A new study modeling how effective face shields and face masks with exhaust-valves are in blocking the dispersal of aerosol-sized droplets suggests the growing use of these alternative face coverings may not be helpful in curbing the spread of COVID-19.

While autonomous drones are now pretty good at avoiding large obstacles, thin suspended power lines can still pose a challenge. A new onboard sensing system, however, could change that.

More than once, we've seen an "SUV of the high seas," and Officina Armare has a new interpretation. The 60-foot (18.3-m) Aquanaut leaves 4WD on land in favor of dual-hull navigation, bringing along more toys than an SUV ever could ever handle.

A new study is questioning whether Alzheimer’s treatments previously found to be ineffective in human trials should be re-examined, after the discovery of a specific gene that can inhibit a therapy’s efficacy is only present in 75 percent of people.

When suturing wounds within the body, there's a risk of damaging the tissue, and of the development of infections. A new surgical glue could reduce the need for sutures, though, plus it could close wounds faster while also delivering medication.

A new study has validated the efficacy of a novel AI algorithm designed to deliver accurate MRI results using a quarter of the data of current systems. This innovation promises to speed up MRI scans without upgrades to pre-existing imaging hardware.

The excavation and disposal of landmines is a time- and labor-intensive business, so it can be quite a waste of resources if the detected object is not actually a mine. A new system could help, by reducing the number of mine-hunting errors.

Video games are often associated with laziness, but they often use those engaging reward systems to help people's fitness. The latest is Quell, a game about punching your way through a fantasy world while getting a high-intensity boxing workout.

Like most machines, the human body tends to wear out faster at the points of articulation, where decades of stress are focused. Now, researchers at Stanford have found a way to induce cartilage tissue to regenerate in joints by tweaking the stem cells there.

British company Oxis says it's developed safe, high-density lithium-sulfur battery chemistry and will supply Texas Aircraft Manufacturing with a 90-kWh, next-gen battery pack to power the eColt, an electric aircraft with a two hour, 230-mile range.

Nemesis Yachts has put forward a blue-sky vision for a super-fast, hydrogen-powered, autonomous luxury catamaran that can rise out of the water on hydrofoils to achieve crazy speeds over 50 knots. Oh, and you can swap this 300-footer's cabins out.

One area where the modern smartphone has come to show incredible amounts of promise is in medical diagnostics, where they could soon reshape how we detect diabetes, gauge female fertility, spot skin cancers, and much more.
