SUNRISE offers new insight on sun's atmosphere

Posted: 27 Sep 2013 03:33 PM PDT

Three months after the flight of the solar observatory Sunrise -- carried aloft by a NASA scientific balloon in early June 2013 -- scientists have presented unique insights into a layer on the sun called the chromosphere. Sunrise provided the highest-resolution images to date in ultraviolet light of this thin corrugated layer, which lies between the sun's visible surface and the sun's outer atmosphere, the corona.

First step to reduce plant need for nitrogen fertilizer uncovered

Posted: 27 Sep 2013 03:33 PM PDT

Nitrogen fertilizer costs US farmers approximately $8 billion each year, and excess fertilizer can find its way into rivers and streams, damaging the delicate water systems. A new discovery could be the first step toward helping crops use less nitrogen, benefiting both farmers' bottom lines and the environment.

New species of fascinating opportunistic shelter using leaf beetles

Posted: 27 Sep 2013 09:34 AM PDT

Builders are rather uncommon among adult leaf beetles though young ones of certain species use own feces to construct a defensive shield. Two closely related, hitherto unknown species of tiny southern Indian leaf beetles, only slightly larger than the size of a pin-head, and their clever way of using and modifying low cost shelters, have now been described.

3-D models of electrical streamers

Posted: 27 Sep 2013 09:32 AM PDT

New breast cancer imaging technique could cut down on false positives

Posted: 27 Sep 2013 06:27 AM PDT

A new breast cancer screening technique is being developed that has the potential to reduce false positives, and, possibly, minimize the need for invasive biopsies. Scientists have created an MRI device that could improve both the process and accuracy of breast cancer screening by scanning for sodium levels in the breast.

Breathing underwater: Evidence of microscopic life in oceanic crust

Posted: 27 Sep 2013 06:27 AM PDT

Scientists have recently documented that oxygen is disappearing from seawater circulating through deep oceanic crust, a significant first step in understanding the way life in the "deep biosphere" beneath the sea floor is able to survive and thrive. The new research findings are helping to redefine our concepts of the limits of life on our planet.

Setting blurred images in motion improves perception

Posted: 26 Sep 2013 11:29 AM PDT

Blurred images that are unidentifiable as still pictures become understandable once the images are set in motion. That's because of a phenomenon called "optic flow," which may be especially relevant as a source of visual information in people with low vision.
