Submission + - Noise can knock drones out of the air mid-flight->

An anonymous reader writes: Researchers are proving that drones can be knocked out of the sky using sound waves alone. The vulnerability – resonance. Taking a drone and creating a sound that matches the natural resonant frequency of its gyroscope, resulting in erroneous flight outputs. Gyroscopes are typically designed to have resonant frequencies above the audible spectrum, but some models are still in the audible spectrum which makes them vulnerable to intentional interfering sound.

Submission + - Chinese to set up 'online security teams' at major internet firms->

An anonymous reader writes: China is planning to tighten its control over the country’s internet users with a new framework of security offices positioned in leading domestic tech firms and websites, the Chinese ministry of public security announced yesterday. With the growth in cloud and internet services China has wanted to gain more control over web usage, issuing warnings to popular social media sites owned by giants Tencent and Sina for the inadequate regulation of pornography and politically sensitive content. The government hopes that this move will help support surveillance and monitor for illegal online activity. He stressed that the new ‘online police’ would help websites refrain from publicising sensitive events and potentially vulgar content, which could lead to crime.

Submission + - Probe into Fukushima No.2 reactor hits snag

AmiMoJo writes: Sources familiar with the decommissioning process at the Fukushima Daiichi nuclear plant say efforts to determine the state of molten fuel in the reactors have hit another snag. Two new devices developed at a cost of more than 4 million dollars to take X-ray-like photos inside the No.2 reactor are too big to install. TEPCO devised the machines so that they use elementary particles called muons to see through hard surfaces and map the spread of fuel inside, but found the 8-by-8-meter devices will not fit the No.2 reactor building site unless they remove and decontaminate other equipment first. They believe that would hinder the decommissioning process and cost twice as much money as they spent creating the devices.

Submission + - Idaho Law Against Recording Abuses on Factory Farms Ruled Unconstitutional

onproton writes: An Idaho law that made it illegal to record and document animal abuse or dangerous hygienic practices in agricultural facilities, often referred to as an ‘ag-gag’ law, was ruled unconstitutional by a federal judge on Monday. The judge concluded that the law restricted constitutionally protected free speech, and contradicted “long-established defamation and whistleblowing statutes by punishing employees for publishing true and accurate recordings on matters of public concern.” Idaho is just one of several states to pass this type of law, which allow food production facilities to censor some unfavorable forms of speech at their convenience. Under the Idaho statute, an employee that witnessed and recorded an incident, even if it depicted true and life-threatening health or safety violations, could be faced with a year in jail and fines of up to “twice the economic loss the owner suffers.” In his ruling, the judge stated that this was “precisely the type of speech the First Amendment was designed to protect.” This decision has raised questions about the constitutionality of these types of laws in other states as well, and it’s likely that there will be more legal battles ahead.

Submission + - Sounds can knock drones out of the sky-> 1

angry tapir writes: Knocking a drone out of the sky is sometimes possible using an invisible weapon — sound. Researchers at the Korea Advanced Institute of Science and Technology (KAIST) in Daejon, South Korea, analyzed the effects of resonance on a crucial component of a drone, its gyroscope.

Submission + - MIT develops Biochemical sensor for cancer treatment

An anonymous reader writes: Researchers at MIT have developed a tiny biochemical sensor that can be implanted in cancerous tissue during the initial biopsy. The sensor then wirelessly sends data about telltale biomarkers to an external “reader” device, allowing doctors to better monitor a patient’s progress and adjust dosages or switch therapies accordingly. The sensors provide real-time, on-demand data concerning two biomarkers linked to a tumor’s response to treatment: pH and dissolved oxygen. The sensor housing[paper], made of a biocompatible plastic, is small enough to fit into the tip of a biopsy needle. It contains 10 microliters of chemical contrast agents typically used for magnetic resonance imaging (MRI) and an on-board circuit to communicate with the external reader device.

Submission + - Drone drops drugs onto Ohio prison yard->

Okian Warrior writes: Officers rushed into the north yard of Mansfield Correctional Institution in Mansfield, Ohio, last week after noticing 75 inmates gathering and a fight breaking out.

It wasn't until authorities later reviewed surveillance tape that they saw what led to the fisticuffs: A drone had flown over the yard and delivered 144.5 grams of tobacco, 65.4 grams of marijuana and 6.6 grams of heroin before the fight ensued.

If the heroin is half pure, that package amounts to about 140 individual doses,

Submission + - Swincar Tilting 4WD "Spider Car" Makes Light Work of Bizarre Terrain->

Zothecula writes: The Swincar Spider is a remarkable tilting 4-wheeler concept that boasts absolutely ridiculous rough terrain capabilities. Each wheel has its own electric hub motor and is independently suspended on a spider-like limb. The result is a vehicle that leans into fast turns like a motorcycle, but can also happily go up or down a 70-percent gradient, ride across a 50-percent gradient that puts the left wheels a couple of feet higher than the right ones, or ride diagonally through ditches that send the wheels going up and down all over the place like a spider doing leg stretches.

Submission + - Behold the whalecopter: Drones give whales a breathalyzer test ->

sciencehabit writes: Whales, like many cetaceans, are prone to respiratory tract infections, which can jeopardize already endangered populations. Assessing whales’ health, however, isn’t easy: Scientists hoping to measure bacteria and fungi in a whale’s “breath”—the moist air it shoots from its blowhole—need to get close enough to take a sample. Enter the whalecopter, a small, remote-controlled drone developed by researchers at the Woods Hole Oceanographic Institution in Massachusetts and the National Oceanic and Atmospheric Administration. The drone—a six-propeller hexacopter—can both collect breath samples and take high-resolution photos of the whales from the air to assess general health and conditions such as fat level and skin lesions. In a test at the Stellwagen Bank National Marine Sanctuary last month, the whalecopter first hovered about 40 meters above 36 whales to take full-body photographs of the animals—and then zoomed in to just a few meters above sea level to fly through the whales’ spouts and collect breath samples.

Submission + - USC vs. UC San Diego in Throwdown over Alzheimer's Research

BVBigelow writes: In Southern California, a legal skirmish between USC and UC San Diego is escalating into into a full-blown donnybrook, replete with restraining orders, loyalty oaths, and accusations of computer piracy, intimidation, and interference in federal grant awards. The two universities are fighting over control of an Alzheimer’s program that coordinates about $100 million in research grants. The lawsuits began after USC recruited scientist Paul Aisen from UC San Diego, where he has been director of the Alzheimer’s Disease Cooperative Study since 2007. The study has been based at UC San Diego since 1991, and and UCSD expected to retain control. But Aisen’s team took root command of the computer system (including 24 years’ worth of clinical trial data) and won’t give it back.

Submission + - FAA has approved more than 1,000 drone exemptions->

coondoggie writes: The Federal Aviation Administration today said it has issued 1,008 exemptions to businesses wanting to fly unmanned aircraft in the national airspace. Such small drones have been on the bad side of the news in the past few days as there have been at least 3 complaints about the diminutive aircraft flying near the flight path of JFK airport in New York. All three of the flights landed safely but the events prompted New York Senator Charles Schumer to call for called for “tougher FAA rules on drones, as well as geofencing software that could prohibit a done to fly higher than 500 feet, and keep it two miles away from any airport or sensitive area.

Submission + - Hackers Exploit Adobe Flash Vulnerability in Yahoo Ads

vivaoporto writes: According to the report in the New York Times Bits blog, for seven days, hackers used Yahoo’s ad network to send malicious bits of code to computers that visit Yahoo’s collection of heavily trafficked websites.

The attack, which started on July 28, was the latest in a string that have exploited Internet advertising networks, which are designed to reach millions of people online. It also highlighted growing anxiety over a much-used graphics program called Adobe Flash, which has a history of security issues that have irked developers at Silicon Valley companies.

“Right now, the bad guys are really enjoying this,” said Jérôme Segura, a security researcher at Malwarebytes, the security company that uncovered the attack. “Flash for them was a godsend.”

While Yahoo acknowledged the attack, the company said that it was not nearly as big as Malwarebytes had portrayed it to be.

“We take all potential security threats seriously,” a Yahoo spokeswoman said in statement. “With that said, the scale of the attack was grossly misrepresented in initial media reports, and we continue to investigate the issue.”

“In terms of how many people were served a malicious ad, only Yahoo would really know,” Mr. Segura said. But he added: “This is one of the largest attacks we’ve seen in recent months.”

Neither company could say exactly how many people were affected. After news of the attack was revealed, Adobe asked users to update Flash so their computers would no longer be vulnerable.
