Al final de un largo año, a veces ayuda a reconectarse con aquello que motiva tu trabajo.
Para Karin Albornoz, estudiante de doctorado quien trabaja en biología molecular relacionada al daño que sufren, por frío, los tomates después de la cosecha, en el laboratorio Diane Beckles de UC Davis, esto significa salir al mundo a trabajar directamente con pequeños granjeros.
"Paso tanto tiempo en el laboratorio", dijo Albornoz. "Algunas veces paso todo el día en el laboratorio extrayendo ARN o escribiendo un reporte. Esto me recuerda la razón por la que...

With the ultimate goal of getting people to eat more," co-project leader Beth Mitcham told an ABC-affiliated reporter. Mitcham is a UC Davis Cooperative Extension post harvest pomologist.

Downy mildew of lettuce, caused by Bremia lactucae, is the very common foliar disease that results in the familiar yellow to brown leaf lesions and accompanying white sporulation on the lesions. However, the systemic phase of lettuce downy mildew may be less familiar to growers and pest control advisors. In the spring of 2009, systemic downy mildew was very common in coastal California. Currently in 2010, systemic downy mildew is not as serious but is still being observed in some coastal plantings.
Symptoms of systemic downy mildew may be seen on both lettuce leaves and the central, internal core of the lettuce plant. For leaf symptoms, examine the plant for large, elongated regions of the leaf that are discolored...

The rainy and cold spring weather in 2010 is apparently having an effect on head lettuce quality in Salinas Valley fields. Symptoms appear as very small, brown flecks and spots along the margins of young leaves (photo 1). Affected leaves are usually found deep within the head. It appears that these defects are occurring in multiple iceberg cultivars in various parts of the valley. Clearly this is a physiological disorder and superficially looks similar to russet spot; however, most of the flecks do not occur on the leaf midribs (photo 2) as would be typical for russet spot. Russet spot is caused by ethylene production and can occur in mature to over mature lettuce, especially following anaerobic conditions in...

When Newsday's Erica Marcus had a burning question about ripening fruit, she turned to UC Davis post harvest experts. Marcus writes a weekly column for the magazine's Web site that answers "burning questions" about food.
In the past, she's helped readers who want to avoid soggy stirfry, identify whole grains, and know exactly when to cover or uncover a pot cooking on the stove. This week, she answered for readers: "Which fruits ripen after they are picked - and why?"
"For the lowdown on ripening," she wrote, "I called the postharvest information...
