Deep Learning despite sparse data

DFG research group focuses on evaluation of chemical process data

29-Jul-2022 - The German Research Foundation (DFG) is funding the new research group "Deep Learning on sparse chemical process data" for four years with around 3.5 million euros. It is coordinated at the Technical University of Kaiserslautern (TUK). The group is working on making Deep Learning methods, a ...

Bacteria self-organize to build working sensors

12-Oct-2017 - Researchers at Duke University have turned bacteria into the builders of useful devices by programming them with a synthetic gene circuit. As a bacterial colony grows into the shape of a hemisphere, the gene circuit triggers the production of a type of protein to distribute within the colony that ...

Watching 'artificial atoms' assemble into perfect lattices

Scientists see numerous uses

02-Aug-2017 - Some of the world's tiniest crystals are known as "artificial atoms" because they can organize themselves into structures that look like molecules, including "superlattices" that are potential building blocks for novel materials. Now scientists from the Department of Energy's SLAC National ...

When gold turns invisible

Application in bioimaging and security inks possible

02-Jun-2017 - A gold compound shifts from a visible fluorescence to emitting infrared when ground - a big shift with potential applications in bioimaging and security inks. Some materials luminesce, changing their color and intensity when under mechanical forces such as grinding or rubbing. These luminescent ...

In Flow State

03-Mar-2017 - Ever wonder why you have to shake your bottle of ketchup or mustard before pouring? Or why, to get out of quicksand, you must move slowly? Or why you can run on the surface of a suspension of cornstarch in water, but you’d sink if you tried to walk on it? The common feature of all these ...

New sensors can detect single protein molecules

Modified carbon nanotubes could be used to track protein production by individual cells.

25-Jan-2017 - For the first time, MIT engineers have designed sensors that can detect single protein molecules as they are secreted by cells or even a single cell. These sensors, which consist of chemically modified carbon nanotubes, could help scientists with any application that requires detecting very small ...

DNA nanotubes build a bridge between 2 molecular posts

09-Jan-2017 - In a microscopic feat that resembled a high-wire circus act, Johns Hopkins researchers have coaxed DNA nanotubes to assemble themselves into bridge-like structures arched between two molecular landmarks on the surface of a lab dish. The team captured examples of this unusual nanoscale performance ...

New technology taps power of diatoms to dramatically improve sensor performance

11-Nov-2016 - Researchers at Oregon State University have combined one of nature's tiny miracles, the diatom, with a version of inkjet printing and optical sensing to create an exceptional sensing device that may be up to 10 million times more sensitive than some other commonly used approaches. A patent has ...

Nanobionic spinach plants can detect explosives

After sensing dangerous chemicals, the carbon-nanotube-enhanced plants send an alert.

01-Nov-2016 - Spinach is no longer just a superfood: By embedding leaves with carbon nanotubes, MIT engineers have transformed spinach plants into sensors that can detect explosives and wirelessly relay that information to a handheld device similar to a smartphone. This is one of the first demonstrations of ...

Veggie juice that illuminates the gut

13-Jul-2016 - The pigment that gives spinach and other plants their verdant color may improve doctors' ability to examine the human gastrointestinal tract. That's according to a study which describes how chlorophyll-based nanoparticles suspended in liquid are an effective imaging agent for the gut. "Our work ...
