Diets for Maintaining The Famous Figure in Christmas

During the holidays, Christmas and New Year, the intake of foods with high caloric content is very common in people. This situation is disturbing, because it increases their chances of gaining weight and losing the line, affecting not only the physical appearance, if not the health information portal Health.com.

The British site of the magazine and Web MarieClaire.co.uk specializing in health issues, YourTotalHealt.iVillage.com published a series of tips released by celebrities such as Carmen Electra, Gwyneth Paltrow and Jennifer Aniston, who claim not to lose “line” during the last month of the year.

The American actress, Gwyneth Paltrow, who won an award “Oscar” for the film “Shakespeare in Love” in the year 1998, admitted carrying out the so-called macrobiotic diet. This diet was created by the Japanese George Oshawa, Japan philosopher who bases his knowledge on the balance between man and nature. Continue Reading »

The 10 Developments That are Expected for 2010

With the potential discovery of dark matter, the publication of the genome of Neanderthals and the early announcement of the creation of artificial life is every indication that 2010 will be a great year for science.

Electric cars. If this is the future of green motoring, count on us. Evar electric hybrid developed in Canada by Future Vehicle Technologies, can accelerate to 100 kilometers per hour in about 5 seconds. The EVAR is one of the contenders of the Automotive X-Prize competition, which begins in May. At stake are 10 million cars that will go to obtain the best performances in overcoming the electrical energy equivalent to 42.5 miles per gallon of fuel. Over 40 teams from around the world will participate in the competition, culminating in a stage race that will cross the United States. X-Prize Foundation, which organizes the competition, requires that the vehicle must be manufactured in series, a quantity of 10,000 units per year by 2014.

Brother Neanderthal. Do we have a little Neanderthal in us? With the imminent publicadión of the genome sequence of Homo neanderthalis, that question will remain unanswered. So far, nobody has found evidence of interbreeding between species. The genome of 3 billion nucleotides in the Neanderthal is our best chance to find out. For starters, any sign of inbreeding would lead us to rethink our place among our ancestors. Researchers working on this project have already discovered some details of the nature of this hominid: a few individuals were white-skinned redheads, they must have spoken complex language.

But a complex genome means that our closest ancestors can be analyzed in greater detail. With the Neanderthal genome, geneticists will have a branch that split from the branch of Homo sapiens made only 500,000 years. And that twig could explain changes that made humans human.

Dark matter. In the 27 miles of tunnels running under Geneva, the Large Hadron Collider will begin colliding protons to high energy by 2010. This seeks to confirm the existence of a particle called the Higgs boson. However, it is unlikely to happen in 2010 instead, another particle might become news this year: the neutralino.

Nobody has seen, but their existence has been postulated by the theory of supersymmetry, which allows to solve several problems facing the standard model of physics, it doubles its number of elementary particles. The neutralino is the perfect candidate to explain dark matter. It is easier to find that the Higgs boson, and their presence could solve two problems: supersymmetry and respond to confirm what makes up the missing mass of the universe, according to the standard model.

Waiting for ET. April 2010 marked the 50th anniversary of Project Ozma, the first to look for signs of intelligent life beyond Earth, and those involved in the quest for extraterrestrial life (or SETI, English) raise their glasses. Not only that project inspired so many people today to continue the search, but has allowed the investigation of extraterrestrial life would lead to the science of astrobiology. Today researchers are seeking other forms of extraterrestrial communication, such as short pulses of light. Frank Drake, a pioneer of Ozma, plans to start in 2010 with a more accurate way to search, which employs seven unprecedented light detectors simultaneously. This will distinguish extremely weak signals, and is virtually immune to false alarms that abounded in previous experiments.

Create life. Synthia Wait: that’s what enthusiasts have been making synthetic life since the genomics pioneer Craig Venter promised to create a bacterium with a laboratory-made genome. The date of delivery proposed by Venter is 2010. Synthia is the popular name proposed for species with lab-created genetic instructions. When in January 2008, Venter announced that he had created a synthetic genome of a bacterium found, the M. genitalium, Synthia’s birth seemed imminent. But the goal has not been as easy to reach. Venter has had to battle against various problems, including enzymes that destroy DNA.

Other researchers are working on the components of a fully synthetic cell. George Church, Harvard announced that it created a ribosome (the cell that produces proteins) autoensamblante. Church hopes that next step-getting-autorepliquen these ribosomes is given in 2010.

I heard teeth that help r. It is said that Beethoven overcame deafness to attach a rod to his piano and squeeze between your teeth, allowing the musical vibrations that travel through your jawbone to the inner ear. The next year a device that mimics what the hearing will return to one of the most common forms of deafness.

The so-called single-ear deafness prevents people can detect the exact source of the sound. The firm Sonitus Medical, California, has created a small device placed in the teeth: picks up sounds through a small microphone placed in the deaf ear and turns it into vibrations. These travel through the teeth and jaw healthy ear where the brain provide stereo sound. For the Cleveland Clinic, will be the main medical innovation 2010.

Farewell to the spacecraft. Not long ago, space was the Wild West, won by brave men who rose to the skies in fierce rocket. That era ended with the space shuttle: as elegant as a freight train and futuristic as a washing machine, their goal was to go to space routine.

It did not work so well. Going into space will always be expensive and risky, which became clear after two tragedies featuring ferries. Still, took hundreds of people into space and allowed the construction of the ISS; this year, are scheduled the last shuttle flights. After September the museum will be material from which we remember-while you decide what the next phase of the U.S. space program, which once aspired to do something democratically spaceflight mundane.

Microvalve Development for Glaucoma Treatment

According to a report distributed by the University of Entre Rios, scientific studies that house managed to develop a smart microvalve for relief and treatment of high intraocular pressure in glaucoma patients. Currently, researchers working on the development of a prototype called the valve (i-mvalva), to test on animals.

“We are at a stage prior to preclinical testing, developing the prototype for deployment in animals,” said Dr. Fabio Ariel Guarnieri engineering, director of research and research group Conicet.

Glaucoma is a degenerative condition that damages the optic nerve fibers that affects between 1 and 2% of adults. One of the main factors which cause this disease is high intraocular pressure, which causes progressive damage to the optic nerve that can lead to blindness.

The first to treat glaucoma valves were developed in 1969 and connected the anterior chamber through the sclera with a silicone conduit. Currently, to avoid an excessive drain valves are marketed such as Ahmed, who have elastic mechanisms that reduce its hydraulic resistance with increased intraocular pressure. Continue Reading »

Loneliness is Sometimes Can Be A Theraphy

A group of scientists formed by specialists from several U.S. universities like Harvard and the University of Chicago, concluded that loneliness is contagious within social groups. Reflect this conclusion in a scientific research article published in academic psychology journal The Journal of Personality and Social Psychology.

“We found a remarkable pattern of contagion that causes people, when they feel alone, are marginalized from social networks,” says Dr. John Cacioppo, who led the study at the University of Chicago, reports the British broadcaster BBC its Spanish-language news portal.

The way that becomes contagious loneliness is related to the breakdown of social and emotional ties between people. If an individual feels isolated only start, a fact that deprives their friends and relatives of his presence. Although that person is not really alone, just feels that way to be truly isolated.

Top Medical Breakthroughs of The Past 200 Years

The last 200 years have served to specialists and doctors from around the world to work on new discoveries. They have helped save more lives and more effectively treat various kinds of illnesses, indicates MundoExtra.com portal.

A survey by the “British Medical Journal” (British Medical Journal in English) revealed a list of the most important medical discoveries of the last two centuries. The selection was made through an electronic vote, which took into account the relevance and impact in science, their achievements.

Some of the highlights were the discovery of DNA structure as well as antibiotics and the pill. Meet the most important according to a Spanish newspaper 20minutos.es list.

Anesthesia. It was designed with the intention of reducing pain sensation. This medical procedure was described by locking the “British Medical Journal” as “a symbol of humanity and civilization. It was discovered in 1842 when Dr. Crawford Williamson ether used during a surgical procedure. Over the years it has evolved and changed components.

Antibiotic. It is a chemical produced by a living being and is used to treat an infection caused by several types of germs. The term was first used in 1942.

Chlorpromazine: Neuroleptic drug; was discovered by Frenchman Paul Charpentier in 1950. It is commonly used as a tranquilizer and is prescribed in psychiatric medicine. Helps people with schizophrenia and those who have been diagnosed with Huntington.

Tissue culture. It is a technique based on placing a piece of plant in a container helped with artificial nutrient solutions and plant hormones to propagate in a sterile environment. This technique is owed the existence of several vaccines, such as preventing mumps, rubella, smallpox.

Discovery of DNA structure. James Watson and Francis Crick proposed in 1953 the double helix model of DNA to represent three-dimensional structure of the polymer. Since then, the human genome has allowed great progress in the study of hereditary diseases.

Contraceptive pill. Mexican scientist Luis Ernesto Miramontes was the inventor of this method of contraception in the year 1960. Hormone-based works and aims to alter the menstrual cycle to prevent ovulation and therefore conception.

X-ray. They were discovered by William Crookes in the nineteenth century. Telegraph.co.uk The English newspaper named him as the best invention of the modern era.

Germ theory. It proposes that microorganisms are the cause of many diseases. Their study in modern medicine is essential to develop antibiotics. Its discovery in the early twentieth century reduced the death rate of 30 to 4 percent.

Vaccines. Edward Jenner developed the first in the year 1796, to treat smallpox. They are based on a preparation of antigens that, once inside the body, causing the production of antibodies to defend the system of pathogenic microorganisms. Continue Reading »
