Virgin Orbit, the sister company of Virgin Galactic, is gearing up for its next space launch in June when it will put six satellites in orbit.

The mission, named “Tubular Bells, Part One” after the first album Virgin Records released in 1973, will launch satellites for the U.S. Department of Defense, Poland’s SatRevolution and the Royal Netherlands Air Force.

Using “Almost Inconceivably Fast” Measurements, Researchers Find Bubbles Speed Up Energy Transfer

Posted by in category: particle physics

Findings that could help further understand how living tissue reacts to radiation exposure.

Energy flows through a system of atoms or molecules by a series of processes such as transfers, emissions, or decay. You can visualize some of these details like passing a ball (the energy) to someone else (another particle), except the pass happens quicker than the blink of an eye, so fast that the details about the exchange are not well understood. Imagine the same exchange happening in a busy room, with others bumping into you and generally complicating and slowing the pass. Then, imagine how much faster the exchange would be if everyone stepped back and created a safe bubble for the pass to happen unhindered.

An international collaboration of scientists, including UConn Professor of Physics Nora Berrah and post-doctoral researcher and lead author Aaron LaForge, witnessed this bubble-mediated enhancement between two helium atoms using ultrafast lasers. Their results are now published in Physical Review X.

Microwave Processing Isolates Red Ginseng Compounds That Suppress Lung Cancer Metastasis

Posted by in categories: biotech/medical, food

Most deaths associated with lung cancer are due to the migration of cancer cells to other organs—a process called metastasis. Although cancer therapies have advanced, treatments for lung cancer metastasis continue to lag.

The root of red ginseng (Panax ginseng) has been used as food and herbal medicine for thousands of years globally and especially in Korea and China, owing to its medicinal properties. However, the composition and activities of red ginseng vary depending on the processing method. Recent studies have shown the efficacy of red ginseng against lung cancer metastasis.

A new study conducted by scientists at the Korea Institute of Science and Technology (KIST) reports the successful use of a microwave processing method for ginseng that increases trace amounts of Rk1 and Rg5 ginsenosides—a class of natural steroid sugars found almost exclusively in plants of the genus Panax —that effectively inhibit the metastasis of lung cancer.

Largest autism genetics analysis to date uncovers more high-confidence candidates

Posted by in categories: biotech/medical, computing, genetics, neuroscience

After doubling its sample size, the largest study of genetic data from autistic people has identified 255 genes associated with the condition, an increase of more than 40 genes since the researchers’ 2019 update; 71 of the genes rise above a stringent statistical bar the team had not previously used. The new analysis also adds data from people with developmental delay or schizophrenia and considers multiple types of mutations.

“It’s a really significant step forward in what we do,” said Kyle Satterstrom, a computational biologist in Mark Daly’s lab at the Broad Institute in Cambridge, Massachusetts. Satterstrom presented the findings virtually on Tuesday at the 2021 International Society for Autism Research annual meeting. (Links to abstracts may work only for registered conference attendees.)

The team’s previous analyses used data from the Autism Sequencing Consortium, which enrolls families through their doctors. The researchers mainly scoured the genetic data to find rare, non-inherited mutations linked to autism.

Have scientists found the key to beating prostate cancer?

Posted by in category: biotech/medical

Researcher Professor Johann de Bono said: ‘There’s a lot of evidence that prostate cancer causes what we call immune tolerance — that the cancer suppresses the body from attacking it with its immune cells.


Scientists have discovered that a key protein may be the secret to treating prostate cancer patients with ‘miracle’ immunotherapy drugs.

Clinical trials have now begun – with the goal of unleashing cancer-killing white blood cells to attack the tumour.

On May 6, 2021 NASA published 4K UHD image from Ingenuity Mars Helicopter’s onboard camera and video footage during flight at Airfield B. Successful 4th flight on Mars for 133 meters distance by Ingenuity happened on April 30. New Ingenuity’s location called Airfield B. Previous location is Wright Brothers Field. The helicopter climbing to an altitude of 16 feet (5 meters) before flying south approximately 436 feet (133 meters) and then back, for an 872-foot (266-meter) round trip. In total, we were in the air for 117 seconds. NASA’s Ingenuity Mars Helicopter’s fourth flight path is superimposed here atop terrain imaged by the HiRISE camera aboard the agency’s Mars Reconnaissance Orbiter. NASA’s Ingenuity Mars Helicopter took 4K color image during its fourth flight. “Airfield B,” its new landing site, can be seen below. The helicopter will seek to set down there on its fifth flight attempt to 10 meters altitude on May 7th.

Self-generating yarn made from graphene oxide strands

Posted by in categories: biological, physics

A team of researchers from Zhejiang University, Xi’an Jiaotong University and Monash University has developed a way to bind multiple strands of graphene oxide into a thick cable. In their paper published in the journal Science, the group describes their process and possible uses for it. Rodolfo Cruz-Silva and Ana Laura Elías with Shinshu University and Binghamton University have published a Perspectives piece in the same issue outlining the work by the researchers and explaining why they believe the technique could prove useful in manufacturing efforts.

In recent years, have been exploring the possibility of making products using total or partial self-assembly as a way to produce them faster or at less cost. In where two materials self-assemble into a third material, scientists describe this as a fusion process, borrowing terminology from physics. So when a single material spontaneously separates into two or more other materials, they refer to it as a fission process. In this new effort, the researchers have developed a technique for creating graphene-oxide-based yarn that exploits both processes.

The work by the team is very basic. They created multiple strands of graphene oxide and then dunked them into a solvent for 10 minutes. When the strands were pulled from the solution, they banded together forming a cord, or single strand of yarn. They also developed a means for reversing the process—dunking the strand of yarn in a different solvent solution.
