The main route of transmission of SARS CoV infection is presumed to be respiratory droplets. However the virus is also detectable in other body fluids and excreta. The stability of the virus at different temperatures and relative humidity on smooth surfaces were studied. The dried virus on smooth surfaces retained its viability for over 5 days at temperatures of 22–25°C and relative humidity of 40–50%, that is, typical air-conditioned environments. However, virus viability was rapidly lost (3 log₁₀) at higher temperatures and higher relative humidity (e.g., 38°C, and relative humidity of 95%). The better stability of SARS coronavirus at low temperature and low humidity environment may facilitate its transmission in community in subtropical area (such as Hong Kong) during the spring and in air-conditioned environments. It may also explain why some Asian countries in tropical area (such as Malaysia, Indonesia or Thailand) with high temperature and high relative humidity environment did not have major community outbreaks of SARS.

Severe acute respiratory syndrome (SARS), was a new emerging disease associated with severe pneumonia and spread to involve over 30 countries in 5 continents in 2003. A novel coronavirus was identified as its cause [1–3]. SARS had a dramatic impact on health care services and economies of affected countries, and the overall mortality rate was estimated to be 9%, but rising to 50% in those aged 60 or above [4]. A notable feature of this disease was its predilection for transmission in the health care setting and to close family and social contacts. The disease is presumed to be spread by droplets, close direct or indirect contact, but the relative importance of these routes of transmission is presently unclear. A study showed that viral aerosol generation by a patient with SARS was possible and therefore airborne droplet transmission was a possible means of transmission [5].

The Tesla Model S and Model X come standard with Bioweapon Defense Mode, which is possible due to a massive HEPA filter. If you haven’t seen it or replaced it, you’re likely to be shocked by its size. According to Tesla, the filter is “100 times more effective than premium automotive filters.” It removes “at least 99.97% of fine particulate matter and gaseous pollutants, as well as bacteria, viruses, pollen, and mold spores.” Is it really necessary, though?

There’s a pretty good chance that going out in your car is not going to make you highly susceptible to contracting the coronavirus, but we’re not doctors. At this point, it seems even doctors and scientists aren’t 100-percent sure about many details related to this new disease. We can tell you that we have seen many people walking alone outside with masks and gloves on, and just about as many people driving down the road with their windows closed and masks and gloves on.

WTI, the US benchmark, finished at -$37.63 a barrel on Monday. Producers are paying stockpilers to take barrels off their hands, as the coronavirus crisis saps demand and producers run out of places to store excess crude.

👽 Stalin’s Crab is eating the Oceans biodiversity and tis gaining terrain as we are speaking now.

They’re multiplying in the Barents Sea. And they’re heading West. Meet the red king crabs. 🦀.

Salamanders and lizards can regrow limbs. Certain worms and other creatures can generate just about any lost part — including a head — and the latest genetics research on body part regeneration is encouraging.

Since they are adult stem cells that have reverted back to a less developed — more pluripotent — state, iPSCs remind scientists of the stem cells that enable lizards to regrow limbs, and zebrafish to regrow hearts. When it comes to limbs, the understanding the regrowth process could help scientists promote nerve regeneration in cases when a limb is severely damaged, but not physically lost. Nerves of the human peripheral nervous system do have the ability to regrow, but whether this actually happens depends on the extent of the injury, so understanding the stem cell physiology in zebrafish and other animals could help clinicians fill the gap. The knowledge gained also could impact development of treatments aimed at promoting nerve regrowth in the central nervous system, for instance in the spinal cord after an injury.

Your phone’s GPS, the Wi-Fi in your house and communications on aircraft are all powered by radio-frequency, or RF, waves, which carry information from a transmitter at one point to a sensor at another. The sensors interpret this information in different ways. For example, a GPS sensor uses the angle at which it receives an RF wave to determine its own relative location. The more precisely it can measure the angle, the more accurately it can determine location.

In a new paper published in Physical Review Letters, University of Arizona engineering and optical sciences researchers, in collaboration with engineers from General Dynamics Mission Systems, demonstrate how a combination of two techniques—radio frequency photonics sensing and quantum metrology—can give sensor networks a previously unheard-of level of precision. The work involves transferring information from electrons to photons, then using quantum entanglement to increase the photons’ sensing capabilities.

“This quantum sensing paradigm could create opportunities to improve GPS systems, astronomy laboratories and biomedical imaging capabilities,” said Zheshen Zhang, assistant professor of materials science and engineering and optical sciences, and principal investigator of the university’s Quantum Information and Materials Group. “It could be used to improve the performance of any application that requires a network of sensors.”

Compared to a conventional computer, this device has a learning capability that is not software-based.

The star itself is about the same mass and a little larger than the Sun — a minority in our exoplanet hunts. It’s orbited by six planets: a super-Earth and five mini-Neptunes.

After monitoring it for seven years, astronomers have discovered that all six of those planets are orbiting HD 158259 in almost perfect orbital resonance. This discovery could help us to better understand the mechanisms of planetary system formation, and how they end up in the configurations we see.
