NASA's Voyager 1, launched in 1977, was propelled into deep space with the help of Jupiter's and Saturn's gravity. Now it is about to leave the solar system. But exactly when is unclear.
Voyager 1 is traveling at a speed of about 3.6 Astronomical Units (AU) per year - one 'AU' equals the distance between the Sun and the Earth, or 93 million miles.
A new review of studies suggests that fructose may not be as bad for us as previously thought - it may even provide some benefit.
Fructose, which is naturally found in fruit, vegetables and honey, is a simple sugar that together with glucose forms sucrose, the basis of table sugar. It is also found in high-fructose corn syrup, the most common sweetener in commercially prepared foods.
A report from market research agency Conquest into the social media habits of 14-24 year olds claims that Facebook's core audience - teenagers - are starting to fall out of love with the website and that activity may have peaked amid a groundswell of dissatisfaction and concerns over privacy and even bullying.
20 years ago in America, members of Congress, armed with studies showing that a college degree meant more lifetime earnings on average than a high school diploma, decided the way to boost income for everyone was to make sure everyone got a college degree.
What changed? Very little. The best and richest students still go to the top universities while everyone else does not; but student loan debt has climbed as universities, able to charge unlimited amounts, did just that and hired more people and built more buildings.
Tapping ocean energy sources like tides and offshore wind sound fine to people who understand nothing about science (the Anything But Oil contingent) but in reality it requires pile driving, the practice of pounding long, hollow steel pipes called piles into the ocean floor to support energy turbines and other structures.
Pile driving creates loud, underwater booms that can harm fish and other marine animals so if you're thinking CO2 is better for the world, you are right.
A trial of HPV vaccines in India, which has now been halted and is the subject of an investigation by the Indian government, was examining the safety and feasibility of offering a vaccine against the virus associated with cervical cancer.
The trial was run by the international health charity PATH and involved more than 23,000 girls from Gujarat and Andhra Pradesh states. A committee of scientists commissioned by the Indian Government to look into the trial said that the study involved a number of serious ethical violations. A new study by researchers at Queen Mary, University of London and the University of Edinburgh suggests that lack of data on cervical cancer in India did not support a trial of the vaccine to prevent the disease.
