Barn owls with smaller black spots have higher testosterone levels, which might be due to genetic effects on hormone regulation rather than hormone effects on coloration.

More exercise might link to hair loss, but other factors also matter.

Scientists now better understand the genetics of hypohidrotic ectodermal dysplasia, leading to more accurate diagnoses and potential new treatments.

Baldness is more common in Chinese men than women, increasing with age, and is influenced by genetics.

Researchers developed reliable models to predict how well certain compounds bind to androgen receptors, emphasizing the importance of atomic electronegativity.

The research suggests that the global distribution of PCOS is likely due to historical human migration and that genes affecting PCOS may have different impacts on males and females.

Skin grafts are effective for chronic leg ulcers, especially autologous split-thickness grafts for venous ulcers, but more data is needed for diabetic ulcers.

Using 17-hydroxyprogesterone levels to diagnose nonclassic congenital adrenal hyperplasia can result in many incorrect diagnoses.

Using CRISPR for gene editing in the body is promising but needs better delivery methods to be more efficient and specific.

The conclusion is that genetic testing is important for diagnosing and treating various genetic hair disorders.

The research found that genetic factors for male pattern baldness in African men differ significantly from those in Europeans.

Treatment with biologic agents can significantly improve psoriasis symptoms, and blood biomarkers could potentially predict individual patient's response to treatment.

Recent selection on immune response genes was identified across seven ethnicities.

The study found that in Latin America, ancestry varies by location, influences physical traits, and affects how people perceive their own heritage.

Men generally have more severe COVID-19 cases and higher death rates than women due to biological differences.

Women with greater androgen sensitivity respond better to finasteride for hair loss.

Most people in Turkey start getting gray hair around 33 years old, with factors like age, education, hair loss, skin type, family history, and anxiety playing a role.

The study found that diseases can be grouped by symptoms and that the accuracy of predicting disease-related genes varies with the data source.

Five new mutations in the androgen receptor gene were found, helping to understand androgen insensitivity syndrome better.

Researchers found 71 genetic regions linked to male pattern baldness, which account for 38% of its genetic risk.

Rare genetic variants in five specific genes are linked to male-pattern hair loss but only account for a small part of the risk.

iPSCs show promise for hair regeneration but need more research to improve reliability and effectiveness.

Forensic DNA phenotyping is becoming useful for predicting physical traits in criminal investigations but is limited by ethical concerns and incomplete genetic understanding.

Custom skincare can be made based on genes, fewer cats in Lublin have FeLV/FIV than national average, and studies also looked at small water bodies, river pollution, guppy growth, toxins in biochars, palm oil issues, and pumpkin seed oil for hair strength.

Human hair can be classified into eight types based on physical features, not ethnicity.
