Eco-friendly sound absorbers from seaweed

Posted: 14 Jul 2022 11:50 AM PDT

From airplanes to apartments, most spaces are now designed with sound-absorbing materials that help dampen the droning, echoing and murmuring sounds of everyday life. But most of the acoustic materials that can cancel out human voices, traffic and music are made from plastic foams that aren't easily recycled or degraded. Now, researchers have created a biodegradable seaweed-derived film that effectively absorbs sounds in this range.

Nanotube-embedded coating detects threats from wear and tear in large structures

Optimized light paths, high-throughput laser scribing and the use of established coating processes paves the way to commercial viability.

Waves in the maze of no return: Anti-reflective structure for perfect transmission

Posted: 14 Jul 2022 07:30 AM PDT

Researchers have developed a surprising method to eliminate wave reflections. The method allows the calculation of a tailor-made anti-reflective structure. It can be used, for example, to design an additional layer to a wall that is only partially permeable to a wireless signal so that the entire signal can be channeled through the wall without reflections.

Action of drug compounds in tissue revealed by new technique

A new technique that can analyze how drug molecules bind to proteins in tissue samples could offer an improved route to drug discovery and development.

Virtual reality app trial shown to reduce common phobias

Posted: 14 Jul 2022 06:11 AM PDT

The trial studied phobia patients using a headset and a smartphone app treatment programme -- a combination of Virtual Reality (VR) 360-degree video exposure therapy and cognitive behavioural therapy (CBT).

Researchers use quantum-inspired approach to increase lidar resolution

Posted: 13 Jul 2022 12:42 PM PDT

Researchers have shown that a quantum-inspired technique can be used to perform lidar imaging with a much higher depth resolution than is possible with conventional approaches. Lidar, which uses laser pulses to acquire 3D information about a scene or object, is usually best suited for imaging large objects such as topographical features or built structures due to its limited depth resolution.

Off-road motorcycles put four times more kids in hospital than quad-bikes
