Hourglass-shaped silicon photodiodes with an enhanced near-infrared photoresponse

Silicon photodiodes are semiconductor devices commonly used to detect visible light and measure its intensity, color and position. The fact that these devices are made of silicon has both advantages and disadvantages.

Researchers design an improved pathway to carbon-neutral plastics

Researchers from U of T Engineering and Caltech have designed a new and improved system for efficiently converting CO2, water, and renewable energy into ethylene—the precursor to a wide range of plastic products, from medical ...

To navigate, flies make flexible mental maps of the world

In a circular arena, a fruit fly navigates a virtual landscape illuminated by black and blue lights. The fly is tethered in place, able to flap its wings but not move its head. Images on the wall rotate to give the illusion ...

Climate impacts 'to cost world $7.9 trillion' by 2050

Climate change could directly cost the world economy $7.9 trillion by mid-century as increased drought, flooding and crop failures hamper growth and threaten infrastructure, new analysis showed Wednesday.

New hybrid device can both capture and store solar energy

Researchers from the University of Houston have reported a new device that can both efficiently capture solar energy and store it until it is needed, offering promise for applications ranging from power generation to distillation ...

Bot can beat humans in multiplayer hidden-role games

MIT researchers have developed a bot equipped with artificial intelligence that can beat human players in tricky online multiplayer games where player roles and motives are kept secret.

When grown right, palm oil can be sustainable

Turning an abandoned pasture into a palm tree plantation can be carbon neutral, according to a new study by EPFL and the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL). These findings, based on measurements ...

NASA observes tropical storm Fung-Wong organize

As Tropical Depression 28W continued organizing and developing into Tropical Storm Fung-Wong in the Philippine Sea, NASA's Aqua satellite provided data on the storm to forecasters. In the Philippines, Fung-Wong is known as ...

The good side of carbon monoxide

Most people think of carbon monoxide as harmful, and with good reason—the colorless, odorless gas sends 50,000 people in the U.S. to hospitals each year when their furnaces malfunction or car engines run in poorly ventilated ...

Yeasts in nectar can stimulate the growth of bee colonies

Researchers from KU Leuven have found that the presence of yeasts can alter the chemical composition and thus the nutritional value of nectar for pollinators such as bees. Moreover, the study found that yeasts can even boost ...

Dog and sheep bones help injured pigeons fly again

Sheep and dog bones can be whittled into orthopedic pins that stabilize pigeons' fractured wings, helping the fractures to heal properly without follow-up surgery. Researchers describe the treatment, which is cheaper and ...

Icebergs as a source of nutrients

Sea creatures, whether large or small, need nutrients. The supply mechanism delivering these nutrients is very different in different parts of the ocean, there are nutrient-rich coastal areas, but also very nutrient-poor ...
