The prize was awarded half to Roger Penrose for showing how black holes could form and half to Reinhard Genzel and Andrea Ghez for discovering a supermassive object at the Milky Way’s center.
Researchers from the University of Iowa may have discovered a safe new way to manage blood sugar non-invasively. Exposing diabetic mice to a combination of static electric and magnetic fields for a few hours per day normalizes two major hallmarks of type 2 diabetes, according to new findings published Oct. 6 in Cell Metabolism.
“We’ve built a remote control to manage diabetes,” says Calvin Carter, Ph.D., one of the study’s lead authors and a postdoc in the lab of senior author Val Sheffield, MD, Ph.D., professor of pediatrics, and of ophthalmology and visual sciences at the UI Carver College of Medicine. “Exposure to electromagnetic fields (EMFs) for relatively short periods reduces blood sugar and normalizes the body’s response to insulin. The effects are long-lasting, opening the possibility of an EMF therapy that can be applied during sleep to manage diabetes all day.”
The unexpected and surprising discovery may have major implications in diabetes care, particularly for patients who find current treatment regimens cumbersome.
In 2020, slavery is not gone from this planet…
Ira Pastor, ideaXme life sciences ambassador, interviews Bakary Tandia, Co-Founder of the Abolition Institute, a group working to promote awareness of, and dedicated to ending, the practice of slavery in the west African country of Mauritania.
Slavery and enslavement are defined of the state and condition of being a slave, where the individual cannot quit their service to another person and is treated like property.
Terahertz light pulses change gene expression in stem cells, report researchers from Kyoto University’s Institute for Integrated Cell-Material Sciences (iCeMS) and Tokai University in Japan in the journal Optics Letters. The findings come thanks to a new tool, with implications for stem cell research and regenerative therapy development.
Terahertz waves fall in the far infrared/microwave part of the electromagnetic spectrum and can be produced by powerful lasers. Scientists have used terahertz pulses to control the properties of solid-state materials. They also have potential for manipulating living cells, as they don’t damage them the way that ultraviolet or infrared light does. Research so far has led to contradictory findings about their effects on cells, possibly because of the way the experiments have been conducted.
ICeMS microengineer Ken-ichiro Kamei and physicist Hideki Hirori worked with colleagues to develop a better tool for investigating what happens when terahertz pulses are shone on human cells. The apparatus overcomes issues with previous techniques by placing cells in tiny microwells that have the same area as the terahertz light.
NASAs Transiting Exoplanet Survey Satellite (TESS) spent nearly a year imaging the northern sky in its search for worlds beyond our solar system. Explore this panorama to see what TESS has found so far.
Familiar stars shine, nebulae glow, and nearby galaxies tantalize in a new panorama of the northern sky assembled from 208 images from NASA’s Transiting Exoplanet Survey Satellite (TESS).

French company Nawa technologies says it’s already in production on a new electrode design that can radically boost the performance of existing and future battery chemistries, delivering up to 3x the energy density, 10x the power, vastly faster charging and battery lifespans up to five times as long.
Nawa is already known for its work in the ultracapacitor market, and the company has announced that the same high-tech electrodes it uses on those ultracapacitors can be adapted for current-gen lithium-ion batteries, among others, to realize some tremendous, game-changing benefits.
It all comes down to how the active material is held in the electrode, and the route the ions in that material have to take to deliver their charge. Today’s typical activated carbon electrode is made with a mix of powders, additives and binders. Where carbon nanotubes are used, they’re typically stuck on in a jumbled, “tangled spaghetti” fashion. This gives the charge-carrying ions a random, chaotic and frequently blocked path to traverse on their way to the current collector under load.
The Nobel Prize in Chemistry has been awarded to Emmanuelle Charpentier and Jennifer A. Doudna for the development of a method for genome editing.

The Japanese carmaker’s North America division will be partnering with Hino USA, a commercial vehicles manufacturer, to produce the “heavy” Class 8 fuel cell truck specifically for the North American market.
The truck itself will be based on the existing Hino XL Series chassis and powered by Toyota’s fuel cell technology.
Toyota is planning to show off the first demonstration vehicle in the first half of 2021, but we still know little about it. The prototype of a prior initiative called Project Portal 2.0 may provide some clues: revealed in 2018, the prototype was a 670 horsepower semi with 1,325 pound-feet of torque and a towing capacity of 80,000 pounds. Its fuel cells gave it a reported range of 300 miles, CNET reports.
