Stem cell analyses could reveal how extra doses of some genes lead to the characteristics seen in males born with one or more surplus X chromosomes......»»
Study shows microbial diversity differences in volcanic cones and craters
Volcanic activity alters the Earth's surface and promotes the development of new ecosystems, providing valuable models for studying soil formation processes such as microbial composition and vegetation succession. Increasing evidence suggests that so.....»»
Organization of DNA in chromosomes can be explained by weak interactions between nucleosomes, research suggests
An article by UAB professor Joan-Ramon Daban analyzes in depth the physical problems associated with DNA packaging that have often been neglected in structural models of chromosomes......»»
Researchers aim to control gene expression by studying the memories of cells
Communication between cells is now believed to activate a memory mechanism that sustains gene expression, a finding based on the work of Dr. Gregory Reeves......»»
Century-old experiment secures beer and whiskey"s future
Thanks to an experiment started before the Great Depression, researchers have pinpointed the genes behind the remarkable adaptability of barley, a key ingredient in beer and whiskey. These insights could ensure the crop's continued survival amidst ra.....»»
Steve Biko"s murder exposed deep racism in how medicine was taught and practiced in South Africa
In 1966, Steve Biko began studying medicine at the University of Natal in South Africa, the same year that the general assembly of the United Nations declared apartheid a crime against humanity. As a young man, and a leading thinker, philosopher and.....»»
Studying fungi"s "weak link" to fight global rise in deadly fungal infections
A group of scientists at the Department of Energy's Oak Ridge National Laboratory have conducted neutron scattering research to reveal key information about fungus cell membranes that could aid in developing new antifungal treatments......»»
How context-specific factors control gene activity
Every cell in our body contains the same DNA, yet liver cells are different from brain cells, and skin cells differ from muscle cells. What determines these differences? It all comes down to gene regulation; essentially how and when genes are turned.....»»
Old satellite to burn up over Pacific in "targeted" re-entry first
After 24 years diligently studying Earth's magnetic field, a satellite will mostly burn up over the Pacific Ocean on Sunday during a "targeted" re-entry into the atmosphere, in a first for the European Space Agency as it seeks to reduce space debris......»»
Nature"s own chemistry could help reduce waste and improve health
Researchers are studying chemical processes in nature to develop new, cleaner means of chemical production and computers that can communicate with the human body......»»
Solving the side effect problem of siRNA drugs for genetic disease treatment
Small interfering RNA (siRNA) drugs are a class of therapeutic agents that silence specific genes associated with inherited diseases. However, siRNA drugs have challenges because siRNAs often silence genes other than the target ones, causing side eff.....»»
Angiosperms study provides insights into genome evolution after whole-genome duplications
Whole-genome duplication (WGD, or polyploidy) is a common and frequent occurrence in plants, providing raw genetic material for evolution. Homoeologs (duplicate genes from a WGD) often diverge in expression levels, while some still maintain similar (.....»»
Regulatory gene influences shape recognition in medaka fish, scientists discover
Medaka fish that lack functional Hmgn2 genes are unable to distinguish between simple shapes, revealing a new function for the regulatory gene......»»
New method captures the stochastic dynamics in coherent X-ray imaging at the nanoscale
Coherent X-ray imaging has emerged as a powerful tool for studying both nanoscale structures and dynamics in condensed matter and biological systems. The nanometric resolution together with chemical sensitivity and spectral information render X-ray i.....»»
Queer tabletop roleplaying games provide valuable lessons that even "Dungeons & Dragons" can learn from
By studying how some tabletop roleplaying games (TTRPGs) are putting queerness front and center, Northeastern researchers found ways even "D&D," the biggest TTRPG in the world, can be more welcoming and inclusive for players......»»
Cells use alternative splicing to regulate gene expression, research suggests
Alternative splicing is a genetic process where different segments of genes are removed, and the remaining pieces are joined together during transcription to messenger RNA (mRNA). This mechanism increases the diversity of proteins that can be generat.....»»
Data from space probes show that Alfvén waves drive the acceleration and heating of the solar wind
By studying data from NASA's Parker Solar Probe and the ESA Solar Orbiter, an international team of astrophysicists has found that Alfvén waves drive the acceleration and heating of the solar wind......»»
Researchers identify genes for low glycemic index and high protein in rice
A team of researchers at the International Rice Research Institute (IRRI) has identified genes and markers responsible for low glycemic index (GI) and high protein content in rice, using genetics and artificial intelligence classification methods......»»
Light microscopy study reveals molecular density changes during mitotic chromosome condensation
A team of scientists studying cell division developed a special light microscopy system and used it to analyze the molecular density of cellular environments. Their results provide a novel insight into mitotic chromosome condensation in living human.....»»
Sea anemone study identifies potentially regenerative stem cells linked to conserved genes
The sea anemone Nematostella vectensis is potentially immortal. Using molecular genetic methods, developmental biologists led by Ulrich Technau from the University of Vienna have now identified possible candidates for multipotent stem cells in the se.....»»
New tool simplifies cell tracking data analysis
Studying cell migration is vital because it plays a crucial role in many biological processes, including immune response, wound healing, and cancer metastasis. Understanding how cells move and behave can lead to breakthroughs in treating diseases, de.....»»
