La Agencia de Protección Ambiental de Estados Unidos (FDA) y la Administración de Alimentos y Narcóticos (FDA) emitieron hoy el proyecto de asesoramiento actualizado sobre el consumo de pescado. Las dos agencias han concluido que las mujeres embarazadas y lactantes, aquellas que podrÃan quedar embarazadas y los niños pequeños deben comer más pescado que sea bajo en mercurio a fin de obtener importantes beneficios de salud y de desarrollo. El proyecto de asesoramiento actualizado se ajusta a las recomendaciones de las GuÃas Alimentarias para los Estadounidenses 2010.

Not all non-human animal dads are cut out for family life, but there are a number of species who have become known for their role as fathers who deserve a salute, from giant water bugs who carry dozens of eggs on their backs to males who actually get pregnant and dads who operate solo as single parents. This Father's Day, it's time to celebrate some of the amazing dads from the animal kingdom who go above and beyond when it comes raising and protecting their young.
Red Fox
Male red foxes aren't just loving mates, but excited and protective fathers. They take on the task of providing food for their mates every few hours for about a month after she gives birth. Then they take on the role of teacher – but teachers who like to take time out to play. Even when it’s time to get serious and teach their young how to start finding their own food, fox dads help them out and make sure they don't really go hungry by hiding it near their dens.

You could say that, at least until now, cars and tomatoes have basically nothing in common. Tomatoes go from green to red as they ripen, and cars, well, they seem to be getting greener.

Indeed, as cars continue to reduce vehicle weight in order to improve fuel economy, the use of plastics is becoming ever more common.

Tomorrow is Father's day and animals are not normally thought of as being good fathers. For most species, the mothers do most of the work feeding and nurturing their young. Owl monkeys appear to be an exception!
If there were a competition for "best father" in the animal kingdom, owl monkeys might very well win.
Why? Because father owl monkeys provide most of the care needed by their young--carrying them almost all the time, even when chased by predators. By contrast, caregiving from owl monkey mothers to their young is limited almost exclusively to nursing.
Considering the high prevalence of "deadbeat dads" and even "cannibal dads" in the animal kingdom, why--of all creatures--are father owl monkeys so attentive and protective of their young? This question is answered by Patricia C. Wright of Stony Brook University in the accompanying video.

A new study by researchers at the University of Bristol and Plymouth Marine Laboratory has shed light on how different species of marine organisms are reacting to ocean acidification.
Since the Industrial Revolution, nearly 30 per cent of all the carbon dioxide produced by manmade emissions has been absorbed by the ocean, causing a drop in pH of ocean surface waters: ocean acidification.
