Phys.org / 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.

Medical Xpress / REM and deep sleep, not just total sleep time, associated with disease risk

Greater amounts of REM and deep sleep were associated with lower risks of dozens of diseases, and less than 5 hours of total sleep was associated with high disease risks, according to a new study published Sept. 17 in the ...

Phys.org / Decoding the DNA switches behind gene regulation

Understanding gene regulation may be key to interpreting human disease genetics. Genes are regulated in part by stretches of DNA called enhancers, which define when, where and how strongly each gene is turned on. Mapping ...
