CDC is closely monitoring an outbreak of respiratory illness caused by a novel (new) coronavirus (named “2019-nCoV”) that was first detected in Wuhan City, Hubei Province, China and which continues to expand. Chinese health officials have reported thousands of infections with 2019-nCoV in China, with the virus reportedly spreading from person-to-person in many parts of that country. Infections with 2019-nCoV, most of them associated with travel from Wuhan, also are being reported in a growing number of international locations, including the United States. The United States reported the first confirmed instance of person-to-person spread with this virus on January 30, 2020.
Coronaviruses are a large family of RNA viruses that are common in many different species of animals, including camels, cattle, cats, and bats. Rarely, animal coronaviruses can infect people and then spread between people such as with MERS and SARS.

Researchers at Columbia University and University of California, San Diego, have introduced a novel "multi-messenger" approach to quantum physics that signifies a technological leap in how scientists can explore quantum materials.
The findings appear in a recent article published in Nature Materials, led by A. S. McLeod, postdoctoral researcher, Columbia Nano Initiative, with co-authors Dmitri Basov and A. J. Millis at Columbia and R.A. Averitt at UC San Diego. "We have brought a technique from the inter-galactic scale down to the realm of the ultra-small," said Basov, Higgins Professor of Physics and Director of the Energy Frontier Research Center at Columbia. Equipped with multi-modal nanoscience tools we can now routinely go places no one thought would be possible as recently as five years ago."

One of the greatest unsolved puzzles in all of science is dark energy. The Universe isn’t just expanding, but the expansion rate that we infer for distant galaxies is accelerating: their recession velocity speeds up from our perspective as time goes on. This was a surprise when it was discovered empirically in the 1990s, and more than two decades later, we still don’t understand where this mysterious form of energy, the most abundant in all the Universe, comes from.
While you can explain dark energy in the context of General Relativity, it’s recently become fashionable to attempt to explain dark energy by modifying gravity instead. Recently, the award-winning theoretical work of Dr. Claudia de Rham has come into focus, leading The Guardian to ask, "Has physicist’s gravity theory solved ‘impossible’ dark energy riddle?" It’s a fascinating possibility, but one that demands an appropriate level of skepticism.

This year will see a relatively low number of icebergs drifting into busy shipping regions in the north-west Atlantic, according to a combination of control systems and artificial intelligence forecasting models developed by experts at the University of Sheffield.
A recently published control systems model has been used to predict that between 479 and 1,015 icebergs will reach waters south of 48°N—the area of greatest risk to shipping traveling between Europe and north-east North America—in 2020, compared with 1,515 observed there last year.
