Each year, 1 million men in the U.S. undergo biopsies to determine whether they have prostate cancer because ultrasound imaging cannot clearly display the location of tumors in the prostate gland.

Ultrasound has been used to visualize the prostate in order to take a representative sampling of tissue to biopsy but with MRI doctors can see specific lesions in the prostate and only take tissue samples from those spots.

Why aren't those two sampling methods used in combination?

A multidisciplinary team has found that biopsy guided by magnetic resonance imaging increases the rate of prostate cancer detection.

If you read the Harry Potter series of novels or saw the films, you've known that fiction has people moving in and out of photographs - now that magic has been brought to real life.

The University of Washington algorithm Photo Wake-Up was posted in preprint form on arXiv in December and created a buzz because it can take a person from a 2D photo or a work of art and make them run, walk or jump out of the frame. The system also allows users to view the animation in three dimensions using augmented reality tools. Next week at the Conference on Computer Vision and Pattern Recognition in Long Beach, California, the researchers will be showing results.

The Neolithic period, the end of the Stone Age and the beginning of civilizations, began about 12,000 years ago with the advent of agriculture in the Epipalaeolithic Near East. It spread to other parts of the world.

It provides not just the first evidence of farming, it also provides early evidence of gender inequality. according to a paper by researchers from the Department of Prehistory and Archaeology at the University of Seville who study prehistoric societies in the Neolithic Period in the Iberian Peninsula.

When we think of agriculture, we don't think of nomadic hunter-gatherers who simply followed nature rather than harnessing it. 

But they engaged in trade also. Millet, originally domesticated in China, was likely consumed at low levels by pastoralists inhabiting the far-flung regions of Siberia and southeastern Kazakhstan, possibly as early as the late third millennium but with the expansion of trans-regional networks across the steppe, when objects and ideas were first regularly exchanged over long-distances, millet consumption began to increase.  

It's quite common for the circle of life to have animals eating plants in order to become bigger food for other animals and then animals die and become food for organisms in the soil but nature has flipped the script again. 

A mysterious large mass of material has been discovered beneath the Moon's South Pole-Aitken basin, the largest crater in our solar system.

The crater, thought to have been created about 4 billion years ago, is oval-shaped and as wide as 2,000 kilometers (roughly the distance between Waco, Texas, and Washington, D.C.) and several miles deep. Despite its size, it cannot be seen from Earth because it is on the far side of the Moon.
