Tiny Brazilian frogs are deaf to their own calls

Thu, 21 Sep 17 00:00:00 -0700

Pumpkin toadlets, found on the leaf litter of Brazil's Atlantic forest, are among the smallest frogs in the world. An international team from Brazil, Denmark and the United Kingdom, has discovered that two species of these tiny orange frogs cannot hear the sound of their own calls.

Surprising discovery -- how the African tsetse fly really drinks your blood

Thu, 21 Sep 17 00:05:00 -0700

Researchers at the University of Bristol have been taking a close-up look at the biting mouthparts of the African tsetse fly as part of ongoing work on the animal diseases it carries. Using the new high-powered scanning electron microscope in the University's Life Sciences Building, researchers from the Trypanosome Research Group were able to see the rows of sharp teeth and rasps that the fly uses to chew through the skin when it bites.

New research indicates that fish may adapt their behavior to defend against parasite infection. The findings are published in the Journal of Zoology.

NUS scientists combine antimalarial drug with light sensitive molecules for promising treatment of cancer

Mon, 18 Sep 17 00:03:40 -0700

NUS scientists discovered that a combination of artemisinin, which is a potent anti-malarial drug, and aminolaevulinic acid, which is a photosensitizer, could kill colorectal cancer cells and suppress tumor growth more effectively than administering artemisinin alone. This novel combination therapy could also have fewer side effects.

Carbohydrates may be the key to a better malaria vaccine

Fri, 15 Sep 17 00:08:50 -0700

An international research team has shown for the first time that carbohydrates on the surface of malaria parasites play a critical role in malaria's ability to infect mosquito and human hosts. The discovery also suggests steps that may improve the only malaria vaccine approved to protect people against Plasmodium falciparum malaria -- the most deadly form of the disease.
