Small fish may have small brains, but they’re not stupid. A common coral reef fish called damselfish can learn to avoid predators from more experienced kin, even in complete darkness, new research shows. Biologists have long known that fish use a variety of signals to warn others when predators approach, including visual cues, chemical cues, warning sounds and cues felt by motion. Until now, visual cues were thought to be an essential part of the mix. But new work from a team of biologists from Australia and Canada has shown otherwise, as reported today in the journal Proceedings of the Royal Society B. Many fish can often detect an approaching predator by its distinct odor. Some are born hardwired to associate the smell of predators with danger, whereas others are born oblivious and must learn to make the connection. To test which combination of stimuli damselfish use for such “social learning” — or learning by the example of individuals — the team conducted a series of experiments involving pairs of experienced and naive fish juveniles that weren’t old enough to have learned predator-prey prowess. They placed the pairs in tanks containing the odors of a predatory guppy fish, and carried out tests in either dark or light conditions. When the experiments had concluded, they placed the naive fish in new, solitary tanks and introduced the guppy odor again.

Adapted by Sterling Volunteers staff. Children usually are friendly and trusting of most people and therefore have a difficult time identifying predators. Predators can be anyone, including a family member, colleague, coach or friend.

At one point we fist-bumped. We are a Tinder success story, of sorts. We met after swiping right on each other in June last year. It was at once apparent that romance was not on the cards, but we became friends. This September, just after our first anniversary of meeting, we moved in together. I get annoyed when he eats my yoghurt; he eats too much yoghurt. It could not be more domestic. In the intermittent two years, my older sister got engaged to her Tinder date, and my little sister celebrated her th match.
The only people for whom Tinder has any dangerous fascination are either older, in relationships, or both. Consciously or otherwise, this must have been the imagined audience for Hack Live, which portrayed Tinder mostly negatively — responsible for either the death of modern romance, or deaths full stop.

These young people fall through the cracks in the law, without the same basic protections as younger children to be kept safe, recover or get justice. Sixteen is the legal age of consent to sexual activity. Although many laws declare that any person under the age of 18 is a child, the law protecting children from sexual crimes does not provide young people age 16 and 17 the same level of protection as younger children. Our report examines why older teenagers are particularly at risk of child sexual exploitation, what can happen when a young person reveals they are being exploited and why existing protection is insufficient.
It uncovers a series of new findings based on interviews and case notes with specialist practitioners, and analysis of Crime Surveys and Freedom of Information responses. Child sexual exploitation is someone taking advantage of you sexually, for their own benefit. None of these reasons are acceptable enough to be subjected to such wreckage. The only way to survive a situation like this is to save yourself or remain unsaved.
Teenage girls aged 16 and 17 are more likely to be a victim of a sexual offence than any other age group, with almost one in ten saying they experienced a sexual offence in the last year. We know from our own specialist services that people who sexually exploit children particularly prey on the most vulnerable 16 and 17 year olds. They will go to great lengths to target vulnerable young people, using gifts, affection, money, alcohol, drugs – or the promise of love.
Victims are commonly teenagers in the care system, with backgrounds of abuse and neglect, learning disabilities or with mental health problems.
Various laws are in place to help control such behaviour, protect the vulnerable and restrain related criminal offences. However, enforcement of such laws has become a significant challenge with the advent of social media creating a new platform for this old crime. This move necessitates consideration of approaches that are suited to this new platform and the way in which it affects the Cycle of Entrapment. This paper reviews definitions of, and features of, paedophilia and other related —philias, and sexual offences against children, and seeks through the understanding of these to determine where specific detection approaches are effective.

Performed the experiments: NN LP. Analyzed the data: MG. Performed the veterinarian inspections: NN LP. It is assumed that predators mainly prey on substandard individuals, but even though some studies partially support this idea, evidence with large sample sizes, exhaustive analysis of prey and robust analysis is lacking. We gathered data from a culling program of yellow-legged gulls killed by two methods: by the use of raptors or by shooting at random.
We compared both data sets to assess whether birds of prey killed randomly or by relying on specific individual features of the prey. We carried out a meticulous post-mortem examination of individuals, and analysing multiple prey characteristics simultaneously we show that raptors did not hunt randomly, but rather preferentially predate on juveniles, sick gulls, and individuals with poor muscle condition.
Strikingly, gulls with an unusually good muscle condition were also predated more than expected, supporting the mass-dependent predation risk theory.
