Exploring Darwin"s longstanding interest in biological rhythms
A close reading of Darwin's work suggests a deep interest in cyclical events. Rhythmic phenomena in nature—today the subjects of the field of chronobiology—have been studied since at least the 18th century. In a perspective, Tiago Gomes de Andrad.....»»
Dissecting caspase-2-mediated cell death: From intrinsic PIDDosome activation to chemical modulation
Caspase-2, an initiator caspase, plays a critical role in programmed cell death in response to certain cellular stresses. Its activation is facilitated by the PIDDosome, a multi-protein complex that assembles under conditions of genotoxic stress. Des.....»»
Discovery of a hidden epigenetic clock in mitochondria reveals a "lifespan limit line"
Building on their work on epigenetics of aging and transposable elements, researchers Dr. Ádám Sturm and Dr. Tibor Vellai from Eötvös Loránd University have made another advance in understanding the molecular mechanisms of aging. Their latest st.....»»
Unlocking crop yield potential: New modeling approach for sustainable agriculture
Predicting crop yields is a significant challenge in modern agriculture, especially under fluctuating environmental conditions. With the escalating demand for sustainable food production, understanding the complex interplay between environmental fact.....»»
Hybrid imaging approach reveals microbes in 3D
Caltech researchers have developed a new method to create three-dimensional images of complex communities of bacteria and plant roots. The technology synthesizes two traditional methods of imaging: visualizing microbes with fluorescence and a noninva.....»»
Study highlights new advancements to simulate multiscale coastal processes
Simulating flooding where rivers meet the ocean is challenging because existing Earth system models struggle to capture the complex interactions between river flows, ocean tides, and storm surges......»»
Innovative field experiments shed light on biological clocks in nature
Much of what we know about plant circadian rhythms is the result of laboratory experiments where inputs such as light and temperature can be tightly controlled......»»
Researchers synthesize molecular aggregates for solar energy applications
No molecule stands alone—they need others, at least when it comes to being able to display useful photophysical, electronic, and chemical properties. When individual molecules combine into an aggregate, or a complex of two or more molecules, they b.....»»
New approach for profiling complex dynamics at the single-molecule level
A team of researchers led by Professor Sebastian Deindl at Uppsala University has developed a pioneering method that vastly improves the ability to observe and analyze complex biological processes at the single-molecule level. Their work is published.....»»
A small molecular glue that increases P53 level and suppresses tumor growth in vivo
Molecular glues are typically small chemical molecules that act on the interface between the target protein and the degradation machinery to trigger ternary complex formation. Identification of molecular glues is challenging, and there has been a lac.....»»
Here are 7 widgets that make StandBy Mode worth using [video]
StandBy Mode was introduced to us with the release of iOS 17. It gave the iPhone this passive but dynamic viewing mode when charging and in landscape mode. It can be used as a clock, to see the weather, as a hub for the Home app, or to help avoid dis.....»»
