Variation in facial shape is an easy way to explain phenotypes in humans to people who don't understand biology all that well. Monozygotic twins have almost identical faces and siblings usually have more similar faces than unrelated people, implying our facial morphology is under genetic regulation - but still little has been known about the genetic basis of normal human facial morphology. 

Here is a diet plan that requires no special meal purchases or even exercise, it just requires a willingness to believe that correlation-causation arrows fly backwards.  People, especially women, who read food labels are thinner.

The results of surveys on the relationship between reading food labels and obesity indicated that the body mass index of those consumers who read the label is 1.49 points lower than those who don't read food labels when shopping for food. This translates as a reduction of almost 9 lbs. for an American woman 5 feet 3 inches tall weighing 163 lbs - already obese.

How cheaply can you build a supercomputer?  A group from the University of Southampton just made one using 64 Raspberry Pi ARM GNU/Linux boxes ($25 each) and Lego blocks. The machine, named "Iridis-Pi" after the University's Iridis supercomputer, runs off a single 13 Amp mains socket and uses MPI (Message Passing Interface) to communicate between nodes using Ethernet.

The team was led by Professor Simon Cox and included Richard Boardman, Andy Everett, Steven Johnston, Gereon Kaiping, Neil O'Brien, Mark Scott and Oz Parchment.  Professor Cox's son, six-year-old James Cox, assisted with specialist support on Lego and system testing.

A set of fossil footprints in Joggins, Nova Scotia have been identified as the world’s smallest - among vertebrates to-date, anyway.

The footprints were found at Joggins Fossil Cliffs. A fossil specimen of the ichnogenus Batrachichnus salamandroides was collected by local amateur paleontologist Gloria Melanson, daughter of Don Reid, the famed Keeper of the Joggins Cliffs, while walking the Joggins beach. Joggins Fossil Cliffs is a UNESCO World Heritage Site.

When Western scrub jays summon others to screech over the body of a dead jay, they come a'runnin', and those 'funerals' can last for up to half an hour.

But why? Western scrub jays live in breeding pairs and are not particularly social birds. “They’re really territorial and not at all friendly with other scrub-jays,”  said Teresa Iglesias, a U.C. Davis graduate student and co-author of a new study in Animal Behaviour. It turns out that death seems to signify danger, which opens up an even odder set of questions.

Researchers have discovered how to store diverse forms of artificial short-term memories - in isolated brain tissue.

Memories are often grouped into two categories: declarative memory, the short and long-term storage of facts like names, places and events; and implicit memory, the type of memory used to learn a skill like playing the piano.  In the study, researchers sought to better understand the mechanisms underlying short-term declarative memories such as remembering a phone number or email address someone has just shared.
