But one byproduct of the process is millions of gallons of water that's much saltier than seawater, after leaching salts from rocks deep below the surface. Now researchers say they have found an economical solution for removing the salt from this water.

Beyond LOL cats, social networks could become trove of biodiversity data Posted: 21 Oct 2014 08:14 AM PDT Social networks can be a viable source for photo-vouchered biodiversity records, especially those that clarify which species exist in what places within developing nations, one expert suggests.

Detecting cancer earlier is goal of new medical imaging technology Posted: 21 Oct 2014 08:14 AM PDT A new medical imaging method could help physicians detect cancer and other diseases earlier than before, speeding treatment and reducing the need for invasive, time-consuming biopsies. The potentially lifesaving technique uses nanotechnology and shortwave infrared light to reveal small cancerous tumors and cardiovascular lesions deep inside the body.

Extremely high-resolution magnetic resonance imaging Posted: 21 Oct 2014 08:14 AM PDT For the first time, researchers have succeeded to detect a single hydrogen atom using magnetic resonance imaging, which signifies a huge increase in the technology's spatial resolution. In the future, single-atom MRI could be used to shed new light on protein structures.

New analysis methodology may revolutionize breast cancer therapy Posted: 21 Oct 2014 08:13 AM PDT Stroma cells are derived from connective tissue and may critically influence tumor growth. This knowledge is not new. However, a team of researchers has developed a novel methodology for investigation. Using modern mass spectrometry, tumor-promoting activities from breast fibroblasts were directly determined from needle biopsy samples.

Researchers patent a nanofluid that improves heat conductivity Posted: 21 Oct 2014 08:12 AM PDT Researchers have developed and patented a nanofluid improving thermal conductivity at temperatures up to 400°C without assuming an increase in costs or a remodeling of the infrastructure. This progress has important applications in sectors such as chemical, petrochemical and energy, thus becoming a useful technology in all industrial applications using heat transfer systems such as solar power plants, nuclear power plants, combined-cycle power plants and heating, among other.

Exploring x-ray phase tomography with synchrotron radiation Posted: 21 Oct 2014 08:12 AM PDT X-ray phase tomography is an imaging technique that uses penetrating X-rays to create volumetric views through "slices" or sections of soft biological tissues, such as tumors, and it offers strongly enhanced contrast compared to conventional CT scans. Yet scientists still do not know which X-ray phase tomography methods are best suited to yield optimized results for a wide variety of conditions.

Big black holes can block new stars Posted: 21 Oct 2014 08:07 AM PDT Massive black holes spewing out radio-frequency-emitting particles at near-light speed can block formation of new stars in aging galaxies, a study has found.
