Scientists have discovered that sunburn damages a protective protein called YTHDF2 in skin cells, leading to uncontrolled inflammation that can trigger skin cancer. The research highlights how UV exposure breaks down YTHDF2, allowing non-coding RNAs to activate immune pathways associated with cancer development, offering new avenues for prevention and treatment.
A study by Binghamton University researchers explains that skin wrinkles with age due to repeated stretching and buckling, similar to denim creases, with changes in skin stiffness and collagen density contributing to this process. The findings provide experimental evidence of the physical mechanisms behind aging skin and have implications for skincare and understanding other tissues, as well as the impact of sun exposure on skin aging.
A Cambridge surgeon warns parents about the risks of sun exposure to children, emphasizing that repeated UV damage can lead to skin cancer later in life, and advises protective measures beyond just sunscreen.
A recent study reveals that UV and near-UV lamps used in gel manicures can chemically damage skin molecules, including enzymes like tyrosinase, leading to increased oxidative stress, potential skin aging, and higher skin cancer risk. The lamps emit UVA radiation comparable to sunlight, and repeated exposure may cause cumulative skin damage, emphasizing the need for protective measures and regulatory standards.
The New York State health department warns residents, especially families with children, about the dangers of UV radiation and skin cancer, emphasizing the importance of using broad-spectrum sunscreen with at least SPF 15 or 30, reapplying every two hours, and checking expiration dates to stay protected during the sunny summer months.
Despite airplane windows blocking most UVB rays, UVA rays can still penetrate and cause skin damage, so wearing sunscreen on flights is recommended for everyone, especially for those with higher risk factors like fair skin or a history of skin cancer.
Researchers at Tel Aviv University have discovered a new method to treat cancer by targeting a protein called Ly6a, which acts as an immune "brake". This protein, found in high levels in tumors, helps cancer evade the immune system. By using anti-Ly6a antibodies to release these brakes, the immune system can effectively attack and reduce tumors, including those resistant to current immunotherapies. The findings, published in Nature Communications, could lead to new treatments for cancer patients who do not respond to existing therapies.
Melanoma skin cancer cases in the UK are at an all-time high, with Cancer Research UK predicting 20,800 diagnoses this year. The rise is attributed to an ageing population and increased awareness of skin cancer signs. Nearly 90% of cases are linked to excessive UV radiation, and the charity emphasizes the importance of sun protection and early detection. The highest increases are seen in older adults, but younger people are more aware of UV risks. Early detection significantly improves survival rates, with almost 90% of diagnosed individuals surviving for 10 years or more.
A study published in the Journal of Investigative Dermatology reveals that ultraviolet (UV) radiation can influence subcutaneous fat regulation by increasing norepinephrine levels, which decreases leptin and promotes the browning of fat, thus enhancing energy expenditure. This discovery could lead to new treatments for obesity and metabolic disorders, although further research is needed to address the long-term effects and safety of UV exposure.
Fitness celebrity Richard Simmons revealed he was treated for basal cell carcinoma, the most common form of skin cancer, which can be easily missed or mistaken for another skin issue. Basal cell carcinoma is often discovered during routine skin checks and is estimated to affect several million people in the United States each year. It is caused by cumulative, chronic exposure to UV radiation and is most common in adults over age 40. Prevention and early detection are crucial, and the disease is very treatable when diagnosed.
Sunlight can cause irreversible damage to the eyes within minutes, even though the effects may not be immediately apparent. The sun's ultraviolet (UV) radiation can lead to conditions such as surfer's eye, cataracts, and even rare types of cancer. It is crucial to protect the eyes by wearing sunglasses that provide 99 to 100 percent UV protection and brimmed hats. Looking directly at the sun, especially during a solar eclipse, can cause permanent eye damage in less than a minute. To safely view an eclipse, it is recommended to use approved eclipse glasses from reliable sources to avoid counterfeit and unsafe versions.
Skin cancer rates have been increasing consistently for the past 30 years, with melanoma cases rising by 48% between 1992 and 2017. While public awareness of the risks of excessive sun exposure and tanning beds has increased, skin cancer rates continue to rise. Dermatologists emphasize the importance of not relying solely on sunscreen for protection, but also practicing abstinence from sun exposure during peak hours, wearing protective clothing, seeking shade, and using sunglasses with a UV 400 rating. Additionally, it is crucial to apply sunscreen correctly, using at least SPF 45 and following the rule of teaspoons for adequate coverage. New sunblock products, such as La Roche-Posay Anthelios Age Correct SPF 50, Supergoop! (Re)setting 100% Mineral Powder SPF 35, and Coola Classic Body Organic Sunscreen Spray SPF 50, offer innovative solutions for sun protection.
Eye surgeon Dr. Ronnie Bhola warns that prolonged exposure to UV rays from the sun can lead to severe eye damage and vision loss, including conditions like corneal damage, cataracts, and macular degeneration. He emphasizes the importance of protecting our eyes by wearing UV-blocking sunglasses and hats, especially in locations with intense UV rays such as beaches, higher altitudes, and countries closer to the equator. Children and older individuals are more vulnerable to UV radiation, and individuals with lighter eye colors, particularly blue eyes, are at higher risk. Bhola urges the public to take preventive measures, such as wearing proper sunglasses and hats, to reduce the potential harm caused by UV rays and preserve eye health.
Dermatologist Dr. Fayne Frey emphasizes the importance of protecting the skin from the sun's harmful UV radiation, which can cause both short-term effects like sunburn and long-term consequences such as an increased risk of skin cancer. To safeguard against the sun, it is recommended to avoid intense midday sun, cover the skin with clothes and wear a hat with a brim. Sunscreen should be applied to exposed skin, with a minimum SPF of 30 for all skin types. Sunscreens can be divided into chemical and mineral types, with mineral sunscreens being favored by the French Society of Dermatology due to their reduced likelihood of side effects.
TikTok user FindingFiona's claim that sitting in a window seat on a plane exposes you to stronger UV radiation is partially correct. While airplane windows block out most UVB rays that cause sunburn, they don't fully keep out UVA rays, which can contribute to premature aging, wrinkles, and skin cancer. This is also true for non-airplane windows. Wearing sunscreen on a plane is important for everyone, especially those with a personal or family history of skin cancer, fair skin, medical conditions that increase sun sensitivity, or those on medication that increases sun sensitivity. It is recommended to use broad-spectrum sunscreen that protects against both UVA and UVB rays and to also use physical protection like hats, sun protective clothing, and sunglasses.
