World’s nations start to hammer out first global treaty on plastic pollution | Science

Each year, an estimated 11 million tons of plastic waste enter the ocean, equivalent to a cargo ship’s worth every day. The rising tide—in the oceans and beyond—is just a symptom of much wider problems: unsustainable product design, short-sighted consumption, and insufficient waste management, scientists say. To curb the flood, says Jenna Jambeck, an environmental … Read more

Methane Emissions from Energy Production Are Massively Undercounted

Governments across the world are massively undercounting the amount of methane that energy production is releasing into the environment, according to a report this morning from the International Energy Agency. The agency’s annual Global Methane Tracker said emissions from the energy sector are about 70 percent greater than the amount national governments have officially reported. … Read more

Loop quantum gravity: Does space-time come in tiny chunks?

Unifying quantum mechanics with general relativity is the ultimate dream — or nightmare — of physics. It would be a way to finally describe the force of gravity with the tools of quantum mechanics, unlocking how gravity works when it’s really strong and at really small scales. Einstein’s theory of general relativity tells us that … Read more

Oldest human DNA from Africa reveals complex migrations | Science

Africa is the birthplace of our species, but ancient DNA from the continent has so far provided relatively few clues to our history there, partly because researchers have struggled to recover genetic samples that survived the hot, humid climate. Now, an analysis of ancient DNA from six individuals from southeastern Africa offers a glimpse of … Read more

Can our brains help prove the universe is conscious?

As humans, we know we are conscious because we experience and feel things. But we are still unable to explain exactly what consciousness is or where it comes from. “Consciousness — or better, conscious experience — is obviously a part of reality,” Johannes Kleiner, a mathematician and theoretical physicist at the Munich Center For Mathematical … Read more

Springtime was the season the dinosaurs died, ancient fish fossils suggest | Science

On a spring day 66 million years ago, as flowers bloomed and baby birds hatched in what is now North Dakota, a ball of fire streaked across the sky and wiped out nearly three-quarters of life on Earth. So says a new high-resolution study of fossilized fish bones, which pinpoints the season of the Cretaceous-Paleogene … Read more

Mysterious Repeating Fast Radio Burst Traced to Very Unexpected Location

A recently discovered repeating fast radio burst (FRB) named FRB 20200120E is deepening the mystery of these already deeply mysterious space signals. Astronomers have tracked its location to a galaxy 11.7 million light-years away, which makes it the closest known extragalactic fast radio burst, 40 times closer than the next-closest extragalactic signal.   But it … Read more

‘Staggering’ study reveals nearly half of unemployed U.S. men have criminal convictions | Science

One in three adults in the United States has been arrested at least once, a strikingly high number compared with many other countries. Now, a new study reveals one of the implications of that figure: Nearly half of unemployed U.S. men have a criminal conviction by age 35, which makes it harder to get a … Read more
