Scientists at the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University have discovered how graphene — a single layer of carbon atoms with great promise for future electronics — is superconducting in a graphene-calcium compound, meaning that graphene would carry electricity with 100 percent efficiency.
While it’s been known for nearly a decade that this combined material is superconducting, the new study offers the first… read more

Remember the telephone game where people take turns whispering a message into the ear of the next person in line? By the time the last person speaks it out loud, the message has radically changed. It’s been altered with each retelling.
Every time you remember an event from the… read more

Experts from the Johns Hopkins Center for Sleep hope to help patients get a better night’s sleep by providing health care staff members with a basic educational tool on their smartphones.
Called MySleep101, the mobile learning application offers providers who are not experts in sleep disorders information on how to screen and counsel patients experiencing sleepless nights. Doctors, nurses and other care providers can access basic information about the seven… read more
Google announced today (May 15) that it test a few of its new Volkswagen Beetle-like prototype self-driving vehicles on roads in Mountain View, Calif. this summer Unlike Google’s previous prototype test vehicles, these will have safety drivers aboard, and with a steering wheel, accelerator pedal, and brake pedal if needed.
These vehicles are designed for local driving, with speed capped at 25mph.
Google said the… read more

A new study has found quantifiable evidence that supports the common-sense idea that walking in nature could lower your risk of depression.
The study, published in Proceedings of the National Academy of Science, found that people who walked for 90 minutes in a natural area, as opposed to participants who walked in a high-traffic urban setting (El Camino Real in Palo Alto, California, a noisy street with three to four… read more
Prototype software can give early warnings of disease or violence outbreaks by spotting clues in news reports.
Researchers have created software that predicts when and where disease outbreaks might occur, based on two decades of New York Times articles and other online data. The research comes from Microsoft and the Technion-Israel Institute of Technology, MIT Technology Review reports.
The system could someday help aid organizations and… read more

Two announcements yesterday (April 21) suggest that deep learning algorithms rival human skills in detecting cancer from ultrasound images and in identifying cancer in pathology reports.
Samsung Medison, a global medical equipment company and an affiliate of Samsung Electronics, has just updated its RS80A ultrasound imaging system with a deep learning algorithm for breast-lesion analysis.
The “S-Detect for Breast” feature uses big data collected… read more

Japanese scientists have used induced stem cells to create a liver-like tissue in a dish.
The achievement could have big clinical implications — a significant advance in the ability to coax stem cells to self-organize into organs.
The work was presented by Yokohama City University stem-cell biologist Takanori Takebe at the annual meeting of the International Society for Stem Cell Research in Yokohama.
“It blew my… read more
Large-scale wave energy systems developed in the Pacific Northwest should be comparatively steady, dependable, and able to be integrated into the overall energy grid at lower costs than some other forms of alternative energy, including wind power, a new analysis suggests.
The findings, published in the journal Renewable Energy, confirm what scientists have expected — that wave energy will have fewer problems with variability than some energy sources and… read more

Instead a carrying spare parts, space-constrained U.S. Navy ships in the future might carry 3-D printers and bags of various powdered ingredients, and simply download the design files needed to print items as necessary, according to the Armed Forces Journal,
“Perhaps closer at hand is a distributed global production network in which sailors and Marines send an email with a digital scan or design for a

University of Illinois at Urbana-Champaign and Northwestern University researchers have devised a novel nuclear magnetic resonance imaging (MRI) technique that delivers about 10 nanometers spatial resolution.
This represents a significant advance in MRI sensitivity. Current MRI techniques commonly used in medical imaging yield spatial resolutions on the millimeter length scale, with the highest-resolution experimental instruments giving spatial resolution of a few micrometers.
“Our approach… read more
