Scientists Stored These Images in DNA—Then Flawlessly Retrieved Them

Posted by in category: biotech/medical

Who needs memory cards when you have DNA? A team of scientists has been able to store images within the life-defining molecules then retrieve them perfectly.

Researchers from the University of Washington have been working out how to take digital files and convert them into strings of DNA that can be easily read back. Luis Ceze, one of the researchers, explains in a press release:

“Life has produced this fantastic molecule called DNA that efficiently stores all kinds of information about your genes and how a living system works — it’s very, very compact and very durable. We’re essentially repurposing it to store digital data — pictures, videos, documents — in a manageable way for hundreds or thousands of years.”

Dressed to kill: Tailoring a suit for tumor-penetrating cancer meds

Posted by in categories: biotech/medical, engineering, health, particle physics

Very cool.


For more than a decade, biomedical researchers have been looking for better ways to deliver cancer-killing medication directly to tumors in the body. Tiny capsules, called nanoparticles, are now being used to transport chemotherapy medicine through the bloodstream, to the doorstep of cancerous tumors. But figuring out the best way for the particles to get past the tumor’s “velvet rope” and enter the tumor is a challenge scientists are still working out. Drexel University researchers believe that the trick to gaining access to the pernicious cellular masses is to give the nanoparticles a new look—and that dressing to impress will be able to get them past the tumor’s biological bouncers.

Targeted cancer therapy is most effective when the medication is released as close as possible to the interior of a , to increase its odds of penetrating and killing off cancerous cells. The challenge that has faced cancer researchers for years is making a delivery vehicle that is sturdy enough to safely get the medication through the bloodstream to tumors—which is no smooth ride—but is also lithe enough to squeeze through the tumor’s dense extra cellular space—a matrix stuffed with sugars called hyaluronic acid.

High-Resolution, SWAXS Characterisation of Nanostructures and Nanomaterials with the SAXSpace

Posted by in categories: food, nanotechnology, particle physics

Nanostructured samples and materials can be efficiently and reliable characterized using Anton Paar’s SAXSpace small- and wide-angle X-ray scattering (SWAXS) system. Users can obtain the size, shape, and size distribution of nano-sized samples and particle domains with the help of the SAXSpace. The device is ideally suited for the analysis of colloidal, biological (Bio-SAXS), and isotropic samples.

The SWAXS system also has a wide selection of accurate and versatile sample stages to meet each SAXS application. Easy handling and automatic alignment facilitate smooth operation. With the unique combination of robust design, short measurement time, and high system uptime, the device not only provides superior WAXS or SAXS results but also ensures high sample throughput. These capabilities make SAXSpace ideally suited to explore nanostructure in various materials, including surfactants, pharmaceuticals, proteins, foods, polymers, and nanoparticles.

‘Chatbots’ are coming; next stop Facebook

Posted by in category: robotics/AI

I expect to see more and more online consumers having their own “Personalized” bots that mimics them online. Granted at the moment we see the more generic versions of a personal assistant, etc. However, I do believe the next major push will be providing the consumers the flexibility of personalizing their bots that mimics them in their communication styles, interaction style, interests, personalities, etc.


SAN FRANCISCO — Will there be a bot for that?

Quantum dots enhance light-to-current conversion in layered metal dichalcogenide semiconductors

Posted by in categories: computing, electronics, quantum physics, solar power, sustainability

Improving light-sensing devices with Q-Dots.


Harnessing the power of the sun and creating light-harvesting or light-sensing devices requires a material that both absorbs light efficiently and converts the energy to highly mobile electrical current. Finding the ideal mix of properties in a single material is a challenge, so scientists have been experimenting with ways to combine different materials to create “hybrids” with enhanced features.

In two just-published papers, scientists from the U.S. Department of Energy’s Brookhaven National Laboratory, Stony Brook University, and the University of Nebraska describe one such approach that combines the excellent light-harvesting properties of quantum dots with the tunable electrical conductivity of a layered tin disulfide semiconductor. The hybrid material exhibited enhanced light-harvesting properties through the absorption of light by the quantum dots and their energy transfer to tin disulfide, both in laboratory tests and when incorporated into electronic devices. The research paves the way for using these materials in optoelectronic applications such as energy-harvesting photovoltaics, light sensors, and light emitting diodes (LEDs).
