Flowers of the genus Orthosia are small but rich in detail. After decades of research, plant systematics researchers at the University of Bayreuth have now presented a complete overview of the genus for the first time. A total of 55 species were identifie

University of Minnesota researchers developed and reported processes for the first time to infect corn plants in the field with the corn tar spot pathogen, a relatively new disease threatening corn production across the United States.

Weeds are a pesky irritant for most home gardeners, but in large agricultural settings, weeds can pose an especially deadly problem. For example, Amaranthus palmeri, known as Palmer's pigweed, has evolved in many areas to be completely resistant to moder

A team of life scientists at Hanyang University, in Korea, working with a pair of colleagues from the Korea Advanced Institute of Science and Technology, has found that fruit flies use crystal cells to transport oxygen throughout their bodies.

A unique method of monitoring river health has uncovered an army of tiny organisms fighting to protect the Brisbane River.

Most coral reef restoration efforts involve restocking reefs with nursery-grown corals. However, if these corals are of the same stock as their wild counterparts, they will be equally vulnerable to the heat stress that caused the bleaching event in the fi

A study of multiple Mycena mushroom species, also known as "bonnets," reported in the journal Cell Genomics on June 27 has found that they have unexpectedly large genomes.

The last population of woolly mammoths was isolated on Wrangel Island off the coast of Siberia 10,000 years ago, when sea levels rose and cut the mountainous island off from the mainland.

Researchers at the University of Toronto have developed a deep-learning model, called PepFlow, that can predict all possible shapes of peptides—chains of amino acids that are shorter than proteins, but perform similar biological functions.

During recent periods of unusually warm water in the Gulf of Alaska, young Pacific cod in near shore safe havens where they typically spend their adolescence did not experience the protective effects those areas typically provide, a new Oregon State Unive

Researchers predict that climate change will drive a substantial redistribution of brown seaweeds and seagrasses at the global scale. The projected changes are alarming due to the fundamental role of seaweeds and seagrasses in coastal ecosystems, and prov

In a new study, scientists describe three new, but long-extinct, walnut species on an island above the Arctic Circle. The fossils were discovered further north than any known walnut species, living or extinct, and represent some of the oldest-known record
