Type 2 diabetes is the most common form of diabetes, a condition characterized by high blood sugar levels.

Ancient Antarctic forests were like nothing seen on Earth today, new research reveals. The polar trees had features of today's tropical trees and may have been mixed evergreen and deciduous.

A self-described "biohacker" had a big electronic chip -- almost as big as a deck of cards -- inserted beneath the skin of his arm. Without a doctor's help. And without anesthetics.

No water has flowed across Antarctica's Friis Hills for 14 million years. But when Earth's climate was warmer, fossils show, tundra mosses and a lake covered the flat-topped hills.

You've probably heard of 3D printing--but now there's 4D printing, making materials that can change shape over time. The U.S. Army has invested $855,000 in three universities to develop the technique.

The three-rotor SwitchBlade, a small, collapsible drone that's already raised $32,810 on Kickstarter, is designed to compete with radially symmetric quadrotors in the realms of search and rescue, infrastructure inspectio...

The U.S. Senate passed a resolution to make Saturday (Nov. 2) National Bison Day, commemorating the historical, economic, ecological and cultural contributions of North America's largest land mammals.

When their normal food supply runs low, the clonal offspring of pea aphids turn to an alternative source of nutrition: parents and other adults     

The sun's activity is in free fall, according to a leading space physicist, which may slow the rise of global temperatures due to climate change. But don't expect a little ice age     

This weekend, a panel developing a new strategic plan for US particle physics will hold the first in a series of town hall meetings. Saturday begins a new stage in the process that will set priorities for US particle phy...

The streets are choked by a fog of fumigating pesticide as Nicaragua tries to combat the mosquitoes that spread dengue     

Farming has stripped the US prairies of their essential microbes. Identifying the lost bugs and putting them back could help restore the degraded land     

Syphilis has been infecting people for centuries, and many researchers have tried to pinpoint the part of the world where the bacterium that causes the disease first appeared. Despite all efforts however, the origin of s...

In a new synthesis of past work, researchers found that women consistently score lower than men on common assessments of conceptual understanding of physics. However, when examining the factors that may account for these...

Most people know about ultrasound through its role in prenatal imaging: those grainy, grey outlines of junior constructed from reflected sound waves. A new technology called an "acoustic diode," envisioned by researchers...

The mid-September floods in northern Colorado sent mud, rocks and debris flowing down mountain slopes and hillsides over an unprecedented area. Rockslides are still a danger in the aftermath of the flood.

In the aftermath of September flash floods in Colorado, landslides mar the Rocky Mountains all the way down to the foothills. Geologists warn that rockfalls will be more common for years.

People who follow a diet high in protein may initially lose weight, but such diets come with health risks of their own over time.

Diatoms have been modified while still alive to incorporate sulphur-bearing molecules that can harness chemical cargo     

Past, present, future: modern science tells us they are only an illusion. Now some maverick physicists want to restart the river of time, says Michael Slezak (full text available to subscribers)
