In the experiment, researchers taught male mice to fear the smell of cherry blossoms by associating the scent with mild foot shocks. Two weeks later, they bred with females. The resulting pups were raised to adulthood having never been [...]

DNA analysis presented at the Royal Society in London shows, Nature says in the most delicate way possible, that ancient humans were getting it on more than we suspected:
The ancient genomes, one from a Neanderthal and one from a member of an archaic human group called the Denisovans, were presented on 18 November at a meeting on ancient DNA [...]
BBC reports on the struggle to develop an early blood test for Alzheimer’s:
A technique published in the journal Genome Biology showed differences in the tiny fragments of genetic material floating in the blood could be used to identify patients.
The test was accurate 93% of the time in trials on 202 people.
…[Alzheimer's] starts years before symptoms appear and it is [...]
Slate has printed his controversial plan to live up to the promise of gene science without the industrial agriculture downside:
The GMO story has become mired in the eco-wrecking narrative of industrial agriculture, and that is too bad for those who understand the real risks of climate change and discern our desperate need for innovation. And while the blue-sky [...]
Nature, in what was almost certainly not an April Fools’ gag, reports that there’s genetic evidence, now, that Polynesians traveled to the Amazon in days gone by – because old Brazilians share DNA with South Pacific islanders:
Indigenous people that lived in southeastern Brazil in the late 1800s shared some genetic sequences with Polynesians, an analysis of their remains [...]
BBC reveals that giant squid, no matter where they’re found or how different from each other they look, are all genetically really close to one another:
An international team of researchers investigated rare samples of the elusive animals’ DNA to reveal their family secrets.
They discovered that there is just a single species of squid with no population structure.
The findings [...]

ABSTRACT: I like thinking about the metaphor of hearts being broken, because what everyone thinks of [...]
New Scientist may have uncovered the bones of Richard III, the king either most villainous or most misunderstood of Plantangenet:
What exactly has been found?
The body of an adult male has been excavated from what is believed to be ruins of the choir area of the Grey Friars church in Leicester. It’s now a car park in the city [...]
Tecca reports on the 50 percent mutation rate in insects near the nuclear site:
Tens of thousands of residents were displaced and officials assured the world that the release of harmful radiation posed little threat. Now a new paper published in Scientific Reports has found that this is likely far from the truth, as at least one species of butterfly [...]
