Master's Open Day at UNU-MERIT
UNU-MERIT will host a Master’s Open Day on Saturday 7 October 2017. Our top-ranked MSc in Public Policy and Human Development (MPP) emphasises the connection between public policy and decision-making processes, as well as the principles of good governance.

Students who successfully complete our Master’s programme receive a double degree issued by the United Nations University and Maastricht University. Several information sessions will be offered throughout the day and visitors will have the opportunity to talk with staff and students.

  • New sunscreen features melanin-mimicking nanoparticles
    Researchers at the University of California, San Diego have created a sunscreen that both mimics and enhances the skin's natural protective abilities.

    The team were able to tap into the skin's defence mechanisms using nanoparticles of oxidised dopamine. Tests showed the particles mimic melanosomes, the organelle in skin cells that synthesizes, stores and transports melanin. Researchers first developed the nanoparticles two years ago while studying the behaviour of melanins in bird feathers.

    Researchers believe their breakthrough could yield treatments for vitiligo and albinism, diseases caused by defects in the body's melanin production system. Patients diagnosed with vitiligo and albinism are at a much higher risk of skin cancer.

    Melanosomes are produced by cells called melanocytes, found among the bottom layers of the epidermis. The organelles deliver melanin to keratinocytes, skin cells in the upper layer of the epidermis. There, melanin goes to work protecting skin cells from ultraviolet radiation.

    In lab tests using tissue culture, researchers showed the nanoparticles are absorbed and distributed throughout keratinocytes just like natural melanin. The nanoparticles also protected skin cells from DNA damage caused by ultraviolet radiation.
