Why do we love carbs? The origins predate agriculture and maybe even our split from Neanderthals

If you’ve ever struggled to reduce your carb intake, ancient DNA might be to blame. It has long been known that humans carry multiple copies of a gene that allows us to begin breaking down complex carbohydrate starch in the mouth, providing the first step in metabolizing starchy foods like bread and pasta. However, it […]

Microbes in mouth reflect lifestyle choices

Lifestyle can shape the composition of beneficial bacteria and other microorganisms within the mouth, according to a new study led by Penn State biologists. The international team revealed how the “oral microbiome” differs over a range of subsistence strategies — from nomadic hunter gatherers to farmers to industrialized groups — and found that lifestyle, as […]

Fossil of huge terror bird offers new information about wildlife in South America 12 million years ago

Researchers including a Johns Hopkins University evolutionary biologist report they have analyzed a fossil of an extinct giant meat-eating bird — which they say could be the largest known member of its kind — providing new information about animal life in northern South America millions of years ago. The evidence lies in the leg bone […]

Detailing organelle division and segregation in Plasmodium falciparum

The malaria-causing parasite, P. falciparum, replicates through schizogony, a tightly orchestrated process where numerous daughter parasites are formed simultaneously. Proper division and segregation of one-per-cell organelles, like the mitochondrion and apicoplast, are essential, yet remain poorly understood. We developed a new reporter parasite line that allows visualization of the mitochondrion in blood and mosquito stages. […]
