Finished sequence reveals twice as many genes, cereal similarity
Behold a grain of rice. Inside are thousands of cells; within each cell are 12 chromosomes; and on rices smallest chromosome, No. 10, are about 3,500 genes and more than 22 million base pairs, the links in the chain of DNA.
So, whats the big deal about rices smallest chromosome?
There are several, according to a report in the June 6 issue of the journal Science. Upon close examination, chromosome 10 has about twice as many genes as were predicted when an international consortium announced draft genome sequence in the same journal last December. An organisms genome consists of the entire genetic code held in its DNA.

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...
At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
