Lost in space? Just use relativity
One of the hardest things for many people to conceptualize when talking about how fast something is going is that they must ask, "Compared to what?" All motion only makes sense from a frame of reference, and many spacecraft traveling in the depths of.....»»
Polyploidy and long-distance dispersal jointly shape global species diversification in yellowcress, finds study
Long-distance dispersal (LDD) is one of the most important biogeographical processes. Polyploidy, or whole-genome duplication, has long been proposed as an intrinsic feature of LDD. However, it is still unclear how and to what extent polyploidy inter.....»»
Researchers fill the final gaps in the Arabidopsis genome sequence
Arabidopsis thaliana is a species grown worldwide for genetic research and was the first plant to have its complete set of chromosomes (its genome) sequenced......»»
Sex chromosomes responsible for much more than determining sex, study shows
Human sex chromosomes originated from a pair of autosomes, the ordinary or non-sex chromosomes that contain the majority of our genome and come in identical pairs. That ancestral pair of autosomes diverged to become two different chromosomes, X and Y.....»»
Scientists sequence genome for threatened whitebark pine
Researchers have sequenced the whitebark pine genome, presenting new opportunities to help the threatened, high-altitude tree endure environmental challenges......»»
New understanding of ancient genetic parasite may spur medical breakthroughs
A multidisciplinary study published in Nature has elucidated the structure of the machinery responsible for writing much of our "dark genome"—the 98% of our DNA that has largely unknown biological function. These results may spur entirely novel tre.....»»
New study eyes nutrition-rich chia seed for potential to improve human health
Oregon State University scientists have sequenced the chia genome and in doing so provided a blueprint for future research that capitalizes on the nutritional and human health benefits of the plant......»»
New comprehensive genome data on soil invertebrates provide insights into their biodiversity
With the "MetaInvert" project, scientists are providing extensive genomic data on 232 species of previously little-studied organisms. They are tiny, enormously diverse, and widespread in the soil: soil invertebrates such as springtails, horn mites, m.....»»
Toxic comments associated with reduced activity of volunteer editors on Wikipedia
A study links hostility on Wikipedia to lost productivity on the site. Wikipedia, the largest reference work ever created, is written and edited by tens of thousands of volunteers, known as Wikipedians. Despite the fact that anyone can edit any page,.....»»
New enzyme allows CRISPR technologies to accurately target almost all human genes
A team of engineers at Duke University have developed a method to broaden the reach of CRISPR technologies. While the original CRISPR system could only target 12.5% of the human genome, the new method expands access to nearly every gene to potentiall.....»»

Clonal fish: Same genes, same environment, different fitness levels
According to current knowledge, individuality is determined by either differences in genome or in the apparent environmental conditions. However, studies show, the paradigm of twin research is currently crumbling......»»
Team discovers protein crucial for B cell differentiation and antibodies
A cell nucleus is a busy place. Cellular proteins twist and pull DNA, folding the genome into intricate 3D structures that support functioning of its coding parts......»»
Comprehensive analysis of the telomere-to-telomere genome of soybean cultivar ZH13
Soybean (Glycine max) is one of the most crucial oil and protein crops, and contributes to more than a quarter of the protein utilized in both human food and animal feed. It is widely acknowledged that the cultivated soybean emerged through the domes.....»»
Physicists model chromosome folding, reveal how loops affect spatial organization of the genome
Human chromosomes are long polymer chains that store genetic information. The nucleus of each cell contains the entire human genome (DNA) encoded on 46 chromosomes with a total length of about 2 meters. To fit into the microscopic cell nucleus and at.....»»
Unlocking citrus tolerance secrets: The Valencia sweet orange genome and the fight against HLB disease
Sweet orange (Citrus sinensis L.), a hybrid fruit crop originating from mandarins (Citrus reticulata Blanco) and pummelos [Citrus maxima (Burm.) Merr.], exhibits complex genomic diversity due to ancient interspecific hybridization. At present, the be.....»»

3D folding of the genome: Theoretical model helps explain how cell identity is preserved when cells divide
Every cell in the human body contains the same genetic instructions, encoded in its DNA. However, out of about 30,000 genes, each cell expresses only those genes that it needs to become a nerve cell, immune cell, or any of the other hundreds of cell.....»»
