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.

Worldwide, three new cars roll off the line every second – that’s 73 cars and 18 million utility vehicles per year. Most run on gasoline. In industrialized nations, the trend is moving towards so-called downsizing engines: smaller but with direct gasoline injection and turbocharging. This technology is kind to the environment and saves fuel, the manufacturers say. Experts estimate that by 2020, 50 million of these direct-injection gasoline engines will be running on the roads all over Europe – high time the cocktail of exhaust emissions from these engines were examined closely.

It started with vomiting and a fever. But a few days later, five-month old Liam was in the emergency room, his tiny body gripped by hourly waves of seizures. X-rays and MRIs showed deep swelling in his brain. When an infectious disease specialist at Connecticut Children’s Medical Center diagnosed Liam with Powassan virus in November, he became the first recorded case in state history. Doctors think Liam picked up the rare neurological disease from a tick his father brought back after a deer hunting trip.

New research from the University of Cincinnati (UC) reveals that residents of the Mid-Ohio River Valley (from Evansville, Indiana, north to Huntington, West Virginia) had higher than normal levels of perfluorooctanoic acid (PFOA) based on blood samples collected over a 22-year span. The exposure source was likely from drinking water contaminated by industrial discharges upriver. 

The study, appearing in the latest publication of Environmental Pollution, looked at levels of PFOA and 10 other per- and polyfluoroalkyl substances (PFAS) in 931 Mid-Ohio River Valley residents, testing blood serum samples collected between 1991 and 2013, to determine whether the Ohio River and Ohio River Aquifer were sources of exposure. This is the first study of PFOA serum concentrations in U.S. residents in the 1990s.
