To make things clear - Maldacena's universe is not like the one we actually live in! It's a model, a toy universe, which comes complete with its own physics. It's a hologram because all the physical goings-on inside it can be described by a physical theory that's only defined on the boundary. What's more, it's a universe in which the gravity/quantum conundrum has been resolved completely: the boundary theory is purely quantum, it contains no gravity, but a being living in the interior will still experience gravity. Gravity in this universe is part of the holographic illusion. More on COSMOLOGY: http://www.scoop.it/t/science-news?tag=cosmology

- Harvard Buiness School via 3BL Media What is corporate social responsibility (CSR), and why has it become more important? Since the turn of the century, and especially after the financial crisis, we have begun to look harder at the role corporations play in our society. A corporation exists not only to generate profits for shareholders, but also to add value to society. So, we might ask, what in particular is Company X doing for society? If we don’t answer that question now, we’ll never answer it—and Company X and its counterparts will keep chugging along, seeking profit above all, and we’ll have the equivalent of a subprime mortgage crisis all over again...

Biomorphic House with organic skin designed by Pavie Architects & Design has aerodynamic shapes, and is situated 1000 meters over the Mediterranean Sea. It's formed to withstand winter storms perfectly and provides enough windows with transparent photovoltaic-cells to secure power sufficient for the heating, and electricity needs. The interior design is the natural extension of the inside of the skin. Free shaped floors, walls and ceilings give the feeling of a super luxurious space ship. This pilot project, through a self-powered water electrolyze process, converts the obtained energy to hydrogen and saves it for a future use. Later, a hydrogen powered PEM-Fuel-Cell generator can supply electricity to the house, releasing pure water and reusable heat as side-products...
