LIVE SCIENCE - The earliest known animal to show evidence of an asymmetrical body lived over half a billion years ago in what is now the Australian outback, a new study reports. The 555 million-year-old creature, dubbed Quaestio simpsonorum in a study published Sept. 3 in the journal Evolution and Development, was able to move...
FORBES - Carbon Dioxide is often vilified as a bugaboo greenhouse gas. But its presence here on early earth is likely one of the reasons we are here to talk about it. Carbon dioxide, or CO2, was likely needed in large quantities in earth’s early atmosphere to raise temperatures sufficiently to enable the onset of...
SCIENCE NEWS - As dust from the Sahara blows thousands of kilometers across the Atlantic Ocean, it becomes progressively more nutritious for marine microbes, a new study suggests. Chemical reactions in the atmosphere chew on iron minerals in the dust, making them more water soluble and creating a crucial nutrient source for the iron-starved seas...
SCIENCE ALERT - Dust swept from the Sahara desert provides life at the bottom of the marine food chain with a critical nutrient. Without the iron carried far and wide in this mineral cloud, oceanic phytoplankton would struggle to bloom. According to a new study led by the University of California, Riverside, the more time...
THE NEW YORK TIMES - In six billion years the sun will expand into a red giant. That process should consume Mercury, and maybe Venus. For a long time we have thought it might incinerate Earth, too. But perhaps all is not doomed for planet Earth (although it may be a world that will have...
FRONTIERS - Scientists from the US measured the relative amounts of ‘bioreactive’ iron in four sediment cores from the bottom of the Atlantic. They showed for the first time that the further dust is blown from the Sahara, the more iron in it becomes bioreactive through chemical processes in the atmosphere. These results have important...
THE NEW YORK TIMES - The snow-blanketed peaks, fishing holes and cool alpine air of the San Bernardino Mountains have beckoned Southern Californians for generations. As far back as the 1880s, travelers braved a 6,000-foot climb in horse-drawn carriages to reach the pine forests that now surround the resort towns of Lake Arrowhead and Big...
THE MERCURY NEWS - Climate change didn’t light the match, but it likely set the stage for the Airport, Bridge and Line fires to burn fiercely and aggressively throughout Southern California, say academics and the head of an environmental group. As of Friday afternoon, Sept. 13, the three blazes had consumed more than 113,000 acres...
THE U.S. SUN - Scientists have created a 3D illustration charting a list of nearby stars that may be hosting "habitable" alien worlds. They used data from Nasa's Chandra X-ray Observatory to identify these planets. It involved finding stars that are close enough to Earth that we could use future telescopes to take images of...
LIVE SCIENCE - NASA's Chandra X-ray space telescope has created a three-dimensional map of stars close to the sun that may help astronomers search for alien planets that could host life. The map created by Chandra — which just celebrated 25 years in orbit but is facing a troubling budget crunch — could inform scientists...
