Height may point to a biological basis for pedophilia, according to new research released by the Centre for Addiction and Mental Health (CAMH). The study found that pedophilic males were shorter on average than males without a sexual attraction to children.

RV Polarstern on its way to East Siberian Sea
Bremerhaven, August 19th 2008. German research vessel Polarstern, operated by the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association, transits the Northwest Passage for the first time. Polarstern left the port of Reykjavik on August 12th, sailed around Greenland on a southern course and is located right in the Northwest Passage. Its destination is the East Siberian Sea where geoscientific measurements at the junction between the Mendeleev Ridge and the East Siberian Shelf are at the focus of the participants of this expedition. The measurements striven for in the framework of the International Polar Year shall help to understand how the undersea ridges and basins were built. This expedition takes the researchers in 68 days around the North Pole because the return voyage is to lead via the Northeast Passage.
Robot with a Biological Brain: new research provides insights into how the brain works
(PhysOrg.com) -- A multidisciplinary team at the University of Reading has developed a robot which is controlled by a biological brain formed from cultured neurons. This cutting edge research is the first step to examine how memories manifest themselves in the brain, and how a brain stores specific pieces of data. The key aim is that eventually this will lead to a better understanding of development and of diseases and disorders which affect the brain such as Alzheimer's Disease, Parkinson's Disease, stroke and brain injury.
Microbes, by latitudes and altitudes, shed new light on life's diversity
Microbial biologists, including the University of Oregon's Jessica L. Green, may not have Jimmy Buffett's music from 1977 in mind, but they are changing attitudes about evolutionary diversity on Earth, from oceanic latitudes to mountainous altitudes.

Short arms and legs linked to risk of dementia
People with shorter arms and legs may be at a higher risk for developing dementia later in life compared to people with longer arms and legs, according to a study published in the May 6, 2008, bonus issue of
Neurology, the medical journal of the American Academy of Neurology. Researchers say the association between short limbs and dementia risk may be due to poor nutrition in early life, which can affect limb growth.
One virtual step for man, one real leap for mankind
Imagine being able to take a step back in time and walk through the streets of ancient Pompeii hours before the eruption of Vesuvius. In April 2008, European researchers will demonstrate that walking through virtual environments is set to be a reality.
Wee genes make tall story
Scientists are beginning to develop a clearer picture of what makes some people stand head and shoulders above the rest. The team of Exeter researchers who last year identified the first common version of a gene influencing height has now identified a further 20 regions of the genome which together can make a height difference of up to 6cm.
