In India, swapping crops could save water and improve nutrition

Wed, 04/07/2018 - 20:18
India will need to feed approximately 394 million more people by 2050. Meanwhile, many of its regions are chronically water-stressed, and nutrient deficiencies are widespread -- 30 percent of Indians or more are anemic. But a new study shares a brighter outlook: replacing some rice with less thirsty crops could dramatically reduce water demand in India, while also improving nutrition.

A diet rich in nuts improves sperm count and motility

Wed, 04/07/2018 - 16:20
The inclusion of nuts in a regular diet significantly improves the quality and function of human sperm, according to results of a randomized trial which measured conventional semen parameters and molecular changes over a 14-week study period. The findings, say the investigators, 'support a beneficial role for chronic nut consumption in sperm quality' and reflect a research need for further male-specific dietary recommendations.

New genomic regions associated to weight gain in Nelore cattle

Tue, 03/07/2018 - 16:28
A pioneering research project has identified genes potentially associated with functions such as growth and weight gain in the Nelore breed. These functions are key to beef production. The researchers pinpointed genomic regions that had changed owing to selection, referring to these as genomic signatures of selection.

Host plants tell insects when to grow longer wings and migrate

Mon, 02/07/2018 - 20:47
Scientists have discovered that the quality of the host rice plant determines whether the brown planthopper, a major pest on rice in Asia, grows short wings or long wings.

A new twist on how parasites invade host cells

Mon, 02/07/2018 - 16:11
Researchers have decoded the mechanisms used by the parasite Toxoplasma gondii to enter the cells of a host. Using high-resolution, high-speed imaging, they identified a unique process by which the parasite closes the 'entry door' it creates in order to enter and inhabit a host cell.

Mandatory labels reduce GMO food fears

Wed, 27/06/2018 - 21:05
As national regulators work to develop labeling standards for foods containing genetically modified ingredients, a researcher finds that consumer opposition to GMOs dropped significantly after Vermont adopted mandatory labels.

Dramatic change in way ancient diets are calculated

Wed, 27/06/2018 - 21:03
Knowing what extinct animals ate has long been determined by analyzing carbon isotopes locked inside fossil teeth. For two decades, a key isotope value in these equations has been assumed to be the same for all plant-eating mammals, but new research contradicts that assumption, revealing that the value changes with body size.
