(Press-News.org) ALLENDALE, Mich. — Even among contemporary U.S. distance runners, men are still much more likely than women to have a competitive orientation, according to researchers at Grand Valley State University in Allendale, Michigan. The findings were published in the online journal, Evolutionary Psychology at http://www.epjournal.net/articles/u-s-masters-track-participation-reveals-a-stable-sex-difference-in-competitiveness/
The new research, led by Robert Deaner, associate professor of psychology at Grand Valley State, shows that, on average, American men participate at track meets about three times as often as American women, and this difference has been consistent since the late 1990s. By contrast, at road races, the sex difference in participation has disappeared.
"The differing pattern of results at track meets and road races is remarkable," said Deaner. "Road races have grown tremendously in popularity in the past few decades but most runners have a recreational orientation, not a competitive one. This is shown in how they answer questionnaires and in their generally slow performances. They run for their mental and physical well-being and to socialize. Track meets are completely different — there aren't medals for every finisher, they haven't become popular, and the runners that do show up almost always run fast.
Deaner said the results are interesting because they support the idea that the disappearance of sex differences in sports motivation in the U.S. is a myth, not reality. Since the passage of Title IX in 1972, girls and women have grown to comprise nearly half of participants in organized high school and collegiate sports. However, little research has tested whether this pattern reflects a decreasing gap in sports motivation.
"When we look more closely at the data, there are still clear indications that some sex differences in sports interest and motivation remain large," said Deaner. "Distance running is a perfect example. Yes, women now participate in road races as much as men do, but our results indicate that the small number of runners who have a competitive orientation are still much more likely to be men."
The new research focused on masters runners, who are defined as being at least 40 years old. Deaner said masters runners were ideal for the study because, unlike many distance runners in high school and college, they aren't motivated by external incentives, such as earning a scholarship.
In Study 1, the researchers assessed participation and the occurrence of relatively fast performances by masters runners at hundreds of road races and track meets in the U.S. Fast performances were defined relative to sex-specific, age-specific world records. Fast performances occurred more than 20 times more often at track meets than at road races. This pattern held for both male and female runners, and it shows that participating at a track meet, but not a road race, is usually a good indicator of having a competitive orientation. Study 1 also found that women comprised 55 percent of participants at road races but only 15 to 28 percent of participants at track meets.
In Study 2, the researchers used data from national championship meets and yearly rankings lists to test whether the sex difference in masters track participation decreased from 1988 to 2012. Across all years, women comprised 27 percent of participants in the national championship meets and 22 percent of those individuals who appeared in the yearly rankings. In both data sets, the sex difference decreased across all 25 years, but only slightly. More crucially, there was no evidence of a decreasing sex difference since the late 1990s.
Deaner acknowledged that the new studies have a major limitation because they are based on patterns of participation, rather than direct measures of motivation. He pointed out, however, that previous studies support their interpretation that there is a sex difference in competitiveness in distance runners.
"We actually have quite a bit of converging evidence. Questionnaire studies find that, although most distance runners in the U.S. do not have a competitive orientation, the ones who do are more likely to be male," said Deaner. "Other studies show that men are roughly three times as likely as women to run fast relative to sex-specific world class standards, and this is likely due, in part, to their greater competitiveness and willingness to maintain large training volumes. Also, we recently published a study demonstrating that there is a robust difference in pacing in the marathon — men are about three times more likely than women to slow down dramatically and this probably reflects men's greater inclination for risk taking, and risk taking is a big part of being competitive.
"The take home message is that this new research complements several other studies in showing that, although men and women are now similar in terms of overall participation in distance running, they still differ, on average, in their motivation. The most exciting aspect of the new research is that we were able to test whether the sex difference has changed over time."

Researchers at the University of California, San Diego School of Medicine have identified a microRNA molecule as a surprisingly crucial player in managing cell survival and growth. The findings, published in the October 7 issue of Cell Metabolism, underscore the emerging recognition that non-coding RNAs – small molecules that are not translated into working proteins – help regulate basic cellular processes and may be key to developing new drugs and therapies.

From AGU's blogs: Detecting avalanches from sounds we can't hear http://blogs.agu.org/geospace/2014/10/07/detecting-avalanches-sounds-cant-hear/
Researchers have developed a new avalanche monitoring method that uses sound below the range of human hearing to detect and track these deadly and destructive snow slides. The technique can detect an avalanche from the moment it starts, picking up the unheard thump of a rupture in the snowpack that can precede the snow cascade. It can then track the avalanche's path second by second down the mountain.

When kids say "the darnedest things," it's often in response to something they heard or saw. This sponge-like learning starts at birth, as infants begin to decipher the social world surrounding them long before they can speak.
Now researchers at the University of Washington have found that children as young as 15 months can detect anger when watching other people's social interactions and then use that emotional information to guide their own behavior.
The study, published in the October/November issue of the journal, Cognitive Development, is the first evidence that ...
LAWRENCE — Scientists have been laboring to detect cancer and a host of other diseases in people using promising new biomarkers called "exosomes." Indeed, Popular Science magazine named exosome-based cancer diagnostics one of the 20 breakthroughs that will shape the world this year. Exosomes could lead to less invasive, earlier detection of cancer, and sharply boost patients' odds of survival.
"Exosomes are minuscule membrane vesicles — or sacs — released from most, if not all, cell types, including cancer cells," said Yong Zeng, assistant professor ...
You're obese, at risk for diabetes and cardiovascular disease, and so motivated to improve your diet that you've enrolled in an intensive behavioral program. But if you need to travel more than a short distance to a store that offers a good selection of healthy food, your success may be limited.
A new study from UMass Medical School and the Massachusetts Department of Public Health finds that not having close access to healthy foods can deter even the most motivated dieters from improving their diet, suggesting that easy access to healthy food is as important as personal ...
Imagine attempting to trace your genetic history using only information from your mother's side. That's what scientists studying the evolution of the red fox had been doing for decades.
Now, University of California, Davis, researchers have for the first time investigated ancestry across the red fox genome, including the Y chromosome, or paternal line. The data, compiled for over 1,000 individuals from all over the world, expose some surprises about the origins, journey and evolution of the red fox, the world's most widely distributed land carnivore.

Typhoon Vongfong strengthened into a Super typhoon on Tuesday, October 7 as NASA's Aqua satellite passed overhead.
On Oct. 7 at 0429 UTC (12:29 a.m. EDT) the Atmospheric Infrared Sounder called AIRS that flies aboard NASA's Aqua satellite captured cloud top temperature data on Super typhoon Vongfong. AIRS data very strong thunderstorms circling Vongfong's clear 27 nautical-mile wide eye. Those cloud top temperatures were colder than -62F/-53C indicating that they were high in the troposphere and capable of generating heavy rainfall. The bands of thunderstorms circling ...
New Swedish research shows that plasmids containing genes that confer resistance to antibiotics can be enriched by very low concentrations of antibiotics and heavy metals. These results strengthen the suspicion that the antibiotic residues and heavy metals (such as arsenic, silver and copper) that are spread in the environment are contributing to the problems of resistance. These findings have now been published in the highly regarded journal mBio.
Antibiotic resistance is a growing medical problem that threatens human health worldwide. Why and how these resistant bacteria ...
PHILADELPHIA — Nearly 60,000 Americans suffer from myasthenia gravis (MG), a non-inherited autoimmune form of muscle weakness. The disease has no cure, and the primary treatments are nonspecific immunosuppressants and inhibitors of the enzyme cholinesterase.
Now, a pair of researchers from the Perelman School of Medicine at the University of Pennsylvania have developed a fast-acting "vaccine" that can reverse the course of the disease in rats, and, they hope, in humans. Jon Lindstrom, PhD, a Trustee Professor in the department of Neuroscience led the study, published ...
A new review of the way health care professionals emphasise weight to define health and wellbeing suggests the approach could be harmful to patients.
Author of the review article, Dr Rachel Calogero of the School of Psychology at the University of Kent, together with experts from other institutions and organisations, recommends that this approach, known as 'weight-normative', is replaced by health care professionals, public health officials and policy-makers with a 'weight-inclusive' approach.
Weight-inclusive approaches, such as the Health At Every Size initiative, ...
