Researchers are investigating a new material that might help in nuclear fuel recycling and waste reduction by capturing certain gases released during reprocessing. Conventional technologies to remove these radioactive gases operate at extremely low, energy-intensive temperatures. By working at ambient temperature, the new material has the potential to save energy, make reprocessing cleaner and less expensive. The reclaimed materials can also be reused commercially.

Convertir el CO2 en roca para mitigar el cambio climático
Un equipo internacional de científicos ha encontrado una forma potencialmente viable para eliminar el CO2 antropogénico (causado o influenciado por los seres humanos): Convertirlo en roca. El estudio, publicado en la revista Science, ha demostrado por primera vez que el dióxido de carbono, un gas de efecto invernadero (CO2), puede ser permanente y rápidamente eliminado de la atmósfera, mediante su inyección en roca volcánica. El CO2 reacciona con la roca circundante, formando minerales ambientalmente benignos.
Fish use tools!
Fish: charming, but not terribly bright, right? That’s been the party line for years, but it turns out that it’s not quite accurate.
Some fish actually use tools, and as researcher Culum Brown points out, the lack of studies on fish populations means that we don’t actually know the extent this skill. Opening our eyes a little might reveal some fascinating new information about creatures we’ve traditionally identified as sitting at the lowest rung of animal life — even some vegetarians don’t see a conflict with including fish in their diets!
The first documented instance of tool use by a fish occurred in 2011, when a diver noticed a blackspot tuskfish doing something odd as he drifted along the Great Barrier Reef. When the diver investigated, he found that the fish was using a rock to crack open clam shells in order to access the meat inside. It showed a degree of resourcefulness that researchers hadn’t expected to see in fish — and it wasn’t the only intelligent tuskfish behavior.
Uso de las tortugas del lago Michigan para medir la contaminación de los humedales
Décadas de depositar residuos industriales no regulados en las zonas de los Grandes Lagos han creado una serie de problemas ambientales y de vida silvestre. Ahora parece que las tortugas pintadas del lago Michigan podrían ser una fuente útil para medir la contaminación resultante.
Los investigadores del laboratorio de Gary Lamberti, profesor de ciencias biológicas y director del Laboratorio de Ecología de Corrientes y del Humedales en la Universidad de Notre Dame, están trabajando en el proyecto federal “Iniciativa de Restauración de los Grandes Lagos”
Popcorn-like fossils provide evidence of environmental impacts on species numbers
The number of species that can exist on Earth depends on how the environment changes, according to new research led by the University of Southampton.
By analysing the fossil record of microscopic aquatic creatures called planktonic foraminifera, whose fossil remains now resemble miniaturised popcorn and date back millions of years, the research provided the first statistical evidence that environmental changes put a cap on species richness.
Environmental crimes increasing according to the UN
A new report by the United Nations Environment Program (UNEP) and Interpol has highlighted the sophistication and growth of environmental crimes across the world. These crimes range from the illegal trade of wildlife, illegal mining, illegal forestry and fishing. And despite our growing global attention towards conservation, these crimes have jumped 26 percent in the past two years alone.
The report highlights the criminal fluidity of these trades. They say that transnational crime rings are no longer focusing on just one flow of illicit trade; rather, “criminals coordinate, evade or even shift their focus from drugs, human trafficking, counterfeit products and arms to any new opportunity – hazardous waste and chemicals, forest products, pangolins, giant clams, minerals and illegally extracted gold.”
According to the UNEP, the reasons behind this rise is linked to both increasing demand, primarily in Asia, as well as poverty in the regions where the smuggling of these goods take place. Local wildlife authorities across Africa, which often scrape by on a minimal budget, must constantly adapt to new methods and new extremes employed by poachers.
