Ammonites were not in decline before their extinction, scientists have found.

Maternal immunity refers to the immunity transferred across the placenta, colostrum, milk or eggs from mother to offspring. It plays a key role in protecting the vulnerable offspring against pathogenic attacks, and is present in nearly all vertebrates and

A widely-used Living Planet Index (LPI) characterizes the average change in population sizes of vertebrates and is considered one of the main indicators of the state of the planet.

An international team of researchers, led by the Leibniz Institute of Virology (LIV), have uncovered crucial details on how herpesviruses exit the cell nucleus without compromising the integrity of the nuclear envelope. Herpesvirus infections are widespre

The Coral Triangle, also known as the Indo-Australian Archipelago, is renowned for having the greatest marine biodiversity on our planet. Despite its importance, the detailed evolutionary history of this biodiversity hotspot has remained largely a mystery

For a billion years, single-celled eukaryotes ruled the planet. Then around 700 million years ago during Snowball Earth—a geologic era when glaciers may have stretched as far as the Equator—a new creature burst into existence: the multicellular organism.

Research spearheaded by four biologists within the College of Arts and Sciences at Indiana University Bloomington has uncovered a new regulatory mechanism shared by many bacteria, which may have profound implications for anti-bacterial control measures in

The deep sea is the largest living space on Earth, but many of the animals and habitats far beneath the ocean's surface remain shrouded in mystery. MBARI's advanced underwater robots, including remotely operated vehicles (ROVs), are helping survey life

In a study appearing in Nature, an international team of researchers led by the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, reconstructed the evolutionary history and global spread of malaria over the past 5,500 years, identify

A study reveals how auxin and sucrose metabolism regulate bulbil initiation in Lilium lancifolium. By manipulating auxin levels and examining key sucrose metabolism genes, researchers found that low auxin concentrations enhance bulbil formation. This disc

Aquaculture has been a traditional and vibrant farming practice in China for 8,000 years. In the 21st century, the success of Chinese aquaculture and its contributions to global food security have attracted extensive attention around the world. Aquacultur

A new machine-learning system developed at the University of Alaska Fairbanks can automatically produce detailed maps from satellite data to show locations of likely beetle-killed spruce trees in Alaska, even in forests of low and moderate infestation whe
