Hermit crabs are essential scavengers in the ocean. They may crawl into discarded tires looking for food or shelter, and become trapped and die of starvation.

Discarded Tires Are 'Ghost Fishing' Hermit Crabs

New research suggests these shell-swapping crustaceans are vulnerable to becoming trapped inside human debris

But when severe drought and extreme heat collide, as they have this year, states like California that rely heavily on hydropower can be forced to buy extra power to meet demand, which tends to spike when temperatures soar.

Western Drought Drives Decline in Hydroelectric Power Generation

A new report predicts hydropower in the U.S. will fall by nearly 14 percent compared to last year

Facebook’s move comes as threats to the Brazilian Amazon from logging and land clearing only appear to be growing.

Olive sea snakes are among the largest marine snake species and sometimes make contact with divers.

Venomous Sea Snakes That Charge Divers May Just Be Looking for Love

A new study suggests apparent attacks are actually fleeting cases of mistaken identity

A fox squirrel perched on part of an experiment designed to test its agility and decision-making. Researchers used peanuts to entice the rodents to participate.

At least 40 arachnid species kill and eat certain slithering predators, which can be up to 30 times the eight-legged critters' size

Emperor penguins are the world's largest penguin, standing almost four feet tall and weighing around 88 pounds. They live almost exclusively in Antarctica and need sea ice to survive.

New Research

Climate Change Poised to Push Emperor Penguins to the Brink of Extinction

Study estimates 98 percent of colonies will be quasi-extinct by 2100 unless the world drastically reduces its greenhouse gas emissions

Poland's coal-fired Belchatow Power Station released 38 million tons of carbon dioxide into the atmosphere in 2018.

Targeting the world's worst emitters could offer disproportionate benefits when it comes to fighting climate change

An adult male transient or Bigg's killer whale.

Stranded Killer Whale Survives With the Help of Humans

The whale was spotted stuck among the rocks of an island in Southeast Alaska, but after about six hours on dry land the whale was able to swim off

A new article suggests that cats have been underutilized in studies of genetic disease and that studying their genomes, which are structured similarly to humans', could yield new treatments.

New Research

Human Genomes Are Surprisingly Cat-Like

Cat genomes are more similar to ours than those of mice and dogs, yet researchers say felines are underutilized in genetic studies of disease

This map shows how land and ocean temperatures have changed from June 2021 relative to the 1951-1980 base period. High values (darker red colors) indicate temperatures that are higher than those in the base period. The number in the top right is an estimate of the global mean temperature increase. All temperatures are in Celsius.

Study Measuring Earth's Vital Signs Warns of Climate Tipping Points

The authors say tropical coral reefs, the Amazon rainforest, and the West Antarctic and Greenland ice sheets may have passed dangerous tipping points
