Will There Be One Ring To Rule the 5S Home Button?

There have been rumors for about a month that the iPhone 5S home button is going to be ringed in silver. Clayton Morris even told This Week In Tech that he was “unequivocally” sure about the change , and that the home button would otherwise have the same concave design. Other leaked photos have supported the rumor, though as usual their authenticity is somewhat questionable. Read more…

400 Million Chinese Cannot Speak Mandarin

dryriver writes with this excerpt from a thought-provoking report at the BBC: “China’s Education Ministry says that about 400 million people — or 30% of the population — cannot speak the country’s national language. Of the 70% of the population who can speak Mandarin, many do not do it well enough, a ministry spokeswoman told Xinhua news agency on Thursday. The admission from officials came as the government launched another push for linguistic unity in China. China is home to thousands of dialects and several minority languages. These include Cantonese and Hokkien, which enjoy strong regional support. Mandarin — formally called Putonghua in China, meaning ‘common tongue’ — is one of the most widely-spoken languages in the world. The Education Ministry spokeswoman said the push would be focusing on the countryside and areas with ethnic minorities.” Read more of this story at Slashdot.

High-end CPU Coolers Reviewed and Compared

jjslash writes “CPU cooling units are an often-overlooked but always important side of PC building, whether you’re looking to overclock or you simply want a cool-running, silent system. It’s also easy to get lost if you aren’t an enthusiast who keeps tabs on the best options. TechSpot has rounded up 10 high-end CPU coolers (read: huge heatsinks) including top units from Noctua, Thermalright, Xigmatek, Silverstone and Thermaltake. If you’re willing to spend the cash, they rate the Noctua NH-U14S as the best overall pick. For a tighter budget, the Thermalright offerings provide the best bang for your buck.” Read more of this story at Slashdot.

Gut Bacteria In Slim People Extract More Nutrients

Beeftopia writes “Researchers discovered that inserting gut bacteria from obese people into mice without gut bacteria led to the mice becoming obese. Gut bacteria from slim people inserted into the same mice did not lead to mouse obesity. The researchers concluded (abstract) that gut bacteria from the slim people were more efficient at extracting nutrients from food than those of the obese.” Read more of this story at Slashdot.

Transparent skull implant is the next step in body mods (and medicine)

Researchers have been kicking around the idea of a cranial porthole for years – a skylight for your skull that doctors could peer through to monitor brain cancer, or treat neurological disorders. But glass is too fragile, and traditional skull implants are opaque. Now, a team of bioengineers has developed an implant using a strong, transparent material that could make brain-windows a reality.

Users Revolt Over Yahoo Groups Update

An anonymous reader writes “The new NEO format of Yahoo Groups is being rolled out to users and there is no option to go back. Users and moderators are posting messages asking Yahoo to go back to the old format. Yahoo is responding with a vanilla ‘thank you for your feedback we are working to make it better’ comment. Most posters are so frustrated that they just want the old site back. One poster writes ‘Yahoo has effectively destroyed the groups, completely, themselves.'” Read more of this story at Slashdot.

Sleep Found To Replenish a Type of Brain Cell

New submitter wrackspurt writes “Sleep deprivation has long been thought to be prevalent in the industrialized world. A new study (abstract) explains one very good reason why at least seven hours of sleep a night is necessary. Quoting the BBC: ‘Sleep ramps up the production of cells that go on to make an insulating material known as myelin which protects our brain’s circuitry. … The increase was most marked during the type of sleep that is associated with dreaming – REM or rapid eye movement sleep — and was driven by genes. In contrast, the genes involved in cell death and stress responses were turned on when the mice were forced to stay awake.'” Read more of this story at Slashdot.
