The vast majority of plastic waste can’t be recycled, meaning it ends up in landfills or the ocean. To help curb the problem, researchers at Berkeley Lab have now designed a new type of plastic that can apparently be reduced right back to its molecular parts, before being remade over and over.

A thousand-year-old pouch in Bolivia has revealed traces of several psychoactive compounds, indicating not only some of the earliest archeological evidence of ayahuasca use but also other intoxicants. The find suggests significant plant knowledge and a broad ancient plant trading network.

"Hypersaline brine" is industrial waste-water with salt levels that exceed even that of seawater. It’s a big, expensive, destructive problem which a team of engineers at Columbia University in New York City hope to solve with their solvent-based method of desalination.

Following the devastating fire that damaged the Notre-Dame de Paris cathedral, Vincent Callebaut Architectures has unveiled its vision for the iconic building's restoration. The firm imagines it being topped by a new glass roof and a spire, and for it to receive a significant sustainable upgrade.

​Just as new uses for drones continue to surface (both good and bad), so too do ways to stop them in their tracks. Intended for authorities looking to control sensitive airspace, the DroneBullet takes a rather heavy-handed approach, knocking suspicious aircraft clean out of the sky.​

Raytheon is developing what is billed as a universal remote for the US Navy that will allow a single unit to control a wide range of unmanned vehicles, saving space onboard ships as well as making pilot training easier.

Since 2016, a research team has been exploring the strange hypothesis that external exposure to light flickering at 40 Hz can reverse the neurodegeneration associated with Alzheimer's disease. A new study has now homed in on exactly how, on a cellular level, this light treatment could be working.

Imagine talking to someone across a crowd of thousands without using a phone, or sitting way up the back at a concert, but hearing everything perfectly. This is the promise of acoustic lenses, and researchers at the universities of Sussex and Bristol in the UK think they’ve something to shout about.

A London-based design team has combined a love of engineering, drawing and cameras to create one of the most elegant tools for drawing circles seen to date. Dubbed "Iris," this ingenious compass is part objet d’art, part engineering wonder, and part Spirograph for grown-ups.

A team of chemists from the University of California, Davis, recently demonstrated a new synthetic analogue of cannabidiol (CBD) may be just as effective for medicinal uses as its naturally extracted counterpart. This synthetic CBD compound also promises to be easier, cheaper and faster to produce.

​Several years ago, California-based Willow Garage introduced a two-armed wheeled robot known as the PR2. It was designed for use in robotics research, but unfortunately the company has since gone out of business. Quebec-based Kinova Robotics has stepped in to fill the gap, however, with its Movo.

The largest Overland Expo ever, the 2019 show welcomed more than 22,000 attendees and 1,500 registered vehicles. We've seen the camper vans of the show, and here we take a tour of everything from neatly packaged utility vehicle campers, to big expedition trucks, to an amphibious Russian rover.
