Neuroscientists at MIT have now identified types of cells that encode distinctive segments of an overall experience — a memory. The brain stores these chunks of memory in the hippocampus They are activated whenever a similar experience takes place, and are distinct from the code that stores detailed memories of a specific location.

One of the strangest effects to arise from the quantum nature of the universe is the Casimir force. This pushes two parallel conducting plates together when they are just a few dozen nanometres apart.
At these kinds of scales, the Casimir force can dominate and engineers are well aware of its unwanted effects. One reason why microelectromechanical machines have never reached their original promise is the stiction that Casimir forces can generate.

A neutron star is the dead husk of a star more massive than the sun, but not large enough to become a black hole upon its demise. These stars are between 10 and 29 solar masses during their active lifetime. When they exhaust their nuclear fuel and go supernova, all that’s left is the ultra-dense collapsed core. We call that a neutron star.
The wild physics inside a neutron star are down to the incredible mass packed into such a small space. A neutron star might have twice the mass of our sun packed into an object just a few miles across. The crush of gravity contorts and squeezes neutrons into unusual configurations, based on the models developed by scientists studying neutron stars.
Scientists currently believe that neutron stars have layers characterized by different configurations of distorted neutron matter. For whatever reason, researchers have decided to name the various structures after pasta. Near the surface there’s gnocchi, which are round bubble-like neutrons. Go a bit deeper, and the pressure forces neutrons into long tubes called spaghetti. Go further down, and you have sheets of neutrons called lasagna. That’s just the start of the Italian-inspired interior of neutron stars.

While the Pentagon is busy developing laser weapons, a small California company claims it has discovered a type of plastic that acts as armor against laser energy. The company stumbled on the material by accident and doesn’t fully understand why it works. Samples have been sent to several United States military labs, which are running tests to see how strong a laser beam the plastic can withstand.
“We’re trying to find out the full magnitude of its capabilities,” says Slava Harlamor, president of Harlamor-Schadeck Company, which developed the material.

The T-55 medium tank took all the best traits of the T-54, but added on a series of upgrades necessary for the crew to survive the penultimate weapon: the atomic bomb.

The U.S. Army is testing a system designed to protect military vehicles smaller than tanks from attacks. The “Iron Curtain” uses a combination of sensors and downward-firing projectiles to stop incoming rockets and missiles from striking vehicles by setting off their shaped charge warheads. The result could be vehicles as small Humvees protected from anti-tank guided weapons.
The proliferation of anti-tank weapons with shaped charges has made the modern battlefield very deadly for any vehicle daring to cross it. High explosive, anti-tank (HEAT) warheads are found on everything from shoulder-fired rocket propelled grenade launchers of the Taliban to Kornet-EM anti-tank guided missiles arming the Russian Army. Defeating them is one of the Army’s top concerns, and a brigade of Abrams tanks equipped with the Israeli Trophy active protection system (APS) is headed to Europe in the near future.

During the Cold War, Vozrozhdeniya Island was a top-secret testing ground for deadly Soviet super-pathogens. Despite over two decades of abandonment, their legacy lives on.
Despite a potential vaccine, the novel coronavirus could return on a seasonal basis, much like the flu, according to Seattle-based company Adaptive Biotechnologies.
That’s one of the reasons Adaptive is teaming up with pharmaceutical giant Amgen, which plans to use Adaptive’s proprietary technology platform to develop therapies to treat the virus.
Adaptive’s CEO Chad Robins says it’s the next big thing in the field of immune sequencing. They will screen blood samples of COVID-19 survivors, then identify which naturally occurring antibodies in the immune system can be used to neutralize the SARS-CoV-2 virus which causes the disease.
German company Nanoflow Cell unveiled a sleek looking fully electric Quant 48Volt at the Geneva Motor Show this year with the goal of the company bringing the first production car in the world to be powered by saltwater. The Quant 48Volt has two tanks of liquid with dissolved metallic salt which gives them opposite charges. The liquid is separated by a membrane where positively charged ions lose an electron generating electricity.
One fill up of the tanks are good for 621 miles (1,000 km) which astonishingly is greater distance our gasoline vehicles can take us. However, to fill up the tank which has the 3x capacity of large SUV will take quite a bit of time but certainly not hours.
The salt water powered vehicle generates 560kW (760HP) and goes 0-60mph in 2.4 seconds.
