WISE study starts in Toulouse: 60 days of bed-rest for terrestrial female astronauts

21.03.2005


Since Saturday, 19 March, the study entitled Women International Space Simulation for Exploration (WISE) has been fully under way. All participants in the first of two campaigns have been lying in bed, tilted head down at an angle of 6º below horizontal, so that their heads are slightly lower than their feet.

This position results in physiological changes that also occur in astronauts during space flight. The study will assess the roles of nutrition and combined physical exercise in countering the adverse effects of prolonged gravitational unloading by bed-rest.

The first volunteers arrived at the MEDES Space Clinic in Toulouse on 22 February for the start of the collection of physiological data, which will serve as the baseline data throughout the whole study. This preliminary period lasted 20 days, after which the first two volunteers went to bed; the last two, who arrived on 27 February, did so on 19 March.



More than 1600 women responded to the ESA call for candidates, which closed in January. As planned, twelve women were selected for this first campaign. They come from France, Great Britain, Germany, Finland, The Netherlands, Poland, and the Czech Republic, so that the WISE study also attracted great interest in the new member countries of the European Union.

This study is a joint venture between the European Space Agency (ESA), the French space agency (CNES), the National Aeronautics and Space Administration (NASA) and the Canadian Space Agency (CSA). It is being carried out by MEDES, the French Institute for Space Medicine and Physiology, in the clinical research facility at the Rangueil hospital in Toulouse, France.

WISE needs 24 female volunteers altogether, who will remain in bed for a total duration of 60 days. The test subjects will be divided into three groups of eight. One will be the control group, receiving no extra stimulus over the course of the bed-rest period. The second group will undertake an exercise programme whilst in bed. The third will receive a nutritional supplement throughout the 60 days.

For the 20 days prior to the bed rest period, the test subjects will take part in the collection of baseline data. During the 20 days following the bed-rest period they will undergo similar tests for comparison with the baseline data. The WISE study is being conducted in two campaigns, with 12 volunteers in each. The second campaign starts in September. Volunteers can still apply.

The data collected by WISE will be used to draw conclusions about such aspects as muscle condition, blood parameters, cardiovascular condition, coordination of movements, changes in immune system, bone formation and psychological wellbeing. External experts reviewed all scientific protocols of the study prior to selection, and the responsible French ethical committee in Toulouse has approved the integrated study design of WISE.

With the European Space Agency’s future plans for human space exploration, the results expected from WISE will prove valuable in planning long-duration human missions. This research will also have clinical significance on Earth, advancing knowledge and pointing to improved methods of assisting recovery by bedridden patients. Studying the early effects of reduced activity on a molecular level is expected to provide further evidence of the benefits of regular exercise in the prevention of conditions like type 2 diabetes and high blood pressure.

Im Focus: Data storage using individual molecules

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.

Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...

Im Focus: Data use draining your battery? Tiny device to speed up memory while also saving power

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

Im Focus: An energy-efficient way to stay warm: Sew high-tech heating patches to your clothes

Personal patches could reduce energy waste in buildings, Rutgers-led study says

What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
