New discovery unravels malaria invasion mechanism      (via sciencedaily.com)     Original source 

A recent breakthrough sheds light on how the malaria parasite, Plasmodium falciparum, invades human red blood cells. The study reveals the role of a sugar called sialic acid in this invasion process. The findings have major implications for malaria vaccine and drug development.

First view of centromere variation and evolution      (via sciencedaily.com)     Original source 

A genomic study of human and selected nonhuman primate centromeres has revealed their unimaginable diversity and speed of evolutionary change. Although centromeres are vital to proper cell replication by assuring faithful transmision of genetic materials when cells divide, the complexity of their genomic organization had been almost impossible to study. The lack of centromere sequences hindered exploration of how these regions help maintain genetic integrity. Now, advanced technologies have shown scientists how greatly centromeres differ in size and structure.

These plants evolved in Florida millions of years ago: They may be gone in decades      (via sciencedaily.com)     Original source 

Scrub mints are among the most endangered plants you've probably never heard of. More than half of the 24 species currently known to exist are considered threatened or endangered at the state or federal level. In a new study, researchers show there are likely more scrub mint species waiting to be scientifically described. And at least one species has been left without federal protection because of a technicality.

When did the chicken cross the road? New evidence from Central Asia      (via sciencedaily.com)     Original source 

An international team of scholars present the earliest clear archaeological and biomolecular evidence for the raising of chickens for egg production, based on material from 12 archaeological sites spanning one and a half millennia. The research indicates that the domestic chicken, now a staple in diets around the world, is not as ancient as previously thought.

Older trees help to protect an endangered species      (via sciencedaily.com)     Original source 

The oldest trees in the forest help to prevent the disappearance of endangered species in the natural environment, according to a new study. This is the case of the wolf lichen -- threatened throughout Europe --, which now finds refuge in the oldest trees in the high mountains of the Pyrenees. This study reveals for the first time the decisive role of the oldest trees in the conservation of other living beings thanks to their characteristic and unique physiology.

Scientists link certain gut bacteria to lower heart disease risk      (via sciencedaily.com)     Original source 

Changes in the gut microbiome have been implicated in a range of diseases including type 2 diabetes, obesity, and inflammatory bowel disease. Now, a team of researchers has found that microbes in the gut may affect cardiovascular disease as well. The team has identified specific species of bacteria that consume cholesterol in the gut and may help lower cholesterol and heart disease risk in people.

New antibiotic class effective against multidrug-resistant bacteria      (via sciencedaily.com)     Original source 

Scientists have discovered a new class of antibiotics with potent activity against multi-drug resistant bacteria, and have shown that it cures bloodstream infections in mice. Two publicly-funded initiatives dedicated to advancing early-stage antibiotic development, ENABLE and ENABLE-2, provided the resources and expert support without which this antibiotic would not have been developed.

Computational tools fuel reconstruction of new and improved bird family tree      (via sciencedaily.com)     Original source 

Using cutting-edge computational methods and supercomputing infrastructure, researchers have built the largest and most detailed bird family tree to date -- an intricate chart delineating 93 million years of evolutionary relationships between 363 bird species, representing 92% of all bird families. The updated tree reveals sharp increases in effective population size, substitution rates and relative brain size in early birds in the aftermath of the mass extinction event that wiped out the dinosaurs 66 million years ago. And by closely examining one of the branches of this tree, researchers found that flamingos and doves are more distantly related than previous genome-wide analyses had shown.

Mosquito detectives track malaria's history      (via sciencedaily.com)     Original source 

A group of researchers is calling on colleagues around the world to join them in what they call 'pathogen prospecting' by tracking down archival specimens of mosquitoes in museums and other collections to examine them for pathogens that would have infected people with malaria while feeding on their blood.
