The prestigious news outlet mapped the performance of 30 leading economies by plotting their public health and economic outcomes and grouping them based on whether they have instituted light, moderate or severe restrictions on commerce and social interactions.

The matrix included countries and territories’ economic outcomes, including the benchmarks of GDP, unemployment and fiscal stimulus packages and health outcomes based on testing, infection and death statistics provided by health ministries and government authorities and graphed by Worldometer and Johns Hopkins University.

As seen in the ranking chart, Vietnam stands at the furthest end with “better public health outcome,” with Taiwan coming close, followed by New Zealand, South Korea, Iceland, Argentina and Australia.

Researchers led by biologists at Tufts University have discovered that the brains of developing frog embryos damaged by nicotine exposure can be repaired by treatment with certain drugs called “ionoceuticals” that drive the recovery of bioelectric patterns in the embryo, followed by repair of normal anatomy, gene expression and brain function in the growing tadpole. The research, published today in Frontiers in Neuroscience, introduces intervention strategies based on restoring the bioelectric “blueprint” for embryonic development, which the researchers suggest could provide a roadmap for the exploration of therapeutic drugs to help repair birth defects.

Space is getting crowded. Aging satellites and space debris crowd low-Earth orbit, and launching new satellites adds to the collision risk. The most effective way to solve the space junk problem, according to a new study, is not to capture debris or deorbit old satellites: it’s an international agreement to charge operators “orbital-use fees” for every satellite put into orbit.

China’s space program will launch a Mars mission in July, according to its current plans. This will include deploying an orbital probe to study the red planet, and a robotic, remotely-controlled rover for surface exploration. The U.S. has also been planning another robotic rover mission for Mars, and it’s set to take off this summer, too – peak time for an optimal transit from Earth to Mars thanks to their relative orbits around the Sun.

This will be the first rover mission to Mars for China’s space program, and is one of the many ways that it’s aiming to better compete with NASA’s space exploration efforts. NASA has flown four previous Mars rover missions, and its fifth, with an updated rover called ‘Perseverance,’ is set to take place this years with a goal of making a rendezvous with Mars sometime in February 2021.

NASA’s mission also includes an ambitious rock sample return plan, which will include the first powered spacecraft launch from the red planet to bring that back. The U.S. space agency is also sending the first atmospheric aerial vehicle to Mars on this mission, a helicopter drone that will be used for short flights to collect additional data from above the planet’s surface.

Our #LaunchAmerica mission passed its final major review today at NASA’s Space Launch System in Florida, and teams received the “go” to proceed toward launch. NASA Astronauts Robert Behnken and Douglas Hurley are scheduled to liftoff aboard the SpaceX Falcon 9 rocket and Crew Dragon spacecraft Wednesday at 4:33 p.m. EDT: https://go.nasa.gov/2ATRHSq
