The RoBoat project is planning to get autonomous boats on the waters to ferry passengers and cargo, join together to form temporary floating structures, and monitor the environment. Now the design has been tweaked to be make them smarter, more agile and easier to manufacture.

A team of researchers at MIT has produced a new system that combines engineered bacteria that can detect intestinal bleeding with an ingestible electronic circuit that can wirelessly send a signal to a computer.

Once again, Overland Expo was awash with off-road expedition trailers - from lifting, sliding shape-shifters, to military-grade blocks of off-road destruction. If you want to explore the muddiest, rockiest parts of the world and tow a home with you, the show had a trailer for you.

​While there already are materials that change color in response to UV exposure, those color-changes involve reorganization of the material's molecular structure, so it can only be used a few times. A new material known as SensoGlow, however, can be used to detect and measure UVs over and over.

​You know those displays of labelled insects stuck on pins? Well, they decay over time, and sometimes even get eaten BY an insect known as the museum beetle. That's why German scientists have created a more permanent alternative – an automated 3D scanner designed specifically for imaging insects.

Few tiny homes offer the headroom of the recently completed Journey by Alabama Tiny Homes. The high ceiling throughout gives this pint-sized dwelling a relatively spacious interior, something inhabitants will likely appreciate when it comes time to crawl into bed.

Getting your groove going with a modular synth can involve lots of patch cables or a screen full of intimidating controls. Industrial designer Colin Hearon has come up with an interactive, modular synthesis device called Tone Lab where players young or old stack up components to generate sound.

NASA's InSight spacecraft has completed its first major course correction, setting it on its way to Mars. On May 22, the unmanned probe made a 40-second burn to not only alter the probe's trajectory, but to also protect the Red Planet from biocontamination by the mission's Centaur rocket booster.

​When rain water runs down city streets and into storm sewers, it can be carrying a lot of filth with it – filth such as E. coli bacteria, which may end up in rivers. There could be an inexpensive and efficient new way of ridding the water of that bacteria, however, using chips of waste steel.

Considering that Borealis Tiny Homes is based in chill Prince George, Canada, it makes sense for the firm to ensure its Aspen model is able to stand up to cold weather. The compact dwelling has several features designed to keep the frost at bay, including radiant underfloor heating.

An international team of astronomers has now found evidence of a celestial smash-up between the Milky Way and an unknown dwarf galaxy that took place around eight to 10 billion years ago, and forever changed the face of our home galaxy.

For some migraine sufferers, the pain is preceded by visual artefacts called aura, triggered by a wave of electrical activity in the brain. Now researchers have found a way to counter and slow the spread of those signals, which could be the first step towards preventing or lessening migraines.
