A group of scientists, led by a team from the University of Bristol, has observed a sudden increase of ice loss in a previously stable region of Antarctica. The research is published today in Science.
Can Ice Loss Affect Gravity?

Fine Particulate Air Pollution Linked to Increased Risk of Childhood Autism
Exposure to fine particulate air pollution during pregnancy through the first two years of a child’s life may be associated with an increased risk of the child developing autism spectrum disorder (ASD), a condition that affects one in 68 children, according to a University of Pittsburgh Graduate School of Public Health investigation of children in southwestern Pennsylvania. The research is funded by The Heinz Endowments and published in the July edition of Environmental Research.
National-scale effort addresses pollinator declines
A new White House plan to promote the health of bees and other pollinators calls for boosting research into ongoing population declines—and potential solutions. The plan, released yesterday, also recommends numerous measures to address growing concerns about the threat that bees, birds, butterflies, and other pollinators face from multiple factors, including pathogens, pesticides, climate change, and habitat loss. By addressing scientific knowledge gaps, the research should make the plan’s suggested measures much more effective, the report says.
A la alza la exposición al calor extremo en EEUU
La exposición de los residentes estadounidenses al calor extremo podría aumentar de cuatro a seis veces a mediados de siglo, tanto por el calentamiento global como por una población que está creciendo especialmente rápido en las regiones más calientes del país, según una nueva investigación.
El estudio, realizado por investigadores del Centro Nacional de Investigación Atmosférica (NCAR) y la Universidad de la Ciudad de Nueva York (CUNY), pone de relieve la importancia de considerar los cambios sociales cuando se trata de determinar los futuros impactos climáticos.
El agujero de la capa de ozono se está reduciendo
Nuevos datos de satélites de la NASA confirman lo que otras investigaciones han demostrado, a saber, que el agujero en la capa de ozono parece estar cada vez más pequeño.
El ozono es crucial para nosotros aquí en la Tierra, ya que nos protege de algunas de las radiaciones más perjudiciales del sol. En la década de 1980 se confirmó que una gran cantidad de productos químicos como los Cloro Fluoro Carbonos (CFCs) que habíamos estado utilizando en la industria y en particular en los aerosoles, había estado consumiendo la capa de ozono, creando varios agujeros, incluyendo una preocupante gran agujero sobre el Ártico. A largo plazo el uso de CFCs amenazó con destruir este escudo vital completamente si no actuamos.
What are the bright spots on dwarf planet Ceres?
NASA's Dawn mission captured a sequence of images, taken for navigation purposes, of dwarf planet Ceres on May 16, 2015. The image showcases the group of the brightest spots on Ceres, which continue to mystify scientists. It was taken from a distance of 4,500 miles (7,200 kilometers) and has a resolution of 2,250 feet (700 meters) per pixel.
"Dawn scientists can now conclude that the intense brightness of these spots is due to the reflection of sunlight by highly reflective material on the surface, possibly ice," Christopher Russell, principal investigator for the Dawn mission from the University of California, Los Angeles, said recently.
