At this time of year it is common to see food drives for the less fortunate - and then we see reports saying that low-income people are disproportionately obese and can't control themselves and need to be taxed more heavily in order to eat less.

How can it be both? Welcome to modern American food policy.

Academics writing in Marketing Science want poor people to spend more on food and analyzed six years of sales data from over 1,700 supermarkets across the U.S. to make the case that poor people will behave as elites want if the price of food is changed. 

Though we like to think we are more enlightened, advanced or progressive than in the past, it really isn't so.

We aren't all that different from 2,000 years ago - kids were kids, parents worried the new generation would doom society, and people fought over religion and politics. Or did religion bring nations together? It depends on who you ask. A new anthropology paper says that in Mexico of 700 B.C., religion drove people apart, a lot like Islam today does with everyone outside Islam.
Humans haven't learned much in more than 2,000 years when it comes to religion and politics.

Using new images that show unprecedented detail, scientists have found that material rotating around a very young protostar probably has dragged in and twisted magnetic fields from the larger area surrounding the star. The discovery, made with the National Science Foundation's Karl G. Jansky Very Large Array (VLA) radio telescope, has important implications for how dusty disks -- the raw material for planet formation -- grow around young stars.

Scientists from James Cook University have discovered two critically endangered species of sea snakes they thought were extinct. They were basically hiding in plain sight on Ashmore Reef in the Timor Sea, they just hadn't been since in over 15 years.

A Western Australia Parks and Wildlife Officer, Grant Griffin, sent a photo of the snakes in for identification.

 "We were blown away, these potentially extinct snakes were there in plain sight, living on one of Australia's natural icons, Ningaloo Reef," says lead author Blanche D'Anastasi from the ARC Centre of Excellence for Coral Reef Studies at JCU. "What is even more exciting is that they were courting, suggesting that they are members of a breeding population." 

We think of small talk as a way to pass the time or kill an awkward silence but a group of evolutionary psychologists are suggesting that these idle conversations could be a social-bonding tool passed down through evolution - well, in their press release they write "passed down from primates", which shows why you should be wary of psychologists discussing science.

It has been long-established that mental health and behavioral problems such as alcohol and drug abuse are risk factors that push teens to smoke. A new study finds that less destructive kids will opt for e-cigarettes instead of cancer-causing cigarettes.

That's a win for the future of public health, where smoking is linked to numerous maladies.

 In recent years, smoking has declined in middle and high school students, but the use of electronic cigarettes in this group tripled from 2013 to 2014, according to the Centers for Disease Control and Prevention. The hope is that they are using them to wean off cigarettes and will not cause a nicotine addiction that pushes young people into smoking.
