Ancient terrain found on Atlantic seabed
July 13, 2011
Researchers have discovered a 56million-year-old lost terrain submerged beneath the North Atlantic in the west of the Orkney-Shetland Islands while analyzing data collected for oil companies.
The 3D image of the landscape developed using an advanced echo-sounding technique shows how the North Atlantic would have looked around 56million years ago, Science Daily News reports.
The hi-tech echo sounding technique releases high-pressured air as well as sound waves that pass through sediments on the ocean floor. The echo is then gathered by a microphone being dangled deep underwater from a ship travelling on the ocean’s surface, according to the article published in the journal Nature Geoscience.
Likened to the mythical lost city of Atlantis, the 1.2mile-deep landscape has several peaks indicating that it may once belonged to mountains and even eight major rivers, the researchers suggest.
It is like an ancient fossil landscape preserved beneath the seabed, said the researcher Nicky White, from University of Cambridge.
Submerged beneath the North Atlantic Ocean, the landscape would once rise up to 0.6 miles above sea level and then join up with Scotland. It may also even expand to Norway, the scientists claim. FGP/PKH Source: presstv.ir

Dirty socks 'could help fight malaria'
July 13, 2011
The odor of dirty socks can be used to lure mosquitoes into a deadly trap before they can spread malaria, a US and Canadian-funded researcher based in Africa said Wednesday.Dr. Fredros Okumu, of the Ifakara Health Institute in Tanzania, discovered through an experiment that mosquitoes were more attracted to the odor of filthy feet than to live humans sleeping in the same area.
"We had an experimental house with a human being sleeping inside and a second experimental house with a synthetic mixture," he told AFP by telephone."We realized that we were getting four times more mosquitoes going into the house with (the) synthetic mixture," which, when doused with insecticide, killed the bugs.
"When mosquitoes are crossing the compound, they sense something that they think it is a human being. They attempt to bite that person or that device and... instead of getting blood they get killed."
His findings have earned him a $775,000 grant from the Bill and Melinda Gates Foundation and the Canadian NGO Grand Challenges to install the devices in a number of Tanzanian villages to measure their effect on public health.The devices are to be placed outside homes in order to complement life-saving nets and repellents

"We were attracted to that idea because it is a bold idea, it's creative, it's innovative," Peter Singer, Chief Executive Officer of Grand Challenges Canada, told AFP.
"Who would have thought that a life-saving technology could be lurking in your laundry basket?"
Malaria claimed 781,000 lives in 2009, according to the UN's World Health Organisation (WHO), which is heading efforts to distribute insecticide-treated mosquito nets and to spray reproduction sites.
About 90 percent of malaria deaths each year occur in Africa and 92 percent of those are children aged under five.
Other mosquito-borne diseases include dengue, which sickens around 50 million people each year, yellow fever, filariasis and West Nile virus.

Billions of bugs wiped out on Dutch roads
 |
| How much did you kill today? |
Dutch motorists kill about 133 billion insects a month, splattering bugs on their vehicles and eliminating important members of the food chain, according to a study released this week
Biologists at Wageningen University in the Netherlands enlisted the help of 250 drivers for a "splash teller" study. Each motorist had to wipe his or her car license plate clean then tot up the bug body count at the end of their drive.
"They are by far the richest species groups in all countries, and therefore play an essential role in the food chain," biologist Arnold van Vliet, one of a team working on the project, told Reuters.
Insects are not only important pollinators of commercial and wild plants, but also form a crucial part of the diet of many animals including birds and bats.
The study showed the most dangerous parts of the country for a flying insect are the coastal provinces of Zeeland, Friesland and Groningen -- which Van Vliet said was possibly a reflection of the fact the human inhabitants are more likely to drive longer distances in these less densely populated areas.
Van Vliet said the scientific study was inspired by a similar project in the United Kingdom, carried out in 2004.(Reporting by Jennifer Martin; Editing by Sara Webb)
