• 06:00 'ROCK' off: Study establishes molecular link between genetic defect and heart malformation

  Read the story at EurekAlert
  UNC researchers have discovered how the genetic defect underlying one of the most common congenital heart diseases keeps the critical organ from developing properly. According to the new research, mutations in a gene called SHP-2 distort the shape of cardiac muscle cells so they are unable to form a fully functioning heart. The study also shows that treatment with a drug that regulates cell shape rescues the cardiac defect.

• 06:00 3 'targeted' cancer drugs raise risk of fatal side effects

  Read the story at EurekAlert
  Treatment with three "targeted" cancer drugs has been linked to a slightly elevated chance of fatal side effects, according to a new analysis led by scientists at Dana-Farber Cancer Institute. The risk for the fatal side effects remains low, but they should be factored in when developing patients' treatment plans.

• 06:00 A bug's (sex) life: Diving beetles offer unexpected clues about sexual selection

  Read the story at EurekAlert
  Studies of diving beetles suggest sperm evolution may be driven by changes in female reproductive organs, challenging the paradigm of post-mating sexual selection being driven mostly by competition among sperm. In the process, the researchers discovered an unexpected and stunning variety of sperm form and behavior.

• 06:00 A new species of bamboo-feeding plant lice found in Costa Rica

  Read the story at EurekAlert
  Several periods of field work during 2008 have led to the discovery of a new species of bamboo-feeding plant lice in Costa Rica's high-altitude region Cerro de la Muerte. The discovery was made thanks to molecular data analysis of mitochondrial DNA. The collected records have also increased the overall knowledge of plant lice (one of the most dangerous agricultural pests worldwide) from the region with more that 20 percent. The study was published in the open-access journal ZooKeys.

• 06:00 Antidepressant-suicide link in youths absent in new analysis

  Read the story at EurekAlert
  In 2004, concerns about antidepressant drugs increasing suicidal thoughts and behaviors in young patients prompted the FDA to issue a rare "black box warning." Now, a new analysis of clinical trial data finds that treatment with the antidepressant fluoxetine did not increase -- or decrease -- suicidality in children compared to placebo treatment.

• 06:00 Cognitive problems common among non-demented elderly

  Read the story at EurekAlert
  Both subjective and objective cognitive impairment are highly common among non-demented elderly Swedes, with an overall prevalence of 39 percent and 25 percent respectively, according to a nationwide twin study by researchers at the Aging Research Center of Karolinska Institutet, Sweden. The study confirms higher education as a major protective factor and stresses the importance of environmental aspects over genes in mild cognitive disorders in old age.

• 06:00 Combined asthma medication therapy shown to reduce attacks

  Read the story at EurekAlert
  A Henry Ford Hospital study has found that using two types of common asthma medications in combination reduces severe asthma attacks.Researchers say using long-acting beta-agonists in fixed-dose combination with inhaled corticosteroid (ICS) appear to reduce asthma attacks as well as or better than corticosteroids alone. Patient groups who had in greatest benefits were patients 18 and older, African-American patients, male patients, and patients with moderate to severe asthma.

• 06:00 Copper + love chemical = big sulfur stink

  Read the story at EurekAlert
  When Hiroaki Matsunami, Ph.D., at Duke set out to study a chemical in male mouse urine called MTMT that attracts female mice, he didn't think he would stumble into a new field of study. But the research has led scientists at Duke University Medical Center and the University of Albany to the discovery that it's the copper in our bodies that makes mammals recoil from sulfur chemical smells.

• 06:00 Does online dating really work?

  Read the story at EurekAlert
  Whether enlisting the help of a grandmother or a friend or the magic of Cupid, singles long have understood that assistance may be required to meet someone special. Today such help is likely to come from online methods of matchmaking. But online dating, according to new Northwestern University research, depends largely on ineffective algorithms and profiles for finding potential love interests. Mobile dating, the latest iteration in digital dating, however, may hold the most promise.

• 06:00 Domestic cats, and wild bobcats and pumas, living in same area have same diseases

  Read the story at EurekAlert
  The joint National Science Foundation and National Institutes of Health Ecology and Evolution of Infectious Diseases Program funded the study. Scientists at Colorado State University and other institutions conducted the research. It provides evidence that domestic cats and wild cats that share the same outdoor areas in urban environments also can share diseases such as Bartonellosis and Toxoplasmosis. Both can be spread from cats to people.

  Read the story at EurekAlert
  The love song of an extinct cricket that lived 165 million years ago has been brought back to life by scientists at the University of Bristol. The song - possibly the most ancient known musical song documented to date - was reconstructed from microscopic wing features on a fossil discovered in North East China. It allows us to listen to one of the sounds that would have been heard by dinosaurs and other creatures roaming Jurassic forests at night.
