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 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.

Too bad.

Nearly 500 pages of evidence were made public during the House Judiciary’s marathon hearing this week on potential anti-competitive actions by Amazon, Facebook, Google and Apple. We’ve collected them here with added context and an omnibus, searchable version for anyone who’d rather not juggle four dozen documents.

The emails, chat logs and other communications listed here trickled out online as the hearings went on. Many are internal documents that were never meant to be exposed publicly — for instance, Facebook CEO Mark Zuckerberg telling a colleague that “we can likely always just buy any competitive startups” shortly before acquiring Instagram in 2012.

The Hackett Group at EMBL Rome explores epigenetics, genome regulation and cell identity. Recently, the scientists developed a novel CRISPR molecular tool for editing the epigenome, enabling transient modifications that can switch certain genes “on” and “off” temporarily.

The SARS-CoV-2 virus that has caused the COVID-19 global pandemic makes its way into a host cell via a protein known as ACE2, which is involved in a range of physiological functions in the body.

What happens when you transiently turn “off” the gene that encodes this protein? Can SARS-CoV-2 still enter the cell and cause infection? This is what Hackett and colleagues are currently exploring in animal models, to determine whether epigenetic silencing could be a treatment approach for COVID-19 in humans.

DeepMind this week released Acme, a framework intended to simplify the development of reinforcement learning algorithms by enabling AI-driven agents to run at various scales of execution. According to the engineers and researchers behind Acme, who coauthored a technical paper on the work, it can be used to create agents with greater parallelization than in previous approaches.

Reinforcement learning involves agents that interact with an environment to generate their own training data, and it’s led to breakthroughs in fields from video games and robotics to self-driving robo-taxis. Recent advances are partly attributable to increases in the amount of training data used, which has motivated the design of systems where agents interact with instances of an environment to quickly accumulate experience. This scaling from single-process prototypes of algorithms to distributed systems often requires a reimplementation of the agents in question, DeepMind asserts, which is where the Acme framework comes in.
