Grass and clover can provide more than animal feed

Growing leys—grass and clover—is nothing new in Swedish agriculture. But in the arable farming regions dominated by cereal production, leys are less common. One reason is that there needs to be a market for what is harvested.

Textbooks may have misdrawn this basic brain structure for 100 years

Scientists discovered that brain-cell axons may not be smooth tubes as textbooks have shown for more than a century, but instead naturally resemble strings of tiny pearls. Those pearl-like structures can change with neural activity and may help control how quickly electrical…
