Plant cell structure could hold key to cancer therapies and improved crops
Can the bend of a banana give us insight into cancer? What does the shape of a rice grain have to do with infertility? The proteins that give plants their shape and structure are also involved in human disease. A team led by researchers at the…

Marine biologists a family history of San Diego's giant kelp over more than four decades
The growth form of giant kelp (Macrocystis pyrifera) is composed of shoots known as stipes instead of branches. From one parent holding fast to the hard bottom might come as many as 150 stipes. Typically, the tips of the biggest kelp bob at the…

Protecting wildlife from genetic collapse with newly identified 'early warning signals'
A new study reveals that habitat fragmentation can lead to sudden “tipping points” where a species’ genetic health unexpectedly collapses after appearing stable for long periods. By merging network theory with population genetics, the research…

How evolution shapes color diversity in coral reef fish
Why does a Caribbean angelfish sometimes resemble its Indo-Pacific cousin, even though they have never lived in the same ocean? Why do coral reefs harbor such a wide range of stripes, spots and patterns? A study conducted by the University of…

Microbial ancestor of complex life was more sophisticated than previously thought, studies suggest
Our single-celled ancestor lived in a world without plants, animals or oxygen-rich oceans. Yet, this seemingly simple microorganism took the first steps toward complex life. From this ancestor emerged all multicellular (complex) life as we know…

New software for biodiversity research enables comprehensive quantification of ecological stability
Intact ecosystems have the capacity for self-regulation, which keeps their complex structure of species—such as animals, plants, fungi and bacteria—in balance. For example, when the population of a species increases, its per capita growth…

Research sheds light on food safety risks in California's Central Coast produce
A five-year study on California’s Central Coast, led by the U.S. Food and Drug Administration and the Western Center for Food Safety at the University of California, Davis, is helping scientists better understand how harmful bacteria can move…

Flipped chromosomal segments drive natural selection, Atlantic silversides study shows
When a species lives in two distinct types of habitats, individuals with traits better suited to each habitat will thrive and reproduce, naturally selecting descendants with those traits. But what about mobile aquatic species that live across a…
