Five years after the Deepwater Horizon rig exploded, sending oil into the Gulf of Mexico for 87 days, wildlife are still struggling. The Gulf, with its deep waters, sandy beaches, lush wetlands and coral reefs, is a vast system that supports more than 15,000 species of wildlife – fish, birds, marine mammals and many, many others.

A new report from the National Wildlife Federation looks at how 20 types of wildlife that depend on a healthy Gulf are faring in the wake of the BP oil spill. The full extent of the spill’s impacts may take years or even decades to unfold, but Five Years & Counting: Gulf Wildlife in the Aftermath of the Deepwater Horizon Disaster examines what the science tells us so far.

Losing plant species is directly linked to long-term declines in the stable productivity of grasslands, a new study has shown. The study demonstrates for the first time that for every decrease in plant biodiversity there is a proportional decrease in the stable production of plant biomass through time of grassland ecosystems. Over the long-term, factors such as rising levels of carbon dioxide, nitrogen, more frequent grazing, or drought, only affect ecosystem stability in as much as they affect biodiversity.

La capacidad de todos los niños de tener éxito en la escuela se ve influida por muchos factores externos: la calidad del profesorado, la paternidad, la pobreza, la geografía, por nombrar algunos. Pero muy poca atención se ha prestado a la influencia de las paredes de las habitaciones  de un niño o, más bien, a la pintura que está en ellas y al plomo que puede estar en esa pintura.

Un nuevo estudio publicado en el Harvard Educational Review sugiere que los esfuerzos para reducir la exposición al plomo de los niños han conducido a logros académicos tangibles en Massachusetts.

La investigadora Jessica Wolpaw Reyes, profesora asociada de economía en la Universidad de Amherst, ha estado estudiando los efectos de la exposición al plomo desde la década de 1990. El metal despertó su interés cuando era un estudiante de posgrado en Harvard, cuando estaba embarazada de su primer hijo y viviendo en una vieja casa rica en plomo.

Marking a precedent-setting conservation partnership, Apple and the Conservation Fund will purchase two large areas of working forest, the organizations announced on Thursday. The move is expected to conserve “more than 36,000 acres of working forestland in Maine and North Carolina, ensuring these forests stay forests and any timber on the land is harvested sustainably,” the partners said in a joint announcement.

This initial purchase of U.S. working forestland marks “the beginning of a worldwide effort, one that represents a new approach as it reassesses its impact on the world’s paper supply chain,” Lisa P. Jackson, Apple’s vice president of environmental initiatives, and Larry Selzer, president and CEO of the Conservation Fund, wrote in a Medium op-ed. Prior to joining Apple, Jackson led the U.S. EPA as President Barack Obama’s EPA Administrator from 2009 to 2013.

 Investigadores de la Universidad de Wisconsin-Madison han anunciado un importante paso adelante en el desarrollo de materiales que pueden repeler hidrocarburos, un descubrimiento que podría conducir a nuevas capas protectoras y mejores enfoques para la limpieza de derrames de petróleo.

En un nuevo artículo en la revista Advanced Functional Materials, el profesor de ingeniería química y biológica David Lynn y su asistente científico Uttam Maná, describen nuevos recubrimientos que son extremadamente repelentes a los aceites (o "superoleofóbicos") en ambientes marinos.

Lynn y Maná inicialmente no se propusieron desarrollar materiales altamente repelentes del aceite, pero su trabajo en afinar la estructura de materiales a escala nano y micro, condujo al hallazgo inesperado.

A key question in the climate debate is how the occurrence and distribution of species is affected by climate change. But without information about natural variation in species abundance it is hard to answer. In a major study, published today in the leading scientific journal Current Biology, researchers can now for the first time give us a detailed picture of natural variation.
