Scientifically engineered tissues intended to repair or regenerate damaged or diseased human tissues require three-dimensional tissue constructs that are densely packed with living cells.

The Bio-P3, an innovative instrument able to pick up, transport, and assemble multi-cellular microtissues to form larger tissue constructs is described in an article in Tissue Engineering, Part C: Methods.

A new mathematical analysis tool can numerically describe the skull as an extended network structured in ten modules. 

Anatomical Network Analysis (AnNA) is based on network analysis mathematical tools for studying anatomy and has led to several studies of both the human skeleton and of the rest of terrestrial vertebrates, especially in regard to the development and evolution of the skull.

Over the long term, a high-fat diet is bad for heart attack risk. Yet a new study finds that if you are going to have a heart attack, you are likely to get through it better if you ate a high-fat diet before it happened. Mice fed a high-fat diet for one day to two weeks days before a heart attack had heart attack reduced by about 50 percent. If the results could be translated to humans, that would mean piling on cheeseburgers and ice cream for a month to a year, not a winning strategy for lots of other reasons.

It's another example of the obesity paradox, an unexplained phenomenon where obese patients who do have a heart attack live longer than thin ones.

Researchers at the Medical College of Wisconsin (MCW), in collaboration with other colleagues of the Genetic Epidemiology of Lung Cancer Consortium (GELCC), have identified a gene that is associated with lung cancer.

The findings are published in American Journal of Human Genetics. Through whole exome sequencing, researchers identified a link between a mutation in PARK2, a gene associated with early-onset Parkinson's disease, and familial lung cancer.

The researchers sequenced the exomes (protein coding region of the genome) of individuals from a family with multiple cases of lung cancer. They then studied the PARK2 gene in additional families affected by lung cancer.

For chimpanzees, just like humans, teasing, taunting and bullying are familiar parts of playground politics. An analysis of 12 years of observations of playground fights between young chimpanzees in East Africa finds that chimps with higher-ranked moms are more likely to win.

The results come from an analysis of daily field notes recorded from 2000 to 2011 at Gombe National Park in western Tanzania. Stored in the Jane Goodall Institute Research Center at Duke University and also at The George Washington University, the records are part of a larger database containing more than 50 years of data on over 300 wild chimpanzees, going all the way back to Jane Goodall's first observations from the early 1960s.

It's always helpful to have text or verbal claims about where a video was taken, but when it comes to terrorists or other criminals, they might not be telling the truth. 

Researchers from Ramón Llull University in Spain have created a system capable of geolocating videos by comparing audiovisual content with a worldwide multimedia database and it is able to locate where the videos were taken with no indication of where they were produced.
