Scientists develop deep learning-based biosensing platform to better count viral particles

Posted by in categories: bioengineering, biotech/medical, particle physics, robotics/AI

Recent studies have found that Gires-Tournois (GT) biosensors, a type of nanophotonic resonator, can detect minuscule virus particles and produce colorful micrographs (images taken through a microscope) of viral loads. But they suffer from visual artifacts and non-reproducibility, limiting their utilization.

In a recent breakthrough, an international team of researchers, led by Professor Young Min Song from the School of Electrical Engineering and Computer Science at Gwangju Institute of Science and Technology in Korea, has leveraged artificial intelligence (AI) to overcome this problem. Their work was published in Nano Today.

Rapid and on-site diagnostic technologies for identifying and quantifying viruses are essential for planning treatment strategies for infected patients and preventing further spread of the infection. The COVID-19 pandemic has highlighted the need for accurate yet decentralized that do not involve complex and time-consuming processes needed for conventional laboratory-based tests.

IGF 2023 WS #356 Encryption’s Critical Role in Safeguarding Human Rights

Posted by in categories: biotech/medical, encryption, governance, information science, internet, policy

Two types of technologies could change the privacy afforded in encrypted messages, and changes to this space could impact all of us.

On October 9, I moderated a panel on encryption, privacy policy, and human rights at the United Nations’s annual Internet Governance Forum. I shared the stage with some fabulous panelists including Roger Dingledine, the director of the Tor Project; Sharon Polsky, the president of the Privacy and Access Council of Canada; and Rand Hammoud, a campaigner at Access Now, a human rights advocacy organization. All strongly believe in and champion the protection of encryption.

I want to tell you about one thing that came up in our conversation: efforts to, in some way, monitor encrypted messages.

Policy proposals have been popping up around the world (like in Australia, India, and, most recently, the UK) that call for tech companies to build in ways to gain information about encrypted messages, including through back-door access. There have also been efforts to increase moderation and safety on encrypted messaging apps, like Signal and Telegram, to try to prevent the spread of abusive content, like child sexual abuse material, criminal networking, and drug trafficking.

Canalys Newsroom — North American smartphone shipments to fall 12% in 2023 despite premium segment strength

Posted by in categories: biotech/medical, mobile phones, robotics/AI

Smartphone sales have had their worst quarterly performance in over a decade, a fact that raises two big questions. Have the latest models finally bored the market with mere incremental improvements? And if they have, what will the next form factor (and function) be? Today a deep tech startup called Xpanceo is announcing $40 million in funding from a single investor, Opportunity Ventures in Hong Kong, to pursue its take on one of the possible answers to that question: computing devices in the form of smart contact lenses.

The company wants to make tech more simple, and it believes the way to do that is to make it seamless and more connected to how we operate every day. “All current computers will be obsolete [because] they’re not interchangeable,” said Roman Axelrod, who co-founded the startup with material scientist and physicist Valentyn S. Volkov. “We are enslaved by gadgets.”

With a focus on new materials and moving away from silicon-based processing and towards new approaches to using optoelectronics, Xpanceo’s modest ambition, Axelrod said in an interview, is to “merge all the gadgets into one, to provide humanity with a gadget with an infinite screen. What we aim for is to create the next generation of computing.”

Bird flu now sweeping the world evolved in Europe and Africa

Posted by in category: biotech/medical

For about 25 years, bird flu viruses typically originated in Asia – but the virus that began spreading in 2021 arose in Europe and Africa.

Valley Fever Is a Growing Fungal Threat to Outdoor Workers

Posted by in categories: biotech/medical, food

I think in order to battle this fungal threat more beneficial fungi could be grown like mosses and other permaculture plants to prevent its spread on the farms.


The disease hits farmworkers and outdoor laborers disproportionately hard.

Arginine Facilitates Metabolic Reprograming to Promote Liver Cancer Growth

Posted by in category: biotech/medical

A recent publication in Cell demonstrates that arginine, an amino acid that facilitates various cellular processes, including cellular growth, also promotes tumor growth. The study shows that arginine reprograms the metabolism of the tumor, a mechanism that many cancer cells use to replicate continuously.

The liver’s primary functions include metabolizing nutrients obtained from food and storing energy for later use by the body. Thus, the liver is highly involved in the body’s metabolic balance.

Over the past two decades, a growing body of evidence suggests cancer is a metabolic disease. Almost all cancers, regardless of the tissue in which they develop, have an impairment in energy metabolism.
