Intelligence of children weakened by lead A survey conducted on over five hundred children in the South Island of New Zealand in the city of Dunedin would have shown that in the period between 1970 and 1980, when gasoline was added with the lead (used to lubricate the engine, improve combustion and therefore the performance), children who were exposed to the vehicles exhaust fumes had to have at age thirty-eight an intelligence quotient and a social standing lower than peers who had undergone a minor exposure. In 1984 when blood collection was made to children in Dunedin just a level above thirty-five micrograms of lead per deciliter of blood carried to an alert to medical staff, a very large amount compared to five to ten micrograms which later were starting the alert for preventive controls. In 1996 the petrol with lead was banned in New Zealand. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Mar 31, 2017

Confirmation that birds derived from dinosaurs Examining the fossil from one hundred twenty-five and one hundred forty-five million years ago found in China and belonging to a bird exceptionally well preserved, English and Chinese researchers have noted that had a more straighter posture than that of crouched type that can normally observe in birds; in fact the anatomy of cartilages and tendons would show that primitive birds had an ankle complied with so as to make possible movements which can be considered as intermediate between those of dinosaurs and modern birds. This fossil of "Confuciusornis" fossilized in volcanic ash has allowed to observe anatomical details up to the molecular level of the tissues and ligaments of the ankle joint confirming the hypothesis that the posture of the birds is derived slowly from that of the dinosaurs. Other studies suggest that some birds may have its own lineage. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Mar 25, 2017 n°: 3415 Magnetic stimulation to slow Alzheimer's To try to slow the negative progression of Alzheimer's disease Australians researchers have used a type of Transcranial Magnetic Stimulation called "Theta-burst" that has allowed to apply to four brain regions identified for this innovative treatment a shorter chain of high frequency stimuli in three minutes, comparing with other types of similar but less effective treatments that require forty-minute exposure of target areas where communication of nerve cells is hindered by aggregates of protein plaques. In practice better is the communication between cellular connections in the brain, and greater is the amount of information on which our memory will be able to reason. A seventy-eight years old participant to a test stated that she noticed significant improvements in the ability to remember. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Mar 16, 2017 n°: 3407 Under the Mauritius perhaps an ancient continent Many theories speculate that there was originally a primeval continent called Gondwana whose central part is now the Africa from which came off for the other continents with drift movements and now South African researchers went looking for zircons in Mauritius to prove that are granite fragments belonging to a super-continent including Madagascar, Seychelles and India that they came off once. Most critics have claimed that these zirconia crystals found at the beach may have been transported to Mauritius by the wind, vehicle tyres, shoes of tourists and even bird droppings showing some skepticism to the theory of this new super-continent that researchers have named "Mauritia" citing as proof that while the volcanic rocks on the island date back to about nine million years ago the zircons date from about three billion years ago. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Feb 04, 2017 n°: 3373 Dance rhythm for patients with Parkinson's That patients with advanced Parkinson's disease were able to accomplish in special conditions some movement had been found in a Dutch patient able to ride a bike and not to walk (usually without tremor or uncertainties) and now a Canadian study tries to investigate using brain scans on why some patients with this crippling disease that progressively removes the ability to move in coordination and balancing are able to dance quite smoothly almost surpassing suddenly every hindrance that limits their movement. The study still in its early stages would have shown how an hour of dance exercise increases alpha waves in the brain, and this also means an improvement in the balance of the body during rhythmic movements, but now it remains to be confirmed whether is a neuroprotective feature that remains over the time. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Jan 25, 2017 n°: 3364 Antimatter detected by a laser Using a laser to accurately measure the optical or spectroscopic properties of antimatter captured in some kind of trap containing antihydrogen researchers at CERN in Geneva would have discovered that hydrogen and antihydrogen have the same properties; in fact even the theory supports the hypothesis that in the violent explosion called Big Bang at the origin of our universe were formed equal amounts of matter and antimatter that then are annihilate into other particles and energy due to the process whereby the particles interacting disappear since the sum of their quantum numbers is zero. Concepts that are difficult to understand and to set an example on the topic the mathematician Paul Dirac (discoverer of the Positron in 1930 as antiparticle of the electron) said that like x² = 4 has two solutions x = 2 or x = -2 even in the universe there are two solutions, one positive and one negative. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Dec 23, 2016 n°: 3336 Mouth bacteria maybe responsible for headaches People who suffer from migraines among the various directions that should be followed according to the guidelines is to avoid processed foods for example containing nitrates (which added to the meat improves flavour and colour) and now researchers have found that in the mouth of individuals who often have headaches a significant presence of microbes that act on nitrates in order to convert them into nitric oxide in the blood stream, with effects on the caliber of blood vessels by improving circulation. The abundance of these bacteria in the mouth so it may also be responsible for a dilation of the blood vessels of the brain and the head causing migraine. Medicines containing nitrates are prescribed in cases of cardiovascular problems, but it was also noticed that these patients complaining then headaches as a side effect. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Oct 26, 2016 n°: 3287 Monkeys perceive whether someone is doing wrong In an experiment carried out by seeing a man a movie by an actor wearing a costume like King Kong while hiding an object in one of two boxes and then when the man went away moves the object to another place scientists studied the behavior of some orangutan while concerned the movie noting that these great apes identified the eye movement of the protagonists of the experiment and were able to figure out that the man would try to search the object in the wrong place. These capabilities typical of chimpanzees, bonobos and orangutans are very similar to those of human type to anticipate future actions and previous studies had already shown that monkeys can to realize the various thoughts simulated in experiments depending on what their partners see; so could be much smarter than usually think. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Oct 10, 2016 n°: 3272 A sheet of paper to make the stethoscope Using a simple trick that sometimes kids use to play in 1816 the French doctor René Laennec (Quimper 1781-1826 Kerlouanec) picked up a sheet of paper rolled up and supported it on the chest (in Greek "stethos") of a patient to hear (in Greek see "skopein") the heartbeat without having to support directly the ear on the chest of the woman, whereas at that time doctors usually don't ever touched patients and were limited to evaluate symptoms of diseases. The technique was described in an important "Treatise on mediated auscultation" of 1819; in fact this is the first medical anatomoclinic text that comparing the symptoms of diseases and the various lesions in organs to reach the diagnosis. Stethoscope initially was a kind of a wooden cylinder, then was disassembled for easy portability, afterwards it very evolved until to the use of electronic elements. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Sep 29, 2016 n°: 3263 The pigeons are able to distinguish written words Showing in an experiment on a screen a series of words in English consisting of four letters to the pigeons researchers would have found that the birds are able to distinguish the words with meaning by those who have not, at least from what emerges from a study carried out in collaboration between New Zealand and Germany who claims as pigeons are the first non-primate species with some ability to spell able to distinguish the orthographic. To check whether the four birds involved in the experiment simply just memorize the words of sense the researchers tried to add in the series displayed new words that the birds had never seen before finding the correct distinction in significant rate between words of sense by those meaningless perhaps identifying a couple of letters more characteristics of the true words. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Sep 20, 2016 n°: 3255 Mind - training * The author doesn't assume some kind of responsibility for the bad use of the articles councils (all rights are reserved) |
