Light contains fingerprints of materials that can be detected by sensors that capture the unique set of reflected wavelengths. The technique was applied to Earth during NASA's Hyperspectral Infrared Imager airborne campaign. Fuente : http://www.eurekalert.org/pub_releases/2013-04/nsf...

An image from an instrument aboard NASA's Landsat Data Continuity Mission or LDCM satellite may look like a typical black-and-white image of a dramatic landscape, but it tells a story of temperature. The dark waters of the Salton Sea pop in the middle of the Southern California desert. Crops create...

New research published as an abstract in the FASEB Journal and presented at Experimental Biology 2013 on Monday, April 22, ties mushrooms to positive health outcomes in the area of weight management. A one-year, randomized clinical trial conducted by researchers at the Weight Management Center at...

Several hypotheses have been proposed to explain the higher species numbers in the tropics, but these hypotheses have never been tested for the ants, which are one of the most ecologically and numerically dominant groups of animals on the planet.New research by evolutionary biologists Dr. Corrie...

Good news for the computer industry: a team of researchers has managed to make germanium suitable for lasers. This could enable microprocessor components to communicate using light in future, which will make the computers of the future faster and more efficient. Fuente :...

Giving nitrous oxide as part of general anesthesia for noncardiac surgery doesn't increase the rate of complications and death -- and might even decrease the risk of such events, according to a pair of studies in the May issue of Anesthesia & Analgesia, official journal of the International...

Past climate change varied remarkably between regions. This is demonstrated in a new study coordinated by the international Past Global Changes (PAGES) project, which reconstructed temperature over the past 1000 to 2000 years. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/f...

A massive study analyzing gene expression data from 22 tumor types has identified multiple metabolic expression changes associated with cancer, as well as hundreds of potential drug targets that could cut off a tumor’s fuel supply or interfere with its ability to synthesize essential building...

Snot. It’s not something most of us spend a lot of time thinking about, but, for a team of researchers in Washington, D.C., it’s front and center. The team’s lead researcher will present his newest study, focused on the molecules involved in cell signaling in nasal mucus, with the hope that other...

Conventional knowledge suggests that to avoid acute mountain sickness (AMS), climbers need to “stage,” or set up camp, at a lower altitude for four days when summiting peaks as high as 4300 meters. Scientists have found that two days of staging at a moderate altitude may be enough. Fuente :...

A recent study upends the model for how dividing cells monitor the equal distribution of their chromosomes —- a process that often runs awry in cancer. By targeting Aurora B kinase, their discovery has overturned the prevailing model of advanced cell division. Fuente :...

Intensity modulated radiotherapy (IMRT) gives better results than standard radiotherapy in patients with early breast cancer, according to results from a randomized trial. IMRT is an advanced, high-precision form of radiotherapy that can deliver an even dose of radiation, thus reducing the cosmetic...

Unavoidable damage caused to the heart and lungs by radiotherapy treatment of tumors in the chest region can be limited by the administration of an ACE inhibitor, a drug commonly used in the treatment of cardiovascular disease, a group of Dutch researchers have found. Fuente :...

Number of cigarettes smoked a day and the number of years a person has smoked both increase the risk of rheumatoid arthritis, finds research in BioMed Central's open access journal Arthritis Research & Therapy. The risk decreases after giving up smoking but, compared to people who have never...

Stress triggered neuropsychiatric disorders take an enormous personal, social and economic toll on society. In the US more than half of adults are exposed to at least one traumatic event throughout their lives. Post-traumatic stress disorder is a debilitating anxiety disorder associated with...

A contact lens on the bathroom floor, an escaped hamster in the backyard, a car key in a bed of gravel: How are we able to focus so sharply to find that proverbial needle in a haystack? Scientists at the University of California, Berkeley, have discovered that when we embark on a targeted search,...

A three-dimensional image of one of the proteins that serves as an on-off switch as it binds to receptors on the surface of a cell suggests there may be a sort of main power switch that could be tripped. These surface receptors are responsible for helping cells discern light, set the heart racing,...

Scientists at the Walter and Eliza Hall Institute and their collaborators have tailor-made a new chemical compound that blocks a protein that has been linked to poor responses to treatment in cancer patients.The development of the compound, called WEHI-539, is an important step towards the design...

For the first time, scientists show that a leading cause of liver transplant, primary sclerosing cholangitis (PSC), is a distinct disease from inflammatory bowel disease, opening up new avenues for specific PSC treatments. Fuente : http://www.eurekalert.org/pub_releases/2013-04/wts...

Abnormal numbers of chromosomes are found in the cells of about 90 percent of cancers, so understanding how healthy dividing cells ensure that each of their daughters receive an equal number of chromosomes is important to cancer biology. Until recently, scientists thought they had this figured out. Now, a paper published in...

More than 1 in 270 people in the US are living with HIV and every 9.5 minutes someone is else is infected. The economic cost estimates associated with HIV/AIDS exceed 36 billion dollars a year. The development of effective drug treatments have allowed people with HIV to live longer with federal health officials now predicting...

Depression is the leading cause of disability with more than 350 million people globally affected by this disease. In addition to debilitating consequences on mental health, depression predisposes an individual to physiological disease such as heart disease, and conversely heart disease increases the risk of depression.
