World speed record for polymer simulations shattered by over a hundred-fold



Posted: 14 Sep 2018 07:03 AM PDT


By analogy to linear polymers, which reptate with a random walk embedded in a 3D network, we show that star polymers relax by a random walk in a 5D network.


Programmable materials: Hydrogels capable of complex movement created



Posted: 13 Sep 2018 10:45 AM PDT


Researchers have developed a process by which 2-D hydrogels can be programmed to expand and shrink in a space- and time-controlled way that applies force to their surfaces, enabling the formation of complex 3-D shapes and motions.


Helping computers fill in the gaps between video frames



Posted: 13 Sep 2018 10:45 AM PDT


Researchers have developed an add-on module that helps artificial intelligence systems called convolutional neural networks, or CNNs, to fill in the gaps between video frames to greatly improve the network's activity recognition.


The next phase: Using neural networks to identify gas-phase molecules



Posted: 13 Sep 2018 08:39 AM PDT


Scientists have developed a neural network that can identify the structure of molecules in the gas phase, offering a novel technique for national security and pharmaceutical applications.


BPA replacements in plastics cause reproductive problems in lab mice



Posted: 13 Sep 2018 08:39 AM PDT


Twenty years ago, researchers made the accidental discovery that BPA had leached out of plastic cages used to house female mice in the lab, causing an increase in chromosomally abnormal eggs. Now, the same team is back to report that the array of alternative bisphenols now used to replace BPA in BPA-free bottles, cups, cages, and other items appear to come with similar problems for their mice.


Enhanced 3-D imaging poised to advance treatments for brain diseases



Posted: 13 Sep 2018 08:39 AM PDT


Researchers have developed a combination of commercially available hardware and open-source software, named PySight, which improves rapid 2-D and 3-D imaging of the brain and other tissues.


BUFFALO charges towards the earliest galaxies



Posted: 13 Sep 2018 08:39 AM PDT


The NASA/ESA Hubble Space Telescope has started a new mission to shed light on the evolution of the earliest galaxies in the Universe. The BUFFALO survey will observe six massive galaxy clusters and their surroundings. The first observations show the galaxy cluster Abell 370 and a host of magnified, gravitationally lensed galaxies around it.


Computer avatars play a part in dementia detection



Posted: 13 Sep 2018 08:38 AM PDT


Scientists have demonstrated the possibility of detecting dementia from conversations in human-agent interaction. Their research shows how a machine can learn characteristics of sounds of elderly people who answered easy questions from avatars on a computer.


New devices could reduce excess heat in computers



Posted: 13 Sep 2018 08:38 AM PDT


Antiferromagnets could make it possible to achieve computing speeds much faster than existing devices, new research suggests.


VLBA measures asteroid's characteristics



Posted: 13 Sep 2018 08:38 AM PDT


Astronomers took advantage of a celestial alignment to make a novel and creative radio observation yielding information about the size, shape, and orbit of an asteroid.


Laser sintering optimized for printed electronics



Posted: 13 Sep 2018 08:38 AM PDT


A new study provides insights into the processing of copper nanoparticle ink with green laser light.


Rural and urban communities need different policies to boost economic mobility



Posted: 12 Sep 2018 10:35 AM PDT


The farther away from a city a person is raised, the more likely they are to climb the economic ladder, according to economists, who also found that community characteristics associated with upward mobility actually have different effects in rural and urban locations.


Business genius can be taught, study says



Posted: 12 Sep 2018 10:35 AM PDT


How did Steve Jobs do it? What about Whole Foods Market and Starbucks? These kinds of 'breakout' success stories show what is possible when business leaders imagine into the future rather than re-enacting the past -- a strategy that a new study says is crucial for business success in a rapidly changing world.


Enhancing data analysis for large hadron collider



Posted: 12 Sep 2018 10:34 AM PDT


Physicists have created new techniques that deploy machine learning as a means to significantly improve data analysis for the Large Hadron Collider (LHC), the world's most powerful particle accelerator.


Fluorescence-activating beta-barrel protein made from scratch for first time



Posted: 12 Sep 2018 10:34 AM PDT


For the first time, scientists have created, entirely from scratch, a protein capable of binding to a small target molecule. They designed a cylindrical protein called a beta barrel, which has a cavity to bind the target. The designed protein was able to bind and activate a compound similar to that housed inside green fluorescent protein.


New sensors track dopamine in the brain for more than year



Posted: 12 Sep 2018 05:12 AM PDT


Neuroscientists have devised a way to measure dopamine in the brain for up to a year, which they believe will teach them much more about its role in key brain functions and in disorders such as depression and Parkinson's disease.
