A robot banishes harmful algae slicks to the ocean floor. And, according to an Australian research team, oil spills could soon be hoovered up by mini-robots. Key here: a new filter with small, air-filled pouches, coated with a water-resistant nanolayer of graphene oxide. It separates oil with 95% purity and can be extensively reused. The 3D-printed, electrically-operated mini-robot complete...

Contorting molecules can store energy for as long as necessary. Meanwhile, a Hong Kong research team has turned to tofu in its drive to develop an environmentally-friendly, durable, cost-efficient battery. Water with salts of magnesium and calcium (similar to tofu brine) created the electrolyte. Due to its pH-neutrality, it attacked neither the highly conductive polymer anode nor the Prussian...

Lighting and air-conditioning can be controlled using a ring. Now, a design studio in Amsterdam has devised a piece of jewellery that enhances digital security. Still a concept, the ring is used for verifying personal contacts. Initially, an integrated infrared-light scanner captures the blood flow through users’ finger veins. This information is converted into a personal code and stored...

Saliva provides information about possible heart failure. Alzheimer’s, meanwhile, is often diagnosed through an analysis of the cerebrospinal fluid after changes in cognitive capabilities. But loss of smell can be an initial warning sign. Enter an American research team and its new nasal swab aimed at early detection. In a 22-person study, different immune and nerve cells were removed...

Onions protect solar modules, securing their long-term output. Hemispherical solar cells could deliver even more electricity. Now a Norwegian startup’s system is enabling homeowners to harness their solar energy more efficiently and make provisions for the winter months. First, a fuel cell converts the solar energy into hydrogen. Then, using the firm’s patented technology, it is processed into a...

In the Netherlands, corn is a source of sustainable tiles. In California, however, a startup is using corn waste to create a super-absorbent and biodegradable material to replace the petrochemical liners in products like nappies and hygiene pads. The team developed special microorganisms to convert the corn’s sugar into a polymer, which can absorb as much liquid as materials...
