Huntsville, AL, USA. Some of the editors at professional journals coerce authors into adding unnecessary citations to articles in the same journal that is considering publishing the submitted work.
The effect is to frequency of citation in their journals, raising the journal rankings used to support claims of prestige and importance.

 TS-Si News Service Wednesday, 01 February 2012 Melbourne, Victoria, Australia. It takes 24 million generations for a mouse-sized animal to evolve to the size of an elephant, according to new findings that describe increases and decreases in mammal size following the extinction of the dinosaurs 65 million years ago.
A team of biologists and palaeontologists discovered that rates of size decrease are much faster than growth rates, taking only 100,000 generations for very large decreases that lead to dwarfism.

 TS-Si News Service Tuesday, 31 January 2012 Charlottesville, VA, USA. Small groups of male beetles that live on the fringes of society with their buddies are less likely to meet up with females, copulate and pass on their genes to offspring, social interactions that likely influence evolution by natural selection.
Vince Formica and Butch Brodie are evolutionary biologists in the University of Virginia College of Arts & Sciences. They study the beetles in a remote forest near U.Va.'s Mountain Lake Biological Station (MLBS).

 TS-Si News Service Monday, 30 January 2012 Berkeley, CA, USA. Scientists have reported the first 3-D images of an individual protein ever obtained with enough clarity to determine its structure.
The 3-D images reported in PLoS ONE include those of a single IgG antibody and apolipoprotein A-1 (ApoA-1), a protein involved in human metabolism.

 TS-Si News Service Friday, 27 January 2012 Manchester, United Kingdom. Discovering that graphene is superpermeable with respect to water, scientists now have a material that directly addresses the design of filtration, separation or barrier membranes — and for the selective removal of water — all of which are implicated in cell biology and organ generation.

 TS-Si News Service Wednesday, 25 January 2012 East Lansing, MI, USA. Prejudice against people from groups different than their own is linked to aggression for men and fear for women, suggests new research findings.
Men throughout history have been the primary aggressors against different groups as well as the primary victims of group-based aggression and discrimination, while women live under the threat of sexual coercion by foreign aggressors and are apt to maintain a fear of strangers to protect themselves and their offspring.

 TS-Si News Service Saturday, 21 January 2012 Cambridge, MA, USA. Cognitive scientists at MIT have developed a new take on why human language has so many words with multiple meanings, claiming that ambiguity actually makes language more efficient.
By allowing for the reuse of short, efficient sounds, listeners can easily disambiguate with the help of context.

 TS-Si News Service Friday, 20 January 2012 Vienna, Austria. While the Heisenberg uncertainty principle has proven valid since it was published in 1927, new results published in the journal Nature Physics suggest the basic arguments have to be revisited.
The principle is arguably one of the most famous foundations of quantum physics, saying that not all properties of a quantum particle can be measured with unlimited accuracy.

 Akhilesh B. Reddy Thursday, 19 January 2012 Cambridge, United Kingdom. We’re all slaves to time, and that’s no understatement. I’m in a handover meeting, about to begin a weekend on-call as a doctor. The team discusses all of the patients and what the plan is for the next 48–72 hours.
From previous experience, I know that things on the wards change quickly and so this information will be out of date in the next 24 hours. But that’s the job; patients get sick and you have to react fast to make sure that they are treated effectiv

 TS-Si News Service Tuesday, 17 January 2012 Chicago, IL, USA. Small, high-probability cell mutations over time can produce complex systems called molecular machines, physical complexes of specialized proteins working together to carry out some biological function.
How the minute steps of evolution produced these constructions has long puzzled scientists, and provided a favorite target for creationists.

 TS-Si News Service Monday, 16 January 2012 Los Angeles, CA, USA. The first quantitative evidence links social behavior to the evolution of facial diversity and complexity in primates, showing that ecology controls aspects of facial patterns.
Close to the equator, the skin and hair around the eyes of primate species get darker: areas around the nose and mouth darken if they live in humid environments and denser forests. Facial hair lengthen as species live farther from the equator and the climate turns cold, which may be related to regul
