Boron deficiency in oilseed rape transcriptome resembles a wounding and infection response
Boron deficiency has a devastating effect on oilseed rape and related plants. However, little is known about the underlying genetic mechanisms. A study shows that the response to persistent or short-term acute boron deficiency is similar to that seen.....»»
Researchers discover previously unknown gene that indirectly promotes photosynthesis in blue-green algae
Cyanobacteria—also called blue-green algae—are known as the "plants of the ocean" because they carry out photosynthesis on a gigantic scale, produce oxygen and extract the greenhouse gas CO2 from the environment. However, to do this they need add.....»»
Study shedding new light on Earth"s global carbon cycle could help assess liveability of other planets
Research has uncovered important new insights into the evolution of oxygen, carbon, and other vital elements over the entire history of Earth—and it could help assess which other planets can develop life, ranging from plants to animals and humans......»»
Measuring the atmospheres of other worlds to see if there are enough nutrients for life
Life on Earth depends on six critical elements: carbon, hydrogen, nitrogen, oxygen, phosphorous, and sulfur. These elements are referred to as CHNOPS, and along with several trace micronutrients and liquid water, they're what life needs......»»
Atom interferometer charters Navy"s inertial navigation path to reduce drift
U.S. Naval Research Laboratory (NRL) researchers have developed a patent-pending Continuous 3D-Cooled Atom Beam Interferometer derived from a patented cold and continuous beam of atoms to explore atom-interferometry-based inertial measurement systems.....»»
New method reveals hidden activity of life below ground
A team of scientists led by researchers at Bigelow Laboratory for Ocean Sciences have developed an innovative method to link the genetics and function of individual microbes living without oxygen deep below Earth's surface. Measuring both of these at.....»»
Research demonstrates anatase supported Ni single-atom catalysts for propane dehydrogenation
Propylene is one of the most important petrochemical raw materials, ranging second after ethylene. To meet the ever-increasing demand, alternative technologies for propylene production are in urgent need, among which the propane dehydrogenation (PDH).....»»
A chemically bonded photocatalyst with rich oxygen vacancies for improved photocatalytic decontamination
A challenge in promoting the industrial application of photocatalysis technology for environment remediation lies in the design of high-performance photocatalysts. These photocatalysts should be endowed with efficient photo-carrier separation and int.....»»
New satellite dataset sheds light on Earth"s plant growth
Gross Primary Production (GPP), the process through which plants convert carbon dioxide and sunlight into glucose and oxygen, is the Earth's largest carbon flux. Accurate quantification of GPP is crucial for understanding carbon budgets and their imp.....»»
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.....»»
Geometry-adaptive electrocatalysis: Proposed approach could double efficiency of energy conversion technologies
As the world seeks sustainable solutions to meet escalating energy demands, a collaborative team of researchers from the Universities of Tartu and Copenhagen has proposed an innovative approach to overcome long-standing limitations in oxygen electroc.....»»
Additional nutrients intensify dead zones in oceans, researchers find
As more and more nutrients from land and air enter the world's oceans, the dead zones without oxygen in the water will increase in size and intensity. That is the warning that Ph.D. student Zoë van Kemenade, an organic geochemist at NIOZ, draws from.....»»
Brazil"s Indigenous people turn to EU to save their savanna
An EU law banning deforestation-derived products comes into effect at the end of 2024, but for Brazilian Indigenous people it contains an unbearable loophole: the Cerrado, Brazil's vast wooded savanna, is excluded from its scope......»»
Hot post-asymptotic giant branch star discovered in globular cluster ESO 37-1
Astronomers have discovered a new post-asymptotic giant branch (PAGB) star in a Galactic globular cluster known as ESO 37-1 (or E3 for short) and derived its fundamental parameters. The finding is reported in a research paper published March 19 on th.....»»
Estimating coastal water depth from space via satellite-derived bathymetry
Since ancient times, knowing the depth of coastal waters has been key to safe and successful navigation and to exploit the sea's resources. Today, bathymetry—the measurement of sea depth—is even more important, playing essential roles in our unde.....»»
How do halibut migrate? Clues are in their ear bones
Rising temperatures, changes in major currents, oxygen depletion at great depths: the Gulf of St. Lawrence has undergone major changes in its environmental conditions in recent decades. That has put many species in danger and, as a consequence, made.....»»
Rose essential oil: A safe pesticide for organic agriculture
Plant-derived essential oils (EOs) find applications in various industries, such as detergents, cosmetics, pharmacology, and food additives. Moreover, EOs have an exceptional safety profile, and their numerous bioactivities greatly benefit human heal.....»»
Research reveals new starting points for the rapid and targeted development of future drugs
Many important medicines, such as antibiotics and anticancer drugs, are derived from natural products of bacteria. The enzyme complexes that produce these active ingredients have a modular design that makes them ideal tools for synthetic biology. By.....»»
Research suggests natural electrical grid deep inside Earth enables many types of microbes to survive
