Prenatal exposure to air pollutants in New York City can adversely affect child development, according to the results of a study released today by the Columbia Center for Childrens Environmental Health (CCCEH) at Columbia Universitys Mailman School of Public Health. Previous studies have shown that the same air pollutants can reduce fetal growth (both weight and head circumference at birth), but this study, which examined a group of the same children at three years of age, is the first to reveal that those pollutants can also affect cognitive development during childhood.
The study will be published online Monday, April 24, 2006, and can be accessed at the following URL: http://www.ehponline.org/docs/2006/9084/abstract.html.
Investigators at the Center studied a sample of 183 three-year-old children of non-smoking African-American and Dominican women residing in the neighborhoods of Washington Heights, Central Harlem, and the South Bronx. They found that exposure during pregnancy to combustion-related urban air pollutants known as polycyclic aromatic hydrocarbons (PAHs) were linked to significantly lower scores on mental development tests and more than double the risk of developmental delay at age three. Such delay in cognitive development is indicative of greater risk for performance deficits in language, reading, and math in the early school years.

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
