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......»»
Glowing proteins enable real-time, 3-D study of essential enzymes
Working in organoid models, researchers at University of California San Diego School of Medicine have developed a new tool to study protein-kinase C (PKC) enzymes, which play a critical role in cell growth, differentiation and survival. Malfunction o.....»»
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.....»»
Analysis of approximately 75 million publications finds those employing AI are more likely to be a "hit paper"
From designing new drug candidates in medicine to drafting new taxation policies in social sciences, the benefits of artificial intelligence (AI) in scientific research are all around......»»
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".....»»
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.....»»
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.....»»
Hubble and New Horizons offer dual perspectives on Uranus to inform exoplanet research
NASA's Hubble Space Telescope and New Horizons spacecraft simultaneously set their sights on Uranus recently, allowing scientists to make a direct comparison of the planet from two very different viewpoints. The results inform future plans to study l.....»»
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—.....»»
The Nobel Prize in physics is being awarded, a day after 2 Americans won the medicine prize
The Nobel Prize in physics is being awarded Tuesday, a day after two American scientists won the medicine prize for their discovery of microRNA......»»
Singapore families show high resilience during pandemic
A recent study by the National University of Singapore Yong Loo Lin School of Medicine (NUS Medicine) analyzing the resilience of Singaporean families during the COVID-19 pandemic has uncovered significant findings that highlight how most families wi.....»»
Nobel Prize in medicine awarded for discovery of microRNAs, the molecules that control our genes
Two scientists, Victor Ambros (UMASS Chan Medical School in the US) and Gary Ruvkun (Harvard Medical School in the US), have won the 2024 Nobel prize in medicine or physiology......»»
Medicine Nobel goes to previously unknown way of controlling genes
MicroRNAs control the activity of many key genes but were unknown before 1993. On Monday, the Nobel Committee announced that two US researchers, Victor Ambros and Gary Ruvkun, wil.....»»
Winning the Nobel "an earthquake", says Ruvkun
US scientist Gary Ruvkun, who on Monday won the Nobel Prize in Medicine with fellow American Victor Ambros for their discovery of microRNA, said winning the honor was like "an earthquake"......»»
New polymer design breaks the tradeoff between toughness and recyclability
Plastics underpin much of modern life—areas like medicine, technology, and food safety would be unrecognizable without plastics and their useful properties. However, the toughness of plastics, which is often desirable, also makes them a dangerous p.....»»
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.....»»
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.....»»
