Rosetta's comet lander: Pioneering Philae completes main mission before hibernation Posted: 15 Nov 2014 04:49 AM PST Rosetta's lander has completed its primary science mission after nearly 57 hours on Comet 67P/Churyumov-Gerasimenko.

Rosetta's comet lander: How (and where) is Philae? Posted: 14 Nov 2014 12:02 PM PST The current status of Rosetta's lander Philae was discussed live during a Google Hangout this afternoon, together with scientists and engineers from the mission teams at ESA and partner agencies. The teams are very happy about the lander and the successful functioning of all instruments that were operated so far.

Do spinal cord injuries cause subsequent brain damage? Posted: 14 Nov 2014 10:10 AM PST Spinal cord injuries can cause widespread and sustained brain inflammation that leads to progressive loss of nerve cells, with associated cognitive problems and depression, researchers have found for the first time.

Scientists employ satellite tags to solve whale-sized mystery Posted: 14 Nov 2014 10:10 AM PST For the first time, scientists working in the waters of Patagonia are using satellite tags to remotely track southern right whales from their breeding/calving grounds in the sheltered bays of Península Valdés, Argentina, to unknown feeding grounds somewhere in the western South Atlantic.

Crucial mechanism driving colliding epidemics of smoking, TB unlocked by scientists Posted: 14 Nov 2014 09:49 AM PST TB is an infectious disease that kills 1.5 million people each year and smoking is the biggest driver of the global TB epidemic. Medical scientists have unlocked the mechanism underlying the connection between smoking and Tuberculosis. This discovery will considerably strengthen anti-smoking efforts to control TB and uncovers new therapy and vaccine options for TB.

New imaging technique identifies receptors for targeted cancer therapy Posted: 14 Nov 2014 09:49 AM PST A fluorescence imaging technique has been developed that can more accurately identify receptors for targeted cancer therapies without a tissue biopsy. "Accurately determining the population of protein receptors in a tumor available for targeting by molecular therapies or diagnostic imaging agents can greatly impact oncology patient outcomes," said one investigator. "Our in vivo receptor concentration imaging technique is a novel approach for fluorescence imaging that can potentially impact clinical assessment of tumor status and malignant tissue classification."

Cutting-edge computer software helps pinpoint aggressiveness of breast cancer tumors Posted: 14 Nov 2014 09:49 AM PST Cutting-edge genetic mutation-analysis software is being used to interpret mutations in tumor genomes that may provide insight into determining which breast cancer tumors are more likely spread to other parts of the body and which ones won't.

Rocky Mountain storms lead to new findings about hailstones Posted: 14 Nov 2014 09:49 AM PST New research shows that hailstones form around biological materials, extending previous findings about the formation of snow and rain.

Chemical in coffee may help prevent obesity-related disease Posted: 14 Nov 2014 09:49 AM PST A chemical compound commonly found in coffee may help prevent some of the damaging effects of obesity. Scientists have found that chlorogenic acid, or CGA, significantly reduced insulin resistance and accumulation of fat in the livers of mice who were fed a high-fat diet.

DNA sequencing helps identify genetic defects in glaucoma Posted: 14 Nov 2014 09:49 AM PST Scientists have sequenced the mitochondrial genome in glaucoma patients to help further understanding into the genetic basis for the disease. Glaucoma is a major cause of irreversible blindness, affecting more than 60 million people worldwide, increasing to an estimated 79.6 million people by 2020. It is thought that the condition has genetic origins and many experiments have shown that new sequencing approaches could help understand how the condition develops.

Smartphones team-up with QR codes for secure 3-D displays Posted: 14 Nov 2014 09:47 AM PST Quick Response (QR) codes -- the box-shaped symbols that appear on signs, posters, and even business cards -- are a convenient and efficient way of accessing specific web pages with a smartphone or other mobile device. However, new research explains how QR codes can do much more.

Theologian examines implications of 13th century manuscripts of Saint Francis of Assisi Posted: 14 Nov 2014 09:44 AM PST With the arrival in the United States earlier this week of several manuscripts from the Sacred Convent of St. Francis in Assisi, Italy, a theology professor and specialist in St. Francis, has her own tale to tell about encountering these 700-year-old documents.

Sleep apnea may contribute to kidney disease progression Posted: 14 Nov 2014 09:44 AM PST Sleep apnea may accelerate kidney function decline in diabetic patients with kidney disease, a study shows. "This study shows that a high-risk score for obstructive sleep apnea is common in non-dialysis chronic kidney disease (CKD) patients with diabetic nephropathy and is associated with more rapid loss of renal function," the investigators concluded. "This simple approach identifies patients at higher risk of CKD progression."

Nerve block procedure is safe in children, report researchers Posted: 14 Nov 2014 09:43 AM PST A regional anesthesia procedure widely used for surgery in infants and young children is effective and safe, with a minimal rate of serious complications, concludes a large database study.

First successful delivery of dialysis in Ebola virus disease provided Posted: 14 Nov 2014 09:43 AM PST Acute kidney injury occurs frequently in Ebola virus disease; however, providing hemodialysis to these patients was previously thought to be too risky. Clinicians recently accomplished the first known successful delivery of renal replacement therapy with subsequent recovery of kidney function in a patient with Ebola virus disease.

Could Depression Actually Be a Form of Infectious Disease? Posted: 14 Nov 2014 09:43 AM PST Major depressive disorder (MDD) should be re-conceptualized as an infectious disease, according to a professor. A new article suggests that major depression may result from parasitic, bacterial, or viral infection. The article presents examples that illustrate possible pathways by which these microorganisms could contribute to the etiology of MDD.

Fungus behind deadly disease in walnut trees mutates easily, complicating control Posted: 13 Nov 2014 12:55 PM PST The fungus responsible for thousand cankers disease, a lethal affliction of walnut trees and related species, has a rich genetic diversity that may make the disease more difficult to control, researchers have discovered. The researchers identified 57 distinct haplotypes, or genetic races, among the samples, a curious finding for an organism that reproduces by cloning itself. The high diversity of Geosmithia morbida likely indicates that the fungus mutates readily, said one investigator.
