NASA Scientists Paint Stark Picture of Accelerating Sea Level Rise

Slashdot - Thu, 27/08/2015 - 9:05pm
A NASA panel yesterday announced widely reported finding that global sea levels have risen about three inches since 1992, and that these levels are expected to keep rising as much as several more feet over the next century -- on the upper end of model-based predictions that have been made so far. From the Sydney Morning Herald piece linked above: NASA says Greenland has lost an average of 303 gigatons [of ice] yearly for the past decade. Since it takes 360 gigatons to raise sea level by a millimetre, that would suggest Greenland has done this about eight times over just in the last 10 years or so. "People need to be prepared for sea level rise," said Joshua Willis, an oceanographer at NASA's Jet Propulsion Laboratory in La Cañada Flintridge. "It's not going to stop."

Former Apple CEO Creates an iPhone Competitor

Slashdot - Thu, 27/08/2015 - 8:22pm
An anonymous reader links to Fast Company's profile of Obi Worldphone, one-time Apple CEO John Sculley's venture into smartphones. The company's first two products (both reasonably spec'd, moderately priced Android phones) are expected to launch in October. And though the phones are obviously running a different operating system than Apple's, Sculley says that Obi is a similarly design-obsessed company: "The hardest part of the design was not coming up with cool-looking designs," Sculley says. "It was sweating the details over in the Chinese factories, who just were not accustomed to having this quality of finish, all of these little details that make a beautiful design. We had teams over in China, working for months on the floor every day. We intend to continue that process and have budgeted accordingly." Obi is also trying to set itself apart from the low-price pack by cutting deals for premium parts. "Instead of going directly to the Chinese factories, we went to the key component vendors, because we know that ecosystem and have the relationships," Sculley says. "We went to Sony. It’s struggling and losing money on its smartphone business, but they make the best camera modules in the world."

Brazil's national oral health policy: An example for other nations

Science Daily - Thu, 27/08/2015 - 7:45pm
Brazil is the only country with more than 200 million inhabitants that has a universal health system, funded by federal, state and municipal budgets. In recent decades, the system has evolved from an exclusionary to a universal model, the unified health system (Sistema Único de Saúde [SUS]), where everyone is entitled to healthcare and the government is required to provide it. Primary healthcare is the backbone of the new system, in keeping with the guidelines set forth by the Primary Healthcare Reform, recommended by the Pan American Health Organization/World Health Organization.

Astrophysicist find supermassive black holes in quasar nearest Earth

Science Daily - Thu, 27/08/2015 - 7:45pm
Astrophysicists have found two supermassive black holes in Markarian 231, the nearest quasar to Earth. The discovery of two supermassive black holes -- one larger one and a second, smaller one -- are evidence of a binary black hole and suggests that supermassive black holes assemble their masses through violent mergers.

Humans may be harmed by endocrine disrupting chemicals released during natural gas mining

Science Daily - Thu, 27/08/2015 - 7:44pm
More than 15 million Americans live within one mile of unconventional oil and gas (UOG) operations that combine directional drilling and hydraulic fracturing, or 'fracking,' to release natural gas from underground rock. Researchers have reviewed research on health effects associated with UOG operations and concluded these activities have potential for environmental release of a complex mixture of endocrine disrupting chemicals that could potentially harm human development.
