R&D Live: Has 3D Printing Become a Commodity OnDemand

June 1, 2015 | by Tim Studt | Videos | Comments

With all of the manufacturing and tooling capabilities, are 3D printers becoming a service-based commodity with all the reticent encumbrances associated with this connotation? Is the technology and its associated materials still advancing at a rapid pace? What are the different capabilities, limitations and applications of the current iterations of 3D printing equipment materials and technologies?

Backward-moving glacier helps scientists explain glacial earthquakes

June 26, 2015 7:21 am | by Jim Erickson, Univ. of Michigan Videos Comments

The relentless flow of a glacier may seem unstoppable, but a team of researchers has shown that during some calving events, the glacier moves rapidly backward and downward, causing the characteristic glacial earthquakes which until now have been poorly understood. This new insight into glacier behavior should enable scientists to measure glacier calving remotely.

Re-energizing antibiotics in the war against infections

June 24, 2015 5:00 pm | by Kat J. McAlpine, Wyss Institute for Biologically Inspired Engineering Videos Comments

Antibiotics are the mainstay in the treatment of bacterial infections, and together with vaccines, have enabled the near eradication of infectious diseases in developed countries. However, the overuse of antibiotics has also led to an alarming rise in resistant bacteria that can outsmart antibiotics using different mechanisms. Some pathogenic bacteria are thus becoming almost untreatable.

Single-catalyst water splitter produces clean-burning hydrogen 24/7

June 23, 2015 10:45 am | by Mark Shwartz, Stanford Univ. Videos Comments

Stanford Univ. scientists have invented a low-cost water splitter that uses a single catalyst to produce both hydrogen and oxygen gas 24 hrs a day, seven days a week. The device, described in Nature Communications, could provide a renewable source of clean-burning hydrogen fuel for transportation and industry.

Science Connect: GMOs Could be Nutritionally Valuable, If Not for Intense Regulations

June 23, 2015 7:47 am | by Michelle Taylor, Editor-in-Chief, Laboratory Equipment and Jon Dipierro, Multimedia Production Videos Comments

In this one-minute video, hear from Nina Fedoroff, the former Science and Technology advisor to U.S. Secretaries of State Condoleezza Rice and Hillary Clinton, on why she blames intense regulatory demands for the lack of nutritionally valuable GMOs.

New “molecular movie” reveals ultrafast chemistry in motion

June 22, 2015 11:15 am | by Andrew Gordon, SLAC National Accelerator Laboratory Videos Comments

Scientists, for the first time, tracked ultrafast structural changes, captured in quadrillionths-of-a-second steps, as ring-shaped gas molecules burst open and unraveled. Ring-shaped molecules are abundant in biochemistry and also form the basis for many drug compounds. The study points the way to a wide range of real-time x-ray studies of gas-based chemical reactions that are vital to biological processes.

Team fuses art, engineering to create stretchable batteries

June 22, 2015 10:10 am | by Joe Kullman, Arizona State Univ. Videos Comments

Origami, the centuries-old Japanese paper-folding art, has inspired recent designs for flexible energy-storage technology. But energy-storage device architecture based on origami patterns has so far been able to yield batteries that can change only from simple folded to unfolded positions. They can flex, but not actually stretch.

X-ray imaging reveals secrets in battery materials

June 19, 2015 8:47 am | by Liezel Labios, Univ. of California, San Diego Videos Comments

In a new study, researchers explain why one particular cathode material works well at high voltages, while most other cathodes do not. The insights, published in Science, could help battery developers design rechargeable lithium-ion batteries that operate at higher voltages.

Mantis shrimp inspires new body armor

June 18, 2015 8:15 am | by Sean Nealon, Univ. of California, Riverside Videos Comments

The mantis shrimp is able to repeatedly pummel the shells of prey using a hammer-like appendage that can withstand rapid-fire blows by neutralizing certain frequencies of “shear waves,” according to new research. The club is made of a composite material containing fibers of chitin, the same substance found in many marine crustacean shells and insect exoskeletons but arranged in a helicoidal structure that resembles a spiral staircase.

Nanorobots swim through blood to deliver drugs

June 18, 2015 7:39 am | by American Chemical Society Videos Comments

Someday, treating patients with nanorobots could become standard practice to deliver medicine specifically to parts of the body affected by disease. But merely injecting drug-loaded nanoparticles might not always be enough to get them where they need to go. Now scientists are reporting in Nano Letters the development of new nanoswimmers that can move easily through body fluids to their targets.

Battery uses light to produce power

June 17, 2015 9:10 am | by American Chemical Society Videos Comments

To move the world toward sustainability, scientists are continuing to explore and improve ways to tap the vast power of sunlight to make fuels and generate electricity. Now they have come up with a new way to use light—solar or artificial—to drive battery power safely. Their “photo battery,” reported in The Journal of Physical Chemistry C, uses light and titanium nitride for the anode.

New fog chamber provides testing that could improve security cameras

June 17, 2015 8:21 am | by Heather Clark, Sandia National Laboratories Videos Comments

Fog can play a key role in cloaking military invasions and retreats and the actions of intruders. That’s why physical security experts seek to overcome fog, but it’s difficult to field test security cameras, sensors or other equipment in fog that is often either too thick or too ephemeral. Until now, collecting field test data in foggy environments was time-consuming and costly.

Amplifying small motions in large motions

June 17, 2015 7:40 am | by Larry Hardesty, MIT News Office Videos Comments

For several years now, the research groups of Massachusetts Institute of Technology professors of computer science and engineering William Freeman and Frédo Durand have been investigating techniques for amplifying movements captured by video but indiscernible to the human eye. Versions of their algorithms can make the human pulse visible and even recover intelligible speech from the vibrations of objects filmed through soundproof glass.
