Lighting the path to renewable energy

(Okinawa Institute of Science and Technology (OIST) Graduate University) Professor Mahesh Bandi of Okinawa Institute of Science and Technology Graduate University (OIST) has co-developed a novel, standardized way of quantifying and comparing these variations in solar power. His new study, published in Physical Review Applied, may help guide the development and performance of solar photovoltaic farms — systems that harness the sun’s energy and convert it to electricity.

Green light given to fruit fly’s color preference

Researchers have made two unexpected discoveries. First, they found that, given a choice, fruit flies are drawn to green light early in the morning and late in the afternoon, when they are most active, and to red, or dim light, in midday, when like many humans, they slow down to eat and perhaps take a siesta.

Are Saturn’s rings young or old?

Cassini data suggested that Saturn’s rings were only 10 to 100 million years old. A new study suggests that a “ring rain” onto Saturn makes the rings look younger than they really are, and that in fact Saturn’s rings date back billions of years.

What makes a red rainbow?

Have you ever seen a red rainbow? You might, if you’re outside at sunrise or sunset at a time when there’s rain in the air. Red rainbows have a surreal beauty, but their explanation is fairly ordinary. They’re created via the same physics that makes a sunset or sunrise looks red.

The sleep neuron in threadworms is also a stop neuron

(Goethe University Frankfurt) The nervous system of the threadworm C. elegans is simple at first sight: it consists of 302 neurons, some of which, however, have several functions. The neuron ‘RIS,’ known as a sleep neuron, can therefore put the worm into a long sleep — or also just briefly stop its locomotion, as a group of scientists led by Goethe University have now discovered.

Milky Way’s black hole appears to be getting hungrier

“We have never seen anything like this in the 24 years we have studied the supermassive black hole. It’s usually a pretty quiet, wimpy black hole on a diet. We don’t know what is driving this big feast.”
