Bumpers on boats are helping to keep waterways clean. Now a young English couple is removing rotting yachts from Cornwall’s riverbanks. Their non-profit organisation’s focus: the abandoned fibreglass vessels from whose hulls plastic particles and toxic materials have leaked into surrounding waters. Recent on-site analysis showed there were more than 11,000 fibreglass shards in a single kilogram of oysters....

Smart ‘pinecones’ warn against wildfires. When it comes to domestic fires or break-ins, however, deaf people are particularly vulnerable. Enter a British research team and its new vibrating pillow jacket. On the reverse four miniature haptic actuators have been woven into the fabric. These are coupled with a smartphone through a microcontroller; the smartphone, in turn, can be connected...

Microplastics can be filtered during washing, while schoolchildren have already invented ivy-based detergents. Now, a startup in Taiwan has reinterpreted and patented an existing process so that industrial-scale washing can take place without the use of chemical detergents. Their device is installed prior to the inlet of the machine and treats tap water using electrolysis. This generates nano-bubbles with...

A nature-inspired gripper works particularly well on uneven surfaces. Endoscopic surgery, in which suspicious tissue is removed for safety reasons, relies on doctors’ ‘touch’. But touch is a precarious thing. Enter a US research team and its soft sensors that can measure force during minimally invasive procedures. The sensors are 3D-printed, moulded and made from silicone. Each contains tiny,...

Waste wood isn’t just suitable as a sustainable polystyrene substitute. Now, a Finnish research team has created an alternative to petroleum-based resin using sawdust and straw. The presence of petroleum-based bonding agents makes it tricky to recycle composites, which are used for wind turbines, boats and RVs. The team extracted cellulose and hemicellulose from the waste wood, successfully developing...

Experienced hackers can be exposed. Password vaults help people remember the many logins required to access online services. But even they aren’t completely risk-free. Cue a Texas-based research team and its browser extension, which allows users to dispense with passwords save for a single master one. When visiting a website, the extension must first be activated and the master...
