A decline in the element molybdenum across the planet's oceans preceded a significant extinction event approximately 183 million years ago, new research shows.
Antioxidant flavonols linked to slower memory decline
People who eat or drink more foods with antioxidant flavonols, which are found in several fruits and vegetables as well as tea and wine, may have a slower rate of memory decline, according to a new study.
Put the kettle on! How black tea (and other favorites) may help your health later in life
A daily cup of tea could help you to enjoy better health late in life -- however if you're not a tea drinker, there are other things you can add to your diet. The key is flavonoids, which are naturally occurring substances found in many common foods and beverages such...
Glass-like shells of diatoms help turn light into energy in dim conditions
A new study has revealed how the glass-like shells of diatoms help these microscopic organisms perform photosynthesis in dim conditions. A better understanding of how these phytoplankton harvest and interact with light could lead to improved solar cells, sensing devices and optical components.
Earth might be experiencing 7th mass extinction, not 6th
Earth is currently in the midst of a mass extinction, losing thousands of species each year. New research suggests environmental changes caused the first such event in history, which occurred millions of years earlier than scientists previously realized.
Intestinal microorganisms influence white blood cell levels in blood
Intestinal bacteria composition is crucial to driving the recovery of neutrophils counts in the blood of mice following treatments such as stem cell transplants or chemotherapy.
Satellites cast critical eye on coastal dead zones
Scientists have found a new and better way to use remote sensing to understand where coastal dead zones are and predict changes.
What shapes the composition of microbes in a warbler’s gut?
Differences among the collection of bacteria and other microorganisms that live within birds' digestive tracts -- their gut microbiomes -- are not primarily driven by diet diversity, contrary to a recently proposed hypothesis. Instead, a team of researchers found that evolution may play a larger role in explaining these differences,...
Study shows superbugs in the environment rarely transfer over to humans: Hospitals are more risky than farms
A study has investigated the spread of Klebsiella bacteria between humans and the environment.
Mapping Lyme disease out west
Tick bites can transmit Lyme disease. But even knowing where these ticks live doesn't necessarily mean you can predict the disease in humans. It's only one part of a broader picture which includes human behavior and the habits of the parasite's carriers.
