Una investigación ha encontrado que la mayor parte de la lechuga francesa contiene trazas de productos químicos que interrumpen la función hormonal, algunos de los cuales están prohibidos, informa el diario l'Environnement.

Many tropical Pacific island nations are struggling to adapt to gradual sea level rise stemming from warming oceans and melting ice caps. Now they may also see much more frequent extreme interannual sea level swings. The culprit is a projected behavioral change of the El Niño phenomenon and its characteristic Pacific wind response, according to recent computer modeling experiments and tide-gauge analysis by scientists Matthew Widlansky and Axel Timmermann at the International Pacific Research Center, University of HawaiÊ»i at Mānoa, and their colleague Wenju Cai at Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Australia.

During El Niño, warm water and high sea levels shift eastward, leaving in their wake low sea levels in the western Pacific. Scientists have already shown that this east-west seesaw is often followed six months to a year later by a similar north-south sea level seesaw with water levels dropping by up to one foot (30 cm) in the Southern Hemisphere. Such sea level drops expose shallow marine ecosystems in South Pacific Islands, causing massive coral die-offs with a foul smelling tide called taimasa (pronounced [kai’ ma’sa]) by Samoans.

A start-up business focused on finding new ways of using insect protein in food products is a finalist in this year’s MassChallenge, the Boston-based start-up competition and world’s largest accelerator program. Get over your squeamishness, because bug-based foods will soon infest our markets.

The “elevator pitch” for Israel-based The Flying Spark states their intent to manufacture protein powder based on insect larvae that can be added to a wide range of food products, replacing today’s protein powders – commonly made from whey, soy, or casein. Insects contain extremely high protein, fiber, micro-nutrients and mineral content. They’re also naturally low in fat, and cholesterol-free. The tipping point for this product’s potential is that insect protein will cost less to produce than any other source of animal protein.

Horses need help when it comes to insect pests like flies. But, unfortunately, horse owners are in the dark about how best to manage flies because research just hasn't been done, according to a new overview of equine fly management in the latest issue of the Journal of Integrated Pest Management, an open-access journal that is written for farmers, ranchers, and extension professionals.

Casi el 47 por ciento de los mariscos comestibles proveídos en los Estados Unidos se pierde cada año, principalmente por los consumidores, sugiere una nueva investigación del Centro Johns Hopkins para un futuro habitable (CLF por sus siglas en inglés).

Los hallazgos, publicados en la edición de noviembre de Cambio Ambiental Global, vienen como residuos de alimentos en general, ha estado en el centro de atención y ha generado preocupación acerca de la sostenibilidad de los recursos pesqueros del mundo. En los EE.UU. y en todo el mundo, a la gente se les aconseja comer más mariscos, pero la sobrepesca, el cambio climático, la contaminación, la destrucción del hábitat y el uso de peces para otros fines además de la alimentación humana amenazan el suministro mundial de pescado.
