A quantum metasurface that can simultaneously control multiple properties of light

Posted by in categories: nanotechnology, particle physics, quantum physics

:oooo.


Metasurfaces are artificial materials designed at the nanoscale, which can control the scattering of light with exceptionally high precision. Over the past decade or so, these materials have been used to create a variety of technological tools ranging from sensors to lenses and imaging techniques.

A research team led by Mikhail Lukin at Harvard University has recently proposed a new type of metasurface that can control both the spatiotemporal and of transmitted and reflected . In a paper published in Nature Physics, the team showed that realizing a quantum metasurface is possible and could be achieved by entangling the macroscopic response of thin atom arrays to light.

‘Exciting’ anti-cancer compound discovered in the humble willow

Posted by in category: biotech/medical

More than a century after giving the world aspirin, another potential drug has been found in the stem and leaves of willows—this time with anti-cancer properties.

Scientists led from Rothamsted Research, working with biologists at the University of Kent have discovered the chemical, miyabeacin, which has been found to kill various cancer , including those resistant to other drugs.

Of particular excitement is its activity against neuroblastoma, a hard to treat and common childhood cancer where the overall survival rate is below 50%.

Ventilator Safety

Posted by in categories: biotech/medical, health

Guide and considerations.


Often changes to mechanical ventilator settings are performed by health care providers that have limited training in specific functions of the ventilator in use. Mechanical ventilators are sophisticated and require training to ensure positive outcomes and harm. Inappropriate setting changes, failure to change alarms, changing settings without appropriate orders, and failure to communicate changes to the medical team can result in poor patient outcomes. This activity is intended to guide health professionals to ensure that all personnel trained are trained to set up, install, and make appropriate adjustments to mechanical ventilation. an interprofessional approach with communication between all members of the healthcare team will result in the safest delivery of care and produce the best outcomes.

Super Ethan Gets A Bionic Arm!

Posted by in categories: cyborgs, transhumanism

Meet 7-year-old Ethan, who received his bionic Hero Arm yesterday at the Hanger Clinic in Aurora, Illinois. Ethan contracted sepsis shortly after his second birthday and he was given a five per cent chance of survival, but the superhero in him fought and survived. Stay strong, Ethan, and may the Force be with you! ✨ 😍 💪 #EthanStrong

Sweden: 22 Scientists Say Coronavirus Strategy Has Failed As Deaths Top 1,000

Posted by in categories: biotech/medical, health

I felt uneasy about the Swedish coronavirus plan the moment I heard about it. It seemed like an extreme gamble, in defiance of all known science and health recommendations. We have Red States here in America that have taken this same approach. Here’s the latest on Sweden: 🇸🇪 —“In an opinion piece published today in Dagens Nyheter, the group of researchers from a range of top Swedish universities and research institutes make harsh criticism of the Swedish Public Health Agency and their present coronavirus strategy. They say that elected politicians must now intervene with ” swift and radical measures.”

“According to Aftonbladet, Jan Lötvall, a professor at the University of Gothenburg, said that Swedish people have not understood the seriousness of the situation because they have received unclear messaging from health authorities and elected officials.”


Sweden’s relatively relaxed approach to controlling the spread of the coronavirus has come under fire in international media and from many locals in the capital Stockholm, where more than half the country’s deaths have been recorded. Now, 22 researchers have publicly criticized the strategy and called on politicians to make changes.

Coronavirus: Fear of reinfection grows after 124 South Koreans test positive for second time

Posted by in category: biotech/medical

Well, that number doubled overnight…


South Korea has identified a growing number of people who make an apparent recovery from the coronavirus only to test positive again, raising fears that the virus is capable of striking the same.

We Need To Reset This Economy

Posted by in category: economics

The one thing we can say at this point in time. China cannot be the manufacturing center for the world. Simply, China has failed and the New World Order Economy has to come to an end.

You cannot continue to accept the lies coming out of the Chinese Communist Party. You can no longer accept that the CCP will tell the truth to its trading partners. China simply lacks the honor and the respect to safely manufacture products for their trading partners and they cannot be trusted with common and necessary safety protocols. Simply, that ship has sailed away, and as a culture, they are not going to change.

Researchers solve puzzle of Compton scattering: New approach for testing theories in quantum mechanics

Posted by in categories: particle physics, quantum physics, space

When the American physicist Arthur Compton discovered that light waves behave like particles in 1922, and could knock electrons out of atoms during an impact experiment, it was a milestone for quantum mechanics. Five years later, Compton received the Nobel Prize for this discovery. Compton used very shortwave light with high energy for his experiment, which enabled him to neglect the binding energy of the electron to the atomic nucleus. Compton simply assumed for his calculations that the electron rested freely in space.

During the following 90 years up to the present, numerous experiments and calculations have been carried out with regard to Compton scattering that continually revealed asymmetries and posed riddles. For example, it was observed that in certain experiments, seemed to be lost when the motion energy of the electrons and light particles (photons) after the collision were compared with the energy of the photons before the collision. Since energy cannot simply disappear, it was assumed that in these cases, contrary to Compton’s simplified assumption, the influence of the on the photon-electron collision could not be neglected.

For the first time in an impact experiment with photons, a team of physicists led by Professor Reinhard Dörner and doctoral candidate Max Kircher at Goethe University Frankfurt has now simultaneously observed the ejected electrons and the motion of the nucleus. To do so, they irradiated helium atoms with X-rays from the X-ray source PETRA III at the Hamburg accelerator facility DESY. They detected the ejected and the charged rest of the atom (ions) in a COLTRIMS reaction microscope, an apparatus that Dörner helped develop and which is able to make ultrafast reactive processes in atoms and molecules visible.

Folding@home is now 15 times faster than any current supercomputer

Posted by in categories: biotech/medical, supercomputing

By itself, your PC is not anywhere near as powerful as a supercomputer. Don’t worry, neither is mine, or anyone else’s I know. But while none of use have the computing resources to single-handedly unlock the secrets of a virus, there is strength in numbers. As such, the collective efforts of PC users far and wide have propelled the Folding@home project to crunch data at a pace that is 15 times faster than IBM’s Summit, the top supercomputer in the world.

The developers of Folding@home have been posting periodic updates on Twitter, and according to the latest one, the distributed computing project is currently cranking out around 2.4 exaFLOPs of computational power.

With our collective power, we are now at ~2.4 exaFLOPS (faster than the top 500 supercomputers combined)! We complement supercomputers like IBM Summit, which runs short calculations using 1000s of GPUs at once, by spreading longer calculations around the world in smaller chunks! pic.twitter.com/fdUaXOcdFJ April 13, 2020
