California drought linked to climate change

September 30, 2014 9:42 am | by Ker Than, Stanford Univ. | Comments

The atmospheric conditions associated with the unprecedented drought currently afflicting California are "very likely" linked to human-caused climate change, according to Stanford Univ. scientists. The team used a combination of computer simulations and statistical techniques to show that a persistent region of high atmospheric pressure hovering over the Pacific Ocean was likely to form from modern greenhouse gas concentrations.

Scientists make droplets move on their own

September 29, 2014 12:51 pm | Comments

Droplets are simple spheres of fluid, not normally considered capable of doing anything on their own. But now researchers have made droplets of alcohol move through water, even moving through complex mazes. The droplets can be led to certain targets, using a surprisingly simple impetus. In the future, such moving droplets may deliver medicines, moving entire chemistries to targets.

Magnetic field opens and closes nanovesicle

September 24, 2014 9:18 am | Comments

Researchers in the Netherlands have managed to open nanovesicles in a reversible process and close them using a magnet. Previously, these vesicles had been “loaded” with a drug and opened elsewhere using a chemical process, such as osmosis. The magnetic method, which is repeatable, is the first to demonstrate the viability of another method.

Nanotubes help healing hearts keep the beat

September 23, 2014 2:58 pm | Comments

A Rice Univ. team led by bioengineer Jeffrey Jacot and chemical engineer and chemist Matteo Pasquali have created new pediatric heart-defect patches infused with conductive single-walled carbon nanotubes that allow electrical signals to pass unhindered. The nanotubes overcome a limitation of current patches in which pore walls hinder the transfer of electrical signals between cardiomyocytes, the heart muscle’s beating cells.

Smallest possible “diamonds” help form ultra-thin nanothreads

September 22, 2014 2:52 pm | Comments

For the first time, scientists led by John V. Badding, a professor of chemistry at Penn State Univ., have discovered how to produce ultra-thin "diamond nanothreads" that promise extraordinary properties, including strength and stiffness greater than that of today's strongest nanotubes and polymers. The core of the nanothreads is a long, thin strand of carbon atoms arranged just like the fundamental unit of a diamond's structure.

Startup scales up graphene production, develops biosensors and supercapacitors

September 19, 2014 10:59 am | Comments

Glenn Johnson, CEO of BlueVine Graphene Industries Inc., said many of the methodologies being utilized to produce graphene today are not easily scalable and require numerous post-processing steps to use it in functional applications. He said his company has developed a way to scale graphene production using a roll-to-roll chemical vapor deposition process.

A new way to prevent the spread of devastating diseases

September 19, 2014 8:01 am | by Kimm Fesenmaier, Caltech | Comments

For decades, researchers have tried to develop broadly effective vaccines to prevent the spread of illnesses such as HIV, malaria and tuberculosis. While limited progress has been made along these lines, there are still no licensed vaccinations available that can protect most people from these devastating diseases. So what are immunologists to do when vaccines just aren't working?

Scientists refine formula for nanotube types

September 17, 2014 9:52 am | by Mike Williams, Rice Univ. | Comments

Many a great idea springs from talks over a cup of coffee. But it’s rare and wonderful when a revelation comes from the cup itself. Rice Univ. theoretical physicist Boris Yakobson, acting upon sudden inspiration at a meeting last year, obtained a couple of spare coffee cups from a server and a pair of scissors and proceeded to lay out—science fair-style—an idea that could have far-reaching implications for the nanotechnology industry.

Researchers control surface tension to manipulate liquid metals

September 16, 2014 9:40 am | by Matt Shipman, News Services, North Carolina State Univ. | Comments

Researchers from North Carolina State Univ. have developed a technique for controlling the surface tension of liquid metals by applying very low voltages, opening the door to a new generation of reconfigurable electronic circuits, antennas and other technologies. The technique hinges on the fact that the oxide “skin” of the metal acts as a surfactant, lowering the surface tension between the metal and the surrounding fluid.

Want to print your own cell phone microscope for pennies?

September 16, 2014 8:01 am | by Susan Bauer, PNNL | Comments

At one o'clock in the morning, layers of warm plastic are deposited on the platform of the 3-D printer that sits on scientist Rebecca Erikson's desk. A small plastic housing, designed to fit over the end of a cell phone, begins to take shape. Pulling it from the printer, Erikson quickly pops in a tiny glass bead and checks the magnification.

Bound for robotic glory

September 16, 2014 7:56 am | by Jennifer Chu, MIT News Office | Comments

The fastest land animal on Earth, the cheetah, is able to accelerate to 60 mph in just a few seconds. As it ramps up to top speed, a cheetah pumps its legs in tandem, bounding until it reaches a full gallop. Now, researchers have developed an algorithm for bounding that they’ve successfully implemented in a fully functional robotic cheetah.

Moving silicon atoms in graphene with atomic precision

September 15, 2014 10:34 am | Comments

In recent years, it has become possible to see directly individual atoms using electron microscopy, especially in graphene. Using electron microscopy and computer simulations, an international team has recently shown how an electron beam can move silicon atoms through the graphene lattice without causing damage.

Study sheds new light on why batteries go bad

September 15, 2014 7:34 am | by Andrew Gordon, SLAC National Accelerator Laboratory | Comments

A comprehensive look at how tiny particles in a lithium-ion battery electrode behave shows that rapid-charging the battery and using it to do high-power, rapidly draining work may not be as damaging as researchers had thought—and that the benefits of slow draining and charging may have been overestimated.

Faster image processing for low-radiation CT scans

September 12, 2014 8:08 am | by Kate McAlpine, Univ. of Michigan | Comments

A new $1.9 million study at the Univ. of Michigan seeks to make low-dose computed tomography scans a viable screening technique by speeding up the image reconstruction from half an hour or more to just five minutes. The advance could be particularly important for fighting lung cancers, as symptoms often appear too late for effective treatment.

World’s first 3-D printed car being assembled at IMTS

September 10, 2014 6:15 pm | Comments

During the six-day IMTS manufacturing technology show in Chicago this week, the “Strati” will be the first vehicle printed in one piece using direct digital manufacturing. The process will take more than 44 hours of print time. A team including Local Motors, Cincinnati Inc. and Oak Ridge National Laboratory will then rapidly assemble it for a historic first set for Saturday.
