jason-za writes with this quote from a Google announcement: "People tell us all that time that they're getting more and more mail and often feel overwhelmed by it all. We know what you mean — here at Google we run on email. Our inboxes are slammed with hundreds, sometimes thousands of messages a day — mail from colleagues, from lists, about appointments and automated mail that's often not important. It's time-consuming to figure out what needs to be read and what needs a reply. Today, we're happy to introduce Priority Inbox (in beta) — an experimental new way of taking on information overload in Gmail."

joabj writes "Now that Facebook has amassed more than 500 million users, a growing number of open source social networking developers are wondering if Facebook's photo sharing, status updates and other features wouldn't work better as Internet-wide standardized services. At the OSCON conference last week, the head of Identi.ca, an open source Twitter-like microblogging service, likened today's social networking services to the enormously proprietary online services of the early 1990s, like AOL or Prodigy. He suggested that just like SMTP and Sendmail standardized what were previously propriety e-mail services, so too could open source social networking stacks, like OStatus, render walled garden services like Facebook obsolete."

pdragon04 writes to tell us that in recent tests a Howard Hughes Medical Institute team has found that through exposure to "young" blood cells, bone marrow stem cells start to act young again as well. "The researchers have not yet isolated the blood-borne factors that can switch old stem cells back to a more youthful state, but their results are consistent with other recent studies that show stem-cell aging may be reversible. Together those results suggest that it might one day be possible to boost the practical lifespan of stem cells, and thereby increase the body’s resistance to disease and age-related degeneration."

goldaryn writes "Word from the BBC today is that Europe's biggest space company is seeking partners to help get a satellite-based solar power trial into orbit: 'EADS Astrium says the satellite system would collect the Sun's energy and transmit it to Earth via an infrared laser, to provide electricity. Space solar power has been talked about for more than 30 years as an attractive concept because it would be 'clean, inexhaustible, and available 24 hours a day.' However, there have always been question marks over its cost, efficiency and safety. But Astrium believes the technology is close to proving its maturity.'"

Hugh Pickens writes "BBC reports that Markus Haering's company had been working with the authorities in Basel, Switzerland to try to convert the heat in deep-seated rocks into electricity, but the project was suspended in 2006 when drilling triggered earthquakes, one of them with a magnitude of 3.4, leading Haering's company to pay out $9M in damages. Haering's team planned to drill a series of holes penetrating up to 3 miles (4.8 km) underground with water being pumped onto rocks with a temperature of more than 195C. Basel's location on top of a fault line – the upper Rhine trench – had been deliberately chosen because the heat was closer to the Earth's surface. A risk assessment has since shown that the prospect of further quakes is too high to continue drilling in the city. Haering faces up to five years in prison if the judge finds he intentionally damaged property. Haering has admitted the 3.4 magnitude earthquake was stronger than he had expected and that his team 'had very little knowledge of seismicity' before starting to drill, but called the quakes 'a learning process for everyone involved.' Despite Haering's trial, the Swiss appetite for geothermal projects has not diminished. Engineers are beginning preliminary drilling in Zurich to see whether that area was suitable for a similar scheme, and St. Gallen, in eastern Switzerland, plans to start work on its own geothermal project next year. Drilling efforts are being closely watched in the US, where the energy department is sponsoring more than 120 geothermal energy projects in several states."
