A new tool can predict the odds that honey bee colonies overwintered in cold storage will be large enough to rent for almond pollination in February. Identifying which colonies will not be worth spending dollars to overwinter can improve beekeepers' bottom line.
Read moreResearch by ecologists shows strong evidence in a freshwater lake of 'fishing down the food web' – the deliberate shift away from top predatory fish on the food chain to smaller species closer to the base. While the effect has historically been observed almost exclusively in marine ecosystems and ocean fisheries, there has been little evidence of the effect in freshwater ecosystems.
Read moreA new study hat accounts for folic acid fortification in staple foods made from wheat and corn, such as bakery bread and tortillas, found that large proportion of women of childbearing age have FA intake below levels recommended by the World Health Organization, potentially raising the risk for neural tube defects in their offspring. The study is one of a few to investigate FA intake after fortification.
Read moreA new study suggests that people might want to avoid making any important decisions about the future on an empty stomach.
Read moreAchieving an adequate, healthy diet in most low- and middle-income countries will require a substantial increase in greenhouse gas emissions and water use due to food production, according to new research.
Read moreEarly rice growers unwittingly gave barnyard grass a big hand, helping to give root to a rice imitator that is now considered one of the world's worst agricultural weeds.
Read moreA new statistical modelling tool will enable land management authorities to predict where invasive weed species are most likely to grow so they can find and eliminate plants before they have time to spread widely.
Read moreWhen Hennig Brandt discovered the element phosphorus in 1669, it was a mistake. He was really looking for gold. But his mistake was a very important scientific discovery. What Brandt couldn't have realized was the importance of phosphorus to the future of farming.
Read moreA group of forager-farmers in Bolivia's tropical forests — known for having remarkable cardiovascular health and low blood pressure — experienced changes in body mass and diet over a nine-year period, with increased use of cooking oil being the most notable dietary change.
