(Financial Times) -- The increasing amount of personal information that can been gleaned by computer programs that track how people use Facebook has been revealed by an extensive academic study. Such programmes can discern undisclosed private information such as Facebook users' sexuality, drug-use habits and even whether their parents separated when they were young, according to the study by Cambridge university academics. In one of the biggest studies of its kind, scientists from the university's psychometrics team and a Microsoft-funded research centre analysed data from 58,000 Facebook users to predict traits and other information that were not provided in their profiles. The algorithms were 88 per cent accurate in predicting male sexual orientation, 95 per cent for race and 80 per cent for religion and political leanings. Personality types and emotional stability were also predicted with accuracy ranging from 62-75 per cent. Facebook declined to comment. The study highlights growing concerns about social networks and how data trails can be mined for sensitive information, even when people attempt to keep information about themselves private. Less than 5 per cent of users predicted to be gay, for example, were connected with explicitly gay groups. Michal Kosinksi, one of the report's authors, told the Financial Times that the university's techniques could easily be replicated by companies to infer personal attributes a person did not wish to share, such as sexual orientation or political views: "We used very simple and generic methods. Marketing companies and internet companies could spend much more time and resources, and hence get much higher accuracy than we did." Last week , the EU agreed to water down proposals for a radical overhaul of data privacy regulation. The move reflects governments' reluctance to impede internet businesses that might spur economic growth, and follows fierce lobbying from technology companies including Facebook and Google. Personal data has become big business. Wonga, the UK online lender, makes credit judgments within seconds based on thousands of pieces of information, including an applicant's Facebook profile. Tesco, the supermarket chain, this month started to use its customers' shopping histories to sell targeted online advertising. The report also revealed some unexpected correlations -- such as people who liked 'curly fries' having higher IQs, while those who like Facebook's "Sliding on Floors With Your Socks On" page were unlikely to use drugs.

According to the study by Cambridge Academics how accurately were they able to predict sexuality?

Mechanical energy is a combination of the energy of motion or position. This type of energy describes objects that are moving or could move. A moving ball can have energy from motion. An arrow can also have the energy of motion. Both are types of mechanical energy. Can you think of some other examples? Where does the energy of motion come from? It comes from the energy created by position. This energy is stored energy. This means it is not moving yet, but it has the potential to move. How can you store energy? The arrow gains energy from the drawn bow. As the arrow is released, the bow releases its stored energy and puts the arrow into motion. Can you think of some other ways to store energy using position?

Is an arrow released from a bow an example of mechanical energy?

The film begins with Brick Bardo ( Tim Thomerson , from ( ( Dollman hitchhiking to get to the town of Pahoota , where he tries to find a girl named Nurse Ginger ( Melissa Behr , who was shrunken to 11 inches in ( ( Bad Channels , to prove to her that she's not alone .
