Yoga: How true it reduces heart disease risk

The most common form of heart disease affecting humans is the Coronary Artery Disease. The disease portrays acute build-up of cholesterol in the layers of the arteries constituting the heart. The blockage induces a phenomenal slowed down blood circulation. The left auricle functions in generating the signals dubbed as heart beats. As a result of the incrementing inadvertent blockage the muscles keep panting due to the lack of supply of blood to the muscles. Since the blood supply to the muscles are snapped to an instance, the muscles are forced to reciprocate to the bodily functions. The plaques present in the arterial walls of all humans suffice huge pressure in the process which may lead to weakening and thereby a crack in the arterial wall. Again this may concur with unforeseen blood clot in the region. This compromising blood clot, topped with blockage sustaining in the arteries lead to the preponderances of heart attacks. (more…)

Tendency to Fear is Strong Political Influence

Fear can play a role in influencing political attitudes on hot-button issues like immigration, according to new research co-authored by Brown political scientist Rose McDermott. The study, published in the American Journal of Political Science, shows that individuals who are genetically predisposed to fear tend to have more negative out-group opinions, which play out politically as support for policies like anti-immigration and segregation.

PROVIDENCE, R.I. [Brown University] — It’s no secret that fear is a mechanism often used in political campaigns to steer public opinion on hot-button issues like immigration and war. But not everyone is equally predisposed to be influenced by such a strategy, according to new research by Rose McDermott, professor of political science, and colleagues published in the American Journal of Political Science.

It’s in the Genes: Research Pinpoints How Plants Know When to Flower

Scientists believe they’ve pinpointed the last crucial piece of the 80-year-old puzzle of how plants “know” when to flower.

Determining the proper time to flower, important if a plant is to reproduce successfully, involves a sequence of molecular events, a plant’s circadian clock and sunlight.

Understanding how flowering works in the simple plant used in this study – Arabidopsis – should lead to a better understanding of how the same genes work in more complex plants grown as crops such as rice, wheat and barley, according to Takato Imaizumi, a University of Washington assistant professor of biology and corresponding author of a paper in the May 25 issue of the journal Science.

New Understanding of Earth’s Mantle Beneath The Pacific Ocean

Washington, D.C. — Scientists have long speculated about why there is a large change in the strength of rocks that lie at the boundary between two layers immediately under Earth’s crust: the lithosphere and underlying asthenosphere. Understanding this boundary is central to our knowledge of plate tectonics and thus the formation and evolution of our planet as we know it today. A new technique for observing this transition, particularly in the portion of Earth’s mantle that lies beneath the Pacific Ocean basin, has led Carnegie and NASA Goddard scientist Nick Schmerr to new insight on the origins of the lithosphere and asthenosphere. His work is published March 23 in Science.

The lithosphere-asthenosphere boundary, or LAB, represents the transition from hot, convecting mantle asthenosphere to overlying cold and rigid lithosphere. The oceanic lithosphere thickens as it cools over time, and eventually sinks back into the mantle at Earth’s so-called subduction zones. (more…)

NASA Sees Repeating La Niña Hitting its Peak

La Niña, “the diva of drought,” is peaking, increasing the odds that the Pacific Northwest will have more stormy weather this winter and spring, while the southwestern and southern United States will be dry.

Sea surface height data from NASA’s Jason-1 and -2 satellites show that the milder repeat of last year’s strong La Niña has recently intensified, as seen in the latest Jason-2 image of the Pacific Ocean, available at: https://sealevel.jpl.nasa.gov/images/ostm/20120108P1.jpg. (more…)

BERKELEY, Calif. — Studying the environment would be simple if it weren’t for one thing: Even an isolated ecosystem is unbelievably complicated. Factors to study include water systems, plant life cycles, carbon dioxide fluctuations, resource use by humans, and far more — and each can be studied at the scale of a plant or of the planet, and measured in an instant or over decades.
