A raft of “space bubbles” could be used to reverse global warming, according to an MIT group's solar geoengineering proposal.
A “Peter Pan” chemical could stop mosquitoes, without hurting other insects
Entomologist Naoki Yamanaka has an idea for how to handle mosquitoes: What if we just stop them from growing up?
Solar + battery hybrids are poised for explosive growth
Solar panels and battery storage can generate renewable power when solar energy is at its peak during the day and then release it as needed.
3 emerging technologies that will give renewable energy storage a boost
The U.S. Department of Energy has predicted that renewable energy will be the fastest-growing U.S. energy source through 2050.
See the world’s first floating city: OCEANIX Busan
If the world's first floating city is a success, other coastal metropolises could use it as a blueprint for adapting to rising sea levels.
This German firm is building a floating solar plant on a quarry lake
A German company will switch on a floating solar power plant, a rapidly-installed, renewable technology that could help phase out oil.
WWF report highlights tiger population gains for the Year of the Tiger
The global tiger population is finally increasing after more than a century of gradual decline, a new study from WWF reveals.
Big tech companies pledge nearly $1 billion toward carbon removal
The pledge is an advance market commitment — an economic strategy that's been used to increase vaccine coverage across the planet.
Unbelievably sensitive NACHOS satellite is ready to save lives
The cutting-edge NACHOS satellite will aid in our fight against climate change and potentially save hundreds of people from gruesome deaths.
Smart sensor tells you exactly when fruit will ripen — or spoil
Inside vast warehouses, millions of fruits sit and slowly ripen. To help packers know when fruit has got to go, a biotech startup is turning to small sensors.
Lasers from space create unique new map of Earth’s forests
A lidar instrument on the ISS has been used to create a near-global 3D map of the Earth’s biomass for conservation and climate research.
Methane-eating bacteria discovery could help capture gas from the air
A new discovery could kickstart efforts to engineer methane-harvesting bacteria, fight greenhouse emissions, and “mine” the air.
The West Coast wants to tap into the maple sugar market
Over 75% of the world’s maple syrup production is in Quebec. But with climate change threatening their seasons, West Coast producers are looking to tap in.
World’s first fully-recyclable wind turbine blade prototype debuts
Wind turbine blades are notoriously difficult to recycle, but researchers and industry players hope a new material design may change that.
Engineered bacteria convert CO2 into valuable industrial chemicals
Many industrial chemicals have a large carbon footprint. But scientists have engineered bacteria that ferments carbon dioxide from the air to make industrial chemicals
This company is tackling Kuwait’s ‘tire graveyard’ problem by tire recycling
Kuwait wants to build 25,000 new houses on the site of a former tire graveyard. Here's how they're going to do it.
First solar canal project is a win for water, energy, air and climate in California
California’s aging power infrastructure has contributed to catastrophic wildfires and multiday outages. Solar canals can help.
Could electrocuting clouds be the key to making it rain?
By analyzing the energy within raindrops, researchers found that they could squeeze water from the clouds by electrically supercharging them - another step to control the weather.
