Your stress may be contagious to your dog. (Credit: Klymenok Olena/Shutterstock)
A knowing glance. A paw on your arm. A lick on the cheek. Most dog owners can recall a time when they were feeling down. And somehow, their dog just knew something was wrong and responded with a loving gesture.
Many dog lovers have long believed that canines are able to sense human emotions. And, a growing body of evidence on the emotional connection between man and his best friend adds weight to these heart ...read more

When researchers edit genes with CRISPR today, their systems chop a strand of DNA in half before inserting a new gene and allowing a cell's natural healing mechanisms to patch the strand back up.
That technique works well overall, but it can lead to errors, and the success rate varies depending on the type of cell. Scientists have been on the hunt for better versions of CRISPR for years.
Now, a new protein that can insert custom genes into DNA witho ...read more

In 1503, a storm sank the Portuguese ship Esmeralda off the southeastern coast of the Arabian Peninsula, taking the lives of the crew. In 2014, divers and archaeologists returned to the wreck to retrieve what remained. That included this metal disk, thought to be an astrolabe — an instrument that mariners used to navigate by measuring the height of celestial bodies above the horizon.
Two features of the Portuguese flag — the coat of arms and an armillary ...read more

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
