Global warming is also held responsible for the cause of change in climatic conditions. Global warming not only affects trees, forests and human life, but also poses great threat to marine and aquatic life.

Sexual Frustration Harms Health and Leads to Premature Death in Fruit Flies

Sexual Frustration Harms Health and Leads to Premature Death in Fruit Flies

As per a latest study, sexual frustration can harm the health of fruit flies and can also lead to premature death.

Scientists have found that flies that are encouraged to mate but are prevented to do so, the life of such flies get shortened by up to 40%. However, flies that are allowed to mate live a longer and lead a less stressful life.

The study is published in the Journal Science. In the study, flies were put in close proximity to genetically modified males who had been transformed to discharge female sex hormones, pheromones.

A research has taken place in which study researchers have tried to explain the reason as why some primates have complex facial features and have different colors and other primates adorn simple faces.

The research carried out by a group of researchers from UCLA has found that Old World monkeys and apes are part of bigger groups. Therefore, they have more complex features and are of different colors.

But such is not the case with primates who belong to smaller groups. This forms to be the reason that they have simple faces and are of fewer colors.

Olaf Thalmann from the University of Turku in Finland led a team of researchers which used prehistoric genomes find that European hunter-gatherers transformed wolves into friendly Fidos around 20,000 to 30,000 years ago.

This new finding has started a fresh debate on the age old topic going on among researchers for years now.

500-Year-Old Clam Accidentally Killed by Scientists

It has been revealed that a 500-year-old clam was killed mistakenly by scientists after it was taken by them for additional research. It happened after a field trip that was conducted by the School of Ocean Sciences in 2006, which helped scientists figure out the age of the clam.

The research was part of a project to gain insight into climate changes over the last 1,000 years. According to reports of USA Today, the creature was alive until the day researchers cracked its shell open for research purposes. But the clam was found dead after that.
