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.....»»
How moonlight fine-tunes animal reproduction
Animals possess circadian clocks, or 24-hour oscillators, to regulate daily behavior. These typically take their cues from the periodic change of sunlight and darkness. However, many animals are also exposed to moonlight, which reoccurs with ~25h per.....»»
Global biogeographical patterns and correlates of floral longevity
The length of time a flower remains open (i.e., from anthesis to flower senescence) is called floral longevity. Floral longevity is one of the most important reproductive traits, as it determines opportunities for pollen dispersal and capture of poll.....»»
Ancient viral elements embedded in human genome are not from fossil retrovirus
Using a next generation sequencing analysis to examine human endogenous retrovirus (HERV) integration sites, researchers from Kumamoto University, the National Institute of Genetics (Japan), and the University of Michigan (U.S.) have discovered that.....»»
A candlelight-like glow from a flexible organic LED
Giving off a comfortable glow, candles set the ambiance for a special dinner or just a quiet evening at home. However, some lighting alternatives, such as electronic candles, give off unwanted blue wavelengths that interfere with the body's circadian.....»»
Monitoring the journey of microplastics through the intestine of a living organism
A UAB research team has managed to track the movement of microplastics during their journey through the intestinal tract of a living organism and illustrate what happens along the way. The study, carried out on Drosophila melanogaster using electron.....»»
Soundfall turns dungeon crawling into a killer dance party
Soundfall takes the rhythm game genre to the next level with an eclectic playlist that works — if you can keep up with the beat......»»
Heart progenitors spontaneously regenerate cardiac muscle via a tight junction "honeycomb" in salamanders
Whether there are endogenous adult heart progenitors that can replenish damaged muscle cells remained controversial. Now researchers at Karolinska Institute in Sweden show that the outermost layer of the heart, called epicardium, acts as a source of.....»»
Tiling mechanisms of the Drosophila compound eye through geometrical tessellation
Tile patterns in which the same shape is laid out without gaps can be seen on castle walls and chess boards in artificial objects, and in insect compound eyes and beehives in biology. Square tiles are common in artificial objects, while hexagonal til.....»»
NeuroMechFly: A digital twin of Drosophila
EPFL scientists have developed a digital model of the fruit fly, Drosophila melanogaster, that realistically simulates the movements of the animal. The twin is a big step towards reverse engineering the neuromechanical control of animal behavior, and.....»»
Chronobiologists identify key circadian clock mechanism in cyanobacteria
Researchers have identified a key mechanism involved with the setting of the circadian clock of cyanobacteria—a model organism for study by chronobiologists due to the organism having one of the earliest circadian systems to evolve, and thus shinin.....»»
Fitbit’s AFib detection is here and it could save your life
FitBits now feature AFib detection which could notify a person that they have an irregular heart rhythm before experiencing severe symptoms......»»
Climate change is altering the seasonal rhythm of plant life-cycle events

Unlocking complex workings of the biological clock
Scientists want to increase their understanding of circadian rhythms, those internal 24-hour biological clock cycles of sleeping and waking that occur in organisms, ranging from humans to plants to fungi to bacteria. A research team has examined the.....»»
Cell-derived therapy may help repair abnormal heart rhythm
Vesicles secreted from human heart cells may repair damaged tissue and prevent lethal heart rhythm disorders, according to a new study......»»
Fitbit"s passive heart rhythm monitoring algorithm gets FDA approval
To be clear, Fitbit already allows users to use its trackers to monitor their hearth rhythm, but it requires them to open up the Fitbit app and manually initiate a check -- an extra step that will be made obsolete. Soon enough, Fitbit devices will be.....»»

Decoding the molecular clock that controls neurogenesis in the visual center of Drosophila
The nervous system is made up of diverse cells that arise from progenitors in a specific time-dependent pattern. In a new study published in Nature Communications, researchers have uncovered the molecular players involved and how the timing is contro.....»»
The fitness of photosynthetic organisms depends on the integrity of their endogenous clocks
Life on Earth runs in 24-hour cycles. From tiny bacteria to human beings, organisms adapt to alterations of day and night. External factors, such as changes in light and temperature, are needed to entrain the clock. Many metabolic processes are contr.....»»
Can an image-based electrocardiographic algorithm improve access to care in remote settings?
Researchers have developed an artificial intelligence (AI)-based model for clinical diagnosis that can use electrocardiogram (ECG) images, regardless of format or layout, to diagnose multiple heart rhythm and conduction disorders......»»
