Endogenous ceramide phosphoethanolamine modulates circadian rhythm and longevity in Drosophila
The circadian clock entrains rhythmic patterns in behavioral and physiological processes to temporally coordinate systemic metabolism with the rising and setting of the sun. In previous investigation on human subjects, sphingomyelins (SMs) exhibited.....»»
Team modulates electronic state of single-atom catalysts by CO molecular decoration for efficient methane conversion
Direct methane conversion has advantages such as low energy consumption, fewer processes, and better economics. However, it is difficult to activate methane at room temperature due to the high dissociation energy of C-H bonds of methane. Additionally.....»»
Post-menopausal whales may help solve the mystery of female longevity
Although life can seem to go whizzing by, humans are actually weirdly long-lived animals. A new study helps explain why: menopause......»»
Researchers identify key regulators underlying regeneration in Drosophila
Some animals possess the remarkable ability to regenerate lost structures, exemplified by a lizard regrowing its tail. However, this regenerative process must be tightly regulated by the body to ensure proper tissue organization and to prevent abnorm.....»»
‘Música’ trailer encapsulates the main character"s torment
Synesthesia ahoy in YouTuber Rudy Mancuso's SXSW film. It’s hard to encapsulate a whole movie in a trailer without ruining it, but whoever edited the Música trailer infuses the whole thing with the rhythm underpinning its main char.....»»
Live imaging reveals key cell dynamics in 3D organ formation in Drosophila
Animal development requires successive changes in cell and tissue structures. To form complex 3D organs, cell shapes must adapt to support tissue morphogenesis. However, our understanding of how cellular structure changes are coupled with dynamic tis.....»»
Chromatin accessibility: A new avenue for gene editing
In a study recently published in Nature Genetics, researchers from Nano Life Science Institute (WPI-NanoLSI), Kanazawa University explore chromatin accessibility, i.e., endogenous access pathways to the genomic DNA, and its use as a tool for gene edi.....»»
The modeling and simulation of self-organized intracellular twisters in the Drosophila oocyte
Cytoplasmic streaming is the large-scale motion of cytoplasm (i.e., gelatinous liquid inside cells) inside a living cell. This flow, known to regulate various intracellular processes, can vary greatly between different cell types at different stages.....»»
Humans are living longer than ever no matter where they come from
Disease outbreaks and human conflicts help dictate regional differences in longevity. Enlarge (credit: Catherine Falls Commercial) Most of us want to stay on this planet as long as possible. While there are still differe.....»»
A cholesterol precursor mediates sensitivity to cell death by ferroptosis
A team of scientists from the University of Ottawa and researchers from other universities and research centers around the world has discovered that 7-dehydrocholesterol (7-DHC) is an endogenous suppressor of ferroptosis, which could have important i.....»»
Zebrafish usp3 loss found to promote hypoxic tolerance
Oxygen is an essential element for survival. Ocean warming, circadian rhythm, eutrophication, high-density aquaculture, power failures and long-distance live animal transportation can all lead to low oxygen levels in water. This reduction in oxygen c.....»»
Good sleep could mean you live up to 4.7 years longer, study finds
Research shows consistent sleep might improve your longevity – here's how to go about getting it......»»
For this beetle, "date night" comes every other day: The 48-hour cycle of the large black chafer beetle
Life on Earth runs on a 24-hour cycle as the planet turns. Animals and plants have built-in circadian clocks that synchronize metabolism and behavior to this daily cycle. But one beetle is out of sync with the rest of nature......»»
Unraveling the role of supersulfides in regulating mitochondrial function and longevity
Supersulfides are gaining prominence for their occurrence as low-molecular-weight thiols or persulfidated cysteine residues, observed more frequently in both prokaryotic and eukaryotic cells. These compounds, which are characterized by sulfur–sulfu.....»»
From stalling to falling: Life expectancy decline hits UK economy and workforce
Life expectancy for people aged over 50 has started to fall, according to new research from Bayes Business School (formerly Cass) and the International Longevity Center (ILC)......»»
Viruses as important factors driving the diel dynamics of marine bacterioplankton
The diel cycle is one of the most common periodic patterns in marine ecosystems. Previously, the diel rhythm changes of marine bacterioplankton have often been attributed to factors like bacterial light-dependent physiological mechanisms or their int.....»»
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......»»
Challenging assumptions: The 8.5-year rhythm of Earth"s inner core
Researchers from China have confirmed the existence of an approximately 8.5-year Inner Core Wobble (ICW) in both polar motion and length-of-day variations, revealing a static tilt of about 0.17 degrees between the Earth's inner core and mantle, chall.....»»
Migratory songbird study finds link between white tail spots and longevity
A new study of a migratory songbird shows that individuals with average-sized white tail spots—a trait that is critical to successful foraging—live longer than individuals with more extreme amounts of white in the tail......»»
Bear genes show circadian rhythms even during hibernation
The internal clocks of grizzly bears appear to keep ticking through hibernation, according to a genetic study. This persistence highlights the strong role of circadian rhythms in the metabolism of many organisms including humans......»»
Apple Watch heart rate notifications saves Atlanta artist
The Apple Watch helped an artist in Atlanta discover an irregular heart rhythm, leading to a hospital visit and surgery that saved his life.Artist Bob Ichter, 65, is a regular cyclist of the BeltLine, and considered himself to be more than fit enough.....»»
