Published Microalgae with unusual cell biology
(via sciencedaily.com) Original source A globally distributed single-celled organism that occurs in harmful algal blooms has been found to exhibit an unusual organisation of photosynthesis. Researchers have taken a closer look at the unusual cell biology of the species Prorocentrum cordatum from the group of dinoflagellates. The results of their study could help to better understand the role of the species in the environment and the increased occurrence of algal blooms at higher water temperatures.
Published Plant Lavender, Marjoram and Ivy on your green wall to clean up the air
(via sciencedaily.com) Original source Green walls can strip pollution from the air -- and some plants do it better than others, according to new research. Researchers planted 10 species on a custom-built 1.4m green wall.
Published An evolutionary mystery 125 million years in the making
(via sciencedaily.com) Original source Plant biologists have uncovered an evolutionary mystery over 100 million years in the making. It turns out that sometime during the last 125 million years, tomatoes and Arabidopsis thaliana plants experienced an extreme genetic makeover. Just what happened remains unclear. But the mystery surrounds CLV3, a gene key to healthy plant growth and development.
Published Shining a light on the effects of habituation and neural adaptation on the evolution of animal signals
(via sciencedaily.com) Original source A new paper examines the possible effects of two properties of receiver playing fields documented in studies of animal psychology -- habituation and neural adaptation -- on the efficacy of mate choice signals.
Published Effect of keratin microsphere gel on hair growth in mice
(via sciencedaily.com) Original source Keratin microsphere gel, consisting of keratin-based microspheres that swell in water to form a gel, has shown efficacy in promoting hair follicle growth in murine models. Its potential application as an active ingredient in hair regrowth treatments with minimal side effects is anticipated.
Published Genetic research revealed several new fern species in tropical America
(via sciencedaily.com) Original source Researchers have clarified the evolutionary history of a previously poorly known group of ferns from the tropical rainforests of America using DNA methods. The study discovered many new fern species, 18 of which have now been given official names and species descriptions.
Published A new plant's name that tells a story
(via sciencedaily.com) Original source A new species and genus of fairy lantern, tiny glass-like white plants that feed on fungi, has been discovered in Japan. In the country renowned for its extensive flora research, the discovery of a new plant genus is extremely rare and has not occurred in almost 100 years.
Published The Golgi organelle's ribbon structure is not exclusive to vertebrates, contrary to previous consensus
(via sciencedaily.com) Original source Researchers report that the Golgi ribbon, an organelle structure previously thought to be exclusive to vertebrates, is also present in animal taxa, including mollusks, earthworms, and sea urchins. The function of the Golgi ribbon is still enigmatic, but its presence in diverse animal lineages indicates that its function is not vertebrate specific, as previously thought. The team also showed Golgi ribbons form at a specific timepoint during embryogenesis, which suggests that they might play a role in cell differentiation.
Published Older African elephants will be most severely affected by the changing climate
(via sciencedaily.com) Original source Older elephants in East Africa will be most severely impacted by climate change, threatening the long-term survival of this vulnerable African mammal, according to a new study.
Published Avian influenza virus is adapting to spread to marine mammals
(via sciencedaily.com) Original source Avian influenza virus H5N1 has adapted to spread between birds and marine mammals, finds a new study.
Published Radio waves can tune up bacteria to become life-saving medicines
(via sciencedaily.com) Original source Scientists have found a new way to alter the DNA of bacterial cells -- a process used to make many vital medicines including insulin -- much more efficiently than standard industry techniques.
Published Counting rays: Aerial surveys reveal ample populations in Southeast Florida
(via sciencedaily.com) Original source A unique long-term study quantified the abundance of whitespotted eagle and giant manta rays in Southeast Florida. Researchers conducted 120 survey flights between 2014 and 2021 from Miami north to the Jupiter Inlet. One or both species were seen on nearly every flight and both populations appear to be stable in the region. The giant manta rays were more abundant in the south and the whitespotted eagle rays were found all along the coast. Neither species seems to be deterred by the greater human population density in Fort Lauderdale/Miami.
Published Double trouble at chromosome ends
(via sciencedaily.com) Original source New findings suggest the end-replication problem, an old standby of biology textbooks, is twice as intricate as once thought.
Published Change in gene code may explain how human ancestors lost tails
(via sciencedaily.com) Original source A genetic change in our ancient ancestors may partly explain why humans don't have tails like monkeys.
Published Extinctions could result as fish change foraging behavior in response to rising temperatures
(via sciencedaily.com) Original source Fish species respond to temperature increases by going after more readily available prey. Models suggest this behavior could lead to more extinctions.
Published Microbial comics: RNA as a common language, presented in extracellular speech-bubbles
(via sciencedaily.com) Original source Decoding the conversations between microbes of hypersaline environments reveals deep insights into the origins of complex life.
Published Human stem cells coaxed to mimic the very early central nervous system
(via sciencedaily.com) Original source The first stem cell culture method that produces a full model of the early stages of the human central nervous system has been developed by a team of engineers and biologists.
Published 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.
Published 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.
Published 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.
