The notion that septic tanks prevent fecal bacteria from seeping into rivers and lakes simply doesn’t hold water, says a new Michigan State University study.
Are septic tanks doing their job?

UN adopts resolution to attack wildlife crime
Faced with an unprecedented surge in wildlife crime, the UN this week adopted a historic resolution committing all countries to ramp up their collective efforts to end the global poaching crisis and tackle the vast illegal wildlife trade. Initiated by Gabon and Germany and co-sponsored by 84 other nations, the UN General Assembly resolution, Tackling the Illicit Trafficking in Wildlife, is the result of three years of diplomatic efforts and is the first time that every nation has acknowledged the seriousness of wildlife crime and the urgent need to join forces to combat it.
Trophy hunting is not the main reason for declining population of lions in Africa
Africa has half as many lions as 20 years ago - but don't blame trophy hunting
The killing of Zimbabwe's Cecil the Lion has put a welcome spotlight on the alarming decline of Africa's lions, write Lochran Traill & Norman Owen-Smith. But to save the species, we should not obsess about trophy hunting, but tackle much more serious problems - like snaring and habitat fragmentation.
What actually causes aging?
When does aging really begin? Two Northwestern University scientists now have a molecular clue. In a study of the transparent roundworm C. elegans, they found that adult cells abruptly begin their downhill slide when an animal reaches reproductive maturity.
A genetic switch starts the aging process by turning off cell stress responses that protect the cell by keeping important proteins folded and functional. The switch is thrown by germline stem cells in early adulthood, after the animal starts to reproduce, ensuring its line will live on.
La energÃa eólica marina llega a los EE.UU.
Los Estados Unidos marcaron un hito en energía esta semana, ya que comenzó la construcción de un programa piloto para probar la viabilidad económica de la energía eólica marina. Según la Oficina de Energía, unos cuatro millones de MW de potencia esperan en las costas y regiones como la de los Grandes Lagos, donde el viento sopla mucho más fuerte que en tierra firme y donde incluso algunas millas por hora hacen una gran diferencia en las turbinas. Si bien es poco probable que todo ese ese territorio se desarrolle, el generar más energía eólica ayudará a reducir la dependencia del carbón, ayudando a los Estados Unidos a avanzar hacia un futuro de energía limpia y una mayor independencia energética.
