Smithsonian.com covers research that began with the study of birdsong and ended by overturning the common belief that adult animals can't produce new brain cells. "Deconstructing birdsong may seem an unlikely way to shake up biology. But [Fernando] Nottebohm's research has shattered the belief that a brain gets its quota of nerve cells shortly after birth and stands by helplessly as one by one they die — a 'fact' drummed into every schoolkid's skull. [Nottebohm] demonstrated two decades ago that the brain of a male songbird grows fresh nerve cells in the fall to replace those that die off in summer. The findings were shocking, and scientists voiced skepticism that the adult human brain had the same knack for regeneration. ... Yet, inspired by Nottebohm's work, researchers went on to find that other adult animals — including human beings — are indeed capable of producing new brain cells. And in February, scientists reported for the first time that brand-new nerves in adult mouse brains appeared to conduct impulses — a finding that addressed lingering concerns that newly formed adult neurons might not function."

Wannabe Code Monkey sends along an article from the Patriot Ledger about an effort in Massachusetts to pass a "Right to Repair" bill. "Since the advent of congressionally mandated computers in vehicles more than 15 years ago (for emissions), cars have evolved into complex machines that are no longer just mechanical. Computers now monitor and control most systems in the car from brakes to tire pressure and all the electronics and engine fluids... [and] car manufacturers continue to hold back on some of the information that your mechanic needs in order to properly repair your car and reset your codes and warning lights... Massachusetts is now poised to solve this problem and car-driving consumers should pay attention this fall when the Massachusetts Legislature takes up landmark legislation that would force manufacturers to respect the right of consumers to access their own repair information. The legislation, known as Right to Repair, is seen by car manufacturers as a threat to the lucrative service business in their dealerships and they are massing their lobbyists on Beacon Hill in an effort to defeat it."

KentuckyFC writes "Gravitational waves squash and stretch space as they travel through the universe. Current attempts to spot them involve monitoring a region of space several kilometers across on Earth for the telltale signs of this squeezing. These experiments have so far seen nothing. But by monitoring an array of pulsars throughout the galaxy, astronomers should be able to see the effects of gravitational waves passing by. They say such an array of pulsars should effectively shimmer as the gravitational waves wash over it, like a grid of buoys bobbing on the ocean. That'll create an observatory that is effectively the size of the entire galaxy. These observations should be capable of monitoring how galaxies and supermassive black holes evolve together, and shed light on the physics of the early universe. Best of all, the next generation of radio-telescope arrays should be capable of making these observations at a cost of around $66 million over ten years. That's a small fraction of the hundreds of millions that Earth-based observatories have already cost."

An anonymous reader writes "My son brought home an order form from his middle school. Apparently the 7th (his grade) and 8th graders are being asked (required?) to purchase their own straps for the heart monitors they're to wear during gym class. I know nothing yet of the device in question, but have left a voice-mail with the assistant principal asking him to call me so I may ask some questions about the program and the device. My tinfoil-hat concern is that the heart rate data will be tied to each child, then archived and eventually used for/against them down the road when applying for insurance, high-stress jobs, etc. 'I see you had arrhythmia during 7th grade pickle ball? No insurance for you' Has anyone heard of such a program, or had their child(ren) take part in it? Does the device transmit to the laptop the overweight gym teacher will be watching instead of running laps with the kids? Perhaps data is downloaded from the device after the class? Or am I just being paranoid? Thanks for any insight."

BJ_Covert_Action writes to let us know that an Oregon congressman has filed legislation to spend $154.5M for a research project into tracking per-vehicle mileage in the US, and asks: "Do we really want the government to track our movement and driving habits on a regular basis?" "US Representative Earl Blumenauer (D-Oregon) introduced H.R. 3311 earlier this year to appropriate $154,500,000 for research and study into the transition to a per-mile vehicle tax system... Oregon has successfully tested a Vehicle Miles Traveled fee... the [Oregon] report urged a mandate for all drivers to install GPS tracking devices that would report driving habits to roadside RFID scanning devices." Here is the bill (PDF). The article notes that the congressman's major corporate donors would likely benefit with contracts if such a program were begun.

He outed them on Twitter. The team at Technically Legal broke down the story and the take-home messages for using other people's images."

CWmike writes "The US Department of Homeland Security is looking at a report by a research scientist in China that shows how a well-placed attack against a small power subnetwork could trigger a cascading failure of the entire West Coast power grid. Jian-Wei Wang, a network analyst at China's Dalian University of Technology, used publicly available information to model how the West Coast grid and its component subnetworks are connected. Wang and another colleague then investigated how a major outage in one subnetwork would affect adjacent subnetworks. New Scientist magazine reported on this a week or so ago, and the paper has been available since the spring."

yahoi writes "Companies around the world are leaving themselves wide open to Web- and client-side attacks, according to a new report released today by the SANS Institute that includes real attack data gathered from multiple sources. SANS found that most organizations are focusing their patching efforts and vulnerability scanning on the operating system, but they're missing the boat: 60 percent of the total number of attacks occur on Web applications, and many attacks are aimed at third-party applications such as Microsoft Office, and Adobe Flash and other tools. Exacerbating the problem, they're taking twice as long to patch Microsoft Office and other applications than to patch their operating systems."

myvirtualid writes "Con Kolivas has done what he swore never to do: returned to the Linux kernel and written a new — and, according to him — waaay better scheduler for the desktop environment. In fact, BFS appears to outperform existing schedulers right up until one hits a 16-CPU machine, at which point he guesses performance would degrade somewhat. According to Kolivas, BFS 'was designed to be forward looking only, make the most of lower spec machines, and not scale to massive hardware. i.e. [sic] it is a desktop orientated scheduler, with extremely low latencies for excellent interactivity by design rather than 'calculated,' with rigid fairness, nice priority distribution and extreme scalability within normal load levels.'"
