CIENCIA ON LINE
A better survival outcome is associated with low blood levels of squamous cell carcinoma antigen, or absence of tumor invasion either into the space between the lungs and chest wall or into blood vessels of individuals with a peripheral squamous cell carcinoma, a type of non-small cell lung...
Climate change caused by ocean, not just atmosphere
25/10/2014
|
CIENCIA ON LINE
Most of the concerns about climate change have focused on the amount of greenhouse gases that have been released into the atmosphere. A new study reveals another equally important factor in regulating the earth's climate. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/K...
Some like it loud: Warning coloration paved the way for louder, more complex calls in poisonous frogs
25/10/2014
|
CIENCIA ON LINE
Species of poison frogs that utilize bright warning coloration as protection from predators are more likely to develop louder, more complex calls than relatives that rely on camouflage. New research indicates that because these visual cues establish certain species as unsavory prey, they are free...
Law of the Sea authorizes animal tagging research without nations' consent, experts say
25/10/2014
|
CIENCIA ON LINE
Scientists who study migratory marine animals can rarely predict where the animals' paths will lead. Researchers now argue that coastal nations don't have precedent under the law of the sea to require scientists to seek advance permission to remotely track tagged animals who may enter their...

NASA's Fermi satellite finds hints of starquakes in magnetar 'storm'
25/10/2014
|
CIENCIA ON LINE
NASA's Fermi Gamma-ray Space Telescope detected a rapid-fire "storm" of high-energy blasts from a highly magnetized neutron star, also called a magnetar, on Jan. 22, 2009. Now astronomers analyzing this data have discovered underlying signals related to seismic waves rippling throughout the...
