Scientists carrying out a major epidemiological study at Karolinska Institutet and Uppsala University have discovered that there is no clear correlation between routine ultrasonic scans and intellectual impairment.
“Fears have been expressed that sonography can lead to diminished intellectual capacity,” explains Helle Kieler, research scientist at Karolinska Institutet.
Previous epidemiological studies have shown that young men who had been exposed to in utero ultrasonic scans are more likely than other young men to be left handed; and that there is a correlation between left-handedness and reduced intellectual capacity in children born after a complicated pregnancy.

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...
