Heart rate is one of the most basic and important indicators of health, providing a snapshot into a person’s physical activity, stress and anxiety, hydration level, and more.
Study Finds We’ll Lose Almost 40 Percent of Our Glacial Ice
A recent study published in Science used glacier models to better understand the effect that each degree of global warming will have on worldwide glacier melt.
Scientists create biodegradable plastic stronger than PET
A Japanese research team successfully harnessed E. coli to produce PDCA, a strong, biodegradable plastic alternative. Their method avoids toxic byproducts and achieves record production levels, overcoming key roadblocks with creative fixes.
Fossil reveals a 310-million-year-old fish that ate with a hidden second jaw
Scientists uncovered a 310-million-year-old fish fossil with a “tongue bite,” teeth on the roof and floor of its mouth that worked like a second jaw. This adaptation, previously thought to have appeared much later, shows how fish rapidly experimented with new feeding strategies after mass extinction.
A tiny embryo fold changed the course of evolution
A small tissue fold in fly embryos, once thought purposeless, plays a vital role in stabilizing tissues. Researchers show that it absorbs stress during early development, and its position and timing likely shaped its evolutionary emergence.
New Self-Assembling Material Could be the Key to Recyclable EV Batteries
Today’s electric vehicle boom is tomorrow’s mountain of electronic waste. And while myriad efforts are underway to improve battery recycling, many EV batteries still end up in landfills.
Deforestation May Cause Over a Third of Heat-Related Deaths in Tropical Regions
Deforestation in tropical countries could contribute to increased deaths from heat exposure in nearby populations, new research has shown.
Student Project Reveals the Underwater World of Falmouth Harbour
A student from the University of Plymouth is using her dissertation project to reveal some of the fascinating marine life living in the waters of Falmouth Harbour.
The flawed carbon math that lets major polluters off the hook
Past climate assessments let big polluters delay action, placing more burden on smaller nations. A new method based on historical responsibility demands steep cuts from wealthy countries and more financial support for poorer ones. Courts are now stepping in, making climate justice not just political but also legal.
A simple metal could solve the world’s plastic recycling problem
Scientists at Northwestern University have developed a groundbreaking nickel-based catalyst that could transform the way the world recycles plastic. Instead of requiring tedious sorting, the catalyst selectively breaks down stubborn polyolefin plastics—the single-use materials that make up much of our daily waste—into valuable oils, waxes, fuels, and more.
