A new machine-learning framework uses reported test results and death rates to calculate estimates of the actual number of current COVID-19 infections within all 50 U.S. states and 50 countries. Jungsik Noh and Gaudenz Danuser of the University of Texas Southwestern Medical Center present these findings in the open-access journal PLOS ONE on February 8,

We think government lockdowns cause substantial collateral health damage. For example, hospital admissions in the USA for emergency treatment of acute ischaemic strokes have been substantially lower in February-March, 2020, than in February-March, 2019, resulting in delayed treatment.1 Compared with a historical baseline, UK nursing homes and hospices saw an increase in the number of deaths between February and June, 2020, associated with acute coronary syndrome (a 41% increase), stroke (a 39% increase), and heart failure (a 25% increase).2

Emissions of puzzling compounds continue to rise, apparently from factories in East Asia.

"Risk of eternal lockdown. Hard questions need to be asked.. It's essential that we don't enter a semi-permanent state of emergency laws & basic rights switched on/off by the govt at will and without democratic scrutiny.. We cannot be locked down forever."

Normally, causal influence is assumed to go only one way-from cause to effect-and never back from the effect to the cause-the ringing of a bell does not cause the pressing of the button that triggered it. Now, researchers from the University of Oxford and the Université libre de Bruxelles have developed a theory of causality in quantum theory, according to which cause-effect relations can sometimes form cycles. This theory offers a novel understanding of exotic processes in which events do not have a definite causal order. The study has been published in Nature Communications.

Deforestation has converted swaths of land in the southern Amazon region from rainforest to farmland. The uses of the deforested land are diverse, and activities can range from small-scale farming in rural settlements to large-scale commodity agriculture. Commercial farms in the Southern Amazon can reach hundreds of thousands of hectares in area, exporting millions of tons in grains and beef every year.

Glaciers are not only melting, but also collapsing in the Third Pole region. In 2016, two glaciers in the western Third Pole's Aru Mountains collapsed, one after another. The first collapse caused nine human casualties and the loss of hundreds of livestock. However, that may not be the end of the catastrophe.

Now, a team of researchers at Osaka University has used flake-shaped Si nanopowder wrapped by ultrathin graphite sheets (GSs) to fabricate LIB electrodes with high areal capacity and current density. Generally treated as industrial waste, Si swarf is generated at a rate of 100,000 tons per year globally from Si ingots that are produced from silica through processes at 1000~1800°C. Water-based coolants and fixed abrasive grain wire saws are paving the way to the use of Si swarf as an anode active material with a high capacity at a reduced cost.

Noise limits the performance of modern quantum technologies. However, particles traveling in a superposition of paths can bypass noise in communication. A collaboration between the Universities of Hong-Kong, Grenoble and Vienna, as well as the Austrian Academy of Sciences, under the lead of Philip Walther, reveals novel techniques to reduce noise in quantum communication. The results, published in the latest issue of Physical Review Research, demonstrate that quantum particles traveling in a superposition of paths enable noise reduction in communications.

Atmospheric rivers are narrow corridors of concentrated moisture in the atmosphere. On average there are only three to five atmospheric rivers present in each hemisphere, covering just 10 percent of the globe's mid-latitude circumference but accounting for 90 percent of moisture transport in the same region.

The problem for consumers up to now has been that the negotiated prices were unknown, or impractical to raise in court due to evidentiary rules. The general rule is that witnesses must testify to facts within their personal knowledge. Notably, if a consumer contests a medical debt collection lawsuit, someone from the hospital must testify that the price charged is reasonable and customary-an assertion that, with regard to chargemasters, involves shading the truth and is vulnerable to cross-examination.

Their research findings have important implications for soil fertility, and by extension, crop health and yield, explained Laura Kaminsky, a doctoral candidate in plant pathology, who led the investigation under the guidance of Terrence Bell, assistant professor of phytobiomes.

In December, Antarctica lost its status as the last continent free of COVID-19 when 36 people at the Chilean Bernardo O'Higgins research station tested positive. The station's isolation from other bases and fewer researchers in the continent means the outbreak is now likely contained.
