The JL-3, which could reach the United States if launched from the Chinese coast, is expected to be used to arm Type 096 submarines.

The U.S. space agency National Aeronautics Space Administration (NASA), European Space Agency (ESA), and Japan Aerospace Exploration Agency (JAXA) are inviting coders, entrepreneurs, scientists, designers, storytellers, makers, builders, artists, and technologists to participate in a virtual hackathon May 30–31 dedicated to putting open data to work in developing solutions to issues related to the COVID-19 pandemic.
During the global Space Apps COVID-19 Challenge, participants from around the world will create virtual teams that – during a 48-hour period – will use Earth observation data to propose solutions to COVID-19-related challenges ranging from studying the coronavirus that causes COVID-19 and its spread to the impact the disease is having on the Earth system. Registration for this challenge opens in mid-May.
“There’s a tremendous need for our collective ingenuity right now,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate. “I can’t imagine a more worthy focus than COVID-19 on which to direct the energy and enthusiasm from around the world with the Space Apps Challenge that always generates such amazing solutions.”
The unique capabilities of NASA and its partner space agencies in the areas of science and technology enable them to lend a hand during this global crisis. Since the start of the global outbreak, Earth science specialists from each agency have been exploring ways to use unique Earth observation data to aid understanding of the interplay of the Earth system – on global to local scales – with aspects of the COVID-19 outbreak, including, potentially, our ability to combat it. The hackathon will also examine the human and economic response to the virus.

“Nanotechnology offers unprecedented possibilities for progress—defeating poverty, starvation, and disease, opening up outer space, and expanding human capacities. But it also brings unprecedented risks—the specter of devastating wars fought with far more powerful weapons of mass destruction.” — Chris Phoenix, Director of Research, Center for Responsible Nanotechnology.

A Personal View of Systems Biology and the Coming of “Big” Science.
This is a truly remarkable time in the biological sciences. Biology now has the opportunity to effectively attack some of the most fundamental problems of society, including healthcare, agriculture, bio-energy, a sustainable environment, and nutrition.
MANILA, Philippines — A dengue case forecasting system using space data made by Philippine developers won the 2019 National Aeronautics and Space Administration’s International Space Apps Challenge. Over 29,000 participating globally in 71 countries, this solution made it as one of the six winners in the best use of data, the solution that best makes space data accessible, or leverages it to a unique application.
Dengue fever is a viral, infectious tropical disease spread primarily by Aedes aegypti female mosquitoes. With 271,480 cases resulting in 1,107 deaths reported from January 1 to August 31, 2019 by the World Health Organization, Dominic Vincent D. Ligot, Mark Toledo, Frances Claire Tayco, and Jansen Dumaliang Lopez from CirroLytix developed a forecasting model of dengue cases using climate and digital data, and pinpointing possible hotspots from satellite data.
Correlating information from Sentinel-2 Copernicus and Landsat 8 satellites, climate data from the Philippine Atmospheric, Geophysical and Astronomical Services Administration of the Department of Science and Technology (DOST-PAGASA) and trends from Google search engines, potential dengue hotspots will be shown in a web interface.
Salamanders and lizards can regrow limbs. Certain worms and other creatures can generate just about any lost part — including a head — and the latest genetics research on body part regeneration is encouraging.
Since they are adult stem cells that have reverted back to a less developed — more pluripotent — state, iPSCs remind scientists of the stem cells that enable lizards to regrow limbs, and zebrafish to regrow hearts. When it comes to limbs, the understanding the regrowth process could help scientists promote nerve regeneration in cases when a limb is severely damaged, but not physically lost. Nerves of the human peripheral nervous system do have the ability to regrow, but whether this actually happens depends on the extent of the injury, so understanding the stem cell physiology in zebrafish and other animals could help clinicians fill the gap. The knowledge gained also could impact development of treatments aimed at promoting nerve regrowth in the central nervous system, for instance in the spinal cord after an injury.
Caveats
Even where regeneration is natural for humans, numerous regeneration cycles can put a person at greater risk of cancer. In the liver, for instance, disease can result in liver cancer largely because the organ produces new cells to replace the damaged ones. This is what happens in cirrhosis and after certain viral conditions when there are periods when regeneration overtakes liver deterioration. Prometheus avoided this fate, but we don’t know how well the process would work in humans, if a regenerative system based on iPSCs or some other types of stem cell is used clinically on a large scale. Regenerative medicine is promising and exciting to hear about. But we are at a very early stage, and reports on limb regrowth should be taken with caution.
Computer scientists established a new boundary on computationally verifiable knowledge. In doing so, they solved major open problems in quantum mechanics and pure mathematics.
