In the 2016 science fiction movie Arrival, a linguist is faced with the daunting task of deciphering an alien language consisting of palindromic phrases, which read the same backwards as they do forwards, written with circular symbols. As she discovers various clues, different nations around the world interpret the messages differently — with some assuming … Read more
The rise of artificial intelligence (AI) poses questions not just for technology and the expanded plethora of possibilities it brings, but for morality, ethics and philosophy too. Ushering in this new technology carries implications for health, law, the military, the nature of work, politics and even our own identities — what makes us human and … Read more
Tardigrades, the ubiquitous microscopic animals that resemble gummy bears with eight legs, are renowned for their ability to survive some of the harshest environmental conditions for decades without food and water. These hardy animals can easily endure levels of radiation that would be lethal to most other forms of life, extreme temperatures and even survive … Read more
Scientists may have discovered an unlikely ally in the fight against plastic waste: the lesser mealworm. Native to Africa but now widespread across the planet, a beetle larvae from the Alphitobius genus can consume and degrade plastic, the researchers found. The finding could be particularly useful in combating plastic pollution in Africa, the researchers noted. … Read more
Earth’s surface is a turbulent place. Mountains rise, continents merge and split, and earthquakes shake the ground. All of these processes result from plate tectonics, the movement of enormous chunks of Earth’s crust. This movement may be why life exists here. Earth is the only known planet with plate tectonics and the only known planet … Read more
Scientists have discovered that the icy shell of Saturn’s largest moon, Titan, could possess an insulated, six-mile-thick (9.7-kilometer-thick) layer of methane ice beneath its surface. Ironically, this layer may make signs of life from the subsurface ocean of Titan easier to detect. And, down the line, the discovery could benefit the fight against human-driven climate … Read more
Global warming caused vital Atlantic Ocean currents to collapse just before the last ice age, a new study suggests. The weakening currents triggered a cascade of effects, resulting in a dramatic cooling of the Nordic Seas — the Greenland, Iceland and Norwegian seas — while the surrounding oceans grew warmer. And scientists say we could … Read more
Even though the invention of the wheel around 6,000 years ago revolutionized everything from transportation to pottery making, its exact origins are still a mystery to archaeologists. But a new study using techniques from structural mechanics suggests that Eastern European copper miners may have been the driving force behind three major innovations in wheel technology … Read more
Forty-four of the world’s leading climate scientists have called on Nordic policymakers to address the potentially imminent and “devastating” collapse of key Atlantic Ocean currents. In an open letter published online Monday (Oct. 21), University of Pennsylvania climatologist Michael Mann and other eminent scientists say the risks of weakening ocean circulation in the Atlantic have … Read more
Tiny photosynthetic microbes could be secretly thriving on Mars — hiding inside small bubbles of liquid water in the thin layers of dusty ice that litter the Red Planet’s surface, a new NASA-led study reveals. Researchers believe the icy patches could be among the most promising targets in the hunt for extraterrestrial life within our … Read more
