Exploring the role of hydrogen sulfide in the expression of iron uptake genes in E. coli
Antibiotic resistance and oxidative stress response are important biological mechanisms that help bacteria thrive, especially pathogenic bacteria like Escherichia coli. Hydrogen sulfide (H2S), a chemical messenger molecule, regulates several intracel.....»»
Advancements in genomic research reveal alternative transcription initiation sites in thousands of soybean genes
Rosalind Franklin, James Watson and Francis Crick discovered the structure of DNA—that molecular blueprint for life—over 70 years ago. Today, scientists are still uncovering new ways to read it......»»
Report: DOJ wants to force Google Chrome sale, Android de-bundling
Cutting off Google's control of the world's most popular browser may be necessary. Preferred by 61 percent of Internet users, Google's Chrome browser plays too big a role in maint.....»»
Seemingly "broken" genes in coronaviruses may be essential for viral survival
Viruses are lean, mean, infection machines. Their genomes are tiny, limited to a handful of absolutely essential genes, and they shed extra genomic deadweight extremely fast... usually......»»
By exerting "crowd control" over mouse cells, scientists make progress towards engineering tissues
Genes aren't the sole driver instructing cells to build multicellular structures, tissues, and organs. In a paper published in Nature Communications, USC Stem Cell scientist Leonardo Morsut and Caltech computational biologist Matt Thomson characteriz.....»»
AI-generated shows could replace lost DVD revenue, Ben Affleck says
AI won't replace human artistry, says actor, but it will wildly drive down costs. Last week, actor and director Ben Affleck shared his views on AI's role in filmmaking during the.....»»
Electron imaging reveals the vibrant colors of the outermost electron layer
Surfaces play a key role in numerous chemical reactions, including catalysis and corrosion. Understanding the atomic structure of the surface of a functional material is essential for both engineers and chemists. Researchers at Nagoya University in J.....»»
Extreme heat weakens land"s power to absorb carbon, analysis finds
A new European Space Agency-backed study shows that the extreme heat waves of 2023, which fueled huge wildfires and severe droughts, also undermined the land's capacity to soak up atmospheric carbon. This diminished carbon uptake drove atmospheric ca.....»»
Genes of ancient animal relatives used to grow a mouse: Study reveals hidden history of stem cells
An international team of researchers has achieved an unprecedented milestone: the creation of mouse stem cells capable of generating a fully developed mouse using genetic tools from a unicellular organism, with which we share a common ancestor that p.....»»

The role of interculturalism in higher music education
By reimagining educational practices to include diverse cultural perspectives and community engagement, institutions can cultivate a new generation of artists who are not only skilled musicians but also empathetic and socially responsible global citi.....»»
Study uncovers role of tissue viscoelasticity in cell response
To the casual eye, a memory foam mattress would appear to have no relationship to the behavior of cells and tissues. But an innovative study carried out at the Centro de Investigaciones Cardiovasculares (CNIC) in Madrid shows that viscoelasticity—t.....»»
One or many? Exploring the population groups of the Antarctic blue whale using historical mark-recovery data
Hunted nearly to extinction during 20th century whaling, the Antarctic blue whale, the world's largest animal, went from a population size of roughly 200,000 to little more than 300. The most recent estimate in 2004 put Antarctic blue whales at less.....»»
AI’s impact on the future of web application security

Decline in West African coastal fish stocks threatens food security and livelihoods
Small-scale fisheries play a vital role in providing food and livelihoods for millions of people around the world, particularly in low-income countries in Africa. However, there is limited statistical data on the composition, abundance, and distribut.....»»
Climate change: Women"s role in the economy is key to a just transition
The realities of climate change are hitting home for many people living in the Global South. Food security, water access and health have been jeopardized by increased temperatures, extreme weather events and sea level rise......»»
Discovery of 2,586 orphan genes in Rosa chinensis reveals stress adaptation and flower development
Orphan genes, found only in specific lineages, are key drivers of new functions and phenotypic traits. This discovery lays a foundation for understanding how roses thrive under environmental challenges......»»
A strategy of ligand-protected direct hydrogen reduction to prepare bimetallic cluster catalysts
Researchers have developed a ligand-protected direct hydrogen reduction strategy to prepare zeolite-confined Pt-Pd bimetallic cluster catalysts. These catalysts efficiently facilitate hydrogen production from ammonia borane (AB) solvolysis and the ta.....»»
