Asparagus and orchids are more similar than you think      (via sciencedaily.com)     Original source 

How is a beech leaf constructed? What determines the appearance of an asparagus? A new 'encyclopaedia' helps us learn more about the building blocks of plants. The encyclopaedia, probably the largest of its kind, could be used to improve targeted plant breeding efforts, to make them both more climate-resilient and more easily digestible.

Endangered seabird shows surprising individual flexibility to adapt to climate change      (via sciencedaily.com)     Original source 

New research finds that individual behavioural flexibility and not evolutionary selection is driving the northward shift of Balearic shearwaters. The findings were revealed through a decade-long study which tagged individual birds. The results indicate that individual animals may have greater behavioural flexibility to respond to climate change impacts than previously thought.

Back from the dead: Tropical tree fern repurposes its dead leaves      (via sciencedaily.com)     Original source 

Plant biologists report that a species of tree fern found only in Panama reanimates its own dead leaf fronds, converting them into root structures that feed the mother plant. The fern, Cyathea rojasiana, reconfigures these 'zombie leaves,' reversing the flow of water to draw nutrients back into the plant.

Scientists develop novel method to estimate biodiversity loss in Singapore over the past two centuries      (via sciencedaily.com)     Original source 

Scientists have employed novel statistical methods to reveal the extent of biodiversity loss in Singapore over the past two centuries. The study paints the most accurate picture to date of the ecological impact of deforestation and urban development in the tropical city-state. From a comprehensive dataset, the study estimated that Singapore has lost 37 per cent of its species.

World's first successful embryo transfer in rhinos paves the way for saving the northern white rhinos from extinction      (via sciencedaily.com)     Original source 

Scientists have succeeded in achieving the world's first pregnancy of a rhinoceros after an embryo transfer. The southern white rhino embryo was produced in vitro from collected egg cells and sperm and transferred into a southern white rhino surrogate mother at the Ol Pejeta Conservancy in Kenya on September 24, 2023. The BioRescue team confirmed a pregnancy of 70 days with a well-developed 6.4 cm long male embryo. The successful embryo transfer and pregnancy are a proof of concept and allow to now safely move to the transfer of northern white rhino embryos -- a cornerstone in the mission to save the northern white rhino from extinction.

Sparrows uniquely adapted to Bay Area marshes are losing their uniqueness      (via sciencedaily.com)     Original source 

How does loss of habitat affect the animals still living there? A genetic study of saltwater-adapted Savannah sparrows around the San Francisco Bay Area shows that the 90% loss of tidal marsh habitat has led to more interbreeding with freshwater-adapted Savannah sparrows, diminishing their genetic adaptation to saltwater, such as enlarged kidneys and larger beak. This could lessen their ability to live in a saltwater habitat.

Ancient brown bear genomes sheds light on Ice Age losses and survival      (via sciencedaily.com)     Original source 

The brown bear is one of the largest living terrestrial carnivores, and is widely distributed across the Northern Hemisphere. Unlike many other large carnivores that went extinct at the end of the last Ice Age (cave bear, sabretoothed cats, cave hyena), the brown bear is one of the lucky survivors that made it through to the present. The question has puzzled biologists for close to a century -- how was this so?

New study unveils how plants control the production of reactive oxygen species      (via sciencedaily.com)     Original source 

Reactive oxygen species (ROS), though generally regarded as toxic byproducts of biological processes, serve many important functions in plants. However, the precise mechanism that plants use to regulate the production of ROS remains elusive. In a recent study, researchers clarified how an important ROS-generating enzyme is activated, revealing mechanisms likely conserved across all land plants. Their findings could pave the way for breakthroughs in agricultural and environmental remediation tools.

Gravity helps show strong force strength in the proton      (via sciencedaily.com)     Original source 

New research conducted by nuclear physicists is using a method that connects theories of gravitation to interactions among the smallest particles of matter. The result is insight into the strong force, a powerful mediator of particle interactions in the subatomic realm. The research has revealed, for the first time, a snapshot of the distribution of the shear strength of the strong force inside the proton -- or how strong an effort must be to overcome the strong force to move an object it holds in its grasp. At its peak, the nuclear physicists found that a force of over four metric tons would be required to overcome the binding power of the strong force.
