• 06:00 A non-invasive intracellular 'thermometer' with fluorescent proteins has been created

  Read the story at EurekAlert
  A team from the Institute of Photonic Sciences has developed a technique to measure internal cell temperatures without altering their metabolism. This finding could be useful when distinguishing healthy cells from cancerous ones, as well as learning more about cellular processes.

• 06:00 A whale of a discovery: New sensory organ found in rorqual whales

  Read the story at EurekAlert
  Scientists at the University of British Columbia and the Smithsonian Institution have discovered a sensory organ in rorqual whales that coordinates its signature lunge-feeding behavior -- and may help explain their enormous size.

• 06:00 Aggregating instead of stabilizing: New insights into the mechanisms of heart disease

  Read the story at EurekAlert
  Malformed desmin proteins aggregate with intact proteins of the same kind, thereby triggering skeletal and cardiac muscle diseases, the desminopathies. This was discovered by researchers from the RUB Heart and Diabetes Center NRW in Bad Oeynhausen led by PD Dr. Hendrik Milting in an interdisciplinary research project with colleagues from the universities in Karlsruhe, Würzburg and Bielefeld. They report in the Journal of Biological Chemistry.

• 06:00 An introduced bird competitor tips the balance against Hawaiian species

  Read the story at EurekAlert
  Two researchers from the University of Hawaii at Manoa have determined that tens of thousands of native birds have been lost in the Hakalau Forest National Wildlife Refuge, when the Japanese white-eye, a small perching bird originally introduced to Hawaii in 1929 to control insects, increased in numbers. The increase was initiated in a restoration area on the refuge. This study was published in the open access journal NeoBiota.

• 06:00 Anti-inflammatory drugs may improve survival from severe malaria

  Read the story at EurekAlert
  A novel anti-inflammatory drug could help to improve survival in the most severe cases of malaria by preventing the immune system from causing irrevocable brain and tissue damage.Walter and Eliza Hall Institute researchers have shown that a new class of anti-inflammatory agents, called IDR (innate defense regulator) peptides, could help to increase survival from severe clinical malaria when used in combination with antimalarial drugs.

• 06:00 Army study: DNA vaccine and duck eggs protect against hantavirus disease

  Read the story at EurekAlert
  Army scientists and industry collaborators have successfully protected laboratory animals from lethal hantavirus disease using a novel approach that combines DNA vaccines and duck eggs. The work appears in a recent edition of the online scientific journal PLoS ONE, published by the Public Library of Science.

• 06:00 Beetle-infested pine trees contribute more to air pollution and haze in forests

  Read the story at EurekAlert
  The hordes of bark beetles that have bored their way through more than six billion trees in the western US and British Columbia since the 1990s do more than damage and kill pine, spruce and other trees. A new study finds that these pests can make trees release up to 20 times more of the organic substances that foster haze and air pollution in forested areas. It appears in ACS' journal Environmental Science & Technology.

• 06:00 Cardio fitness levels of breast cancer patients may affect survival

  Read the story at EurekAlert
  Women receiving care for breast cancer have significantly impaired cardio-pulmonary function that can persist for years after they have completed treatment, according to a study led by scientists at Duke University Medical Center.

• 06:00 Carnegie Mellon brain research shows visual perception system unconsciously affects our preferences

  Read the story at EurekAlert
  New research from Carnegie Mellon University shows that the brain's visual perception system automatically and unconsciously guides decision-making through valence perception. The findings offer important insights into consumer behavior in ways that traditional consumer marketing focus groups cannot address. For example, asking individuals to react to package designs, ads or logos is ineffective. Instead, companies can use this type of brain science to more effectively assess how unconscious visual valence perception contributes to consumer behavior.

• 06:00 Children's body fat linked to Vitamin D insufficiency in mothers

  Read the story at EurekAlert
  Children are more likely to have more body fat during childhood if their mother has low levels of Vitamin D during pregnancy, according to scientists at the Medical Research Council Lifecourse Epidemiology Unit, University of Southampton.

• 06:00 Common acne medication doubles risk of eye infection

  Read the story at EurekAlert
  Dr. Gabriel Chodick of Tel Aviv University says that acne patients who take oral medications like Accutane double their risk of developing an eye infection compared to those who do not. He says that the use of inexpensive artificial tears or eyedrops, which are available over-the-counter at the local pharmacy, can minimize this eye damage.

• 06:00 Deterring signals: Tobacco plants advertise their defensive readiness to attacking leafhoppers

  Read the story at EurekAlert
  Following herbivory, plants produce jasmonic acid, a hormone which activates several plant defense reactions. Scientists found that leafhoppers can evaluate whether tobacco plants are ready for defense when attacked. If jasmonate-signaling is activated, leafhoppers desist from feeding and test other plants. If the hormonal signaling system is dysfunctional, the herbivores start their attack. In field experiments, the leafhoppers proved as "bloodhounds" to locate plants hidden in natural populations which are naturally defective in jasmonate signaling.

• 06:00 Docs slower to drop 'black box' drugs, adopt new therapies, when access to drug reps is restricted

  Read the story at EurekAlert
  After years of reducing their contact with pharmaceutical sales representatives, physicians now risk an unintended consequence: Doctors who rarely meet with pharmaceutical sales representatives -- or who do not meet with them -- are much slower to drop medicines with the Food and Drug Administration's "black box" warnings and to adopt first-in-class therapies.

• 06:00 Dollars and sense: Why are some people morally against tax?

  Read the story at EurekAlert
  As the US presidential election campaigns heat up, the economic debate is dominated by bailouts, austerity and, inevitably, taxation. Now a new study published in Symbolic Interaction asks why tax is such an important issue to voters and explores the moral ideas which underpin their views.

• 06:00 Efficient and tunable interface for quantum networks

  Read the story at EurekAlert
  Quantum computers may someday revolutionize the information world. But in order for quantum computers at distant locations to communicate with one another, they have to be linked together in a network. While several building blocks for a quantum computer have already been successfully tested in the laboratory, a network requires one additonal component: A reliable interface between computers and information channels. In the current issue of the journal Nature, Austrian physicists report the construction of an efficient and tunable interface for quantum networks.

• 06:00 El Niño weather and climate change threaten survival of baby leatherback sea turtles

  Read the story at EurekAlert
  When critically endangered leatherback turtle hatchlings dig out of their nests, they enter a world filled with threats to survival. Now, Drexel University researchers have found that the climate conditions at the nesting beach affect the early survival of turtle eggs and hatchlings. They predict, based on projections from multiple models, that egg and hatchling survival will drop by half in the next 100 years as a result of global climate change.

• 06:00 Elusive quasiparticles realized

  Read the story at EurekAlert
  In quantum physics physical processes in condensed matter and other many-body systems can often be described with quasiparticles. In Innsbruck, Austria, for the first time Rudolf Grimm's team of physicists has succeeded in experimentally realizing a new quasiparticle - a repulsive polaron - in an ultracold quantum gas. The scientists have published their results in the online edition of the journal Nature.
