A collaboration between researchers from The University of Western Australia and The University of California Merced has provided a new way to measure tiny forces and use them to control objects.

The research, published recently in Nature Physics, was jointly led by Professor Michael Tobar, from UWA’s School of Physics, Mathematics and Computing and Chief Investigator at the Australian Research Council Centre of Excellence for Engineered Quantum Systems and Dr. Jacob Pate from the University of Merced.

Professor Tobar said that the result allowed a new way to manipulate and control macroscopic objects in a non-contacting way, allowing enhanced sensitivity without adding loss.

A team of physicists led by Professor Patrick Windpassinger at Johannes Gutenberg University Mainz (JGU) has successfully transported light stored in a quantum memory over a distance of 1.2 millimeters. They have demonstrated that the controlled transport process and its dynamics has only little impact on the properties of the stored light. The researchers used ultra-cold rubidium-87 atoms as a storage medium for the light as to achieve a high level of storage efficiency and a long lifetime.

“We stored the light by putting it in a suitcase so to speak, only that in our case the suitcase was made of a cloud of cold atoms. We moved this suitcase over a short distance and then took the light out again. This is very interesting not only for physics in general, but also for quantum communication, because light is not very easy to ‘capture’, and if you want to transport it elsewhere in a controlled manner, it usually ends up being lost,” said Professor Patrick Windpassinger, explaining the complicated process.

The controlled manipulation and storage of quantum information as well as the ability to retrieve it are essential prerequisites for achieving advances in quantum communication and for performing corresponding computer operations in the quantum world. Optical quantum memories, which allow for the storage and on-demand retrieval of quantum information carried by light, are essential for scalable quantum communication networks. For instance, they can represent important building blocks of quantum repeaters or tools in linear quantum computing. In recent years, ensembles of atoms have proven to be media well suited for storing and retrieving optical quantum information. Using a technique known as electromagnetically induced transparency (EIT), incident light pulses can be trapped and coherently mapped to create a collective excitation of the storage atoms. Since the process is largely reversible, the light can then be retrieved again with high efficiency.

The planned launch of a private commercial airlock to the International Space Station in November will accelerate NASA’s plan to turn the station into a hub of private industry, space agency officials said.

The commercialization plan also includes the launch of a private habitat and laboratory by 2024 and a project NASA Administrator Jim Bridenstine announced on Twitter in May in which actor Tom Cruise will film a movie in space.

The 20-year-old space station may even have a private citizen on board again for the first time in years in late 2021, according to Phil McAlister, NASA’s director of commercial spaceflight. It’s part of a plan to wean the space station off NASA’s public funding of $3 billion to $4 billion per year.

When it comes to vitamin D, most adults exhibit either frank deficiency, which results in clear clinical symptoms, or insufficiency, which often goes undetected. But how that insufficiency impacts physical health and the vulnerability of older adults to frailty as they age has been difficult to determine.

Now a University at Buffalo study of 24–28–month-old mice, the equivalent of 65-to-80-year-old adults, has found that frailty can be slowed with what might be considered “over” supplementation with vitamin D, referred to as “hypersufficiency.”

Published Sept. 30 in Nutrients, the research builds on previous work that Kenneth L. Seldeen, Ph.D., first author and research assistant professor in the Department of Medicine in the Jacobs School of Medicine and Biomedical Sciences at UB, has been conducting for more than a decade with colleague Bruce R. Troen, MD, professor of medicine and chief of the Division of Geriatrics and Palliative Medicine and director of the Center for Successful Aging, both in the Jacobs School.

A research team from Cologne has discovered that a change in the DNA structure—more precisely in the chromatin—plays a decisive role in the recovery phase after DNA damage. The key is a double occupation by two methyl groups on the DNA packaging protein histone H3 (H3K4me2). The discovery was made by scientists under the direction of Prof. Björn Schumacher of the Cluster of Excellence for Aging Research CECAD, the Center for Molecular Medicine Cologne (CMMC), and the Institute for Genome Stability in Aging and Disease at the University of Cologne. The specific change enables genes to be reactivated and proteins to be produced after damage: The cells regain their balance and the organism recovers. The protective role of H3K4me2 was identified in experiments with the nematode Caenorhabditis elegans. The study has now been published in the journal Nature Structural & Molecular Biology.

The genome in every human cell is damaged on a daily basis, for example in the skin by UV radiation from the sun. Damage to the DNA causes diseases such as cancer, influences development, and accelerates aging. Congenital malfunctions in DNA repair can lead to extremely accelerated aging in rare hereditary diseases. Therefore, preservation and reconstruction processes are particularly important to ensure development and to maintain tissue function. DNA, which is rolled up on packaging proteins—the histones—like on cable drums, is regulated by methyl groups. Various proteins are responsible for placing methyl groups on histones or removing them. The number of groups on the packaging proteins affects the activity of genes and thus the protein production of the cell.

My hero my love.

Last week, Tesla CEO Elon Musk made a rather interesting announcement for all-electric vehicle enthusiasts in India, when he mentioned that Tesla is planning on entering the Indian automobile market in 2021. The announcement comes after years of waiting for the Indians to get their hands on a Tesla, and it definitely has got the public buzzing with excitement. Now, Musk has also stated that Tesla will be coming up with a Booking Order Configurator for the Indian customers which will be going live in January 2021.

If you’ve been a grunt, then you probably have a love-hate relationship with body armor. You love having it in a firefight — it can save your life by stopping or slowing bullets and fragments — but you hate how heavy it is — it’s often around 25 pounds for the armor and outer tactical vest (more if you add the plate inserts to stop up to 7.62mm rounds). It’s bulky — and you really can’t move as well in it. In fact, in one firefight, a medic removed his body armor to reach wounded allies, earning a Distinguished Service Cross.

Elon Musk is among the few people on Earth that are working towards changing the course of humanity’s future in a drastic way. He founded SpaceX in 2002 to make life multiplanetary –colonize Mars. Since then, SpaceX has developed some of the world’s most advanced rockets and spacecraft. Throughout the years Musk’s bold ideas, ambitious goals, and ability to lead teams to achieve greatness has earned him a place in history. Hollywood actor Channing Tatum seems to be inspired by Musk’s space venture that he is now planning to produce an HBO drama television series about Musk and his journey at SpaceX.

According to Deadline reporters, who first reported the news, Tatum’s film production company, Free Association, will produce a six-episode scripted series. The story will be about how SpaceX started with a rocket that almost did not make it to orbit, to returning human spaceflight capabilites to the United States. “The project will be penned by Star Trek Beyond scribe Doug Jung based on Ashlee Vance’s book Elon Musk: Tesla, SpaceX, and the Quest for a Fantastic Future, first published in 2017,” Deadline reports, “Free Association’s Tatum, Reid Carolin and Peter Kiernan will executive produce with Vance and Len Amato, HBO’s former President Of HBO Films, Miniseries & Cinemax.”
