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.....»»
Relationship between chromosomal instability and senescence revealed in the fly Drosophila
Researchers have revealed the mechanisms by which cells enter senescence because of an imbalance in the number of chromosomes. Chromosomal instability is a common trait in most solid tumors, such as carcinoma, and fully understanding its relationship.....»»
Relationship between chromosomal instability and senescence revealed in Drosophila
Chromosomal instability is a feature of solid tumors such as carcinoma. Likewise, cellular senescence is a process that is highly related to cellular aging and its link to cancer is becoming increasingly clear. Scientists led by ICREA researcher Dr......»»
Hot nights confuse circadian clocks in rice, hurting crop yields
Rising nighttime temperatures are curbing crop yields for rice, and new research moves us closer to understanding why. The study found that warmer nights alter the rice plant's biological schedule, with hundreds of genes being expressed earlier than.....»»
Study shows effectiveness of suppressing female fruit flies
Populations of Drosophila suzukii fruit flies—so-called "spotted-wing Drosophila" that devastate soft-skinned fruit in North America, Europe and parts of South America—could be greatly suppressed with the introduction of genetically modified D. s.....»»
Crosslinker protein helps egg cells develop
A protein helps direct the flow of materials in the Drosophila ovary during the development of egg cells, according to a Northwestern Medicine study published in Current Biology......»»
Star"s death will play a mean pinball with rhythmic planets
Four planets locked in a perfect rhythm around a nearby star are destined to be pinballed around their solar system when their sun eventually dies, according to a new study that peers into its future......»»
Mechanochemical peptide bond formation behind the origins of life
The presence of amino acids on the prebiotic Earth is widely accepted, either coming from endogenous chemical processes or being delivered by extraterrestrial material. On the other hand, plausibly prebiotic pathways to peptides often rely on differe.....»»
Apple"s MagSafe Devices May Affect Pacemakers
The American Heart Association is a research-funding nonprofit. One of its publications, The Journal of the American Heart Association, "has concurred with a previous report by the Heart Rhythm Journal which said close contact with an iPhone 12 affec.....»»
Genetic tricks of the longest-lived animals
By studying long-living animals, researchers hope to pinpoint factors affecting human longevity. Enlarge / Bats, remarkable little things. (credit: Bernd Wolter / EyeEm) Life, for most of us, ends far too soon—hence the effort by biomedical.....»»

Nanoparticles: The complex rhythm of chemistry
Most commercial chemicals are produced using catalysts. Usually, these catalysts consist of tiny metal nanoparticles that are placed on an oxidic support. Similar to a cut diamond, whose surface consists of facets oriented in different directions, a.....»»
Longevity startup Gero AI has a mobile API for quantifying health changes
Sensor data from smartphones and wearables can meaningfully predict an individual’s ‘biological age’ and resilience to stress, according to Gero AI. The ‘longevity’ startup — which condenses its mission to the pith.....»»
Circadian rhythm research could turn early birds into night owls
How body clocks work could lead to science that can turn an early bird into a night owl or vice versa as well as other advances, like helping crops grow all year long......»»
Fish oil supplements and heart rhythm disorder: New analysis
Omega-3 supplements are associated with an increased likelihood of developing atrial fibrillation in people with high blood lipids, according to a new analysis......»»
Anesthesia doesn"t simply turn off the brain, it changes its rhythms
Simultaneous measurement of neural rhythms and spikes across five brain areas in animals reveals how propofol induces unconsciousness. Slow rhythm signature can guide anesthesiologists to improve patient care......»»
Exploit plants" ability to tell the time to make food production more sustainable: study
Cambridge plant scientists say circadian clock genes, which enable plants to measure daily and seasonal rhythms, should be targeted in agriculture and crop breeding for higher yields and more sustainable farming......»»
Methane release rapidly increases in the wake of the melting ice sheets
Ice ages are not that easy to define. It may sound intuitive that an ice age represents a frozen planet, but the truth is often more nuanced than that. An ice age has constant glaciations and deglaciations, with ice sheets pulsating with the rhythm o.....»»
New method preserves viable fruit fly embryos in liquid nitrogen
Cryopreservation, or the long-term storage of biomaterials at ultralow temperatures, has been used across cell types and species. However, until now, the practical cryopreservation of the fruit fly (Drosophila melanogaster)—which is crucial to gene.....»»
