How ants investigate the housing market when searching for their ideal home

2013-10-02
(Press-News.org) Colonies of rock ants (Temnothorax albipennis) need to find ideal homes for the safety and productivity of the queen mother and all of her offspring. They are regularly confronted with the dilemma of whether to move to a better property or remain in their current one, but unlike humans who are susceptible to housing bubbles, ants seem to invest in their housing market in ways that are consistent and rational.

PhD student Carolina Doran and Professor Nigel R. Franks of Bristol's School of Biological Sciences showed experimentally that in order to be ahead of the game, rock ants continually monitor their neighbouring real estate so as to know exactly what new homes are potentially available.

Moreover, their search effort is tuned to the quality of the nest they currently inhabit. They put more effort into finding new homes when they are in a poor one and search less when they are in deluxe accommodation.

Carolina Doran said: "This strategy of adjusting their information gathering according to their actual needs and the real value of higher rungs on the property ladder may help ants to evaluate their housing market in a measured and thorough way that puts many of us to shame."

### The research is published today in the Royal Society Journal Biology Letters.

Mom's weight gain during pregnancy tied to childhood obesity

2013-10-02
Boston, MA - A study of 41,133 mothers and their children in Arkansas has shown that high pregnancy weight gain increases the risk of obesity in those children through age 12. The findings, published Oct. 1 in PLoS Medicine, suggest pregnancy may be an especially important time to prevent obesity in the next generation. "From the public health perspective, excessive weight gain during pregnancy may have a potentially significant influence on propagation of the obesity epidemic," says the study's senior author David S. Ludwig, MD, PhD, director of the New Balance Foundation ...

Decoding sound's source: Mass. Eye and Ear researchers unravel part of the mystery

2013-10-02
BOSTON (Oct. 1, 2013) — As Baby Boomers age, many experience difficulty in hearing and understanding conversations in noisy environments such as restaurants. People who are hearing-impaired and who wear hearing aids or cochlear implants are even more severely impacted. Researchers know that the ability to locate the source of a sound with ease is vital to hear well in these types of situations, but much more information is needed to understand how hearing works to be able to design devices that work better in noisy environment. Researchers from the Eaton-Peabody Laboratories ...

Study led by NYU Langone researchers finds the association between a high body mass index and the risk of death due to cardiovascular disease is stronger among east Asians than south Asians

2013-10-02
(New York City, October 1, 2013)- A study led by researchers at NYU Langone Medical Center and Fred Hutchinson Cancer Research Center has found that the association between body fat and mortality due to cardiovascular disease differs between south and east Asians, a finding that has important implications for global health recommendations. Cardiovascular disease, a condition in which arteries thicken and restrict blood flow, kills more than 17 million people annually, making it the leading cause of death worldwide. In an analysis published today in the British Medical ...

Less can be more when removing lymph nodes during breast cancer surgery

2013-10-02
DALLAS – Oct. 1, 2013 – A conservative approach to removing lymph nodes is associated with less harm for breast cancer patients and often yields the same results as more radical procedures, researchers at UT Southwestern Medical Center have found. In the Oct. 2 edition of the Journal of the American Medical Association, lead author Dr. Roshni Rao, associate professor of surgery at UT Southwestern, and other investigators from the Harold C. Simmons Cancer Center reviewed studies on patient outcomes of women who had received various forms of surgical treatment, ranging ...

New fossils push the origin of flowering plants back by 100 million years to the early Triassic

2013-10-02
Flowering plants evolved from extinct plants related to conifers, ginkgos, cycads, and seed ferns. The oldest known fossils from flowering plants are pollen grains. These are small, robust and numerous and therefore fossilize more easily than leaves and flowers. An uninterrupted sequence of fossilized pollen from flowers begins in the Early Cretaceous, approximately 140 million years ago, and it is generally assumed that flowering plants first evolved around that time. But the present study documents flowering plant-like pollen that is 100 million years older, implying ...

Over-the counter as effective as Rx at managing post-tonsillectomy pain

2013-10-02
DETROIT -- You may be able to eat all of the ice cream you want after having your tonsils removed, but researchers at Henry Ford Hospital in Detroit say you don't necessarily need a prescription to reduce post-operative pain -- an over-the-counter pain-reliever is just as effective. The study shows over-the-counter ibuprofen manages pain after a tonsillectomy for children and adults as well as the prescription pain medications acetaminophen with hydrocodone and acetaminophen with codeine, which is no longer recommended for use in children. "Based on this study and ...

Smoking during pregnancy may increase risk of bipolar disorder in offspring

2013-10-02
A study published today in the American Journal of Psychiatry suggests an association between smoking during pregnancy and increased risk for developing bipolar disorder (BD) in adult children. Researchers at the New York State Psychiatric Institute and the Department of Epidemiology at the Mailman School of Public Health at Columbia University, in collaboration with scientists at the Kaiser Permanente Division of Research in Oakland, California, evaluated offspring from a large cohort of pregnant women who participated in the Child Health and Development Study (CHDS) ...

Researchers bring product testing to foster care system

2013-10-02
Ever since cruise lines first began building mock suites for passengers to try out before installing the rooms on ocean liners in the 1940s, businesses have been devising trial runs for a small number of consumers to test merchandise prior to mass production. Today, companies still make important changes based on this "usability testing" before taking their goods to the wider market, and researchers now say that what works for cell phones and video games may also work for human services. Karen Blase, senior scientist at UNC's Frank Porter Graham Child Development Institute, ...

Researchers identify traffic cop for meiosis--with implications for fertility and birth defects

2013-10-02
Researchers at New York University and the Whitehead Institute for Biomedical Research have identified the mechanism that plays "traffic cop" in meiosis—the process of cell division required in reproduction. Their findings, which appear in the journal eLife, shed new light on fertility and may lead to greater understanding of the factors that lead to birth defects. "We have isolated a checkpoint that is necessary for a genome's viability and for normal development," said Andreas Hochwagen, an assistant professor in NYU's Department of Biology, who co-authored the paper ...

'Walking droplets'

2013-10-02
VIDEO: A droplet of silicone oil bounces in place on a vibrating fluid bath. Click here for more information. WASHINGTON, D.C. Oct. 1, 2013 -- A research team led by Yves Couder at the Université Paris Diderot recently discovered that it's possible to make a tiny fluid droplet levitate on the surface of a vibrating bath, walking or bouncing across, propelled by its own wave field. Surprisingly, these walking droplets exhibit certain features previously thought to be exclusive to ...
