Are we more risk averse as we get older? It’s a gray (matter) area, research finds

Age itself is not the determining factor in how an individual views or tolerates risk when making decisions; instead, it is the age-related decline in the volume of gray matter in our brains, research shows.

Public skepticism would likely greet a new Zika vaccine, study says

As scientists race to create a vaccine for the Zika virus, new research suggests almost half of Americans wouldn’t be interested in getting the shot even if public health officials recommended it for them.

Tomato plant’s male reproduction organs shrivel under high temperatures

The male reproduction organs of tomato plants cannot cope with high temperatures. When temperatures rise above 32 degrees Celsius for several consecutive days, their appearance changes and they produce less and less fertile pollen, leading to lower agricultural yields.

Using herpes drugs to slow down Alzheimer’s disease could become reality

The first clinical study to investigate if herpes virus drugs can have an effect on fundamental Alzheimer’s disease processes has been launched. The research group has previously demonstrated a correlation between herpes virus infection and an increased risk of Alzheimer’s disease.

Estimating the Relative Water Content of Single Leaves from Optical Polarization Measurements

Abstract: Remotely sensing the water status of plants and the water content of canopies remain long-term goals of remote sensing research. For monitoring canopy water status, existing approaches such as the Crop Water Stress Index and the Equivalent Water Thickness have limitations. The CWSI does not work well in humid regions, requires estimates of the vapor pressure deficit near the canopy during the remote sensing over-flight and, once stomata close, provides little information regarding the canopy ...

Digital Beamforming Synthetic Aperture Radar Developments at NASA Goddard Space Flight Center

Abstract: Advanced Digital Beamforming (DBF) Synthetic Aperture Radar (SAR) technology is an area of research and development pursued at the NASA Goddard Space Flight Center (GSFC). Advanced SAR architectures enhances radar performance and opens a new set of capabilities in radar remote sensing. DBSAR-2 and EcoSAR are two state-of-the-art radar systems recently developed and tested. These new instruments employ multiple input-multiple output (MIMO) architectures characterized by multi-mode operation, s...

ISS Daily Summary Report – 12/13/2016

HII Transfer Vehicle (HTV)-6 Capture/Berthing: This morning, the crew captured HTV-6 at 4:37 am CST using the Space Station Remote Manipulator System (SSRMS). Following capture, Robotics Ground Controllers used the SSRMS to maneuver the HTV-6 into position to support the inspection of the HTV-6 Passive Common Berthing Mechanism (CBM) and maneuver the HTV-6 to the N2 Nadir install position.  Ground Controllers the completed the N2 nadir CBM capture and bolting to complete the HTV installation.  Following installation, the crew pressurized the vestibule, performed vestibule outfitting, and ingressed the vehicle. The Robotic Ground Controllers have released the HTV6 and maneuvered the SSRMS to grapple the HTV6 External Platform (EP). Here, HTV Berthing Camera System (HBCS) was checked out on both strings and SSRMS is now providing power to the EP for heaters on 1 string (camera and batteries). Lighting Effects: The crew performed a visual assessment tests in the Crew Quarters (CQs), using the newly installed Solid State Lighting Assemblies (SSLAs) and hope to better quantify and qualify how lighting can effect habitability of spacecraft.  The light bulbs on the ISS are being replaced with a new system designed for improved crew health and wellness. The Testing Solid State Lighting Countermeasures to Improve Circadian Adaptation, Sleep, and Performance During High Fidelity Analog and Flight Studies for the International Space Station (Lighting Effects) investigation studies the impact of the change from fluorescent light bulbs to solid-state light-emitting diodes (LEDs) with adjustable intensity and color and aims to determine if the new lights can improve crew circadian rhythms, sleep, and cognitive performance. Results from this investigation also have major implications for people on Earth who use electric lights.  Microgravity Science Glovebox (MSG) Laptop Computer (MLC) Shell Swap: During Packed Bed Reactor Experiment (PBRE) operations, ground teams observed power and connectivity issues with the MLC.  The crew performed a shell swap, removing the internal components and installing them in a backup laptop shell.  Following the swap, ground teams observed connectivity issues, and the crew was instructed to verify connection to the power brick a power cycle which recovered the MLC.  No loss of science was reported during the MLC recovery and PBRE proceeded to downlink files after the recovery. PBRE studies the behavior of gases and liquids when they flow simultaneously through a column filled with fixed porous media. The porous media or “packing” can be made of different shapes and materials and are used widely in chemical engineering as a means to enhance the contact between two immiscible fluid phases (e.g., liquid-gas, water-oil, etc.). Packed columns can serve as reactors, scrubbers, strippers, etc. in systems where efficient interphase contact is desired, both on Earth and in space.  Today’s Planned Activities All activities were completed unless otherwise noted.
