what's the buzz


While rising temperature are predicted to cause the melting of ice, rise in sea level, heavy storms and rainfall, the Earth’s crust can be affected by all these phenomenon.
Even minor changes in the environment could spark off earthquakes and tsunamis.
Bill McGuire, University College London, warns that warming temperatures could melt ice sheets and glaciers, thereby increasing the water content of oceans.
As the land ‘rebounds’ after the weight of the ice has been removed — which could be as large as a kilometre in places like Greenland and Antarctica — then if, in the worst case scenario, all the ice were to melt, it could trigger earthquakes.

Resting fat people not lazier than slim persons
When a slim person is seen laying down watching TV, people assume they’re resting. But when people see a fat individual relaxing, it’s automatically assumed they’re lazy and unmotivated.
Now, Tanya Berry, Faculty of Physical Education and Recreation, says these stereotypes about overweight people need to be addressed. According to her, just because a person is overweight, it doesn’t mean they don’t exercise, and just because a person is thin, it doesn’t mean they are fit and healthy.
In the University of Alberta research, Berry had a group of study participants look at a number of pictures that would flash on a computer screen. After each photo a sedentary word such as ‘lazy’ would appear.
After the participants looked at each picture they were asked to say the colour of each word. Berry says when a picture of a thin ‘couch potato’ came up, the participants were quick to say the colour of the word that appeared. But when a photo of an overweight person lying down appeared, the study participants paused.
Berry concluded that the slow reaction resulted as the stereotyped thoughts automatically set in, with the participant thinking about the person being lazy rather than thinking about the colour of the word.

Men’s apologies could improve women’s health
Scientists claim, when a man refuses to apologise to a woman for something wrong he has done, he could put her at risk of a heart attack.
A study found that women who are starved of an apology for rude or hurtful behaviour suffer an increase in blood pressure, which can raise the risk of a heart attack or stroke.
Research at the University of Massachusetts showed that those who hear a well timed ‘sorry’ calm down more quickly, with their blood pressure returning to normal 20 per cent faster. On the other hand, a man’s blood pressure takes 20 per cent longer to recover after an apology — suggesting men become more worked up after hearing an admission of guilt.
Scientists measured the diastolic blood pressure of 29 men and 59 women throughout the experiment.
