Putting bedbugs to bed forever

Posted: 24 Dec 2014 07:31 AM PST

A team of scientists has found a way to conquer the global bedbug epidemic. By lending their own arms for thousands of bed bug bites, they have finally found the solution -- a set of chemical attractants, or pheromones, that lure the bedbugs into traps, and keep them there.

Christmas colors disguise gliding lizards in the rainforest

By mimicking the red and green colors of falling leaves, Bornean lizards avoid falling prey to birds whilst gliding, new research has found.

Ants show left bias when exploring new spaces

Posted: 24 Dec 2014 07:31 AM PST

Unlike Derek Zoolander, ants don't have any difficulty turning left. New research has found that the majority of rock ants instinctively go left when entering unknown spaces. Around ten percent of people are left-handed and brain lateralization is widespread in other vertebrates.

European fire ant impacts forest ecosystems by helping alien plants spread

Posted: 24 Dec 2014 07:31 AM PST

An invasive ant species that has become increasingly abundant in eastern North America not only takes over yards and delivers a nasty sting, it's helping the spread of an invasive plant species. The ants are very effective dispersers of invasive plant seeds and new research suggests that together they could wreak havoc on native ecosystems.

The ants that conquered the world

Posted: 24 Dec 2014 07:31 AM PST

About one tenth of the world's ants are close relatives; they all belong to just one genus out of 323, called Pheidole. New research suggests that Pheidole evolved the same way twice, once to take over the New World, and then again to take over the Old World.

Scrapie could breach the species barrier

Posted: 24 Dec 2014 07:30 AM PST

The pathogens responsible for scrapie in small ruminants (prions) have the potential to convert the human prion protein from a healthy state to a pathological state, researchers have discovered for the first time. In mice models reproducing the human species barrier, this prion induces a disease similar to Creutzfeldt-Jakob disease. These primary results stress the necessity to reassess the transmission of this disease to humans.   

Trial confirms Ebola vaccine candidate safe, equally immunogenic in Africa

Posted: 23 Dec 2014 05:40 AM PST

Two experimental DNA vaccines to prevent Ebola virus and the closely related Marburg virus are safe, and generated a similar immune response in healthy Ugandan adults as reported in healthy US adults earlier this year. The findings are from the first trial of filovirus vaccines in Africa.

Devising a way to count proteins as they group

Posted: 22 Dec 2014 01:54 PM PST

A new study reports on an innovative theoretical methodology to solve 'the counting problem,' which is key to understanding how proteins group and perform their vital functions within the human body.
