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
We crafted our first rodent car from a plastic cereal container. After trial and error, my colleagues and I found that rats could learn to drive forward by grasping a small wire that acted like a gas pedal. Before long, they were steering with surprising precision to reach a Froot Loop treat. As expected, rats … 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
Last October, an asteroid impacted Earth’s atmosphere just hours after being detected — somehow, it managed to circumvent impact monitoring systems during its approach to our planet. However, on the bright side, the object measured just 3 feet (1 meter) in diameter and posed very little threat to anything on Earth’s surface. This asteroid, designated … Read more
A structure in southwest England that’s associated with King Arthur isn’t medieval as scientists had long thought. Instead, it dates back more than 5,000 years, to the Neolithic, or New Stone Age, archaeologists say — thousands of years before the mythical king and his knights are said to have lived. The scientists who were involved … 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
Forgetting is part of our daily lives. You may walk into a room only to forget why you went in there — or perhaps someone says hi on the street and you can’t remember their name. But why do we forget things? Is it simply a sign of memory impairment, or are there benefits? One … Read more
Clouds form when water vapor — an invisible gas in the atmosphere — sticks to tiny floating particles, such as dust, and turns into liquid water droplets or ice crystals. In a newly published study, we show that microplastic particles can have the same effects, producing ice crystals at temperatures 5 to 10 degrees Celsius … 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
