Researchers examine cooling power plants with brackish groundwater      (via sciencedaily.com)     Original source 

Nontraditional water sources can be deployed to help cope with climate-induced water risks and tackle the increasing water demand for decarbonization of fossil fuel-fired power plants, but that could increase the cost of electricity generation by 8 percent to 10 percent.

How a drought affects trees depends on what's been holding them back      (via sciencedaily.com)     Original source 

Droughts can be good for trees. Certain trees, that is. Contrary to expectation, sometimes a record-breaking drought can increase tree growth. Why and where this happens is the subject of a new article.

Identifying the bee's knees of bumble bee diets      (via sciencedaily.com)     Original source 

A new study has identified the bee's knees of bumble bee dietary options in Ohio and the Upper Midwest. By viewing almost 23,000 bumble bee-flower interactions over two years, researchers found that these bees don't always settle for the most abundant flowers in their foraging area -- suggesting they have more discerning dietary preferences than one might expect.

A guide through the genome      (via sciencedaily.com)     Original source 

Plants show enormous variety in traits relevant to breeding, such as plant height, yield and resistance to pests. One of the greatest challenges in modern plant research is to identify the differences in genetic information that are responsible for this variation.

How plants use sugar to produce roots      (via sciencedaily.com)     Original source 

Along with sugar reallocation, a basic molecular mechanism within plants controls the formation of new lateral roots. Botanists have demonstrated that it is based on the activity of a certain factor, the target of rapamycin (TOR) protein. A better understanding of the processes that regulate root branching at the molecular level could contribute to improving plant growth and therefore crop yields, according to the research team leader.

Demystifying vortex rings in nuclear fusion, supernovae      (via sciencedaily.com)     Original source 

Better understanding the formation of swirling, ring-shaped disturbances -- known as vortex rings -- could help nuclear fusion researchers compress fuel more efficiently, bringing it closer to becoming a viable energy source. A mathematical model linking these vortices with more pedestrian types, like smoke rings, could help engineers control their behavior in power generation and more.

Watch these cells rapidly create protrusions for exploration and movement      (via sciencedaily.com)     Original source 

In order to move, cells must be able to rapidly change shape. A team of researchers show that cells achieve this by storing extra 'skin' in folds and bumps on their surface. This cell surface excess can be rapidly deployed to cover temporary protrusions and then folded away for next time.

Study finds carrying pollen heats up bumble bees, raises new climate change questions      (via sciencedaily.com)     Original source 

A new study finds carrying pollen is a workout that significantly increases the body temperature of bumble bees. This new understanding of active bumble bee body temperatures raises questions about how these species will be impacted by a warmer world due to climate change.

Is it an ant? Is it a plant? No, it's a spider!      (via sciencedaily.com)     Original source 

A species of tiny, colorful jumping spider employs two lines of defense to avoid being eaten: camouflaging with plants and walking like an ant. Researchers report that this combination of camouflage and movement mimicry helps the spiders evade spider-eating spiders but does not deter hungry praying mantises.

'Improved' cookstoves emit more ultrafine particles than conventional stoves      (via sciencedaily.com)     Original source 

Improved cookstoves, which are widely used for cooking in developing countries, produce twice as many harmful ultrafine air pollution particles (PM0.1) as conventional stoves, according to a new study.

Like ancient mariners, ancestors of Prochlorococcus microbes rode out to sea on exoskeleton particles      (via sciencedaily.com)     Original source 

Throughout the ocean, billions upon billions of plant-like microbes make up an invisible floating forest. As they drift, the tiny organisms use sunlight to suck up carbon dioxide from the atmosphere. Collectively, these photosynthesizing plankton, or phytoplankton, absorb almost as much CO2 as the world’s terrestrial forests. A measurable fraction of their carbon-capturing muscle comes from Prochlorococcus — an emerald-tinged free-floater that is the most abundant phytoplankton in the oceans today. New research suggests the microbe's ancient coastal ancestors colonized the ocean by rafting out on chitin particles.

Unlocking the power of photosynthesis for clean energy production      (via sciencedaily.com)     Original source 

Researchers are embarking on a groundbreaking project to mimic the natural process of photosynthesis using bacteria to deliver electrons to a nanocrystal semiconductor photocatalyst. By leveraging the unique properties of microorganisms and nanomaterials, the system has the potential to replace current approaches that derive hydrogen from fossil fuels, revolutionizing the way hydrogen fuel is produced and unlocking a powerful source of renewable energy.

Crops evolved by swapping genetic modules between cells      (via sciencedaily.com)     Original source 

Comparing individual cells across corn, sorghum, and millet reveals evolutionary differences among these important cereal crops, according to a new study. The findings bring researchers closer to pinpointing which genes control important agricultural traits such as drought tolerance, which will help scientists faced with a changing climate adapt crops to drier environments.

Exploring the underground connections between trees      (via sciencedaily.com)     Original source 

Fungal networks interconnecting trees in a forest is a key factor that determines the nature of forests and their response to climate change. These networks have also been viewed as a means for trees to help their offspring and other tree-friends, according to the increasingly popular 'mother-tree hypothesis'. An international group of researchers re-examined the evidence for and against this hypothesis in a new study.

Researchers close to unleashing rapeseed's protein power for human consumption      (via sciencedaily.com)     Original source 

Half of plant proteins in the EU come from rapeseed plants. Until now, the plant has only been used for oil and animal feed, as it is both bitter and unsafe for human consumption. In a new study, researchers have gotten closer to removing the plant's bitter substances, and in doing so, are paving the way for a new protein source to support the green transition.

Biofortification of microgreens with zinc could mitigate global 'hidden hunger'      (via sciencedaily.com)     Original source 

When the seeds of plants such as pea and sunflower are biofortified with zinc, the seedlings they quickly produce -- harvested as microgreens -- could both help to mitigate global malnutrition and boost the odds of people surviving a catastrophe.
