Found, Oldest Spider Net

Fine net spider made about 140 million years ago was found preserved in amber. Nets are found in Sussex, England, was preserved when the sap of resin before it hardens and wet stone. In the same stone was also found in the rest of the plant, insect droppings, and ancient microbes.

"This is a spider web of the oldest ever found by our fossil record," said researcher Martin Brasier of Oxford University, Saturday (31/10).

Brasier and colleagues using a computerized technique called confocal microscopy to reconstruct and examine the net and knot. Some things, including the nodes which are connected using a sticky fluid, indicates that the net was made by a spider that is related to spiders modern garden.

"This spider is also placed along the sticky nets to trap their prey," Brasier said. "The remains of the sticky liquid come preserved in amber.

The analysis of these nets also provide clues about the food of spiders. I think, based on web forms, this animal preys on flying insects such as flies and bees ancestors, wasps, and beetles, "Brasier said.

In 2006, the researchers found cobwebs are also preserved in amber. He was about 136 million years. Read More......

DNA Can Motivate Ourself

Deoxyribunucleic Acid (DNA) has always been known to identify lineages. In fact, DNA not only can be learned from the medical side. Psychologist Miriati, Psi, express, DNA can also be highlighted from the science of Psychology. What are the benefits? Apparently, the DNA can be optimized to generate your own potential. Want to know, how to activate the DNA?

How to enable DNA to potential?

There are several ways to activate the DNA. Miriati explained, at least there 6 positive character can be grown in every individual. First, open up to absorb a broad perspective. Broad insights will stimulate desire. Second, the desire or dreams, can generate positive energy in yourself.

Not only from yourself, can also turn distimulus DNA from the surrounding environment. The third way, inspiring moments encountered.

"One can rely on his own with what is in him. Everywhere, we can inspire the origin of life presents consciousness so that we can make sense of an event," he said.

Fourth, always think positive, grab it first and do it! That is, always thinking positive for any new opportunities. And fifth, always doing exercises that continuous activation of the DNA will be generated spontaneously and positive implications for the potential.

Miriati also warned, if you have a dream or desire, share with the people who are believed to be able to give encouragement. Positive encouragement would spur obtained active DNA. "Do not tell the same people who have not been put before your spirit," said Miriati. Read More......

Large meteor explosion in the Netherlands

Hundreds of people in the Netherlands and Germany reported seeing a fireball shot across the sky at dusk, around 7 o'clock local time.
Robert Mikaelyan amateur photographers to get pictures of rare when a large fireball exploded in the sky. The incident happened shortly after he came out to take photos of the old sugar factory Netherlands.

Mikaelyan managed to get a picture a few shots of the fireball swinging low over the northern city of Groningen, before finally breaking into pieces smaller.

"I suddenly saw the light in the sky came quickly ... and rushed to get a picture," said Mikaelyan.

A few seconds after the fireball had been seen, the witness heard an explosion followed by a low rumble that shook the windows.

The object is most likely the space rock that shattered after hitting the earth's atmosphere, said experts who also speculated that the pieces of the meteor may land on the North Sea.

"This is a big event," said Theo Jurriens, the Kapteyn Astronomical Institute at the University of Groningen.

At present the earth constantly bombarded by debris smaller than comets, asteroids, and even the other rocky planets in the solar system.

But the ball of fire with such size and bright light may be visible only every 20 to 25 years, Jurriens estimate. Read More......

URINE Is New energy

Increasing depletion of oil reserves for fuel, made of experts around the brain to develop renewable energy sources. Now, there are recent findings that allow a motor vehicle fuel be replaced by the urine. Scientists have created a catalyst that can extract hydrogen energy sources originating from urine.
Catalyst not only can be a source of energy for hydrogen-fueled cars in the future, but also can help clean the environment, especially in the handling of waste water. Such information is quoted from the Times of India, Friday (10/7/2009). Gerardine Botte and his team from Ohio University utilize elektrolik approach to produce hydrogen from the urine. Substances urine is the most abundant waste in the world largely composed of elements of urea. Meanwhile, urea is a potential element to serve as hydrogen. In each molecule of urine, there are four hydrogen atoms joined to each other. Hydrogen atoms in the urine is stronger than the hydrogen atoms in water molecules. Botte and his team use electrolysis to separate these molecules, to develop nickel-based electrodes to oxidize efisien.Selama urea in the electrochemical process, urea is absorbed by the nickel electrode surface and the electron flow is needed to break down molecules, "Botte said. To break the molecules , the electricity required by 0:37 V. The element for separating water, require less electrical energy than 1:23 V.

What is the biggest threat in the world today? If you answered swine flu or bird flu, a big one ..

Medical journal The Lancet and the researchers from University College London, UK, concluded that climate change is the biggest global health threat in the 21st century.
They agreed, public health services also have to adapt. What to do? Apparently, the world adapt to the increasingly warmer temperatures. This is the key to global health infrastructure improvements. Because many diseases are affected by the global climate. For example the series of viruses that is currently more vivid.

"We must act immediately to save billions
lives. We try to spread this message throughout the world, "said climatological Lecturer University College London (UCL), Mark Maslin, as reported by the BBC.
Researchers agreed to emphasize the issue of carbon mitigation and explain in more detail how the global climate change affects the health of the world. They intend to voice this message to the more vocal to the politicians and policy makers. "We must make a priority now. What we do will be very influential. Start of conference calls on climate change issues, writing, collecting evidence, and much more. Change your policy through science," said Lancet editor Richard Horton.
