Ink extracted from a 155 million years Squid

In some rocks of Wiltshire, England, paleontologists have found a fossil of a squid-like mollusk, some 155 million years old, preserved in such a condition that could be extracted even some ink stored in his inside.

The specimen of Belemnotheutis antiquus has been described as "one of the best preserved fossils of the world." Phil Wilby, coauthor of the discovery, explains that everything is due to the so-called "Medusa effect" which occurs when specimens become stone in question of days, before damage to their soft tissues.

The ink sample is being analyzed at Yale University to obtain a more complete chemical analysis. So far the researchers have already used, mixing it with an ammonia solution, to draw a sketch of prehistoric mollusk.

The girls prefer Geeks

Regardless for the famous series of films of the nerds whom do not usually have much luck when it comes to conquering girls. However, if is of them, at least there is a scientific study that shows just the opposite: at least on paper we are the Nerds Casanovas.

A study at the University of Elon, North Carolina, showed a group of women a series of videos from different subjects performing both athletic and intellectual. The tasks themselves were not so obvious as to discriminate against those who were more consciously smart, but when at the end of the test were asked by the ladies more attractive subjects, showed that instinctively tended to elect more intelligent than before the most athletic. ¿Natural selection? Perhaps, but it must be right that they were not nerds (suspensores, trousers up to the navel and thick glasses), but rather geeks (a bit more produced). Now the only thing we need is to find the women of the study, because I know always choose the head of the muscle.

My personal theory is that, indeed, may end up marrying the nerd with the most beautiful girl in the school, but that happens when you have 30 years and she was dating all muscled fellow.

Bad breath and how to avoid it

If we take a look at PubMed, a database of current scientific papers, we find some interesting articles. Everyone agrees that most of the possible causes of halitosismal encouragement are located in the mouth. Secondly, there are respiratory infections and Otorhinolaryngologic. And lastly, there are processes (diabetes, for example), liver or kidneys (the hand to lift the medical student who is not sick of hearing the blessed frasecita "fetor uremic). We must also bear in mind that certain medications can dry the mouth or change the bacterial flora of the mouth, halitosis encouraging.

Let us not delude ourselves: many halitosis is easily solved with proper oral hygiene. A good brushing after every meal that includes all the teeth (not just luster to get the front to have a bright smile) for the required time and a mild mouthwash to help remove enough food which when processed by the bacterial flora mouth compuesos emit volatile sulfur compounds that give the smell. I repeat that the mouthwash should be smooth and you can not abuse it, because most often as they contain alcohol and dry mouth.

It also helps keep a balanced diet with enough fruits and vegetables, drinking water in quantities sufficient to prevent the saliva espesamimal alientoento and can not fulfill their duties. Following this, remember that all who follow the Atkins diet or an unbalanced diet that will take a breath pull back (the explanation is that the ketone bodies that are formed as a result of the use of fat for energy compounds are very volatile and with a very characteristic odor). Of course when I talk about fruit and vegetables do not include onions and garlic, "Whoever eats garlic talk down", nor should we forget some other foods like cheese and coffee are adhering to teeth and mucosa mouth, being an excellent raw material for bacteria to get spiked "putrificar" and the blessed release volatile sulfur compounds.

What about the "social services"? Because the alcohol dries the mucous membranes and alters the bacterial flora and odorous substances such as snuff contains nicotine which are impregnated in the mouth. Nothing can be arranged with a good toothbrush.

If you still keep a good hygiene and proper diet the problem persists, it's time to go to the dentist to rule out problems in the mouth, as a periodontitis. What if the dentist out any pathology? The appropriate approach is to go to the doctor to determine the cause and remove the most frequent pathologies according to the signs and symptoms of the disease besides the bad smell of breath. Again, we can go to much trouble for this consultation, but many times the bad breath is an excellent sign that guides us on various diseases, not in vain, we spent a career studying such things as "the smell of green apples diabetic ketoacidosis" "fetor liver, fetor uremic", recognizing the smell of a lung abscess in practices and a long etcetera.

The high-tech sneakers of Usain Bolt

Usain Bolt is one of the highest performing athletes in the world, is the fastest man on the planet. Period.

For the twelfth edition of the IAAF athletics championships, the German brand PUMA has developed a shoe called Yaam with the latest technology and custom foot Bolt. Have a weight of only 149 grams, the base is constructed of carbon fiber, resulting in lightweight and flexibility of the shoe that Bolt is equal to greater momentum and traction with each step.

The decor is not random, since it is based on the art of Jeff Koons, and orange colors were intended to contrast with the blue track of the Olympic Stadium in Berlin on Sunday where Bolt broke the 100m world record levels.

The price? Very expensive, but Puma will sell to the rest of us a shoe that is call Yaam Street.

The U.S. Navy wants jets deployed with sea water

Military inventions are not exactly something that excited us. However, it is undeniable that one of the major pathways of technological development is guided under the purview of the arms industry. Making many advances in technology and military materials of interest as the last experiment of the Navy of the United States, which aims to use sea water as fuel for its jets.

In fact what it purports Heather Willauer, who is leading the project is to generate a hydrocarbon fuel based on removing carbon dioxide from sea water and combined with hydrogen. So far they have managed to create unsaturated hydrocarbon chains due to a system based on the Fischer-Tropsch process.

What is striking about this development is that, besides having the potential to revolutionize logistics systems associated with the jet fighter, its application in civil aviation would reduce operating costs and benefits to all users. However, there is rejoicing as soon as it is only a project and reach out to civil purposes is not assured.
