The original purpose of the 2022 study was to look at the impact of pesticide residues in soil on queen bees hibernating underground.
Researchers have discovered toxic protein particles, shaped like umbrellas, that soil bacteria known as Streptomyces secrete to squelch competitors, especially others of their own species.
You might be getting more sleep than you think.We all know that sleep is essential for our mental and physical wellbeing. And yet, one in three adults in the U.S. report not getting enough of it, according to the U.S. Centers for Disease Control and Prevention.In the short term, not getting enough sleep can take a toll on our attention span, judgment, emotions and cognitive function. But over time, chronic sleep deprivation can contribute to heart disease, obesity, neurodegenerative disorders...
Modern biology textbooks assert that only bacteria can take nitrogen from the atmosphere and convert it into a form that is usable for life. Plants that fix nitrogen, such as legumes, do so by harboring symbiotic bacteria in root nodules. But a recent discovery upends that rule.
While it's common knowledge that mountaintops are colder than the valleys below, a new University of Vermont (UVM) study is flipping the script on what we know about forests and climate.
Bacteria like E. coli and salmonella can home in on blood, a process called 'bacterial vampirism.' In people with IBD who have small cuts in the gut, these bacteria can easily find their way into the blood.
While disinfecting spacecraft headed for Mars, NASA found a stubborn type of bacteria that was tough to clean but great at withstanding UV radiation.
At least one bumblebee species can survive underwater, scientists have found after a mishap led to an experiment. A study by researchers in Canada has found when hibernating, common eastern bumblebee queens can survive being submerged in water for a week with no apparent issues. Research began after Dr Sabrina Rondeau, of the University of Guelph in Ontario, made a mistake during a previous experiment. After storing a shipment of 300 hibernating common eastern bumblebee queens in a refrigerator,...
Since the 1970s, modern antibiotic discovery has been experiencing a lull. Now the World Health Organization has declared the antimicrobial resistance crisis as one of the top 10 global public health threats.
Learning from an experience, remembering an anecdote or changing an attitude are examples that reveal how all our behavior is the result of the exchange of chemical compounds—neurotransmitters—between neurons. Unraveling what exactly happens at the molecular level when neurons "talk" to each other at synapses is crucial for understanding the human brain in general and, in particular, for helping to solve mental health problems.
Sometimes the processing that makes food safe can compromise flavor and nutrients, but food scientist Jennifer Acuff is looking for a way to make food safe and minimize loss of quality.
(The Center Square) -- When bees visit flowers, they get food and emit waste. Bees release microbes during this process, which can alter their gut microbiome. Scientists thought that monocultures such as sunflower fields would lead to the restructuring and homogenization of bees' gut bacteria. It turns out, not so much. However, bees visiting such monocultures didn’t lose gut biome diversity, according to Lauren Ponisio, an assistant biology professor in the College of Arts and...
