Large-scale US wind power would cause warming that would take roughly a century to offset

Extracting energy from the wind causes climatic impacts that are small compared to current projections of 21st century warming, but large compared to the effect of reducing US electricity emissions to zero with solar. Researchers report the most accurate modelling yet of how increasing wind power would affect climate, finding that large-scale wind power generation would warm the Continental United States 0.24 degrees Celsius because wind turbines redistribute heat in the atmosphere.

The cart before the horse: A new model of cause and effect

Natural little scientists, human babies love letting go of things and watching them fall. Baby’s first experiment teaches them about more than the force of gravity. It establishes the concept of causality – the relationship between cause and effect that all human knowledge depends on. Let it go, it falls. The cause must precede its effect in time, as scientist from Galileo in the 16th Century to Clive Granger in 1969 defined causality.

New cause of brain bleeds identified

Neurologists have provided, for the first time, evidence that blood deposits in the brain may not require a blood vessel tear. The researchers found that brain endothelial cells, the cells that line blood vessels of the brain, have the capacity for engulfing red blood cells and depositing them outside the blood vessels and into the substance of the brain, without requiring a disruption of the vasculature.

Can a common heart condition cause sudden death?

About one person out of 500 has a heart condition known as hypertrophic cardiomyopathy (HCM). This condition causes thickening of the heart muscle and results in defects in the heart’s electrical system. Under conditions of environmental stress such as exercise, HCM can result in sudden death. In other cases, patients may go undiagnosed, with their heart function declining gradually over decades.
