Published Pollination by more than one bee species improves cherry harvest
(via sciencedaily.com) Original source To obtain the biggest cherry harvest, trees should be pollinated by both honey bees and mason bees. This new study shows yet another benefit of biodiversity.
Published Lack of maternal care affects development, microbiome and health of wild bees
(via sciencedaily.com) Original source Most wild bees are solitary, but one tiny species of carpenter bees fastidiously cares for and raises their offspring, an act that translates into huge benefits to the developing bee's microbiome, development and health, found researchers. Without maternal care the pathogen load of these developing bees ballooned -- 85 per cent of were fungi, while eight per cent were bacteria -- which can impact their microbiome, a critical component of bee health, as well as their development, immune system and gene expression.
Published Researchers make strides in harnessing low-grade heat for efficient energy conversion
(via sciencedaily.com) A research team has achieved significant breakthroughs in harnessing low-grade heat sources (<100 °C) for efficient energy conversion.
Published Breakthrough: Highly efficient electrocatalyst for clean energy
(via sciencedaily.com) A research team has achieved a groundbreaking advancement in nanomaterials by successfully developing a highly efficient electrocatalyst which can enhance the generation of hydrogen significantly through electrochemical water splitting. This major breakthrough has great application potential for the clean energy industry.
Published Some spiders can transfer mercury contamination to land animals
(via sciencedaily.com) Sitting calmly in their webs, many spiders wait for prey to come to them. Arachnids along lakes and rivers eat aquatic insects, such as dragonflies. But, when these insects live in mercury-contaminated waterways, they can pass the metal along to the spiders that feed on them. Now, researchers have demonstrated how some shoreline spiders can move mercury contamination from riverbeds up the food chain to land animals.
Published Ohio's droughts are worse than often recognized, study finds
(via sciencedaily.com) Original source A new type of analysis suggests that droughts in Ohio were more severe from 2000 to 2019 than standard measurements have suggested.
Published More Texas owls are testing positive for rat poisons
(via sciencedaily.com) New research suggests that owls in Texas have high rates of anticoagulant rodenticides (AR) -- blood thinning rat poisons -- in their systems.
Published 100-year floods could occur yearly by end of 21st century
(via sciencedaily.com) Original source Most coastal communities will encounter '100-year floods' annually by the end of the century, even under a moderate scenario where carbon dioxide emissions peak by 2040, according to a new study. And as early as 2050, regions worldwide could experience 100-year floods every nine to fifteen years on average.
Published New research reveals why and when the Sahara Desert was green
(via sciencedaily.com) Original source A pioneering study has shed new light on North African humid periods that have occurred over the past 800,000 years and explains why the Sahara Desert was periodically green.
Published Freshwater connectivity can transport environmental DNA through the landscape
(via sciencedaily.com) A new article uses environmental DNA (eDNA) metabarcoding to analyze fish and zooplankton communities. The study found that the movement of water between freshwater bodies, or freshwater connectivity, can transport eDNA. This highlights the potential of eDNA to provide a comprehensive view of freshwater biodiversity.
Published New rivers in the North? Scientists identify how the dissection of Arctic landscapes is changing with accelerating climate change
(via sciencedaily.com) Original source New research shows that amplified global warming in the Canadian High Arctic drove a profound shift in the structure of a river network carved into a permafrost landscape in only 60 years.
Published Movement sensors can detect disease in wild boar
(via sciencedaily.com) Original source Accelerometers reading the behavior of wild boars can pick up when animals are infected with a fatal virus.
Published New super-fast flood model has potentially life-saving benefits
(via sciencedaily.com) Researchers have developed a new simulation model, which can predict flooding during an ongoing disaster more quickly and accurately than currently possible.
Published Climate change is reducing global river water quality
(via sciencedaily.com) Original source A review of almost 1000 studies on the effects of climate change and extreme weather events on rivers around the world has found an overall negative effect on water quality in rivers globally. An international team of experts sourced from every continent, conducted between 2000-2022.
Published Unlocking the genetic code of peppers: New study reveals insights into domestication and diversity
(via sciencedaily.com) Original source Peppers are a versatile, flavorful, and widely popular crop, used not only as a healthy food source but also for their medicinal properties. Scientists have now sequenced the genomes of key cultivated and wild pepper species, offering unprecedented insights into pepper evolution, domestication, and genetic diversity.
Published Fewer but more intense tropical storms predicted over the Ganges and Mekong
(via sciencedaily.com) Original source Climate experts project a decline in the frequency of future tropical storms but an increase in their strength across the Ganges and Mekong basins allowing for better future planning.
Published Fall snow levels can predict a season's total snowpack in some western states
(via sciencedaily.com) Original source Research found that, in some western states, the amount of snow already on the ground by the end of December is a good predictor of how much total snow that area will get.
Published Hot summer air turns into drinking water with new gel device
(via sciencedaily.com) Researchers have focused on the moisture present in the air as a potential source of drinking water for drought-stressed populations. They reached a significant breakthrough in their efforts to create drinkable water out of thin air: a molecularly engineered hydrogel that can create clean water using just the energy from sunlight.
Published You say tomato, these scientists say evolutionary mystery
(via sciencedaily.com) Original source Biologists have found evidence for evolutionary 'syndromes'-- sets of traits that occur together -- that help to explain how tomatoes first evolved their distinctive blend of color, sweetness, acidity and aroma. The research not only shines a light on how fruits evolve in the wild, but will also be valuable to crop-improvement efforts aimed at breeding more nutritious and appealing varieties of fruits.
Published Super antifreeze in cells: The ability to survive in ice and snow developed in animals far earlier than we thought
(via sciencedaily.com) Original source More than 400 million years ago, an insect-like animal called the springtail developed a small protein that prevents its cells from freezing.
