NASA Awards SpaceX $53 Million for Orbital Starship Refueling Test
Posted by Raphael Ramos in category: space travel
Refueling in orbit is a crucial step for SpaceX to allow its Starship spacecraft to make the journey to faraway places, including the Moon and Mars. The idea is to launch multiple Starships, some destined to top up others while in orbit.
“Combining Starship’s rapid reusability with orbital refilling is critical to economically transporting large numbers of crew and cargo to the Moon and Mars,” SpaceX wrote in a tweet celebrating the news.
NASA is contracting SpaceX to demonstrate the transfer of ten metric tons of liquid oxygen propellant between one Starship and another, a collaboration with NASA’s Glenn Research Center and the Marshall Space Flight Center.
This guy has spent eight years creating a seriously impressive Iron Man suit — some of the gadgets he has are ridiculous! 😮👏.

Astronomers Warn That Our Sun Is Having a “Midlife Crisis”
Posted by Raphael Ramos in category: space
Keeping Calm
Over the last four years, the brightness of the other stars fluctuated wildly, whereas the Sun stayed relatively constant, according to research published Friday in the journal Science. In fact, the difference between the Sun’s brightest and dimmest moments is a fifth the size of other stars.
“We wanted to see if the Sun is somehow different,” Max Planck Institute researcher Timo Reinhold told Inverse. “People have claimed that it’s more quiet than other stars, while others have claimed that it’s similarly active so we wanted to really boil it down to this very solar-like sample that is very similar to the Sun.”

Microsoft has autonomous boats for cleaning up the ocean. And it uses machine learning to identify trash. 😃 article.
Depending on the weather, current, and other factors a single interceptor can collect more than 11,000 pounds of debris in a day.

Autopsies Show Microplastics in Major Human Organs
Posted by Raphael Ramos in categories: bioengineering, biotech/medical, chemistry, health
It looks like micro-plastics are now found inside human bodies.
Researchers found evidence of plastic contamination in tissue samples taken from the lungs, liver, spleen and kidneys of donated human cadavers.
“We have detected these chemicals of plastics in every single organ that we have investigated,” said senior researcher Rolf Halden, director of the Arizona State University (ASU) Biodesign Center for Environmental Health Engineering.

Software spots and fixes hang bugs in seconds, rather than weeks
Posted by Saúl Morales Rodriguéz in categories: cybercrime/malcode, robotics/AI
Hang bugs—when software gets stuck, but doesn’t crash—can frustrate both users and programmers, taking weeks for companies to identify and fix. Now researchers from North Carolina State University have developed software that can spot and fix the problems in seconds.
“Many of us have experience with hang bugs—think of a time when you were on website and the wheel just kept spinning and spinning,” says Helen Gu, co-author of a paper on the work and a professor of computer science at NC State. “Because these bugs don’t crash the program, they’re hard to detect. But they can frustrate or drive away customers and hurt a company’s bottom line.”

Researchers develop new algorithm with better performance for spectral technology
Posted by Saúl Morales Rodriguéz in categories: information science, particle physics
Recently, researchers from the Institute of Intelligent Machines developed a new wavelength selection algorithm based on combined moving window (CMW) and variable dimension particle swarm optimization (VDPSO) algorithm.
CMW retained the advantages of the moving window algorithm, and different windows could overlap each other to realize automatic optimization of spectral interval width and number. VDPSO algorithms improved the traditional particle swarm optimization (PSO) algorithm.
This new algorithm, which is called VDPSO-CMW, could search the data space in different dimensions, and reduce the risk of limited local extrema and over fitting.
