The UN's International Agency for Research on Cancer (IARC) said Friday (20 March) that three pesticides, including the popular weed killer Roundup, were "probably" carcinogenic and two others, which have already been outlawed or restricted, were "possibly" so.

IARC classified the herbicide glyphosate – the active ingredient in Roundup – and the insecticides malathion and diazinon as "probably carcinogenic" on the basis of "limited evidence" of cancer among humans.

A cancer drug could be made 50 times more effective by a chemical found in stinging nettles and ants, new research finds. Researchers at the University of Warwick found that when the chemical, Sodium Formate, is used in combination with a metal-based cancer treatment it can greatly increase its ability to shut down cancer cells.

Mutiny on the Bounty is a tale about the Royal Navy ship Bounty. On April 28, 1789, Fletcher Christian led sailors in a mutiny against their captain, Lieutenant William Bligh. So the story goes, the captain was set afloat in a small boat along with crew members who were loyal to him, while the mutineers settled on Pitcairn Island or Tahiti and burned Bounty off Pitcairn to avoid detection.

Today Pitcairn island’s population is about 50 people, including descendants of Fletcher Christian, and the surrounding waters where the Bounty supposedly went down in flames has just become the world’s largest contiguous ocean reserve.

This is great news for the sanctity of the Pacific ocean and its inhabitants.

Investigadores de los Laboratorios Nacionales Sandia han ayudado a desentrañar un antiguo misterio de la astrofísica: ¿por qué el hierro se encuentra por todo el manto de la Tierra, en la región de más o menos 2,000 millas de espesor entre el núcleo de la Tierra y su corteza?

A primera vista, parecía más razonable que el hierro que llega de colisiones entre la Tierra y planetesimales (que van desde varios metros a cientos de kilómetros de diámetro), durante las últimas etapas de formación de la Tierra, debería haber sido impulsado como bala directamente al núcleo de la Tierra, donde el hierro ya existe en gran cantidad.

How exactly DID Burmese Pythons get so numerous in the Everglades?  Were they released by owners who didn't want them and they found they liked the ecosystem?

Nearly 80 percent of radio-tracked marsh rabbits that died in Everglades National Park in a recent study were eaten by Burmese pythons, according to a new publication by University of Florida and U.S. Geological Survey researchers.  

A year later, there was no sign of a rabbit population in the study area.  The study demonstrates that Burmese pythons are now the dominant predator of marsh rabbits, and likely other mid-sized animals in the park, potentially upsetting the balance of a valuable ecosystem.
