Learning a second language is usually difficult and often when we speak it we cannot disguise our origin or accent. However, there are important differences between individuals with regard to the degree to which a second language is mastered, even for people who have lived in a bilingual environment since childhood.

''Henry Grays Anatomy of the Human Body" - Gray's Anatomy, as it is commonly called, is among the most iconic scientific books ever published: an illustrated textbook of anatomy that is still a household name 150 years since its first edition, known for its rigorously scientific text and masterful illustrations as beautiful as they are detailed.

First published under the title "Grays Anatomy: Descriptive and Surgical" in 1858, Gray would not live to see its full impact.    He contracted smallpox from his nephew and died in 1861 at the age of 34.

China's farmers and merchants should take advantage of new agricultural and business opportunities that could help mitigate some effects of the annual flooding behind the Three Gorges Dam on the Yangtze River, according to an Ohio State University wetland expert. The level of water in the reservoir behind the dam will top off at 575 feet above sea level during the coming winter. The reservoir pool, covering abandoned cities, houses and farm fields formerly populated by an estimated 1.5 million people, will extend over 400 square miles – equivalent to the land area of Hong Kong.

Today, scientists from Procter&Gamble (P&G), the University of Calgary and the University of Virginia announced results from the first study to examine the entire human genome's response to the most common cold virus, human rhinovirus.

A wish could come true for paraplegics who play the piano and are paralyzed from the hips down: Heidelberg researcher Dr.-Ing. Rüdiger Rupp has developed a method with which a pianist can operate the right pedal of a concert grand wirelessly – a first in the world. A paraplegic pianist can thus overcome the handicap of being able to play the piano using only his arms and hands.

Dr. Rupp, director of the research department at the spinal cord injury unit of the Orthopedic Clinic of Heidelberg University Hospital (Director: Prof. Dr. Hans Jürgen Gerner), was honored for this invention with € 15,000 from the Innovation Award 2008 of the German Paraplegic Foundation (DSQ).

Genetically, the Germans and British are very close to each other but the genetic distances between the Swedes and Eastern and Western Finns are larger, and the diversity in these populations is lower.

A recent study shows that genetic differences in Central Europe appear smaller than between and even within North European populations.    The study, led by researcher Päivi Lahermo from Institute for Molecular Medicine Finland (FIMM) and University of Helsinki, Finland, and professor Juha Kere from Karolinska Institutet, Sweden.

The understanding of genetic variation in human populations is important not only for obtaining information on population history, but also for successful studies of genetic factors behind human diseases, says Juha Kere.
