MIAMI--As the world enters a next wave of the ongoing COVID-19 pandemic, we are aware now more than ever of the importance of a healthy immune system to protect ourselves from disease. This is not only true for humans but corals too, which are in an ongoing battle to ward off deadly diseases spreading on a reef.
The research team found a common insecticide, fipronil, and related compounds were more toxic to stream communities than previous research has found.
Emissions from coal-fired power plants in China are fertilizing the North Pacific Ocean with a metal nutrient important for marine life, according to new findings from a USC-led research team. The researchers believe these metals could change the ocean ecosystem, though it's unclear whether it would be for better or worse.
UC assistant professor Latonya Jackson conducted experiments with North American freshwater fish called least killifish. She found that fish exposed to estrogen in concentrations of 5 nanograms per liter in controlled lab conditions had fewer males and produced fewer offspring. Scientists have found estrogen at as much as 16 times that concentration in streams adjacent to sewage treatment plants.
The critically endangered vaquita has survived in low numbers in its native Gulf of California for hundreds of thousands of years, a new genetic analysis has found. The study found little sign of inbreeding or other risks often associated with small populations.
Sponges are filter feeders that live on particulate matter -- but they can also ingest microscopic fragments of plastics and other pollutants of anthropogenic origin. They can therefore serve as useful bioindicators of the health of marine ecosystems.
For decades, the front lobe of the pituitary was thought to be an evolutionary development that arose in vertebrates from a particular type of embryonic structure located in the ectoderm. USC researchers now present evidence that, in some vertebrates, the endoderm also forms part of the pituitary's front lobe. Findings from the study suggest that the gland may have a longer evolutionary history than previously thought.
Chemicals that haven't been manufactured in the U.S. for years or even decades are still turning up in the bodies of migratory terns in the Great Lakes region, a new study finds. The research focused on three types of compounds: PBDEs, PCBs, and the breakdown products, called metabolites, of DDT.
Marine fish species are migratory in nature and not respectful of human-made territorial boundaries, which represents a challenge for fisheries management as policies tend to focus at the national level. With an average catch of 48 million tonnes per year, and USD $77 billion in annual fishing revenue, these species support critical fisheries, and require international cooperation to manage.
A new study describes a bioluminescent gene that could be the reason that so-called 'sea pickles,' or pyrosomes, an underwater free-floating colony of thousands of tiny animals, reverberate in blue-green light. If confirmed, the finding would be the first bioluminescent gene identified from a chordate--the group that includes all vertebrates as well as a couple types of invertebrates: sea squirts (including pyrosomes) and lancelets.
