Whenever I tell my friends about the potential of Quantum Computing, for example, how a Quantum Computer (QC) can do a large number of calculations in parallel worlds, they look at me like I’m kind of crazy.
“At first, we thought it was absurd. How else could you respond to the idea that black holes generate swirling clouds of planet-sized particles that could be the dark matter thought to hold galaxies together? We tend to think about particles as being tiny but, theoretically, there is no reason they can’t be as big as a galaxy,” said theoretical physicist Asimina Arvanitaki, at the Perimeter Institute for Theoretical Physics referring to the heated debate about the standard model for dark matter that proposes that it is ‘cold,’ meaning that the particles move slowly compared to the speed of light which is tied to the mass of dark matter particles. The lower the mass of the particle, the ‘warmer’ it is and the faster it will move.
On January 9, NASA physicists using the Hubble Space Telescope reported that although the type of particle that makes up dark matter is still a mystery, a compelling observational test for the cold dark matter passed “with flying colors,” The NASA team used a new “cosmic magnifying glasses” technique that found that dark matter forms much smaller clumps than previously known, confirming one of the fundamental predictions of the widely accepted “cold dark matter” theory.
Physicists at the University of California, Davis, taking the temperature of dark matter, the mysterious substance that makes up about a quarter of our universe now report that the model of cold (more massive) dark matter holds at very large scales” said Chris Fassnacht, a physics professor at UC Davis, “but doesn’t work so well on the scale of individual galaxies.” That’s led to other models including ‘warm’ dark matter with lighter, faster-moving particles and ‘hot’ dark matter with particles moving close to the speed of light that have been ruled out by observations.
A team of engineers at the University of California San Diego have built a squid robot that can propel itself through the water untethered, just like the real thing.
“Essentially, we recreated all the key features that squids use for high-speed swimming,” Michael T. Tolley, co-author of the paper published in the journal Bioinspiration and Biomimetics last month.

Vaccines could take years, and preventative drugs could help bridge the gap.
Though many people are pinning their hopes on a COVID-19 vaccine, another option is available: preventive treatment. At a Senate hearing this week, Anthony Fauci noted that a vaccine — which is probably months or years away — isn’t the only way to protect someone from a life-threatening virus.
These treatments could protect people against infection for a few weeks or months, said Fauci, the director of the National Institute of Allergy and Infectious Diseases. While most ongoing research studies are focused on finding treatments for people who are already sick with COVID-19, some researchers are looking to see if they can stop people who are at high risk from getting sick in the first place.

When you need to tell the future how cool you were, data longevity is key. A team of researches might have created a data storage medium for the ages with tungsten and silicon nitride.
The discovery is being used to make a drug for potential therapeutic and preventive use against COVID-19.
In this brief, at times controversial— even radical—volume. Dr. Ian C. Hale guides us through likely scenarios and gives us life-saving recommendations for effectively dealing with the next waves of the COVID-19 pandemic. This is a must read for public policy makers, medical professionals, and those mapping out their financial future in the post-corona world.
SpaceX launched 60 Starlink satellites atop a Falcon 9 rocket from Pad 39A at NASA’s Kennedy Space Center in Florida on Oct. 6, 2020. The private spaceflight company has now launched well over 700 of these internet-providing satellites into orbit.
