You would think that the more sunlight that hits a solar panel, the better. When it comes to efficiency though, that's not the case – as photovoltaic cells heat up their efficiency decreases. To capture that heat and put it to good use, a team of scientists from Brunel University London has created a hybrid system that turns the whole roof into a solar generator.
Though materials have been developed that clot blood in order to slow bleeding, when the bleeding is internal things get a little more complicated. The flow of blood makes it difficult to deliver these agents upstream to the site of the injury, but now a team of Canadian researchers says it may have a solution. It has developed a micro-sized particle that produces gas to propel itself against the tide.Read More
In a bid to help bring greater access to clean drinking water to the developing world, WaterStillar has created a solar-distillation system designed to produce clean drinking water from almost any source. Conceived as a cheap, efficient, modular system that can be scaled up to produce thousands of liters per day, Water Works is installed with no upfront costs and requires minimal maintenance or training to operate.Read More
If you're wondering what the best dressed sea turtles are wearing at the beach this season, then the University of Queensland has the answer. As part of a study to find the foraging areas of endangered loggerhead turtles, researchers there designed a bespoke swimsuit for the 120 kg (264 lb) animals that acts as a harness for a "giant nappy" to collect fecal samples.Read More
Earth isn't the only place with seasons. Other planets and even very small celestial bodies can have them, too, as ESA's Rosetta probe has shown in its explorations of comet 67P/Churyumov-Gerasimenko. When the unmanned spacecraft went into orbit about the comet, it revealed that the southern hemisphere of the dumbbell-shaped nucleus is shrouded in a dark winter that lasts over five years and, according to data collected by the Rosettas's onboard spectrometer, hides ice in larger amounts than the rest of the comet.Read More
NASA has released the highest resolution images to date of Pluto's moon Charon. The images were taken by the New Horizons spacecraft during its July 14 flyby of the dwarf planet, and are part of an ongoing data transfer that will see tens of gigabits of data returned over the course of the next 12 months.Read More
Researchers at Brown University have developed a way to create "mini brains" – 3D arrangements of neural tissue that are able to transmit electrical synapses – that, at 25 cents apiece after fixed costs, could provide an efficient means of conducting neuroscience research.Read More
NASA has announced the selection of five conceptual planetary exploration missions for further study ahead of a potential launch date of 2020. Selected under NASA's Discovery Program, the would be missions include the exploration of Venus and asteroids, as well as large scale analysis of near-Earth objects.Read More
Results from a new technique designed to map the structure of the Milky Way appear to support the four spiral arm model of our galaxy. A team of researchers from the Federal University of Rio Grande do Sul, Brazil, used data collected by NASA's Wide-field Infrared Survey Explorer (WISE) spacecraft to pinpoint star clusters located in the resource rich environment of the spiral arms, and use them as markers to trace the structure of our galaxy.Read More
How to improve food systems by looking to nature for design solutions – this was the brief given to entrants in the Biomimicry Institute’s Global Design Challenge, which announced its finalists this week. The selection committee has drawn up a list of eight teams, each of which has been invited to prototype its solution in an accelerator program that will award US$100,000 to the winner.
