Resistance can spread even without the use of antibiotics

Bacteria are becoming increasingly resistant to common antibiotics. Often, resistance is mediated by resistance genes, which can simply jump from one bacterial population to the next. It’s a common assumption that the resistance genes spread primarily when antibiotics are used,…

New study tracks sulfur-based metabolism in the open ocean

One of the planet’s most active ecosystems is one most people rarely encounter and scientists are only starting to explore. The open ocean contains tiny organisms — phytoplankton — that perform half the photosynthesis on Earth, helping generate oxygen for…

Corals take control of nitrogen recycling

Corals are shown to recycle their own waste ammonium using a surprising source of glucose–a finding that reveals more about the relationship between corals and their symbiotic algae. Symbiosis between corals and algae provides the backbone for building coral reefs,…

Gold nanoparticles shown to be safe and effective treatment for prostate cancer

Biocompatible gold nanoparticles designed to convert near-infrared light to heat have been shown to safely and effectively ablate low- to intermediate-grade tumors within the prostate, according to a study conducted at the Icahn School of Medicine and published in the…

How the herring adapted to the light environment in the Baltic Sea

The evolutionary process that occurs when a species colonizes a new environment provides an opportunity to explore the mechanisms underlying genetic adaptation, which is essential knowledge for understanding evolution and the maintenance of biodiversity. An international team of scientists, led…

Dartmouth receives $12.5 million grant to establish Center for Quantitative Biology

Dartmouth’s Geisel School of Medicine has been awarded a 5-year, $12.5 million grant from the National Institutes of Health (NIH) to establish a Center for Quantitative Biology (CQB) that will bring together and enhance initiatives in computational biology, bioinformatics, and…

Fishing leads to investigation of environmental changes in waterways

A fisherman’s curiosity led to identification of the correlation between microbial communities in recreational freshwater locales and seasonal environmental changes, according to a team of researchers from Penn State. Zachary Weagly, a 2018 graduate of Penn State Berks and an…

Rapid evolution: New findings on its molecular mechanisms

The mechanisms by which new species arise are still not fully understood. What are the evolutionary processes that drive the evolution of new species? Evolutionary biologists traditionally assumed that geographical barriers between animal populations play a decisive role (allopatric speciation):…
