NASA gives Earth the all-clear for the next century, removing a particularly menacing asteroid, Apophis, from its “risk list”.

On March 27, 2021 NASA’s Perseverance Rover unlocked Mars Helicopter Ingenuity (release system unlocked) and started deployment process. As for now, NASA’s rover prepares to get the Helicopter upright. Flight scheme is known. Before Ingenuity takes its first flight on Mars, it must be squarely in the middle of its airfield – a 33-by-33-foot (10-by-10-meter) patch of Martian real estate chosen for its flatness and lack of obstructions. Once the helicopter and rover teams confirm that Perseverance is situated exactly where they want it to be inside the airfield, the elaborate process to deploy the helicopter on the surface of Mars begins.

Physicists at the LHCb Collaboration at CERN have found particles not behaving the way they should according to the guiding theory of particle physics. Could it be evidence of a brand new physics?
Plastics are one of the world’s largest polluters, taking hundreds of years to degrade in nature. A research team, led by YSE professor Yuan Yao and Liangbing Hu from the University of Maryland, has created a high-quality bioplastic from wood byproducts that they hope can solve one of the world’s most pressing environmental issues.
Efforts to shift from petrochemical plastics to renewable and biodegradable plastics have proven tricky — the production process can require toxic chemicals and is expensive, and the mechanical strength and water stability is often insufficient. But researchers have made a breakthrough, using wood byproducts, that shows promise for producing more durable and sustainable bioplastics.
A study published in Nature Sustainability, co-authored by Yuan Yao, assistant professor of industrial ecology and sustainable systems at Yale School of the Environment (YSE), outlines the process of deconstructing the porous matrix of natural wood into a slurry. The researchers say the resulting material shows a high mechanical strength, stability when holding liquids, and UV-light resistance. It can also be recycled or safely biodegraded in the natural environment, and has a lower life-cycle environmental impact when compared with petroleum-based plastics and other biodegradable plastics.

A new Covid-19 variant from the Amazon is now responsible for the majority of new infections in Brazil, with many doctors there saying they are seeing more young and otherwise healthy patients falling ill. Hopefully Covid doesnt bounce back and turn into the 1918 flu.
“We’re in the trenches here, fighting a war,” said Andréia Cruz, a 42-year-old emergency-ward nurse in the southern Brazilian city of Porto Alegre. In the past three weeks alone, the surrounding state of Rio Grande do Sul has seen nearly 5000 people die from Covid-19, more than in the final three months of last year.
The spread of the virus in Brazil threatens to turn this country of 213 million into a global public-health hazard. The so-called P.1 strain, present in more than 20 countries and identified in New York last week, is up to 2.2 times more contagious and as much as 61% more able to reinfect people than previous versions of the coronavirus, according to a recent study.
The P.1 is now responsible for the majority of new infections in Brazil, with many doctors here saying they are seeing more young and otherwise healthy patients falling ill. About 30% of people dying from Covid-19 are now under 60, compared with an average of about 26% during Brazil’s previous peak between June and August, according to official figures analyzed by The Wall Street Journal.
