A sticky drop of nectar clinging to the tip of a hummingbird's beak drips into the next flower the bird visits. With that subtle change, the microbes within that drop are now in a new environment, teeming with other microbes. This small example of species forced to coexist in the real world has helped the Fukami Lab at Stanford University unravel the relative importance of two theories scientists have had about how species can live together.

TALLAHASSEE, Fla. -- Global climate change, fueled by skyrocketing levels of atmospheric carbon dioxide, is siphoning oxygen from today's oceans at an alarming pace -- so fast that scientists aren't entirely sure how the planet will respond.

Their only hint? Look to the past.

In a study to be published this week in the journal Proceedings of the National Academy of Sciences, researchers from Florida State University did just that -- and what they found brings into stark relief the disastrous effects a deoxygenated ocean could have on marine life.

Which food type is more environmentally costly to produce -- livestock, farmed seafood, or wild-caught fish?

The answer is, it depends. But in general, industrial beef production and farmed catfish are the most taxing on the environment, while small, wild-caught fish and farmed mollusks like oysters, mussels and scallops have the lowest environmental impact, according to a new analysis.

What we eat has important implications for our health--and for what we spend on healthcare. New research suggests improving the quality of the average American's diet could substantially reduce costs associated with heart disease, diabetes, cancer and other major health problems.

June 10, 2018 - Atlanta, GA - A hospital outbreak of carbapenem-resistant Enterobacteriaceae (CRE) became more worrisome when researchers found resistance genes being shared among unrelated bacteria via plasmids and other mobile genetic elements. This new research will be presented at ASM Microbe, the annual meeting of the American Society for Microbiology, held from June 7th through June 11th in Atlanta, Georgia.

June 9, 2018 - Atlanta, GA - A new study has found that the majority of residents in a rural village of Vietnam harbored multi-drug-resistant (MDR), colistin-resistant E. coli bacteria. Colistin is typically used as a last-resort treatment when there are no other therapy options available. The research is presented at ASM Microbe, the annual meeting of the American Society for Microbiology, held from June 7th to June 11th in Atlanta, GA.

June 9, 2018 - Atlanta, GA - Researchers from the University of Mauritius have shown that factors such as family size, type of diet, multi-usage of towels, among other factors, impact the growth of pathogens on kitchen towels, potentially causing food poisoning. The research is presented at ASM Microbe, the annual meeting of the American Society for Microbiology, held from June 7th to June 11th in Atlanta, Georgia.

June 9, 2018 - Atlanta, GA - Researchers from the Emory Antibiotic Resistance Center describe the first strain of carbapenem-resistant, hypermucoviscous Klebsiella pneumoniae exhibiting colistin heteroresistance and enhanced virulence isolated from a patient in the United States. The research is presented at ASM Microbe, the annual meeting of the American Society for Microbiology, held from June 7th to 11th, in Atlanta, Georgia.

White supremacist marches and xenophobic Twitter rants have brought overt racism to the center of public attention in recent months. Even still, subtle, structural, and systemic forms of racism continue to lurk in what is becoming an increasingly racially diverse United States. In a new collection of scholarly articles, psychological scientists describe research on the enduring and often hidden presence of racism at both the interpersonal and societal levels.

WASHINGTON, June 7, 2018 -- Seashells are made mostly of calcium carbonate, also known as chalk, a mineral soft and crumbly enough to use for sidewalk doodles. Yet seashells are tough and resilient. In this video, Reactions explains why seashells are so different, and why you can't use them to draw on your driveway: https://youtu.be/iUeMxjkSPyM.
