The Colorado River is in an extremely severe drought and has been for the last 22 years. To better understand this drought, researchers looked at the drought history within the Colorado River Basin. Previous studies have gone back 1,200 years, but this paper goes back 2,000 years. The findings, using...
Development of a user-friendly, hot-melt, wound-healing adhesive
Scientist have developed a hot-melt tissue adhesive (i.e., medical glue that is applied in a molten state) capable of healing operative wounds. This adhesive has excellent medical material properties in terms of its ease of use, adhesiveness to tissues, biocompatibility and ability to prevent postoperative complications.
Europe’s largest land predator unearthed on the Isle of Wight
Palaeontologists have identified the remains of one of Europe's largest ever land-based hunters: a dinosaur that measured over 10m long and lived around 125 million years ago.
The secret lives of Darwin’s finches reveal daily commutes the equivalent of 30 soccer fields
Using radio transmitters, scientists have gained new insights into the behavior of medium ground finches in the Galapagos Islands. A study reveals daily movement patterns covering an area equivalent to the size of 30 soccer fields.
Bizarre meat-eating dinosaur joins ‘Rogues’ Gallery’ of giant predators from classic fossil site in Egypt’s Sahara Desert
The fossil of a still-unnamed species provides the first known record of the abelisaurid group of theropods from a middle Cretaceous-aged (approximately 98 million years old) rock unit known as the Bahariya Formation, which is exposed in the Bahariya Oasis of the Western Desert of Egypt.
Amazon River freshwater fish show signs of overexploitation
As the cherished rainforest in South America's Amazon River region continues to shrink, the river itself now presents evidence of other dangers: the overexploitation of freshwater fish.
Climate change and human exploitation to blame for historic decline in Atlantic Salmon
Research has revealed that an abrupt change in climate conditions in the North Atlantic around 800 years ago played a role in a decline in Atlantic salmon populations returning to rivers. Subsequent human exploitation of salmon combined to reduce their populations still further.
Updating our understanding of Earth’s architecture
New models that show how the continents were assembled are providing fresh insights into the history of the Earth and will help provide a better understanding of natural hazards like earthquakes and volcanoes.
Otters learn from each other — but solve some puzzles alone
Otters learn skills from each other -- but they also solve some mysteries alone, new research shows.
Tiny conservation heroes: Wild cherry blossoms could save forest landscapes
Researchers have found that symbolic species could be used for the conservation and community-based management of traditional forest landscapes. The team studied how different social groups within a local community valued wild cherry trees, a symbolic species important for connecting people with nature in Japan. The results indicated that differences...
