Yesterday, 12 adults in Cologne, Germany climbed into special beds where they will remain for 60 days to help scientists better understand the impact of longterm space flights on the human body.
The Artificial Gravity Bed Rest Study
is a joint program from European Space Agency (ESA) and NASA. From the ESA:
...They will be kept in beds with the head end tilted 6° below horizontal and must ensure one of their shoulders is touching the mattress at all times.
As blood flows to their heads and muscle is lost from underuse, researchers will investigate changes and test techniques from diet to physical exercise. Artificial gravity is one of the techniques under the spotlight this time around and will see some of the participants sent spinning...
A number of different experiments will be carried out over the course of the study, looking at cardiovascular function, balance and muscle strength, metabolism and cognitive performance among other factors...
“To make these missions possible, various risks to astronaut health must be minimised," (says ESA team leader for research Jennifer Ngo-Anh). "This study allows us to address the issue of muscular atrophy caused by weightlessness, but also other stressors such as cosmic radiation, isolation and spatial restrictions.”
For years a friend has been telling my diet was hurting my general demeanor.
A favorite kitchen chemistry (and physics) experiment of kids (and adults), Ooblek is the weird result of mixing cornstarch with water. Now, MIT engineers have developed a mathematical model that can predict and simulate how the non-Newtonian fluid switches between liquid and solid depending on the pressure applied to it. From MIT News: Aside from […]

Stanley Whittingham and Dr. John Goodenough (Charles Dharapak / Yoshiaki Sakamoto / Kyodo News / Binghamton University) The 2019 Nobel Prize in Chemistry has been awarded to three scientists whose work developing lithium-ion batteries made mobile phones, iPads, laptops, and electric cars possible. The three recipients are U.S. engineer […]
There’s overwhelming support for clean energy, and the planet is giving us more reasons to invest in renewable power sources with every passing year. Even in the most inhospitable areas, wind and solar can provide a good chunk of our power, if not all of it. So why aren’t we all taking advantage of it? […]
Hey, we love Netflix and Hulu, but let’s face it: The whole setup doesn’t exactly encourage active viewing. For all the binge-watching we’ve done, it’s tough to expand our horizons or learn anything new – except for how many episodes of “The Office” it takes to make us fall asleep. It was only a matter […]
