Using an egg "soup" to understand how DNA is packed in the nucleus
If you stretched the DNA found in one of your cells from end to end, it would extend approximately 2 meters or 6.5 feet. Every single cell in your body can pack away this much DNA by winding it around proteins called histones. The DNA is opened and c.....»»
Scientists discover "selfish DNA" crucial for early human development
A critical transition in early human development is regulated not by our own genes, but by DNA elements called transposons that can move around the genome, Sinai Health researchers have found......»»
First coherent picture of an atomic nucleus made of quarks and gluons
The atomic nucleus is made up of protons and neutrons, particles that exist through the interaction of quarks bonded by gluons. It would seem, therefore, that it should not be difficult to reproduce all the properties of atomic nuclei hitherto observ.....»»
Invisible text that AI chatbots understand and humans can’t? Yep, it’s a thing.
A quirk in the Unicode standard harbors an ideal steganographic code channel. What if there was a way to sneak malicious instructions into Claude, Copilot, or other top-name AI ch.....»»
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.....»»
Compound drought–heat wave events under-recognized in global soils, finds study
Soil is essential for life and plays a crucial role in the Earth's ecosystem, providing support for plant roots and hosting countless microorganisms. In a warming world, it is important to understand how soil hydrothermal conditions, particularly the.....»»
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".....»»
Study: Disappointment, not hatred is driving polarization in the states
A new study is redefining how we understand affective polarization. The study proposes that disappointment, rather than hatred, may be the dominant emotion driving the growing divide between ideological groups......»»
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.....»»
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.....»»
Google identifies low noise “phase transition” in its quantum processor
Benchmark may help us understand how quantum computers can operate with low error. Back in 2019, Google made waves by claiming it had achieved what has been called "quantum suprem.....»»
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—.....»»
Experimental archaeology sheds light on skill and technique in Bronze Age spear combat
How can we tell whether and how a prehistoric weapon was used? How can we better understand the dexterity and combat skills involved in Bronze Age spear fighting?.....»»
Male locusts serve as parasols for females during egg laying in the hot sun
A team of entomologists at Center National de Lutte Antiacridienne's Mauritanian National Desert Locust Center has found that male locusts will mount a female when she is laying eggs during the heat of day......»»
Goodnotes adds an AI that can read and explain even the worst handwriting
Goodnotes releases AI tools to read and understand handwritten notes......»»
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.....»»
iPhone 16 vs. iPhone 15: How are they different?
Apple’s iPhone 16 arrives with a few familiar updates over the iPhone 15, but the biggest changes are looking to come with Apple Intelligence This iPhone 16 vs. iPhone 15 comparative analysis will help you understand the differences between t.....»»
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.....»»
