Researchers demonstrate room-temperature spin transfer across an interface between an iron-based ferromagnet and a semiconductor, opening a route to creating novel spintronic devices.

The patterns observed in a jet exiting a nozzle are directly related to the size of the nozzle’s opening and to the rate at which water flows.

A mechanism for preventing destructive instabilities in magnetically confined plasmas provides a new way for scientists to operate future nuclear-fusion reactors.

All magnetically confined plasmas naturally develop instabilities, regions where small perturbations grow rapidly [1]. Scientists have been looking for ways to prevent instabilities in a tokamak—a leading candidate for a fusion reactor—because the instabilities can cause substantial damage to the tokamak’s walls. Now Georg Harrer at the Vienna University of Technology and his colleagues have shown how these destructive instabilities can be avoided by adjusting the properties of the plasma and its confining magnetic field [2]. The researchers’ findings offer a fresh approach to running future fusion reactors.

A tokamak uses a powerful magnetic field to confine fusion fuel in the form of a plasma (a highly ionized gas) that is shaped like a ring donut. Instabilities that originate at the plasma edge (the “glaze” of the donut) are called edge-localized modes (ELMs) [3]. ELMs transport heat and particles along magnetic-field lines, moving them from the well-confined plasma core (the “filling” of the donut) to the divertor—a region of the tokamak’s walls. ELMs come in various sizes and frequencies (repetition rates). Their size, expressed as a percentage of the energy stored in the plasma core, strongly influences how much heat and how many particles will be deposited by each ELM in the divertor.

At the age of 14, I was diagnosed with a stage 4 hypermutated glioblastoma and a clinical trial saved my life. Now I’m 18 and cancer-free.

“I was amazed. Although they resemble rings in the image, the true 3D geometry of those semi-circular features is better described as a shell”

In a fresh image released by the Webb Telescope team on October 12, one can see 17 strangely perfect light rings around star binary WR 140 emanating into the darkness of deep space.

Genflow has announced that its adeno-associated virus (AAV) research and development programme in Estonia has received a non-dilutive grant award of €250,000 from the Applied Research Programme of Enterprise Estonia, an Estonian governmental institution designed to stimulate business growth in the country.

Longevity. Technology: Genflow’s research programme is focused on the development of an antiaging gene therapy platform designed to target nearly 100 million patients worldwide who suffer from Werner’s syndrome, non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis, an advanced form of NAFLD, as well as other major clinical disorders.

This R&D is a collaborative project between Genflow and IVEX lab OÜ, an Estonian company specialising in the research and development of biotech therapeutics.

Scientists have transplanted human brain cells into the brains of baby rats, where the cells grew and formed connections.

It’s part of an effort to better study human brain development and diseases affecting this most complex of organs, which makes us who we are but has long been shrouded in mystery.

“Many disorders such as autism and schizophrenia are likely uniquely human” but “the human brain certainly has not been very accessible,” said said Dr. Sergiu Pasca, senior author of a study describing the work, published Wednesday in the journal Nature.

Experimental technology used to cool equipment in space might soon be able to cut the charging times of electric vehicles to five minutes or less, American space agency NASA said this week.

The federal space agency-funded technology, in partnership with Purdue University, says the research they’re planning for future space missions shows its tech could charge an electric car within minutes instead of hours, according to an Oct. 5 blog by NASA.

Using a technique known as “subcooled flow boiling,” the tech could boost the amount of electrical current EV chargers by roughly 1,400 amps, nearly five times the rate of up to 520 amps currently supplied to EVs, NASA said.

Summary: A new artificial intelligence model automatically learns higher-level language patterns that can apply to different languages, enabling it to achieve better results.

Human languages are notoriously complex, and linguists have long thought it would be impossible to teach a machine how to analyze speech sounds and word structures in the way humans do.
