Did the Local Void shoot a monster extreme-energy cosmic ray our way?

The Earth’s atmosphere has been blasted by the second strongest ultrahigh-energy cosmic ray (UHECR) to ever be observed. While its exact origins remain unknown, astrophysicists are pointing the finger at the Local Void, a fundamentally empty area of th… Continue reading Did the Local Void shoot a monster extreme-energy cosmic ray our way?

This sea worm’s butt detaches from its body to swim off in search of love

In one of the strangest paths to reproduction, this tiny Japanese sea worm actually grows a ‘mini-me’ at its rear end, which it then deploys so it can swim off on its own in search of similar autonomous tail of the opposite sex to spawn with. The worm,… Continue reading This sea worm’s butt detaches from its body to swim off in search of love

Impressive new plastic self-heals, can be recycled and feeds marine life

Japanese scientists have developed a new type of plastic that’s strong at room temperature, but can be easily broken down on demand into its base components. In seawater, it starts to break down into food for marine life, and just to top it off, it can… Continue reading Impressive new plastic self-heals, can be recycled and feeds marine life

“Starquakes” could be behind mysterious radio signals from space

Cosmic radio signals are beaming to Earth every day – and astronomers are stumped as to their origin. Now a new study finds evidence that these signals, known as fast radio bursts (FRBs), could be caused by “starquakes.”Continue ReadingCategory: Space,… Continue reading “Starquakes” could be behind mysterious radio signals from space

Millisign tech guides autonomous drones via battery-less ground tags

When it comes to precisely locating landing pads or other landmarks, autonomous drones rely largely on visual cues. So, what happens if it’s dark, rainy or foggy, and there’s no ground-based power for lights? Well, that’s where the Millisign system is … Continue reading Millisign tech guides autonomous drones via battery-less ground tags

GPS alternative taps cosmic rays for underground or underwater navigation

GPS is a powerful navigation technology, but it doesn’t work as well inside buildings, underground or underwater. Now engineers in Japan have developed and tested an alternative technology that uses cosmic rays to track movement beneath a building with… Continue reading GPS alternative taps cosmic rays for underground or underwater navigation

Swappable Jizai Arms bring new meaning to “Could you lend me a hand?”

Equipping people with extra sets of robotic arms could definitely help them perform certain tasks, but what role might such arms play in social interactions? The wild-looking Jizai Arms were designed with that question in mind.Continue ReadingCategory:… Continue reading Swappable Jizai Arms bring new meaning to “Could you lend me a hand?”

Intensity of stars is related to the planet-creating dust they produce

Some stars produce dust. But unlike the stuff underneath your TV cabinet, this dust plays a major part in the total luminosity of a galaxy. In a new study, scientists have used long-term observational data to see how interstellar dust correlates with a… Continue reading Intensity of stars is related to the planet-creating dust they produce

Multi-segment shapeshifter drones: The precursors to flying squid-bots

Effectively, these bots are built in segments, and each segment has its own multicopter propulsion unit, capable of vectoring thrust in any direction thanks to multi-axis gimbal systems. The segments are joined together, but capable of articulating in … Continue reading Multi-segment shapeshifter drones: The precursors to flying squid-bots

Potentially useful new microalgae discovered in a home aquarium

Microalgae are widely used in products such as biofuels, nutritional supplements and cosmetics. A newly-described type has been found in a home aquarium – and it could prove to be particularly useful.Continue ReadingCategory: ScienceTags: Algae, Univer… Continue reading Potentially useful new microalgae discovered in a home aquarium
