| Viagra to prevent transmission of the malaria parasite? Posted: 07 May 2015 12:39 PM PDT By increasing the stiffness of erythrocytes infected by the causal agent of malaria, Viagra favors their elimination from the blood circulation and may therefore reduce transmission of the parasite from humans to mosquitoes. This astonishing discovery could lead to a treatment to reduce the spread of malaria within a population.  |
| Lopsided star explosion holds the key to other supernova mysteries Posted: 07 May 2015 11:53 AM PDT New observations of a recently exploded star are confirming supercomputer model predictions made at Caltech that the deaths of stellar giants are lopsided affairs in which debris and the stars' cores hurtle off in opposite directions.  |
| Mercury's magnetic field is almost four billion years old Posted: 07 May 2015 11:52 AM PDT New data from MESSENGER, the spacecraft that orbited Mercury for four years before crashing into the planet a week ago, reveals Mercury's magnetic field is almost four billion years old.  |
| Hubble finds giant halo around the Andromeda galaxy Posted: 07 May 2015 10:57 AM PDT Scientists using NASA's Hubble Space Telescope have discovered that the immense halo of gas enveloping the Andromeda galaxy, our nearest massive galactic neighbor, is about six times larger and 1,000 times more massive than previously measured. What does this mean for our own galaxy? Because we live inside the Milky Way, scientists cannot determine whether or not such an equally massive and extended halo exists around our galaxy. It's a case of not being able to see the forest for the trees. If the Milky Way does possess a similarly huge halo, the two galaxies' halos may be nearly touching already and quiescently merging long before the two massive galaxies collide. Hubble observations indicate that the Andromeda and Milky Way galaxies will merge to form a giant elliptical galaxy beginning about 4 billion years from now.  |
| Proto super-star cluster discovered: A cosmic 'dinosaur egg' about to hatch Posted: 07 May 2015 08:43 AM PDT Astronomers have discovered what may be the first known example of a globular cluster about to be born: an incredibly massive, extremely dense, yet star-free cloud of molecular gas.  |
| The hairy past: Tail hair as an indicator of behavior, ecology in horses Posted: 07 May 2015 07:12 AM PDT Life style leaves chemical traces in hair. In horses, the analysis of tail hair is especially suited as the length of the hair can provide information over a long period of time. Determining the exact period of time that corresponds to a segment of hair is not trivial. Hair does not grow at the same rate in all horses. Researchers have now solved this problem. They developed a method to correctly assign individual hair growth to seasons and thus to a specific time frame.  |
| Geochemical process on Saturn's moon Enceladus linked to life's origin Posted: 07 May 2015 05:27 AM PDT New work has revealed the pH of water spewing from a geyser-like plume on Saturn's moon Enceladus. Their findings are an important step toward determining whether life could exist, or could have previously existed, on the sixth planet's sixth-largest moon.  |
| Fresh evidence for how water reached Earth found in asteroid debris Posted: 07 May 2015 05:27 AM PDT New research strongly suggests that water delivery via asteroids or comets is likely taking place in many other planetary systems, just as it happened on Earth. The quantity of water on Earth is not unique.  |
| Antioxidant effects of coffee by-products 500 times greater than vitamin C Posted: 07 May 2015 05:25 AM PDT The coffee industry plays a major role in the global economy. It also has a significant impact on the environment, producing more than 2 billion tons of coffee by-products annually. Coffee silverskin (the epidermis of the coffee bean) is usually removed during processing, after the beans have been dried, while the coffee grounds are normally directly discarded.  |
| Identifying species imperiled by the wildlife trade may require a trip to the market Posted: 04 May 2015 07:34 AM PDT Researchers found that species that are disappearing as a result of the pet trade can be identified by changes in their market prices and trade volumes -- increasing prices and decreasing availability could mean that wild populations are plummeting. Regular pet-market monitoring could help indicate when a particular species is in trouble so that measures could be taken to monitor and protect its wild population.  |
