The Google doodle honors this Saturday the 46 years of the American TV series Star Trek in Brazil – originally broadcast on 8 September from 1966 to 1969. Google changed the letters of his name in characters of the program, and the logo is interactive and allows you to create a story by clicking on some items. Clicking on the door,...
Who uses Google every day, are tired of knowing that the company’s brand becomesholidays. today (01/05) was no different: to celebrate Labor Day (or Labour Day), the Mountain View giant displays a special doodle. The date is celebrated in many countries worldwide and was created in honor of an event which happened in...
Every human being can make mistakes, even the geniuses never forget that. remember that even albert einstein, had made mistakes Some of them were very serious and did the job of the scientist to stand still for more than three years (until all the points were finally balanced). Check out now some of the biggest mistakes...
Police in the municipality of Chatham-Ken, Canada, released a curious ranking . The service divided the 1,986 people arrested in 2011 in the area by signs, and found that the Aryans are the majority among those who committed crimes this year. Second are Libras, followed by Virginians. Sagittarians were the least out of the line.
Check out the signs of division among the 1986 prisoners:
Aquarius: 142
Fish: 169
Aries: 203
Taurus: 146
Gemini: 159
Cancer: 147
Leon: 177
Virgin: 183
Libra: 189
Scorpio: 166
Sagittarius: 139

The image above, recorded by the photographer Bill Snyder space, shows what happens after the explosion of a star. The gas released by the explosions is illuminated by what remains of the center of the star, and the cloud of dust will be expanding and erasing until there’s nothing left. The picture serves as a preview of what will happen in five billion years when our Sun must undergo a similar process.
The explosion of stars gives rise to nebulae. The image above its called Dumbbel Nebula, which is approximately 1360 light years from Earth. Calculations that show the time needed for light to reach from there to here indicate that the process of detonation of the star began between 3 and 48 thousand years ago.
In the United States, it is forbidden to use electronic devices during takeoffs and landings on commercial flights. The claim is that this practice may result in interference to aircraft. But a test commissioned by Bits technology blog of U.S. newspaper New York Times, contradicts the official statement of the Administration of the U.S. Federal Aviation Administration .
The tests were performed by EMT Labs and measured the emission of electrical appliances during use. The Kindle electronic book reader from Amazon, emits less than 30 microvolts per meter while running, which is well below 100 volts per meter of interference that a plane must support to be approved by the FAA.
“The energy that comes from a Kindle is quite tiny and can not interfere with a plane,” says Jay Gandhi, chief executive of EMT Labs. When asked if multiple Kindles and iPads running simultaneously would not give rise to interference, Gandhi is emphatic: “electromagnetic energy does not work well. Five Kindles will not emit five times more energy than one, “says the executive.
The hypothesis is confirmed by Bill Ruck, chief engineer at CSI Telecommunications, engineering company responsible for radio communication. “To say that 100 devices are 100 times worse is factually incorrect,” while ensuring that interference emitted from the devices decreases when more units are activated in the same range.
Maybe with this we hope that the mister Alec Baldwin don’t cause any problem in the future.
Researchers at the Albert Einstein College of Medicine in the United States, announced this week the discovery that the human body is programmed to destroy itself in extreme situations. The explanation is in the process of protein synthesis.
The RNA Messenger is responsible for bringing the information from DNA to turn them into proteins. According to scientists, in some cases RNA can stop the process, failing to bring this information forward, which causes the cells do not reproduce or regenerate.
The research focused on two genes, SWI5 and CLB2, which encode proteins and help regulate cell division cycle, when there is duplication of genetic material for further distribution of it between the two daughter cells.
If it is possible to identify and control the way the RNA Messenger reacts, the expectations of medical therapies is to propose regulation of uncontrolled cell division that characterizes cancer. The study is still ongoing and there is expected to be completed.
Anyone who has looked at the Ministry of Health warnings on cigarette packets were frightened by the warning about the dozens of carcinogenic compounds in the product. However, what few people know is that among the various types of materials harmful to health present, there are radioactive elements.
And this is not something recent. Since the ’30s, the tobacco industry uses a fertilizer made from apatite, a mineral that is responsible for expensive special taste of the cigarette. The problem is that to create the phosphate used in the planting of grass, the stone remnants releases of polonium, uranium, bismuth and various other materials that emit radiation.
This causes the substances also reach the final product being released in the smoke, and consequently the air. Thus, even passive smokers end up being victims of “radioactive attack.” This is because the molecules stick to harmful material in the lung tissue and other organs, damaging cells. At first it may seem like something that does not deserve attention, but the weather can be more serious about it.
The presence of apatite is just one of the reasons that make cigarettes so harmful to health. In addition, American institutes, such as the Environmental Protection Agency, struggling to disclose such information and alert the public about the type of material they ingest daily.
To prove the dangers of radiation present in the smoke, the National Council on Radiation Protection and Measurements has made an interesting comparison. It said if a person is exposed to an X-ray machine, she gets an 8 mrem of radiation. On the other hand, a pack of cigarettes has about 29 mrem. It’s like if you made more than three radiographs in one day.
A metal ball weighing about 6 kg fell from the sky and landed in Namibia, a country located in Southern Africa. It happened in November, and soon after it happened, authorities contacted NASA to seek an explanation about the incident.
According to the U.S. agency, the iron ball is possibly space debris has fallen off the Earth’s orbit. According to calculations by NASA, the chances of a person being hit by space debris are 1 in 3200. Since launching the first space satellite, there is no record of death in these terms.
Major component of the Earth’s core, the iron oxide surprised a team of scientists at the Carnegie Institution for Science, when exhibit an unexpected behavior. After being subjected to extreme pressures and temperatures, the material changed the degree of electrical conduction.
When subjected to conditions similar to those presented in the Earth’s interior, much of the evidence shows dramatic changes in their properties, which are always accompanied by changes in the structure of the material.
What surprised scientists was that the iron oxide to keep its structure intact and still make significant changes in their electromagnetic properties. This finding may help to better understand how Earth’s interior gives rise to the planet’s magnetic field.
How the experiment was done
In the laboratory, the team at the Carnegie Institution for Science submitted the iron oxide pressures that reach 1.4 million ATMs (Earth’s atmospheric pressure) at sea level and temperatures of 2200 ° C, conditions similar to those found in lower layers of earth.
What they found was that the material can function both as insulation and as a driver just by changing the pressure and temperature. Using computer simulations to understand what was happening to the electrons in the material, the group obtained results show that a new type of metallization.
Even mixed with magnesium (basic composition of the mantle), iron oxide continues to conduct electricity. The fact that this material behaves like a metal means that it electrically connects the Earth’s core to the upper layers. This greatly affects the way in which the planet’s magnetic field is generated.
Although many questions have arisen with this discovery, the science is getting closer to understanding what really happens in the lower layers of our planet.
The purpose of this study was to understand how the miniaturization of species affects the brain and behavior. ”We found that the central nervous system of the smaller spiders come to fill up to 80% of body cavities, including about 25% of the legs,” says William Wcislo,staff scientist at the Smithsonian Tropical Research Institute.
By comparison, the human brain represents only 3% of our body mass. Some of the brainsstudied, such as an ant, can mean up to 15% of its biomass. By proportion, it is likely that much of the energy consumed is allocated to this region of the body.
Take Google’s total revenue in 2010. Now, together, add the GDP of the 28 poorest countries in the world? such as East Timor, Guinea-Bissau, Belize, Bhutan, Sierra Leone. Believe me, the safe search engine is more full than all of them together.
An infographic joined this and other various information about Google, the source of their money, the amount of people accessing their sites and even how much energy the company uses to move all of this wheel.
Google pulled in $ 29.3 billion in 2010. Accounts for 97% of the pie is the result of all ads. About $ 2.5 billion of total income came only from ads on mobile platform and the belief is that this number goes double this year.
Google AdWords, the search engine listing service, charge dearly for the use of certain keywords (which will cause the ad to appear in a larger amount of searches). The most expensive in English would be ‘safe’ (1), ‘loans’ (2), ‘mortgage’ (3), ‘lawyer’ (4) and ‘credit’ (5).
Finally, Google has about 1 billion unique hits monthly. It is as if one person every seven in the world entered the site at least once a month.
They may appear to daydream of a movie character who is trying at any cost to become an immortal being, but two different surveys in progress are aimed at an extremely difficult task: to discover the secret of immortality.
In general, the human being dies due to aging of cells or organ failure. So what if we could stop and replace the aging organs before they both can compromise our health?
Aubrey Grey, a Cambridge University researcher, was able to isolate an enzyme from bacteria, keeping them suffocated and preventing them from dying. Grey believes that the process can be accomplished in human cells, provided that the same enzyme is isolated.
Since molecular geneticist Bill Andrews found a supplement that maintains telomeres, a kind of DNA bands at the end of the chromosomes are shorter. Thanks to this, the researcher believes that it can control the deterioration of cells, reversing the aging process. Will any of them able to be successful in your research?
