Bottled water hosts many thousands of nano-sized plastic bits
The finding emerges from tests of a new tool that identified smaller-than-ever tiny plastic bits in three brands of bottled water.
- Climate
Chemists make device to destroy planet-warming methane pollution
It can slash diffuse sources of this extremely potent greenhouse gas, such as from livestock barns and other sites.
- Chemistry
Pollution power? A new device turns carbon dioxide into fuel
Scientists made a device that converts the greenhouse gas into formate. This salt can then run a fuel cell to make electricity.
- Materials Science
A new hydrogel could help pull drinking water from the air
The salty gel absorbs more water from the air than similar gels, even in desert climates. This could provide clean water for drinking or farming.
- Tech
New device can harvest clean energy from humid air anywhere
Unlike solar power, this new source of electricity is available day or night.
- Tech
High-tech solar ‘leaves’ create green fuels from the sun
Chemists make a liquid alternative to fossil fuels from carbon dioxide, water and the sun. Their trick? They use a new type of artificial leaf.
- Climate
For greener toilets and air conditioning, consider saltwater
Using saltwater would allow coastal cities to save their freshwater for drinking and to reduce their carbon footprints. Some could save money, too.
- Psychology
Supportive spaces help LGBTQ+ youth thrive in school and beyond
Schools are safer and more welcoming when their policies respect and affirm LGBTQ+ students. Clubs can push for changes that boost kids’ mental health.
- Climate
Eight ways you can cut your carbon footprint
Learn how you can limit the climate-warming gases associated with what you eat, the products you buy and the energy you use.
- Environment
Gas stoves can spew lots of pollution, even when they’re turned off
A new study finds they can leak benzene and other harmful chemicals into homes, sometimes at very high levels.
- Environment
For a better brick, just add poop
Sewage sludge. Cow dung. They’re not just waste — scientists are finding uses for processed poop in construction materials.
- Climate
Green energy is cheaper than fossil fuels, a new study finds
Switching over to clean, renewable power — and away from fossil fuels — could save trillions of dollars by 2050, a new study finds.
