An elegant new orchid hiding in plain sight      (via sciencedaily.com) 

It is extremely rare for a new plant species to be discovered in Japan, a nation where flora has been extensively studied and documented. Nevertheless, botanists recently uncovered a stunning new species of orchid whose rosy pink petals bear a striking resemblance to glasswork. Interestingly, it can be found in familiar environments such as lawns and parks, and even in private gardens and on balconies. This research suggests that other new species may be hiding in common places.

Breakthrough in the understanding of quantum turbulence      (via sciencedaily.com) 

Researchers have shown how energy disappears in quantum turbulence, paving the way for a better understanding of turbulence in scales ranging from the microscopic to the planetary. The team's findings demonstrate a new understanding of how wave-like motion transfers energy from macroscopic to microscopic length scales, and their results confirm a theoretical prediction about how the energy is dissipated at small scales. In the future, an improved understanding of turbulence beginning on the quantum level could allow for improved engineering in domains where the flow and behavior of fluids and gases like water and air is a key question. Understanding that in classical fluids will help scientists do things like improve the aerodynamics of vehicles, predict the weather with better accuracy, or control water flow in pipes. There is a huge number of potential real-world uses for understanding macroscopic turbulence.

Compressive stress shapes the symmetry of Arabidopsis root vascular tissue      (via sciencedaily.com) 

A cytokinin-mediated, proliferation-based mechanism is involved in the generation and maintenance of cell-type specific tissue boundaries during vascular development in Arabidopsis roots. Specifically, the HANABA-TARANU transcription factor forms a feed-forward loop to cytokinin signaling, which in turn regulates the position and frequency of cell proliferation of proto-vascular cells such that mechanical stress of the surrounding tissues guides growth in an apical-oriented manor, maintaining cell patterning throughout the tissue section.

Modelling superfast processes in organic solar cell material      (via sciencedaily.com) 

In organic solar cells, carbon-based polymers convert light into charges that are passed to an acceptor. Scientists have now calculated how this happens by combining molecular dynamics simulations with quantum calculations and have provided theoretical insights to interpret experimental data.

Bigger flowers, greater rewards: Plants adapt to climate disruptions to lure pollinators      (via sciencedaily.com) 

There's been a well-documented shift toward earlier springtime flowering in many plants as the world warms. The trend alarms biologists because it has the potential to disrupt carefully choreographed interactions between plants and the creatures -- butterflies, bees, birds, bats and others -- that pollinate them.

Microneedle-based drug delivery technique for plants      (via sciencedaily.com) 

The agriculture industry is under pressure to adopt sustainable and precise agricultural practices that enable more efficient use of resources due to worsening environmental conditions resulting from climate change, an ever-expanding human population, limited resources, and a shortage of arable land. As a result, developing delivery systems that efficiently distribute micronutrients, pesticides, and antibiotics in crops is crucial to ensuring high productivity and high-quality produce while minimising resource waste. However, current and standard practices for agrochemical application in plants are inefficient. These practices cause significant detrimental environmental side effects, such as water and soil contamination, biodiversity loss and degraded ecosystems; and public health concerns, such as respiratory problems, chemical exposure and food contamination.

TurboID uncovers new meiotic proteins in Arabidopsis thaliana      (via sciencedaily.com) 

Meiotic recombination assures genetic variation during breeding. During meiotic prophase I, chromosomes are organized in a loop-base array by a proteinaceous structure called meiotic chromosome axis which is critical for meiotic recombination and genetically diverse gametes. An international research team reports the application of a TurboID (TbID)-based approach to identify proteins in proximity of meiotic chromosome axes in Arabidopsis thaliana. Not only known but also new meiotic proteins were uncovered.

In the world's smallest ball game, scientists throw and catch single atoms using light      (via sciencedaily.com) 

Researchers show that individual atoms can be caught and thrown using light. This is the first time an atom has been released from a trap -- or thrown -- and then caught by another trap. This technology could be used in quantum computing applications.

Hitting nuclei with light may create fluid primordial matter      (via sciencedaily.com) 

A new analysis supports the idea that photons colliding with heavy ions create a fluid of 'strongly interacting' particles. The results indicate that photon-heavy ion collisions can create a strongly interacting fluid that responds to the initial collision geometry and that these collisions can form a quark-gluon plasma. These findings will help guide future experiments at the planned Electron-Ion Collider.

Plant roots fuel tropical soil animal communities      (via sciencedaily.com) 

A research team has shed new light on the importance of plant roots for below-ground life, particularly in the tropics. Millions of small creatures toiling in a single hectare of soil including earthworms, springtails, mites, insects, and other arthropods are crucial for decomposition and soil health. For a long time, it was believed that leaf litter is the primary resource for these animals. However, this recent study is the first to provide proof that resources derived from plant roots drive soil animal communities in the tropics.

An internal thermometer tells the seeds when to germinate      (via sciencedaily.com) 

Germination is a crucial stage in the life of a plant as it will leave the stage of seed resistant to various environmental constraints (climatic conditions, absence of nutritive elements, etc.) to become a seedling much more vulnerable. The survival of the young plant depends on the timing of this transition. It is therefore essential that this stage be finely controlled. Botanists have now discovered the internal thermometer of seeds that can delay or even block germination if temperatures are too high for the future seedling. This work could help optimize plant growth in a context of global warming.
