| A step closer to artificial livers  | Researchers identify compounds that help liver cells grow outside the body. | Read More »  Mapping sea salt from orbit: Building better ocean and climate models  | Climate is greatly influenced by the flow of heat energy carried by ocean currents. But precisely quantifying the mixing between the ocean and the atmosphere is hampered by a lack of detail in models of the ocean and of the water cycle. And in both models, knowing the salt content of the water is essential. | Read More » No benefit of double dose antiviral drug for severe influenza, study suggests  | There are no virological or clinical benefits of giving double doses of the antiviral drug oseltamivir (Tamiflu) to patients admitted to hospital with severe influenza, finds a large study from South East Asia. | Read More » Growth factor that triggers hair follicle generation identified  | Researchers have determined the role of a key growth factor, found in limited quantities in human skin cells, that helps hair follicles form and regenerate during the wound healing process. When this growth factor, called Fgf9, was overexpressed in a mouse model, there was a two- to three-fold increase in the number of new hair follicles produced. Researchers believe that this growth factor could be used therapeutically for people with various hair and scalp disorders. | Read More » Researchers focus on a brain protein and an antibiotic to block cocaine craving  | A new study by neuroscientists demonstrates that GLT1, a protein that clears glutamate from the brain, plays a critical role in the craving for cocaine that develops after only several days of cocaine use. | Read More » Lightest exoplanet to be directly observed so far? Faint object moves near bright star  | A team of astronomers using the European Southern Observatory's Very Large Telescope has imaged a faint object moving near a bright star. With an estimated mass of four to five times that of Jupiter, it would be the least massive planet to be directly observed outside the Solar System. The discovery is an important contribution to our understanding of the formation and evolution of planetary systems. | Read More » Genome hints at markers for higher-producing, better-tasting chocolate  | The freshly sequenced genome of the most commonly cultivated cacao plant in the world is revealed in a new study. Researchers have utilized high quality DNA sequences to demonstrate the usefulness and quality of the sequence to identify genetic markers that can lead to higher yielding cocoa plants that still produce better tasting cocoa. | Read More » New study predicts rising irrigation costs, reduced yields for US corn  | Simulations predict that in 40 years, yields for corn grown for ethanol will shrink even as climate change increases the need for irrigation, according to a new study. | Read More » New way fish camouflage themselves in the ocean discovered  | Researchers found that lookdown fish camouflage themselves through a complex manipulation of polarized light after it strikes the fish skin. In laboratory studies, they showed that this kind of camouflage outperforms by up to 80 percent the "mirror" strategy that was previously thought to be state-of-the-art in fish camouflage. | Read More » New explanation for slow earthquakes on San Andreas  | New Zealand's geologic hazards agency reported this week an ongoing, "silent" earthquake that began in January is still going strong. Though it is releasing the energy equivalent of a 7.0 earthquake, New Zealanders can't feel it because its energy is being released over a long period of time, therefore slow, rather than a few short seconds. | Read More » New species of marine fish from 408 million years ago discovered in Teruel  | Researchers have studied the fossilized remains of scales and bones found in Teruel and the south of Zaragoza, ascertaining that they belong to a new fish species called Machaeracanthus goujeti that lived in that area of the peninsula during the Devonian period. The fossils are part of the collection housed in the Palaeontology Museum of Zaragoza. | Read More » | |
