When plants flower: Scientists ID genes, mechanism in sorghum
Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and Oklahoma State University have identified key genes and the mechanism by which they control flowering in sorghum, an important bioenergy crop. The findings, just p.....»»
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.....»»
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.....»»

Researchers identify materials capable of catalyzing the conversion of ortho-hydrogen to para-hydrogen
A research team consisting of NIMS and the Tokyo Institute of Technology has identified materials capable of catalyzing the conversion of ortho-hydrogen to para-hydrogen. These catalysts should be essential to the spread of mass-transportation/storag.....»»
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.....»»
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......»»
New aging mechanism discovered in nematodes
Even the genes and proteins that have been most closely studied are still far from having given up all their secrets. Like a Swiss Army knife, they have many different, often unknown functions......»»
Cracking the code to a healthier potato chip
In a breakthrough for the snack food industry, a team of scientists led by Michigan State University professors Jiming Jiang and David Douches has discovered a key mechanism behind the darkening and potential health concerns associated with cold-stor.....»»
After EV price cuts, cheaper batteries could be just what automakers need
Sharp price declines for lithium, cobalt, nickel and other materials are lowering battery costs, allowing automakers who are slashing EV prices to maintain their margins......»»
Newly discovered bacterial defense system functions as self-destruct button
Wageningen researchers have discovered a molecular self-destruct mechanism in a bacterium living on seaweed. With this mechanism the bacteria sacrifice themselves when they are infected, thus protecting their brothers and sisters from infections. By.....»»
