The leaf beetle Ophraella communa can significantly reduce pollen and that may mean a more cost-effective way to reduce allergies and their health care costs using science, while still appealing to activists that otherwise would oppose it.

Ambrosia artemisiifolia, ragweed, causes sneezing and itchy eyes in those with an allergy and aggravates conditions such as asthma and eczema.

Though we convert fat, protein, and carbohydrates to make our common ATP energy currency, microbes have a far more diverse diet.

It turns out a new one can even digest organic compounds like ethane, the second most common component of natural gas.

In the seafloor of the Guaymas Basin at a water depth of 2000 meters in the Gulf of California, a new archaea named Ethanoperedens thermophilum ("heat-loving ethane-eater") has been discovered, and it can also convert carbon dioxide into ethane.

In western countries, there is a lot of talk about globalization and agriculture being negative things about the modern world. They instead offer terms like "agroecology" and "locally grown" and "sustainable."

To paraphrase U.S. President Eisenhower, when the only hoe you have ever seen is in a Twitter posting by an organic industry trade group, farming is easy.

Science is often easy in hindsight and two years from now we will likely know the evolution of SARS-CoV-2 from bats to humans. For now, it is mostly speculation.

An intermediate animal host may have been snakes or pangolins, but the real common ancestor of SARS-CoV-2 goes back for as long as coronavirus was recognized as distinct from the common cold - the 1960s.

The early "evolutionary paths" SARS-CoV-2, the 2019 coronavirus that leads to COVID-19 in humans have been traced using phylogenetic network techniques and shows how it spread from Wuhan to Europe and America.

While there are too many rapid mutations in coronaviruses, they are in the same family as the common cold, to ever find a Patient Zero or even a settled family tree, analysis of the first 160 complete virus genomes to be sequenced from human patients show the original spread of the new coronavirus through its mutations. 

Though they are called giant viruses they're still among the tiniest denizens of the microbiome. A few genes' worth of DNA or RNA folded into a shell so small you need an electron microscope to see it, more like a stripped-down husk of an organism.

Giant viruses are ten times the size of their more compact cousins and with hundreds or even thousands of genes, so unlike the rest of the family that until first cataloged in 1992, researchers had dismissed them as bacteria.
