A small pilot clinical study suggests that the drug nitisinone increases melanin production in some people with oculocutaneous albinism type 1B (OCA-1B), a rare genetic disease that causes pale skin and hair and poor vision. Increased melanin could help protect people with the condition against the sun's UV rays and promote the development of normal vision.
Braden Milford, a high school senior from Tulsa, Oklahoma, was recently selected as a Three Dot Dash Global Teen Leader. Milford, who created a water purification system for a school project, is now receiving global recognition and interest after creating and using a simulated stream to show how it would work. Milford explains, “My project associates environmentally extracted bacteria with algae in a jelly-like system that you can then deploy into a stream and it will intake water toxins.”
Milford will travel to New York in March, where he’ll pair up with a distinguished mentor in the science field to help his project grow. He is also in the running for one of the top science competitions in the nation, called Regeneron Science Talent Search. If he makes the top 40, he’ll take in 25 thousand dollars. If he is the overall winner, he’ll receive 250 thousand dollars towards his project. No matter what, Milford plans to continue working on ways to develop his water purification system. He says, “Seeing what will make an impact on the world really drives me forward.”
A new study has found no evidence that teenage cannabis use is lower in countries with tougher policies.
New research has begun to identify the circumstances by examining relationships between early age of first intoxication (less than 15 years), drinking in different contexts such as one's own home, at friends' homes, or outdoor settings, and problems that arise in those contexts.
A genetic variant found only in people of African descent significantly increases a smoker's preference for cigarettes containing menthol, a flavor additive. The variant of the MRGPRX4 gene is five to eight times more frequent among smokers who use menthol cigarettes than other smokers. The multi-ethnic study is the first to look across all genes to identify genetic vulnerability to menthol cigarettes.

According to a large-scale study of American high school students, legalizing medicinal marijuana has actually led to a drop in cannabis use among teenagers. The study used the results of an anonymous survey given to more than 800,000 high school students across 45 states to calculate the number of teens who smoke cannabis.
Cannabis is the most commonly used recreational drug by teenagers worldwide. In Canada, among youth aged 15 to 19 years, the rate of past-year cannabis use is 20.6 percent, while in England, 4 percent of adolescents aged 11 to 15 years used cannabis in the last month.
In January 2019, 24-year-old William Brown died after his vape pen exploded, injuring his face and neck. His is the second recent death from an exploding e-cigarette among thousands of injuries and burns. According to a study published by Tobacco Control, there were more than 2,000 vape pen explosion and burn injuries in the United States from 2015 to 2017.
The U.S. Fire Administration blames the injuries and fires on the prevalence of lithium-ion batteries that are found in e-cigarettes. According to their report, “It is this intimate contact between the body and the battery that is most responsible for the severity of the injuries that have been seen.”
