    Researchers at Sanford Burnham Prebys Medical Discovery Institute (SBP) today announced 6 boxes of fruit flies (Drosophila melanogaster) will travel to the International Space Station (ISS) to study the impact of weightlessness on the heart. The fruit flies are scheduled to launch on June 1, 2017, from NASA’s Kennedy Space Center and will travel to the ISS via a SpaceX Dragon spacecraft.

    Living in zero gravity is known to negatively impact the body’s cardiovascular system...

    1. MOPA laser module for MAIUS Hybrid-integrated master-oscillator power-amplifier (MOPA) laser module for rubidium precision spectroscopy in space developed by the Ferdinand-Braun-Institut – three of these MOPA modules along with two redundant modules are integrated into the laser system.

FBH’s laser modules are integrated on the bottom side of the heat sink, the top side houses modules for further processing of the light to be transferred to the main experiment.

    a-d) Whole-body imaging of the osterix-DsRed transgenic line. The left-side images show the same ground control at day 1; and the right-side images, the same flight medaka at day 1. Arrows point to the head and fin region. All images show ventral views. Montage images were made from 6 captured optical images, divided by dotted lines (a,b). The white region shows an osterix-DsRed fluorescent signal. Embedded views show the enlarged head region (c,d). (e) The fluorescent intensity from day 1 to 7 of observation day constantly increased in the flight group. (f-h) The representative visualizing data for osterix-DsRed/TRAP-GFP in the flight group. All images show ventral views in the head region. (i-l) The merged images were captured by 3D views for osterix-DsRed and TRAP-GFP in the pharyngeal bone region of the double transgenic line. The pharyngeal bone region in the ground control (i) or the flight (k) group at day 4. The image for TRAP-GFP in the pharyngeal bone region of "i" (j) or "k" (l). lp, lower pharyngeal bone; c, cleithrum. GFP signals identify osteoclasts (OC). Credit: Tokyo Institute of Technology

    Researchers in Japan have examined cucumber seedlings germinated under the very weak gravity – or microgravity – conditions of the International Space Station. Plants are experts in survival and can control the direction of their roots to maximize the use of resources around them. Using specialized cells, they can sense gravity and redistribute hormones, called auxins, to stimulate growth and allow vital features of the plant to develop...
