A new conceptual framework for incorporating the way plants use carbon and water, or plant dynamics, into fine-scale computer models of wildland fire provides a critical first step toward improved global fire forecasting.

By working together, dolphins and net-casting fishers in Brazil each catch more fish, a rare example of an interaction by two top predators that is beneficial to both parties, researchers have concluded following 15 years of study of the practice.

A new biomaterial that can be injected intravenously, reduces inflammation in tissue and promotes cell and tissue repair. The biomaterial was tested and proven effective in treating tissue damage caused by heart attacks in both rodent and large animal models. Researchers also provided proof of concept in a rodent model that the biomaterial could be beneficial to patients with traumatic brain injury and pulmonary arterial hypertension.

A new study has uncovered a new thalattosuchian -- an ancient 'sister' of modern-day crocodiles' ancestors.

A new study has for the first time predicted which invasive species could pose a future threat to the UK's ecologically unique Overseas Territories.

The loss of pollinators, such as bees, is a huge challenge for global biodiversity and affects humanity by causing problems in food production. Researchers have now developed the first passively flying robot equipped with artificial muscle. Could this artificial fairy be utilized in pollination?

Scientists have created an AI system capable of generating artificial enzymes from scratch. In laboratory tests, some of these enzymes worked as well as those found in nature, even when their artificially generated amino acid sequences diverged significantly from any known natural protein.

What drives crocodile evolution? Is climate a major factor or changes in sea levels? Determined to find answers to these questions, researchers discovered that while changing temperatures and rainfall had little impact on the crocodiles' gene flow over the past three million years, changes to sea levels during the Ice Age had a different effect.

Humans retain an understanding of gestures made by other great apes, even though we no longer use them ourselves, according to a new study.

Federal environmental laws are failing to mitigate against Australia's extinction crisis, according to new research.

Seed dispersal is an essential process for the evolution and ecology of terrestrial plants, making discoveries of uncommon seed dispersal agents particularly interesting. Scientists now reveal that the Amami rabbit (Pentalagus furnessi) is a major seed dispersal agent for the non-photosynthetic plant Balanophora yuwanensis. To the best of our knowledge, this is the first known instance of rabbits serving as seed dispersal agents in Asia.

Protected natural areas of the UK are struggling to halt declines in insects and spiders that have occurred over the past 30 years, according to a new study.

The unique genetics of the Australian black swan leaves the species vulnerable to viral illnesses such as avian flu, new research has revealed.

A researcher has created a computer reconstruction of a virus, including its complete native genome. Although other researchers have created similar reconstructions, this is believed to be the first to replicate the exact chemical and 3D structure of a 'live' virus.

Varroa destructor is an ectoparasitic mite that can cause European honey bee colonies to collapse by spreading Deformed wing virus as they feed. A study suggests a relatively small number of mites can contribute to a large number of infected bees.

The discovery of more than 250 fossilized eggs reveals intimate details about the lives of titanosaurs in the Indian subcontinent, according to a new study.

Crocodiles were mummified in a unique way at the Egyptian site of Qubbat al-Hawa during the 5th Century BC, according to a new study.

Flooding in Australia's Murray-Darling Basin is creating ideal breeding conditions for many native species that have evolved to take advantage of temporary flood conditions. Scientists have now developed virtual models of the Murray River to reveal a crucial link between natural flooding and the extinction risk of endangered southern bell frogs (Litoria raniformis; also known as growling grass frogs). Southern bell frogs are one of Australia's 100 Priority Threatened Species. This endangered frog breeds during spring and summer when water levels increase in their wetlands. However, the natural flooding patterns in Australia's largest river system have been negatively impacted by expansive river regulation that in some years, sees up to 60% of river water extracted for human use.

Research into how echidnas might respond to a warming climate has found clever techniques used by the animal to cope with heat, including blowing bubbles to wet its nose tip, with the moisture then evaporating and cooling its blood.

Climate change presents a mismatch for some breeding songbirds, finds a new study using a decade of nestbox data.
