Keeping track of white blood cell levels in chemotherapy patients is an involved but crucially important task. The treatment can lead to suppression of the immune system, a decline in white blood cell count, which in turn can give rise to infections and other serious complications. As things stand, patients are subjected to regular blood tests as a means of keeping an eye on things, but an international team of scientists has a less invasive alternative in the works. With the ability to tally up white blood cells through the skin in real time, the new testing device can simply be stuck onto a fingertip to help clinicians tailor personalized and more timely treatments.
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.
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.
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.
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.
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.
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.
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.
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.
