For the first time, scientists have visualized the fine details of bacterial microcompartment shells -- the organisms' submicroscopic nanoreactors, which are comprised completely of protein.
It's a tiny marine invertebrate, no more than 3 millimeters in size. But closely related to humans, Botryllus schlosseri might hold the key to new treatments for cancer and a host of vascular diseases.
The anchors that hold Venus' flower basket sea sponges to the ocean floor have an internal architecture that increases their ability to bend, according to a new study. Understanding that natural architecture could inform future human-made materials.
A newly published article in Environmental Toxicology and Chemistry reports that pyrethroids, a common household pesticide known to cause skin irritation, headache, dizziness and nausea, persists in the home for up over one year.
Ancestors of the iconic New Zealand Christmas Tree, P?hutukawa, may have originated in Australia, new fossil research from the University of Adelaide suggests.
Microbes are widely used to break down plant biomass into sugars, which can be used as sustainable building blocks for novel biocompounds. Getting the right microbial community for this process is still a matter of trial and error. New insights by University of Groningen microbial ecologist Diego Javier Jiménez and colleagues could make a rational design possible. They argue this point in an opinion paper published in the journal Trends in Microbiology on June 22.
A study of historic whaling records has revealed there were warning signs that populations of commercially harvested whales were heading for global collapse up to 40 years before the event.
The absence of a single dominant bumblebee species from an ecosystem disrupts foraging patterns among a broad range of remaining pollinators in the system -- from other bees to butterflies, beetles and more, field experiments show.
The fossil of an early snake-like animal -- called Lethiscus stocki -- has kept its evolutionary secrets for the last 340-million years. Now, an international team of researchers, led by the University of Calgary, has revealed new insights into the ancient Scottish fossil that dramatically challenge our understanding of the early evolution of tetrapods, or four-limbed animals with backbones.
Algae dominate the oceans that cover nearly three-quarters of our planet, and produce half of the oxygen that we breathe. And yet fewer than 10 percent of the algae have been formally described in the scientific literature, as noted in a new review co-authored by Carnegie's Arthur Grossman.
