The effect is to frequency of citation in their journals, raising the journal rankings used to support claims of prestige and importance.

 | ...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.

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).

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.

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.

 | ...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.

Their study suggests that stronger efforts should be made to recruit women subjects in population and clinical studies in order to find out why this gender difference exists.

The repeatability of gene loss in populations of separate origin suggests that evolutionary patterns operate at the genetic level, with parental gene loss possibly linked to changes in chromosome structure.

Meantime, foreign competitors invested heavily to challenge the once dominant global position of the United States in science, innovation, and higher education.

By allowing for the reuse of short, efficient sounds, listeners can easily disambiguate with the help of context.

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.

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... |

How the minute steps of evolution produced these constructions has long puzzled scientists, and provided a favorite target for creationists.

 | ...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... |

The right fusiform gyrus then appears to use that information to make a quick, categorical decision of whether the object is, indeed, a face.

Using common carbon fiber, scientists have discovered a one-step chemical process that is markedly simpler than established techniques for making graphene quantum dots, tiny specks of matter with properties expected to prove useful in biomedical, electronic, and optical applications.
The work was performed in the Rice University laboratory of materials scientist Pulickel Ajayan, in collaboration with colleagues in China, India, Japan and the Texas Medical Center.

Geologists estimate that the mercury released then could have been up to 30 times greater than today’s volcanic activity, making the event truly catastrophic.

Robotic surgery has the potential for new and less invasive procedures. For some, such as prostate surgery, robots are already standard practice. In addition, robotic telesurgery, operated by a surgeon from a remote location, offers the potential for better access to expert care in remote areas and the developing world.... |
