A study by NYU School of Medicine found that aging skin experiences a decline in capillary-associated macrophages, which impairs microvascular repair. Boosting these macrophages with growth factors in mice improved blood flow and capillary repair, suggesting potential avenues for reversing skin aging, though human applications remain untested.
Frogs breathe and drink through their porous, moist skin, which contains blood vessels for gas exchange and water absorption, allowing them to survive underwater and during hibernation, though this makes them vulnerable to pollutants and climate change.
The article discusses proven methods to boost collagen production in the skin, as recommended by dermatologists, though specific techniques are not detailed in the provided excerpt.
The article reviews the best collagen peptide supplements, highlighting their benefits for skin, hair, nails, joints, and bones, and provides expert insights on choosing effective products to support healthy aging and tissue repair.
The skin, being the largest and most visible organ, can offer insight into our overall health. Various rashes and skin changes can indicate underlying illnesses such as Lyme disease, blood vessel issues, metabolic disorders, and heart conditions. Recognizing these skin signs and seeking medical attention when necessary can help in early diagnosis and treatment of potentially serious health issues.
Paleontologists have discovered a 290 million-year-old skin fossil in an Oklahoma cave, making it the earliest known example of a fossil from an amniote. The fossil is believed to have come from a reptile with a rough skin surface similar to that of a crocodilian animal. The discovery is significant for understanding the evolutionary history of animals, as skin fossils are rare due to their fragility. The cave's unique conditions, including soft sediment and a lack of oxygen, contributed to the preservation of the skin fossil. Although no nearby skeleton was found, the discovery provides valuable insights into prehistoric life.
Scientists have discovered the oldest-known piece of fossilized skin, a pebbly scrap from a 289 million-year-old reptile, offering rare insight into the evolution of skin. The specimen was found in the Richards Spur limestone cave system in Oklahoma, preserved by ideal conditions including rapid burial, low oxygen levels, and hydrocarbons from an oil seep. The texture of the skin resembles that of a crocodile, providing valuable clues to how skin evolved in ancient reptiles.
Researchers have discovered the world's oldest known fossilized skin, dating back around 289 million years, from a species of reptile that predates dinosaurs. The skin fragment, found in an Oklahoma limestone cave, is at least 130 million years older than the previous oldest known skin fossil. The sample, resembling crocodile skin with hinged regions similar to snakes and worm lizards, provides insight into the evolution of terrestrial animals and the importance of the epidermis as a barrier between internal body processes and the external environment. The study was published in the journal Current Biology.
Scientists have discovered the oldest known piece of preserved skin, dating back about 289 million years to the early days of the Permian period, in a cave in Oklahoma. The fossilized skin, resembling that of early reptiles, provides valuable insights into the adaptation of terrestrial animals to life on land and sheds light on the later development of feathers and hair. The rare find offers crucial information about the evolutionary history of life on Earth and the dynamics of ancient ecosystems during a pivotal time in Earth’s history.
New research suggests that a common microbe, Staphylococcus aureus, may directly cause itchiness on the skin it colonizes by releasing an enzyme that activates nerve cells and generates an itch sensation. The study found that an FDA-approved anti-clotting medication can block this itch response, potentially offering a new treatment for itchy skin conditions like eczema. The findings open up a new understanding of the role of bacteria in causing itching and may lead to more targeted treatments that do not harm beneficial bacteria on the body.
Consuming cucumbers provides several health benefits, including hydration, regulation of blood pressure, improved digestion, reduced blood sugar levels, and enhanced skin health. Cucumbers are rich in water, potassium, magnesium, and dietary fiber, making them a nutritious addition to a healthy diet.
The cycle of itching and scratching can be difficult to break due to the evolutionary reflex developed to expel unwanted visitors on the skin. Scratching provides temporary relief by inflicting a little pain, which inhibits the sensation of itching. However, scratching further damages the skin and activates nerve fibers, intensifying the itch-scratch cycle. The neurotransmitter serotonin plays a role in this cycle, inhibiting pain but also activating itch neurons. Scratching also activates the brain's reward system, providing pleasure. While there are treatments available, efforts are being made to develop therapeutics that target neural pathways involved in itching. In the meantime, refraining from scratching can be challenging, but alternative methods like cold compresses or intense heat can help interrupt the sensation.
The gut microbiome is not the only microbiome in the body. The skin has its own active microbiome that plays a crucial role in immunity, skin disorders, wound healing, and even certain types of cancer. The skin microbiome consists of different communities of microbes shaped by the skin's physiology. Skin microbes coevolved with the body to protect it and limit inflammation. Dysbiosis, an imbalance of good and bad skin microbes, can lead to various skin conditions such as acne. Factors like aging, sex, environment, and antibiotics can impact the diversity and health of the skin microbiome.
Researchers at Harvard Medical School have discovered that the skin, rather than pre-existing genetic programming, instructs nerve cells on how to mature for specific sensory tasks. The study found that skin cues determine whether nerve endings develop to detect sensations in hairy or hairless skin. This finding could potentially lead to therapies for damaged nerves and a better understanding of congenital neuropathies. The research highlights the significant role of the skin in neural development.
