In 60 years of space exploration, we've placed almost 7,000 satellites in orbit. Less than a third still function. The rest is dangerous junk - and their number is growing. Here's how we might mitigate the threat.
A legislative proposal in Connecticut, U.S. would mandate instruction on climate change in public schools statewide, beginning in elementary school.
New science suggests Greenland may be approaching a dangerous tipping point, with implications for global sea-level rise.
The "Future Circular Collider" is conceived as a successor to the LHC, and – if given the green light – it would allow physicists to seek answers to some of greatest mysteries in physics.
We can no longer feed our population a healthy diet while balancing planetary resources. For the first time in 200,000 years of human history, we are severely out of sync with the planet and Nature.
A Caribbean island once full of lush trees and teeming with wildlife is nearly completely deforested and undergoing a mass extinction event. More than half of the country's species predicted to be gone by 2035.
The cotton seeds sprouted inside of a container as part of the lunar mini-biosphere experiment aboard the lander. And, just over a week later, or some 213 hours, the experiment is over and the plants are dead.
A recent study has developed a system that produces electricity and hydrogen while eliminating carbon dioxide. This system has shown stability by operating for more than 1,000 hours without damage to electrodes.
According to new study, an extrasolar planet orbiting Barnard’s star, an M-type (red dwarf), that is just 6 light years away could actually support life, assuming the planet experiences enhanced geothermal activity.
For the first time, researchers have documented the long-predicted occurrence of 'walls bound by strings' in superfluid helium-3. The existence of such an object may explain how the universe cooled down.
An international team of scientists claim to have pulled off a first: Three-dimensional replicas of human blood vessels that are grown in a petri dish.
Etihad Airways has become the world's first airline to fly a commercial flight using locally produced sustainable fuel derived from plants grown in saltwater.
India introduces a ban on all single-use plastics at 129 airports across the country. This is the first step to reaching the higher goal- make all airports plastic-free.
Organic electronics are set to become more important, they provide the basis for flexible solar cells for example or future electronic paper. A new breakthrough doubles the power.
While a zero-carbon economy is undoubtedly technically feasible and easily affordable, it will not be achieved without strong public policies and forward-looking business strategies.
