very nice paper on adaptation of cells to microgravity

Normally we associate levitation of objects to superconducting materials. Here a new technique is shown where levitation of a whole new range of materials is shown. "The large temperature gradient leads to a force that balances gravity and results in stable levitation," said Fung, the study's lead author. "We managed to quantify the thermophoretic force and found reasonable agreement with what is predicted by theory. This will allow us to explore the possibilities of levitating different types of objects." Paper at http://aip.scitation.org/doi/10.1063/1.4974489 New microgravity experiments possibility?

not really I fear .... "Typical sizes of the trapped particles are between 10 μm and 1 mm at a pressure between 1 and 10 Torr. The trapping stability is provided radially by the increasing temperature field and vertically by the transition from the free molecule to hydrodynamic behavior of thermophoresis as the particles ascend."

Might still be OK micro to mm sized experiments. The technique seems to be reliable and cheap enough to compete with other types of microgravity approaches - more research needed to define boundaries of course.

Loss of connectivity in the multisensory integration cortical areas after short term microgravity experience, which could explain astronauts decrease of performance in sensorimotor tasks and spatial working memory. However, the effect should wear off after a few days in microgravity and after adaptation to incongruent vestibular information. ISS experiment needed...

38 degree core body temp in microgravity stabilised after 2 months - due to reduced conv. heat transfer+evaporation https://www.nature.com/articles/s41598-017-15560-w

so that's hypopyrexia (augmented concentrations of interleukin-1 receptor antagonist) AND hypothermia (convection/evaportation)? what puzzles me is that temperatures take so long to return to baseline after astronauts return to earth.

A good DIY project - build a tractor beam using 3D printed parts. The 3D files and research are available for download. A new way for microgravity research @fichbio ?

Drones for microgravity.

Docking Impender assumed a demonstrator of a novel kinetic energy absorber applied to CubeSat mockups tested on a 2D microgravity simulator: an air bearing table. Inspired by prof. Lagiewka: http://www.euroinfrastructure.eu/en/safety/byl-zderzak-lagiewki-bedzie-bariera-lagiewki/

The new findings come from a recent NASA study in which 12 astronauts aboard the ISS took ultrasound images of their hearts before, during, and after their six-month stint in space. What they found confirmed scientists' previous prediction: In microgravity, the human heart becomes more spherical by a factor of nearly 10 percent.

nice research - almost like a follow-up to our BMI work some time ago

Photo credit: The glass has a number of interesting innovations. Ballentine's. A liquor company has created a " Space Glass" that they say can work in the microgravity environment of space. The Open Space Agency's James Parr was commissioned to create the product, and the results are actually quite interesting.

Makes sense specially after seeing very good japanese whiskey arriving at the ISS :-) http://phys.org/news/2015-08-japanese-whisky-international-space-station.html

This review provides an overview of the progress in using the low-gravity environment of space to explore critical phenomena and test modern theoretical predictions.

Why do we sleep? One answer could be: to clear waste products accumulated during the day. To prevent aging and neurodegeneration, the body must maintain homeostasis. What would happen if we experience chronic sleep loss? What would happen if microgravity impairs the cerebrospinal fluid to flush the brain? What would happen if cosmic radiations increase the amount of daily waste products?

OHB and Luxspace venture to ensure human life on the Moon! Research on O2 production and others.....

Has BH at least completed an orbit yet? Or are they still at 10mins in microgravity?

beautiful research
