Snow found he needed a two-step process for the modern hands to successfully differentiate men from women. He first measured the overall size of the hand using five different measurements. This separated the adult male hands from the rest. Snow found that step one was 79 percent successful in determining sex, but adolescent males were classified as female.

COLUMBIA, Mo. -- Many American diets fall short of meeting nutritional guidelines resulting in burgeoning obesity rates and health problems across the nation. Statistics show that most Americans consume only half of the daily recommended amount of dietary fiber. Now, a research team at the University of Missouri is addressing the fiber deficit by including citrus fiber in ground beef while retaining the quality and taste of the meat.
Shoppers are more likely to buy a product from a different location when a pleasant sound coming from a particular direction draws attention to the item, according to a new study in the Journal of Consumer Research.
Contrary to public perception, "glassing" incidents, particularly at licensed venues, constitute a relatively small proportion of all alcohol-related violence.
This Early View paper is written by paramedic student Anthony Laing, Dr Marguerite Sendall who is a lecturer in health promotion and qualitative research at the Queensland University of Technology, and emergency paediatrician Dr Ruth Barker from the Mater Children's Hospital in Brisbane and director of the Queensland Injury Surveillance Unit.
Unfortunately, most cave art photographs lack size indication, making it difficult to determine relative size and the sex of the artist. Snow visited a number of caves and the few existing images with size indications. He also collected hand images from people with European and Mediterranean ancestry. He published his results in the current issue of American Antiquity.
Have you ever wondered why young children can eat bags of Halloween candy and feel fine the next day – compared to adults who experience all sorts of agony following the same junk food binge? Evolution and a gene called Foxo may be to blame. Working in fruit flies, scientists at the Buck Institute have identified a mechanism that helps the flies adapt to changes in diet when they're young; they've discovered that same mechanism gets misregulated as the flies age, disrupting metabolic homeostasis, or balance.
The explosion in music consumption over the last century has made 'what you listen to' an important personality construct – as well as the root of many social and cultural tribes – and, for many people, their self-perception is closely associated with musical preference. We would perhaps be reluctant to admit that our taste in music alters - softens even - as we get older.
Providence, RI -- During the "New Math" movement of the 1960s, a team of mathematicians developed a new structure for elementary mathematics. Instead of having a single subject, namely, school arithmetic, as its central core, this new structure instead had eight "strands" that were supposed to tie together elementary mathematics content. The strands structure has persisted to this day. In an article in the November 2013 issue of the Notices of the American Mathematical Society, Liping Ma argues that the strands structure has significantly weakened U.S. school mathematics.
Nyon, Switzerland (October 14, 2013) – A new report published today by the International Osteoporosis Foundation (IOF) warns that as a result of ageing populations and osteoporosis not being treated as a priority, health care providers will be faced with an avalanche of fractures and rising costs.
Approximately 22 million women and 5.5 million men in 27 member states of the European Union (EU27)*, have osteoporosis; the total burden is expected to increase to 33.9 million (increase of 23 per cent) by 2025.
Neurosurgical resident–led effort to improve quality and reduce costs in a leading academic institutionCharlottesville, VA (October 15, 2013). An incentive program to reduce the number of unnecessary diagnostic laboratory tests performed in neurosurgical patients at UC San Francisco (UCSF) was highly successful. Resident trainees in neurosurgery identified five frequently scheduled laboratory tests that rarely yield information that would change patient care. A new set of guidelines was developed to determine when these tests should be performed.
Villi are small epithelial protrusions that serve to increase the surface area of the gut for efficient nutrient absorption. The mechanism of their formation during development was recently revealed by a study published in Science. The investigations, carried out by two research groups at Harvard University, were complemented by computational modelling carried out at the University of Jyväskylä and funded by the Academy of Finland.
DETROIT – Emergency Departments across Michigan are better prepared to handle a disaster today than they were seven years ago, according to a Henry Ford Hospital study.
The study found that 84 percent of emergency departments said they are more prepared to handle a terrorist attack or natural disaster than they were in 2005.
They've also enhanced their preparedness efforts by adding decontamination rooms, stockpiling antidotes for nerve gas and cyanide, and storing more respiratory protection supplies.
Chicago, October 14, 2013—The Associated Press-NORC Center for Public Affairs Research has released the results of a major new survey exploring the views of older Americans about their plans for work and retirement. It provides in-depth information about a rapidly growing segment of the population that by choice or circumstance is working longer. The Great Recession has had a marked impact on retirement plans.
PORTLAND, Ore. — A research team led by Oregon Health & Science University (OHSU) and the University of California, Davis, reveals that childhood gunshot injuries, while uncommon, are more severe, require more major surgery, have greater mortality and higher per-patient costs than any other mechanism for childhood injury – particularly among adolescent males. The study is published online in the journal Pediatrics.
In a study, published online today in the journal Age and Ageing, of over 270 patients newly diagnosed with minor strokes or transient ischaemic attack (TIA), only a minority sought medical help within the timeframe recommended by the Royal College of Physicians. This is despite the high profile FAST campaign, which was taking place at the time that the study was conducted.
