Researchers have identified an astounding 4,000 distinctive proteins in human blood plasma, a critical step toward cataloging biological markers for early diagnosis of cancer and other diseases.
"This is 10 times the number of proteins identified" and previously reported, said Richard D. Smith, a senior scientist and Battelle Fellow at the Department of Energys Pacific Northwest National Laboratory. The proteomics advance was announced Saturday at the American Association for the Advancement of Science annual meeting.
"Because there is huge interest in determining their utility as biomarkers for different diseases, I want to emphasize the large numbers of proteins now identified in plasma," said Smith, a Battelle Fellow at PNNL and director of the National Institutes of Health Proteomics Research Resource Center at PNNLs Richland, Wash., campus.

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.

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...
