Less sickness with more motion and/or mental distraction

Less sickness with more motion and/or mental distraction.

BACKGROUND Motion sickness may reduce passenger comfort and crew performance. Countermeasures are dominated by medication with specific and often undesirable side effects. OBJECTIVE To shown that sickness due to motion can be reduced by adding an inherent non-sickening vibration and by mental distraction. METHODS Eighteen blindfolded subjects were exposed to 20 minutes of off-vertical axis ...

More with less Xist.

S ince the birth of Dolly, the first mammal produced from somatic cell nuclear transfer (SCNT), little progress has been made in the efficiency of cloning. Overall, about 0.5–2% of the embryos reconstructed by SCNT develop to term after transfer of reconstructed embryos to recipient females. In PNAS, Matoba et al. (1) report significant improvement in cloning efficiency by manipulation of the l...

Learning More, with Less

P racticing chemists solve problems via “chemical intuition”, a quality that lets them skip intermediate details and get to the essential result, even if the outcome is counterintuitive to the uninitiated. There is no human shortcut to building this intuition; chemists hone their skills through years of experience of learning and memorizing patterns of molecular structure and reactivity. It is ...

Unusual presentation of motion sickness: Case report

Introduction: Motion sickness is a normal response to real. Perceived or anticipated movement. Although the prognosis is excellent it may be incapacitating for people with an occupation that requires constant movement, such as a flight attendant, pilot, astronaut, or ship crew members. The symptoms progresses from initial dizziness to vomiting. Fortunaterly most symptoms disappear once the stim...
