Working with the tiniest magnets, Hebrew University discovers a new magnetic phenomenon with industrial potential.

For physicists, exploring the realm of the very, very small is a wonderland. Totally new and unexpected phenomena are discovered in the nanoscale, where materials as thin as 100 atoms are explored. Here, nature ceases to behave in a way that is predictable by the macroscopic law of physics, unlike what goes on in the world around us or out in the cosmos.

Dr. Yonathan Anahory at Hebrew University of Jerusalem (HU)’s Racah Institute of Physics led the team of researchers, which included HU doctoral student Avia Noah. He spoke of his astonishment when looking at images of the magnetism generated by nano-magnets, “it was the first time we saw a magnet behaving this way,” as he described the images that revealed the phenomenon of “edge magnetism.”

New treatment options for neuronal diseases require better imaging techniques that will help find which patients will benefits from these treatments.

Scientists were looking at how humans in southeast Asia today have some genes of an ancient human species mostly recorded in Siberia.

When researchers simulated the exhaust from a Falcon 9 rocket launch, they found that it releases high concentrations of CO₂ in the upper atmosphere.

Teslas are among the most susceptible vehicles to be hacked due to their Bluetooth locks, cybersecurity firm NCC Group said. The cars can be remotely unlocked and controlled by hackers that can exploit a vulnerability in the Bluetooth system’s security, the group said.

NCC Group researcher Sultan Qasim Khan was shown in a video opening, then driving a Tesla using a small relay device attached to a laptop. The device bridged a large gap between the Tesla and the Tesla owner’s phone, Reuters said.

“This proves that any product relying on a trusted BLE connection is vulnerable to attacks even from the other side of the world,” NCC said in a statement. BLE means Bluetooth Low Energy, and is a technology utilized in vehicles and Bluetooth locks that will automatically unlock or unlatch when an authorized device is nearby. While it is a convenience feature, it is not immune to attacks, which was the point of NCC’s experiment.

The reason the Falcon Heavy hasn’t flown in about 3 years is that the Falcon 9 ended up having about twice the capacity that was planned for and so the Falcon 9 took away many missions from the Falcon Heavy. (There will finally be some more Falcon Heavy missions later this year…)

Anyway, SpaceX has again increased the capacity of the Falcon 9. They have changed certain timings during flight like igniting the MVac engine a few seconds earlier than on other missions and are separating the fairing closer to stage separation to shed dead weight earlier in the flight.

Every time a new cancer drug is announced, it represents hundreds of researchers spending years behind the scenes working to design and test a new molecule. The drug has to be not only effective, but also as safe as possible and easy to manufacture—and these researchers have to choose among thousands of possible options for its chemical structure.

But building each possible molecular structure for testing is a laborious process, even if researchers simply want to change a single carbon atom.

A new technique published by University of Chicago chemists and the pharmaceutical company Merck & Co. in the journal Science offers a way to leapfrog that process, allowing scientists to quickly and easily produce new molecules of interest.

In biological evolution, we know that it’s all about the survival of the fittest: organisms that develop genetic traits that allow them to better adapt to their physical environment are more likely to thrive, and thus pass down their winning genes to their offspring.

From the longer-beaked Galapagos Island finches studied by biologist Charles Darwin that enabled them to more effectively snatch insects, to the ability of some humans over others to digest milk, the process of natural selection results in genetic differences that give some organisms an edge over others.

New research by University of Toronto Mississauga biology assistant professor Alex N. Nguyen Ba adds an important dimension to our understanding of how genes interact in the evolutionary process.
