An Army of Microscopic Robots Is Ready to Patrol Your Body

Posted by in categories: robotics/AI, solar power, sustainability

I was so wrong.

Last week, Drs. Marc Miskin*, Itai Cohen, and Paul McEuen at Cornell University spearheaded a collaboration that tackled one of the most pressing problems in microrobotics—getting those robots to move in a controllable manner. They graced us with an army of Pop-Tart-shaped microbots with seriously tricked-out actuators, or motors that allow a robot to move. In this case, the actuators make up the robot’s legs.

AstraZeneca Covid-19 vaccine study is put on hold

Posted by in category: biotech/medical

A large, Phase 3 study testing a Covid-19 vaccine being developed by AstraZeneca and the University of Oxford at dozens of sites across the U.S. has been put on hold due to a suspected serious adverse reaction in a participant in the United Kingdom.

The future of diabetes: Improving islet transplantation

Posted by in categories: biotech/medical, futurism

This year, the U.S. Food and Drug Administration is expected to approve islet transplants as a treatment for people with type 1 diabetes. The transplants, which deliver insulin-making cells to replace those lost to the disease, have been classified as experimental in the United States since they were first performed more than 20 years ago.

Islet transplants hold great promise for treating type 1 diabetes, especially for what’s colloquially known as “brittle diabetes,” in which patients have a lot of difficulty safely managing their blood sugar with insulin injections, said Stanford interventional radiologist Avnesh Thakor, MD, PhD, who conducts research on islet biology and transplantation.

Nearly 1.6 million Americans have type 1 diabetes, and more than 70,000 are likely to be good candidates for islet transplant.

Facebook focuses on smart audio for AR glasses

Posted by in categories: augmented reality, virtual reality

Inspirational speaker and Amazon best-selling author Sanjo Jendayi once said, “Listening doesn’t always equate to hearing. Hearing doesn’t always lead to understanding, but active listening helps each person truly ‘see’ the other.”

Jendayi was providing a little philosophical advice during a motivational speech, and technology was likely the last thing on her mind. But her words in fact might best describe the notion behind groundbreaking advances by the Facebook Reality Labs Research (FRLR) team’s top scientists, programmers and designers.

A post on the FRLR web site last week provided a peek into where the social media giant is heading in the world of augmented reality and virtual reality.

A robot that controls highly flexible tools

Posted by in categories: information science, robotics/AI

How do you calculate the coordinated movements of two robot arms so they can accurately guide a highly flexible tool? ETH researchers have integrated all aspects of the optimisation calculations into an algorithm. A hot-wire cutter will be used, among other things, to develop building blocks for a mortar-free structure.

A newborn moves its arms and hands largely in an undirected and random manner. It has to learn how to coordinate them step by step. Years of practice are required to master the finely balanced movements of a violinist or calligrapher. It is therefore no surprise that the advanced calculations for the optimal movement of two robot arms to guide a tool precisely involve extremely challenging optimisation tasks. The complexity also increases greatly when the tool itself is not rigid, but flexible in all directions and bends differently depending on its position and movement.

The Brain Can Induce Diabetes Remission in Rodents, but How?

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

Summary: Researchers demonstrate how a single injection of fibroblast growth factor 1 (FGF1) can restore blood sugar levels to normal for extended periods in rodent models of type 2 diabetes. Studies show how FGF1 affects specific neurons and perineuronal nets to help restore blood sugar levels to normal, thus sending diabetes into remission.

In rodents with type 2 diabetes, a single surgical injection of a protein called fibroblast growth factor 1 can restore blood sugar levels to normal for weeks or months. Yet how this growth factor acts in the brain to generate this lasting benefit has been poorly understood.

Bursting Earth’s Bubble

Posted by in categories: information science, robotics/AI, space

An alert pops up in your email: The latest spacecraft observations are ready. You now have 24 hours to scour 84 hours-worth of data, selecting the most promising split-second moments you can find. The data points you choose, depending on how you rank them, will download from the spacecraft in the highest possible resolution; researchers may spend months analyzing them. Everything else will be overwritten like it was never collected at all.

These are the stakes facing the Scientist in the Loop, one of the most important roles on the Magnetospheric Multiscale, or MMS, mission team. Seventy-three volunteers share the responsibility, working weeklong shifts at a time to ensure the very best data makes it to the ground. It takes a keen and meticulous eye, which is why it’s always been left to a carefully-trained human – at least until now.

A paper published recently in Frontiers in Astronomy and Space Sciences describes the first artificial intelligence algorithm to lend the Scientist in the Loop a (virtual) hand.

Men may have a slower immune response to the coronavirus than women, and that could explain their higher mortality rates

Posted by in category: biotech/medical

Men’s delayed immune-system responses to the coronavirus could put them at higher risk of dying from COVID-19 than women, according to a study from University of Washington researchers. They found that, for women under the age of 60, their immune systems produced a near immediate defense against the virus. However, for men of all ages, it took an average of three days for their bodies to deploy T cells (white blood cells that sense and destroy virus-infected cells) to fight the novel coronavirus. note: estrogen and progesterone are in clinical trials as treatment, along with over 300 drugs.


It took three days for men infected with COVID-19 to develop immune system responses, while women’s bodies began to fight the virus right away.
