The latest ESA Earth Observation data show that reports of the demise of the ozone hole appearing annually above Antarctica have been greatly exaggerated.
The ozone hole is normally at its largest in September, but 2002 saw it at its smallest extent for more than a decade: 40% down on previous years. And a year ago yesterday ongoing satellite measurements of ozone - gathered by the Royal Dutch Meteorological Institute (KNMI) from the Global Ozone Monitoring Experiment (GOME) instrument on ESA’s ERS-2 satellite - showed it splitting in two.
“Using GOME we have gathered global stratospheric ozone data over the last eight years,” said Henk Eskes of KNMI. “And last year we were actually able to accurately predict the split a few days before it happened, as we were operating an ozone forecasting service.”

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...

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
