Income a major driver of avoidable hospitalizations across New Jersey

Science Daily - Wed, 30/07/2014 - 2:41pm
The household income of its residents is the most important factor in whether a community has high or low rates of avoidable hospital visits -- conditions that could be better managed in a doctor's office or other health care settings if treated at an early stage, according to a report.

Nature inspires a greener way to make colorful plastics

Science Daily - Wed, 30/07/2014 - 2:41pm
Long before humans figured out how to create colors, nature had already perfected the process -- think stunning, bright butterfly wings of many different hues, for example. Now scientists are tapping into those secrets to develop a more environmentally friendly way to make colored plastics. Their method uses structure -- or the shapes and architectures of materials -- rather than dyes, to produce colors.

Exploring 3-D printing to make organs for transplants

Science Daily - Wed, 30/07/2014 - 2:41pm
Printing whole new organs for transplants sounds like something out of a sci-fi movie, but the real-life budding technology could one day make actual kidneys, livers, hearts and other organs for patients who desperately need them. Scientists are reporting new understanding about the dynamics of 3-D bioprinting that takes them a step closer to realizing their goal of making working tissues and organs on-demand.

Decades-old amber collection offers new views of a lost world: Tiny grasshopper encased in amber

Science Daily - Wed, 30/07/2014 - 2:41pm
Scientists are searching through a massive collection of 20-million-year-old amber found in the Dominican Republic more than 50 years ago, and the effort is yielding fresh insights into ancient tropical insects and the world they inhabited. Perhaps the most striking discovery thus far is that of a pygmy locust, a tiny grasshopper the size of a rose thorn that lived 18- to 20-million years ago and fed on moss, algae and fungi.

Breastfeeding: Do celebrity ambassadors help the ordinary woman?

Science Daily - Wed, 30/07/2014 - 2:40pm
Breasts are the strongest symbol of female sexuality and are abundant in the media, on magazines, in adverts and in film. Celebrity breasts are depicted as objects of sexual desire and as a model for everyday women to aspire to. Broadcast images of breastfeeding however are scarce and elicit controversy and even revulsion.

Solar energy: Dyes help harvest light

Science Daily - Wed, 30/07/2014 - 2:40pm
A new dye-sensitized solar cell absorbs a broad range of visible and infrared wavelengths. Dye-sensitized solar cells rely on dyes that absorb light to mobilize a current of electrons and are a promising source of clean energy. Scientists have now developed zinc porphyrin dyes that harvest light in both the visible and near-infrared parts of the spectrum.

An Accidental Wikipedia Hoax

Slashdot - Wed, 30/07/2014 - 2:22pm
Andreas Kolbe writes: The Daily Dot's EJ Dickson reports how she accidentally discovered that a hoax factoid she added over five years ago as a stoned sophomore to the Wikipedia article on "Amelia Bedelia, the protagonist of the eponymous children's book series about a 'literal-minded housekeeper' who misunderstands her employer's orders," had not just remained on Wikipedia all this time, but come to be cited by a Taiwanese English professor, in "innumerable blog posts and book reports", as well as a book on Jews and Jesus. It's a cautionary tale about the fundamental unreliability of Wikipedia. And as Wikipedia ages, more and more such stories are coming to light.

Square Bets Big on Next-Gen Credit Card Tech

Wired News - Wed, 30/07/2014 - 1:54pm
Square first came to fame with a credit card reader you could plug into your iPhone jack. But next year, the company’s signature device will be on its way to obsolescence as the U.S transitions to a new kind of credit card that verifies purchases with an embedded computer chip. In anticipation of this sweeping […]

Mercury's bizzare magnetic field tells scientists how its interior is different from Earth's

Science Daily - Wed, 30/07/2014 - 1:43pm
Mercury's interior is different from the Earth's interior in a way that explains Mercury's bizarre magnetic field, planetary physicists report. Measurements from NASA's Messenger spacecraft have revealed that Mercury's magnetic field is approximately three times stronger at its northern hemisphere than its southern one.

Toward a home test for detecting potentially dangerous levels of caffeine

Science Daily - Wed, 30/07/2014 - 1:43pm
The shocking news of an Ohio teen who died of a caffeine overdose in May highlighted the potential dangers of the normally well-tolerated and mass-consumed substance. To help prevent serious health problems that can arise from consuming too much caffeine, scientists are reporting progress toward a rapid, at-home test to detect even low levels of the stimulant in most beverages and even breast milk.

Hope for more accurate diagnosis of memory problems

Science Daily - Wed, 30/07/2014 - 1:40pm
More accurate tests could be created to diagnose diseases such as Alzheimer's or memory problems stemming from head injuries, leading to earlier intervention, according to new findings from researchers. The research involved investigating the components of memory using a combination of tests and neuroimaging -- a method that could be used to create a diagnostic tool for distinguishing between different types of dementia, memory damage from stroke or forms of amnesia caused by head trauma.

Sugar mimics guide stem cells toward neural fate

Science Daily - Wed, 30/07/2014 - 1:40pm
Many growth factors that influence the fate of embryonic stem cells must bind to sugars attached to specific receptors on the surface of the cell to work. Because the sugars are difficult to manipulate, biochemists created synthetic stand ins that helped to identify substructures recognized by a growth factor involved in neural development.
