Understanding the continuous corn yield penalty

A six-year University of Illinois study found that continuous corn systems experience a yield reduction compared to corn rotated with soybean, known as the continuous corn yield penalty. The study identified N availability, corn stover accumulation, and unfavorable weather as primary causes of the penalty.

'Evolutionary glitch' possible cause of childhood ear infections

Scientists at King's College London found that the middle ear cavity is formed by two different tissue types, one of which is less efficient at clearing debris and more susceptible to infection. This 'evolutionary glitch' may be the reason why some children are more prone to developing chronic ear problems like glue ear.
