Bisphenol A (BPA) is a chemical that is used in a variety of consumer products, such as water bottles, dental composites and resins used to line metal food and beverage containers. 

It is also used in thermal paper cash register receipts and a new paper finds that is cause for concern. BPA has not been found to be harmful by the Centers for Disease Control, they say levels from all sources is 1/1000th safe levels for the US, the EU and Canada, but it is controversial due to publicity by environmental groups and the guilt-by-association taint of endocrine disruption.  The FDA agrees.

NOAA's GOES-East Satellite captured the birth of Tropical Depression Nine formed over the western Bay of Campeche, Gulf of Mexico and is forecast to make a quick landfall on Mexico's Yucatan Peninsula.

The clouds associated with the depression stretched over the Yucatan Peninsula and into the western Caribbean Sea were captured on Oct. 22nd at 1600 UTC (12 p.m. EDT).

When is an immigration crisis not an immigration crisis? When people who do not live where it is happening change the definition of an immigration crisis.

A new paper from Rice University's Baker Institute for Public Policy examines historical immigration data, the "push" and "pull" factors currently motivating Mexicans and Central Americans to migrate to the U.S. and then attempts to explain why current undocumented immigration streaming across the Mexican border is not a crisis. 

Frying in oil is one of the world's most popular ways to prepare food — chicken and French-fried potatoes are staples but even candy bars and whole turkeys have joined the list of deep-friend goodness. 

Lots of oil make health claims but there is a whole range of physical, chemical and nutritional properties that can degrade oil quality when heated so a paper in the Journal of Agricultural and Food Chemistry  tested four different refined oils — olive, corn, soybean and sunflower — and reused the oil 10 times to determine which is truly the best.

Laser-powered weapons have been a staple of science-fiction movies for so long we think we know what they would look like, but we really don't.

Researchers at the Laser Centre of the Institute of Physical Chemistry of the Polish Academy of Sciences and the Faculty of Physics, University of Warsaw decided to find out, and make a real film of it. They fired an ultrashort laser pulse through the air and captured it on video and when they slowed it down they found that it looks lot like a regular bullet, and a lot like a "Star Wars" light saber - combined. 

Metastasis of breast cancer occurs when cells move from the primary tumor to other parts of the body.

Children with autism spectrum disorder, a range of conditions characterized by social deficits and communication difficulties, were more likely to have been exposed to higher levels of certain air toxics during their mothers' pregnancies and the first two years of life compared to children without the condition, according to preliminary findings presented today at the American Association for Aerosol Research annual meeting in Orlando.

Other epidemiologists have linked everything from living near farms to organic food to autism, and such studies don't actually measure anything, they just find a map of autism and then correlate it to an environmental factor, in this instance pollution and autism instances in southwestern Pennsylvania.

There’s been a lot of discussion about obesity this week. Whether or not it’s a disease (as it is in the USA now) and how this label would positively or negatively influence action taken by society and governments in addressing this large and growing burden.

This conversation is important, but I have noticed very often it ends with confusion. Questions around why we begin talking about obesity - and end discussing mental health, cancer, heart disease or diabetes. To make things even more confusing, the term ‘Non-Communicable Diseases’ might even be mentioned.

(Inside Science TV) – Who can forget the winter of 2013-2014? Record-breaking cold temperatures and heavy snowfall hit from the Rocky Mountains all the way to the East Coast.

Although the majority of Americans still believe that global warming is happening, the especially blustery winter caused some people to question whether global warming is really happening.

“Almost invariably we find that after any winter a drop off in belief in the existence of global warming," said Barry Rabe, a political scientist at the University of Michigan in Ann Arbor.

America has a health care problem. It is excellent, the best in the world, but it is expensive. Rather than solving the problems of defensive medicine costs, designed to prevent lawsuits by conducting unnecessary tests, or tort reform to prevent lawyers from convincing people they are 'suing an insurance company' so the cost won't matter, America has instead created mandates so everyone is forced to buy insurance, and then subsidized people who can't afford it.
