SpaceX’s newest prototype of its Starship Mars-colonizing vehicle just passed a crucial pressure test, potentially paving the way for more ambitious trials in the near future.
Starship version SN2 survived a cryogenic pressure test late Sunday (March 8) at SpaceX’s South Texas facilities, company founder and CEO Elon Musk said. You can see a video timelapse of the test from Starship watcher Mary BocaChicaGal here for NASASpaceflight.com.

While it’s important to keep the wings of aircraft ice-free, the application of chemical deicers before takeoff can be problematic. German scientists are working on something that could help, in the form of an ice-repelling laser-based treatment for flight surfaces.
As many people will know from firsthand experience, waiting for an airliner to be sprayed with copious amounts of deicer is a hassle, potentially delaying takeoff. What’s more, the chemicals used can be quite expensive, plus they’re typically not very eco-friendly.
In order to allow smaller amounts of deicer to do the same job, some aircraft now incorporate heating elements in key areas of their fuselage, or they use setups that divert hot air from their engines to those same areas. The new system is intended to further minimize the need for deicers, perhaps even making them completely unnecessary.
If drone delivery companies get to shape city streets to their liking, the curbside array of lamp posts, garbage cans and free magazine distribution boxes will be joined someday by docking stations for their aircraft. Matternet on Tuesday unveiled a 10-foot tall kiosk three years in the making that’s designed to safely integrate its medical delivery drones into urban environments — and to drastically reduce the number of employees the startup needs and achieve a breakthrough on costs.
Plenty of companies have developed docking stations for recharging drones and to shelter them when they’re idle. Matternet could be the first to field a system that automatically handles cargo.
After its M2 drone enters through the top and docks, the station loads and unloads payload boxes, swap batteries and assesses the condition of the drone. Medical workers will be able to retrieve and drop off boxes through a hatch after scanning their IDs.
In order to understand what another person thinks and how he or she will behave, people must adopt someone else’s perspective. This ability is referred to as “theory of mind.” Until recently, researchers were at odds concerning the age at which children are able to do such perspective-taking. Scientists at the Max Planck Institute for Human Cognitive and Brain Sciences (MPI CBS), University College London, and the Social Neuroscience Lab Berlin shed new light on this question in a study now published in the Proceedings of the National Academy of Sciences.
According to the study, four-year-olds seem to be able to understand what others think. The study reports that this unique ability emerges around four years of age because of the maturation of a specific brain network that enables this. Younger children are capable of predicting others’ behavior based on what they think, but the study shows that this prediction of behavior relies on a different brain network. The brain seems to have two separate systems to take another person’s perspective, and these mature at different rates.
The researchers investigated these relations in a sample of three- to four-year-old children with the help of a video clips that show a cat chasing a mouse. The cat watches the mouse hiding in one of two boxes. While the cat is away, the mouse sneaks over to the other box, unnoticed by the cat. Thus, when the cat returns, it should still believe that the mouse is in the first location.
BERLIN (AP) — Germany has confirmed more than 1,100 cases of the new coronavirus but — so far — just two deaths, far fewer than other European countries with a similar number of reported infections.
Experts said Monday that rapid testing as the outbreak unfolded meant Germany has probably diagnosed a much larger proportion of those who have been infected, including younger patients who are less likely to develop serious complications.
That’s given authorities more chance of containing the virus, and more time to prepare for it.
The two tech titans funded an effort to bring metagenomic sequencing and software to poor countries. Now, it’s helping trace the spread of the new coronavirus.
