Researchers modify CRISPR to reorganize genome
Researchers at Stanford University have reworked CRISPR-Cas9 gene-editing technology to manipulate the genome in three-dimensional space, allowing them to ferry genetic snippets to different locations in a cell's nucleus.
New microscope offers 4-D look at embryonic development in living mice
A smart new microscope has given scientists a front-row seat to the drama of mammalian development.
Mouse pups with same-sex parents born in China using stem cells and gene editing
Researchers at the Chinese Academy of Sciences were able to produce healthy mice with two mothers that went on to have normal offspring of their own. Mice from two dads were also born but only survived for a couple of days. ...
Ants regulate growth of seemingly 'useless' organ to make huge soldiers
Scientists at McGill have found the answer to a question that perplexed Charles Darwin. So much so, that it actually led him to doubt his own theory of evolution. He wondered, if natural selection works at the level of the ...
Uncovering the role of the ilio-sacral joint in frogs
A trio of researchers, two with the Royal Veterinary College, the other the University of Portsmouth, has found evidence that suggests that the ilio-sacral joint in frogs evolved after they started jumping. In their paper ...
Study shows land-locked Atlantic salmon also use magnetic field to navigate
A new study shows that Atlantic salmon use the Earth's magnetic field as a navigational tool—much like their cousins, Pacific salmon—and don't lose that ability through several generations of fish even after they have ...
Small-brained female guppies aren't drawn to attractive males
Female guppies with smaller brains can distinguish attractive males, but they don't recognise them as being more appealing or choose to mate with them, according to a new study by UCL and Stockholm University researchers.
Modern humans inherited viral defenses from Neanderthals
Neanderthals mysteriously disappeared about 40,000 years ago, but before vanishing they interbred with another human species that was just beginning its global spread. As a result of these ancient trysts, many modern Europeans ...
Set in amber, fossil ants help reconstruct evolution of fungus farming
Some 50 million years before humans figured it out, agriculture arrived in the world in a seemingly unlikely place: an ant hill.
