An active groundwater system may still be thriving on Mars hundreds of meters beneath the surface, according to new research. Though recent studies have detected the presence of deep lakes near Mars’ south pole, features linked to water in areas closer to the equator have largely been attributed to flows at or near the surface.

You may soon be able to reach into the fridge without feeling guilty that you are contributing to greenhouse gases, if a new way to power fridges is adopted. A solid substance known as plastic crystals offers a greener alternatives to the gases currently used in fridges and air conditioning, experts say. Fridges cool by

Iconic animals such as wildebeest, zebra, and gazelles are being threatened by a rapidly growing human population around world famous national parks. The borders of the Masai Mara and Serengeti national parks are seeing human numbers soar while the amount of animals is plummeting. As a result of human interference in these vast natural areas,

Ninety amphibian species have been wiped out thanks to a deadly fungal disease. It affects frogs, toads and salamanders and has caused a dramatic population collapse in more than 400 species in the past 50 years. The disease is called chytridiomycosis which eats away at the skin of amphibians and is threatening to send more animals

We’ve learned a lot about Neptune’s largest moon, Triton, since it was first discovered in 1846. Some scientists believe it could be an “ocean world” with liquid water – and maybe even harbor life. And now, pending approval, we might soon get our best glimpse yet. NASA’s Jet Propulsion Laboratory proposed on Tuesday at a conference in Texas

We may not yet have found evidence of alien life, but that doesn’t mean it hasn’t found us. This is according to a group of scientists who gathered this week in Paris to discuss why, despite decades of searching and the high probability that life exists beyond our own atmosphere, we’ve yet to make contact.

NASA on Friday published satellite photos of a powerful meteor which appeared just above the Bering Sea on December 18 but went unnoticed until months later. The explosion unleashed around 173 kilotons of energy, more than 10 times that of the atomic bomb blast over Hiroshima in World War II. Images captured minutes after the fireball

Human remains thought to be about 4,000 years old and ‘charred’ have been discovered by builders working on a hotel in rural Northumberland. The Tankerville Arms in Wooler was undergoing renovation work when they unearthed a Bronze Age stone burial chamber – or cist. A digger driver was laying drainage pipes when he struck the stone

Bears can exactly mimic another bear’s facial expressions, casting doubt on humans and other primates being the only mammals able to express their emotions. Sun bears have been observed opening their mouths to match their playmates when they are interacting face-to-face. Researchers claim that such facial mimicry has not been seen in primates outside humans

Holiday makers may soon be flying abroad on jets powered by scraps of wood, according to new research. A green fuel that converts plant waste from farm and timber harvests into aviation fuel has been developed by scientists. They say it could help combat climate change by reducing CO² emissions from aircraft and rockets. The gas is
