Sprinkling diamond dust into the atmosphere could offset almost all the warming caused by humans since the industrial revolution and “buy us some time” with climate change, scientists say. New research indicates that shooting 5.5 million tons (5 million metric tons) of diamond dust into the stratosphere every year could cool the planet by 1.8 … Read more
Virtual reality (VR) experiences could soon get a lot more realistic thanks to a lickable device that lets you “taste” in virtual environments. The small, lollipop-like interface simulates up to nine flavors and can even be combined with smells to make the sensation of taste feel lifelike, scientists said in a new study published Nov. … Read more
NASA scientists have revealed the secrets of the most volcanic body in our solar system, according to new research. The discovery solves a 44-year-old mystery of why, and how, Jupiter’s violent moon, Io, became so volcanically active. Io is only slightly larger than our moon, with a diameter of 2,237 miles (3,600 kilometers), and has … Read more
If you’ve ever seen yourself through a thermal imaging camera, you’ll know that your body produces lots of heat. This is in fact a waste product of our metabolism. Every square foot of the human body gives off heat equivalent to about 19 matches per hour. Unfortunately, much of this heat simply escapes into the … Read more
Earth’s total fresh water has plummeted to an alarming new low, and it could be a sign that climate change is pushing the world into a dangerous phase of global drying, according to a new study. Since 2015, our planet’s lakes, rivers and aquifers have lost 290 cubic miles (1,200 cubic km) of fresh water, … Read more
In an early-stage clinical trial, scientists used designer immune cells to “reboot” the immune systems of patients with various autoimmune diseases. The trial used a form of chimeric antigen receptor (CAR) T cell therapy, which has become a mainstay treatment for blood cancers, like leukemia. Only a few patients were included in this initial trial, … Read more
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
