The interstellar visitor ‘Oumuamua, discovered in 2017, may represent an entirely new type of astrophysical object, two astronomers say.
February 27, 2020 — Accuray Incorporated announced that Mercy Hospital St. Louis continues to demonstrate its commitment to improving patient outcomes with the installation of the first CyberKnife M6 System in Missouri at their state-of-the-art David C. Pratt Cancer Center. The next-generation CyberKnife System has been shown to deliver precise stereotactic radiosurgery (SRS) and stereotactic body radiation therapy (SBRT) treatments with ease, making it possible for the clinical team to expand access to one of the most advanced methods for administering radiation to more cancer patients.
SRS and SBRT are non-invasive forms of radiation therapy that use high doses of very targeted radiation to destroy tumors, in just a few treatment sessions (1 to 5). SRS is commonly used to treat conditions within the brain and spine, while SBRT is used for those tumors located outside these areas. The CyberKnife M6 System is equipped with sophisticated functionality that will streamline the creation of personalized treatment plans and reduce the time to deliver radiation treatments, enabling the Mercy St. Louis team to offer precision SRS and SBRT treatments to more patients each day.
The Mercy Hospital St. Louis team uses the most advanced radiotherapy technology to design and deliver an individualized treatment plan designed to help cancer patients take control of their disease and resume their lives. The hospital is part of the Mercy system, named one of the top five large U.S. health systems from 2016 to 2019 by IBM Watson Health. Mercy announced in 2018 that it intended to work with Accuray to enhance cancer care through advanced life-saving technology, including the CyberKnife System that was recently installed as well as Accuray Radixact Systems that will be installed at other Mercy hospitals.
Munich-based residential vanadium redox flow battery start-up VoltStorage has secured another $7 million from investors including the Bayern Kapital subsidiary of the development bank of Bavaria; family investment house Korys; the EU-backed EIT Innoenergy, New Jersey-based venture capital fund and seed investor SOSV and Zurich power company Energie 360.
The firm claims its flow battery system can complete more than 10,000 charge cycles without any effect on capacity and says its electrolyte is a recyclable, non-flammable vanadium solution. VoltStorage’s modular unit reportedly offers a continuous power rating of 1.5 kW and nominal energy of 6.2 kWh. The unit comes with a ten-year warranty.
More than 20 flow battery chemistries, including zinc-bromine, zinc-iron, zinc-cerium and magnesium-vanadium have been studied with vanadium redox the closest to wide commercialization. Vanadium, the dominant cost in the electrolyte, is a metal mined in Russia, China and South Africa although there are reserves in the U.S. and Canada. It is used predominantly as a steel additive. Flow battery manufacturers include Washington-based UET, Montana’s Vizn, California-based Primus, Japan’s Sumitomo, Anglo-Canadian Invinity Energy Systems – formed after the recent merger of California’s Avalon and U.K.-based redT – and Form Energy.
A report from Google’s Project Zero also looks at 2019 zero-day statistics and draws some interesting conclusions.
A study from researchers at KAIST (Korea Advanced Institute of Science and Technology) is providing new insights into a cellular energy pathway that has been linked to longer lifespan. The research, conducted in human cells and roundworms, raises the prospect of anti-aging therapeutics that can extend lifespan by activating this pathway.
AMPK (adenosine monophosphate-activated protein kinase) is an enzyme that acts as a metabolic master switch. It has been described as a “magic bullet” protein, conferring broad beneficial health effects, from improving cardiovascular health to extending lifespan. It is activated in response to low cellular energy levels, as is often seen during exercise or periods of caloric restriction.
An increasing volume of study has found activating AMPK in animal models leads to notable increases in lifespan, prompting a surge in research investigating this enzyme.
SAN CARLOS, Calif., Feb. 19, 2020 /PRNewswire/ — ZAP Surgical Systems, Inc. today announced an agreement with Bonifatius Hospital in Lingen, Germany to acquire ZAP-X® stereotactic radiosurgery (SRS) technology.
SRS is a well-known and effective procedure for non-invasively treating select brain tumors and brain metastases. However, significant acquisition and radiation shielding costs of historical SRS systems have limited widespread access to this potentially life-saving therapy. Consequently, scarce availability of SRS treatment has remained heavily concentrated in large urban hospitals.
Nobody can shoot a bullet through a banana in such a way that the skin is perforated but the banana remains intact. However, on the level of individual atomic layers, researchers at TU Wien (Vienna) have now achieved such a feat—they developed a nano-structuring method with which certain layers of material can be perforated extremely precisely and others left completely untouched, even though the projectile penetrates all layers. This is made possible with the help of highly charged ions. They can be used to selectively process the surfaces of novel 2-D material systems, for example, to anchor certain metals on them, which can then serve as catalysts. The new method has now been published in the journal ACS Nano.
New materials from ultra-thin layers
Materials that are composed of several ultra-thin layers are regarded as an exciting new field of materials research. The high-performance material graphene, which consists of only a single layer of carbon atoms, has been used in many new thin-film materials with promising new properties.

Vacuum toilets are flush toilets that use suction for the removal of faeces and urine resulting in a minimal requirement of water (0.5 to 1.5 litres). Vacuum toilets provide the same level of comfort as traditional flush toilets and they help saving costs due to the minimised amount of flush water. Due to the fact that the effluent has a high organic matter content, vacuum toilets are specifically adapted for the use in combination with separate greywater and blackwater treatment; or aerobic digestion treatment for biogas production. Vacuum toilet systems are applicable both in large and small buildings, trains, ships and airplanes.
