Hace unos 252 millones años, la vida en la Tierra se derrumbó en una forma espectacular y sin precedentes, ya que más del 96 por ciento de las especies marinas y el 70 por ciento de las especies terrestres desaparecieron en un instante geológico. La llamada extinción de finales del Pérmico o más comúnmente, la "Gran Mortandad", sigue siendo el evento de extinción más grave en la historia de la Tierra.

A bigger more hearty catnip plant – whose enriched oil not only promises to drive cats crazy with pleasure but also may be a safer, more effective mosquito repellent – has been developed for specialized commercial farmers by Rutgers University.

A super catnip has been developed by Rutgers that will allow commercial farmers to grow bigger yields at more affordable prices.

The Rutgers New Jersey Agricultural Experiment Station (NJAES), which has spent more than a decade developing the new breed, CR9, for the insect repellant and pet toy industries recently licensed the product to Ball Horticulture, an Illinois company that will produce the seeds for commercial farmers.

With careful management, selectively logged tropical Amazonian forests can recover their carbon stocks within a cutting cycle of 20 to 30 years, according to researchers who report their findings in the Cell Press journal Current Biology on September 21. The findings show that sustainably logged tropical forests continue to play a key role in global carbon sequestration, with important implications for global climate.

The sheer vastness of the oceans on this planet make it seem almost impossible that our actions could bring them to the point of no return, but a new report has found that we are causing an alarming decline of marine ecosystems and the species who rely on them.

According to the World Wildlife Fund‘s (WWF) recently released Living Blue Planet Report, marine populations have declined by an astonishing 49 percent between 1970 and 2012, with with some fish species, including tuna, declining by almost 75 percent.

There is mounting data to suggest that hydraulic fracturing (fracking) can have adverse affects on the environment. A new study, however, suggests that populations living close to fracking sites also have a higher incidence of health complications.
