Measuring the properties of light: Scientists realize new method for determining quantum states      (via sciencedaily.com)     Original source 

Scientists have used a new method to determine the characteristics of optical, i.e. light-based, quantum states. For the first time, they are using certain photon detectors -- devices that can detect individual light particles -- for so-called homodyne detection. The ability to characterize optical quantum states makes the method an essential tool for quantum information processing.

Common plant could help reduce food insecurity      (via sciencedaily.com)     Original source 

An often-overlooked water plant that can double its biomass in two days, capture nitrogen from the air -- making it a valuable green fertilizer -- and be fed to poultry and livestock could serve as life-saving food for humans in the event of a catastrophe or disaster, a new study suggests.

Biomolecular condensates -- regulatory hubs for plant iron supply      (via sciencedaily.com)     Original source 

Iron is a micronutrient for plants. Biologists now show that regulatory proteins for iron uptake behave particularly dynamically in the cell nucleus when the cells are exposed to blue light -- an important signal for plant growth. They found that the initially homogeneously distributed proteins relocated together into 'biomolecular condensates' in the cell nucleus shortly after this exposure.

Altering the circadian clock adapts barley to short growing seasons      (via sciencedaily.com)     Original source 

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.

Photon upconversion: Steering light with supercritical coupling      (via sciencedaily.com)     Original source 

Researchers have unveiled a novel concept termed 'supercritical coupling' that enables several folds increase in photon upconversion efficiency. This discovery not only challenges existing paradigms, but also opens a new direction in the control of light emission.

Increasingly similar or different? Centuries-long analysis suggests biodiversity is differentiating and homogenizing to a comparable extent      (via sciencedaily.com)     Original source 

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.

New evidence shows UK solar parks can provide for bees and butterflies      (via sciencedaily.com)     Original source 

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.

Pollinator's death trap turns into nursery      (via sciencedaily.com)     Original source 

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.

Asexual propagation of crop plants gets closer      (via sciencedaily.com)     Original source 

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.

Root microbes may be the secret to a better tasting cup of tea      (via sciencedaily.com)     Original source 

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.
