A roadmap for gene regulation in plants
For the first time, researchers at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a genome-scale way to map the regulatory role of transcription factors, proteins that play a key role in gene expression.....»»
Ancient gene gives spiders their narrow waist, research reveals
An ancient gene is crucial for the development of the distinctive waist that divides the spider body plan in two, according to a study published August 29 in the open-access journal PLOS Biology by Emily Setton from the University of Wisconsin-Madiso.....»»
Scientists modify citrus pectin with induced electric field
Pectin, a natural and nontoxic acidic polysaccharide, is widely found in the primary cell wall and inner layer of terrestrial higher plants. The main domains of pectin are homogalacturonan and rhamnogalacturonan I, which contribute to the complexity.....»»
Study reveals distinct roles of H3K27me3 and H3K36me3 in winter wheat vernalization
Vernalization is the phenomenon whereby plants require prolonged exposure to low temperatures to flower. This ensures that overwintering plants undergo reproductive growth under suitable light and temperature conditions, thereby securing yield......»»
Drowning tomatoes for science
I can barely hear Esther Ngumbi over the roar of greenhouse fans as she shows me around her rooftop laboratory in Morrill Hall. The benches are full of tomato plants, and the tomatoes don't look good. Half of the plants are submerged in bins of water.....»»
Molecularly imprinted polymers help get the stink out of smoke-tainted wine
Wildfires can damage crops, even if flames come nowhere near the plants. One outcome can be an unpleasant flavor and smell of wine that is made from grapes exposed to smoke. But researchers report in the Journal of Agricultural and Food Chemistry tha.....»»
A chloroplast-mimicking nanoreactor for enhanced CO₂ electrocatalysis
Chloroplast, which is a double-membrane-bounded organelle, is the main site for CO2 fixation via photosynthesis in green plants. The double-membrane configuration can regulate the transport of substances into and out of the chloroplasts with the aid.....»»
New moves for self defense—how plants can inspire future soft robotic design
For plants, cleaning the air, providing food and medicines, and preserving our ecosystem is just another day's work. In the Department of Mechanical Engineering at Carnegie Mellon University, however, plants are being studied in new ways to inspire f.....»»
"Silent" mutations found to have repercussions beyond their own gene
Genetic disorders—like cystic fibrosis and Huntington's disease—are considered incurable, with gene mutations occurring in essentially every cell of the body. Gene mutations occur when one nucleotide in a codon is switched. In non-synonymous muta.....»»
Plant signaling pathways decoded using "optogenetic" tobacco plants
Using newly generated "optogenetic" tobacco plants, research teams from the University of Würzburg's Departments of Plant Physiology and Neurophysiology have investigated how plants process external signals......»»
Moths may use disco gene to regulate day/night cycles
How does one species become two? If you're a biologist, that's a loaded question. The consensus is that, in most cases, the process of speciation occurs when individuals from a single population become geographically isolated. If they remain separate.....»»
Wood charcoal reveals the existence of a variety of woody plants around early millet sites
A study led by Hui Shen, Keliang Zhao, Xinying Zhou, Xiaoqiang Li from the Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences, and Zhenwei Qiu from the National Museum of China has reconstructed how early millet f.....»»
OpenAI gets called out for opposing a proposed AI safety bill
"When actual regulation is on the table, he opposes it," the researchers wrote of OpenAI CEO Sam Altman......»»
Elon Musk foreclosing on former home of actor Gene Wilder
Tesla's CEO sold the home, which is down the street from where Lee Iacocca used to live, in 2020 when he was getting rid of some possessions......»»
Darwin"s fear was unjustified: Study suggests fossil record gaps not a major issue
Fossils are used to reconstruct evolutionary history, but not all animals and plants become fossils and many fossils are destroyed before we can find them (e.g., the rocks that contain the fossils are destroyed by erosion). As a result, the fossil re.....»»
Research sheds light on low crop yields and their impact on small farms
Northeastern University professor Gabriela Garcia studies the relationship between people and plants......»»
From leaf to cup: The essential role of magnesium in tea plant metabolism
Magnesium plays a vital role in the growth and quality of tea plants, influencing key processes such as photosynthesis and the synthesis of important metabolites. However, tea plants often suffer from magnesium deficiency due to factors like poor soi.....»»
New genetic sensor for DNA methylation discovered
DNA methylation is a process in which a methyl group is attached to the cytosine base of the DNA molecule, and is a major way that DNA is epigenetically marked. Epigenetic modifications can act as on–off switches to regulate gene expression and hel.....»»
Manganese nanoparticles can more than double availability of world"s potable water, say scientists
Manganese ferrite nanoparticles could lead to a substantial surge in the availability of drinking water globally when used to modify the filtering sheets currently used in water treatment plants, according to scientists......»»
Scientists call for an update in environmental decision making that takes human rights into account
Human well-being is connected to nature for food, climate regulation and culture, making the protection of nature a human rights matter......»»
VW scales back plans for battery cell plants in Europe, North America
VW expects to start production next year at a new gigafactory in Germany, but said it may take longer to scale up battery cell capacity at plants in Spain and Canada......»»
