Chalmers researchers create microscopic metavehicles powered by light

Researchers from Chalmers University of Technology in Sweden have created microscopic vehicles that are powered by light. Their breakthrough was made after combining layers of an optical metasurface with a microscopic particle. After building the vehicles, they were able to use a light source to control them.

Floods from overflowing crater lakes sculpted the Martian surface

Floods from overflowing crater lakes sculpted the Martian surface

Scientists have long said that the surface of Mars shows a significant presence of water in its distant past. A new study conducted by UT Austin has found that massive floods from overflowing crater lakes played a significant role in shaping the planet's surface we know today. The team believes the flooding carved deep rifts into the surface and moved massive amounts of sediment.

FAA clears Virgin Galactic to fly after investigation

FAA clears Virgin Galactic to fly after investigation

Virgin Galactic has announced that it has been cleared to resume flight operations by the FAA. Virgin Galactic had been grounded following the conclusion of an FAA inquiry focusing on the spacecraft wandering outside of its flight clearance zone on its Unity 22 flight in July. The FAA has confirmed that Virgin had accepted the corrective actions bringing an end to the inquiry that started on August 11.

SpaceX Dragon capsule prepares to leave ISS: How to watch live

SpaceX Dragon capsule prepares to leave ISS: How to watch live

A month after docking with the International Space Station, SpaceX's Dragon capsule is preparing to detach itself from the ISS and make the relatively short trip back to Earth. The Dragon capsule was used for SpaceX's most recent ISS cargo run on behalf of NASA, supplying astronauts in orbit around the planet with the supplies they need to survive and the latest scientific investigations.

Engineers tweak ultra-wideband tech for real-time 3D motion capture

Engineers tweak ultra-wideband tech for real-time 3D motion capture

Electrical engineers from the University of California San Diego have improved on a wireless communication technology called ultra-wideband (UWB). UWB is a technology that has been around for a long time and has begun to gain popularity in recent years thanks to improved accuracy compared to Wi-Fi or Bluetooth when it comes to determining the location and movement of devices. The technology might also allow for improvements like indoor navigation and smart warehouses that know where employees and inventory are at all times.

Study finds better sleep happens with early evening workouts

Study finds better sleep happens with early evening workouts

Many people associate exercise with better sleep at night. A new study has found that exercise performed at certain times today or just before going to bed alters how people sleep. One goal of the study was to determine how exercise and sleep are linked in more detail.

New unbreakable glass was inspired by the inside of mollusk shells

New unbreakable glass was inspired by the inside of mollusk shells

Scientists from McGill University have developed a new type of glass inspired by the inner layer of mollusk shell. When the glass they have developed suffers an impact, rather than shattering like normal glass, it has resiliency similar to plastic. Researchers on the project see their new glass as ideal for covering cell phone screens and other applications.

NASA to stop sending commands to its Mars fleet

NASA to stop sending commands to its Mars fleet

NASA has confirmed that it has stopped sending commands to all of its spacecraft and rovers on the surface of Mars until the middle of October. The reason it's not sending commands to the Mars fleet is because Mars and Earth are currently on opposite sides of the sun, known as the Mars solar conjunction. This phenomenon happens every two years, and despite being unable to send commands, the missions operating on the Red Planet will continue to gather data during this period.

Major UK festival resulted in drug-laced urine threatening rare eels

Major UK festival resulted in drug-laced urine threatening rare eels

Researchers with Bangor University in Wales report that high concentrations of illegal drugs, including MDMA and cocaine, found in a river threatened wildlife in southwestern England. What caused the drugs to appear in this river? It runs through Somerset close to where the Glastonbury Festival was held -- and, more to the point, where partygoers were urinating in public.

NASA’s next super-ambitious Jupiter spacecraft is almost ready for launch

NASA’s next super-ambitious Jupiter spacecraft is almost ready for launch

NASA is readying one of its most ambitious spacecraft so far for launch next month, with Lucy set to undertake an asteroid-hopping circuit of some of Jupiter's most intriguing neighbors. The Trojan asteroids are clustered into two sizable swarms, circling around the Sun along with the vast gas giant, and the Lucy mission will be the first to study them closely.

Wind speeds in Jupiter’s iconic red spot are getting faster

Wind speeds in Jupiter’s iconic red spot are getting faster

One of the most iconic features of Jupiter is its iconic Great Red Spot. That feature is a massive storm that's been going on for centuries. Observations made using the Hubble Space Telescope have determined that wind speeds inside that massive storm have increased.

New solid-state battery uses a pure-silicon anode

New solid-state battery uses a pure-silicon anode

Engineers have created a new type of solid-state battery that leverages an anode made with pure silicon. The team says their new battery design combines two subfields of battery research to create a single battery. The battery features a solid-state electrolyte and an all-silicon anode. The result is a silicon all-solid-state battery.
