Steadier Traffic Flow Improves Health of Local Infants, Researchers Say - 0 views
-
"The creation of E-ZPass lanes over the past 15 years has significantly improved the health of newborn babies living near highways in the Northeast, according to a Columbia study. The researchers found that reductions in traffic congestion generated by E-ZPass lanes reduced premature birthrates by 10.8 percent and low birth weight by 11.8 percent among infants born within 2 kilometers of toll plazas. The net effect has led to hundreds of millions of dollars in saved medical costs."
UN: Fight climate change with free condoms - 0 views

"(AP) -- The battle against global warming could be helped if the world slowed population growth by making free condoms and family planning advice more widely available, the U.N. Population Fund said Wednesday."
Studies suggest males have more personality - 0 views
-
"Males have more pronounced personalities than females across a range of species - from humans to house sparrows - according to new research. Consistent personality traits, such as aggression and daring, are also more important to females when looking for a mate than they are to males. Research from the University of Exeter draws together a range of studies to reveal the role that sexual selection plays in this disparity between males and females."

Out There: Water, Water Everywhere -- Space.com - 0 views

It's now official that water has been found on the moon, and scientists have long seen it on Mars as well. In fact, water is all over the solar system and the rest of the galaxy - and since water is key to life as we know it, these discoveries raise the hope that we are not in fact alone.
Concepts are born in the hippocampus - New Scientist - 0 views

A diminutive chihuahua and a lumbering Irish wolfhound look completely different, yet most us know they both belong to the concept called "dog". Now the brain regions responsible for our ability to organise the world into separate concepts have been pinpointed.
Is dark matter mostly 'dark atoms'? - physicsworld.com - 0 views
-
Physicists currently believe that most of the dark matter in the universe is made up of individual particles, and the challenge is to work out what kind of particles these are. New research, however, overturns this assumption and says that observational and experimental data are better explained if dark matter exists as composite particles - atoms of dark protons and dark electrons that are acted on by the dark-matter equivalent of the electromagnetic force.
How to ID human pluripotency :The Scientist - 0 views
-
Stem cell researchers must take more care in identifying true pluripotency in reprogrammed human cells, according to a study published online today (October 11) in Nature Biotechnology. The paper outlines strict molecular criteria for recognizing pluripotency, and warns that relying on just a single marker will muddle the field.
How to Measure What We Don't Know - 0 views

James Crutchfield, Physics Professor at the University of California at Davis, and graduate students Christopher Ellison and John Mahoney, have developed the analogy of scientists as cryptologists who are trying to glean hidden information from Nature. As they explain, "Nature speaks for herself only through the data she willingly gives up." To build good models, scientists must use the correct "codebook" in order to decrypt the information hidden in observations and so decode the structure embedded in Nature's processes.

Chiu now suspects that ALS is initiated by some still unknown agent or event. Then, as nerve cells begin to sicken and die, the nervous system tries to right itself by making microglia behave like wound-healers, secreting IGF-1 and other factors in an attempt to preserve motor neurons. "If the immune system has evolved in a way to help heal motor neurons," Chiu says.
Will Power: You Grow With The Task -- Ingenious Monkey - 20 two 5 - 0 views
-
Following Baumeister et al.'s widely cited work on self-regulation, many psychologists view will-power as a depletable resource. According to this view, whenever we perform acts of self-regulation (e.g. resisting a delicious piece of cake) we tap into our individual will-power reservoir (think of it as a bank account), and thereby reduce the amount of will-power left for subsequent tasks. According to a study published in the Journal of Applied Psychology, however, this plausible intuition does not necessarily seem to hold true entirely.
Quantum Computers Could Tackle Enormous Linear Equations / Science News - 0 views

A new algorithm may give quantum computers a new, practical job: quickly solving monster linear equations. Such problems are at the heart of complex processes such as image and video processing, genetic analyses and even Internet traffic control.
Macro-roles for MicroRNAs in the Life and Death of Neurons - Alzforum: News - 0 views
-
Until recently, the control of protein synthesis seemed straightforward and of little concern to most neuroscientists. However, the simple story of gene transcription into messenger RNA (mRNA) and subsequent translation into a protein has recently become considerably more complicated. Small RNA molecules have been discovered that can determine when and if the mRNA for a particular protein will be translated.

A new project to create a 3D map of space so large that scientists can find a 500 million-light-year-size remnant from the early universe inside it began operation last month. The Baryon Oscillation Spectroscopic Survey opened its eyes to the universe, taking in data from hundreds of galaxies and quasars in the constellation Aquarius, from its perch on the Apache Point Observatory in New Mexico. Eventually, it will image two million galaxies and quasars.

How does your galaxy grow? - New Scientist - 0 views

Together with ever-improving observations of the early universe, grand simulations are beginning to paint a single, unifying picture of why the universe looks as it does. At its heart is an almost invisible scaffold of dark matter and cold gas on which the visible constituents of the universe hang - a structure known as the cosmic web.
How Culture Shapes Our Mind and Brain | Brain Blogger - 0 views
-
Most people would agree that culture can have a large effect on our daily lives - influencing what we may wear, say, or find humorous. But many people may be surprised to learn that culture may even effect how our brain responds to different stimuli. Indeed, until recently, most psychology and neuroscience researchers took for granted that their findings translated across individuals in various cultures. In the past decade, however, research has begun to unravel how cultural belief systems shape our thoughts and behaviors.

Genomes aren't orderly and neat; they're exceedingly messy and complex, filled with "noise" from which subtle signals are difficult to filter. A disease can arise from one or two mutations, or from the cumulative action of hundreds. This means finding genome mutations responsible for diseases is both incredibly difficult and also often fruitless: The variation in individual genomes is so large that nearly every single potential disease-causing mutation typically turns out to be benign.
