Peer-Reviewed Publication

In article, a study performed by a group of Brazilian researchers elucidates action mechanism of visible light on skin and questions typical use of sunscreen. Most common sunscreens affect D vitamin absorption and fail to block visible light -- which, while not as damaging as UV rays, accounts for 45 percent of the solar radiation. The group patented skin-colored sunscreen which can block visible light.

Neuroimaging of soccer fans' brain reveals neural basis of ingroup altruistic motivation

D'Or Institute for Research and Education
Peer-Reviewed Publication

Study published in Nature's Scientific Reports journal reveals for the first time the brain functioning involved in altruistic motivation among soccer fans - a 'natural group' that shows strong bonds in real-life settings. The functional MRI study sheds light into the neural basis of prosocial behaviour of ingroup attachment.

New physical model explains the origin of Earth's water

Fundação de Amparo à Pesquisa do Estado de São Paulo
Peer-Reviewed Publication

Objects scattered to the inner region of the Solar System by Jupiter's growth brought most of the water now found on Earth. Authors of an journal Icarus article describe a computational model which simulates the gravitational interaction between celestial bodies during the era of planet formation, also providing basis for the hypothesis of the dragging of water-rich "planetesimals".
