Regulated respite

Dragonfly wings have served as inspiration for flexible splints. And it seems we could learn a thing or two from grizzly bears. Despite consuming up to 20,000 calories per day and hibernating for long periods, the animals are able to regulate their blood sugar levels. A US research team fed honey water to six hibernating grizzly bears during wake...

Effective swing

Implants can be nourished by the body's store of glucose, while batteries can be powered by air moisture. Now, using an A5-sized device, a research team from Singapore has managed to generate electricity from a light breeze. A long plate with a cube on its end is fixed to one side of a small base body. The plate vibrates...

Converted contortion

Cycling into the wind can be illuminating. A collection of small wind turbines in the ocean may generate electricity for entire towns. Using the patented technology developed by an American research team, renewable energy could soon be produced from the movement of water in the sea. Unlike mechanical systems like these, the water’s power doesn't actuate a single generator...

Influential removal

Infrared light helps wounds to heal, and a damaged retina can be restored. Meanwhile, a US research team has gained new insights into how rheumatoid arthritis might be treated in future. The chronic disease sees the immune system attack the body’s own joint tissues. Inflammatory molecules cause cells to grow rapidly, while at the same time activating proteins that...

Visible improvement

Our brains are lazy, and some people learn quicker than others. An app helps children with dyslexia. Perceiving new situations often poses challenges for people within the autism spectrum. Now, following a 30-person study, a research team in Tel Aviv has evaluated a new method of learning. On the first day, participants were asked to study a visual task...

Material charge

Body heat and sweat generated through sport can be useful. Now, a research team in Singapore has found a way of producing electricity from air moisture. First, a fabric made of wood pulp and polyester was coated with carbon nanoparticles. Hydrogel made using sea salt was applied to one half, while the other stayed dry. Positively charged sea-salt ions...

Energetic extract

Wine and shrimps are an ideal combination, particular in connection with chitin. These carbohydrates from crustacean shells aren’t just suitable for conserving foods; their potential is vast. Now, a research team from Maryland University has developed an electrolyte gel with chitosan - a bio-polymer extracted from chitin - for use in zinc batteries. In tests, their new battery showed...

Natural winner

Documenting fish stocks makes commercial fishing more sustainable. But certain organisms such as fast-growing algae create havoc for aquatic ecosystems. They deprive fish of their basis for life. Water fleas feed on algae, however, and thus have a positive impact on the natural order of things. Selecting four different genotypes of water flea, a female student from Canada examined...
