Throughout life's history on earth, biological diversity has gone through ebbs and flows -- periods of rapid evolution and of dramatic extinctions. We know this, at least in part, through the fossil record of marine invertebrates left behind since the Cambrian period.
Insects and diseases that damage crops are probably present in many places thought to be free of them, new research shows. Pests that have not been reported in a certain area are usually assumed to be absent, but analysis by the University of Exeter shows many pests are "currently unobserved, but probably present" (a likelihood of more than 75%).
If cicadas made horror movies, they'd probably study the actions of their counterparts plagued by a certain psychedelic fungus.
Some MRSA infections could be tackled using widely-available antibiotics, suggests new research from an international collaboration led by scientists at the University of Cambridge and the Wellcome Sanger Institute.
A new study by researchers at the University of Illinois suggests that three of the phenolic compounds in cocoa bean shells have powerful effects on the fat and immune cells in mice, potentially reversing the chronic inflammation and insulin resistance associated with obesity.
Virginia Tech researchers discovered that wheat plants "sneezing" off condensation can vastly impact the spread of spore-borne diseases, such as wheat leaf rust, which can cause crop yield losses of up to 20 percent or more in the United States and higher average losses in less developed agricultural nations.
A team of researchers has carried out a detailed study of the genomes of ruminants, giving new insight into their evolution and success.
University of Cincinnati biologist George Uetz long suspected the extravagant courtship dance of wolf spiders made them an easy mark for birds and other predators.
New UC Riverside-led research settles a longstanding debate about whether the most ancient animal communities were deliberately mobile. It turns out they were, because they were hungry.
Research carried out by an international team led by scientists from Ludwig-Maximilians-Universitaet (LMU) in Munich and the University of Tübingen reveals aspects of the drinking and dietary habits of the Celts, who lived in Central Europe in the first millennium BCE.
A collaborative team of scientists from the US and Australia has named a new plant species from the remote Outback. Bucknell University biology postdoctoral fellow Angela McDonnell and professor Chris Martine led the description of the plant that had confounded field biologists for decades because of the unusual fluidity of its flower form. The discovery, published in the open access journal PhytoKeys, offers a powerful example of the diversity of sexual forms found among plants.
GAINESVILLE, Fla. --- Feet from the raw bars and sherbet-colored condominiums of Florida's Cedar Key, researchers discovered a new species of egg-sucking sea slug, a rare outlier in a group famous for being ultra-vegetarians.
Sea otters have low genetic diversity, which could endanger their health as a species, a UCLA-led team of life scientists has discovered. The findings have implications for the conservation of rare and endangered species, in which low genetic diversity could increase the odds of extinction.
Affecting around 115,000 people in the UK alone, Crohn's Disease is a lifelong condition which sees parts of the digestive system become inflamed. There is no precise cure and causes are believed to vary. But one indicator of the condition - an abnormal reaction of the immune system to certain bacteria in the intestines - has had new light shed on it thanks to scientists at the University of Plymouth.
Most fishing communities from North Carolina to Maine are projected to face declining fishing options unless they adapt to climate change by catching different species or fishing in different areas, according to a study in the journal Nature Climate Change.
