power Project (SSPP), a team of California Institute of Technology (Caltech) researchers is working to deploy a constellation of modular spacecraft that collect sunlight, transform it into electricity, then wirelessly transmit that electricity wherever it is needed. They could even send it to places that currently have no access to reliable power.

“This is an extraordinary and unprecedented project,” says Harry Atwater, an SSPP researcher and Otis Booth Leadership Chair of Caltech’s Division of Engineering and Applied Science. “It exemplifies the boldness and ambition needed to address one of the most significant challenges of our time, providing clean and affordable energy to the world.”

New Clues Into a Serious Neurodegenerative Disease, Frontotemporal Dementia

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

Summary: A genetic form of frontotemporal dementia is associated with abnormal lipid accumulation in the brain fueled by disrupted cell metabolism. The findings could pave the way for new targeted therapies for FTD.

Source: Harvard.

Dementia encompasses a range of neurodegenerative conditions that lead to memory loss and cognitive deficiencies and affect some 55 million people worldwide. Yet despite its prevalence, there are few effective treatments, in part because scientists still don’t understand how exactly dementia arises on a cellular and molecular level.

‘Like conductive Play-Doh’: breakthrough could point way to a new class of materials for electronic devices.

University of Chicago.

Founded in 1,890, the University of Chicago (UChicago, U of C, or Chicago) is a private research university in Chicago, Illinois. Located on a 217-acre campus in Chicago’s Hyde Park neighborhood, near Lake Michigan, the school holds top-ten positions in various national and international rankings. UChicago is also well known for its professional schools: Pritzker School of Medicine, Booth School of Business, Law School, School of Social Service Administration, Harris School of Public Policy Studies, Divinity School and the Graham School of Continuing Liberal and Professional Studies, and Pritzker School of Molecular Engineering.

Hark back to the late 1990s with this re-creation of the dialup Internet experience

Posted by in categories: biotech/medical, computing, mobile phones

We all found our coping strategies for riding out the pandemic in 2020. Biomedical engineer Gough Lui likes to tinker with tech—particularly vintage tech—and decided he’d try to recreate what it was like to connect to the Internet via dialup back in the late 1990s. He recorded the entire process in agonizing real time, dotted with occasional commentary.

Those of a certain age (ahem) well remember what it used to be like: even just booting up the computer required patience, particularly in the earlier part of the decade, when one could shower and make coffee in the time it took to boot up one’s computer from a floppy disk. One needed a dedicated phone line for the Internet connection, because otherwise an incoming call could disrupt the connection, forcing one to repeat the whole dialup process.
