New York Times explores the mapping of a new genome, as researchers chart a family tree of craft beer:

After thousands of years of unwitting domestication, brewing yeasts — the microorganisms that ferment a brewer’s tepid slop of grain, water and hops into beer — are as diverse as the beer they make. And now [...]

Nature introduces yet another ethical wrinkle into the production of stem cells, with new techniques to create cell-generating embryos from adult cells:

On 17 April, researchers led by Young Gie Chung and Dong Ryul Lee at the CHA University in Seoul reported in Cell Stem Cell that they had cloned embryonic stem-cell (ES cell) [...]

Nature reveals how parents who live through something horrible can have children who inherit depression and anxiety – biologically, through their RNA – from traumas they never personally experienced:

A study published this week in Nature Neuroscience finds that stress in early life alters the production of small RNAs, called microRNAs, in the sperm of [...]

Science Daily tries to find the evolutionary roots of …oooh, shiny! I’ll finish this tomorrow:

From an evolutionary standpoint, impulsivity makes sense: Our ancestors should have been inclined to seek immediate rewards when the next day was uncertain.

Procrastination, on the other hand, may have emerged more recently in human history. In the modern world, [...]

Science Daily twists the archaeological order of things around a little. Humans came out of Africa, humans in Africa have domesticated cattle for thousands of years, the easy assumption is that cattle were first domesticated in Africa and kind of moved out with us into the Fertile Crescent, where they helped us settle down and [...]

Nature examines a DNA test on a “Clovis boy,” whose DNA proves that 12,000 years ago, the ancestors of today’s Native Americans were already here:

…[T]he boy’s genome sequence shows that today’s indi­genous groups spanning North and South America are all descended from a single population that trekked across the Bering land bridge from Asia [...]

Shades of Philip Larkin…. Washington Post has more on how mice, at least, pass fear down with their DNA:

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 [...]

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 [...]

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 [...]
