AMD starts bringing its own tiny CPU cores to new Ryzen 7040 laptop chips
AMD has already announced some of these chips without mentioning Zen 4c cores. Enlarge / Unlike Intel's E-cores, AMD's Zen 4c supports all the same capabilities as Zen 4, just in a smaller package with lower clock speeds. (credit.....»»
Okinawa"s ants show reduced seasonal behavior in areas with more human development
Insects have an important role in maintaining the health of ecosystems, but our understanding of how human activities affect their populations is limited. This gap in knowledge is worrying because of the decline of insect populations and the severe c.....»»
Gene discovery may help growers battle grape downy mildew
Researchers at Cornell have discovered a new grape downy mildew resistance gene—giving the wine and grape industry a powerful new tool to combat this devastating disease......»»
Scientists identify gene that triggers dramatically increased root growth
Oak Ridge National Laboratory scientists identified a gene "hotspot" in the poplar tree that triggers dramatically increased root growth. The discovery supports the development of better bioenergy crops and other plants that can thrive in difficult c.....»»
The intricate mechanisms of epigenetic silencing
Epigenetic silencing, which involves the suppression of gene activity, is a fascinating and increasingly influential branch of biological sciences. It allows cells to remember and maintain specific gene expression patterns throughout development and.....»»
Why Antidepressants Take So Long to Work
A clinical trial reveals the first evidence of how the brain restructures physically in the first month on SSRIs—and the link between neuroplasticity and depression......»»
The sun"s activity cycle is reaching its peak early—knowing why could help us unlock the secrets of our star
Our sun is a steady and everlasting companion. Reliable like a clock, its apparent passage across the sky allows us to measure time. The sun and its path is also the source of Earth's seasons. But in many respects, our sun is far from calm and unchan.....»»
Bizarre new fossils shed light on ancient plankton
A scientist from the University of Leicester has discovered a new type of fossil that reveals life in the oceans half a billion years ago. The tiny organisms, detailed in a new study in the journal Proceedings of the Royal Society B: Biological Scien.....»»
Gene integral to initiating, sustaining sperm cell development identified
With male infertility a mounting global concern impacting approximately 12% of men, according to the National Institutes of Health, a Penn State research team has discovered a gene that plays a key role in initiating and sustaining spermatogenesis. T.....»»
Study reveals transition from Pangea megamonsoon to modern global monsoon
The seasonal reversal of land-sea thermal contrast drives the monsoon system—the dominant seasonal mode of the global hydrological cycle that influences the livelihood of billions of people. But how did the modern global monsoon develop?.....»»
Biological fingerprints in soil show where diamond-containing ore is buried
Researchers have identified buried kimberlite, the rocky home of diamonds, by testing the DNA of microbes in the surface soil......»»
How do kingfishers avoid concussions when diving? It might be in their genes
Mutations in the MAPT gene associated with tau proteins seem to play a significant role. Enlarge / Fish-eating kingfishers execute plunging dives into the water to capture prey, yet never seem to get concussed. (credit: Richard T.....»»
How mosquito-controlling bacteria might also enhance insect fertility
A new study reveals biological mechanisms by which a specific strain of bacteria in the Wolbachia genus might enhance the fertility of the insects it infects—with potentially important implications for mosquito-control strategies. Shelbi Russell of.....»»
New methods for effective transport of large genes in gene therapy
One problem in gene therapy is that not all genes transfer equally well into the target cells. UZH researchers have now developed a flexible method to transfer large genes efficiently and without significant side effects. The approach has strong pote.....»»
JcSEUSS1 shown to play negative role in regulating reproductive growth of Jatropha curcas
In Arabidopsis, rice and tomato, the SEUSS gene encodes a transcriptional adaptor as well as a nuclear localization protein that is widely expressed in many developmental stages and organs. However, the function of SEUSS has not been reported in wood.....»»
New Trials Aim to Restore Hearing in Deaf Children—With Gene Therapy
For the first time, researchers are testing an approach that involves replacing a mutated gene in the inner ears of children with severe hearing loss......»»
Study shows maternal microbiota can affect fetal development
In a Finnish study, significant differences in the gene activity of the fetal intestine, brain and placenta were identified, depending on the microbes in the mother's body and the compounds produced by them. The findings indicate that maternal microb.....»»
Researchers develop novel data representation for transcription factor-binding sequences
The diverse characteristics of the human body's various cells are reflected in their gene expression patterns. The regulation of such gene expression is based on transcription factors that bind to specific sequences in the genome......»»
Thai government pledges action as Bangkok pollution spikes
Thai officials on Friday promised action to address a spike in air pollution that came before the normal peak of seasonal haze, but environmental activists accused authorities of hot air......»»
