In early September of 1666, the Great Fire of London devastated the city for four days. Archaeological evidence suggests the searing heat may have reached as high as 3000 F. At that temperature human remains, bones and all, become ash.
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.

I’d argue that Westie looks like what ever you want it to be (I dance it because I love how free I feel)
Although we now take for granted the long term success of the International Space Station, it wasn’t too long ago that we were totally earthbound. That changed on this day, October 12, 1964 when the Soviet Union launched the Voskhod 1 (Восхо́д), the first manned capsule to carry more than one person into space. The Voskhod program was a proof of concept program to test systems for more ambitious space exploration. The Voskhod program was notable for several firsts: the first multi-person mission to space (Cosmonauts Komarov, Yegorov and Feoktistov in the Voskhod 1) and the first space walk (Belyayev and Leonov in Voskhod 2). The Vostok and Voskhod programs provided the framework for what became the Soyuz program and ultimately the current ISS.
The Russian desire to ‘win’ the Space Race led to many dangerous compromises. The interior of the capsule (shown above) was so cramped that the cosmonauts would not have room for space suits, making the flight extremely dangerous in the event of depressurisation. To insure the engineers paid enough attention to this, head designer Sergei Korolev assigned the lead engineer to fly inside the capsule, therefore motivating him to design the safest capsule possible.
The Russian word Voskhod (Восхо́д) means sunrise and is a combination of the Russian words vos- (from vostok восток) meaning east and xodete (ходить) meaning go or rise.
The Indian Space Research Organisation (ISRO) just sent 20 satellites into orbit with one launch, marking the largest satellite launch in the space agency’s history.
Their previous record was 10 satellites delivered with one mission, and this latest accomplishment takes them a lot closer to the delivery rates of NASA and the Russian Federal Space Agency, solidifying India’s place in the global space market.
Out of the 20 satellites, 17 were commercial, so used by companies to help us do things like get better TV signals or weather forecasts. The main cargo, though, was the ISRO’s 725.5-kilogram (1,599-pound) Cartosat-2 - a satellite used for earth observation much like NASA’s Landsat program.

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.

Thousands of scientists in Germany, Peru and Taiwan are preparing for a new year without online access to journals from the Dutch publishing giant Elsevier. Contract negotiations in both Germany and Taiwan broke down in December, while Peru’s government has cut off funding for a licence.
“It’s very unpleasant,” says Horst Hippler, spokesperson for the DEAL consortium of state-funded universities and research organizations, which is overseeing negotiations in Germany. “But we just cannot accept what Elsevier has proposed so far.”
