Exposure to hypomagnetic field space for multiple generations causes amnesia in Drosophila melanogaster.
This is the introduction of Drosophila into the study of learning and memory affected by removal of the geomagnetic field (GMF) for successive generations. Using the operant visual learning/memory paradigm at a flight simulator, the present study revealed that wild-type flies raised in a hypomagnetic field environment continuously for 10 successive generations were gradually impaired in visual ...
متن کاملA Hypomagnetic Field Aggravates Bone Loss Induced by Hindlimb Unloading in Rat Femurs
A hypomagnetic field is an extremely weak magnetic field--it is considerably weaker than the geomagnetic field. In deep-space exploration missions, such as those involving extended stays on the moon and interplanetary travel, astronauts will experience abnormal space environments involving hypomagnetic fields and microgravity. It is known that microgravity in space causes bone loss, which resul...
متن کاملEnvironmental health in space.
physical limitations of Earth to include the outer reaches of space. Over the past 40 years, beginning with the former Soviet astronaut Yuri Gagarin, we have been exploring this previously unknown and inaccessible realm. Although the number of people who have so far experienced the environment of space is limited (some 300 astronauts), the lay public is expected to join the ranks of these wellt...
متن کاملIs Earnings Nonresponse Ignorable?
Is Earnings Nonresponse Ignorable? Earnings nonresponse in the Current Population Survey is roughly 30% in the monthly surveys and 20% in the annual March survey. Even if nonresponse is random, severe bias attaches to wage equation coefficient estimates on attributes not matched in the earnings imputation hot deck. If nonresponse is ignorable, unbiased estimates can be achieved by omitting impu...
متن کاملIgnorable Information in Multi-Agent Scenarios
In some multi-agent scenarios, identifying observations that an agent can safely ignore reduces exponentially the size of the agent’s strategy space and hence the time required to find a Nash equilibrium. We consider games represented using the multi-agent influence diagram (MAID) framework of (Koller and Milch 2001), and analyze the extent to which information edges can be eliminated. We defin...
