High air pollution does more than just irritate your lungs, research confirms it also affects the way you look. By using ESA-provided pollution maps along with ultraviolet radiation data, cosmetics firm L’Oreal plans to investigate the future possibility of producing skincare products customised for local conditions.
Today the skin-ageing effects of ultraviolet (UV) rays are well known, but the harmful consequences of air pollution on our skin are less easily quantified outside of laboratories. Employing a 2800-strong team of scientists and support staff, L’Oreal has carried out field studies on this subject.
Working with the French Regional Centre for the Fight against Cancer and the Mexican National Institute of Public Health, in 1999 the company began a nine-month study in and around Mexico City - one of the most polluted cities in the world. To study the effects of ozone and nitric oxide on the skin, 96 people in a highly polluted district of the city were compared to 93 subjects living in a less exposed urban area 75 km away.
“We saw many differences between the two groups,” explained François Christiaens of L’Oreal. “We observed increased oxidation of the sebum - the oily secretion that lubricates and protects skin and hair - and the very dry or very greasy skin features of our volunteers living in Mexico City.”

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
