Huge Insects in the world

ScienceDaily (Aug. 8, 2007) — Alexander Kaiser, Ph.D., of Midwestern University’s Department of Physiology, Division of Basic Sciences, was the lead author in a recent study to help determine why insects, once dramatically larger than they are today, have seen such a remarkable reduction in size over the course of history.

There were hundreds of ideas to explain the small size, but none of them could be proven,” Dr. Kaiser said. To test their theory that it was an insect’s respiratory system that limited its size, he and his colleagues launched an extensive study using beetles and fruit flies.

The study, much of which was performed at Illinois’ Argonne National Laboratory, involved the examination of various beetles’ respiratory systems, using new x-ray beam technology to help determine how they breathe.

Findings show that Dr. Kaiser and his colleagues are on the right track in their theorizing. Insects breathe through a network of air filled tubes that deliver oxygen directly to the cells. These tracheal tubes, especially in the leg, take up more room in larger beetles.

“More than 300 million years ago, there was 31 to 35 percent oxygen in the air,” Dr. Kaiser said. “That means that the respiratory systems of the insects could be smaller and still deliver enough oxygen to meet their demands, allowing the creatures to grow much larger.”

Bear Attacks on man

How to stay safe in bear country

Many people like to enjoy nature closely, by hiking in backcountry and mountainsides. But when you are in bear country, you should be careful and prepared.
Bear Safety Tips:

• Make lots of noise. Especially important when you are on a trail with restricted visibility, as well as those times when the wind is blowing towards you, meaning that bears will not have the benefit of your scent. What is most important is for the bear to hear your approach long before you are within its personal space.
• Travel in groups. Groups of people tend to make more noise, therefore reducing the chances of a bear encounter. Largeer groups offer the added benefit of appearing much more threatening and thus less likely to attract a bear attack.
• Stay alert! Even though you may be making noise, it is still important to stay alert and on the lookout for bears. Most bear attacks occur when the person was not aware of the bear's presence until the bear was less than 50 m (164 ft) away.
• Always carry bear spray, and make sure that it is quickly accessible. It will be useless if it is buried in your pack. Practice quickly getting it out and preparing to spray. Bear sprays are an effective deterrent in very close range, emergency situations. When you find yourself in a situation where bear spray becomes necessary, you better be able to pull it out and activate it with little or no notice. It should be on your belt, and you should practice drawing it quickly.

If you see a bear, stay calm and give it plenty of room. Do not startle it; detour slowly, keeping upwind if you can, so it will get your scent and know you are there. If you can't detour wait until it moves away from your route before proceeding.

When a bear first detects you, it may stand upright and use all of its senses to determine what and where you are. Once it identifies you it may ignore you, move slowly away, run, or it may charge. A wild bear rarely attacks unless it feels threatened or provoked.

On four legs, a bear may show agitation by swaying its head from side to side, making huffing noises and clacking its teeth.

A charge or retreat may follow. Flattened ears and raised hair on the back of the neck indicate aggressive intent. If a bear runs with a stiff, bouncing gait, it may be a false charge.

World's Most Dangerous Roads

The Death Road (Bolivia)

The North Yungas Road, also known as The Death Road, is a 61 to 69 km road leading from La Paz to Coroico (Bolivia's capital, to the Amazon region) in the Yungas region of Bolivia. It is legendary for its extreme danger: in 1995 the Inter-American Development Bank christened it as the "world's most dangerous road. " One estimate is that 200-300 travelers were killed yearly along the road. The road includes crosses marking many of the spots where such vehicles have fallen.

Guoliang Tunnel Road (China)

The road in Taihang mountains was built by local villagers: it took five years to finish the 1,200 metre long tunnel which is about 5 meters high and 4 meters wide. Some of the villagers died in accidents during construction; undaunted, the others continued. On May 1, 1977, the tunnel was opened to traffic. It is located in the Taihang Mountains, in the Hunan Province of China.

Trollstigen (Norway)

Trollstigen (The Troll Ladder) is a mountain road in Rauma, Norway, part of Norwegian National Road 63 connecting Åndalsnes in Rauma and Valldal in Norddal. A popular tourist attraction due to its steep incline of 9% and eleven hairpin bends up a steep mountain side, the road up is narrow with many sharp bends, and although it has been widened in recent years, vehicles over 12.4 meters long are prohibited from driving the road. At the top there is large parking place which allows visitors to leave their cars and walk for about ten minutes to a viewing balcony which overlooks the road with its bends and the Stigfossen waterfall. Stigfossen is a beautiful waterfall which falls 320 meters down the mountain side.

Stelvio Pass Road Trollstigen(Italy)

The highest paved mountain pass in the Eastern Alps --and the second highest in the Alps, after the Col de l'Iseran (2770 m)--, the Stelvio Pass Road connects the Valtellina with the upper Adige valley and Merano. It is located in the Italian Alps, near Bormio and Sulden, 75 km from Bolzano, close to Swiss border.

While it might not be as risky as other deadly routes, it's certainly breathtaking. The tour books advise that the toughest and most spectacular climbing is from the Prato side, Bormio side approach is more tame. With 48 hairpins, this road is regarded as one of the finest continuous hairpin routes in the Alps.

An education section covers robotic resources for teachers along with details of our school incursion programs, after hours programs and our new corporate training programs. Our links section lists hundreds of informational and exciting robotic websites and our gallery will take you on a robotic journey. Today, the robot is one of those predictions that has come to pass, but only in that "Well, sort of" kind of way. We have thousands of robots in our factories turning out everything from cars to electrical tooth flossers. Japan is positively stinking with them (robots, not tooth flossers). Not to mention all the mechakaiju giant robots that stomp Tokyo periodically, if Japanese cinema is anything to go by. But these robots aren't what we had in mind. The robots of today are all basically descendants of Unimate; the one-armed industrial robot of the '60s. They're programmable machines that carry out a specific sequence of tasks time after time without error or deviation. For example, a robotic palletizer in the packaging industry. They're incredible machines and the latest models incorporate a remarkable range of sensors and artificial intelligence software, but to the uninitiated they look very little different from the other factory machines that surround them. Not like this illustration of a factory humming with anthropomorphic workers busily handling lathes and stamping mills.

Arrival of planet NIBIRU

The Planet NIBIRU

The Nibiru collision is a disastrous planetary collision between the Earth and a large planetary object which certain subcultural groups believe is going to take place in the near future. Believers refer to the large object with which the earth will supposedly collide variously as Nibiru, Planet X, or Wormwood.

The idea was first proposed in 1995 by Nancy Lieder, founder of the website ZetaTalk.[1] Lieder describes herself as a contactee with the ability to receive messages from extra-terrestrials called Zetas (from the Zeta Reticuli star system; see Betty and Barney Hill) through an implant in her brain. She states that she was chosen to warn mankind that the object would sweep through the Solar System in May 2003 (later revised to around 2010), causing a pole shift that would destroy most of humanity.

This idea has subsequently spread beyond Lieder's website and has been embraced by numerous internet doomsday groups, most of which tie the collision to the 2012 doomsday prediction. The idea that a planet-sized object could possibly collide with Earth in the near future is not supported by any scientific evidence and has been roundly rejected as pseudoscience by astronomers and planetary scientists.

Clipta - new video wave: 2012 SIGNS- PLANET NIBIRUS ARRIVAL

Scientific criticism

The Nibiru collision idea fails on several basic scientific grounds. For instance, such an object so close to Earth would be easily visible to the naked eye (Jupiter and Saturn are both visible to the naked eye, and are dimmer than Nibiru would be at their distances), and would be creating noticeable effects in the orbits of the outer planets.^[37] If this object's orbit were as described, it would only have lasted in the Solar System for a million years or so before Jupiter expelled it. Also, there is no way another object's magnetic field could have such an effect on Earth.^[38] Lieder's assertions that the approach of Nibiru would cause the Earth's rotation to stop or its axis to shift violate the laws of physics; the energy required to do either would be enough to destroy the Earth completely.^[39]
