A new sunshade, or visor, designed to reduce the brightness of SpaceX’s Starlink broadband Internet satellites will debut on the company’s next launch, a measure intended to alleviate astronomers’ concerns about impacts on observations through ground-based telescopes, SpaceX founder Elon Musk said.

Beginning with the next launch of Starlink satellites — scheduled for 18 May from Cape Canaveral — SpaceX will try out a new light-blocking panel to make the spacecraft less visible to skywatchers and astronomers.

“We have a radio-transparent foam that will deploy nearly upon the satellite being released (from the rocket),” Musk said on 27 April at a virtual meeting of the National Academies’ Decadal Survey on Astronomy and Astrophysics 2020 panel, a committee charged with setting the top priorities for US astronomy for the next decade.

Why hasn’t #MachineLearning conquered SARS-CoV-2 that causes COVID-19 (P.S., SARS-CoV-2 is the name of the #virus, while COVID-19 is the name of the disease)? One of the possible answers is that the virus “learns” faster than machines through “mutations”.

That causes us thinking: If mutation is such an efficient weapon (for virus), can we learn something from it and then apply our understanding to #DeepLearning to create “fast-mutating” #DeepLearning models capable of helping us to fight intractable crisis like a #pandemic?

Tom Cruise is going to film in space thanks to Elon Musk.

EXCLUSIVE: I’m hearing that Tom Cruise and Elon Musk’s Space X are working on a project with NASA that would be the first narrative feature film – an action adventure – to be shot in outer space. It’s not a Mission: Impossible film and no studio is in the mix at this stage but look for more news as I get it. But this is real, albeit in the early stages of liftoff.

Mission: Impossible Fallout took a break, literally when he broke his ankle in a leap from one rooftop to the other and he also hung from a helicopter; he hung from the side of a jet plane during takeoff in Mission: Impossible Rogue Nation, and in Mission: Impossible: Ghost Protocol he scaled the Burj Khalifa, the Dubai skyscraper, and executed stunts 123 floors up. He is meticulous in preparing these stunts he does, which are frightening just to watch.

SAN DIEGO, May 4, 2020 /PRNewswire/ — Global Institute of Stem Cell Therapy and Research (GIOSTAR), the worldwide leader in stem cell research, is pleased to announce that they have received an approval for a COVID-19 clinical trial, led by their Medical Director Dr. Prabhat Soni. GIOSTAR will conduct the trial using stem cells to treat COVID-19 patients, under the approval of the United States Food and Drug Administration (FDA) “expanded access for compassionate use” program. The Institute is exploring a promising alternative approach to the devastating disorder, which leverages the anti-inflammatory properties of mesenchymal stem cells (MSCs). According to Dr. Soni, the investigation is based upon two decades of stem cell research by GIOSTAR Co-Founder, Chairman and Chief Scientific Officer Dr. Anand Srivastava.

Rhesus macaques don’t monkey around when it comes to HIV; they have a protein that effectively disables invading HIV particles.

A group of University of Chicago scientists announced an innovative study that explains how the macaques’ immune protein, called TRIM5α, works its magic. It also represents a significant step forward in the science of modeling how complex biological proteins assemble themselves, the scientists said.

“These proteins work together to encase the HIV capsid in a hexagonal net and restrict viral activity,” said postdoctoral fellow Alvin Yu and lead author of the study, which was published in Nature Communications.

In the summer of 2010, I had the opportunity to be part of the team that designed and built the first passive freezer that we’d ever heard of. The idea was simple, we create a well-insulated room and stack several thousand 2-liter bottles full of salt water along the walls. In the winter, we open hatches in the ceiling and everything freezes. At the end of the winter, we close the hatches and it stays at about 25°F for the whole year.

The team of students, led by physics teacher Tom Tailer ran some calculations to make sure the physics added up and calculated that we needed about 3000 bottles and about 18 inches of foam insulation on the walls and ceiling for good performance. We built the structure and insulated it using waste styrofoam, ground-up using a modified leaf shredder.

Scaling Up

There’s a long way to go between a proof-of-concept prototype and installing an engine in a real plane. But the prototype was able to launch a one-kilogram steel ball 24 millimeters into the air. That’s the same thrust, proportional to scale, as a conventional jet engine.

“Our results demonstrated that such a jet engine based on microwave air plasma can be a potentially viable alternative to the conventional fossil fuel jet engine,” lead researcher and Wuhan University engineer Jau Tang said in a press release.
