Virus DNA left on a hospital bed rail was found in nearly half of all sites sampled across a ward within 10 hours and persisted for at least five days, according to a new study by UCL and Great Ormond Street Hospital (GOSH).

The study, published as a letter in the Journal of Hospital Infection, aimed to safely simulate how SARS-CoV-2, the virus that causes Covid-19, may spread across surfaces in a hospital.

Instead of using the SARS-CoV-2 virus, researchers artificially replicated a section of DNA from a plant-infecting virus, which cannot infect humans, and added it to a milliliter of water at a similar concentration to SARS-CoV-2 copies found in infected patients’ respiratory samples.

No one can say whether androids will dream of electric sheep, but they will almost certainly need periods of rest that offer benefits similar to those that sleep provides to living brains, according to new research from Los Alamos National Laboratory.

“We study spiking neural networks, which are systems that learn much as living brains do,” said Los Alamos National Laboratory computer scientist Yijing Watkins. “We were fascinated by the prospect of training a neuromorphic processor in a manner analogous to how humans and other biological systems learn from their environment during childhood development.”

Watkins and her research team found that the network simulations became unstable after continuous periods of unsupervised learning. When they exposed the networks to states that are analogous to the waves that living brains experience during sleep, stability was restored. “It was as though we were giving the neural networks the equivalent of a good night’s rest,” said Watkins.

Two NASA astronauts last Sunday entered the International Space Station (ISS) from SpaceX’s Dragon spacecraft after a historic launch from the Kennedy Space Center in Florida, marking the dawn of a new age in commercial space travel. The National Aeronautics and Space Administration (NASA), which is the agency for space research, aeronautics and related programmes in the US and the pre-eminent such agency of its kind, alongside the ESA, JAXA, China’s space agency and India’s ISRO, confirmed the arrival of astronauts Bob Behnken (49) and Doug Hurley (53) at the ISS.

A spaceship with only touch screen controls

One of the most fascinating aspects was that both the astronauts became the first astronauts launched to space on a privately-owned rocket and they also became the first to pilot a spaceship using only touchscreen controls. SpaceX’s Crew Dragon refrained from using the infamous maze of manual controls and switches found on retired spacecraft like the Space Shuttle or the Apollo command modules.

HAVANA HAVANA (Reuters) — Communist-run Cuba said this week that use of two drugs produced by its biotech industry that reduce hyper-inflammation in seriously ill COVID-19 patients has sharply curbed its coronavirus-related death toll.

Health authorities have reported just two virus-related deaths over the past nine days among more than 200 active cases on the Caribbean’s largest island, a sign they may have the worst of the outbreak under control.

The government, which hopes to increase its biopharmaceutical exports, has touted various drugs it produces for helping prevent infection with the new coronavirus and treating the COVID-19 disease it causes.

“Properties that have never been found in nature”

Norwegian scientist Birger Sørensen has claimed the novel coronavirus SARS-CoV-2 is not natural in origin. The claims by the co-author of the British-Norwegian study—published in the Quarterly Review of Biophysics —are supported by the former head of Britain’s MI6, Sir Richard Dearlove.

The study from Sørensen and British professor Angus Dalgleish show that the coronavirus’s spike protein contains sequences that appear to be artificially inserted.

If you are interested in mind uploading, then I have an excellent video for you to watch. Dr Keith Wiley discusses personal identity issues associated with whole brain emulation in today’s Carboncopies Journal Club Meeting.

The study is potentially applicable to humans and reflects a growing interest in new theories of consciousness that are experimentally testable.

Russian President Vladimir Putin of Russia declared a state of emergency in a region of northern Siberia after a huge oil spill last week turned a river crimson. It is threatening significant damage to the Arctic region. [ 317 more words ].

Norilsk Nickel is the world’s largest producer of platinum and nickel.

The company, along with the Russian Emergency Situations Ministry, dispatched hundreds of personnel to clean up the spill. So far, Norilsk Nickel said they had managed to gather up only around 340 tons of the oil.

Physicists have measured the flight times of electrons emitted from a specific atom in a molecule upon excitation with laser light. This has enabled them to measure the influence of the molecule itself on the kinetics of emission.

Photoemission — the release of electrons in response to excitation by light — is one of the most fundamental processes in the microcosm. The kinetic energy of the emitted electron is characteristic for the atom concerned, and depends on the wavelength of the light employed. But how long does the process take? And does it always take the same amount of time, irrespective of whether the electron is emitted from an individual atom or from an atom that is part of a molecule? An international team of researchers led by laser physicists in the Laboratory for Attosecond Physics (LAP) at LMU Munich and the Max Planck Institute of Quantum Optics (MPQ) in Garching has now probed the influence of the molecule on photoemission time.

The theoretical description of photoemission in 1905 by Albert Einstein marked a breakthrough in quantum physics, and the details of the process are of continuing interest in the world of science and beyond. How the motions of an elementary quantum particle such as the electron are affected within a molecular environment has a significant bearing on our understanding of the process of photoemission and the forces that hold molecules together.
