The piercing blue eyes of huskies — those beloved, wolf-like canines — stand out among most dog breeds. Now, using genetic tests, scientists find where blue-eyed Siberian huskies get their distinctive eye color. The researchers say this marks another step in our understanding of canine genetics.
“This is the first discovery that’s been made this way outside of humans,” said Adam Boyko, a genomics researcher at Cornell University in Ithaca, New York and co-founder o ...read more
It’s a big week for CRISPR! Despite being a world apart, two separate research groups had the same idea: to see if CRISPR gene editing can really mimic conventional plant breeding.
One group re-domesticated a wild tomato plant; the other used a similar approach to domesticate an entirely new crop: the ground cherry, a tomato relative.
Together, the new work demonstrates how dramatically gene editing technology could speed up crop improvement efforts worldwide.
How to Make a Crop Worth ...read more
Researchers have taught a population of wild sparrows to sing a different song.
Out today in Current Biology, the research suggests new answers to the question of how birds learn to sing.
“This was a risky experiment we conducted because we didn’t know if it was going to work,” says Dan Mennill, lead author of the study.
Mennill explains that song learning has been studied for years in controlled laboratory settings. But it’s much more difficult to run an experime ...read more
It's not easy being a bee these days. Apis mellifera, the Western honey bee, is crucial to agriculture worldwide but faces a growing number of pests and pathogens against which beekeepers have few weapons.
But the bees themselves may be showing us the way forward: New research suggests the foraging insects may obtain protection against some viruses by consuming fungi, then returning to the hive to spread its medicinal value.
Honey bees contribute more than $15 billion annually to U.S ...read more
At vast cosmic distances, supermassive black holes called quasars gobble up matter into accretion disks that shine so brightly, they overpower the light from entire galaxies. Closer to home, compact objects called microquasars give astronomers a scaled-down taste of the processes at work inside the faraway behemoths. Now, an international collaboration of researchers has announced in the journal Nature that they’ve detected the first gamma-ray signal from the ends of the two jets spewing o ...read more
The Milky Way is apparently a hotspot for stars immigrating from other galaxies.
In a new study published in Monthly Notices of the Royal Astronomical Society, a trio of astronomers set out to find hypervelocity stars fleeing our galaxy, but surprisingly discovered most of the rapidly moving stars are actually barreling into the Milky Way from galaxies beyond.
"Rather than flying away from the [Milky Way's] Galactic Center, most of the high velocity stars we spotted seem to be racing ...read more
Arguments with loved ones or a stressful conversation with the boss can bring you down. Now, new research provides scientific evidence that getting a hug on the same day you’ve had a conflict can lift your spirits. The finding suggests hugs are a simple yet effective way to relieve relationship stress, romantic or not.
People commonly communicate affection by hugging, holding hands, or even a pat on the back. And past research shows physical contact has psychological and physical hea ...read more
The MASCOT has landed.
As of two weeks ago, humans had never put a single robotic explorer on an asteroid. Now we have three of them hopping about on Ryugu, a 900-meter-wide object currently orbiting on the other side of the Sun. On September 20, Japan's Hayabusa2 probe dropped two little landers, MINERVA II-1a and II-1b. They promptly sent back dizzying images from the surface. Then last night (October 3), the mothership deployed MASCOT, a much larger rover that is now performing a batte ...read more
Astronomers say they may have found the first confirmed exomoon, or moon orbiting a planet outside of our solar system. However, the pair of astronomers behind the find say it's much too soon to completely prove the exomoon’s presence.
After looking through recent data from NASA’s Kepler space telescope, Alex Teachey, a graduate researcher in the department of astronomy at Columbia University, and David M. Kipping, an assistant professor in the same department, spotted evidence that ...read more
As humans, sexually-transmitted microbes worry us. They can cause some pretty nasty diseases, and we've learned to take precautions. But, some creatures actually welcome the tiny hitchhikers that can jump ship during mating. For dung beetles, the act of procreation can sometimes come with an extra benefit: Nematode worms.
Just as there are countless species of bacteria living on and in us that help our bodies out, not every sexually-transmitted creature is out to cause harm. For the dung ...read more
