Can Electric Current Make People Better At Math? 112

cold fjord sends this excerpt from the Wall Street Journal: "In a lab in Oxford University's experimental psychology department, researcher Roi Cohen Kadosh is testing an intriguing treatment: He is sending low-dose electric current through the brains of adults and children as young as 8 to make them better at math. A relatively new brain-stimulation technique called transcranial electrical stimulation may help people learn and improve their understanding of math concepts. The electrodes are placed in a tightly fitted cap and worn around the head. ... The mild current reduces the risk of side effects, which has opened up possibilities about using it, even in individuals without a disorder, as a general cognitive enhancer. Scientists also are investigating its use to treat mood disorders and other conditions. ... Up to 6% of the population is estimated to have a math-learning disability called developmental dyscalculia, similar to dyslexia but with numerals instead of letters. [In an earlier experiment, Kadosh] found that he could temporarily turn off regions of the brain known to be important for cognitive skills. When the parietal lobe of the brain was stimulated using that technique, he found that the basic arithmetic skills of doctoral students who were normally very good with numbers were reduced to a level similar to those with developmental dyscalculia. That led to his next inquiry: If current could turn off regions of the brain making people temporarily math-challenged, could a different type of stimulation improve math performance?"

Massive New Cambrian-Era Fossil Bed Found 108

jfbilodeau sends word of a massive new trove of fossils located in Canada, which scientists say will rival the acclaimed Burgess Shale fossil bed. The rock formation inside which both fossil sites were found is roughly 505 million years old (abstract). The fossils provide insight into the Cambrian explosion, a time that brought the rapid appearance and diversification of many animal forms. "In just two weeks, the research team collected more than 3,000 fossils representing 55 species. Fifteen of these species are new to science." Paleontologist Jean-Bernard Caron said, "The rate at which we are finding animals — many of which are new — is astonishing, and there is a high possibility that we'll eventually find more species here than at the original Yoho National Park site, and potentially more than from anywhere else in the world." The fossils at the new site are about 100,000 years younger and are better preserved than those at the renowned Burgess shale site.

Red Hat Hires CentOS Developers 91

rjmarvin writes "Karanbir Singh and a handful of other CentOS developers are now full-time Red Hat employees, working in-house on the CentOS distribution with more transparent processes and methods. None of the CentOS developers will be working on Red Hat Enterprise Linux. The CentOS project would become another distribution and community cared for by Red Hat, like Fedora, and Red Hat CTO Brian Stevens says the company is planning its future around OpenStack, not just Linux."

Death Hovers Politely For Americans' Swipe-and-Sign Credit Cards 731

schwit1 writes "U.S. banks and merchants are shifting to a more secure way of authorizing credit card transactions in which customers will enter a personal identification number (PIN) at checkout instead of signing a receipt. The US is the last major market in the world using the signature system, which is part of the reason why a disproportionate amount of credit card fraud happens here. The change is especially relevant given the massive fraud perpetrated against customers of Target in the fall. During a Congressional hearing last week, Target CFO John Mulligan said the company is accelerating the $100 million effort to switch to the so-called "chip and pin" system. The change won't happen all at once. Banks must issue cards with microprocessors and merchants need the right equipment to process the chip and PIN transactions, which is likely to happen gradually. But Visa, American Express, and MasterCard have announced that banks and merchants that have not adopted the technology for face-to-face transactions by October 2015 will be liable for fraudulent purchases. That's a strong incentive to get up to date. The new system will also prepare merchants and banks to transition to contactless payments in the near future."

How Blogs Are Changing the Scientific Discourse 136

quax writes "Mainstream media always follows the same kind of 'He said, she said' template, which is why even climate change deniers get their say, although they are a tiny minority. The leading scientific journals, on the other hand, are expensive and behind pay-walls. But it turns out there are places on the web where you can follow science up close and personal: The many personal blogs written by scientists — and the conversation there is changing the very nature of scientific debate. From the article: 'It's interesting to contemplate how corrosive the arguments between Bohr and Einstein may have turned out, if they would have been conducted via blogs rather than in person. But it's not all bad. In the olden days, science could easily be mistaken for a bloodless intellectual game, but nobody could read through the hundreds of comments on Scott's blog that day and come away with that impression.'"

Adjusting GPAs: A Statistician's Effort To Tackle Grade Inflation 264

An anonymous reader writes "A recent analysis of 200 colleges and universities published in the Teachers College Record found 43 percent of all letter grades awarded in 2008 were A's, compared to 16 percent in 1960. And Harvard's student paper recently reported the median grade awarded to undergraduates at the elite school is now an A-. A statistician at Duke tried to make a difference and stirred up a hornet's nest in the process."

From what I see, engineers are not well paid; certainly not paid enough for what they do. The comparison with managers is specious: engineers should be paid more than managers, because the work they do is more valuable.

Dyson has seriously misunderstood the problem. There is no shortage of engineers. There is just a shortage of engineers willing to work for peanuts.

First New Generic Top Level Domains Opening 198

umdenken points out that the first batch of generic Top Level Domains will go live within the next several days, including .bike, .guru, .clothing, .holdings, .singles, .plumbing, and .ventures. (Early access began Jan. 29th.) ICANN CEO Fadi Chehade says there is currently huge demand for ICANN to reopen their program to let companies run their own gTLD. He said, "Many, many brands and many, many communities didn't know about the GTLD program. I get significant amounts of questions about when can we open the next round, because certainly there is a bit of angst that if Canon [who applied for the .canon gTLD] uses this to do an incredible mass customization campaign to win users to their product, I'm sure the brand next to them will say "Why aren't we doing this?" So I do believe this will snowball. But many will find a .com or whatever they have now will be good enough, and I believe that one excludes the other." He also said the $185,000 price tag to do so is likely to drop.

The JavaScript Juggernaut Rolls On 505

JThaddeus writes "An article in TechWorld Australia summarizes the latest opinions on JavaScript from ThoughtWorks: 'There is no end in sight to the rise of JavaScript... "I think JavaScript has been seen as a serious language for the last two or three years; I think now increasingly we're seeing JavaScript as a platform," said Sam Newman, ThoughtWorks' Global Innovation Lead.' The article touches on new additions to JavaScript tools, techniques, and languages built on JavaScript. As the fuller report (PDF) says, 'The ecosystem around JavaScript as a serious application platform continues to evolve. Many interesting new tools for testing, building, and managing dependencies in both server- and client-side JavaScript applications have emerged recently.'"

Startup Out of MIT Promises Digital Afterlife — Just Hand Over Your Data 241

v3rgEz writes "A new startup out of MIT offers early adopters a chance at the afterlife, of sorts: It promises to build an AI representation of the dearly departed based on chat logs, email, Facebook, and other digital exhaust generated over the years. "Eterni.me generates a virtual YOU, an avatar that emulates your personality and can interact with, and offer information and advice to your family and friends after you pass away," the team promises. But can a chat bot plus big data really produce anything beyond a creepy, awkward facsimile?"
