Unraveling the DNA mystique of Saposhnikovia divaricata: New horizons in herbal medicine
Scientists have decoded the genetic blueprint of Saposhnikovia divaricata, a traditional medicinal herb. Their research provides a detailed genome sequence, shedding light on the plant's evolutionary adaptations and the genetic foundations of its the.....»»
Study reveals how transcription factors navigate DNA architecture to shape cellular identity
A new study led by Prof. Yosef Buganim from the Hebrew University of Jerusalem and Dr. Abdenour Soufi from the University of Edinburgh reveals how transcription factors (TFs)—key proteins that regulate gene activity—navigate DNA and chromatin str.....»»
New method maps hundreds of proteins in cell nuclei simultaneously
Caltech researchers have developed a new method to map the positions of hundreds of DNA-associated proteins within cell nuclei all at the same time. The method, called ChIP–DIP (Chromatin ImmunoPrecipitation Done In Parallel), is a versatile tool f.....»»
A biochip for fish detection using eDNA
Dolly Varden is a rare species of fish found in the Nooksack River basin of northwestern Washington state. Although they have flyrods in tow, Trout Unlimited volunteers' primary tool of choice is an environmental DNA (eDNA) sampling kit. This tool en.....»»
New method speeds up protein study, aiding disease treatment research
Protein complexes are important for the majority of vital processes in the cell and human body, such as producing energy, copying DNA and regulating the immune system......»»
Saturday Citations: M87* lashes out; a deep sleep discovery; proposal to build a digital cell
I love it when researchers observe an extra-weird particle, and this week, scientists reported the observation of a particle that only has mass when it's moving in a single direction. Good enough! An ancient DNA analysis suggests that Neanderthals an.....»»
A new twist: The molecular machines that loop chromosomes also twist DNA
Scientists from the Kavli Institute of Delft University of Technology and the IMP Vienna Biocenter have discovered a new property of the molecular motors that shape our chromosomes. While six years ago they found that these so-called SMC motor protei.....»»
Neanderthal-human interbreeding lasted 7,000 years, new study reveals
A new analysis of DNA from ancient modern humans (Homo sapiens) in Europe and Asia has determined, more precisely than ever, the time period during which Neanderthals interbred with modern humans, starting about 50,500 years ago and lasting about 7,0.....»»
Ancient genomes link early Europeans to Neanderthal ancestry
After modern humans left Africa, they met and interbred with Neanderthals, resulting in around 2–3% Neanderthal DNA that can be found in the genomes of all people outside Africa today. However, little is known about the genetics of these first pion.....»»
Studies pin down exactly when humans and Neanderthals swapped DNA
We may owe our tiny sliver of Neanderthal DNA to just a couple of hundred Neanderthals. Two recent studies suggest that the gene flow (as the young people call it these days) betw.....»»
How a piece of plastic shut down DNA testing at crime lab
It was technically a successful scientific discovery when analysts at the Hennepin County, Minnesota, forensic science lab recognized there was a contaminant somewhere in its DNA process. That did not lessen the sense of dread......»»
Fast, rewritable computing with DNA origami registers
DNA stores the instructions for life and, along with enzymes and other molecules, computes everything from hair color to risk of developing diseases. Harnessing that prowess and immense storage capacity could lead to DNA-based computers that are fast.....»»
Indiana Jones and the Great Circle: all Vatican Medicine Bottle locations
Most collectibles in Indiana Jones and the Great Circle are not immediately useful, but Medicine Bottles can give you a massive edge if you can find them all......»»
Computer modeling shows close encounters between distant DNA regions cause bursts of gene activity
Researchers at Kyushu University have revealed how spatial distance between specific regions of DNA is linked to bursts of gene activity. Using advanced cell imaging techniques and computer modeling, the researchers showed that the folding and moveme.....»»
Finding traces of fish with DNA from water samples
Silje Halvorsen bends down and fills a plastic bottle with water from Gillsvannet lake, a sheltered bathing spot just outside the center of Kristiansand......»»
Historical outbreaks of coffee wilt disease linked to gene transfer from another fungus
The fungus that causes coffee wilt disease repeatedly took up segments of DNA from a related fungal pathogen, which contributed to successive outbreaks of the disease. Lily Peck of Imperial College London, U.K., reports these new findings in a study.....»»
Polarization photodetector that mimics desert ant offers pathway for more sensitive, miniaturized imaging systems
Polarization photodetectors (pol-PDs) have widespread applications in geological remote sensing, machine vision, and biological medicine. However, commercial pol-PDs usually require bulky and complicated optical components and are difficult to miniat.....»»
Scientists develop ultrasound-based technique as a tool for directing cell growth and orientation
Developing reliable methods to replace dead or damaged tissue is one of the primary goals of regenerative medicine. With steady advances in tissue engineering and biomedicine, scientists are almost at a point where growing cell sheets in the lab and.....»»
Hidden DNA in plants reveals secrets of photosynthesis
Scientists have uncovered genetic variation in the unexplored DNA of the photosynthetic and energy factories of Arabidopsis plants, which plays a crucial role in the efficiency of photosynthesis in plants. These insights—published Nov. 27 in the Pr.....»»
