The pace of glacier melting has sped up over the last two decades, according to an analysis of hundreds of thousands of glaciers that researchers called the most accurate of its kind.

Air pollution from wildfires could worsen eczema and itchy skin, according to the first study to examine the link between wildfire smoke on skin disease.

An analysis of butterflies in Switzerland found elevated nitrogen levels were linked with reduced species diversity and fewer individuals, suggesting that excess nitrogen could be an underestimated driver of insect declines.

A commonly used biodegradable plastic generated more tiny plastic fragments than a comparable conventional polymer, according to a lab-based pilot study that suggests compostable alternatives may not be as environmentally friendly as they seem.

Researchers used medical imaging techniques to peer inside a deep-sea octopus, allowing them to describe a new species without destroying the unique specimen.

A long-term study of baboons found that high levels of stress hormones were strongly linked with shorter lifespan, providing the first evidence that stress influences the survival of wild animals.

A new type of plastic that can be recycled over and over again has the potential to help reduce the staggering amount of plastic waste that is crammed into landfills and pollutes the environment, but researchers recommend tweaking production processes to make the material cheaper and more environmentally friendly.

Transmasculine people’s blood pressure increased after starting hormone therapy, while the opposite trend was seen in transfeminine participants, according to the largest and longest study of its kind.

Researchers have developed a compound that blocked an important regulator of heart failure in mice, which could pave the way toward future therapeutics for the often fatal condition.

CRISPR caused unintended changes to the genetic code in 16% of human embryo cells in a new study, and its authors say the findings highlight that more research is needed before the gene-editing tool is safe for human fertility applications.

A new test that detected lung cancer from exhaled breath with 96% accuracy is simpler and faster than similar breath tests, according to researchers, who suggest their advance is a step toward improved diagnostics for the prevalent disease.

A new study argues that just 2.8% of Earth's terrestrial area is "ecologically intact," about 10 times lower than previous estimates, which scientists use to help prioritize areas for conservation.
