An inexpensive ingredient may reduce concrete’s climate impact

After water, concrete is the world’s most consumed material and is the mainstay of construction everywhere, and concrete production’s impact on the environment is significant. Researchers have discovered that introducing an inexpensive, readily availab… Continue reading An inexpensive ingredient may reduce concrete’s climate impact→

Silk-microparticle dots could help thwart seed counterfeiters

Just like pharmaceuticals, banknotes and alcoholic beverages, the crop seeds sold to farmers are frequently counterfeits. MIT scientists have devised a method of spotting the fakes, by tagging genuine seeds with silk dots.Continue ReadingCategory: Good… Continue reading Silk-microparticle dots could help thwart seed counterfeiters→

MechSense 3D-prints wireless rotational sensors right into moving parts

It’s certainly handy to know how fast gears or wheels are spinning, but equipping them with external sensors can be awkward and may affect their performance. That’s why scientists have devised a method of 3D-printing wireless sensors right into the thi… Continue reading MechSense 3D-prints wireless rotational sensors right into moving parts→

Clever MIT modular robotics system could give astronauts WORMS

No single robot can perform all tasks, yet bringing a bunch of different robots along on Moon missions would be quite inefficient. The WORMS setup offers an alternative, in the form of components that can be mixed and matched to make whatever robot is … Continue reading Clever MIT modular robotics system could give astronauts WORMS→

New kit beams images straight onto the retina from Sony camera

In an effort to help vision-impaired people enjoy taking photographs, Sony has paired with QD Laser to create a retinal projection camera kit. By bypassing the outer layers of the eyes, the kit allows those who would otherwise have difficulty doing so … Continue reading New kit beams images straight onto the retina from Sony camera→

Tractor-towed Vulcan automatically spots and pulls weeds

Nobody likes the idea of herbicides in their veggies, yet hiring workers to pick weeds by hand can be prohibitively expensive for farmers. The Vulcan farm implement offers an alternative, as it automatically spots and yanks out weeds while leaving crop… Continue reading Tractor-towed Vulcan automatically spots and pulls weeds→

MIT’s X-AR system guides users to RFID-tagged hidden items

It can be frustrating when you’re searching for an object, knowing that you may have looked right where it is without realizing you’ve done so. A new augmented reality system could help, by showing users where specific items are … even if they’re hidde… Continue reading MIT’s X-AR system guides users to RFID-tagged hidden items→

Liquid-pumping heart replicas could lead to better cardiac treatments

Before operating on someone, it would be very helpful if cardiac surgeons could examine a physical model of that specific individual’s heart. Well, they should soon be able to do so – and the model will actually pump liquid, just like the patient’s rea… Continue reading Liquid-pumping heart replicas could lead to better cardiac treatments→

MIT team makes a case for direct carbon capture from seawater, not air

Pulling greenhouse gases out of water is an odd-sounding idea, but the oceans are the planet’s number one carbon sink, and direct air carbon capture has pretty serious problems: it costs a lot, and uses a lot of energy. According to IEA figures from 20… Continue reading MIT team makes a case for direct carbon capture from seawater, not air→
