Ever since he can remember, Karl Jones has been fascinated by the animals that live in streams. 'I grew up next to a river in the Adelaide Hills where I spent many hours catching the creatures that live there', he recalls; and one group of aquatic insects that caught his eye was the backswimmers. However, two members of the Family (Anisops and Buenoa) have an even more remarkable talent: they can swim at depths that other backswimmers can only reach fleetingly.

GRAND RAPIDS, Mich. -- A Grand Valley State University nursing faculty member will present research at a national conference about text messaging to promote medication adherence trials and an interprofessional approach to helping vulnerable older adults remain at home and out of nursing homes.
Sandra Spoelstra, associate dean for research and scholarship for the Kirkhof College of Nursing, will give two presentations at the Gerontological Society of America Annual Scientific Meeting in Florida November 18 and 20.

Aurora, Colo. (Nov. 4, 2015) - New results from the Treatment Options for Type 2 Diabetes in Youth study (TODAY) examined predictors of the outcomes in youth with onset type 2 diabetes (T2D) based on early characteristics at diagnosis, and suggests the need for specific criteria for adolescents that are different from those in adults.
Swimming, walking and other mild physical activities, along with avoidance of resistance exercise, are often recommended for pregnant women. But a new PhD thesis at Sahlgrenska Academy has found that resistance exercise can relieve symptoms related to pregnancy and improve sense of control.
Recommendations for the intensity, duration and type of exercise during pregnancy vary widely. Most previous research has focused on the effects of aerobics and few have explored resistance exercise.
Suitable exercise
In a study of 26 twin and sibling pairs where one of each pair had received long-term antiepileptic drug therapy, participants who were taking these medications swayed more during static and dynamic balance tests compared with their siblings who were not taking antiepileptic medications. They also showed a greater deterioration in sway tests over an average interval of 3 years.
Addressing these balance issues in patients taking antiepileptic drugs may help reduce their risk of falling, which can lead to fractures and other injuries.
WASHINGTON, D.C, November 4, 2015 -- It's well known that gradual adaptation to the environment shaped the development of human bodies and brains, but recent work by an international group of researchers suggests that the variations in human linguistic evolution also reflect adaptations to the local ecological conditions.
Iron selenide (FeSe) is an attracting superconducting material since the superconducting transition temperature (Tc) is enhanced from 8 K in bulk form toward 65 K in one-monolayer form.
However, systematic thickness dependence of electrical measurement has been difficult to address.
A team of researchers at Tohoku University's Institute for Materials Research (IMR), has realized layer-by-layer etching in superconducting FeSe films down to approximately one-monolayer about 0.6 nm using classical electrochemical reaction in electric-double-layer transistor configuration.
A link between depression in pregnancy and long periods of sitting down has been identified by researchers from the University of Warwick.
The study found those suffering from symptoms of depression during pregnancy are more likely to sit down for long periods of time in the second trimester. The academics also found this puts them at risk of greater weight gain and contracting gestational diabetes.
A team of researchers at Northeastern University has developed an innovative 3-D printing technology that uses magnetic fields to shape composite materials--mixes of plastics and ceramics--into patient-specific products. The biomedical devices they are developing will be both stronger and lighter than current models and, with their customized design, ensure an appropriate fit. Their paper on the new technology appears in the Oct. 23 issue of Nature Communications.
URBANA, Ill. - It may come as a surprise that, even after the Great Recession ended in 2009, almost 50 million people in the United States are food insecure -- that is, they lack access to adequate food because of limited money or other resources. University of Illinois economist Craig Gundersen and University of Kentucky's James Ziliak examined recent research on food insecurity and its association with poor health and offer suggestions, including that doctors screen for hunger.
In a meta-analysis of randomized clinical trials for the treatment of acute ischemic stroke, an endovascular intervention (such as use of a very small catheter to remove a blood clot) compared to standard medical care (administration of a clot dissolving agent) was associated with improved functional outcomes and higher rates of functional independence at 90 days, but no significant difference in symptomatic intracranial hemorrhage (bleeding in the brain) or all-cause mortality, according to a study in the November 3 issue of JAMA.
Although the absolute risk was low, researchers found an increased risk of childhood-onset epilepsy among children in Denmark who had a hospital-diagnosed pertussis infection, compared with the general population, according to a study in the November 3 issue of JAMA.
Scientists have good news for patients who suffer from currently untreatable dry age-related macular degeneration (dry AMD). In a new study, researchers identified a potential target for future therapies to slow the progression of the blinding condition. Published in Investigative Ophthalmology & Visual Science (IOVS), the findings indicate that treatments currently used for other conditions could also work for dry AMD.
Over the past three decades, China has seen a significant migration of its population from rural areas to cities. During the same time period, poor air quality and other environmental problems in urban China have gained increased attention. Now, a University of Missouri researcher has found a strong correlation between the influx of labor migrants from rural to urban areas and negative environmental effects on those destination cities.
A continuing look at a Maya village in El Salvador frozen in time by a blanket of volcanic ash 1,400 years ago shows the farming families who lived there went about their daily lives with virtually no strong-arming by the elite royalty lording over the valley.
