Invertebrate numbers nearly halve as human population doubles

Invertebrate numbers have decreased by 45% on average over a 35 year period in which the human population doubled, reports a study on the impact of humans on declining animal numbers.

This decline matters because of the enormous benefits invertebrates such as insects, spiders, crustaceans, slugs and worms bring to our day-to-day lives, including pollination and pest control for crops, decomposition for nutrient cycling, water filtration and human health. (more…)

MU Researchers Try to Better Predict Storms that Produce Deadly Flash Flooding

Weather phenomenon triggers intense rainfall that leads to flash floods

COLUMBIA, Mo. – According to the National Weather Service, more than 125 people die from flash floods every year. Flash floods often arise from a weather phenomenon known as an “elevated convection,” which causes intense thunderstorms that lead to flash flooding. However, scientists do not have a strong understanding of what causes these elevated storms. A team of researchers at the University of Missouri will deploy to eastern Kansas and western Missouri to study this phenomenon throughout the spring. (more…)

NASA: Warm Rivers Play Role in Arctic Sea Ice Melt

The heat from warm river waters draining into the Arctic Ocean is contributing to the melting of Arctic sea ice each summer, a new NASA study finds.

A research team led by Son Nghiem of NASA’s Jet Propulsion Laboratory in Pasadena, Calif., used satellite data to measure the surface temperature of the waters discharging from a Canadian river into the icy Beaufort Sea during the summer of 2012. They observed a sudden influx of warm river waters into the sea that rapidly warmed the surface layers of the ocean, enhancing the melting of sea ice. A paper describing the study is now published online in the journal Geophysical Research Letters. (more…)

Climate change won’t reduce winter deaths

Climate change is unlikely to reduce the UK’s excess winter death rate as previously thought. A new study, published in Nature Climate Change, debunks the widely held view that warmer winters will cut the number of deaths normally seen at the coldest time of year.

Analysing data from the past 60 years, researchers at UCL and the University of Exeter looked at how the winter death rate has changed over time, and what factors influenced it. (more…)

UA anthropologist Susan J. Shaw and UA pharmacist Jeannie Lee have been awarded $1.48 million from the NIH to study medication adherence and health literacy.

UA associate professor of anthropology Susan J. Shaw and UA assistant professor of pharmacy Jeannie Lee have received $1.48 million from the National Institutes of Health to study factors that impact medication adherence among residents in Massachusetts, where state law mandated that nearly every resident receive a minimum level of health care insurance coverage.

HIV meds dialogue differs by race, ethnicity

Researchers found specific racial/ethnic differences in discussions of HIV medicine adherence in a newly published analysis of recorded office visits between 45 doctors and nurse practitioners and more than 400 patients.

PROVIDENCE, R.I. [Brown University] — A lot of evidence shows that a patients’ race or ethnicity is associated with differences in how health care providers communicate with them, the health care they receive, and their health outcomes. In HIV care, a key to those outcomes is whether people take their medications as prescribed. A new study of the doctor-patient dialogue about HIV drug adherence found several specific differences in those conversations depending on patients’ race and ethnicity. (more…)

Online Design: Novel Collaborative Software Helps Systems Engineers Link Performance and Cost

Today’s modeling and simulation (M&S) software provides indispensible tools for systems engineering challenges. Such programs allow investigators to experiment with “what-ifs” by adjusting design parameters and examining potential outcomes.

A team from the Georgia Tech Research Institute (GTRI) has produced an advanced web-based tool that lets physically separated participants collaborate on model-based systems engineering projects. Known as the Framework for Assessing Cost and Technology (FACT), the program utilizes open-source software components to allow users to visualize a system’s potential expense alongside its performance, reliability and other factors.

People who enjoy life maintain better physical function in their daily activities and keep up faster walking speeds as they age, compared with people who enjoy life less, according to a new study led by Professor Andrew Steptoe (UCL Epidemiology & Public Health).

The research, published in CMAJ (Canadian Medical Association Journal), was based on data from the English Longitudinal Study of Ageing (ELSA). It followed 3,199 men and women aged 60+ in England over an eight year period in order to examine the link between positive well-being and physical well-being. (more…)
