Team discovers new paradigm for describing trophic cascades caused by infectious agents

When gray wolves were reintroduced to Yellowstone National Park, they sparked a resurgence of aspen trees.

Cow antibodies yield important clues for developing a broadly effective AIDS vaccine

(International AIDS Vaccine Initiative) As outlined in a study published today in Nature, lead author Devin Sok, Director, Antibody Discovery and Development at the International AIDS Vaccine Initiative (IAVI), reports the elicitation of powerful, HIV-blocking antibodies in cows in a matter of weeks - a process that usually takes years in humans.

Molting feathers may help birds deal with environmental contaminants

(Wiley) Mercury is a ubiquitous environmental contaminant that affects the health of birds and other wild animals.

Innate reaction of hematopoietic stem cells to severe infections

(University of Zurich) Researchers at the University of Zurich have shown for the first time that hematopoietic stem cells detect infectious agents themselves and begin to divide -- that is, without signals from growth factors. ThisShow More Summary

Library of CRISPR targeting sequences increases power of the gene-editing method

CRISPR, the gene-editing technology that has taken biology by storm, is now more powerful than ever. Scientists have assembled a library of RNA sequences that can be used by researchers to direct the CRISPR-cas9 complex to cut DNA with exquisite, unprecedented precision.

Elephant seals recognize each other by the rhythm of their calls

Every day, humans pick up on idiosyncrasies such as slow drawls, high-pitched squeaks, or hints of accents to put names to voices from afar. This ability may not be as unique as once thought, researchers report on July 20 in Current Biology. Show More Summary

Researchers in Cambodia find nest of rare riverine bird

Wildlife researchers in Cambodia say they have found a breeding location for the masked finfoot bird, one of the world's most endangered, raising hopes of its continuing survival.

Search and rescue dogs do their jobs despite travel stress

When disaster strikes, you want the very best tools, functioning at their peak. In the case of catastrophic earthquakes, tornadoes, or even bombings in war zones, those tools are search and rescue dogs. But researchers have found that getting dogs to disaster sites can add to the animals' stress.

Heritage and ancient grain project feeds a growing demand

After a century of markets dominated by a few types of wheat and white flour, ancient and heritage wheat varieties are making a comeback.

New mutations related to hereditary neuroendocrine tumours

(Centro Nacional de Investigaciones Oncológicas (CNIO)) The presence of a germline mutation in the GOT2 gene found in a patient with metastasis gives rise to increased activity of the encoder enzyme. Furthermore, the authors describe extraordinarily rare mutations in two patients: one in the SDHC gene and another in the IDH1. Show More Summary

Taste and health affect consumer choices for milk and nondairy beverages

(Elsevier) To learn more about what affects consumer decisions regarding fluid milk purchases, researchers from North Carolina State University used surveys, conjoint analysis, and means-end-chain analysis to uncover the underlying values among dairy milk and nondairy beverage consumers.

Mixed outcomes for plants and animals in warmer 2080s climate

(University of York) More than three quarters of plants and animals in England are likely to be significantly affected by climate change by the end of the century, say researchers.

The way rivers function reflects their ecological status and is rarely explored

(University of the Basque Country ) A study conducted by a UPV/EHU-University of the Basque Country research group within the framework of the European Globaqua project proposes going beyond the study of river ecosystems and incorporating...Show More Summary

Researchers improve method to identify aquatic species using environmental DNA

(University of Notre Dame) Researchers from the University of Notre Dame have improved their method of tracking species by using the biological material those organisms leave behind known as environmental DNA (eDNA).

Reintroduced Przewalski's horses have a different diet

The Przewalski's horse, also called Takhi or Mongolian wild horse, is the only remaining wild horse species. In 1969, wild horses were officially declared extinct. However, a few animals survived in captivity. In 1992, first captive bred wild horses were returned to the wild.

AI suggests recipe for a dish just by studying a photo of it

An algorithm trained on over one million online recipes can tell you what's in a dish and how to make it

Researchers improve method to identify aquatic species using environmental DNA

Determining which fish are living in various bodies of water can be a daunting task for scientists studying those populations. Identifying invasive or endangered species, for example, has often relied on the ability to catch them.

Lions and lambs—can you solve this classic game theory puzzle?

How many lions does it take to kill a lamb? The answer isn't as straightforward as you might think. Not, at least, according to game theory.

'Invasive' species have been around much longer than believed

The DST-NRF Centre of Excellence for Palaeoscience funded researchers based in the School of Geography, Archaeology and Environmental Studies and in the Evolutionary Studies Institute of the University of the Witwatersrand have used fossil pollen records to solve an ongoing debate regarding invasive plant species in eastern Lesotho.

Giant sunfish species eludes discovery for centuries

An elusive new species of ocean sunfish has been discovered by an international team of researchers led by a Murdoch University PhD student.
