Mechanism of cobalt–manganese catalysts deciphered
Conventional catalysts for hydrogen production via water electrolysis usually contain precious metals and are expensive. However, cheaper alternatives have been developed, for example cobalt–manganese catalysts. They have a high activity and are st.....»»
Phenomenal phytoplankton: Scientists uncover cellular process behind oxygen production
Take a deep breath. Now take nine more. According to new research, the amount of oxygen in one of those 10 breaths was made possible thanks to a newly identified cellular mechanism that promotes photosynthesis in marine phytoplankton......»»
Examining the developmental regulatory mechanism of limb loss in squamates
The development of limbs is significant for the origin and evolution of tetrapods, providing multiple functions and capabilities. Although limb loss has occurred in many clades to adapt to new environments, it is particularly common in Squamata, whic.....»»
Researchers shed further light onto zinc homeostasis in cells
A research group has unearthed how zinc transporter complexes regulate zinc ion (Zn2+) concentrations in different areas of the Golgi apparatus and revealed that this mechanism finely tunes the chaperone protein ERp44......»»
Theoretical biologists uncover novel mechanism for flight control in fruit flies
Researchers at the Institute for Theoretical Biology at Humboldt Universität have solved a long-standing mathematical puzzle about the emergence of electrical activity patterns during insect flight. Together with colleagues at the Johannes Gutenberg.....»»
Astronomers discover a key planetary system for understanding formation mechanism of mysterious "super-Earths"
A study led by researchers of the University of Liège and the CSIC—using observations from NASA's TESS telescope—presents the detection of a system of two planets slightly larger than Earth orbiting a cold star in a synchronized dance. Named TOI.....»»
Switzerland is turning the gap between train tracks into a ‘solar carpet’
A startup called Sun-Ways developed a mechanism that can turn unused space between train tracks into a long and narrow solar farm. Solar power is key to a clean energy future, but many people don’t want large-scale solar farms in their backya.....»»
How plants use sugar to produce roots
Along with sugar reallocation, a basic molecular mechanism within plants controls the formation of new lateral roots. An international team of plant biologists has demonstrated that it is based on the activity of a certain factor, the target of rapam.....»»
Study reveals generation mechanism of radiative effects on novel active optical hyperspectral LiDAR system
Both the geometric and spectral information of the target are available with the hyperspectral light detection and ranging (LiDAR) in a single measurement. This advanced technique extends the scope of imaging spectroscopy to spectral three-dimensiona.....»»
Zerto Cyber Resilience Vault allows users to monitor for encryption-based anomalies
Zerto launched a new real-time encryption detection mechanism and air-gapped recovery vault for enhanced hybrid cloud protection and security against cyber threats. These new features are part of Zerto 10, which includes advanced detection mechanisms.....»»
Uncovering the mechanism of photoexcited nucleobases: Is decay fast or suppressed?
The nucleobase molecules carrying the genetic codes are the most important ingredients for life, but they are also very vulnerable. When the ultraviolet component in the sunlight irradiates these molecules, the electrons in the molecules will be exci.....»»
Understanding how the "heart" of the plant works may lead to protection from pathogens
Plants, like humans, need to move sugar and other nutrients around their bodies to power their growth. But unlike humans, they do not have a heart to pump these vital nutrients. Instead, they use an amazing molecular pump mechanism that scientists ha.....»»
Researchers demonstrate high natural radioactivity of manganese nodules
Manganese nodules at the bottom of the deep sea contain a wealth of valuable metals that are vital to the electronics and steelmaking industries. Accordingly, these sectors and many countries have pinned their hopes on deep-sea mining to meet the gro.....»»
Chemists unravel reaction mechanism for clean energy catalyst
Hydrogen, the simplest element on Earth, is a clean fuel that could revolutionize the energy industry. Accessing hydrogen, however, is not a simple or clean process at all. Pure hydrogen is extremely rare in nature, and practical methods to produce i.....»»
Researchers discover that various species share a similar mechanism of molecular response to nanoparticles
Researchers at FHAIVE (Finnish Hub for Development and Validation of Integrated Approaches), Tampere University, have discovered a new response mechanism specific to exposure to nanoparticles that is common to multiple species......»»
Mechanisms for removal of strong, replication-blocking lesions generated by the human HMCES protein
Researchers at Nagoya University and Osaka University in Japan have found novel repair pathways of apurinic/apyrimidinic (AP) sites of DNA. Repair of the base excision, which repairs AP sites, is an essential mechanism for cell survival. Its dysfunct.....»»
Research team explores the mechanism of tropical expansion under changing climate
Scientific evidence shows that the tropical belt around the middle of the globe is expanding. For years scientists have proposed different mechanisms that might explain this expansion. A team of researchers has now determined that the poleward advanc.....»»
