Researchers Create Plant-Circuit Hybrid

sciencehabit writes: Researchers have crafted flexible electronic circuits inside a rose. Eventually such circuitry may help farmers eavesdrop on their crops and even control when they ripen. The advance may even allow people to harness energy from trees and shrubs not by cutting them down and using them for fuel, but by plugging directly into their photosynthesis machinery. The researchers used “an organic electronic building block called PEDOT-S:H. Each of these building blocks consists of a short, repeating chain of a conductive organic molecule with short arms coming off each link of the chain. Each of the arms sports a sulfur-containing group linked to a hydrogen atom. Berggren’s group found that when they placed them in the water, the rose stems readily pulled the short polymer chains up the xylem channels (abstract). … The upshot was that the myriad short polymer chains quickly linked themselves together into continuous strings as long as 10 centimeters. The researchers then added electronic probes to opposite ends of these strings, and found that they were, in fact, wires, conducting electricity all down the line.” Read more of this story at Slashdot.

First Images Ever Taken of a Planet Being Formed, 450 Light-Years From Earth

Zothecula writes: Of the many new exoplanets discovered over the past two decades, all have been identified as established, older planets – none have been acknowledged as newly-forming protoplanets. Now scientists working at the Keck observatory have spied just such a planet in the constellation of Taurus, some 450 light-years from Earth (abstract), that is only just beginning its life, collecting matter and spinning into a brand new world.

First Liquid-Cooling Laser Could Advance Biological Research

Zothecula writes: In a world where lasers are sci-fi’s weapon of choice for melting away an enemy spaceship, researchers at the University of Washington have swum against the current and produced the first laser capable of cooling liquids. ” They demonstrated that the laser could refrigerate saline solution and cell culture media that are commonly used in genetic and molecular research. To achieve the breakthrough, the UW team used a material commonly found in commercial lasers but essentially ran the laser phenomenon in reverse. They illuminated a single microscopic crystal suspended in water with infrared laser light to excite a unique kind of glow that has slightly more energy than that amount of light absorbed. This higher-energy glow carries heat away from both the crystal and the water surrounding it.” The technology could be especially useful for slowing down single cells and allowing scientists to study biological processes as they happen.

The Next Gold Rush Will Be 5,000 Feet Under the Sea, With Robot Drones

merbs writes: In Papua New Guinea, one well-financed, first-mover company is about to pioneer deep sea mining. And that will mean dispatching a fleet of giant remote-operated robotic miners 5, 000 feet below the surface to harvest the riches scattered across ocean floor. These mammoth underwater vehicles look like they’ve been hauled off the set of a sci-fi film—think Avatar meets The Abyss. And they’ll be dredging up copper, gold, and other valuable minerals, far beneath the gaze of human eyes. Read more of this story at Slashdot.

Intel Flagship Core I7-6950X Broadwell-E To Offer 10-Cores, 20-Threads, 25MB L3

MojoKid writes: Intel has made a habit of launching enthusiast versions of previous generations processors after it releases it a new architecture. As was the case with Intel’s Haswell architecture, high-end Broadwell-E variants are expected and a it looks like Intel is readying a doozy. Recent details revealed show four new processors under the new HEDT (High-End Desktop) banner for Broadwell, which is one more SKU than Haswell-E brought to the table. The most intriguing of the new chips is the Core i7-6950X, a monster 10-core CPU with Hyper Threading support. That gives the Core i7-6950X 20 threads to play with, along with a whopping 25MB of L3 cache. The caveat is the CPU’s clockspeed — it will run at just 3.0GHz (base), so for applications that aren’t properly tuned to take full advantage of large core counts and threads, it could potentially trail behind the Core i7-6700K, a quad-core Skylake processor clocked at 3.4GHz (base) to 4GHz (Turbo).

Police Body Cameras Come With Pre-Installed Malware

An anonymous reader writes: The old Conficker worm was found on new police body cameras that were taken out of the box by security researchers from iPower Technologies. The worm is detected by almost all security vendors, but it seems that it is still being used because modern day IoT devices can’t yet run security products. This allows the worm to spread, and propagate to computers when connected to an unprotected workstation. One police computer is enough to allow attackers to steal government data. The source of the infection is yet unknown. It is highly unlikely that the manufacturer would do this. Middleman involved in the shipping are probably the cause. Read more of this story at Slashdot.

Dubai Buys Commercial Jetpacks For Firefighters

_Sharp’r_ writes: Want to fly a jetpack? Join the fire department in Dubai. In a skyscraper filled city where cops drive Ferraris and Lamborghinis, it was actually cheaper to buy twenty $150K jetpacks (plus two simulators) for fire rescue rather than find 2700 ft ladders. Slashdot has had stories about these coming for five years. A VR-headset based jetpack flight-simulator for the masses would be fun, too, even better if the object were to put out fires in skyscrapers.. Read more of this story at Slashdot.

Windows 3.1 Glitch Causes Problems At French Airport — Wait, 3.1?

OakDragon writes: Microsoft has tamped down the earth on XP’s grave, steered Internet Explorer toward the nursing home, and is trying to convince everyone Windows 10 is a bright up-and-comer. But in the Paris airport of Orly, a system called DECOR — which helps air traffic controllers relay weather information to pilots — is running on Windows 3.1. That program suffered a glitch recently that grounded planes for some time. The airport actually runs on a variety of old systems, including Windows XP and UNIX. Maintenance is a problem. There are only three people in Paris that work on DECOR issues, and one of them is retiring soon. Hardware is also an issue. “Sometimes we have to go rummaging on eBay to replace certain parts, ” said Fiacre. “In any case, these machines were not designed to keep working for more than 20 years.” Read more of this story at Slashdot.

Quantum Dots Made From Fool’s Gold Boost Battery Performance

Science_afficionado writes: A lot of attempts have been made to use nanocrystals to improve battery performance, but the results have been disappointing. The problem is that when the size of the crystals drop below a certain size they begin to react chemically with the electrolytes which prevents them from recharging. Now, however, a team of engineers from Vanderbilt University report in an article published in the journal ACS Nano that they can overcome this problem by making the nanocrystals out of iron pyrite, commonly known as fool’s gold.
