Plastic pollution is changing entire Earth system, scientists find

[…] In 2022 at least 506m tonnes of plastics were produced worldwide, but only 9% gets recycled globally. The rest is burned, landfilled or dumped where it can leach into the environment. Microplastics are now everywhere, from the top of Mount Everest to the Mariana Trench, the deepest point on earth.

A simple experiment revealed the complex ‘thoughts’ of fungi – yes vegans and vegetarians: plants also really live and think.

Fungi are fascinating lifeforms that defy conventional notions of animal intelligence. They don’t have brains, yet display clear signs of decision making and communication. But just how complex are these organisms and what can they tell us about other forms of awareness? To begin investigating these mysteries, researchers at Japan’s Tohoku University and Nagaoka College Read more about A simple experiment revealed the complex ‘thoughts’ of fungi – yes vegans and vegetarians: plants also really live and think.[…]

It could take over 40 years for PFAS to leave groundwater

Per- and polyfluoroalkyl chemicals, known commonly as PFAS, could take over 40 years to flush out of contaminated groundwater in North Carolina’s Cumberland and Bladen counties, according to a new study from North Carolina State University. The study used a novel combination of data on PFAS, groundwater age-dating tracers, and groundwater flux to forecast PFAS Read more about It could take over 40 years for PFAS to leave groundwater[…]

How personal care products affect indoor air quality

The personal care products we use on a daily basis significantly affect indoor air quality, according to new research by a team at EPFL. When used indoors, these products release a cocktail of more than 200 volatile organic compounds (VOCs) into the air, and when those VOCs come into contact with ozone, the chemical reactions Read more about How personal care products affect indoor air quality[…]

String Theorists Accidentally Find a New Formula for Pi

[…] most recently in January 2024, when physicists Arnab Priya Saha and Aninda Sinha of the Indian Institute of Science presented a completely new formula for calculating it, which they later published in Physical Review Letters. Saha and Sinha are not mathematicians. They were not even looking for a novel pi equation. Rather, these two Read more about String Theorists Accidentally Find a New Formula for Pi[…]

Researchers figure out how to keep clocks on the Earth, Moon in sync

[…] Our communications and GPS networks all depend on keeping careful track of the precise timing of signals—including accounting for the effects of relativity. The deeper into a gravitational well you go, the slower time moves, and we’ve reached the point where we can detect differences in altitude of a single millimeter. Time literally flows Read more about Researchers figure out how to keep clocks on the Earth, Moon in sync[…]

Dual action antibiotic could make bacterial resistance nearly impossible

A new antibiotic that works by disrupting two different cellular targets would make it 100 million times more difficult for bacteria to evolve resistance, according to new research from the University of Illinois Chicago.
