These rats are in special cages for urine collection. Every year, millions of animals are used for testing chemicals that are used in industrial products.
Testing new industrial chemicals is essential for public health and the environment. But animal testing is costly, and too many chemicals are left untested. A new AI tool may solve the problem.
Chemical companies touted synthetic insecticides and herbicides as miracle products in the 1940s and 1950s. But farmers and cropdusting pilots didn't always buy the sales pitch.

According to one study, more than 8 million people per year die early from air pollution exposure.
The Victorian mountain ash forest has been severely affected by fires and logging. To determine the actual health of the forest, we need to look at the quality, not just the quantity of what remains.
In the aftermath of fires or logging, conservation needs to focus on recovering the health of the remaining vegetation, not just the size of the forest or woodland.
There are nanometals in your washing machine.
Many socks, towels and other textiles are treated with silver nanoparticles to kill germs and odors. When the silver washes out, it can pollute waterways. Two chemists propose a way to collect it from wastewater.

Climate change threatens to widen the health gap between the haves and have-nots. Here's why addressing environmental issues that drive poor health is a starting point.
Marine waters are an important source of food for Inuit.
The North Water Polynya, or Pikialasorsuaq, is a key ocean area for Arctic animals and for Inuit hunting and fishing. Rocket launches threaten to contaminate the area with harmful chemicals.
A U.S. agency has warned the public about the dangers of flame retardants known as organohalogens that are found in baby toys, mattresses, furniture and electronics.
The U.S. Consumer Protection Safety Commission has recommended a wide-spread ban on an entire class of flame retardants. Here's how Canada could follow suit.

New research shows that noise pollution in US cities is concentrated in poor and minority communities. Beyond regulating airplane noise, the US has done relatively little to curb noise pollution.
Social media posts, such as this image uploaded to Flickr, can be repurposed for reef health monitoring.

Mining social media posts from tourism hotspots such as coral reefs could turn tourists into environmental citizen scientists without them even realising it.
Drug resistance to cholera causing bacteria affects treatment especially in developing countries.
Cholera is caused by a lack of access to clean drinking water and unhygienic conditions. Misuse of antibiotics makes it difficult and expensive to treat outbreaks.
The health benefits of being close to nature are well established.

Health benefits of being close to nature are well established, but the rise of apartment living means we can't always be close to greenery.
Dancing sunlight patterns reflected onto an interior ceiling from a wind-disturbed external water surface.
Research shows that bringing nature indoors, in the form of movement created by light, wind and water, makes occupants calmer and more productive. It also could promote interest in sustainable design.
Wind turbines require massive structures that are polluting to produce and can harm ecosystems, but these impacts compare favorably with those of fossil alternatives.
No energy source is perfect, but solar and wind have a much lower health and environmental footprint than fossil fuels, a study finds. Biopower, though, is a mixed bag.
An innovative water-sensitive project aims to dramatically improve the health of slums and their environment together.
A five-year project announced today will implement an innovative water-sensitive approach tailored to informal settlements. The goal is to revitalise 24 communities in Fiji and Indonesia.
We all want to keep our food in tip top condition but very few of us know how to use fridges properly.
We propose a different way to look at the factors behind chronic disease, like obesity and diabetes.
A new way of looking at what's behind chronic disease takes into account social, environmental and other factors, rather than blaming individuals.
Dr. Kofi Amegah of the University of Cape Coast, Ghana, installing a small air sensing unit built by the University of Massachusetts.
Citizens and activists are using cheap off-the-shelf sensors to collect their own data on air pollution. It's a promising trend, but these devices have serious technical limitations.
Loy Yang power station in the Latrobe Valley, Victoria, is one station doctors think should be a priority for closure.
Coal-fired power stations need to be closed within the next decade on health grounds. Here's why.
