Smaller lidars could allow UAVs to conduct underwater scans

December 4, 2014 8:06 am | by Rick Robinson, Georgia Institute of Technology | News | Comments

Bathymetric lidars are used today primarily to map coastal waters. At nearly 600 lbs, the systems are large and heavy, and they require costly, piloted aircraft to carry them. A team at the Georgia Tech Research Institute has designed a new approach that could lead to bathymetric lidars that are much smaller and more efficient than the current full-size systems.

“Mirage Earth” exoplanets may have burned away chances for life

December 3, 2014 11:21 am | by Peter Kelley, News and Information, Univ. of Washington | News | Comments

Planets orbiting close to low-mass stars are prime targets in the search for extraterrestrial life. But new research led by an astronomy graduate student at the Univ. of Washington indicates some such planets may have long since lost their chance at hosting life because of intense heat during their formative years.

Technique simultaneously determines nanomaterials’ chemical makeup

December 3, 2014 8:47 am | by Angela Hardin, Argonne National Laboratory | News | Comments

A team of researchers from Argonne National Laboratory and Ohio Univ. have devised a powerful technique that simultaneously resolves the chemical characterization and topography of nanoscale materials down to the height of a single atom. The technique combines synchrotron x-rays (SX) and scanning tunneling microscopy (STM). In experiments, the researchers used SX as a probe and a nanofabricated smart tip of a STM as a detector.

Computer model enables design of complex DNA shapes

December 3, 2014 8:31 am | by Anne Trafton, MIT News Office | Videos | Comments

Biological engineers have created a new computer model that allows them to design the most complex 3-D DNA shapes ever produced, including rings, bowls and geometric structures such as icosahedrons that resemble viral particles. This design program could allow researchers to build DNA scaffolds to anchor arrays of proteins and light-sensitive molecules called chromophores that mimic the photosynthetic proteins found in plant cells.

In 1997, IBM’s Deep Blue computer beat chess wizard Garry Kasparov. This year, a computer system developed at the Univ. of Wisconsin-Madison equaled or bested scientists at the complex task of extracting data from scientific publications and placing it in a database that catalogs the results of tens of thousands of individual studies.

Engineers make sound loud enough to bend light on a computer chip

December 1, 2014 10:08 am | by Univ. of Minnesota | News | Comments

During a thunderstorm, we all know it’s common to hear thunder after we see the lightning. That’s because sound travels much slower (768 mph) than light (670,000,000 mph). Now, Univ. of Minnesota engineering researchers have developed a chip on which both sound wave and light wave are generated and confined together so that the sound can very efficiently control the light.

Sustainable BIM

December 1, 2014 9:52 am | by Lindsay Hock, Managing Editor | Articles | Comments

Building information modeling (BIM), now a standard tool throughout most architecture sectors, is critical for complex building types like healthcare and lab projects. Clients are finding great use for these models in facilities maintenance and long-term campus facilities planning. Owners also see great benefit with BIM, as many are interested in the long-term maintenance and scheduling abilities it offers.

Blu-ray disc can be used to improve solar cell performance

November 25, 2014 8:23 pm | by Northwestern Univ. | News | Comments

Who knew Blu-ray discs were so useful? Already one of the best ways to store high-definition movies and television shows because of their high-density data storage, Blu-ray discs also improve the performance of solar cells, according to new research from Northwestern Univ.

Environmental “tipping points” key to predicting extinctions

November 25, 2014 11:35 am | by Tracey Peake, North Carolina State Univ. | News | Comments

Researchers from North Carolina State Univ. have created a model that mimics how differently adapted populations may respond to rapid climate change. Their findings demonstrate that depending on a population’s adaptive strategy, even tiny changes in climate variability can create a “tipping point” that sends the population into extinction.
