Long-lived magnetic fields are sustaining a mammoth network of spaghetti-like gas filaments around a black hole, a new study suggests. Previously, it was not clear what prevented the delicate filaments from being destroyed by competing gravitational forces.

The black hole lies at the heart of a large galaxy known as NGC 1275, which itself lies near the centre of a cluster of galaxies called Perseus.

As the black hole sucks in gas from its surroundings, it powers jets of matter that produce bubbles of energetic particles in the surrounding cluster gas. As these bubbles grow and rise, cooled gas from NGC 1275's core gets drawn into long tendrils in their wake, like the strings that trail behind balloons.

Andrea Camperio Ciani and colleagues at the University of Padua, Italy, showed that the female relatives of homosexual men tend to have more children, suggesting that genes on the X chromosome are responsible. Now the team have shown that the same is true for bisexuality.

"The answer is remarkably simple: the same gene that causes men to like men also causes women to like men, and as a result to have more children."

In 2003, psychologists at the University of Glasgow, UK, published a study in which they asked heterosexual students in campus bars and cafés whether they had been drinking, and then got them to rate photos of people for attractiveness. While the results supported the beer goggles theory, another explanation is that regular drinkers tend to have personality traits that mean they find people more attractive, whether or not they are under the influence of alcohol at the time.

To resolve the issue, a team of researchers led by Marcus Munafò at the University of Bristol in the UK conducted a controlled experiment. They randomly assigned 84 heterosexal students to consume either a non-alcoholic lime-flavoured drink or an alcoholic beverage with a similar flavour. The exact amount of alcohol varied according to the individual but was designed to have an effect equivalent to someone weighing 70 kilograms drinking 250 millitres of wine — enough to make some students tipsy. After 15 minutes, the students were shown pictures of people their own age, from both sexes.

Both men and women who had consumed alcohol rated the faces as being more attractive than did the controls (Alcohol and Alcoholism, DOI: 10.1093/alcalc/agn065).

The French journalists captured what they claimed were usernames and passwords of reporters from at least two media outlets — eWeek and CNET News. The eWeek reporter told organizers his login credentials looked like they were legitimate, while the CNET information appeared to be bogus.
