Opening doors to foldable electronics with inkjet-printed graphene

Imagine a bendable tablet computer or an electronic newspaper that could fold to fit in a pocket.

The technology for these devices may not be so far off. Northwestern University researchers have recently developed a graphene-based ink that is highly conductive and tolerant to bending, and they have used it to inkjet-print graphene patterns that could be used for extremely detailed, conductive electrodes.

Researchers perform fastest measurements ever made of ion channel proteins

New York, NY—May 20, 2013—The miniaturization of electronics continues to create unprecedented capabilities in computer and communications applications, enabling handheld wireless devices with tremendous computing performance operating on battery power. This same miniaturization of electronic systems is also creating new opportunities in biotechnology and biophysics.

72 percent of pregnant women experience constipation and other bowel problems

MAYWOOD, Il. - Nearly three out of four pregnant women experience constipation, diarrhea or other bowel disorders during their pregnancies, a Loyola University Medical Center study has found.

But such bowel disorders have only minimal impacts on pregnant women's quality of life, the study found.

The study by senior author Scott Graziano, MD and Payton Johnson was presented during the American Congress of Obstetricians and Gynecologists 61st Annual Clinical Meeting in New Orleans.

Not just blowing in the wind: Compressing air for renewable energy storage

RICHLAND, Wash. – Enough Northwest wind energy to power about 85,000 homes each month could be stored in porous rocks deep underground for later use, according to a new, comprehensive study. Researchers at the Department of Energy's Pacific Northwest National Laboratory and Bonneville Power Administration identified two unique methods for this energy storage approach and two eastern Washington locations to put them into practice.

Food laboratory accuracy remains a concern

Food microbiology laboratories continue to submit false negative results and false positive results on a routine basis. A retrospective study of nearly 40,000 proficiency test results over the past 14 years, presented today at the 113th General Meeting of the American Society for Microbiology, examined the ability of food laboratories to detect or rule out the presence of Escherichia coli O157:H7, Salmonella, Listeria monocytogenes, and Campylobacter.

1 in 10 teens using 'study drugs,' but parents aren't paying attention

ANN ARBOR, Mich. – As high schoolers prepare for final exams, teens nationwide may be tempted to use a "study drug" -- a prescription stimulant or amphetamine -- to gain an academic edge. But a new University of Michigan poll shows only one in 100 parents of teens 13-17 years old believes that their teen has used a study drug.

Study drugs refer to stimulant medications typically prescribed for the treatment of attention deficit hyperactivity disorder (ADHD); commonly prescribed medicines in this category include Adderall, Concerta, Ritalin, and Vyvanse.

New study finds blind people have the potential to use their 'inner bat' to locate objects

New research from the University of Southampton has shown that blind and visually impaired people have the potential to use echolocation, similar to that used by bats and dolphins, to determine the location of an object.

Immune protein could stop diabetes in its tracks

Melbourne researchers have identified an immune protein that has the potential to stop or reverse the development of type 1 diabetes in its early stages, before insulin-producing cells have been destroyed.

The discovery has wider repercussions, as the protein is responsible for protecting the body against excessive immune responses, and could be used to treat, or even prevent, other immune disorders such as multiple sclerosis and rheumatoid arthritis.

Robots learn to take a proper handoff by following digitized human examples

A humanoid robot can receive an object handed to it by a person with something approaching natural, human-like motion thanks to a new method developed by scientists at Disney Research, Pittsburgh in a project partially funded by the International Center for Advanced Communication Technologies (interACT) at Carnegie Mellon University and Karlsruhe Institute of Technology (KIT).

Front-row seats to climate change

By day, insects provide the white noise of the South, but the night belongs to the amphibians. In a typical year, the Southern air hangs heavy from the humidity and the sounds of wildlife.

The Southeast, home to more than 140 species of frogs, toads and salamanders, is the center of amphibian biodiversity in our nation. If the ponds and swamps are the auditorium for their symphonic choruses, the scientists of the U.S. Geological Survey's Amphibian Research and Monitoring Initiative, or ARMI, have front-row seats.

New malaria test kit gives a boost to elimination efforts worldwide

A new, highly sensitive blood test that quickly detects even the lowest levels of malaria parasites in the body could make a dramatic difference in efforts to tackle the disease in the UK and across the world, according to new research published in the Journal of Infectious Diseases.

Add boron for better batteries

Frustration led to revelation when Rice University scientists determined how graphene might be made useful for high-capacity batteries.

Calculations by the Rice lab of theoretical physicist Boris Yakobson found a graphene/boron anode should be able to hold a lot of lithium and perform at a proper voltage for use in lithium-ion batteries. The discovery appears in the American Chemical Society's Journal of Physical Chemistry Letters.

Research into carbon storage in Arctic tundra reveals unexpected insight into ecosystem resiliency

(Santa Barbara, Calif.) –– When UC Santa Barbara doctoral student Seeta Sistla and her adviser, environmental studies professor Josh Schimel, went north not long ago to study how long-term warming in the Arctic affects carbon storage, they had made certain assumptions.

Artificial forest for solar water-splitting

In the wake of the sobering news that atmospheric carbon dioxide is now at its highest level in at least three million years, an important advance in the race to develop carbon-neutral renewable energy sources has been achieved. Scientists with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) have reported the first fully integrated nanosystem for artificial photosynthesis. While "artificial leaf" is the popular term for such a system, the key to this success was an "artificial forest."

No reason for Amazon and Apple to use proprietary e-book markets

There are no technical or functional reasons for Amazon and Apple to fence off their e-book worlds using proprietary e-book formats.

This is the result of a research study conducted by Professor Dr. Christoph Bläsi and Professor Dr. Franz Rothlauf of Johannes Gutenberg University Mainz (JGU) and handed over today to Neelie Kroes, EU Commissioner for the Digital Agenda, in Brussels.
