Before there was a war on wheat and a war on sugar, there was a war on dairy products. Nutritionists need science insight the most and are least likely to want it, they instead listen to Yogic flying instructors, actresses and Food Babes at conferences embracing the latest fad.

New findings have resolved a decades-old puzzle about a fog of low-energy X-rays observed over the entire sky. Thanks to refurbished detectors first flown on a NASA sounding rocket in the 1970s, astronomers have now confirmed the long-held suspicion that much of this glow stems from a region of million-degree interstellar plasma known as the local hot bubble, or LHB. 

At the same time, the study also establishes upper limits on the amount of low-energy, or soft, X-rays produced within our planetary system by the solar wind, a gusty outflow of charged particles emanating from the sun. 

Mission Accomplished. Now it's time to go back home.

After two space shuttle missions and almost two decades, astronaut Mike Massimino has left NASA for Columbia University in New York. During the final servicing mission of the Hubble Space Telescope in 2009, Massimino became the first astronaut to tweet from space, and he now has nearly 1.3 million followers.

Marketing experts have long wanted a reliable method of forecasting responses to products and messages.

A study that analyzed the brain responses of 16 individuals says even a few people can be a remarkably strong predictor of the preferences of large TV audiences, up to 90 percent in the case of Super Bowl commercials.

This is far superior to the wobbly claims made by psychology surveys. 

In Lewis Caroll's novel "Alice in Wonderland", the Cheshire Cat could disappear but its grin remained.  Why? Who knows? Like dogs named Checkers and Esther Williams swimming pools, things don't always make sense. Scientifically, that cat was an object separated from its properties - it was a quantum cat.

Achalasia is a rare disease, affecting 1 in 100,000 people, characterized by a loss of nerve cells in the esophageal wall and manifested as chest pain during eating, weight loss, and regurgitation of food.

When we swallow, a sphincter in the lower esophagus opens, allowing food to enter the stomach. Nerve cells in the esophageal wall control the opening and closing of this sphincter, but in people with achalasia, these nerve cells gradually disappear. Without these cells, the esophageal sphincter fails to relax, causing food to accumulate in the esophagus. This results in the swallowing problems, regurgitation, vomiting, nighttime coughing, chest pain and weight loss. 

Two new papers postulate that there will be a water crisis by 2040. Not because of population, but because of current energy and power solutions.  And they believe solar and wind power is the only answer.

 In most countries, electricity is the biggest source of water consumption because the power plants need cooling cycles in order to function and that is why the scholars from Aarhus University in Denmark, Vermont Law School and CNA Corporation, a federally-funded research center for the United States Navy and Marine Corps, advocate solar and wind energy over existing technology.

Teach For America is a group that recruits recent college graduates to teach in poorer public schools for two years, the idea being that they would be better than substitute teachers in those districts. Education unions dislike the organization and call them 'scabs' - because they are non-union labor.

Now, Teach for America is setting its sights on capturing school board seats across the nation. They are never going to win over an education union that wants to protect tenure and jobs, but if they win the school board, their goal of reforming education may succeed

Beginning in 1969, a court decision, motivated by a lack of racial integration in schools, led to students being shipped to schools in other neighborhoods. As part of a political campaign against Richard Nixon, his political opposition latched onto this forced busing and school desegregation to show they cared about minorities more. The trade-off was that kids were no longer in their own neighborhoods and felt like pawns in a culture war.

Though many people believe that CO2 is the most abundant greenhouse gas in the atmosphere, that honor actually goes to water vapor. NASA has been saying for years that water vapor is the biggest amplifier in global warming, perhaps double the effect of CO2,  and a new study from scientists at the University of Miami confirms rising levels of water vapor in the upper troposphere will intensify climate change impacts over the next decades.
