Two recent scientific studies provide new insights into Earth's climate dynamics, with a particular focus on the El Niño phenomenon. The results show how El Niño responds to natural factors over extended periods, while highlighting the increasing role of human activities in shaping this climatic phenomenon in the modern era.

The effects of extreme temperatures on avian reproduction can vary depending on the type of environment that birds call home. A new study found that extreme high temperatures significantly diminish bird reproductive success in agricultural landscapes.

Scientists have discovered the deepest known evidence of coral reef bleaching, more than 90 metres below the surface of the Indian Ocean. Identified during a research cruise, the damage to the deeper reefs in the Central Indian Ocean has been attributed to significant changes in the region's ocean temperature caused by the Indian Ocean Dipole. The researchers have also warned such incidences are only likely to increase as a result of present and future climate change.

Many people have experienced a muddy off-flavor in farmed fish. While the aquaculture industry has known about the problem for 20 years, it continues to impact the consumption of otherwise healthy and potentially sustainable fish. Now, researchers have been able to pinpoint exactly when the off-flavors emerge. And this can make it easier to deal with the compounds that turn people away from farmed fish.

Biodegradable plastics may not be the solution to plastic pollution many hoped for, with a new study showing they are still harmful to fish.

Whaling in the 20th century destroyed 99% of the Eastern North Pacific fin whale breeding population. Because there is enough genetic diversity, current conservation measures should help the population rebound without becoming inbred. The future of fin whales in the Gulf of California depends on the recovery of the Eastern North Pacific population.

Researchers say mapping the genetic code of the brushtail possum will benefit those working to both conserve and control the animal.

Scientists measured microplastic concentrations in the highly productive Barents Sea and suggest that ocean circulation, ice melt, tourism, inadequate waste management, shipping and fishing are all likely contributors.

Animal sounds are a very good indicator of biodiversity in tropical reforestation areas. Researchers demonstrate this by using sound recordings and AI models.

In the world of threatened and endangered species conservation, the genomic revolution has raised some complicated questions: How can scientists justify assessing species genetic diversity without consulting entire genomes now that they can be sequenced? But then again, how can scientists justify the time and expense of genome sequencing when age-old measures of neutral genetic diversity are much cheaper and easier to obtain? A new study suggests making a transition from 'old school' genetics to 'new school' genomics for species conservation purposes probably isn't necessary in all cases.

Researchers have discovered how the fungus Candida albicans enters the brain, activates two separate mechanisms in brain cells that promote its clearance, and, important for the understanding of Alzheimer's disease development, generates amyloid beta (Ab)-like peptides, toxic protein fragments from the amyloid precursor protein that are considered to be at the center of the development of Alzheimer's disease.

Surface ice in Greenland has been melting at an increasing rate in recent decades, while the trend in Antarctica has moved in the opposite direction, according to researchers.

When Hurricane Ian struck southwest Florida in September 2022, it unleashed a variety of Vibrio bacteria that can cause illness and death in humans, according to a new study.
