Is Chagas disease the ‘new AIDS’?

A life-threatening parasite transmitted by a biting Triatome bug can cause a person’s heart and intestines to swell and burst — but early symptoms are hard to detect.

New “Bumble Bee Gecko” Discovered in Papua New Guinea

by USGS staff

Biologists from the Papua New Guinea National Museum and the U.S. Geological Survey have discovered a new species of gecko, adorned like a bumblebee with black-and-gold bands and rows of skin nodules that enhance its camouflage on the tropical forest floor.

Specimens of the lizard, which measures about 5 inches from head to tail, were collected in May 2010 in Sohoniliu Village on Manus Island in Papua New Guinea. Herpetologists George Zug of the Smithsonian’s National Museum of Natural History and Rober Fisher  of the USGS Western Ecological Research Center described the new species in a report published in “Zootaxa” this month.

“We’ve officially named it Nactus kunan for its striking color pattern — kunan means ‘bumblebee’ in the local Nali language,” Fisher says. “It belongs to a genus of slender-toed geckos, which means these guys don’t have the padded, wall-climbing toes like the common house gecko…”

Fisher found two individuals of the bumblebee gecko on Manus Island in 2010 and analyzed their genetics to show that the lizards were new and distinctive. Two additional species were found that trip, and the specimens await further analysis…

Forest guards told to shoot poachers on sight after rash of tiger killings

India hits back against hunters who sell body parts to Asia for use in traditional medicines

by Andrew Bundcombe

Confronted by the killing of at least eight tigers in the state so far this year, officials in the western state of Maharashtra, whose capital is Mumbai, have told forest guards they will have the same legal protection as police officers who have to use their guns on duty.

According to a report in The Indian Express newspaper, the state’s Forest Minister, Patangrao Kadam, told officials this week that he wanted to do whatever was required to protect the guards. “Human rights groups come in the way if there is any such action, but there is a need to save the tigers,” he said. “If the staff spot poachers committing an offence, they have been given orders to shoot on sight. They should sound a warning asking them to surrender, but if the poachers fail to do so, they should be shot.”

The orders giving forest guards legal protection should they need to use weapons were apparently first issued in 2006, but reports suggest that a number of guards felt uneasy about using their guns. Most of the guards are poorly trained and badly paid and there had been cases where guards had been charged for firing a weapon…

New Frog Species From Panama, Dyes Your Fingers Yellow

by PhysOrg staff

A new bright yellow frog species has been found in the mountains of western Panama. The frog belongs to a species-rich group of frogs, the so called rainfrogs that lack a tadpole stage, but develop directly as little frogs inside the egg.

The , that measures less than 2 cm, was discovered by Andreas Hertz and his colleagues, who are reptile and amphibian specialists at the Senckenberg Research Institute in Frankfurt am Main; Germany. They discovered it in 2010 during several field trips to the Serranía de Tabasará of western Panama a highly understudied part of the Panamanian central mountain range.

“Although we recognized that the male mating call of this differs from all what we had heard before and therefore suspected it to be new, much effort was involved to finally spot it in the dense vegetation”, said Hertz. “When we finally caught the first individuals by hand, we noticed that it dyes one’s fingers yellow when it is handled. The scientific name (Diasporus citrinobapheus) of this new frog refers to this characteristic and means yellow dyer rainfrog…”
