Middle Earth preserved in giant bird dung

Mon, 12 Feb 18 00:07:40 -0800

While the giant birds that once dominated New Zealand are all extinct, a study of their preserved dung (coprolites) has revealed many aspects of their ancient ecosystem, with important insights for ongoing conservation efforts.

Human antibodies undermine parasite sex

Thu, 08 Feb 18 00:13:40 -0800

Some people develop an immune response following a malaria infection that stops them from infecting other mosquitos. The antibodies that these people produce are sucked up by the mosquito and destroy the malaria parasite in the mosquito's stomach. Researchers from Radboud university medical center discovered that 1 in 25 malaria patients prevent the disease from spreading in this way. They also unraveled the defense proteins responsible, and these could be used to make a vaccine.

Competing for blood: How ecologists are solving infectious disease mysteries

Thu, 08 Feb 18 00:02:20 -0800

By looking at malaria infections and hookworms as competitors battling over a key resource -- red blood cells -- Princeton ecologists Andrea Graham and Sarah Budischak were able to explain why co-infected patients often got sicker after being dewormed: without the hookworms to keep it in check, the malaria infection ran rampant.

Devoted frog fathers guard their eggs from predators

Wed, 07 Feb 18 00:15:30 -0800

A study led by PhD candidate Mr K. S. Seshadri from the Department of Biological Sciences at the National University of Singapore's Faculty of Science has revealed that male white-spotted bush frogs (Raochestes chalazodes) dedicatedly guard their fertilised eggs from other cannibalistic male frogs and predators. The study confirmed that the adult male white-spotted bush frogs are the sole caregivers of their offspring, predominantly by attending to and guarding the eggs.

White cheeks are more titillating

Tue, 06 Feb 18 00:13:00 -0800

Male blue tits with white cheeks are healthier and more likely to mate with higher quality partners than their counterparts with duller cheek feathers. Having purer white cheeks also indicates that a blue tit was better able to overcome an infection with parasites during the previous year. This is according to Elisa Pérez Badás (Museo Nacional de Ciencias Naturales, Spain) who is lead author of a study published in Springer's journal The Science of Nature.

Sick bees eat healthier

Tue, 06 Feb 18 00:12:00 -0800

James Cook University scientists in Queensland, Australia have shown that sick bees try to look after themselves by eating healthy food.

Dye kills malaria parasites at speed not seen before

Mon, 05 Feb 18 00:06:50 -0800

Research shows that the dye methylene blue is a safe antimalarial that kills malaria parasites at an unprecedented rate. Within two days, patients are cured of the disease and no longer transmit the parasite if they are bitten again by a mosquito. This discovery was made by Radboud university medical center scientists and international colleagues during a research project conducted in Mali. The results will be published in The Lancet Infectious Diseases on Feb. 6.

New evidence shows potential of two drugs to block malaria transmission

Mon, 05 Feb 18 00:10:40 -0800

An international team of researchers has shown that two different compounds-one, an older malaria drug, the other a common laboratory dye with known antimalarial properties-can safely and effectively be added to treatment regimens to block transmission of the most common form of malaria in Africa.

Kitchen hygiene in the spotlight: Do TV cooking shows influence our hygiene behavior?

Fri, 02 Feb 18 00:12:00 -0800

TV shows dealing with all aspects of cooking are popular. They not only convey knowledge and tasty recipes, they also have a high entertainment value. A research project at the Federal Institute for Risk Assessment (BfR) shows, however, that kitchen hygiene often only plays a minor role on TV.

Multidrug-resistant malaria spread under the radar for years in Cambodia

Thu, 01 Feb 18 00:08:30 -0800

The most comprehensive genetic study of malaria parasites in Southeast Asia has shown that resistance to antimalarial drugs was under-reported for years in Cambodia. Wellcome Sanger Institute researchers showed the parasites developed multidrug resistance to first-line treatments extremely rapidly. Reported in The Lancet Infectious Diseases, the study revealed that one main resistant strain had spread aggressively in the five years before clinical resistance was reported. Ongoing genomic surveillance is vital to inform malaria control strategies.

Parasite mimics human proteins to provide 'ready meals' from the gut

Sun, 28 Jan 18 00:08:40 -0800

Giardia parasites -- responsible for one of the world's most common gastric diseases -- mimic human cell functions to break apart cells in the gut and feed off them. The secret behind giardia's success has eluded scientists for more than 300 years. Researchers found that the parasite produces two types of protein that enable it to cut through layers of protective mucus in the gut, breaking the links that knit cells together to access the nutrients within them.
