Researchers using ice-penetrating radar have discovered mountain ranges and valleys far beneath the ice in Antarctica. The deep valleys are hundreds of miles long, and can influence the flow of glaciers to the sea. Scientists are learning how the hidden mountains cause the East and West Antarctic ice sheets to interact with each other.

Scientists have figured out how to heat water faster. By using a laser pulse made of x-rays, they heated water to 100,000 degrees Celsius, in 75 femtoseconds (which is a millionth of a billionth second). Heating water molecules usually makes them shake stronger and stronger. An x-ray laser punches the electrons right off the molecule!

Hiccups are annoying. It happens when your diaphragm has an involuntary spasm and makes your vocal chords snap shut. Your diaphragm is the muscle separating the spaces holding your heart and stomach. There are many tricks that are supposed to get rid of hiccups, but scientists say there’s no real cure. Try them all!

Scientists have invented laser eyeballs! Well, not exactly… They actually created a thin film that emits laser light, and attached it to a contact lens. The lasers could also be attached to things like money or fingernails. Now they just have to figure out a good use for them, other than bragging about having laser eyes!

Scientists are working on a vaccine that could one day turn off peanut allergies! The vaccine has been successful with mice, after only 3 doses. The next step will be to perform clinical trials with people, to see if they get the same results. Peanut allergies are common and dangerous, so this could be an amazing solution!

Kuh-boom! You’ve probably heard thunder from a rainstorm before. Maybe you’ve even heard thunder during a snowstorm. But scientists have captured the sound of thunder in ash clouds from an erupting volcano! They hope studying the thunder can help them detect lightning in large plumes of ash that interfere with airplanes.

If your parents haven’t let you have a phone yet, maybe you should say thank you! Scientists say that phone notifications trigger a stress response in our bodies similar to being in danger. Phone alerts interrupt whatever you’re doing, making you spend energy to refocus. Try turning off alerts and keeping devices in your backpack.

You scratch my back and I’ll scratch yours! The phrase means doing something for someone and expecting a favor in return. Scientists showed animals can behave the same way. Norway rats are more likely to share food with rats who groomed their necks, and vice versa. It pays to be nice to each other!

Japanese scientists have discovered a new species of worm that lives on the seafloor of the Pacific Ocean. The Xenoturbella japonica is an orange sack-like creature with no internal organs. The two inch-long worm also has no butt! It eats and expels waste from the same opening. He’s a real potty-mouth!

The Great Barrier Reef is an ecosystem of coral reefs over 1400 miles long off the coast of Australia. It’s the largest living thing on Earth. But pollution, climate change and coral bleaching are killing the reef. Scientists have been able to transplant healthy coral to help nurse the reef back to health.
