The wood siding could age badly unless it's well-treated, but otherwise cool.

After the devastating earthquake in Amatrice, Italy, on August 24th, the Vigili del Fuoco (Italian fire brigade) requested assistance from the TRADR (Long-Term Human-Robot Teaming for Robot-Assisted Disaster Response) project (EU FP7 framework, grant No. 60963). TRADR deployed two Unmanned Ground Vehicles (UGVs) and three Unmanned Aerial Vehicles (UAVs) to assist the post-earthquake response in Amatrice.
The task was to use robots to provide 3D textured models of two churches, San Francesco and Sant’ Agostino, national heritage monuments from the XIVth century. Both were in a state of partial collapse and in need of shoring to prevent potential further destruction. The models should serve to plan the shoring operations and to assess the state of various objects of cultural value inside the churches, such as valuable frescos.
The UGVs successfully entered the San Francesco church, teleoperated entirely out of line of sight and partially in collaboration. For part of the mission, one UGV provided a view of the other one to enable maneuvering in very constrained space with low connection bandwidth. One of the UGVs operated in the church continuously for four hours. A UAV was also present for a short time in parallel and provided additional views of the UGVs.
Why do we not discuss clouds more?
I mean look at that. That’s water.
Flying water.
FLYING
FUCKING
WATER
LIKE WHAT THE FUCK, WHY DO WE EVER STOP TALKING ABOUT THIS
WHAT IS THIS
HOW IS THIS EVEN
AND NOW THE FLYING WATER IS EATING A MOUNTAIN
GOD DAMN, WHAT
Each month, we highlight a different research topic on the International Space Station. In August, our focus is biological research. Learning how spaceflight affects living organisms will help us understand potential health risks related to humans on long duration missions, including our journey to Mars.
Cells, microbes, animals and plants are affected by microgravity, and studying the processes involved in adaptation to spaceflight increases our fundamental understanding of biological processes on Earth. Results on Earth from biological research in space include the development of new medications, improved agriculture, advancements in tissue engineering and regeneration, and more.
Take a look at a few of the biological research experiments performed on space station:
Biomolecule Sequencer
Living organisms contain DNA, and sequencing DNA is a powerful way to understand how they respond to changing environments. The Biomolecule Sequencer experiment hopes to demonstrate (for the first time) that DNA sequencing is feasible in an orbiting spacecraft. Why? A space-based DNA sequencer could identify microbes, diagnose diseases and understand crew member health, and potentially help detect DNA- based life elsewhere in the solar system.
Ant-stronauts
Yes, ant-stronauts…as in ants in space. These types of studies provide insights into how ants answer collective search problems. Watching how the colony adapts as a unit in the quest for resources in extreme environments, like space, provides data that can be used to build algorithms with varied applications. Understanding how ants search in different conditions could have applications for robotics.
TAGES
The TAGES experiment (Transgenic Arabidopsis Gene Expression System) looks to see how microgravity impacts the growth of plant roots. Fluorescent markers placed on the plant’s genes allow scientists to study root development of Arabidopsis (a cress plant) grown on the space station. Evidence shows that directional light in microgravity skews root growth to the right, rather than straight down from the light source. Root growth patters on station mimic that of plants grown at at 45% degree angle on Earth. Space flight appears to slow the rate of the plant’s early growth as well.
Heart Cells
Spaceflight can cause a suite of negative health effects, which become more problematic as crew members stay in orbit for long periods of time. Effects of Microgravity on Stem Cell-Derived Cardiomycytes (Heart Cells) studies the human heart, specifically how heart muscle tissue contracts, grows and changes in microgravity. Understanding how heart muscle cells change in space improves efforts for studying disease, screening drugs and conducting cell replacement therapy for future space missions.
Medaka Fish
Chew on these results…Jaw bones of Japanese Medaka fish in microgravity show decreased mineral density and increased volume of osteoclasts, cells that break down bone tissue. Results from this study improve our understanding of the mechanisms behind bone density and organ tissue changes in space.
These experiments, and many others, emphasize the importance of biological research on the space station. Understanding the potential health effects for crew members in microgravity will help us develop preventatives and countermeasures.

I dance the Waltz to look refined. I dance Salsa to look exotic. I dance the Tango to look sexy. I dance Blues to look sexual. I dance West Coast Swing to look smooth. And I dance Lindy Hop so I can stop worrying what I look like and just have fun bouncing and swirling like a deranged yo-yo.
If This Isn’t From a Book, It Should Be (via gaircyrch)
I’d argue that Westie looks like what ever you want it to be (I dance it because I love how free I feel)
Gaming, Science, History, Feminism, and all other manners of geekery. Also a lot of dance
