A University of California, Riverside, study that sought to determine barriers to health care among Spanish-speaking Latino farmworkers in rural communities has devised an innovative health care service delivery model that addresses many challenges these communities face: mobile health clinics that bring health care services to patients in their community spaces.
Motile sperm are difficult to collect with a conventional cell sorter because they are vulnerable to physical damage. A Japanese research collaboration has developed a technique using a cell sorter with microfluidic chip technology to reduce cell damage and improve in vitro fertilization rates. This research is expected to increase in vitro fertilization rates to improve production of experimental animals and livestock, and could be used as a fertility treatment in reproductive medicine.
Worldwide there is growing demand for animal products for human nutrition, despite the popularity of plant-based diets. This means more feed is needed for animals. Future feedstuffs will need to be produced without exacerbating deforestation. Insects and microalgae are up-and-coming sectors to meet protein demands for humans and animals. Therefore, researchers at Göttingen University investigated whether these alternative protein sources alter meat quality. Results appeared in the Journal of the Science of Food and Agriculture (JSFA).
Artificial light at night attracts insects, thus giving invasive cane toads in places like Australia a lot more food to eat, researchers have found, potentially giving a boost to such invasions.
Precision agriculture technologies can improve efficiency on smaller farms
Winter squash is an important crop grown in the Willamette Valley, and the most important processing cultivar, Golden Delicious, has been grown in Oregon since the 1970s. Over the last two decades, however, growers have noticed yield declines throughout the valley. Agriculture specialists have identified an association between yield decline and disease symptoms such as stunting, vascular discoloration, late-season vine collapse, and root and crown rot, all symptoms of soilborne disease.
Scientists from ORNL and a dozen other international research institutions ran a series of simulations to produce the most elaborate set of projections to date that illustrates possible changes in nine monsoon regions across five continents.
Scientists have found a way to control different plant processes -- such as when they grow -- using nothing but coloured light. The development reveals how coloured light can be used to control biological processes in plants by switching different genes on and off. The researchers hope that their findings could lead to advances in how plants grow, flower, and adapt to their environment, ultimately allowing increases in crop yields.
NIMS and AIST have developed a small sensor capable of continuously monitoring the plant hormone ethylene. Ethylene gas promotes ripening in fruits and vegetables, but excessive exposure promotes them to rot. The new small sensor can be used to monitor fruits and vegetables by continuously detecting ethylene gas, ensuring the freshness during transportation and storage, and helping reduce food waste.
Brazil is one of the top three producers of both soy and corn globally, and its agricultural sector accounts for one-fifth of the country's economy. Deforestation and land-clearing practices have long been linked to decreases in biodiversity, and increases in temperature, stream flow, fire occurence, and carbon dioxide emissions. According to a Dartmouth study published in Nature Sustainability, these land-clearing practices in Brazil are also altering the climate and can significantly reduce corn yields
