How Settler Farmers Fathered Europe's Males
From The Independent:
They came, they saw, they farmed and then they stole our women. Stone age farmers from the middle east not only brought their agricultural know-how with them to western Europe, they settled down with the local womenfolk and had children.
A genetic analysis of present-day male Europeans has revealed that the first farmers spread both their agricultural technology and their genes across the continent, out-competing the resident hunter-gatherer males for female attraction.

No Bananas On My Space Flight
Astronauts experience weightlessness, and most of them also lose weight in space. Why? Because they are often nauseous, always busy, and the food on board their capsules, shuttles and space stations doesn't look, smell or taste like it does on Earth.
As a result, NASA has devoted years to creating foods that can travel safely into space and meet astronauts' nutritional needs while not making a mess of their spacecraft.

Hexapod Robot Moves In The Right Direction By Controlling Chaos
From Scientific American:
Given that robots generally lack muscles, they can't rely on muscle memory (the trick that allows our bodies to become familiar over time with movements such as walking or breathing) to help them more easily complete repetitive tasks. For autonomous robots, this can be a bit of a problem, since they may have to accommodate changing terrain in real time or risk getting stuck or losing their balance.
