Bioenergy crops are an alternative energy source that, unlike fossil fuels, could positively impact the environment by reducing greenhouse gases, soil erosion, and carbon dioxide levels. They can be produced even more sustainably if they are grown on poor quality land unsuitable for food. To make up for the poor land quality, these crops can rely on soil microbes like bacteria and fungi to help them access nutrients and water and store more carbon.

Amid calls for racial and social justice nationwide, businesses and educational institutions are grappling with how to adopt more inclusive organizational practices, including more diversified hiring. However, recruitment teams and strategic leaders often blame their lack of a diverse workforce on a lack of diverse applicants. A large study of recruitment data suggests a simple and efficient way of increasing diversity in applicant pools: have more diverse recruitment committees and leadership teams.

An unknown methane-producing process is likely at work in the hidden ocean beneath the icy shell of Saturn's moon Enceladus, suggests a new study published in Nature Astronomy by scientists at the University of Arizona and Paris Sciences & Lettres University.

The newly developed method lets researchers rapidly and accurately measure stress hormones in snow leopards without the need for bulky equipment or specialised knowledge. It uses widely available equipment that can be carried into the field, allowing hormone extraction from faecal samples and analysis to be done on site.

This differs from existing approaches to hormone monitoring in wild animals, where faecal samples must be taken to laboratories for hormone extraction and analysis. These approaches are particularly limiting in remote locations, such as the Himalayas.

Scientists at the University of Cambridge have identified rare genetic variants - carried by one in 3,000 people - that have a larger impact on the risk of developing type 2 diabetes than any previously identified genetic effect.

In the line-up of wild African fruits, the marula is the best known. For thousands of years, people have depended on the trees for food, medicines, and more. It is also exported globally as the rockstar ingredient of a cream liqueur. The fruit is a success story far beyond the savannas and bushveld where the trees grow.

But there is a whole choir of other wild, indigenous fruits in Southern Africa. And some exceed daily nutritional values recommended by the WHO and others.

Coastal communities across the world are increasingly facing up to the huge threats posed by a combination of extreme storms and predicted rises in sea levels as a result of global climate change.

However, scientists at the University of Plymouth have developed a simple algorithm-based model which accurately predicts how coastlines could be affected and - as a result - enables communities to identify the actions they might need to take in order to adapt.

A study published the week of July 5 in the Proceedings of the National Academy of Sciences led by Michael Moore at Washington University in St. Louis finds that dragonfly males have consistently evolved less breeding coloration in regions with hotter climates.

The surprising results of a decade-long investigation by Alessandro Vezzosi and Agnese Sabato provide a strong basis for advancing a project researching Leonardo da Vinci's DNA.

Researchers have devised a way to multiply by more than ten-fold the accessible details of gene activity in individual cells. It's a big leap in the effort to understand cancer development, brain function, immunity and other biological processes driven by the complex interactions of multitudes of different cell types.

A huge global network of researchers is working together to take the pulse of our global tropical forests.

ForestPlots.net, which is co-ordinated from the University of Leeds, brings together more than 2,500 scientists who have examined millions of trees to explore the effect of climate change on forests and biodiversity.

A new research paper published in Biological Conservation explains the origins of the network, and how the power of collaboration is transforming forest research in Africa, South America and Asia.

Neuroscientists at the University of Massachusetts Amherst have demonstrated in new research that dopamine plays a key role in how songbirds learn complex new sounds.

Published in the Journal of Neuroscience, the finding that dopamine drives plasticity in the auditory pallium of zebra finches lays new groundwork for advancing the understanding of the functions of this neurotransmitter in an area of the brain that encodes complex stimuli.

For decades, people have wondered why pelagic red crabs--also called tuna crabs--sometimes wash ashore in the millions on the West Coast of the United States. New research shows that atypical currents, rather than abnormal temperatures, likely bring them up from their home range off Baja California.

Alongside the discovery, the scientists also created a seawater flow index that could help researchers and managers detect abnormal current years.

A surprising study by UNSW on the behaviour of unrelated lizards in very different parts of the world has demonstrated how evolution can lead to different species learning the same skills.

The study in Ecology Letters documents how the Anolis lizard species in the Caribbean, and the Draco lizard species in Southeast Asia, have solved the challenge of communicating with one another to defend territories and attract mates.

In cancer research, it's a common goal to find something about cancer cells -- some sort of molecule -- that drives their ability to survive, and determine if that molecule could be inhibited with a drug, halting tumor growth. Even better: The molecule isn't present in healthy cells, so they remain untouched by the new therapy.
