Pedophilia, the sexual attraction of adults to children, is a significant public health concern and it does not respond well to treatment. Additionally, the brain mechanisms underlying pedophilia are not well understood.
A new study being published in the September 15th issue of Biological Psychiatry is the first of its kind to use functional brain imaging to describe neural circuits contributing to pedophilia.

Submerged stone structures lying just below the waters off Yonaguni Jima are actually the ruins of a Japanese Atlantis - an ancient city sunk by an earthquake about 2,000 years ago.
That's the belief of Masaaki Kimura, a marine geologist at the University of the Ryukyus in Japan who has been diving at the site to measure and map its formations for more than 15 years.

A major advance in fertility treatment is signalled today as doctors unveil details of a technique that will allow human eggs to be grown in the laboratory from ovarian tissue samples.
A smoking gun that could snuff out a hot debate over skeletal remains dubbed "the hobbit" is in hand, literally, according to a group of scientists.
Three wrist bones provide key evidence supporting the argument that fossil remains of an ancient, undersized individual represent a new hominin species that walked the Earth with modern humans, say the study scientists.

So you find images from your new 10 Megapixel shooter clear, well here is a glimpse of the future. The above video is of 13.4 Gigapixel photo. 1 Gigapixel = 1000 Megapixels or 1 billion pixels. The photo is of Harlem, New York city, no matter where you zoom in, it's always crystal clear. It can clearly depict a person's face 20 miles away.
To help shoppers avoid mislabeled toxic pufferfish and pilots steer clear of birds, federal agencies are starting to tap into an ambitious project that is gathering DNA "barcodes" for the Earth's 1.8 million known species.
A consortium of scientists from almost 50 nations is overseeing the building of a global database made from tiny pieces of genetic material. Called DNA barcoding, the process takes a scientist only a few hours in a lab and about $2 to identify a species from a tissue sample or other piece of genetic material.

We all make mistakes and, if you believe medical scholar John Ioannidis, scientists make more than their fair share. By his calculations, most published research findings are wrong.
Dr. Ioannidis is an epidemiologist who studies research methods at the University of Ioannina School of Medicine in Greece and Tufts University in Medford, Mass. In a series of influential analytical reports, he has documented how, in thousands of peer-reviewed research papers published every year, there may be so much less than meets the eye.

In the first experiments able to mimic the crushing, searing conditions found in Earth's lower mantle, and simultaneously probe tell-tale properties of iron, scientists have discovered that material there behaves very differently than predicted by models. The research also points to the likelihood of a new zone deep in the Earth. The work is published in the September 21, 2007, issue of Science.
Surface phenomena such as volcanoes and earthquakes are generated by what goes on in Earth's interior. To understand some of these surface dynamics, scientists have to probe deep into the planet. The lower mantle is between 400 and 1,740 miles deep (650 km- 2,800 km) and sits atop the outer core.

| As depth increases in the planet, so does the temperature and pressure. In this diagram the crust and upper mantle is grey, the lower mantle is yellow, the outer is core orange, and the inner core is bright orange. The pressure between the upper and lower mantle is about 23 gigapascals or about 230,000 times atmospheric pressure at sea level. At the base of the lower mantle the pressure increases to an intense 1.35 million times sea-level pressure (135 GPa). |
MOSCOW - On the day of the 150th anniversary of the birth of Eduard Tsiolkovsky, the founder of world cosmonautics, scientists meet in Kaluga to discuss matters aimed at protecting the Earth from asteroids.
NASA has confirmed the launch date for Dawn, its mission to the asteroid belt. The space agency is aiming for a launch window that opens at 07:25 (EDT) on 26 September, and closes again 29 minutes later.
