A cure for baldness? A team of scientists in the U.S. and Britain may have taken a huge leap forward in finding a cure for baldness. And it would be more effective and useful to more people than current remedies like drugs or hair transplants.
Researchers at Columbia University Medical Center has teamed up with University of Durham to generated new hair follicles that grow human hair for the first time ever.
Their plan was to start with material taken from the base of a hair and use it to grow many new hairs. The technique involved harvesting cells from the base of a human hair follicle, called the dermal papillae. These cells were cloned in the laboratory and then implanted into human skin grafted to the back of a mouse.
According to lead researcher Angela Christiano, associate professor of molecular dermatology at Columbia, this discovery has the potential to “revolutionize” the medical treatment of hair loss.
Watch the video below of Professor Angela Christiano of Columbia University and Colin Jahoda of Durham University, UK, explain how they created new hair in human skin by culturing cells taken from the inside of hair follicles.

The first advertising billboard in the world that produces water from the air in Lima, Peru. The breakthrough is designed to inspire more young people to pursue careers in engineering at the University of Engineering and Technology of Peru. It also helps the capital of Lima, located in the desert and humid despite lack of rain, to generate drinking water to some of its 7 million people.
The university came up with the idea to transform the country’s high levels of into water in conjunction with ad agency Mayo DraftFCB. The billboard system uses reverse osmosis, a water purifying process, and then stores the water in tanks that hold 20 liters each. The water is dispensed at the bottom of the structure. The billboard has already produced 9,450 liters of water in just three months, according to Mayo, which it says equals the water consumption of ‘hundreds of families per month. Watch the video below to learn more about the project.
