The Moderate Resolution Imaging Spectrometer (MODIS) instrument aboard NASA's Terra captured a visible image of Hurricane Rafael in the North Atlantic on Oct. 17 at 1440 UTC (10:40 a.m. EDT). Although Rafael was far from land, its northwestern fringe clouds were brushing Nova Scotia, Canada.

By 5 p.m. EDT on Oct. 17, Rafael had become extra-tropical, meaning that its core changed from a warm system to a cold system, just like a typical mid-latitude low pressure system. At that time, Rafael had maximum sustained winds near 75 mph (120 kph). It was centered near 40.2 North latitude and 56.5 West longitude, about 475 miles (750 km) southeast of Halifax, Nova Scotia, Canada. Rafael was moving to the northeast at 35 mph (56 kph). Turn toward the east-northeast with some increase in forward speed later today, Oct 18.
The National Hurricane Center noted that ocean swells generated by the cyclone are expected to affect the coast of eastern Canada during today and tomorrow. These swells are likely to cause life-threatening surf and rip currents.
By 5 p.m. EDT on Oct. 18, the cold front was found to be merged with the tropical cyclone, making it extra-tropical. Rafael is expected to complete a cyclonic loop around a deep-layer low over the north-central Atlantic day or two and ride into hurricane history.

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...
