CWRU engineering researchers report nanoscale energy-efficient switching devices at IEDM 2013
Case Western Reserve University researchers have built nanoscale electromechanical switches and logic gates that operate more energy-efficiently than those now used by the billions in computers, tablets and smart phones. The switches are fast and light and have proved durable and heat tolerant, with no current leakage.

Scientists scale terahertz peaks in nanotubes
Rice scientists find plasmons at the root of a terahertz peak seen in carbon nanotubes, but only in certain types. The discovery opens up the possibility of using nanotubes in terahertz-based optoelectronics.

Researchers develop system for assessing how effective species are at pollinating crops
From tomatoes to pumpkins, most fruit and vegetable crops rely on pollination by bees and other insect species -- and the future of many of those species is uncertain. Now researchers from North Carolina State University are proposing a set of guidelines for assessing the performance of pollinator species in order to determine which species are most important and should be prioritized for protection.

Prolonged viewing of Boston Marathon bombings media coverage tied to acute stress
Stepping away from the television, computer screen or smartphone in the aftermath of terrorist attacks or mass shootings may be beneficial to your mental health. A new study by UC Irvine researchers shows that six or more daily hours of exposure to coverage of the Boston Marathon bombings in the week afterward was linked to more acute stress than having been at the event. Acute stress symptoms increased with each additional hour of media exposure.

Quality of biodiversity, not just quantity, is key
A new study of biodiversity loss in a salt marsh finds that it's not just the total number of species preserved that matters; it's the number of key species. If humans want to reap the benefits of the full range of functions that salt marshes and other coastal ecosystems provide, we need to preserve the right mix of species.

Astronomers discover planet that shouldn't be there
An international team of astronomers, led by a University of Arizona graduate student, has discovered the most distantly orbiting planet found to date around a single, sun-like star. Weighing in at 11 times Jupiter's mass and orbiting its star at 650 times the average Earth-Sun distance, planet HD 106906 b is unlike anything in our own Solar System and defies current planet formation theories.

New Jersey Shore likely faces unprecedented flooding by mid-century

Carnegie Mellon researchers create brand associations by mining millions of images from social media
The images people share on social media -- photos of favorite products and places, or of themselves at bars, sporting events and weddings -- could be valuable to marketers assessing their customers' "top-of-mind" attitudes toward a brand. Carnegie Mellon University researchers have taken a first step toward this capability in a new study in which they analyzed five million such images.

New finding shows that mother sharks 'home' to their birthplace to give birth, like salmon and sea turtles
Research conducted in Bimini in The Bahamas spanning almost two decades shows that female lemon sharks that were born there returned 15 years later to give birth to their own young, confirming this behavior for the first time in sharks. The study began in 1995, and has resulted in the capture, tagging, and release of more than 2,000 baby sharks over the 19-year, ongoing project.

Scientists calculate friction of Japan's 9.0 earthquake in 2011
An international team of scientists that installed a borehole temperature observatory following the 2011 Tohoku-Oki earthquake in Japan has been able to measure the "frictional heat" generated during the rupture of the fault -- an amount the researchers say was smaller than expected, which means the fault is more slippery than previously thought.

How mosquitoes are drawn to human skin and breath
Scientists at the University of California, Riverside have found that the very receptors in the mosquito's maxillary palp that detect carbon dioxide are ones that detect skin odors as well, thus explaining why mosquitoes are attracted to skin odor -- smelly socks, worn clothes, bedding -- even in the absence of carbon dioxide. Using a chemical computational method they developed, the researchers identified affordable, safe and pleasant-smelling compounds that could find use in mosquito control.

Rising ocean acidification leads to anxiety in fish
A new research study combining marine physiology, neuroscience, pharmacology, and behavioral psychology has revealed a surprising outcome from increases of carbon dioxide uptake in the oceans: anxious fish. Scientists at Scripps Institution of Oceanography at UC San Diego and MacEwan University in Edmonton, Canada, have shown for the first time that rising acidity levels increase anxiety in juvenile rockfish, an important commercial species in California.

Successful repair of bone defects using a novel tissue engineered bone graft
In this study, we engineered a novel biomimetic tissue engineered bone graft with MSCs isolated from rabbit adipose, using collagen I hydrogel to encapsulate the β-TCP scaffolds designed to enlarge the cells adhesion. The results demonstrated that the rabbit critical-sized bone defect could be completely repaired by the novel construct.

Carnegie Mellon scheme uses shared visual cues to help people remember multiple passwords
It turns out that the way to keep track of your many passwords to online accounts is the same as how to get to Carnegie Hall -- practice, practice, practice. So researchers at Carnegie Mellon University have devised a scheme that enables users to create 100 or more passwords by remembering -- and regularly rehearsing -- a small number of one-sentence stories. The story sentences become the basis for password fragments that are randomly combined to create unique, strong passwords for multiple accounts.
