Nothing will make you feel like Tony Stark more than being able to change the shape of displays with your hands, pulling objects and data out of the screen and playing with them in mid-air.

Right now, that's just in an Avengers movie. Instead, we live in a world of flat-screen displays, even though the real world is not flat, it has hills and valleys, people and objects. Being able to manipulate a display and drag features into a 3-D world is the purpose of GHOST (Generic, Highly-Organic Shape-Changing Interfaces), an EU research project designed to tap humans’ ability to reason about and manipulate physical objects through the interfaces of computers and mobile devices.

As millions of visually impaired people will tell you, people with full sight often make incorrect assumptions about their capabilities. It's not mean, it's benevolent, but people are uncomfortable with not knowing what is proper decorum and some can make hilarious errors.

The Phase IIb pivotal study of P2B001 for the treatment of early stage Parkinson's Disease has been announced as a success. 

P2B001 is a combination of low dose pramipexole and low dose rasagiline administered as a proprietary sustained release formulation. The study, titled A Phase IIb, Twelve Week, Multi-Center, Randomized, Double-Blind, Placebo-Controlled, Parallel Group Study, To Determine the Safety, Tolerability and Efficacy of Two Doses of Once Daily P2B001 in Subjects with Early Parkinson's Disease, showed that it met primary and secondary clinical endpoints for both dose combinations. Specifically, the results showed:

A milk-and ochre-based paint dates that may have been used by inhabitants to South Africa to adorn themselves or decorate stone or wood slabs has been dated to 49,000 years ago. 

While the use of ochre by early humans dates to at least 250,000 years ago in Europe and Africa, this is the first time a paint containing ochre and milk has ever been found in association with early humans in South Africa, said Paola Villa, a curator at the University of Colorado Museum of Natural History and lead study author.

The milk likely was obtained by killing lactating members of the bovid family such as buffalo, eland, kudu and impala, she said.

The brains of people with recurrent depression have a significantly smaller hippocampus (the part of the brain most associated with forming new memories) than healthy individuals, according to a study of nearly 9,000 people called the ENIGMA study.

The researchers say this is the largest international study to compare brain volumes in people with and without major depression. It highlights the need to identify and treat depression effectively when it first occurs, particularly among teenagers and young adults. Using magnetic resonance imaged (MRI) brain scans, and clinical data from 1,728 people with major depression and 7,199 healthy individuals, the study combined 15 datasets from Europe, the USA and Australia. 

There is a paradox when it comes to guns in America. In states like California, gun ownership has doubled in the last 15 years while murder rates dropped substantially in that time. Today,
almost one in three US adults owns at least one gun, and owners are more likely to be white married men over the age of 55, hardly a high crime demographic.

Instead of being for crime, most guns are used for suicide - and even then fewer people commit suicide with guns in the US than do by hanging in Japan. Though Switzerland had always scoffed at the notion that guns cause crime - gun ownership is even higher there - similar results in more than one country dispel the myth that more legal guns lead to more crime or more murders.

A federal preschool program did more than improve educational opportunities for poor children in Mississippi during the 1960s - it created activists. 

Pink salmon that begin life in freshwater with high concentrations of carbon dioxide, which causes acidification, are smaller and may be less likely to survive, according to a new study.

The risks of ocean acidification on marine species have been studied extensively but the impact of freshwater acidification is not well understood. The study is one of the first to examine how rising carbon dioxide levels caused by climate change can impact freshwater fish.
