Beyond changing DNA itself, mutagens also cause errors in gene transcription
Exposure to mutagens, or mutation-causing agents, can not only bring about changes in DNA but also appear to induce errors when genes are transcribed to make proteins, which may be an important factor in age-related diseases......»»
How "vaccinating" plants could reduce pesticide use and secure global food supplies
In a growing and changing world, we need to find ways of putting food on everyone's table. Pesticides have enabled mass cultivation on an incredible scale, but they can have harmful secondary effects on humans and wildlife, and pests are rapidly evol.....»»
Changing watering practices to improve tomato plant health
Some people believe that talking to your plants makes them thrive. While there's limited scientific support for sound improving plant health, there's a growing amount of evidence about the benefits of mechanical stimulation, like touch, wind or rain......»»
Protein USP50 identified as key in DNA replication balance
A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified in a new study......»»
Expansion in situ genome sequencing innovation makes hidden DNA-protein interactions visible
Harvard scientists have unveiled a new technique called expansion in situ genome sequencing (ExIGS) that combines existing in situ genome sequencing (IGS) with expansion microscopy (ExM). The innovation allowed researchers to link nucleus abnormaliti.....»»
Atmospheric rivers are shifting poleward, reshaping global weather patterns
Atmospheric rivers—those long, narrow bands of water vapor in the sky that bring heavy rain and storms to the U.S. West Coast and many other regions—are shifting toward higher latitudes, and that's changing weather patterns around the world......»»
Scientists develop a new method to study gene function in cells and tissue
The Gaublomme lab has developed a new optical pooled screening approach called CRISPRmap, which enables the coupling of optical properties of single cells to targeted genetic perturbations. Optical phenotypes are typically inaccessible for sequencing.....»»
Research vessel provides comprehensive assessment of the changing Central Arctic Ocean
Sparse sea ice, thousands of data points and samples, a surprising number of animals and hydrothermal vents—those are the impressions and outcomes that an international research team is now bringing back from a Polarstern expedition to the Central.....»»
iOS 18 fixed my motion sickness problem with one new feature
Apple can sometimes dip into hyperbole with its marketing. But every now and then, a new iPhone or software feature truly is “life changing.” For me this year, that feature has been Vehicle Motion Cues in iOS 18, which fixed my motion sickness......»»
Chemists develop chiral DNA catalysts for asymmetric catalysis
Chemists from the National University of Singapore (NUS) have developed a way to make diverse chiral deoxyribonucleic acid (DNA) catalysts by merging DNA repair with biorthogonal chemistry, paving the way for more efficient and versatile approaches t.....»»
Hidden in the teeth: DNA study finds these 19th century lions preyed on humans and giraffes
In 1898, two male lions terrorized an encampment of bridge builders on the Tsavo River in Kenya. The lions, which were massive and maneless, crept into the camp at night, raided the tents and dragged off their victims. The infamous Tsavo "man-eaters".....»»
Committed a workplace gaffe? You will survive it (and you may even get promoted)
Nearly everybody has emailed the wrong thing to the wrong person at the wrong time. It's a leveler in modern workplaces. The consequences of errors may be immense or trivial, but not much can change that now. The error was your doing: you underperfor.....»»
Key gene discovered for regulating rice grain length
Recently, a research team led by Professor Wu Yuejin from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, discovered a key gene that can influence rice grain length by regulating cell proliferation, the RGL2 gene. This pr.....»»
Advanced model predicts gene architecture via nucleosome position
DNA—the molecule that carries the genetic information of all living organisms—is packaged within cells in a complex manner that allows it to function efficiently. Nucleosomes facilitate DNA compaction and also play a crucial role in regulating ge.....»»
Apple hosted ‘Global Police Summit’ to help law enforcement use its products better, per report
Typically when Apple and law enforcement are in the news together, it’s because of a standoff over user privacy. But today, a new report outlines the company’s efforts to build bridges with law enforcement—efforts that may be changing. more.....»»
Scientists explore whether smaller chromosomes lead to more segregation errors during egg cell division
Three RIKEN researchers have shed light on the cellular mechanisms underlying chromosomal abnormalities that can cause miscarriages and congenital disorders such as Down syndrome......»»
Using a unique combination of DNA techniques to authenticate ginseng supplements and combat adulteration
Rosalee Hellberg, an associate professor in Chapman University's Food Science Program, and her research team have made a significant breakthrough in the fight against adulteration in dietary supplements. Effective methods for identifying adulteration.....»»
You get your energy from your mom. A new study explains why
It's one of the basic tenets of biology: We get our DNA from our mom and our dad. But one notable exception has perplexed scientists for decades: Most animals, including humans, inherit the DNA inside their mitochondria—the cell's energy centers—.....»»
Researchers reveal key mechanism in regulating DNA recombination
Meiotic recombination generates genetic diversity and promotes proper chromosomal segregation of parental chromosomes. This process requires a set of recombinases polymerized on single-stranded (ss) DNAs called the nucleoprotein filament to undergo h.....»»
OpenAI unveils major ChatGPT redesign with new ‘Canvas’ interface for writers and coders
OpenAI announced a new design interface called 'canvas,' which makes it easier for users to revise writing and coding projects. Here's what it looks like. OpenAI is changing up ChatGPT's interface to look more like a digital notepad for project.....»»
Engineers create a chip-based tractor beam for biological particles
MIT researchers have developed a miniature, chip-based "tractor beam," like the one that captures the Millennium Falcon in the film "Star Wars," that could someday help biologists and clinicians study DNA, classify cells, and investigate the mechanis.....»»
