Researchers have found that female red squirrels showed high levels of multimale mating and would even mate with males that had similar genetic relatedness, basically mating with their relatives.

Researchers from the University of Alberta, in Edmonton, Alberta, Canada and the University of Sheffield in Sheffield, England, United Kingdom studied a population of red squirrels over a period of three years near Kluane National Park in southwest Yukon.

While males mating with multiple females is quite common in the animal kingdom, females that multi-mate is much harder to explain.

A new discovery by University of Western Ontario scientist Graham Thompson claims to be conclusive evidence that the 'selfish gene', introduced conceptually in 1976 by British biologist Richard Dawkins, isn't just accepted as a natural extension to the works of Charles Darwin, but is now confirmed.

In studying genomes, the word 'selfish' does not refer to the human-describing adjective of self-centered behavior but rather to the blind tendency of genes wanting to continue their existence into the next generation. Ironically, this 'selfish' tendency can appear anything but selfish when the gene does move ahead for selfless and even self-sacrificing reasons.

For instance, in the honey bee colony, a complex social breeding system described as a 'super-organism,' the female worker bees are sterile. The adult queen bee, selected and developed by the worker bees, is left to mate with the male drones.

CALGARY, Alberta, June 20 /PRNewswire/ -- Oncolytics Biotech Inc. ("Oncolytics") (TSX:ONC, NASDAQ:ONCY) announced today that following U.S. Food and Drug Administration (FDA) review, the Company is initiating a U.S. Phase 2 clinical trial using intravenous administration of REOLYSIN(R) in combination with paclitaxel and carboplatin in patients with advanced head and neck cancers. The Principal Investigator is Dr. Monica Mita of the Cancer Therapy and Research Center, University of Texas Health Science Center in San Antonio, Texas (CTRC at UTHSCSA).

Dr. Ira Sharlip, President of the International Society for Sexual Medicine (ISSM) detailed a new definition of premature ejaculation. He addressed the audience of the American Urological Association during the ‘late breaking science forum’, a session designed by AUA to premier newsworthy developments in clinical urology.

The ISSM convened a panel of world experts who met in Amsterdam in the fall of 2007. Each of the 21 members of the panel was selected through a peer review process for their expertise in ejaculatory physiology, pharmacology and dysfunction. The panelists were tasked with creating a new definition of premature ejaculation (PE) based on currently available clinical evidence. Definitions of PE have previously been based on group consensus and not meeting new standards for evidence-based medicine. These definitions of PE include the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV, 2002) and the AUA definition of (2005).

Dice-size crumbs of bright material have vanished from inside a trench where they were photographed by NASA's Phoenix Mars Lander four days ago, convincing scientists that the material was frozen water that vaporized after digging exposed it.

"It must be ice," said Phoenix Principal Investigator Peter Smith of the University of Arizona, Tucson. "These little clumps completely disappearing over the course of a few days, that is perfect evidence that it's ice. There had been some question whether the bright material was salt. Salt can't do that."

The chunks were left at the bottom of a trench informally called "Dodo-Goldilocks" when Phoenix's Robotic Arm enlarged that trench on June 15, during the 20th Martian day, or sol, since landing. Several were gone when Phoenix looked at the trench early today, on Sol 24.

Researchers have determined that there are hundreds of biological differences between the sexes when it comes to gene expression in the cerebral cortex of humans and other primates. These findings indicate that some of these differences arose a very long time ago and have been preserved through evolution. These conserved differences constitute a signature of sex differences in the brain.

Many more obvious gender differences have been preserved throughout primate evolution; examples include average body size and weight, and genitalia design. This study, believed to be the first of its kind, focuses on gene expression within the cerebral cortex. The cerebral cortex is involved in many of the more complex functions in both humans and other primates, including memory, attentiveness, thought processes and language.
