The Waveline Magnet is an energy generator made by SWEL in Cyprus, that passively generates electricity from the movement of waves it rides on. Check out the mesmerising concept video here.
Scientists at McGill University in Canada have developed a hydrogel bandage that can be bonded to the skin using ultrasound. The application of ultrasound to the bandage stimulates micro-bubbles that bond the hydrogel molecules to the skin.
Scientists from Michigan State University have discovered that locusts can not only smell cancer cells, but changes in their brain activity that can be measured also change depending on the type of cancer cell that they smell. Harnessing this diagnostic capability could allow large scale early stage cancer detection.
Scientists at the University of Texas stored an encrypted version of The Wizard of Oz in 256 bits of data encoded within polymers of ink. The ink was used to write a letter, which can later be decoded using depolymerization and liquid chromatography-mass spectrometry equipment.
The Nuclear Regulator Commission is set to approve NuScale modular nuclear reactor for use. The NuScale reactor is small enough to be manufactured and shipped to its site of use, uses external water supplies for cooling and features an operator free shut down procedure using gravity if a problem occurs.
Researchers at Binghamton University developed a new method to extract the gold metallic layer of a CD, without toxic chemicals, and repurposed into biosensors for wearable devices.
Spanish scientist José Antonio G. I. developed a prototype system to extract hydrogen from tap water without electrolysis. Pressurized air injected into a tank of water, ferrosilicon, and sodium hydroxide causes a chemical reaction to extract the hydrogen through two additional tanks that can produce 30 litres of hydrogen per minute. Allowing hydrogen to be generated at the point of consumption removes the need for hydrogen transportation.
Switzerland have given go-ahead for the construction of the first 70km of a new underground autonomous cargo delivery system called Cargo Sous Terrain (CST) at a cost of $3 billion. The full 500km network is expected to cost $35 billion and be complete by 2045. Electric induction power cargo pods will travel on rails in the underground tunnels at 30km per hour.
Engineers at Cornell University have demonstrated how facial expressions can be detected and recreated using sonar on a wearable placed on each side of the head. A machine learning model analyses the sonar echo produced from a speaker and microphone on each ear to detect changes in skin on the face. The system effectively recognises facial expressions with the same detail as a camera.
Researchers at ETH Zurich have built and testing a solar jet fuel generator. The solar tower uses solar power, water and CO2 from the atmosphere to generate a carbon-neutral jet fuel mix that can be converted into ynthetic fuels.
