IRIS and Hinode: A Stellar research teamModern telescopes and satellites have helped us measure the blazing hot temperatures of the sun from afar. Mostly the temperatures follow a clear pattern: The sun produces energy by fusing hydrogen in its core, so the layers surrounding the core generally get cooler as you move outwards—with one exception. Two NASA missions have just made a significant step towards understanding why the corona—the outermost, wispy layer of the sun's atmosphere —is hundreds of times hotter than the lower photosphere, which is the sun's visible surface. | |

When computers learn to understand doctors' notes, the world will be a better placeTrain a computer to read medical records, and you could do a world of good. Doctors could use it to look for dangerous trends in their patients' health. Researchers could speed drugs to market by quickly finding appropriate patients for clinical trials. They could also find previously overlooked associations. By keeping track of data points across tens of thousands, or millions, of medical records, computer models could find patterns that would never occur to individual researchers. Maybe Asian women in their 40s with type 2 diabetes respond well to a certain combination of medications, while white men in their 60s do not, for example. | |
Biophysicists take small step in quest for 'robot scientist'Biophysicists have taken another small step forward in the quest for an automated method to infer models describing a system's dynamics - a so-called robot scientist.

Community of soil bacteria saves wild tobacco plants from root rotRoot bacteria are known to form symbiotic relationships with plants by improving the plants' supply of nutrients. Yet as scientists at the Max Planck Institute for Chemical Ecology in Jena, Germany, found recently, the bacteria actually play a much more profound role. During field experiments in Utah, in the western USA, researchers discovered that the right mixture of soil microbiota directly influences the survival of Nicotiana attenuata, a species of wild tobacco. Plants that had been unable to establish a protective alliance with the vitally important soil bacteria were susceptible to an infectious wilt disease that could kill them overnight. The pathogens that caused the disease had built up and spread because the researchers had been continuously growing this native plant in the same field. Moreover, a sterile medium had been used for germination before the plants had been planted out on the field, a procedure which prevente! d the plants from recruiting symbiotic bacteria early on, as they normally would do when germinating in nature. The results of the study emphasize the importance of crop rotation to prevent the buildup of soil borne diseases and reveal the complex ecology of plants, especially with respect to the multitude of beneficial and harmful microorganisms that interact with them. | |

Dung beetles found to use different celestial navigation cues depending on species(Phys.org)—A team of researchers with member affiliations to Lund University in Sweden and the University of Arizona in the U.S. has found that two species of dung beetles navigate differently depending on whether they are diurnal or nocturnal. In their paper published in Proceedings of the National Academy of Sciences, the group describes their study and offers a theory on how one species navigates when there is no light from either the sun or moon. | |
Mimic woodpecker fools competing birds, but genetics expose its true identityTo look tougher, a weakling might shave their head and don a black leather jacket, combat boots and a scowl that tells the world, "don't mess with me." | |
Rare nautilus sighted for the first time in three decadesIn early August, biologist Peter Ward returned from the South Pacific with news that he encountered an old friend, one he hadn't seen in over three decades. The University of Washington professor had seen what he considers one of the world's rarest animals, a remote encounter that may become even more infrequent if illegal fishing practices continue. | |
Sequencing of barley genome achieves new milestoneBarley, a widely grown cereal grain commonly used to make beer and other alcoholic beverages, possesses a large and highly repetitive genome that is difficult to fully sequence. Now a team led by scientists at the University of California, Riverside has reached a new milestone in its work, begun in 2000, on sequencing the barley genome. The researchers have sequenced large portions of the genome that together contain nearly two-thirds of all barley genes. | |
Algorithm helps identify elusive genes that express like clockworkGenes that express in precisely timed patterns, known as oscillatory genes, play an essential role in development functions like cell division, circadian rhythms and limb formation. But without a time-lapse view of genetic expression, these genes have gone largely undiscovered. | |
Batting practice in the genomeIn the biochemical game of genetics, it was thought that the proteins controlling gene regulation in animals were either spectators or players. | |
Power lines restrict sage grouse movement in WashingtonTransmission lines that funnel power from hydroelectric dams and wind turbines across Eastern Washington affect greater sage grouse habitat by isolating fragile populations and limiting movement, a new study finds. | |
How plant sensors detect pathogensIn the mid-20th century, an American scientist named Harold Henry Flor helped explain how certain varieties of plants can fight off some plant killers (pathogens), but not others, with a model called the "gene-for-gene" hypothesis. Seventy years later, an international team of scientists describes precisely how a plant senses a pathogen, bringing an unprecedented level of detail to Flor's model. | |
New Indonesian crayfish species escapes the decor market to become a freedom fighterWith its orange to greenishly orange motley tip, the new crayfish species has been long-confused with its relatives by the tradesmen who have been collecting them for ornamental purposes. Being exported to countries in Europe, East Asia and America C. snowden specimens inevitably landed in the hands of the scientists from Lukhaup's team who eventually recognised and proved them as a new crayfish species. Their research is available in the open-access journal ZooKeys. | |
Brown widow spider reported for the first time in TahitiTahiti is a popular tourist destination, but one unwanted visitor has decided to make its home there: the brown widow spider (Latrodectus geometricus). A paper published in the Journal of Medical Entomology has reported the discovery of the spider for the first time on Tahiti and also on four of the Cook Islands. | |
India floods threaten rare one-horned rhinosHundreds of rare rhinos and other animals are fleeing flooding in India's northeast, raising fears of a rise in poaching during the exodus, a senior wildlife official said Tuesday. | |
Hepatitis A-like virus identified in sealsScientists in the Center for Infection and Immunity at Columbia University's Mailman School of Public Health have discovered a new virus in seals that is the closest known relative of the human hepatitis A virus. The finding provides new clues on the emergence of hepatitis A. The research appears in the July/August issue of mBio, the online open-access journal of the American Society for Microbiology. | |
Deforestation in Mexico butterfly reserve more than triplesIllegal logging more than tripled in the monarch butterfly's wintering grounds In central Mexico, reversing several years of steady improvements, investigators announced Tuesday. | |
Smaller of US panda twins on antibiotics; larger doing wellThe smaller of the two giant panda cubs born over the weekend at the US's Smithsonian National Zoo in Washington is on antibiotics and being bottle-fed, zookeepers said Tuesday. | |
Wildlife veterinarians work with African partners to protect gorillasOnly about 900 mountain gorillas—the animals protected by Dian Fossey of Gorillas in the Mist fame—remain in the wild. But the few will probably "be just fine," largely because veterinary care is now a mainstay in their peaceable kingdom, says Chris Whittier, V97, who has treated gorillas in six national parks in Africa. | |
Ohio zoo sending endangered rhino to Indonesia to mateAn Ohio zoo that has the last Sumatran rhino in the United States announced plans Tuesday to send him to Southeast Asia on a mission to mate and help preserve his critically endangered species. | |
Qatar hails veggie growing trial successDesert nation Qatar will use "cutting-edge technology" to grow up to 70 percent of its own vegetables by 2023—a four-fold increase, officials from Doha's biggest agricultural group said Tuesday. | |
Researchers study tall larkspur toxicity in cattleIn the western foothills and mountain rangelands of the U.S., wild larkspurs (Delphinium spp.) are a major cause of cattle losses. | |
Study in bats and rodents offers insights on how viruses spread across speciesBats are natural reservoirs of several important emerging viruses, and because cross-species transmission appears to be quite common among bats, it's important to study bats in a community context rather than concentrating on individual species. |
