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.
‘Tunabot: First robotic fish to keep pace with tuna
Mechanical engineers have created the first robotic fish proven to mimic the speed and movements of live yellowfin tuna.
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.
Will a huge volcano on Jupiterâs moon Io erupt this month?
Loki, the largest volcano on Jupiter’s moon Io, erupts on a more or less regular schedule. Planetary scientists are predicting an eruption this month. Here’s what we know.
Are Saturnâs 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.
Mystery green blob appears and disappears in distant galaxy
What is ULX-4 – a mystery green blob of X-ray light that appeared in the Fireworks Galaxy – and then soon disappeared again? A black hole or neutron star are 2 possibilities.
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.
Sub auroral arc over Peyto Lake, Alberta
STEVE, and the northern lights. Does it get any better than this?
Milky Wayâs 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. Itâs usually a pretty quiet, wimpy black hole on a diet. We donât know what is driving this big feast.”
