What is the latest recipe for anti-matter?  Take a gold sample the size of the head of a push pin, shoot a laser through it, and suddenly more than 100 billion particles of anti-matter appear.  The anti-matter, also known as positrons, shoots out of the target in a cone-shaped plasma "jet."

This new ability to create a large number of positrons in a small laboratory opens the door to several fresh avenues of anti-matter research, including an understanding of the physics underlying various astrophysical phenomena such as black holes and gamma ray bursts.  Anti-matter research also could reveal why more matter than anti-matter survived the Big Bang at the start of the universe.

Researchers dated remains from four multiple burials discovered in Germany in 2005 and found that the 4,600-year-old graves contained groups of adults and children buried facing each other – an unusual practice in Neolithic culture.  One of the graves was found to contain a female, a male and two children. Using DNA analysis, the researchers established that the group consisted of a mother, father and their two sons aged 8-9 and 4-5 years: the oldest molecular genetic evidence of a nuclear family in the world (so far).

The burials, discovered and excavated at Eulau, Saxony-Anhalt, were also unusual for the great care taken in the treatment of the dead. The remains of thirteen individuals were found in total, all of whom had been interned simultaneously.

150 years ago it was discovered that the speech center is in the left cortex  and since then functional differences between left and right hemisphere have become well known; language is mainly handled by the left hemisphere while spatial recognition is more specialized to the right hemisphere.

However, the structural differences of synapses underlying left-right difference of the brain have remained unknown. Now a research team led by Prof Ryuichi Shigemoto at the National Institute for Physiological Sciences in Japan, and colleagues have found that synaptic size and shape in the center of the spatial memory (i.e. hippocampus) were asymmetrical between synapses receiving input from the left and right hemisphere.

Water vapor is known to be Earth's most abundant greenhouse gas, but the extent of its contribution to global warming has been diminished by attention on the economic/political millstone of western civilization carbon dioxide. Using recent NASA satellite data, researchers have estimated more precisely than ever the heat-trapping effect of water in the air, validating the role of the gas as a critical component of climate change.

Andrew Dessler and colleagues from Texas A&M University in College Station confirmed that the heat-amplifying effect of water vapor is potent enough to double the climate warming caused by increased levels of carbon dioxide in the atmosphere. 

Asthma may be overdiagnosed in countries like Canada, suggests a longitudinal study of 540 obese and non-obese adults (http://www.cmaj.ca/press/pg1121.pdf)that found approximately one third of Canadians with physician-diagnosed asthma do not have asthma when objectively tested.

Why do so many people give up on those New Year's resolutions to lose weight or curb luxury spending? A new study in the Journal of Consumer Research says it has to do with the way our goals intersect with our natures and it uncovers some important differences in the way people categorize "necessities" and "luxuries.".

The study by authors Cait Poynor (University of Pittsburgh) and Kelly L. Haws (Texas A&M University) is one of the first to try to understand why some people have more trouble than others regulating behaviors.
