Colic affects about one in five infants in the United States annually and accounts for numerous pediatric visits during the first several months after birth.

Among the many claims of probiotic marketing is that it helps with reduction of colic symptoms but a phase III, double blind, randomized placebo controlled trial published in the British Medical Journal concluded that the use of the probiotic L reuteri for infant colic did not reduce crying or fussing in infants nor was it effective in improving infant sleep, functioning or quality of life.

The results were no different for babies receiving breast milk or formula.

Astronomers using NASA's Kepler Space Telescope report discovery of the first Earth-size planet orbiting a star in the "habitable zone" -- the range of distance from a star where liquid water might pool on the surface of an orbiting planet.

The discovery of Kepler-186f confirms that planets the size of Earth exist in the habitable zone of stars other than our sun. While planets have previously been found in the habitable zone, they are all at least 40 percent larger in size than Earth and understanding their makeup is challenging. Kepler-186f is more reminiscent of Earth.

NEW YORK, NY (April 16, 2014) — The cause of neuronal death in Parkinson's disease is still unknown, but a new study proposes that neurons may be mistaken for foreign invaders and killed by the person's own immune system, similar to the way autoimmune diseases like type I diabetes, celiac disease, and multiple sclerosis attack the body's cells. The study was published April 16, 2014, in Nature Communications.

An international research team has identified a new superbug that caused a bloodstream infection in a Brazilian patient.

The new superbug is part of a class of highly-resistant bacteria known as methicillin-resistant Staphylococcus aureus or MRSA, which is a major cause of hospital and community-associated infections. The superbug has also acquired high levels of resistance to vancomycin, the most common and least expensive antibiotic used to treat severe MRSA infections worldwide.

The world could be less than 40 years away from a food shortage that will have serious implications for people and governments, according to a senior science advisor at the U.S. Agency for International Development. It's not Paul Ehrlich/John Holdren Doomsday Prophet levels of gloom, but it's a sign we need to keep science advancing.

Children with Tourette syndrome may unconsciously train their brain to more effectively control their tics.

How so? A recent study found that teenagers diagnosed with  Tourette syndrome   were slower than typical peers when asked to perform a task that involved them simply moving their eyes to look at targets but buterr when the task was more demanding and required them to choose between looking at or away from targets. They were as fast as their peers but made fewer eye movements in the wrong direction.
