New study finds the malaria parasite generates genetic diversity using an evolutionary "copy-paste" tactic
By dissecting the genetic diversity of the most deadly human malaria parasite—Plasmodium falciparum—researchers at EMBL's European Bioinformatics Institute (EMBL-EBI) have identified a mechanism of 'copy-paste' genetics that increases the genetic.....»»
Aroma compound found to reduce the effects of drought, improve productivity of tomato plants
Tomato plants emit a scent to resist bacterial attacks. This aroma—or volatile compound—is hexenyl butanoate (HB). A team from the Research Institute for Plant Molecular and Cellular Biology (IBMCP), a joint center of the Universitat Politècnica.....»»
Natural tech for "dimming" genes brings transformative potential to agriculture
Until the 1992 advent of a tomato that could delay softening, the fruit was picked green to withstand shipping. The delayed-softening trait was an example of the gene-silencing technique RNA interference, RNAi, before the underlying mechanism was und.....»»

Collaborative research that combined experiments at Yale University and molecular dynamics simulations at the Department of Energy's Oak Ridge National Laboratory provides new insights into solving a major technical obstacle to efficient and sustaina.....»»
Microalgae with unusual cell biology could lead to improved understanding of harmful algal blooms
What are the molecular processes in a unicellular marine algae species that can cause harmful algal blooms? A research team led by microbiologist Prof. Dr. Ralf Rabus from the University of Oldenburg (Germany) has conducted the first detailed analyse.....»»
The role of PbrChiA chitinase in ROS regulation and antifungal activity
Pear ring rot, a significant threat to pear production, is caused by Botryosphaeria dothidea, leveraging the complex dynamics of reactive oxygen species (ROS) during infection. Initially, plants employ their innate immune system, detecting pathogens.....»»
Communication between rotors in molecular motor observed for the first time
A pair of chemists at the University of Groningen in the Netherlands, has observed communication between rotors in a molecular motor. In their study, reported in the Journal of the American Chemical Society, Carlijn van Beek and Ben Feringa conducted.....»»
Ballistic transport in long molecular wires: Porphyrin nanoribbons
The conductance of classical electric components typically decays with increasing length. In general, this is also the same behavior found at the nanoscale with 1D molecular wires. Now, researchers have demonstrated that, once more, things are differ.....»»
A new type of metallacrown ether based on polyoxometalate opens research opportunities
Crown ethers were discovered in 1967. They were then modified by adding a metal-containing unit, creating metallacrown ethers. These metallacrown ethers have been the subject of intensive research. Depending on the molecular makeup of the metallacrow.....»»
Novel RNA- or DNA-based substances can protect plants from viruses, scientists show
Individually tailored RNA or DNA-based molecules are able to reliably fight off viral infections in plants, according to a new study by the Martin Luther University Halle-Wittenberg (MLU) published in the International Journal of Molecular Sciences......»»
Research team reveals cellular and molecular basis of spur development in Impatiens uliginosa
As an important reproductive organ of angiosperms, flowers have a clear purpose and adaptive significance in their various characteristics. As a typical floral evolutionary feature, the floral spur is a tubular structure extending from the petal, whi.....»»
Unlocking the mechanism of pineapple internal browning
Internal browning (IB) is a significant post-harvest issue in pineapples, impacting fruit quality and leading to substantial losses, yet its mechanism remains poorly understood. Studies have shown that the accumulation of phenolic compounds plays a k.....»»
Study elucidates regulation mechanism for electrocatalytic nitrate reduction
A research team led by Prof. Zhang Haimin from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has conducted a systematic study on the regulation mechanism of heterostructure bimetallic phosphide electrocatalysts to improv.....»»
Molecular mechanism of transmembrane bilirubin transport by human ABCC2 transporter revealed
The metabolic process of bilirubin has been a focus of medical research since the abnormal accumulation of bilirubin has been found to be associated with a variety of diseases. Bilirubin is a substance produced by the breakdown of aging or damaged re.....»»
Scientists discover why ripe fruit is more susceptible to necrotrophic pathogens than unripe fruit
In a recent study published in Molecular Plant, researchers have elucidated the mechanism underlying the increased susceptibility to necrotrophs during fruit ripening and have developed a rapid strategy to improve tomato fruit resistance to necrotrop.....»»
How molecular "handedness" emerged in early biology
Molecules often have a structural asymmetry called chirality, which means they can appear in alternative, mirror-image versions akin to the left and right versions of human hands. One of the great mysteries about the origins of life on Earth is that.....»»
Study reveals accelerated soil priming under climate warming
A first-of-its-kind study led by researchers at the University of Oklahoma highlights a crucial biosphere feedback mechanism and its effects on releasing soil carbon into the atmosphere......»»
Light stimulates a new twist for synthetic chemistry
Molecules that are induced by light to rotate bulky groups around central bonds could be developed into photo-activated bioactive systems, molecular switches, and more......»»
