After decades of public safety campaigns focused on drinking and driving, it may be time to focus on the seventh leading cause of injury-related death, according to Bureau of Occupational Health and Injury Prevention at New York State Department of Health and Columbia University scholars looking at New York State.
Caring for offspring is unequal between the sexes in many animal species and a new study suggests evolution is the culprit.
Making babies is one of the fundamental conflicts of interest between the sexes. Care by either partner is beneficial to both partners as it increases the health and survival prospects of the common young, while providing care is costly only to the caring individual. As a result, each partner does best in a situation where most of the care is provided by the other partner--an outcome that is clearly impossible.
In 2006, there was a large die-off in bees and though their numbers quickly rebounded and have continued upward since, scientists have been looking for ways to make the periodic collapses that occur less dramatic. The cause the last time it happened was the same plague that bees have endured for as long as science has been able to study them; parasites. But a new study shows that "nature's medicine cabinet" may be able to smooth out those natural booms and busts.
Scientifically engineered tissues intended to repair or regenerate damaged or diseased human tissues require three-dimensional tissue constructs that are densely packed with living cells. The Bio-P3, an innovative instrument able to pick up, transport, and assemble multi-cellular microtissues to form larger tissue constructs is described in an article in Tissue Engineering, Part C: Methods.
A new mathematical analysis tool can numerically describe the skull as an extended network structured in ten modules. Anatomical Network Analysis (AnNA) is based on network analysis mathematical tools for studying anatomy and has led to several studies of both the human skeleton and of the rest of terrestrial vertebrates, especially in regard to the development and evolution of the skull.
Over the long term, a high-fat diet is bad for heart attack risk. Yet a new study finds that if you are going to have a heart attack, you are likely to get through it better if you ate a high-fat diet before it happened. Mice fed a high-fat diet for one day to two weeks days before a heart attack had heart attack reduced by about 50 percent. If the results could be translated to humans, that would mean piling on cheeseburgers and ice cream for a month to a year, not a winning strategy for lots of other reasons.It's another example of the obesity paradox, an unexplained phenomenon where obese patients who do have a heart attack live longer than thin ones.
Researchers at the Medical College of Wisconsin (MCW), in collaboration with other colleagues of the Genetic Epidemiology of Lung Cancer Consortium (GELCC), have identified a gene that is associated with lung cancer.
The findings are published in American Journal of Human Genetics. Through whole exome sequencing, researchers identified a link between a mutation in PARK2, a gene associated with early-onset Parkinson's disease, and familial lung cancer.
The researchers sequenced the exomes (protein coding region of the genome) of individuals from a family with multiple cases of lung cancer. They then studied the PARK2 gene in additional families affected by lung cancer.
For chimpanzees, just like humans, teasing, taunting and bullying are familiar parts of playground politics. An analysis of 12 years of observations of playground fights between young chimpanzees in East Africa finds that chimps with higher-ranked moms are more likely to win.
The results come from an analysis of daily field notes recorded from 2000 to 2011 at Gombe National Park in western Tanzania. Stored in the Jane Goodall Institute Research Center at Duke University and also at The George Washington University, the records are part of a larger database containing more than 50 years of data on over 300 wild chimpanzees, going all the way back to Jane Goodall's first observations from the early 1960s.
It's always helpful to have text or verbal claims about where a video was taken, but when it comes to terrorists or other criminals, they might not be telling the truth. Researchers from Ramón Llull University in Spain have created a system capable of geolocating videos by comparing audiovisual content with a worldwide multimedia database and it is able to locate where the videos were taken with no indication of where they were produced.
Latching onto the probiotics diet fad, several studies have claimed that the gut microbiome, the diverse array of bacteria that live in the stomach and intestines, may be to blame for obesity. But Katherine Pollard, PhD, a senior investigator at the Gladstone Institutes, says it is not that simple.
The Great Lakes have been invaded by more non-native species than any other freshwater ecosystem in the world, and though there have been increasing efforts to stem the tide of invasion threats, they remain vulnerable.
Over the past two centuries, more than 180 non-native species have been recorded in the Great Lakes and the rivers that flow into them. Nearly 20% of these species are considered to be harmful ecologically and economically, posing threats to the Lakes' native biodiversity and multibillion dollar fishery. New threats are emerging because of risks associated with trade in live organisms and climate change,researchers caution in a study in the Journal of Great Lakes Research.
A team of scientists has created a "conjugate" molecule -- one stitched together from two separate molecules -- that seeks out and blocks prostate cancer growth in lab animals.
The molecule NMI combines a near-infrared dye that targets cancer cells and a MAO-A inhibitor often used in antidepressants but recently shown to be effective at reducing or even eliminating prostate tumor growth in mice.

Rivers and streams could be a major source of antibiotic resistance in the environment.
The discovery comes following a study on the Thames river by scientists at the University of Warwick's School of Life Sciences and the University of Exeter Medical School.
The study found that greater numbers of resistant bacteria exist close to some waste water treatment works, and that these plants are likely to be responsible for at least half of the increase observed.
