Lasers support certain structures of light known as “eigenmodes.” An international collaboration of experts in gravitational waves.

Gravitational waves are distortions or ripples in the fabric of space and time. They were first detected in 2015 by the Advanced LIGO detectors and are produced by catastrophic events such as colliding black holes, supernovae, or merging neutron stars.

Stem cell therapies are showing huge promise in a lot of areas, but one application that has scientists particularly excited is in next-generation treatments for Parkinson’s disease. A team experimenting in this area has demonstrated how implanting carefully cultivated stem cells into rats can bring about remarkable recovery from motor symptoms typical of the disease, and are now setting their sights on upcoming human trials.

Parkinson’s disease is considered a prime target for innovative stem ell therapies because the condition can be traced back to the deterioration of a particular type of cell in a particular region of the brain. The neurons in the substantia nigra, a structure in the midbrain, are responsible for producing dopamine, which helps control movement, among other things.

The loss of these neurons is what contributes to motor symptoms in Parkinson’s patients, so using stem cell therapies to replace them is a very appealing idea, and one that has started to migrate from animal testing to humans. In a world-first trial undertaken in Japan in 2018, Parkinson’s patients had stem-cell-derived precursor cells implanted into their brains where they matured into the dopamine-producing neurons, with a number of subjects reported to be doing well.

A lesson from the Ukraine war is the resiliency provided by large proliferated constellations, said Gen. David Thompson.

WASHINGTON — During a Senate Armed Services Committee hearing May 11, Sen. Tom Cotton (R-Ark.) asked Space Force officials if any lessons could be drawn from the war in Ukraine about the role of commercial satellites in armed conflicts.

One lesson is the resiliency provided by large proliferated constellations, said Gen. David Thompson, vice chief of space operations of the U.S. Space Force.

A recently discovered backdoor malware called BPFdoor has been stealthily targeting Linux and Solaris systems without being noticed for more than five years.

BPFdoor is a Linux/Unix backdoor that allows threat actors to remotely connect to a Linux shell to gain complete access to a compromised device.

The malware does not need to open ports, it can’t be stopped by firewalls, and can respond to commands from any IP address on the web, making it the ideal tool for corporate espionage and persistent attacks.

Elon Musk’s intervention demonstrates how satellite internet could route around war or censorship far beyond Ukraine.

Logic gates are the fundamental building blocks of computers, and researchers at the University of Rochester have now developed the fastest ones ever created. By zapping graphene and gold with laser pulses, the new logic gates are a million times faster than those in existing computers, demonstrating the viability of “lightwave electronics.”

Logic gates take two inputs, compare them, and then output a signal based on the result. They can, for example, output a 1 if both incoming signals are a 1 or a 0, or if either or neither of them is a 1, among other “rules.” Billions of individual logic gates are crammed into chips to create processors, memory and other electronic components.

The ousted staffer said little about Musk’s plans for the company, but he praised his team for the work they did during his seven years at the tech platform.

Researchers at Princeton University have built the world’s smallest mechanically interlocked biological structure, a deceptively simple two-ring chain made from tiny strands of amino acids called peptides.

In a paper published August 23 in Nature Chemistry, the team detailed a library of such structures made in their lab—two interlocked rings, a ring on a dumbbell, a daisy chain and an interlocked double lasso—each around one billionth of a meter in size. The study also demonstrates that some of these structures can toggle between at least two shapes, laying the groundwork for a biomolecular switch.

“We’ve been able to build a bunch of structures that no one’s been able to build before,” said A. James Link, professor of chemical and biological engineering, the study’s principal investigator. “These are the smallest threaded or interlocking structures you can make out of peptides.”
