Eloking writes: In a great example of a low-cost research solution that could deliver big results, University of Michigan scientists have created a window for lithium-based batteries in order to film them as they charge and discharge.
The future of lithium-ion batteries is limited, says University of Michigan researcher Neil Dasgupta, because the chemistry cannot be pushed much further than it already has. Next-generation lithium cells will likely use lithium air and lithium sulfur chemistries. One of the big hurdles to be overcome in making these batteries practical is dendrites — tiny branch-like structures of lithium that form on the electrodes.

While this may be an annoyance to the public it seems like a reasonable countermeasure to potential terrorist threats. Is it only a matter of time before other vulnerable sites such as the White House or the Capitol in Washington start doing the same?
squiggleslash writes: Samsung is already feeling the heat from its exploding Note 7 phones, but according to The Guardian a lawsuit has been filed alleging Samsung's phones have for years shown similar defects. From the S6 to the Acclaim R880, the lawsuit covers 30 incidents where phones other than the Note 7 ignited into flames or became burning hot. The lawsuit may light a fire underneath Samsung's engineering group and force them to confront the issue.
Bookworm09 writes: PRAGUE — A man identified as a Russian hacker suspected of pursuing targets in the United States has been arrested in the Czech Republic, the police announced Tuesday evening.
The suspect was captured in a raid at a hotel in central Prague on Oct. 5, about 12 hours after the authorities heard that he was in the country, where he drove around in a luxury car with his girlfriend, according to the police. The man did not resist arrest, but he had medical problems and was briefly hospitalized, the police said in a statement.
theodp writes: Based on a sample of interviews with 1,672 students in grades 7-12, Google says its research with Gallup shows that "Black and Hispanic students are more likely than their white counterparts to be interested in learning CS". In fact, Google says it found "Black students are 1.5 times and Hispanic students are 1.7 times as likely as white students to be interested in learning CS." In response, Google has joined Microsoft, Apple, Amazon, and others to call for more K-12 CS cowbell. A just-released K–12 Computer Science Framework (pdf, 339 pgs.), which cites some of the same Google & Gallup reports President Obama drew factoids from ("Nine out of ten parents want it [CS] taught at their children’s schools") to justify his $4.2B CS For All budget request, even calls for "pair programming" lessons for the pre-Kindergartner set. "At the pre-K level," reads a chapter on Computer Science in Early Childhood Education, teachers can help facilitate pair programming among two children with the same "My turn"/"Your turn" flashcards to designate driver/navigator roles as well as encourage children to engage in collaboration and communication skills to foster peer-to-peer scaffolding. Educators can provide more support and scaffolding by engaging in child/teacher pair programming."
Okian Warrior writes: Earlier today the website DailyKos reported on a smear campaign plot to falsely accuse Julian Assange of pedophilia. An unknown entity posing as an internet dating agency prepared an elaborate plot to falsely claim that Julian Assange received US$1M from the Russian government and a second plot to frame him sexually molesting an eight year old girl.
drdread66 writes: Muography is an established technique that uses the constant global background of muons (the much heavier cousin of the electron, created during interactions between cosmic rays and the Earth's atmosphere) as an illumination source that can penetrate even dense, thick structures. This technique has been used to probe the structure inside the damaged nuclear reactor at Fukushima, image Mt. Vesuvius, and to study other pyramids. Now this technique has yielded evidence of new "voids" inside the Great Pyramid of Giza.
From the article: "Egypt's Great Pyramid of Giza could contain two previously unknown "cavities", scientists using radiography to scan the millennia-old monument said on Saturday. On Thursday, the antiquities ministry cautiously announced finding "two anomalies" in the pyramid built 4,500 years ago under King Khufu, with further tests to determine their function, nature and size."
Bob the Super Hamste writes: The BBC is reporting on the Compas assessment, Correctional Offender Management Profiling for Alternative Sanctions. This tool is used by a number of agencies to assess if someone is likely to commit additional crimes and the resulting score is used in determining bail, sentencing, or determining parole. The article points out that while the questions on the assessment do not include race the resulting score may be correlated with race but this is disputed by the software's creators. The assessment scores someone on a 10 point scale but the algorithm used to determine someone's score is kept secret. Because of this defendants are unable to effectively dispute that the score is incorrect.
DirkDaring writes: "Julian Assange's internet link has been intentionally severed by a state party. We have activated the appropriate contingency plans." Wikileaks mentioned in a tweet early Monday morning. The internet is one of the few, if not only, available ways for Julian Assange, who has been locked up in the Ecuadorian Embassy in London for more than four years, to maintain contact with the outside world.
ArtemaOne writes: Under the Fourth Amendment, Americans are protected from unreasonable searches and seizures, but according to one group of federal prosecutors, just being in the wrong house at the wrong time is cause enough to make every single person inside provide their fingerprints and unlock their phones.
Back in 2014, a Virginia Circuit Court ruled that while suspects cannot be forced to provide phone passcodes, biometric data like fingerprints doesn’t have the same constitutional protection. Since then, multiple law enforcement agencies have tried to force individual suspects to unlock their phones with their fingers, but none have claimed the sweeping authority found in a Justice Department memorandum recently uncovered by Forbes.
netbuzz writes: Whatever difficulties Donald Trump may be having among other potential voting blocs, he’s far and away the favorite presidential candidate of at least one demographic group: spammers. However, he seems to have lost significant support among that group since peaking in January. This is according to an examination of a year’s worth of spam used by an Arizona company to test anti-spam products.

Here is how Techcrunch describes a couple of features: "The Glance Clock lets you wirelessly humblebrag by displaying fitness goals of you and your frenemies on the same clock face. Before heading out, you also can conveniently check the weather."
Glance says that they have an open API, so it can be connected almost to anything directly or via IFTTT. Other than a normal consumer, how else would you use it?
