Lesbian, gay, bisexual, transgender and intersex (LGBTI) people face specific challenges in their global fight for equality that goes beyond marriage, advocates say.
Nearly a dozen countries have legalised same-sex marriage, including Ireland, which approved marriage equality through a popular vote.
In the United States, bans on same-sex marriage in 14 states are no longer enforceable in the wake of a historic Supreme Court ruling.
But while marriage recognition is an important issue for many, advocates say there are other basic rights that are being denied to LGBTI citizens in 2015.

Hologram technology already exists. Whatever is not yet sufficiently advanced, however, we have witnessed some progress in this area as: hologram created in mid air by laser, 3D hologram displays, holograms in the toy industry and the like. Unfortunately Hologram display can not be touched and interaction with it would feel more natural.
That at least was true till now when a Japanese team of scientists from Digital Nature Group managed to create a hologram display that you can touch. The concept is similar to the hologram which was created in mid air (also in Japan). Namely, the laser is used to create display emits superfast and supershort radiation (measured in femtoseconds). These radiations wiggle molecules of air, while helping to ionize (resulting in their lighting). As we know, a set of ionized particles to a place called plasma, which is generated by the laser.
The very fact that the molecules are forced to move in the air is causing the ability to touch them. Namely, when you put a finger in the hologram air, molecules are hitting your skin and you feel like it you touched something. According to lead author of the study it feels like you’re touching sand paper or electrostatic shock. Additionally, by using a camera which is placed under the display you can recognize when you touched the display and where, and to convey the command somewhere in the software.
Scientists say that they have chosen femtosecond display nanoseconds because it is safer for the skin because there is not enough time to warm up and damage. This will allow interactive 3D holograms that can be touched, which will contribute to significant progress in hologram technology. The projection of such holograms may allow upgrading of our reality in the case if these kind of devices are placed all around us and project images and objects that we could touch.
This femtosecond laser-based volumetric display will be demonstrated to the public as a part of the Siggraph 2015 exhibition in August.

“I Am Not Nonviolent”: New #NinaSimone Film Captures Singer and Activist’s Uncompromising Voice – #jazz 3:11
Ajoutée le 24 juin 2015
http://democracynow.org – As the Black Lives Matter movement grows across the country and the the nation mourns the death of the nine worshipers killed at Charleston’s Emanuel AME Church, we look back at the life of one of the most important voices of the civil rights movement: the singer Nina Simone, known as the High Priestess of Soul. While Simone died in 2003, a new documentary, “What Happened, Miss Simone?,” sheds light on her music and politics. Her song “Mississippi Goddam” became an anthem of the civil rights movement. She wrote it in the wake of the assassination of Medgar Evers in Mississippi and the 16th Street Baptist Church bombing in Birmingham, Alabama, which killed four black children. We speak to the film’s director, Liz Garbus, and Al Schackman, Nina Simone’s guitarist and music director for over 40 years.
