Solar panels made from food waste win inaugural James Dyson Sustainability Award

Posted by in categories: engineering, food, solar power, sustainability

Engineering student Carvey Ehren Maigue has been named the James Dyson Awards first-ever global sustainability winner for his AuReus system, in which waste crops are turned into cladding that can generate clean energy from ultraviolet light.

Unlike traditional solar panels, which only work in clear conditions and must face the sun directly because they rely on visible light, the translucent AuReus material is able to harvest power from invisible UV rays that pass through clouds.

As a result, it is able to produce energy close to 50 per cent of the time according to preliminary testing, compared to 15 to 22 per cent in standard solar panels.

LED Developed That Can Be Integrated Directly Into Computer Chips

Posted by in categories: computing, mobile phones

The advance could cut production costs and reduce the size of microelectronics for sensing and communication.

Light-emitting diodes — LEDs — can do way more than illuminate your living room. These light sources are useful microelectronics too.

Smartphones, for example, can use an LED proximity sensor to determine if you’re holding the phone next to your face (in which case the screen turns off). The LED sends a pulse of light toward your face, and a timer in the phone measures how long it takes that light to reflect back to the phone, a proxy for how close the phone is to your face. LEDs are also handy for distance measurement in autofocus cameras and gesture recognition.

Scientists Find Remarkable New Snake Species in Philippines

Posted by in category: sustainability

The Waray dwarf burrowing snake lives a fossorial lifestyle and likely has a diet that is specialized on earthworms or other limbless invertebrates.

It has a maximum total length of 17.2 cm (6.8 inches), making it the smallest known species in the snake superfamily Elapoidea.

“The Waray dwarf burrowing snake has among the fewest number of vertebrae of any snake species in the world, which is likely the result of miniaturization and an adaptation for spending most of its life underground,” said Jeff Weinell, a doctoral candidate in the Department of Ecology and Evolutionary Biology and the Biodiversity Institute at the University of Kansas.

UV-LED disinfection of Coronavirus: Wavelength effect

Posted by in categories: biotech/medical, computing

UV light-emitting diodes (UV LEDs) are an emerging technology and a UV source for pathogen inactivation, however low UV-LED wavelengths are costly and have low fluence rate. Our results suggest that the sensitivity of human Coronavirus (HCoV-OC43 used as SARS-CoV-2 surrogate) was wavelength dependent with 267 nm ~ 279 nm 286 nm 297 nm. Other viruses showed similar results, suggesting UV LED with peak emission at ~286 nm could serve as an effective tool in the fight against human Coronaviruses.

A New Species Dubbed the Prehistoric ‘Sea Dragon’ Discovered in English Channel

Posted by in category: futurism

A new, mysterious small marine reptile from 150 million years ago, known as the Thalassodraco etchesi or Etches sea dragon, was recently discovered in a Late Jurassic deep marine deposit along the English Channel coastline in Dorset, England. As reported by SciTech Daily, this species may have been able to dive to extreme depths, and was determined to be part of the group known as the ichthyosaurs, which are “streamlined marine predators from the Late Jurassic period.”

Capella Space unveils super-sharp radar images of Earth (photos)

Posted by in category: space

They’re the sharpest commercially available radar shots of our planet.


Capella Space’s first fully operational satellite has snapped some breathtaking images of Earth during its first few months in orbit.

The Capella-2 synthetic aperture radar (SAR) satellite, previously known as Sequoia, launched atop a Rocket Lab Electron booster on Aug. 30. Because Capella-2 captures imagery using radio waves rather than visible light, the spacecraft can both peer through clouds and study swaths of our planet that are cloaked in darkness.

NASA astronaut Kate Rubins harvests radishes grown in space

Posted by in categories: food, habitats, space

NASA astronaut Kate Rubins harvested fresh radishes grown in space, opening new doors for producing food in microgravity to sustain future longer-term missions to the moon and Mars.

The radishes were grown in the Advanced Plant Habitat (APH) aboard the International Space Station. NASA shared a time-lapse video of the radishes as they grew inside the APH over the course of 27 days.

A crewless boat is recreating the Mayflower’s 400-year-old journey, with the help of artificial intelligence

Posted by in category: robotics/AI

To commemorate the anniversary, another vessel is recreating that voyage, with the help of artificial intelligence.

“We don’t know how it’s going to go. Is it going to make it across the Atlantic?” software engineer and emerging technology specialist Rosie Lickorish told CBS News’ Roxana Saberi. “Fingers crossed that it does have a successful first voyage.”

The vessel, docked in the harbor of Plymouth, England, will rely on the latest navigation technology when it sets out to sea — but it won’t be carrying a crew or captain.
