There is no single sexy chin. That's the conclusion of a new Dartmouth College global study of male and female preferences for facial characteristics of the opposite sex. The results, which contradict the notion that human beauty is universal, are published in the journal PLOS ONE. The researchers studied chin shapes among 180 male and female skeletons in nine areas in Australia, Africa, Asia, and Europe to test the universal facial attractiveness hypothesis. The hypothesis proposes that some facial features are universally preferred by the opposite sex because they ...

New Rochelle, NY, April 9, 2013—One of the main obstacles that stands in the way of using human hematopoietic stem cells (hHSCs) to treat a variety of diseases is the difficulty growing them in culture—they quickly die or differentiate into other cell types. A series of experiments that demonstrate the successful use of fat cells as part of a feeder layer to support prolonged growth of hHSCs in culture is reported in an article in BioResearch Open Access, a bimonthly peer-reviewed open access journal from Mary Ann Liebert, Inc., publishers. The article is available on the ...

Scientists from UCLA's Fielding School of Public Health led by Julia Heck, an assistant researcher in the school's epidemiology department and a member of UCLA's Jonsson Comprehensive Cancer Center, have found a possible link between exposure to traffic-related air pollution and several childhood cancers. The results of their study — the first to examine air pollution from traffic and a number of rarer childhood cancers — were presented on April 9 in an abstract at the annual meeting of the American Association for Cancer Research in Washington, D.C. For the study, ...

ANN ARBOR—In a development that could make the advanced form of secure communications known as quantum cryptography more practical, University of Michigan researchers have demonstrated a simpler, more efficient single-photon emitter that can be made using traditional semiconductor processing techniques. Single-photon emitters release one particle of light, or photon, at a time, as opposed to devices like lasers that release a stream of them. Single-photon emitters are essential for quantum cryptography, which keeps secrets safe by taking advantage of the so-called observer ...

According to a new study published online in the Journal of the American College of Radiology, any efficiencies in physician interpretation and diagnosis gained when different providers interpret different medical imaging scans performed on the same patient are minute and vary by procedure. Specifically, no potential intra-service work duplication was found when different exam interpretations were rendered by different physicians in the same group practice. Small potential efficiencies were found possible regarding pre- and post-service activities. Across all modalities ...

BOSTON (April 9, 2013) — Medical school graduates entering one family medicine residency program might receive training that is markedly different than another family medicine residency program. While these new medical school graduates, called residents, will gain the clinical knowledge needed to practice medicine, their scope of skills depend on their specific experiences as residents. A team of healthcare professionals from the Family Medicine Residency Program at Tufts University School of Medicine have published a paper in the Journal of Graduate Medical Education that ...

ROCHESTER, Minn. -- In a first-of-its-kind study, researchers from the United States and Europe discovered genetic mutations associated with long QT syndrome (LQTS), a genetic abnormality in the heart's electrical system, in a small number of intrauterine fetal deaths, according to a study in the April 10 issue of the Journal of the American Medical Association. Researchers conducted a molecular genetic evaluation (referred to as a postmortem cardiac channel molecular autopsy) in 91 cases of unexplained fetal death (stillbirths) from 2006-2012. They discovered the prevalence ...

Field trials and genetic studies have shown that a new variety of broccoli reliably yields higher levels of a health-promoting compound. Broccoli contains a compound called glucoraphanin, which has been shown to promote health by maintaining cardiovascular health and a reduction in the risk of cancer. A long term breeding programme to increase glucoraphanin levels has resulted in the commercial release of Beneforté broccoli. Beneforté was developed by crossing standard broccoli with a wild relative derived from Sicily. Publicly funded research to develop Beneforté broccoli ...

Johns Hopkins scientists have created a free, Web-based tool to help patients decide whether it's best to accept an immediately available, but less-than-ideal deceased donor kidney for transplant, or wait for a healthier one in the future. Historically, the researchers say, it has been difficult, if not impossible, to accurately quantify the risk of accepting a deceased-donor kidney that may have been infected by hepatitis C, as compared to waiting what could be months or years for a better organ. There is a 5 to 15 percent chance of dying every year on the waiting list. ...

Tumbling in the waves as they hit a rocky shore tells purple sea urchin larvae it's time to settle down and look for a spot to grow into an adult, researchers at the University of California, Davis, Bodega Marine Laboratory have found. The work is published April 8 in the journal Proceedings of the National Academy of Sciences. "How these animals find their way to the right habitat is a fascinating problem," said Brian Gaylord, professor of evolution and ecology at UC Davis and a researcher at the Bodega Marine Lab. "The turbulence response allows them to tell that they're ...

Researchers at Moffitt Cancer Center and colleagues at the University of South Florida have found that when given together, a two-drug combination acts synergistically in test animals modeled with sarcoma tumors. They report that the drug combination of MK-1775 and gemcitabine resulted in a 70 percent decrease in the tumor volume when compared to receiving one drug or the other. Their study was published in the March 8 online edition of PLOS ONE. "Sarcomas are rare tumors affecting both children and adults, but sarcomas account for a greater number of pediatric cancers ...

ATLANTA – A potential new strategy to developing new drugs to control inflammation without serious side effects has been found by Georgia State University researchers and international colleagues. Jian-Dong Li, director of Georgia State's Center for Inflammation, Immunity and Infection, and his team discovered that blocking a certain pathway involved in the biological process of inflammation will suppress it. Inhibiting a molecule called phosphodiesterase 4B, or PDE4B, suppresses inflammation by affecting a key gene called CLYD, a gene that serves as a brake on inflammation. The ...

MADISON – The age at which a child with autism is diagnosed is related to the particular suite of behavioral symptoms he or she exhibits, new research from the University of Wisconsin–Madison shows. Certain diagnostic features, including poor nonverbal communication and repetitive behaviors, were associated with earlier identification of an autism spectrum disorder, according to a study in the April issue of the Journal of the American Academy of Child and Adolescent Psychiatry. Displaying more behavioral features was also associated with earlier diagnosis. "Early ...

PROVIDENCE, R.I. – A study at Rhode Island Hospital has found that despite complications, patients co-infected with the pandemic 2009-2010 influenza A H1N1 (pH1N1) and a second respiratory virus were not associated with worse outcomes or admission to the hospital's intensive care unit. The study is published online in the journal PLOS ONE. "There is scant data in the literature regarding the incidence and impact of simultaneous infection by two respiratory viruses, particularly in adults," said senior investigator Leonard Mermel, D.O., medical director of the department ...

Multiple genes contribute to risk for schizophrenia and appear to function in pathways related to transmission of signals in the brain and immunity, according to an international study led by Virginia Commonwealth University School of Pharmacy researchers. By better understanding the molecular and biological mechanisms involved with schizophrenia, scientists hope to use this new genetic information to one day develop and design drugs that are more efficacious and have fewer side effects. In a study published online in the April issue of JAMA Psychiatry, the JAMA Network ...

A Johns Hopkins Children's Center survey of 102 clinicians who treat teenage girls with pelvic inflammatory disease (PID) has found that official guidelines designed to inform decisions about hospitalization versus outpatient care leave some clinicians scratching their heads. The study, conducted by a team of adolescent medicine specialists and published online in the journal Sexually Transmitted Diseases, presented the clinicians with a series of common clinical scenarios and discovered a great deal of uncertainty among some trying to choose between inpatient and outpatient ...

SALT LAKE CITY, April 10, 2013 – University of Utah researchers developed a high-speed camera system that spent the past two winters photographing snowflakes in 3-D as they fell – and they don't look much like those perfect-but-rare snowflakes often seen in photos. "Until our device, there was no good instrument for automatically photographing the shapes and sizes of snowflakes in free-fall," says Tim Garrett, an associate professor of atmospheric sciences. "We are photographing these snowflakes completely untouched by any device, as they exist naturally in the air." Snowflakes ...

New research suggests that patients with knee osteoarthritis (OA) who wear flat, flexible footwear (mobility shoes) had significant reduction in knee loading—the force placed upon the joint during daily activities. Results published in Arthritis & Rheumatism, a journal of the American College of Rheumatology (ACR), show that long term use of the mobility shoes helped OA patients adapt their gait, or how they walk, which improved knee loading, even when the mobility shoes were no longer worn. More than 27 million Americans over the age of 25 have some form of OA, which ...
