Alaskan waters are a critical fishery for salmon. Complex marine food webs underlie and sustain this fishery, and scientists want to know how climate change is reshaping them. But finding samples from the past isn't easy.

A massive new global study led by the University of Copenhagen and University of Hohenheim has examined the effects of diversified agriculture. The conclusion is abundantly clear—positive effects increase with every measure, while negative effects are har

A study reported in the journal acta ethologica has recorded the use of ultrasound by amphibians for the first time in South America. It also describes the first documented case of the use of ultrasound for defense against predators, in a distress call of

Researchers at the University of Colorado Anschutz Medical Campus have discovered a mechanism by which a bacterial virus undermines the virulence of Salmonella, allowing the host a chance to rehabilitate.

Scientists say the relocation of coral away from the path of a new wastewater pipe has been a success and shows how coral can be moved to reduce the impact of developments and natural disasters.

Currently 14% of the world's 11,000 bird species are threatened with extinction. A new study assessed the populations of bird species across a spectrum of landscapes from pristine habitats to human-dominated environments.

Sex pheromones are vital in facilitating the chemical communication that underpins insect courtship and mating behavior. Among female American cockroaches (Periplaneta americana), two key volatile sex pheromone components, periplanone-A (PA) and periplano

A new study has confirmed that the invasive A. yasumatsui, known as Cycad Aulacaspis Scale (CAS), stands alone as the greatest threat to the existence of the Cycas micronesica species. The endemic cycad species to Micronesia has thrived in the region for

New research could pave the way to developing cancer drugs targeting an enzyme that inhibits ferroptosis, a type of cell death. Cancer cells that are resistant to anticancer drugs are known to be vulnerable to ferroptosis. Therefore, agents that effective

Due to their simple body structure with a limited number of cell types, freshwater polyps (Hydra) can be used to study many fundamental processes of life. In recent years, Hydra has also experienced a renaissance as a model organism for neuroscience—thank

A study led by a researcher at the University of Stirling has identified microscopic organisms that may be crucial to the survival of coral reefs.

While climate change has led to an increase in the abundance of octopuses, heat stress from projected ocean warming could impair their vision and impact the survivability of the species.
