MIT spinoff Quaise Energy is building a drill that vaporizes rock — so that we can tap into the energy miles below our feet.

Geothermal energy: Earth’s core is as hot as the surface of the sun, but we don’t have to go too far below the surface to start feeling the heat — in the Mponeng gold mine in South Africa, which has a depth of 2.5 miles, rock temperatures can reach 140 degrees Fahrenheit.

Mangrove trees inspire thermal and membrane-based desalination system.

Four US students, taking part in a program aimed at high school girls interested in engineering, have designed a desalinating water bottle. The currently hypothetical device would be compact and portable so could offer increased accessibility over existing desalinating designs that mimic transpiration.

Laurel Hudson, Gracie Cornish, Kathleen Troy and Maia Vollen met at Virginia Tech’s C-Tech2 program where they were given an assignment to ‘reinvent the wheel’. Choosing to focus on the global water crisis and inspired by drinking straws used by hikers to purify water, they considered if it was possible to make a bottle that produced drinking water from seawater. They reached out to Jonathan Boreyko, an associate professor in the department of mechanical engineering, who was researching synthetic trees at the time. He agreed to help, and, during the height of the Covid-19 pandemic, the group met virtually at night to discuss their research. Along with Ndidi Eyegheleme, a graduate student in Boreyko’s lab, they planned and produced a model to evaluate the inner workings of their design.

Nearly 60% of adults and 75% of children have antibodies indicating that they’ve been infected with Covid-19, according to new data from the US Centers for Disease Control and Prevention.

The data come from an ongoing study of blood samples sent to commercial laboratories across the US.

At the beginning of December, an estimated 34% of Americans had antibodies showing that they had once been infected with the virus that causes Covid-19. By the end of February, after an avalanche of cases caused by the Omicron variant, that number had jumped to 58%.

Researchers from Nanyang Technological University, Singapore (NTU Singapore) have developed the capability to use recycled glass in 3D printing, opening doors to a more environmentally sustainable way of building and construction.

Glass is one material that can be 100% recycled with no reduction in quality, yet it is one of the least recycled waste types. Glass is made up of silicon dioxide, or silica, which is a major component of sand, and therefore it offers significant untapped potential to be recycled into other products.

At the same time, due to growing populations, urbanization and infrastructure development, the world is facing a shortage of sand, with climate scientists calling it one of the greatest sustainability challenges of the 21st century.

Researchers at the Max Planck Institute for Intelligent Systems (MPI-IS), Cornell University and Shanghai Jiao Tong University have developed collectives of microrobots which can move in any desired formation. The miniature particles are capable of reconfiguring their swarm behavior quickly and robustly. Floating on the surface of water, the versatile microrobotic disks can go round in circles, dance the boogie, bunch up into a clump, spread out like gas or form a straight line like beads on a string.

Each robot is slightly bigger than a hair’s width. They are 3D printed using a polymer and then coated with a thin top layer of cobalt. Thanks to the metal the microrobots become miniature magnets. Meanwhile, wire coils which create a magnetic field when electricity flows through them surround the setup. The magnetic field allows the particles to be precisely steered around a one-centimeter-wide pool of water. When they form a line, for instance, the researchers can move the robots in such a way that they “write” letters in the water. The research project of Gaurav Gardi and Prof. Metin Sitti from MPI-IS, Steven Ceron and Prof. Kirstin Petersen from Cornell University and Prof. Wendong Wang from Shanghai Jiao Tong University titled “Microrobot Collectives with Reconfigurable Morphologies, Behaviors, and Functions” was published in Nature Communications on April 26, 2022.

Cooper Bikes, the company behind the Mini Cooper car, has just unveiled four new electric bicycle models that comprise the brand’s second generation e-bikes.

Cooper Bikes is the two-wheeler division of Cooper Car Company, which was the original designer of the Mini Cooper, itself a segment of BMC’s iconic Mini.

But while the Mini Cooper helped create a name for the company as far back as 1961, today it is Cooper Bikes that is stealing the headlines with four interesting new models.
