Mosquitoes like my blood

Written by Khalil A. Cassimally

Here in Mauritius, mosquitoes are in paradise. The male mosquitoes have allrepparttar fruits they’ll ever dream of – god knows whether they actually dream – all year long whilerepparttar 105813 female mosquitoes can choose from a numerous number of tourists to feed on.

It is of no surprise that tourists get bitten more than we, locals do. Andrepparttar 105814 reaction which occurs onrepparttar 105815 tourists’ skin is quiet unusual to me. A large red swelling develops. It is about twicerepparttar 105816 size thatrepparttar 105817 one which would have formed on my skin if I was to get bitten. Apparentlyrepparttar 105818 bite that a tourist receives is also more irritant. In my opinion, this is because foreigners are not as used to get mosquito bites than Mauritians do. But one thing is for sire though: some people do get bitten more than others.

Why is this so? Or rather, why are some people bitten less? James Logan, a research student atrepparttar 105819 Biotechnology and Biological Sciences Research Council (BBSRC) has found that some people give off ‘masking’ odours that prevent

Staying Safe When There's Lightning Around

Written by Graham McClung

Lightning is great to watch, and makes a superb subject for videos or photographs - from a distance. But it's pretty scary when it strikes nearby, and every year there are news reports of lightning fatalities.

So what are your chances of being struck by lightning?

Fortunately they are pretty slim. But that's probably whatrepparttar hundred or so people killed by lightning in an average year probably thought.

So while you or I are most unlikely to be struck,repparttar 105812 consequences are so severe that it's worthwhile taking every precaution to make sure that we don't end up a lightning statistic.

A Few Lightning Facts

  • Although lightning is known from volcanic eruptions and in smoke from very large fires, it is always present in thunderstorms, and thunderstorms can occur anywhere and at any time of year. Inrepparttar 105813 US they are most common in Florida and nearby states, and overall are most frequent from April to July. Lightning fatalities are most common in July, probably because more people are out of doors at that time of year.

  • Lightning is a very high voltage electrical discharge, with its source in a thunder cloud. Most lightning moves between clouds, or from cloud to air. The cloud to ground strikes are rarer, but arerepparttar 105814 ones to worry about.

  • Apart from floods, lightning causes more deaths than any other severe weather event, including tornadoes and hurricanes. Figures are not precise, but around 100 deaths occur in an average year, while injuries are at least ten times that number.

  • Lightning injuries are most common before and after repparttar 105815 storm has passed over - before and afterrepparttar 105816 rain, winds and hail have caused people to take shelter. Another reason is that lightning bolts can travel distances of over 10 miles (16km) fromrepparttar 105817 cloud before hittingrepparttar 105818 ground.These "bolts fromrepparttar 105819 blue" may arrive before any thunder fromrepparttar 105820 storm can be heard, and even beforerepparttar 105821 storm clouds have been noticed.

  • Deaths and injuries occur most commonly to outdoor workers, hikers, campers, and people involved in outdoor sport or picnics, including sporting teams. Quite often,repparttar 105822 victims have delayed finding shelter untilrepparttar 105823 last minute.

Deaths and Injuries

A lightning strike is a very short lived, high voltage electrical current, but has different effects to a home or industrial electric shock. Most lightning fatalities are instantaneous through failure ofrepparttar 105824 heart or breathing, or severe nervous damage.

Lightning deaths and injuries can occur in two ways - by a direct strike, or indirectly from being within about 50 yards ofrepparttar 105825 strike. A short-lived electric current can travel through damp soil, wet grass, water, and along fence wires, plumbing or underground cables. This explains deaths or injuries to people who are indoors but in contact with telephones, electrical appliances or plumbing fixtures.
