Natural compound 2HF treats leishmaniasis infections, study finds

Current treatment options for the parasitic disease leishmaniasis are largely ineffective, expensive, and tend to be plagued by resistant parasites and side effects. Now, researchers have showed that a natural flavonoid is effective at treating Leishmania amazonensis infections.

Modeling the microbiome

The gut microbiome -- the world of microbes that inhabit the human intestinal tract -- has captured the interest of scientists and clinicians for its critical role in health. However, parsing which of those microbes are responsible for effects on our wellbeing remains a mystery.

Report reveals link between air pollution and increased risk for miscarriage

Researchers found women living along the Wasatch Front -- the most populous region in the state of Utah -- had a higher risk (16 percent) of miscarriage following short-term exposure to elevated air pollution.

Fine-tuning renewables could help Texas balance energy resources

Soft tissue shows Jurassic ichthyosaur was warm-blooded, had blubber and camouflage

An ancient, dolphin-like marine reptile resembles its distant relative in more than appearance, according to an international team of researchers. Molecular and microstructural analysis of a Stenopterygius ichthyosaur from the Jurassic (180 million years ago) reveals that these animals were most likely warm-blooded, had insulating blubber and used their coloration as camouflage from predators.

Scientists design way to track steps of cells’ development

Scientists have developed a new tool described as a 'flight data recorder' for developing cells, illuminating the paths cells take as they progress from one type to another. This cellular tracking device could one day help scientists guide cells along the right paths to regenerate certain tissues or organs, or help researchers understand the wrong turns some cells might take on their way to becoming cancerous.

Sea invertebrate sheds light on evolution of human blood, immune systems

Botryllus schlosseri, a marine invertebrate that lives in underwater colonies resembling fuzzy pinheads clinging to rocks, has a blood-forming system with uncanny similarities to that of humans, according to scientists.

Navigation system in rodents akin to ancient, open ocean direction-finding

The navigation system used by rodents is similar to that used by Pacific Islanders in finding their way through the open ocean without a compass, a team of neuroscientists has found.

New Zika vaccine effective in preclinical trials

Researchers have successfully developed a vaccine candidate for the Zika virus, showing that it is effective in protecting both mice and monkeys from the infection. Demonstrating the effectiveness of their vaccine candidate in monkeys (non-human primates) is an important milestone because it typically predicts the vaccine will work in humans, enabling further clinical development.
