Research presented at the ASM Microbe 2017 meeting by Bryan Sanchez of California State University–Northridge in Northridge, Calif., show that antibiotic-resistant bacteria are present in many ready-to-eat foods such as fresh produce and dairy products and may serve as a source of human exposure to antibiotic-resistant bacteria. About 2 million people become infected with antibiotic resistant-bacteria annually in the United States, resulting in over $35 billion in additional health care costs. Examining potential ways that humans can be exposed to antibiotic-resistant bacteria can help in understanding how to counter the threat.

Decades or longer may be needed to fully assess the effects of unconventional oil and gas production on the quality of groundwater used for drinking water in Arkansas, Louisiana, and Texas

A new U.S. Geological Survey study shows that unconventional oil and gas production in some areas of Arkansas, Louisiana, and Texas is not currently a significant source of methane or benzene to drinking water wells. These production areas include the Eagle Ford, Fayetteville, and Haynesville shale formations, which are some of the largest sources of natural gas in the country and have trillions of cubic feet of gas.

Simon Fraser University researchers are investigating why some older Canadians living with multiple chronic health conditions maintain their resiliency.

Professor Andrew Wister, director of SFU’s Gerontology Research Centre, is SFU’s principal investigator for the multi-university Canadian Longitudinal Study on Aging (CLSA). He leads one of 25 research teams benefiting from a share of $1.7 million in CLSA catalyst grants, funded by the Canadian Institutes of Health Research (CIHR), announced today.

The critical component of an experimental vaccine led to an escalating immune response in patients with sarcoma, an indicator of its potential anti-cancer effects.

A computer's ability to predict a patient's lifespan simply by looking at images of their organs is a step closer to becoming a reality, thanks to new research led by the University of Adelaide.

A new U.S. Geological Survey study that looked at the extensive harmful algal bloom that plagued Florida last year found far more types of cyanobacteria present than previously known.

A new study combining European ice core data and historical records of the infamous Black Death pandemic of 1349-1353 shows metal mining and smelting have polluted the environment for thousands of years, challenging the widespread belief that environmental pollution began with the Industrial Revolution in the 1700s and 1800s.

In August 2014, toxins from algal blooms in Lake Erie shut down the city of Toledo, Ohio’s water supply, leaving half a million residents without potable water for more than two days. A new study co-authored by UT researchers shows that a virus may have been involved in the crisis and suggests methods for more stringent monitoring of water supplies.

Steven Wilhelm, Kenneth and Blaire Mossman Professor of Microbiology, along with UT graduate students Joshua Stough and Lauren Krausfeldt, worked with a team of 25 researchers to examine the physiological traits of Microcystis, the cyanobacterial organism responsible for scum-like algal blooms in Lake Erie. They found that it was consistent with algal blooms from 2012 and 2013 except for one thing—the Microcystis cells had a viral infection. Typically, toxins from algal blooms are trapped within the cell until the cell dies. But virus infections can cause cells to break open, leaking the toxin into the water and subsequently into water facility intake pipes and treatment centers.

In metropolitan areas throughout Europe maximum permissible values of nitrogen oxide are consistently breached. It has been a challenge to determine how much each polluter contributes to the emission output. Until now emission levels were mainly calculated by collecting emission data at laboratory testing facilities and subsequently extrapolating them in models. However, the amount of pollutant emissions that vehicles emit on a daily basis depends on numerous factors, for example on individual driving behavior. The recent Diesel scandal showed, for example, that measurements at engine test stands based on the New European Driving Cycle (NEDC) or similar emission testing procedures can be highly uncertain for predicting actual environmental impacts. A large number of new studies have recently been published suggesting that emission levels from test stands have to be adjusted upwards.

We all know that washing our hands can keep us from spreading germs and getting sick. But a new Rutgers-New Brunswick study found that cool water removes the same amount of harmful bacteria as hot.

“People need to feel comfortable when they are washing their hands but as far as effectiveness, this study shows us that the temperature of the water used didn’t matter,” said Donald Schaffner, distinguished professor and extension specialist in food science.
