Use of behavioural stochastic resonance by paddle fish for feeding

Article Abstract:

Stochastic resonance boosts the normal feeding behaviour of paddlefish, Polyodon spathula, which use passive electro-receptors to detect electrical signals from planktonic prey. It was possible to identify two bands of noise-enhanced strike probability, one above the rostrum and another larger band below the rostrum, around the mouth. This banding pattern reflects the boosting of vertical strike distances. It seems that stochastic resonance increases the sensitivity of peripheral electroreceptors, or acts within the brain, or both.

Unbalanced US budgets

Article Abstract:

The Balanced Budget Amendment, which failed to pass through the United States Senate, reveals the negative attitude of politicians toward scientific research. The Amendment was proposed by the Republican Party to reduce the budget deficit by cutting funds allotted to scientific research. The Amendment failed to pass through the Senate as it was deemed to have flawed guidelines.

Balancing the unbalanced

Article Abstract:

The causes for elderly but healthy people that face serious injuries in falls are investigated. Exploiting the phenomenon of stochastic resonance, biological physicists have designed vibratory sole that helps to maintain balance during fall.
