How does the autophagic pathway regulate low-nitrogen tolerance in tomato?
Nitrogen (N) deficiency first affects the N uptake and assimilation systems of plants. Nitrate, the main source of plant N, is absorbed and transported by nitrate transporters. Nitrate can be metabolized directly in the roots after absorption and sto.....»»

Researchers discover new microRNA-regulated pathway to boost iPS cell-derived platelet production
A team of researchers led by Professor Koji Eto (Department of Clinical Application) recently discovered the importance of a microRNA-based regulatory mechanism for enhancing the quality and quantity of platelets generated by iPS cell-derived megakar.....»»
Scientists discover methods to regulate carbon storage in humus layer of forest in north China
It is estimated that 30% of the world's terrestrial carbon stocks are found in the boreal forest, 60% of which is below ground. Organic soil horizons contain about one-third of the soil carbon. Therefore, the stability of boreal soils is critical to.....»»
How flowers maintain water balance across different angiosperm branches
Flowers play an essential role in maintaining a species' genetic stability. Understanding how flowers regulate water use strategies to adapt to their environment is crucial for better understanding floral evolution and plant-pollinator-environment in.....»»
Core-shell structural units show outstanding toughening effect for ceramics

Scientists develop catalyst designed to make ammonia production more sustainable
Ammonia is one of the most widely produced chemicals in the world, and is used in a great many manufacturing and service industries. The conventional production technology is the Haber-Bosch process, which combines nitrogen gas (N2) and hydrogen gas.....»»
A holistic approach is key to improving drought adaptation in crops, researchers say
More focus on integrating research into drought tolerance in crops is essential to prevent the threat to global food security, according to international researchers......»»
Research team establishes synthetic dimension dynamics to manipulate light
In the realm of physics, synthetic dimensions (SDs) have emerged as one of the frontiers of active research, offering a pathway to explore phenomena in higher-dimensional spaces, beyond our conventional 3D geometrical space. The concept has garnered.....»»
Electronic perturbation-promoted interfacial pathway for facile C–H dissociation
Pt-based catalysts have been extensively employed in catalytic propane dehydrogenation (PDH) processes, playing a crucial role in propylene production. However, monometallic Pt catalysts often exhibit inferior propylene selectivity due to the hydroge.....»»
Pesticide-free as a new pathway for agriculture
A new approach is gaining momentum in European agriculture: a "third way" that lies between conventional production and organic farming systems. Here farmers must forego synthetic pesticides only—which is simpler to implement than a switch to organ.....»»
Researchers find new ways to regulate hole transport layer for efficient perovskite solar cells
According to a study published in Nano Energy, a research group led by Prof. Chen Chong from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has increased the photoelectric conversion efficiency (PCE) of perovskite solar c.....»»
Gene expression technology set to semi-automation
The Human Genome Project generated the first sequence of the human genome, revealing a kind of blueprint of human biology. Two decades later, the field of gene regulatory networks describes a complex system where thousands of genes regulate one anoth.....»»
Scientists find that micronuclei are not the primary trigger of the cGAS/STING pathway
Cells possess an innate immune system that defends against invasive pathogens such as bacteria and viruses. Previous studies have mapped out the cytoplasmic cGAS-STING pathway in the cytoplasm, known for responding to foreign nucleic acids, such as d.....»»
Root phenotyping research: Automated total root length estimation from in situ images without segmentation
Climate change stresses severely limit crop yields, with root traits playing a vital role in stress tolerance, thus highlighting the importance of root phenotyping for crop improvement. Recent advances in image-based root phenotyping, particularly th.....»»
How cells in developing embryos change the way they use enhancers to regulate gene expression
If you look at a nerve cell, a muscle cell, or a skin cell under the microscope, they appear strikingly different. However, every cell in our body has the same DNA and has descended from a common ancestor—the fertilized egg cell. The diversity we o.....»»
Saturn"s moon is a testing ground to gain a better understanding of the methane molecule
Titan is the second-largest moon in the solar system and the only one with a dense atmosphere. At the top of this atmosphere, rich in nitrogen and methane, the sun's radiation produces a great diversity of organic molecules, some of which we also fin.....»»
