During long Midwest winters, deer can wreak havoc on hay and other stored livestock feed. However, planting fall cover crops, such as clover, turnips and peas, may help wildlife managers provide deer with a nutrient-rich alternative that can lure them away from livestock feed. Researchers are conducting a controlled experiment to identify which cover crops deer prefer.

Distillers dried grains with solubles, a co-product of the ethanol industry, is becoming a more common ingredient in swine diets. However, distillers dried grains with solubles can be high in sulfur, and data are limited on the amount of sulfur that pigs can tolerate in the diet. Therefore, researchers have conducted research to investigate effects of high levels of sulfur in diets for pigs.

Climate change is likely to leave a lot of lemurs looking for new places to live on their island home of Madagascar. A new study predicts where lemurs are likely to seek refuge as temperatures rise between now and 2080. The researchers identified three areas on the island that will be particularly important for lemurs in the future, as well as key corridors that will allow lemurs to reach these areas from their current spots.

Scientists have discovered that maternal diet affects the nutrient composition of fluid in the womb of women and thus may aid in the development of nutritional interventions to support the very earliest stages of pregnancy.

Researchers used algae as a mini-factory to produce a malaria parasite protein. The algae-produced protein, paired with an immune-boosting cocktail suitable for use in humans, generated antibodies in mice that nearly eliminated mosquito infection by the malaria parasite. The method is the newest attempt to develop a vaccine that prevents transmission of the malaria parasite from host to mosquito.

Facing the need of a company that sells mango as raw material for processing as puree, nectar or juice, researchers designed a prototype pasteurization machine for the product and a procedures manual to keep it in excellent condition after harvest.

The appearance of malaria parasites resistant to medicines is one of the main obstacles in combating the disease. In order to slow down this phenomenon, it is essential to avoid exposing the pathogen to the same molecules. For this reason, researchers are testing new treatments. They have recently demonstrated the efficacy of a "bi-therapy", which combines artesunate (a derivative of artemisinin, recommended by the WHO) with Malarone® (or Malanil®). The latter has been administered up to now as a preventative treatment for travelers or as a treatment in the industrialized nations, because it is so expensive. The fact that its patent entered the public domain in 2013 has made it possible to envisage its use among populations living in regions where the disease is endemic.

New research explores why caring for young is shared unequally between the sexes in so many animal species. Parental care involves one of the fundamental conflicts of interest between the sexes. Care by either partner is beneficial to both partners as it increases the health and survival prospects of the common young; providing care is costly only to the caring individual. As a result, each partner does best in a situation where most of the care is provided by the other partner--an outcome that is clearly impossible.
