Giant lasers help re-create supernovas’ explosive, mysterious physics
Posted by Quinn Sena in categories: cosmology, particle physics
Learning the results sparked a moment of joyous celebration, Park says: high fives to everyone.
“This is some of the first experimental evidence of the formation of these collisionless shocks,” says plasma physicist Francisco Suzuki-Vidal of Imperial College London, who was not involved in the study. “This is something that has been really hard to reproduce in the laboratory.”

Meat Grown in Israeli Bioreactors Is Coming to American Diners
Posted by Derick Lee in categories: biotech/medical, futurism
Other companies, including BlueNalu Inc., Upside Foods Inc. and Eat Just, have expressed an intention to sell cell-based products in the U.S. Like them, Future Meat must get approval from the U.S. Department of Agriculture and the Food and Drug Administration before offering its products to the public. Kshuk is optimistic, though reaching price parity with conventional meat will probably take the nascent industry a few years.
An Israeli startup wants to replace chicken coops, barns and slaughterhouses with bioreactors to churn out cell-based meat for American diners.
Future Meat Technologies Ltd. is in talks with U.S. regulators to start offering its products in restaurants by the end of next year. The company has just opened what it calls the world’s first industrial cellular meat facility, which will be able to produce 500 kilograms (1102 pounds) a day.

The World Just Moved Even Closer to a Real, Working Warp Drive
Posted by Quinn Sena in categories: physics, space travel
Scientists have given the all-clear.
Warp drive is having a moment. Just last week, scientists dropped a bombshell when they unveiled the first physical model for a warp drive, the holy grail of space travel that would allow us to bend the fabric of space and time to their will and overcome the vast distances separating humans from the stars. Now, another astrophysicist has delivered an equally exciting warp drive breakthrough.
Up until this point, scientists have slowly chipped away at the fantasy of faster-than-light (FTL) travel by relying on theories of bizarre physics and exotic matter. But in a new paper, Göttingen University’s Erik Lentz has created a theoretical design of a warp drive that’s actually grounded in conventional physics. Lentz’s theory overcomes the need for a source of exotic matter in previous designs by reimagining the shape of warped space.

Archaeologists Make Dramatic Discovery: A Prehistoric Human Type Previously Unknown to Science
Posted by Genevieve Klien in categories: biotech/medical, evolution, science
Two teams of researchers took part in the dramatic discovery, published in the prestigious Science journal: an anthropology team from Tel Aviv University headed by Prof. Israel Hershkovitz, Dr. Hila May and Dr. Rachel Sarig from the Sackler Faculty of Medicine and the Dan David Center for Human Evolution and Biohistory Research and the Shmunis Family Anthropology Institute, situated in the Steinhardt Museum at Tel Aviv University; and an archaeological team headed by Dr. Yossi Zaidner from the Institute of Archaeology at the Hebrew University of Jerusalem.
Timeline: The Nesher Ramla Homo type was an ancestor of both the Neanderthals in Europe and the archaic Homo populations of Asia.

Researchers propose the use of quantum cascade lasers to achieve private free-space communications
Posted by Saúl Morales Rodriguéz in categories: quantum physics, security
Free-space optical communication, the communication between two devices at a distance using light to carry information, is a highly promising system for achieving high-speed communication. This system of communication is known to be immune to electromagnetic interference (EMI), a disturbance generated by external sources that affects electrical circuits and can disrupt radio signals.
While some studies have highlighted the possible advantages of free-space optical communication, this system of communication has so far come with certain limitations. Most notably, it is known to offer limited security against eavesdroppers. Researchers at Télécom Paris (member of Institut Polytechnique de Paris), mirSense, Technische Universität Darmstadt and University of California Los Angeles (UCLA) have recently introduced a unique system for more secure free-space optical communication based on a technology known as quantum cascade laser, a specific type of semiconductor laser that typically emits mid–infrared light.
“The core idea behind our research is that private free-space communication with quantum key distribution (i.e., based on quantum physics properties) is promising, but it is probably years away, or even further,” Olivier Spitz, one of the researchers who carried out the study, told TechXplore. “Currently, the main limitations of this technology are the requirements for cryogenic systems, very slow data rates and costly equipment.”

Researchers create an artificial tactile skin that mimics human tactile recognition processes
Posted by Saúl Morales Rodriguéz in categories: biotech/medical, cyborgs, robotics/AI
Over the past few decades, roboticists and computer scientists have developed artificial systems that replicate biological functions and human abilities in increasingly realistic ways. This includes artificial intelligence systems, as well as sensors that can capture various types of sensory data.
When trying to understand properties of objects and how to grasp them or handle them, humans often rely on their sense of touch. Artificial sensing systems that replicate human touch can thus be of great value, as they could enable the development of better performing and more responsive robots or prosthetic limbs.
Researchers at Sungkyunkwan University and Hanyang University in South Korea have recently created an artificial tactile sensing system that mimics the way in which humans recognize objects in their surroundings via their sense of touch. This system, presented in a paper published in Nature Electronics, uses sensors to capture data associated with the tactile properties of objects.
