New advice on medication disposal: Trash beats take-back, new study suggests
Returning extra medicine to the pharmacy for disposal might not be worth the extra time, money or greenhouse gas emissions, according to a study that is the first to look at the net effects of so-called take-back programs.

Mixed bacterial communities evolve to share resources, not compete
New research shows how bacteria evolve to increase ecosystem functioning by recycling each other's waste. The study provides some of the first evidence for how interactions between species shape evolution when there is a diverse community.

A practical guide to green products and services
A new report provides key information for policy makers and business managers on how to assess the environmental impacts of products and services. It helps to pave the way towards a resource-efficient Europe and aims to help design more sustainable products, which are indispensable in a world of 7 billion people and limited resources.

Plastic trash altering ocean habitats
A 100-fold upsurge in human-produced plastic garbage in the ocean is altering habitats in the marine environment, according to a new study.

Effect of groundwater use: Using water from wells leads to sea level rise, cancels out effect of dams
As people pump groundwater for irrigation, drinking water, and industrial uses, the water doesn't just seep back into the ground -- it also evaporates into the atmosphere, or runs off into rivers and canals, eventually emptying into the world's oceans. This water adds up, and a new study calculates that by 2050, groundwater pumping will cause a global sea level rise of about 0.8 millimeters per year.

Student-devised process would prep Chinese shale gas for sale
Chemical engineering students have designed an environmentally friendly process for turning shale gas extracted from China's Sichuan Basin into a range of profitable products.

From decade to decade: What's the status of our groundwater quality?
There was no change in concentrations of chloride, dissolved solids, or nitrate in groundwater for more than 50 percent of well networks sampled in a new analysis by the USGS that compared samples from 1988-2000 to samples from 2001-2010. For those networks that did have a change, seven times more networks saw increases as opposed to decreases.

First evaluation of the Clean Water Act's effects on coastal waters in California reveals major successes
Levels of copper, cadmium, lead and other metals in Southern California's coastal waters have plummeted over the past four decades, which researchers attribute to sewage treatment regulations that were part of the Clean Water Act of 1972 and to the phase-out of leaded gasoline in the 1970s and 1980s.

Wind pushes plastics deeper into oceans, driving trash estimates up
Decades of research into how much plastic litters the ocean, conducted by skimming only the surface, may in some cases vastly underestimate the true amount of plastic debris, according to an oceanographer.

New harvesting approach boosts energy output from bacteria
A novel energy system increases the amount of energy harvested from microbial fuel cells by more than 70 times.

Most detailed maps yet of Africa's groundwater shows scattergun approach to borehole drilling likely to be unsuccessful
A scattergun approach to borehole drilling in Africa is likely to be unsuccessful. This is the message from a group of researchers who have, for the first time, quantified the amount, and potential yield, of groundwater across the whole of Africa. They estimate the total volume of groundwater to be around 0.66 million km3 ? more than 100 times the available surface freshwater on the continent ? and hope that the assessment can inform plans to improve access to water in Africa, where 300 million people do not have access to safe drinking water.

New technology uses less water and produces energy and fertilizer at the same time
Water is a valuable resource. New technologies are making it easier to handle drinking water responsibly, purify wastewater effectively and even recover biogas and fertilizer.

Unique adaptations to a symbiotic lifestyle reveal novel targets for aphid insecticides
Biologists have potential new targets for aphid-specific insecticides. Aphids' diet of plants' sugary sap is limited in nitrogenous essential amino acids. To solve this problem, the aphid must use a bacterial symbiont, Buchnera, that lives inside special insect cells and supplements the animal's diet with the required nutrients.

A toxic menu: Marine worm feeds on carbon monoxide and hydrogen sulphide with the help of symbiotic bacteria
Scientists have revealed that a small marine worm, faced with a scarce food supply in the sandy sediments it lives in off the coast of Elba, must deal with a highly poisonous menu: this worm lives on carbon monoxide and hydrogen sulphide.

Plastic garbage in oceans: Understanding marine pollution from microplastic particles
Biologists have prepared guidelines for a more precise investigation into marine pollution from microplastic particles.

New insights into when beach sand may become unsafe for digging and other contact
With summer days at the beach on the minds of millions of winter-weary people, a new study provides health departments with information needed to determine when levels of disease-causing bacteria in beach sand could pose a risk to children and others who dig or play in the sand.

Fasting for Lent forces hyenas to change diet
Many Christians give up certain foods for Lent, however ecologists have discovered these changes in human diet have a dramatic impact on the diet of wild animals. In Ethiopia, members of the Orthodox Tewahedo Church stop eating meat and dairy products during a 55-day fast before Easter. As a result, spotted hyenas too change their eating habits.

New options for nuclear waste? Crushing pressure surprisingly opens up nanopores in mineral
By squeezing a porous solid, scientists surprisingly made its cavities open wider, letting in -- and trapping -- europium ions. Given the similarities between europium and uranium ions, the team thinks the innovation could represent a promising new avenue for nuclear waste processing.

Two-in-one device uses sewage as fuel to make electricity and clean the sewage
Scientists have described a new and more efficient version of an innovative device the size of a washing machine that uses bacteria growing in municipal sewage to make electricity and clean up the sewage at the same time. Commercial versions of the two-in-one device could be a boon for the developing world and water-short parts of the U.S.

Antibiotic resistance genes accumulating in Lake Geneva
Large quantities of antibiotic-resistant bacteria enter the environment via municipal ? and especially hospital ? wastewater streams. Although wastewater treatment plants reduce the total number of bacteria, the most hazardous ? multiresistant ? strains appear to withstand or even to be promoted by treatment processes.
