Gal-pagos reptiles living near human settlements harbor antibiotic-resistant bacteria

Land and marine iguanas and giant tortoises living close to human settlements or tourist sites in the Gal-pagos islands are more likely to harbor antibiotic-resistant bacteria than those living in more remote or protected sites on the islands, researchers report in a new study.

Study explores global rise of monogamous marriage as a dominant cultural institution

In cultures that permit men to take multiple wives, the intra-sexual competition that occurs causes greater levels of crime, violence, poverty and gender inequality than in societies that institutionalize and practice monogamous marriage.

First genome-wide study of high-altitude adaptations in Ethiopians

Over many generations, people living in the high-altitude regions of the Andes or on the Tibetan Plateau have adapted to life in low-oxygen conditions. Living with such a distinct and powerful selective pressure has made these populations a textbook example of evolution in action, but exactly how their genes convey a survival advantage remains an open question. Now, a University of Pennsylvania team has made new inroads to answering this question with the first genome-wide study of high-altitude adaptations within the third major population to possess them: the Amhara people of the Ethiopian Highlands.

Distal-less gene plays a critical role in development of fruit fly olfactory system

Fruit flies don't have noses, but a huge part of their brains is dedicated to processing smells. Flies probably rely on the sense of smell more than any other sense for essential activities such as finding mates and avoiding danger. UW-Madison researchers have discovered that a gene called distal-less is critical to the fly's ability to receive, process and respond to smells.

GSA honors researchers, educators for distinguished service in the field of genetics

The Genetics Society of America (GSA) is pleased to announce the 2012 recipients of its five awards for distinguished service in the field of genetics. The recipients of these awards were nominated and selected by their colleagues.

Totally drug resistant Tuberculosis hits India

Reports reveal that nearly a dozen people in India are infected with a type of tuberculosis that is resistant to all antibiotics used to treat the disease and is thus named “totally drug resistant” or TDR tuberculosis.

BJALCF receives $1 million in grants for 2012 Lung Cancer Research

Just two months shy of marking its 7-year anniversary, BJALCF announced today that it has awarded over $1 million in grants for 2012 Lung Cancer Research. BJALCF has made a promise to the Lung Cancer Community to fund only immediate results-oriented projects or programs promising to catalyze progress through early detection, genetic testing, drug discovery and patient-focused outcomes.

Seashell study can aid understanding of ancient nervous systems

Determining the evolution of pigmentation patterns on mollusk seashells-which could aid in the understanding of ancient nervous systems-has proved to be a challenging feat for researchers. Now, however, through mathematical equations and simulations, University of Pittsburgh and University of California, Berkeley, researchers have used 19 different species of the predatory sea snail Conus to generate a model of the pigmentation patterns of mollusk shells.

Chemotherapy drugs can lead to relapse of leukemia

The chemotherapy drugs required to push a common form of adult leukemia into remission may contribute to DNA damage that can lead to a relapse of the disease in some patients, findings of a new study suggest.

Disruption of circadian rhythms cause accelerated neurodegeneration and premature death

New research at Oregon State University provides evidence for the first time that disruption of circadian rhythms - the biological "clocks" found in many animals - can clearly cause accelerated neurodegeneration, loss of motor function and premature death.

UCLA researchers identify chemical changes in brains of patients with early-onset Alzheimer's

With a lack of effective treatments for Alzheimer's, most of us would think long and hard about whether we wanted to know years in advance if we were genetically predisposed to develop the disease. For researchers, however, such knowledge is a window into Alzheimer's disease's evolution.

Cardiologist measures risk factors associated with CR

The cardiologist Aitor Jim-nez has managed to gather and characterise in detail 110 cases of cardiac rupture (CR), after spending 22 years (1978-2000) gathering data at the Hospital de Cruces, near Bilbao. It is one of the broadest anatomical series described in this respect. CR is the most serious complication of acute myocardial infarction; it is not very common, but when it does occur, it is mortal in practically all cases. So prevention, although difficult, seems more feasible than cure.

NYU medical students use online 3D interactive virtual human body

First-year students at NYU School of Medicine were introduced to a pioneering online 3D interactive virtual human body called the BioDigital Human. This unique educational experience supplements the traditional use of human cadavers in anatomy instruction by allowing students to both view and interact with realistically simulated 3D organs and other anatomical structures.

Analysis and examination: Detailing the records, evolution of GOP presidential primary candidates

Media outlets report on what Rick Santorum did after he left the Senate and what he would have on his to-do list if elected, the continuing "risks" Mitt Romney faces from the left and the right, and on an ethics group that is directing a challenge at Newt Gingrich.

Researchers discover that flatworm lacks centrosome

A tiny, freshwater flatworm found in ponds and rivers around the world that has long intrigued scientists for its remarkable ability to regenerate has now added a new wrinkle to biology.

MTR technique indicates that COPAXONE therapy results in tissue repair in RRMS patients

Researchers utilizing an advanced magnetic resonance imaging (MRI) technology to characterize and chart the evolution of MS lesions found that relapsing-remitting multiple sclerosis (RRMS) patients treated with COPAXONE (glatiramer acetate injection) experienced significantly increased magnetization transfer ratio.

Scientists show how HCV virus hijacks miR-122 in liver cells

Viral diseases are still one of the biggest challenges to medical science. Thanks to thousands of years of co-evolution with humans, their ability to harness the biology of their human hosts to survive and thrive makes them very difficult to target with medical treatment.

Chimps, like humans, inform ignorant group members of danger

It's a basic rule of effective communication: Consider your audience. According to a new report published online on December 29 in Current Biology, a Cell Press publication, that rule of thumb is not lost on wild chimpanzees. Chimps are more likely to make an alarm call about the presence of a snake when others in the group are unaware of the apparent danger they face, the new evidence shows.
