Ethnoburbs: Is It White Flight Or Creating Neighborhood Enclaves?

August 16, 2014 - 9:30pm

"White flight" was the term created by sociologists for when people middle-class began moving from poor city neighborhoods to newly created sub-urban communities that were not city apartments and townhouses but not rural either - suburbs.

Hormone Mimics: A New Way To Capture Them

August 16, 2014 - 8:45pm
Chemicals known as hormone mimics may damage our ability to reproduce and pollute the natural environment. Now there may be a new way of capturing them.

In a laboratory in Trondheim, researchers have managed to create minute particles with some very desirable properties, such as the ability to capture and break down any hormone mimics that have ended up in our waste water. These unwanted chemicals come from the kind of consumer items that make our lives easier and more comfortable. But they have consequences.

Carbon Monoxide May Prevent Arrhythmia After Heart Attack

August 16, 2014 - 1:30pm
A new study has found that carbon monoxide could be used to protect against life-threatening arrhythmias after a heart attack.

Restoring blood flow to the heart following a heart attack can leave patients with ventricular fibrillation, a dangerous heart rhythm which puts people at greater risk of sudden cardiac death. Previous research has shown carbon monoxide, which is produced naturally in heart cells, can guard against ventricular fibrillation, however the mechanism behind why this happens was unknown.

Scientists at Aston University in Birmingham (UK) and Peking University in China have found carbon monoxide works by blocking the channels that carry potassium into heart cells – an essential process required to reset the cells before their next heartbeat. -->

All Our Brains Generate Emotions The Same Way

August 16, 2014 - 1:00pm
By Joel N. Shurkin, Inside Science

(Inside Science) -- In an analogy many scientists hate, the human brain is often compared to a small, wet computer, functioning in almost the same way as the electronic kind. Two scientists at Cornell University report the analogy might be closer to the truth than anyone thought.

They have found an emotion code.

Experimental Heart Attack Drug APT102 Reduces Tissue Damage

August 16, 2014 - 12:00pm
An investigational drug known as APT102 significantly reduced damage to heart muscle from a heart attack and minimized the risk of bleeding during follow-up treatments, according to an animal study based on a decade of work by APT Therapeutics, scientists at Washington University School of Medicine in St. Louis and colleagues at Cornell and Harvard.

Standard heart attack treatment often causes heart tissue damage. Once the blood clot that causes a heart attack is removed from an artery, molecules from dead and dying cells mix with blood rushing back through the artery. One of these molecules, adenosine triphosphate (ATP), is inflammatory; another, adenosine diphosphate (ADP), causes more clotting.

Asimov’s Three Laws Of Robotics Get A 21st Century Health Care Update

August 16, 2014 - 3:23am
Isaac Asimov's Three Laws Of Robotics, from the story "Runaround" in 1942, are arguably the most famous example of fictional ethics becoming so fundamental they are adopted spontaneously by everyone in an industry that hadn't even been created yet.(1)

Now that robots are widely used in caring for older people, as well as in military and industrial applications, scholars want to give them a 21st century update.

Magpies Are Only 3 Percent The Thieves We Think They Are

August 16, 2014 - 12:14am

In European culture, it is widely accepted that magpies (Pica pica) are the thieves of the bird kingdom, attracted to sparkly things and prone to stealing them for their nests.

But psychologists at the Centre for Research in Animal Behaviour (CRAB) at the University of Exeter have analyzed magpies and found that the species is actually frightened of new and unfamiliar objects rather than attracted to them. 

The researchers carried out a series of experiments with both a group of magpies which had come from a rescue center, and wild magpies in the grounds of the University. The birds were exposed to both shiny and non-shiny items and their reactions recorded.

Gut Bacteria: Now Assuming Control Of Your Brain

August 15, 2014 - 9:30pm

It sounds like science fiction, but a new paper in the journal BioEssays
 says that bacteria within us — which outnumber our own cells about 100-fold — may very well be affecting both our cravings and moods to get us to eat what they want, and often are driving us toward obesity. 

The scholars from UC San Francisco, Arizona State University and University of New Mexico concluded that from a review of the recent scientific literature that microbes influence human eating behavior and dietary choices to favor consumption of the particular nutrients they grow best on, rather than simply passively living off whatever nutrients we choose to send their way.

Senior Author, First Author - New Algorithm Sheds Light On Crediting Research Properly

August 15, 2014 - 9:07pm

There has always been a bit of good-natured humor when it comes to who gets credit for what in a long line of citations.

Occasionally, it can be strange, like when one person who contributed to the I.P.C.C. claims to be a Nobel laureate, but most often there is a pecking order to science papers.

This does not keep science humorosts like Jorge Cham at PhDComics.com from cutting to the heart of the matter, as they did on figuring out citations way back in 2005:

Parenting Before Conception: You Aren't Locked Into An Epigenetic Destiny

August 15, 2014 - 7:20pm

There's evidence that a child's future health is influenced by more than just their parents' genetic material and can be impacted by environmental factors, but what is being done with that is something of a concern.

Diffuse Interstellar Bands: Material Mystery In The Milky Way

August 15, 2014 - 6:23pm

Astronomers have produced new maps of the material located between the stars in the Milky Way, which could move science closer to cracking a stardust puzzle nearly a century old.

 The researchers say their work demonstrates a new way of uncovering the location and eventually the composition of the interstellar medium—the material found in the vast expanse between star systems within a galaxy. 

This material includes dust and gas composed of atoms and molecules that are left behind when a star dies. The material also supplies the building blocks for new stars and planets.

Laser Makes Microscopes Way Cooler, As In -265 Degrees Celcius

August 15, 2014 - 4:00pm

Laser physicists have found a way to make atomic-force microscope probes 20 times more sensitive, using laser beams to cool a nanowire probe to minus 265 degrees Celsius. 

Atomic force microscopes achieve extraordinarily sensitivity measurements of microscopic features by scanning a wire probe over a surface.
The technique makes it capable of detecting forces as small as the weight of an individual virus.

The development could be used to improve the resolution of atomic-force microscopes, which are the state-of-the-art tool for measuring nanoscopic structures and the tiny forces between molecules.

In Europe, Criticizing Wealthy, Environmentally Aware Travelers Is A CO2 Taboo

August 15, 2014 - 4:00pm

Transport accounts for an up to 30% of CO2 emissions in the EU, with estimates claiming that emissions from that sector rose 36% between 1990 and 2007. 

A new analysis conducted by Lund University and the University of Surrey takes on the widely-held view that new technologies, such as biofuel and improved aircraft design, will result in carbon reduction targets being met.

Galileons And Ghostly Degrees Of Freedom

August 15, 2014 - 2:47pm

There has been discussion among cosmologists about galileons, a hypothetical class of effective scalar fields which are extremely universal and arise generically in describing the short distance behavior of the new degrees of freedom introduced during the process of modifying gravity, and in describing the dynamics of extra dimensional brane worlds.  They might be able to explain dark matter - no cosmological constant needed.

Despite prolific use of the term 'theory', they are math that hopes to become physics.

Turn Carbon Dioxide Into Useful Chemicals Using Foam

August 15, 2014 - 2:33pm

A catalyst made from a foamy form of copper has vastly different electrochemical properties from catalysts made with smooth copper in reactions involving carbon dioxide, a new study shows. The research suggests that copper foams could provide a new way of converting excess CO2 into useful industrial chemicals.

As levels of carbon dioxide in the atmosphere continue to rise, researchers are looking for ways to make use of it. One approach is to capture CO2 emitted from power plants and other facilities and use it as a carbon source to make industrial chemicals, most of which are currently made from fossil fuels. The problem is that CO2 is extremely stable, and reducing it to a reactive and useful form isn't easy.

Reduced Testosterone Tied To Phthalates

August 15, 2014 - 12:00pm

Men, women and children exposed to high levels of phthalates tended to have reduced levels of testosterone in their blood compared to those with lower chemical exposure, according to a new paper in the Endocrine Society's Journal of Clinical Endocrinology&Metabolism.

Testosterone is the main sex hormone in men. It contributes to a variety of functions in both sexes, including physical growth and strength, brain function, bone density and cardiovascular health. In the last 50 years, research has identified a trend of declining testosterone in men and a rise in related health conditions, including reduced semen quality in men and genital malformations in newborn boys.

The Periodic Diet

August 15, 2014 - 11:44am
It is a well-known fact that given the availability of food, we eat far more than what would be healthy for our body. Obesity has become a plague in many countries, and the fact that it correlates very tightly with a decreased life expectancy is not a random chance but the demonstrated result of increased risk of life-threatening conditions connected with excess body fat.

Yet we eat, and drink, and eat. We look like self-pleasing monkeys trained to press a button to self-administer a drug. To make matters worse, many of the foods and drinks we consume contain substances purposely added to increase our addiction. So it takes a strong will to control our body weight.

Spider Personalities Can Tell Us Which Are The Best Parents

August 15, 2014 - 10:30am
A new paper delineating spiders’ roles within their colonies is intriguing because the spiders’ specialization (like caregiver or hunter-warrior) isn’t determined by size or physical structure, like with ants, but by personalities.

Aren't spiders loners? Most are, but a few species such as Anelosimus studiosus live in groups.

Colin Wright, a second-year PhD student in the University of Pittsburgh’s Department of Biological Sciences, along with Jonathan Pruitt, assistant professor of behavioral ecology at Pitt and Tate Holbrook of the College of Coastal Georgia, separated docile spiders from the aggressive by observing how much space they demanded from fellow colony members. Aggressive females demand more space than docile ones.
