A 14-year-old teenager was named"America's Top Young Scientist"after winning thisyear's 3M Young Scientist Challenge,a national science competition.He was given the titlefor creating a bar of soap(肥皂)that fights low-grade skin cancer and also awarded
$25,000 for his research.
Heman Bekele,who is a freshman at WT Woodson High School,moved to Virginia fromEthiopia,where he observed people constantly exposed to the sun and suffering from skincancer.While he didn't initially give it much thought,as the competition drew near,heremembered his experiences in Ethiopia and decided to focus his research on skin cancer.
Heman started doing experiments at home and doing testing on digital models.He
leamed much ahout dendritic cells(named for their tree-like branches),which boost human
immune(免疫的)responses.In his submission video to 3M,Heman explains,“When skincancer cells develop,they weaken dendritic cells in the body,allowing the cancer to takeover.”He said the soap contains agents that could potentially reactivate dendritic cells thathelp eliminate the cancer cells.
The soap can be applied to the skin every couple of days and then the person with skincancer will start to see progress.“The average price of skin cancer treatment in the US aloneis almost 340,000,but my bar of soap only costs $8.50 to ereate,and it can have the sameeffects as something that people would pay thousands and thousands of dollars to try to get,"Heman said.
For now,Heman said he has a five-year plan.At the end of it,he hopes to havecreated a nonprofit organization where he can provide accessible skin cancer treatment to asmany people as possible.But to achieve his goal,he would have to get his treatment throughclinical trials and have it certified by the Food and Drug Administration(FDA),he said.
