Un equipo internacional, con participación del Instituto de Astrofísica de Canarias (IAC), ha detectado la galaxia con formación estelar explosiva más lejana, que además arrancó su producción cuando el universo era muy joven. Esta galaxia crea unas 3.000 estrellas al año, mientras que...

A team of geoscientists from Southwest Research Institute using newly available remote-sensing technology has achieved unprecedented detail in quantifying subtle, long-period changes in the water levels of shallow lakes and ponds in hard-to-reach Arctic wetlands. Fuente :...

Although advances in agronomy, breeding, and biotechnology have dramatically increased corn grain yields, soil test values indicate that producers may not be supplying optimal nutrient levels. Moreover, many current nutrient recommendations, developed decades ago using outdated agronomic management...

A new study with college roommates shows that a particular style of thinking that makes people vulnerable to depression can actually "rub off" on others, increasing their symptoms of depression six months later. The research, from psychological scientists Gerald Haeffel and Jennifer Hames of the...

Biocontrol programs use an invasive plant's natural enemies (insects and pathogens) to reduce its population. Most biocontrol programs combine many different enemies. Some combinations of enemy species can actually end up competing or interfering with each other, instead of attacking the weed....

A new report on the potential effects of climate change on NOAA's Olympic Coast National Marine Sanctuary uses existing observations and science-based expectations to identify how climate change could affect habitats, plants and animals within the sanctuary and adjacent coastal areas. Fuente :...

A study just published by scientists at University of Hawai'i -- Manoa's School of Ocean and Earth Science and Technology and Randy Honebrink of the Hawai'i DLNR Division of Aquatic Resources sheds new light on the relatively rare but occasionally recorded presence of white sharks in waters surrounding the Hawaiian Islands, and...

Numerous epidemiologic studies have shown that a diet high in salt is associated with an increased risk of gastric cancer. Now Timothy L. Cover and colleagues of Vanderbilt University show that high dietary salt combined with infection by the ulcer-causing bacterium Helicobacter pylori greatly increases the risk of cancer....

The American Society for Radiation Oncology has issued a new white paper, "Assuring Safety and Quality in Image Guided Delivery of Radiation Therapy," that recommends best practices to improve the safety and effectiveness of image guided radiation therapy (IGRT), according to the manuscript published as an article in press...

A long Chandra observation reveals the SN 1006 supernova remnant in exquisite detail. By overlapping 10 different pointings of Chandra's field-of-view, astronomers have stitched together a cosmic tapestry of the debris field that was created when a white dwarf star exploded, sending its material...

A team of astronomers has discovered a dust-filled, massive galaxy churning out stars when the cosmos was a mere 880 million years old -- making it the earliest starburst galaxy ever observed. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/1...

Researchers have discovered how the protein that blocks HIV-1 from multiplying in white blood cells is regulated. HIV-1 is the virus that causes AIDS, and the discovery could lead to novel approaches for addressing HIV-1 “in hiding” – namely eliminating reservoirs of HIV-1 that persist in patients...

El pez cebra permite ver a través de su piel, toda su información se comparte con espíritu 'open access' y desde hoy tiene su mapa genético secuenciado y ordenado en la web. Este animal, mucho más barato que los roedores, promete conquistar los laboratorios ||| Fuente :...

Un equipo internacional de investigadores ha secuenciado el genoma de un pez relicto, el celacanto, según publican en Nature. Los resultados proporcionan  gran cantidad de información sobre los cambios genéticos que acompañaron a los animales acuáticos que se adaptaron al medio terrestre y, por tanto, a una mejor...

La biología del pez cebra, pequeño y transparente, y la alta similitud entre su genoma y el del ser humano lo señalan como un candidato perfecto para el estudio de enfermedades humanas como el alzhéimer o el cáncer.
