One of the biggest mysteries in science—dark energy—doesn't actually exist, according to researchers looking to solve the riddle of how the universe is expanding.
Northwestern University engineers are the first to successfully demonstrate quantum teleportation over a fiberoptic cable already carrying internet traffic.
Sloths weren't always slow-moving, furry tree-dwellers. Their prehistoric ancestors were huge—up to 4 tons (3.6 metric tons)—and when startled, they brandished immense claws.
Interglacials are, as the name suggests, warm periods between planetary glaciations when the expanse of ice on Earth shrinks. Currently, we are in an 11,000 year-long interglacial period known as the Holocene. Prior to this, ...
A group of Brazilian researchers has presented an innovative proposal to resolve a decades-old debate among theoretical physicists: How many fundamental constants are needed to describe the observable universe? Here, the ...
The missing ingredient for cooking up stars in the same way you might steam your Christmas pudding has been spotted for the first time by astronomers. Much like a pressure cooker has a weight on top of its lid to keep the ...
A recent Colorado State University study published in the journal Geology demonstrates that climate change can affect the frequency of earthquakes, adding to a small but growing body of evidence showing that climate can ...
A new study explores how variations in Mars' crustal thickness during its ancient history may have influenced the planet's magmatic evolution and hydrological systems. The research, published in Earth and Planetary Science ...
After its formation, the moon may have been the scene of such immense volcanic activity that its entire crust melted several times and was completely churned through. At that time, the moon orbited significantly closer to ...
Scientists have spotted a massive black hole in the early universe that is "napping" after stuffing itself with too much food. Like a bear gorging itself on salmon before hibernating for the winter, or a much-needed nap after ...
