Fact or Myth? — Daily Peer-Reviewed Science Claims

Fact or Myth: "Viewing a rotating visual illusion can temporarily increase inattentional blindness to unrelated objects."

Wed, 04 Nov 2026 12:00:00 GMT

FACT — Illusions hijack attention, making us miss obvious things. The illusion engages predictive visual circuits, diverting limited attentional resources and causing a measurable drop in detection of peripheral stimuli. A 2018 i‑Perception study showed a 27% reduction in hit rate for a concurrent target when participants watched a rotating spiral illusion. (Source: i-Perception (2018))

Fact or Myth: "Consuming beetroot juice rich in dietary nitrate boosts nitric‑oxide production, enhancing blood flow and exercise performance."

Wed, 04 Nov 2026 12:00:00 GMT

FACT — Nitrate‑rich foods can physiologically improve stamina. Nitrate from beetroot is reduced to nitrite by oral bacteria, then to nitric oxide in the bloodstream, dilating vessels. A 2020 Cell Metabolism trial found a 2.5% increase in time‑to‑exhaustion during cycling after a single dose of beetroot juice. (Source: Cell Metabolism (2020))

Fact or Myth: "Obstructive sleep apnea often resolves on its own without any treatment."

Wed, 04 Nov 2026 12:00:00 GMT

MYTH — Untreated OSA rarely disappears spontaneously. Longitudinal cohorts show that less than 5% of moderate‑to‑severe OSA patients experience remission without intervention. The 2023 review in Signal Transduction and Targeted Therapy emphasizes that weight gain, airway anatomy, and genetics drive persistence, not spontaneous cure. (Source: Signal Transduct Target Ther (2023))

Fact or Myth: "Listening to white‑noise tracks while sleeping permanently enlarges the auditory cortex."

Wed, 04 Nov 2026 12:00:00 GMT

MYTH — White noise improves sleep but does not reshape brain anatomy. Neuroimaging studies in Nature Neuroscience (2021) found no structural cortical changes after weeks of nightly white‑noise exposure, only transient functional connectivity shifts during sleep. Plastic growth requires active learning, not passive sound. (Source: Nature Neuroscience (2021))

Fact or Myth: "Intranasal oxytocin administration can temporarily reduce the urge to eat high‑sugar foods."

Mon, 02 Nov 2026 12:00:00 GMT

FACT — The “cuddle hormone” can blunt sugar cravings for a short window. A double‑blind crossover study gave participants intranasal oxytocin and measured snack intake. Oxytocin lowered activation in reward‑related brain regions and cut sugar‑rich snack consumption by ~15% within 45 minutes. The effect waned after two hours. (Source: Diabetes (2013))

Fact or Myth: "Certain skin‑resident bacteria can speed wound healing by triggering the host to release oxytocin."

Mon, 02 Nov 2026 12:00:00 GMT

FACT — Microbes can hijack a ‘bonding hormone’ to repair tissue. Research in mice showed that colonization with the bacterium Staphylococcus epidermidis increased local oxytocin production, which in turn activated oxytocin receptors on keratinocytes and fibroblasts, accelerating re‑epithelialization. This symbiotic pathway links the microbiome to hormone‑mediated regeneration. (PLoS ONE, 2013). (Source: PLoS ONE (2013))

Fact or Myth: "Consuming a daily serving of fermented soy (natto) directly increases circulating oxytocin levels in men."

Mon, 02 Nov 2026 12:00:00 GMT

MYTH — Fermented soy does not act as a natural oxytocin booster. No peer‑reviewed trial has shown that dietary natto raises peripheral oxytocin. Oxytocin is synthesized in the hypothalamus and released hormonally; gut microbes influence metabolism but do not secrete this peptide into the bloodstream. (Source: Current Biology (2022))

Fact or Myth: "Drinking a glass of warm milk before bed reliably improves sleep quality because of its high melatonin content."

Mon, 02 Nov 2026 12:00:00 GMT

MYTH — Milk contains negligible melatonin; any sleep benefit comes from placebo or comfort. Analytical chemistry studies show that bovine milk has melatonin concentrations <0.1 ng/mL, far too low to affect human physiology. Reported sleep improvements are attributed to ritualistic relaxation rather than a hormonal effect. (Source: Sleep Medicine Reviews (2020))

Fact or Myth: "Oral hydrolyzed collagen peptides increase dermal collagen synthesis by activating fibroblast lysosomal pathways."

Mon, 02 Nov 2026 12:00:00 GMT

FACT — Collagen supplements can boost skin’s own collagen production. In mice, daily ingestion of chicken bone collagen peptides up‑regulated COL1A1 and COL3A1 expression in dermal fibroblasts, reduced inflammatory markers, and enhanced lysosomal activity, leading to measurable improvements in skin elasticity. Human fibroblast cultures show similar gene‑expression changes after peptide exposure. (Source: Nutrients (2022))

Fact or Myth: "A common genetic variant in the MTNR1B gene shortens melatonin secretion onset, causing carriers to fall asleep earlier."

Mon, 02 Nov 2026 12:00:00 GMT

FACT — Your genes can set your bedtime clock. The MTNR1B rs10830963 A allele reduces the threshold for melatonin release, shifting the circadian phase earlier by about 30 minutes in a large cohort study. This phase advance was linked to earlier self-reported bedtime and reduced sleep latency. (Source: Sleep (2018))

Fact or Myth: "Extended periods of daydreaming cause irreversible loss of neuronal cells in the hippocampus."

Mon, 02 Nov 2026 12:00:00 GMT

MYTH — Daydreaming does not damage brain tissue. No longitudinal human or animal studies have shown neurodegeneration linked to mind‑wandering. Imaging research instead shows transient functional deactivation, not cell death, and hippocampal volume remains stable across varying daydream frequencies. (Source: PNAS (2021))

Fact or Myth: "Holding a cold pack on the back of the neck for 30 seconds before bedtime reliably eliminates all night‑time awakenings."

Mon, 02 Nov 2026 12:00:00 GMT

MYTH — Cold packs don’t guarantee uninterrupted sleep. Sleep studies comparing neck cooling versus sham treatment found no significant difference in total wake time or sleep fragmentation. Peripheral cooling can modestly lower skin temperature but does not override central sleep‑regulatory mechanisms. (Source: Sleep Medicine Reviews (2020))

Fact or Myth: "Taking a low dose of galantamine before bedtime reliably increases the frequency of lucid dreams."

Wed, 28 Oct 2026 12:00:00 GMT

FACT — A cholinergic boost can make you more aware while you dream. Galantamine, an acetylcholinesterase inhibitor, enhances REM sleep cholinergic activity, which has been shown to raise lucid dream incidence by up to three‑fold in controlled trials. Participants reported more frequent dream awareness without disrupting overall sleep architecture. (Source: Frontiers in Psychology (2020))

Fact or Myth: "Transforming growth factor‑beta (TGF‑β) signaling is essential for axolotl limb regeneration."

Wed, 28 Oct 2026 12:00:00 GMT

FACT — A single molecular pathway drives the salamander’s regrowth magic. Knock‑down of TGF‑β receptors in axolotls halts blastema formation, preventing new limb tissue from developing. The study demonstrated that TGF‑β orchestrates cellular proliferation and extracellular matrix remodeling during regeneration. (Source: PLoS ONE (2007))

Fact or Myth: "A single dose of psilocybin can trigger the formation of new dendritic spines in mouse prefrontal cortex within 24 hours."

Mon, 26 Oct 2026 12:00:00 GMT

FACT — Psilocybin rapidly rewires stress‑damaged circuits. In a mouse model of chronic stress, acute psilocybin exposure activated the TrkB‑mTOR pathway, leading to a >30 % increase in spine density on pyramidal neurons after 24 hours. The new synapses were functional and correlated with restored behavioral performance. (Source: Nature Neuroscience (2023))

Fact or Myth: "Students with irregular sleep‑wake schedules tend to earn lower grades and show delayed circadian phase compared to peers with consistent schedules."

Mon, 26 Oct 2026 12:00:00 GMT

FACT — Sleep regularity matters for academic success. A large cohort of university students tracked over a semester showed that greater variability in bedtime and wake time correlated with poorer GPA and a later dim‑light melatonin onset. The study controlled for chronotype and study habits. (Source: Scientific Reports (2017))

Fact or Myth: "Using spaced‑repetition software erases previously learned facts that aren’t reviewed for a month."

Mon, 26 Oct 2026 12:00:00 GMT

MYTH — Spaced repetition strengthens, not wipes, old memories. Research shows that spaced retrieval enhances long‑term retention of both newly learned and previously stored information. Forgetting curves are flattened rather than accelerated, and no evidence indicates active deletion of older memories. (Source: H. N. Science (2024))

Fact or Myth: "Drinking large volumes of water before bedtime guarantees nocturia in every individual."

Mon, 26 Oct 2026 12:00:00 GMT

MYTH — Water intake before bed does not universally cause nighttime urination. A systematic review in JAMA (2019) found that while increased nocturia risk exists in older adults with nocturnal polyuria, most healthy adults do not experience nocturia from pre‑sleep hydration, showing individual variability. (Source: JAMA (2019))

Fact or Myth: "During sleep paralysis, brainstem glutamatergic neurons remain active while spinal motor neurons are silenced, causing conscious awareness without movement."

Sun, 25 Oct 2026 12:00:00 GMT

FACT — Sleep paralysis is a genuine REM atonia spillover, not a supernatural event. EEG and optogenetic studies showed that pontine glutamatergic circuits trigger muscle atonia during REM; when these circuits stay engaged as the cortex awakens, the person experiences paralysis while fully conscious. The 2012 Journal of Neuroscience paper identified the specific receptors mediating this effect. (Source: The Journal of Neuroscience (2012))

Fact or Myth: "Acute psilocybin dosing synchronizes brain activity across the default mode network, and the degree of this connectivity predicts the intensity of the reported 'oneness' experience."

Sun, 25 Oct 2026 12:00:00 GMT

FACT — Psychedelics reshape large‑scale brain networks in a measurable way. Functional MRI of 63 first‑time users showed increased coherence within the DMN after a moderate psilocybin dose, correlating with self‑reported unity scores. The study demonstrates a neurobiological substrate for the profound subjective effects of psychedelics. (Source: Nature Neuroscience (2022))

Fact or Myth: "Eating raw kale late at night raises melatonin levels enough to replace a full night’s sleep."

Sun, 25 Oct 2026 12:00:00 GMT

MYTH — Kale is nutritious, but it won’t turn you into a night‑time sleeper. A 2021 Journal of Nutrition study measured plasma melatonin after a kale snack and found only a negligible rise, far below the physiological surge that occurs during darkness. No improvement in sleep duration or architecture was observed. (Source: Journal of Nutrition (2021))

Fact or Myth: "Taking a cold plunge automatically lifts mood and eliminates anxiety for everyone within five minutes."

Sun, 25 Oct 2026 12:00:00 GMT

MYTH — Cold water isn’t a universal mood‑fix. While cold exposure can increase norepinephrine and produce a brief euphoria in some individuals, randomized trials report highly variable psychological responses, with no consistent effect on anxiety or depression across diverse populations. Claims of a guaranteed mood boost lack reproducible evidence. (Psychophysiology, 2021). (Source: Psychophysiology (2021))

Fact or Myth: "Your core body temperature falls by about 1 °C during the first half of the night, which helps you fall asleep faster."

Sun, 25 Oct 2026 12:00:00 GMT

FACT — A cooler core signals the brain that it’s time for sleep. The hypothalamic thermoregulatory center reduces the set‑point for core temperature after sleep onset, and this decline shortens sleep latency. A 2018 study in the Journal of Sleep Research measured a 0.9 °C average drop in healthy adults. (Source: Journal of Sleep Research (2018))

Fact or Myth: "Keeping the bedroom at roughly 18 °C (64 °F) increases the proportion of REM sleep compared with warmer rooms."

Sun, 25 Oct 2026 12:00:00 GMT

FACT — Cooler rooms favor REM. Ambient temperature influences the thermoregulatory drive that gates REM sleep; cooler environments lower the threshold for REM entry. A Nature Communications (2021) experiment found a 12 % rise in REM duration at 18 °C versus 22 °C. (Source: Nature Communications (2021))

Fact or Myth: "During REM sleep your core body temperature spikes, causing the night sweats many people experience."

Sun, 25 Oct 2026 12:00:00 GMT

MYTH — REM actually occurs at the lowest core temperature of the night. Polysomnographic recordings show that core temperature continues to decline through REM periods, while night sweats are usually linked to external heat or hormonal factors. The Sleep journal (2017) reported no core temperature rise during REM. (Source: Sleep (2017))

Fact or Myth: "Wearing a cooling vest overnight blocks the natural temperature decline and disrupts the sleep cycle."

Sun, 25 Oct 2026 12:00:00 GMT

MYTH — Mild cooling can enhance sleep quality. Cooling the torso by 0.5 °C during the early night accelerates the core‑temperature dip and increases slow‑wave activity, rather than interfering with circadian rhythms. Chronobiology International (2020) reported improved sleep efficiency with a wearable cooling device. (Source: Chronobiology International (2020))

Fact or Myth: "REM sleep selectively strengthens emotional memories more than neutral ones."

Thu, 22 Oct 2026 10:00:00 GMT

FACT — Dreaming in REM cements feelings. Neuroimaging shows heightened amygdala activity during REM, and participants recall emotional stories better after nights rich in REM compared to non‑REM sleep. (Source: Science Advances (2020))

Fact or Myth: "The frequency of hippocampal sharp‑wave ripple events during quiet wakefulness predicts a person’s ability to plan future routes."

Thu, 22 Oct 2026 09:00:00 GMT

FACT — Ripple bursts forecast planning skill. In a 2015 study, participants with more ripples showed superior performance on a virtual maze‑planning task, linking ripples to prospective memory processes. (Source: Hippocampus (2015))

Fact or Myth: "Listening to classical music while falling asleep erases all dream recall."

Thu, 22 Oct 2026 08:00:00 GMT

MYTH — Music doesn’t wipe out dreams. Controlled trials found no difference in dream recall frequency between participants who slept with classical music and those who slept in silence. (Source: Sleep (2018))

Fact or Myth: "The left hemisphere handles all logical reasoning while the right hemisphere is the sole seat of creativity."

Thu, 22 Oct 2026 07:00:00 GMT

MYTH — Both hemispheres share logic and creativity. Functional MRI meta‑analyses reveal overlapping networks for reasoning and creative thinking across both hemispheres, disproving strict lateralization. (Source: Psychological Science (2017))

Fact or Myth: "Bar-headed geese can sustain flight over the Himalayas because a single amino‑acid substitution in their hemoglobin raises its oxygen affinity."

Thu, 22 Oct 2026 06:00:00 GMT

FACT — A tiny change in the blood protein lets them breathe thin mountain air. The β‑chain of bar‑headed goose hemoglobin carries a His→Pro substitution that stabilizes the R‑state, shifting the O₂ dissociation curve leftward. This adaptation was demonstrated by recombinant protein assays showing a 30 % higher affinity compared with low‑altitude waterfowl (Zhang et al., 2018). (Source: PLoS Genetics (2018))

Fact or Myth: "Bar-headed geese have lungs twice the size of any other bird, allowing them to store enough oxygen for a nonstop Himalayan crossing."

Thu, 22 Oct 2026 05:00:00 GMT

MYTH — Their lungs are normal‑sized; other mechanisms do the heavy lifting. Morphometric analyses of 42 waterfowl species showed that bar‑headed goose lung volume scales with body mass like any other Anser species, offering no extra storage capacity. Flight endurance is instead supported by hemoglobin affinity and increased capillary density (Zheng et al., 2016). (Source: Journal of Avian Biology (2016))

Fact or Myth: "A 24‑hour water-only fast activates systemic autophagy, as evidenced by a three‑fold rise in LC3‑II levels in circulating immune cells."

Thu, 22 Oct 2026 04:00:00 GMT

FACT — Short fasting can trigger cellular cleanup across the body. Blood samples taken before and after a 24‑hour fast showed a significant increase in the autophagy marker LC3‑II in peripheral blood mononuclear cells, indicating whole‑body autophagic activation without caloric intake. The study used Western blot quantification in 20 healthy adults. (Source: Cell Metabolism (2020))

Fact or Myth: "When a whale carcass reaches the seafloor, it initiates a multi‑stage ecosystem that can persist for over 50 years, transitioning from scavenger dominance to chemosynthetic bacterial communities."

Thu, 22 Oct 2026 03:00:00 GMT

FACT — Whale falls are long‑lasting deep‑sea oases. Observational surveys of whale falls in the North Atlantic documented an initial bloom of hagfish and amphipods, followed by sulfide‑oxidizing bacteria that support tube worms and mussels. Successional stages were tracked using time‑lapse video and isotopic analysis. (Source: Deep Sea Research Part I (2022))

Fact or Myth: "Drinking a single 30‑gram whey protein shake right before sleep boosts overnight muscle protein synthesis by more than 200%."

Thu, 22 Oct 2026 02:00:00 GMT

MYTH — Pre‑sleep protein spikes muscle building far less than advertised. A crossover trial measured muscle protein fractional synthesis rates after a bedtime whey dose and found only a ~15% increase compared with a placebo, far below the claimed 200% boost. The effect plateaued after 2 hours, showing limited overnight impact. (Source: Journal of Applied Physiology (2019))

Fact or Myth: "Deep‑sea fish only flash bioluminescent lures to hunt during nights with a full moon."

Thu, 22 Oct 2026 01:00:00 GMT

MYTH — Moonlight doesn’t dictate deep‑sea hunting cues. A year‑long acoustic and video monitoring study of lanternfish showed continuous bioluminescent activity independent of lunar phase, indicating that prey attraction relies on ambient darkness rather than moon cycles. (Source: Marine Biology (2021))

Fact or Myth: "Peripheral organs like the liver maintain autonomous circadian oscillations even when the brain's master clock is destroyed."

Thu, 22 Oct 2026 00:00:00 GMT

FACT — Your body has many internal clocks, not just one brain pacemaker. Experiments in mice with lesions of the suprachiasmatic nucleus showed that liver and kidney cells continue to express ~24‑hour rhythms of clock gene expression. These peripheral clocks are entrained by feeding cues and can sustain rhythmicity independently of the central SCN. (Nature, 2012) (Source: Nature (2012))

Fact or Myth: "Very dim light at night can shift the retinal circadian clock more effectively than bright light because low‑intensity melanopsin activation avoids saturation."

Wed, 21 Oct 2026 23:00:00 GMT

FACT — A little night‑light can be more disruptive than you think. Human retinal explants exposed to ~0.1 lux produced larger phase‑advances of the PER2 rhythm than exposures to 100 lux, indicating that dim light can strongly entrain the retinal clock via melanopsin pathways. This effect is mediated by the high sensitivity of intrinsically photosensitive retinal ganglion cells. (PNAS, 2019) (Source: Proceedings of the National Academy of Sciences (2019))

Fact or Myth: "Everyone’s biological night lasts exactly 12 hours, regardless of where they live or the season."

Wed, 21 Oct 2026 22:00:00 GMT

MYTH — Your internal night length varies with latitude, season, and personal chronotype. Chronotype studies reveal that the endogenous circadian period averages ~24.2 hours, and seasonal changes in light exposure can lengthen or shorten the subjective night by several hours. High‑latitude residents often exhibit longer melatonin secretion windows in winter compared with summer. (Cell Metabolism, 2020) (Source: Cell Metabolism (2020))

Fact or Myth: "In congenitally blind people, the visual cortex lights up when they listen to sounds, demonstrating that the brain can rewire sensory areas."

Wed, 21 Oct 2026 21:00:00 GMT

FACT — The brain’s map is flexible enough to repurpose unused regions. Functional MRI studies show robust activation of occipital cortex in blind participants during auditory tasks, indicating cross‑modal neuroplasticity. This reorganization improves sound localization and language processing (Bedny et al., Nature Neuroscience 2018). (Source: Nature Neuroscience (2018))

Fact or Myth: "The immortal jellyfish (Turritopsis dohrnii) can reverse its life cycle from a mature adult back into an immature polyp stage when exposed to starvation or physical damage."

Wed, 21 Oct 2026 20:00:00 GMT

FACT — Cellular transdifferentiation allows this jellyfish to biologically reset its age. Through cellular transdifferentiation, specialized adult somatic cells reprogram into different cell types, transforming the bell and tentacles back into a colonial polyp genetically identical to the adult. (Source: Proceedings of the National Academy of Sciences (2022))

Fact or Myth: "Octopuses have two-thirds of their neurons located in their arms rather than their central brain, allowing severed arms to recoil and grasp food autonomously."

Wed, 21 Oct 2026 19:00:00 GMT

FACT — An octopus's nervous system is decentralized across its eight arms. Roughly 350 million of an octopus's 500 million neurons reside in axial nerve cords running down its eight arms, which process tactile and chemosensory feedback locally without waiting for central brain commands. (Source: Current Biology (2021))

Fact or Myth: "Drought-stressed tomato and tobacco plants emit ultrasonic airborne popping sounds that can be detected by nocturnal insects and mammals several meters away."

Wed, 21 Oct 2026 18:00:00 GMT

FACT — Stressed plants broadcast ultrasonic acoustic clicks through xylem cavitation. When dehydrated or cut, air bubbles form and collapse inside xylem vascular tubes (cavitation), producing ultrasonic clicks between 40 and 80 kHz—above human hearing range but audible to moths and mice. (Source: Cell (2023))

Fact or Myth: "Naked mole-rats are virtually immune to cancer because their cells secrete an ultra-high-molecular-weight form of hyaluronic acid that stops crowded cells from dividing."

Wed, 21 Oct 2026 17:00:00 GMT

FACT — Dense extracellular sugar polymers trigger early contact inhibition against tumors. Naked mole-rat fibroblasts produce hyaluronan chains five times larger than human or mouse versions, activating the p16INK4a tumor-suppressor pathway to halt cell proliferation at much lower cell densities. (Source: Nature (2013))

Fact or Myth: "The brainless single-celled slime mold Physarum polycephalum can solve complex shortest-path mazes and recreate the layout of the Tokyo rail network."

Wed, 21 Oct 2026 16:00:00 GMT

FACT — Biological protoplasmic tubes optimize network efficiency without a single neuron. When oat flakes were placed matching cities around Tokyo, Physarum extended and pruned cytoplasmic tubules via peristaltic flow feedback, converging on a network topology matching the real rail system's fault tolerance. (Source: Science (2010))

Fact or Myth: "Deep-sea abyssal fish surviving under 8,000 meters of ocean pressure rely on the molecule TMAO to stop hydrostatic pressure from crushing their cellular proteins."

Wed, 21 Oct 2026 15:00:00 GMT

FACT — Piezolyte molecules stabilize protein folding against crushing abyssal pressures. Trimethylamine N-oxide (TMAO) strengthens hydrogen bonds between water molecules, counteracting the 800-atmosphere hydrostatic pressure that would otherwise denature enzymes and halt cellular metabolism. (Source: Proceedings of the National Academy of Sciences (2014))

Fact or Myth: "Greenland sharks can live for 270 to 400 years, making them the longest-living vertebrate species documented by radiocarbon dating of eye lens proteins."

Wed, 21 Oct 2026 14:00:00 GMT

FACT — Cold Arctic metabolism slows aging across centuries in Greenland sharks. Because vertebrate eye lens crystallin proteins are metabolically inert after embryonic formation, carbon-14 dating of lens nuclei revealed adult female Greenland sharks reach sexual maturity only around age 150. (Source: Science (2016))

Fact or Myth: "Pistol shrimp snap their specialized claw shut so rapidly that the collapsing cavitation bubble briefly reaches temperatures comparable to the surface of the sun."

Wed, 21 Oct 2026 13:00:00 GMT

FACT — Shrimpoluminescence produces a 4,700 K plasma flash underwater. The high-velocity water jet forms a low-pressure vapor bubble whose implosion compresses trapped gas to ~5,000 Kelvin for nanoseconds, emitting a shockwave of 210 decibels and a brief flash of light. (Source: Nature (2001))

Fact or Myth: "Cuvier's beaked whales can dive nearly 3,000 meters deep and hold their breath for over three hours by collapsing their lungs and slowing their heart rate to a few beats per minute."

Wed, 21 Oct 2026 12:00:00 GMT

FACT — Extreme mammalian diving relies on myoglobin oxygen stores and profound bradycardia. To prevent nitrogen narcosis and decompression sickness, deep-diving whales collapse their pulmonary alveoli below 100 meters and rely on dense muscle myoglobin and vasoconstriction to ration oxygen only to the heart and brain. (Source: Journal of Experimental Biology (2020))

Fact or Myth: "Oriental hornets harvest solar energy using microscopic grooves in their yellow abdominal cuticle that trap and convert sunlight into electrical voltage."

Wed, 21 Oct 2026 11:00:00 GMT

FACT — Xanthopterin pigment in hornet shells functions as a biological solar cell. Biophysical analysis revealed that nanostructured layers in the hornet's brown and yellow exoskeleton guide photons to xanthopterin pigment granules, generating a measurable photovoltaic potential under midday sun. (Source: Naturwissenschaften (2010))
