First demonstration of antimatter wave interferometry
Posted by Quinn Sena in categories: particle physics, quantum physics
Matter waves constitute a crucial feature of quantum mechanics, in which particles have wave properties in addition to particle characteristics. This wave-particle duality was postulated in 1924 by the French physicist Louis de Broglie. The existence of the wave property of matter has been successfully demonstrated in a number of experiments with electrons and neutrons, as well as with more complex matter, up to large molecules.
For antimatter, the wave-particle duality has also been proven through diffraction experiments. However, researchers of the QUPLAS collaboration have now established wave behavior in a single positron (antiparticle to the electron) interference experiment. The results are reported in Science Advances.
The QUPLAS scientific collaboration includes researchers from the University of Bern and from the University and Politecnico of Milano. To demonstrate the wave duality of single positrons, they performed measurements with a setup similar to the so-called double-slit experiment. This setup was suggested by physicists including Albert Einstein and Richard Feynman; it is often used in quantum theory to demonstrate the wave nature of particles.

Algorithms help spot cancer ‘lottery winners’ in new Fred Hutch study
Posted by Genevieve Klien in categories: biotech/medical, information science, robotics/AI
For most patients, a diagnosis of stage 4 non-small cell lung cancer comes with a dire prognosis. But for patients with specific mutations that cause the disease, there are potentially life-saving therapies.
The problem is that these mutations, known as ALK and EGFR, are not always identified in patients — meaning they never get the treatment.
A new study from the Fred Hutchinson Cancer Research Center in Seattle used machine learning to find these needle-in-a-haystack patients. The idea was to leverage cancer databases to see if patients were being tested for the mutations and receiving these personalized treatments.

99-million-year-old, unknown millipede found trapped in Burmese amber
Posted by Genevieve Klien in category: evolution
Scientist now have to reevaluate what they know – or thought they knew – about the evolution of millipedes due to a tiny, 8.2-mm member of the order Callipodida who got its many feet stuck in some tree resin, which turned up in Myanmar, 99 million years later, as a golden lump of amber.

A pill to turn back time

AM I Wrong for wondering about Metformin and its true benefits against the Senesonic-Sensonic pandemic Plague mankind has called aging??? Metformin has been in use truly since the 1920’s and we have not found today an elderly person who is living 125 or 150 years who states they merely took metformin for diabetes??? Now Met has proven itself as a resistant against diabetes due to preventing the liver from making to much glucose that then enters the body. But is it a Longevity drug for mankind is the burning question??? You be the Judge… {I found this link on Antonei Benjamin Csoka group page on the book of faces} Respect r.p.berry & AEWR wherein we have found the causes and a cure for the Pandemic plague mankind has called aging… https://we search for partners and investors to join us in agings end…
Does it make sense to treat ageing as a disease?

Artificial Intelligence Can Now Copy Your Voice: What Does That Mean For Humans?
Posted by Genevieve Klien in category: robotics/AI
Artificial intelligence is a powerful tool. It has become so sophisticated that it can create artificial voices that sound like real voices. It is being used in many ways today to create audio for products, digital assistants and more.

5,000 Years in The Making
Posted by Genevieve Klien in categories: climatology, health, sustainability
Dear Colleagues.
ReWheel, Inc. was founded to save energy based on a simple truth that wasting energy is extremely not smart … as well as very damaging to our planet’s health.
Most of us are either scientists or believe in science. And that is how we know that we are losing the war against climate change. This war will not be won by any one technology but by our combined efforts. To protect our planet for our children and their children, and those who comes after, we need to act.
