Japón lanzó el 3 de agosto su cuarta nave de carga hacia la estación espacial internacional. El HTV-4 o Kounotori-4 partió desde la base de Tanegashima a las 19:48 UTC, a bordo de un potente cohete H-IIB. El vehículo, que alcanzó el espacio sin novedad, lleva suministros para los astronautas del......

Las hormigas rojas de fuego toman su nombre del dolor, semejante a una quemadura, de su picadura. Ahora parece que el mismo veneno que causa este dolor poderoso en realidad podría ser útil.Estudios por científicos del Servicio de Investigación Agrícola (ARS) en Stoneville, Misisipí (EEUU), han......

En 1798 comenzó, de la mano de Napoleón Bonaparte, una de las expediciones científicas más peculiares y provechosas de la historia, durante la campaña de Egipto. El general se hizo acompañar por docenas de científicos para que recogieran toda la información sobre los tesoros de aquel exótico país....

St. Jude Children's Research Hospital scientists have discovered a way to target the immune system to shrink or eliminate tumors in mice without causing autoimmune problems. Researchers also found evidence that the same mechanism may operate in humans. Fuente :...

Not only does practice make perfect, it also makes for more efficient generation of neuronal activity in the brain's primary motor cortex, say researchers from the University of Pittsburgh School of Medicine. Their findings, published online today in Nature Neuroscience, showed practice leads to...

By borrowing a tool from bacteria that infect plants, scientists have developed a new approach to eliminate mutated DNA inside mitochondria -- the energy factories within cells. Doctors might someday use the approach to treat a variety of mitochondrial diseases, including the degenerative eye...

Oceans cover 71 percent of the Earth's surface, yet our knowledge of the impact of climate change on marine habitats is a mere drop in the proverbial ocean compared to terrestrial systems. An international team of scientists set out to change that by conducting a global meta-analysis of climate...

Wistar researchers have led a team of scientists to determine the structure of NatA, an enzyme complex that modifies one end of most human proteins and is made at elevated levels in numerous forms of cancer. Their findings, they believe, will allow them to create an inhibitor -- a potential drug --...

Chemically modified inhibitors of the COX-2 enzyme relieve anxiety behaviors in mice by activating natural "endocannabinoids" without gastrointestinal side effects, Vanderbilt University scientists report in the journal Nature Neuroscience.Endocannabinoids are natural signaling molecules that...

In a study appearing online Aug. 4 in Nature, NYU Langone Medical Center researchers decipher how oxytocin, acting as a neurohormone in the brain, not only reduces background noise, but more importantly, increases the strength of desired signals. These findings may be relevant to autism, which...

Fatiga, dificultad para respirar, daño en los órganos y muerte prematura. Esas son las principales características de la insuficiencia cardiaca, una dolencia que solo en EE UU afecta a unos seis millones de personas.Ahora, un estudio publicado esta semana en la revista Cell revela el papel...

Research has revealed the effects of a decade of decentralized wage negotiations in the private sector. In an article in the Journal of Labor Economics, researchers conclude that wages have risen for all employees and that companies are now better able to retain key personnel. Fuente :...

It may be called the Robotic Refueling Mission (RRM), but NASA's RRM was built to demonstrate much more than the clever ways space robots can fill up satellites. With the launch of new hardware to the International Space Station on Aug. 3, RRM will be outfitted to practice a new set of satellite-servicing activities. Fuente :...

NASA's Curiosity rover will mark one year on Mars next week and has already achieved its main science goal of revealing ancient Mars could have supported life. The mobile laboratory also is guiding designs for future planetary missions. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/h...

Scientists have described findings that could enable the development of more effective drugs for addiction with fewer side effects. The study showed in a combination of cell and animal studies that one active compound maintains a strong bias towards a single biological pathway, providing insight into what future drugs could...

How is vital oxygen supplied to the tropical ocean? New research by oceanographers in Germany shows that about one third of the oxygen supply in these areas is provided by turbulent processes, such as eddies or internal waves. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/X...

Burning incense, a popular cultural practice in many parts of the world, generates indoor air pollutants that may cause inflammation in human lung cells, say researchers. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/g...

Scientists are turning to nature to find a way to make windows more energy efficient. In a recent article, researchers describe a novel process to cut down on heat loss during the winter and keep buildings cool during the summer. Their "bio-inspired approach to thermal control for cooling (or heating) building window surfaces"...

Researchers are conducting some of the first ever scientific studies of neonate pine snakes, performing snake surgery for radio tracking and helping snakes survive road crossings through the busy New Jersey shore traffic. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/0...

Research suggests that people who are vulnerable to developing alcoholism exhibit a distinctive brain response when drinking alcohol, according to a new study. Compared to people at low risk for alcohol-use problems, those at high risk showed a greater dopamine response in a brain pathway that increases desire for rewards....
