Changes in 300 genes could contribute to the maternal behaviour of mice
A research team from the University of Valencia and the Jaume I University of Castellón shows an increase in the expression of 197 genes in mother mice, and a decrease of 99, when compared with virgin females in contact with offspring. These results.....»»
Accessing the bronze tomato"s enhanced antioxidant and health properties through metabolic engineering
The Bronze tomato, a product of metabolic engineering, produces high levels of polyphenol due to the over-expression of genes such as VvStSy, AmDel/Rosea1, and AtMYB12. This modification, part of broader efforts to enhance plant nutritional value thr.....»»
Researchers engineer in vivo delivery system for prime editing, partially restoring vision in mice
Prime editing, a versatile form of gene editing that can correct most known disease-causing genetic mutations, now has a new vehicle to deliver its machinery into cells in living animals......»»
Exploring how antibiotic-resistant bacteria become aggressive
Some strains of antibiotic-resistant bacteria that have recently acquired disease-enhancing genes may not behave as aggressively as expected, according to a Northwestern Medicine study recently published in Nature Communications......»»
When bad cells go good: Harnessing cellular cannibalism for cancer treatment
Scientists have solved a cellular murder mystery nearly 25 years after the case went cold. Following a trail of evidence from fruit flies to mice to humans revealed that cannibalistic cells likely cause a rare human immunodeficiency. Now the discover.....»»
Big evolutionary change tied to lots of small differences
Lots of genes changed as a species of snail went from laying eggs to live births. Enlarge / An example of a Littorina species, the common periwinkle. (credit: Bjoern Wylezich) The version of evolution proposed by Charles.....»»
New roles for autophagy genes in cellular waste management and aging
Autophagy, which declines with age, may hold more mysteries than researchers previously suspected. In the January 4th issue of Nature Aging, it was noted that scientists from the Buck Institute, Sanford Burnham Prebys and Rutgers University have unco.....»»
Genetic variants underlying male bisexual behavior, risk-taking linked to more children, study suggests
Because same-sex sexual behavior does not result in offspring, evolutionary biologists have long wondered how the genes associated with this behavior have persisted in the human genome, and whether they will remain in the future......»»
Evolution is not as random as previously thought, finds new study
A new study has found that evolution is not as unpredictable as previously thought, which could allow scientists to explore which genes could be useful to tackle real-world issues such as antibiotic resistance, disease, and climate change......»»
Cracking the secrets of virus "uncoating" may help fight infections
Influenza and other viruses pack their genetic material into a protein shell, which must be disassembled for the viruses to efficiently replicate. But how viruses "uncoat" their genes remains largely unknown. Now, Friedrich Miescher Institute researc.....»»
Novel switch turns genes on/off on cue, a promising step toward safer gene therapy
Just like a doctor adjusts the dose of a medication to the patient's needs, the expression of therapeutic genes, those modified in a person to treat or cure a disease via gene therapy, also needs to be maintained within a therapeutic window. Staying.....»»
Researchers find large diversity of protists in the Parabasalia phylum in both mice and humans
A team of pathologists, geneticists, immunologists and engineers at the Stanford University School of Medicine, has found a previously unrecognized diversity of protists in the Parabasalia phylum in both mice and humans. In their paper published on t.....»»
"What"s on today"s menu?": Why it"s important to study the trophic behavior of local predators
Trophic ecology is the study of the food chain. On Tenerife in the Canary Islands, feral cats feast chiefly on rabbits, mice, rats, and native birds and reptiles. But new research shows that since 1986, the island's wild cats have experienced a signi.....»»
EVs contribute to delayed vehicle launches
In 2023, 34 percent of all vehicle launches experienced production delays, compared with 5 percent in 2018, said PwC......»»
Antarctic octopus DNA reveals ice sheet collapse closer than thought
Scientists investigating how Antarctica's ice sheets retreated in the deep past have turned to an innovative approach: studying the genes of octopuses that live in its chilly waters......»»
Examining the relationship between the rate of wound healing, the circadian rhythm and cilium length
Nearly every organism on Earth follows a natural circadian rhythm that is coded by your cell's clock genes, which do exactly as you suspect from the name: regulate your body's rhythm on a 24-hour basis......»»
Team discovers relationship between DNA replication timing and how genes fold into 3D structures inside cell nucleus
The intricate process of duplicating genetic information, referred to as DNA replication, lies at the heart of the transmission of life from one cell to another and from one organism to the next. This happens by not just copying the genetic informati.....»»
Expansin genes shown to drive heteroblastic leaves in Ceratopteris chingii
Heteroblasty is a developmental trajectory event in which plants undergo rapid ontogenetic changes in multiple traits, as exemplified by the transition from distinct juvenile to adult leaves. Heteroblastic leaves allow plants to adapt to environmenta.....»»
Human brain cells put much more energy into signaling
Signaling molecules help modulate the brain's overall activity. Enlarge (credit: Westend61) Indian elephants have larger brains than we do (obviously). Mice have a higher brain-to-body mass ratio, and long-finned pilot w.....»»
A bacterial toolkit for colonizing plants
Using a novel experimental approach, Max Planck researchers have discovered a core set of genes required by commensal bacteria to colonize their plant hosts. The findings published in Nature Communications may have broad relevance for understanding h.....»»
Simplifying the way cell proliferation is monitored in mice
Observing cell proliferation in living animals for a long period requires collecting and analyzing animal organs at multiple points in time. This cumbersome process requires an abundance of resources, including animals......»»
