Plastics are everywhere, from our phones to our cars to our utensils. Now researchers find they're inside our bodies as well. Americans consume more than 70,000 microplastic particles every year, a new study says. That sounds like a lot, but that number is still likely an underestimate, the researchers say. The consequences to human health are largely unknown.
“The results of our study support the concept that we are living in a ‘plastic environme ...read more
Engineers hope the real InSight on Mars can use its robotic arm to help the mole start digging again, a test that has succeeded with replica instruments on Earth. (Credit: NASA/JPL-Caltech)
The digging instrument on NASA’s Mars InSight lander has been stuck since February 28, and engineers have been hard at work trying to get it moving again. The problem is with its Heat Flow and Physical Properties Package, or HP3, and specifically the part known as the mole, which auto-hammers its way ...read more

In the cutthroat Hollywood film industry, is it possible to know if an actor’s career is about to boom or bust? In many cases, yes.
Researchers from Queen Mary University in London created an algorithm that can predict with 85 percent accuracy whether a star’s golden years have passed or are still yet to come. In a study published June 4 in the open-access journal Nature Communications, scientists analyzed the profil ...read more

Who
were the First Americans? It's a question that for decades has divided researchers,
who have proposed competing theories as to how humans moved from Eurasia into
North America.
The
question is far from settled, though it is clear that by about 14,500 years ago
(and perhaps as far back as 30,000 years ago) humans had mov ...read more

A binary asteroid named 1999 KW4 passed some 32 million miles (5.2
million km) from Earth on May 25, giving astronomers a good look at a space
rock that won’t come this close again for nearly two decades. The flyby brought
it about 14 times farther away than our Moon, but still close enough for
astronomers t ...read more
