Think you're extreme? 12,000 years ago Ice Age Humans lived and worked at an altitude of almost 15,000 feet, high in the Peruvian Andes.

The sites in the Pucuncho Basin, located in the Southern Peruvian Andes, are the highest-altitude Pleistocene archaeological sites found to-date. The primary site, Cuncaicha is a rock shelter at 4,480 meters above sea level, with a stone-tool workshop below it. There is also a Pucuncho workshop site where stone tools were made at 4,355 meters above sea level.

White children diagnosed with type 1 diabetes increased significantly from 2002 to 2009 in all but the youngest age group, according to a new paper in Diabetes.

A new study finds that though most U.S. adults fail to meet recommended daily levels of 10 key nutrients, those with disabilities do substantially worse.

At least 10 percent of U.S. adults fit into one or more category of disability, from those who have difficulties with activities of daily living, such as dressing, bathing and eating, to those who cannot use their legs or struggle to accomplish routine tasks, such as money management or household chores.

Up to 64% of people worldwide use medicinal plants to treat illnesses and relieve pain, and the herbal medicine market is worth $60 billion annually. Despite the increasing popularity of herbal medicine, the sale of medicinal plants is mostly unregulated, because they do not claim to be medicine in countries where regulation happens. 

It's obvious why people in developing nations embrace herbal alternatives to medicine - medicine is expensive. In wealthier countries, it is instead embraced by people who have plenty of money but don't trust science.

While studying the atmosphere on Saturn's moon Titan, scientists discovered intriguing zones of organic molecules unexpectedly shifted away from its north and south poles. These misaligned features seem to defy conventional thinking about Titan's windy atmosphere, which should quickly smear out such off-axis concentrations.

"This is an unexpected and potentially groundbreaking discovery," said Martin Cordiner, an astrochemist working at NASA's Goddard Space Flight Center in Greenbelt, Maryland, and the lead author of a study published online today in the Astrophysical Journal Letters. "These kinds of east-to-west variations have never been seen before in Titan's atmospheric gases. Explaining their origin presents us with a fascinating new problem."

A new study found that people ages 60 and older who do not have dementia benefit from light alcohol consumption; it has been associated with higher episodic memory, the ability to recall memories of events. 

Moderate alcohol consumption was also linked with a larger volume in the hippocampus, a brain region critical for episodic memory. The relationship between light alcohol consumption and episodic memory goes away if hippocampal volume is factored in, providing new evidence that hippocampal functioning is the critical factor in these improvements.
