A small but significant proportion of morbidly obese people are missing a section of their DNA, according to research published February 3 in Nature. The authors of the study, from Imperial College London and ten other [...]
Abandoned Detroit Home Encased In Ice
An Icey New Idea
An abandoned home has been encased in ice in an effort to draw attention to the housing crisis in the US.
Gregory Holm, a photographer, and Matthew Radune, a New York architect, picked a house in Detroit which had been slated for demolition, from the state’s land bank.
In return, they agreed to pay [...]
Forests Are Growing Faster, Ecologists Discover; Climate Change Appears to Be Driving Accelerated Growth
Forest in Maryland.
Speed is not a word typically associated with trees; they can take centuries to grow. However, a new study in the Proceedings of the National Academy of Sciences has found evidence that forests in the Eastern United States are growing faster than they have in the past 225 years. The study offers a [...]

Rotting Fish Heads: Novel Studies of Decomposition Shed New Light on Our Earliest Fossil Ancestry
These are three rotting fish heads.
Decaying corpses are usually the domain of forensic scientists, but palaeontologists have discovered that studying rotting fish sheds new light on our earliest ancestry.
New Adhesive Device Could Let Humans Walk on Walls
Paul Steen and Michael Vogel’s surface tension-based adhesive device with a lego man payload.
Could humans one day walk on walls, like Spider-Man? A palm-sized device invented at Cornell that uses water surface tension as an adhesive bond just might make it possible.
ATM Skimmers: Part 2
In PART 1 of this series, we saw the first round of what seems to be turning into a dastardly trend. Now, Brian Krebs continues to scare the pants off of us with his ongoing series on sophisticated ATM skimmers (devices that capture your card number, working with a hidden camera to catch your PIN). [...]
