In wild soil, predatory bacteria grow faster than their prey
3hPredatory bacteria—bacteria that eat other bacteria—grow faster and consume more resources than non-predators in the same soil, according to a new study out this week from Northern Arizona University. These active predators, which use wolfpack-like behavior, enzymes, and cytoskeletal 'fangs' to hunt and feast on other bacteria, wield important power in determining where soil nutrients go. The resu
Space tourism—20 years in the making—is finally ready for launch
3hFor most people, getting to the stars is nothing more than a dream. On April 28, 2001, Dennis Tito achieved that lifelong goal—but he wasn't a typical astronaut. Tito, a wealthy businessman, paid US$20 million for a seat on a Russian Soyuz spacecraft to be the first tourist to visit the International Space Station. Only seven people have followed suit in the 20 years since, but that number is pois

Population genomic evidence of Plasmodium vivax Southeast Asian origin
3hPlasmodium vivax is the most common and widespread human malaria parasite.

Do senior faculty publish as much as their younger colleagues?
1dAn Academic Analytics Research Center (AARC) study published in the journal Scientometrics found that senior faculty (scholars who earned their terminal degree 30 or more years ago) research publication activity exceeded expectations based on age cohort population for book chapters and book publications, and senior scholars largely kept pace in terms of journal article publications. "Across all di
4 hep C drugs make remdesivir 10x better at fighting coronavirus
1dFour drugs used to treat hepatitis C render remdesivir 10 times better at inhibiting the coronavirus in cell cultures, according to a new study. Remdesivir is currently the only antiviral drug approved in the US for treating COVID-19 patients. The results, published in Cell Reports , indicate that a mixture containing remdesivir and a repurposed hepatitis C virus (HCV) drug could potentially func
Metabolite fumarate can reveal cell damage: New method to generate fumarate for MRI
1dA promising new concept presented by an interdisciplinary research team paves the way for major advances in the field of magnetic resonance imaging (MRI). Their new technique could significantly simplify hyperpolarized MRI. The proposal involves the hyperpolarization of the metabolic product fumarate using parahydrogen and the subsequent purification of the metabolite.
Blue Origin Challenges NASA Selection of SpaceX for Lunar Lander
