Researchers have created a reusable hydrogel that releases artificial saliva over time, which could help provide sustained relief from dry mouth.

Researchers have come up with a new way to fortify foods and beverages with iron or iodine, using small crystalline particles. The particles could be sprinkled onto meals, added to staple foods such as bread, or mixed into drinks.

Researchers developed an organic "filter" material that is effective in trapping nitrate, arsenic and uranium from water. The material remains effective even in very cold climates.

The database was developed to help target conservation efforts across Australia’s 9,300 islands using information from multiple sources, including the Atlas of Living Australia platform and thousands of published wildlife survey.

When a North American river otter left behind some weird looking poo on a dock in Maryland and got caught by a wildlife camera, scientists started to investigate.

Despite being one of the most abundant herbivores in the Arctic, climate change has contributed to a loss of nearly two-thirds of the reindeers' global abundance over the last three decades.

Using fiber optic technology, an international research team was able to measure for the first time that the impact of the breaking-off chunks of ice into the sea and their subsequent drifting away increases mixing with the warm water in the depths.

Advances in artificial intelligence for porous materials design could impact a wide variety of fields, from orthopedic implants to next-generation batteries.

The team sought to determine whether regions of the eyes and nose had higher temperature outputs, and if they exhibited consistent temperature change.

The most common whale-dolphin interaction involved dolphins swimming near the whale’s rostrum, akin to bow riding, which could indicate an energy-efficient mode of locomotion and a form of one-sided play by dolphins.
