To ensure that plants flower at the right time of year, they possess an internal clock, which enables them to measure the amount of daylight during a day. Biologists now describe that the mutation of a specific gene makes the flowering time of barley almost entirely independent of day length. This mutation can be useful for breeding varieties adapted to altered climatic conditions with relatively mild winters and hot, dry summers.

The tendency of communities and the species within them to become more similar or more distinct across landscapes -- biotic homogenization and differentiation -- are approximately balanced, according to a new study. This analysis is the first of its kind to provide a comprehensive assessment of how local and regional biodiversity changes combine across landscapes over centuries.

A new study shows that UK solar parks, if managed correctly, can provide vital resources to help stem the decline in the nation's bees and butterflies. The new research provides peer-reviewed field data of insect pollinators at solar parks in the UK, covering 15 sites.

Using a single photograph, researchers created an algorithm that computes highly accurate, full-color three-dimensional reconstructions of areas behind obstacles -- a concept that can not only help prevent car crashes, but help law enforcement experts in hostage situations, search-and-rescue and strategic military efforts.

Research shows the relationship between a species' age and its risk of going extinct could be accurately predicted by an ecological model called the 'neutral theory of biodiversity.'

Knowledge from local communities has resulted in the first-ever nesting evidence and discovery of a breeding population of an incredibly rare turtle in India.

In a group of plants that is famous for luring its pollinators into a death trap, one species offers its flowers as a nursery in exchange. The discovery blurs the line between mutualism and parasitism and sheds light on the evolution of complex plant-insect interactions.

Engineers have developed a new chip that uses light waves, rather than electricity, to perform the complex math essential to training AI. The chip has the potential to radically accelerate the processing speed of computers while also reducing their energy consumption.

Making quantum systems more scalable is one of the key requirements for the further development of quantum computers because the advantages they offer become increasingly evident as the systems are scaled up. Researchers have recently taken a decisive step towards achieving this goal.

When the female gametes in plants become fertilized, a signal from the sperm activates cell division, leading to the formation of new plant seeds. This activation can also be deliberately triggered without fertilization, as researchers have shown. Their findings open up new avenues for the asexual propagation of crop plants.

You'd think the complex flavor in a quality cup of tea would depend mainly on the tea varieties used to make it. But a new study shows that the making of a delicious cup of tea depends on another key ingredient: the collection of microbes found on tea roots. By altering that assemblage, the authors showed that they could make good-quality tea even better.

Researchers have identified significant differences between the diversity of gut bacteria in grey squirrels compared to red squirrels which could hold the key to further understanding the ability of grey squirrels to outcompete red squirrels in the UK.

Scientists have determined how the well-known plant hormone ethylene is crucial in controlling the angle at which roots grow. The findings can be used to engineer plants and crops that withstand the environmental stresses of climate change and drought, and perhaps to create plants that remove carbon dioxide from the atmosphere and store it deep underground to help mitigate climate change.

Australian birds that live on islands are among the species most at risk of extinction, a first-of-its-kind study has shown. Australia has over 750 native bird species. But many of them are facing an uncertain future.
