not only to health: quitting smoking is good mood


Not only is it healthy for the body: to quit smoking improves the well-being or mood. A support is a study published in the journal Nicotine & Tobacco Research by researchers at Brown University and the University of Southern California led by Christopher Kahler.

The study shows that, regardless of who has the habit of smoking tends to light a cigarette every time he has to 'download' anxiety and nervousness, the beneficial effects for mood would come from our very own conduct contrary, that is, interrupting the consumption of the "blondes".

The researchers monitored the symptoms of depression in 236 people trying to quit with the vice of cigarettes, They found that the moment of greatest happiness is reached when they could just draw a line of cigarettes.

"The hypothesis is that some people smoke because smoking has antidepressant properties - said Kahler -. What is surprising is that, when you measure the mood of smokers, is no improvement in the mood though managed to stop only for a short period. "

Asking For Money Birthday Poems

Research is art


Manuela Pellegrini, a young researcher at Tor Vergata and AIRC with a past in the States, gave an interesting speech a few days ago at the Maxxi Rome. Followed and appreciated by the students, the discourse of the research was focused on the parallels between art and research. The doctor holds a Airc My First Grant, awarded by the association to new talents.

D: The researcher: more than a job or a vocation?
A: There are several personal reasons that can lead to the occupation of the researcher (curiosity, attitudes and interests, humanitarian, randomness), but ultimately for all of us becomes a passion and a mission.

Q: What is the motivation that led her to choose this life? If you could go back would take the same career?
A: In two words I made a choice that prefers the verb "be" rather than "having". As I mentioned before, I started this career because I wanted to study animal behavior in nature, only later I discovered the incredible charm of molecular biology and the possibility that you have to use it for a collective good. If in the past I had many doubts about the career undertaken, as the difficulties are overcome are happy not to have abandoned the world of research, also made the discoveries, personal fulfillment and the people I met during these years to pay off far all sacrifices.

Q: What are the deeper differences that you, as a woman first and then as a researcher, found between Italy and America? And why is back in Italy?
A: As a woman of science I never experienced discrimination during his time at NIH in the U.S. and I always had the impression of being listened to contribute different perspectives to the research lab where I worked. In Italy, unfortunately, is another story, still widespread in the academic world is a certain "machismo" and also the organization of work is not such as to allow the reconciliation, for example, with motherhood. A problem of organization and efficiency, there is also doing a lot of research often for lack of communication and sharing of resources among various departments. One aspect that I personally was very mature when I worked abroad was a chance to meet on an equal footing with the heads of department and laboratory experience that definitely had a lot greater than mine, I was not in any way held against the office. Unfortunately this happens very rarely in Italian universities. I came back because I grew up with the myth of Odysseus described in the Odyssey. It should start to learn and then use this knowledge to understand themselves (their potential and limitations) and to be confident of their work, but it is equally important return, especially for us Italians we feel and know the value of nostalgia (nostos algos-return-algos) to a country that currently has "cure" but with its ancient history and culture has made us unique in the world . In the end I went with the hope of helping to cure.

Q: What, in your opinion, key areas of research today?
A: Make a distinction between a search field and the other is not possible. We can not believe, for example, that research on HIV may be more or less important in cancer research or vice versa. I believe that all basic research should be supported.

Q: What about the meeting which was held at Maxxi of Rome. It was the first time he spoke to an audience of young people? More or less exciting than the present study to a group of experts?
A: I did a few lessons to university students in the past, but it was the first time that I spoke with high school kids. It was not a technical intervention but I talked about my experience of growth and the work of the researcher and I are very excited in trying to convey the passion and the emotions I feel for my work. In this respect was therefore a unique experience that will stay in my best memories.

D: Research and art. Why create this combination? What does "the researcher is very similar to an artist?
A: A researcher as an artist must be free to express themselves, they must both be able to see things from different points of view, must also use past knowledge to explore new dimensions, and finally they both work for the community, the researcher for the welfare body, the artist for the spiritual.

Q: Let's talk about research ethics, bioethics and morality. There should be limits? If so, how and when should be imposed? And by whom?
A: I try to do my job, having always before the secular version of the triad "faith, hope and charity." I do not think that the end justifies the means must always act with conscience, justice and compassion. At least that I have always appreciated the people who have been our guide.

Q: Where should we start to establish a solid foundation for the future of search? How to help improve the quality and finally the coveted "Header"?
A: First you need to convince those who have the ability to support research that is synonymous with future research and the Italians more than ever in this era need to see a future. Have more investment in research will also create more jobs and encourage merit the return of researchers who have specialized abroad. I believe these are the conditions for the establishment of a positive feedback that will surely lead to improved research and extension of our knowledge.

discovered bacterium that eats arsenic


It was discovered a bacterium "alien" that feeds on arsenic. Not in the sense that alien from outer space, but its metabolism is not based on oxygen, hydrogen, nitrogen, phosphorus, sulfur and carbon as all other living beings on this planet, but on something that is poisonous to life in his complex. The bacterium is the strain GFAJ-1 family Halomonadaceae class Gamma Proteobacteria that live at the bottom of Mono Lake, a lake in California on the border of Yosemite Park, known for its extremely alkaline water (pH 10) containing high amounts of arsenic and salts that are deposited to form beautiful travertine concretions and locally are called tuffs, although geologically are not.

The bacterium has been modified in a laboratory of the Institute of astrobiology at Arizona State University ordered by Felisa Wolfe-Simon, thanks to research funded by NASA and published Thursday in Science. Now the life of the bacterium is completely up to a poison such as arsenic. The existence of such an organism is the proof that life can exist in forms very different from those we know, a figure which can not fail to take into account all space programs involved in the search for living beings on other planets. "The great news is that arsenic is utililzzato as a building block for an organization," said Professor Ariel Anbar, co-author of the study. Researchers have grown in laboratory bacteria found in the mud of Mono Lake with high levels of arsenic. A little 'time, biologists have increased the amount of arsenic in the culture medium for bacteria, microorganisms make up completely dependent on that element. That bacteria have managed to survive was a surprise to the researchers. The bacteria strain GFAJ-1 are now the only form of life known so far in which a toxic substance such as arsenic replaces the phosphate, which is essential to the vital functions of all known life forms. Phosphate is in fact the basic molecules of all cells.

The superbug New Delhi shakes the world:


E 'alert in Italy for the superbug "New Delhi", resistant to almost all antibiotics known today: two cases of infection were in fact registered in our country. The news was the director of the infectious diseases department of the Higher Institute of Health (ISS), Giovanni Rezza, at the presentation of the Campaign of antibiotics, defend your defense. Use with caution. " The superbug, a native of India, has also appeared in Europe (UK, France, Sweden, The Netherlands) and the United States. E 'is resistant to most antibiotics and no new antibiotics in development is minimally effective against this organism, also known as NDM-1.

''The appearance of the superbug in Britain - said Rezza - is also partly due to a phenomenon of 'outsourcing' of surgery, for which interventions are made in India, for example, very expensive cosmetic surgery in Britain ' '. In Italy, she made known to the expert,''there has been only a couple of cases of infection in people returning from trips abroad, and there is still a real spread of the superbug, which can cause pneumonia, septicemia and infection.'' There is, however, concluded Rezza,''a state of alert and the phenomenon is constantly monitored.''

Despite the attention to this superbug must remain high, Rezza says worried by the fact that we are lowering our guard against other resistant organisms, "There are other bacteria that are resistant to the same classes of antibiotics that NDM-1 circulate in our country, now this is a serious problem especially for gram-negative bacteria, because these infections circulating in departments such as intensive care, where patients are already weakened by other serious diseases. "

The means to defend itself against these superbugs are very few: "The last bastion is the colistin (with very strong side effects, ed) - said the professor - but it does not work in cases where the problem becomes serious. There is a lack of research and development in this field, obviously the economic performance is poor compared to the investment needed, so the discovery of new drugs are lagging behind. "

With the name of NDM-1 defines a gene that can "jump" between different bacteria, giving an important resistance to carbapenems also, class of antibiotic considered the last bulwark against the microorganisms more dangerous. Throughout the Old World have been reported in 13 countries, said Dominique Monnet European Centre of Disease Prevention and Control (ECDC). "Until now - said the researcher - were reported 77 cases of NDM-1 infection in Europe -. Were affected 13 countries, including France, Italy, Germany and Spain, and there have been seven deaths. Two-thirds of cases occurred in Britain and most are associated with medical care or travel in the Indian subcontinent, although a small amount derived from an outbreak developed in the Balkans. "

Airc ineffective antibiotics, tumors frighten young


The Cancer is a disease that is still very scared young people. But beyond the terror the boys also have many interesting, want to understand how it forms, how we get sick, and how to defeat. And how you can join the battle. These are the main questions that students in high schools and technical institutes in Milan has turned to experts in the day for cancer research organized by AIRC in Milan, at the IFOM-IEO Campus.

Questions that came from young people not yet eighteen, but already had the depth and maturity of adults, someone asked the causes of the disease, its inheritance, how do you heal. Someone else wanted to deepen the work of the investigator, how they propose ideas for the tests and how to obtain funding. Others, finally, maybe they were already screened in a future scientist asked the experts if some ideas have already been proven, if a certain route of care had already been attempted.

So afraid of cancer but also a great desire to understand and one day to see them defeated. Many have asked "how many people are actually cured of a tumor," and if the healing can really say definitively. "Absolutely - said Marco Foiani, IFOM researcher - and one of the goals today is chronic disease. For example, in diabetes before they died, but now you control the disease with insulin. This is achieved with the tumor, but the long-term goal is certainly defeat the disease altogether. "

Some students asked if there is a link between psyche and cancer ("difficult to say, they say the experts), one in particular has proposed, instead of killing cancer cells, to try to make them return to normal. And in fact is what has been done in the past with a certain type of leukemia, said a scientist, although today the most promising approach is to target the whole environment that is around the tumor, to cut 'food and kill him. Some guy, finally, perhaps imagining a day of work in science, asks whether Italians are really the brains on the run, and how do you get them back in Italy. "With the excellence of our schools - said Tiziana Bonaldi secure the European Institute of Oncology, she returned to Italy after several experiences abroad -. And making Italy a place where both Italians abroad that foreigners want to come and do research. We have to learn to bet on youth - he concluded - because it's a bet that many times then pay.

The war on cancer is a real game of chess with each move by cancer researchers responded with a new strategy to 'escape attention; and that scientists react with a counter-move faster and faster. Today checkmate cancer seems a little 'closer: the winning move would be to affect the environment in which the tumor develops, taking away everything that used to survive. And to carry out research in this field is Paolo Ghia, San Raffaele University in Milan: his is one of five projects funded by the Italian Association for Cancer Research (AIRC), with the funds of 5 per mille . "The idea of \u200b\u200bhitting the micro-environment - said the expert - was created for cancers of the blood, but now is the new frontier for all types of cancers, including solid ones. It seemed an idea of \u200b\u200bthe niche, but now it no longer is. "

Some treatments, such as those that block the blood vessels that nourish the tumor, affecting only one aspect of the disease, the approach of the micro-environment, however, is more cooperative: they bring into the field several weapons, and once you hit the tumor from all sides. "Our goal - continued Ghia - is to try to clarify the components that help the tumor grow and then stop them. This, unfortunately, just because even a single tumor cell, hidden and protected from its environment, because the disease returns "

A researcher is very similar to an artist, despite the platitudes they want science and art as two separate worlds. He said the oncologist Umberto Veronesi during one of the meetings between researchers and the public organized by AIRC during the day for cancer research, which was held in Rome at the headquarters of the museum Maxx. "Science and art have much in common - the doctor said - in both camps are imagination and creativity. In addition, many arts, like music, are actually based on mathematics and geometry. "

In all the meetings this year, cancer experts are guided by an artist, and in the case of Rome this was the master Michelangelo Pistoletto, who was also convinced of the possible coexistence of both worlds: "Art from the person may arrive at the company - said Pistoletto - and I am convinced that it is time to do as in the Renaissance, when art and science have come together to heal the ills of society. " The meeting was attended by approximately 150 high school students, special care during the intervention of Manuel Pellegrini, a young researcher at the University of Rome Tor Vergata just returned from the USA who has tried to portray the beauty of his work and sacrifices, " In Italy there are difficulties at several levels - he said - especially because the funding is not sufficient and there are no jobs for young researchers who have a life that ensures the progress of projects. However it is worth engaging, especially to give hope to patients and their families. "

"tanning centers are veritable factories of cancer." It is convinced Professor Pier Luigi Lollini, who introduced the debate organized by AIRC in Bologna for the day to cancer research. Lollini insisted on prevention, "which would allow, and this is the goal of eliminating 50% of the tumors," pointing out that among the factors are in fact carcinogenic ultraviolet rays. These, as well as from the sun, are irradiated by its own lamps for tanning. Responsible for one third of cancers, said Lollini, however, is the smoke. "In Italy there were 80 000 deaths this year from causes related to it, half of them from cancer." To In comparison, adding the deaths' accidental, homicide, suicide or an accident, you get to about 30 000 deaths, said the professor at the University of Bologna. Smaller, however, the pollution factor, responsible for only 1% of the diseases.

"It is true that living in cities increases the risk," the professor. Alcohol causes cancer and 4%, 3% obesity, low physical activity levels of 2%. The new frontiers of research, in particular to two projects carried out by the association with the funds of five per thousand, was devoted to the discussion. "The first news - explained Professor Stefano Pileri, he University of Bologna - Is the development of new targeted therapies. Ie move from rigid protocols, applied to all patients, to study more and more personalized care. "

Male-flops: they are women to be programmed for longevity


Males for recycling, self-sufficient women. Other than the weaker sex, the female body is designed to better withstand shocks "organic" life, according to a study by the University of Newcastle, UK.

Tom Kirkwood's hypothesis, researchers of the British, published in American Scientist, is that the body of the woman is able to run a mobile phone service more efficient than the male.

That is the reason why, at all latitudes, the life expectancy of women exceeds that of the other half of the sky: in Italy women beat the men by far, one with an average age of 84 years vs 78 .

"Our DNA is programmed to optimize resources for reproduction," says Kirkwood. The main task of the genetic blueprint that is female and "the health of the machine-woman is very important for the development of the fetus first and then the child. Why, then, males are more fragile? "The role of man - sentence the expert - is less dependent on his health."

Pain Around The Belly Button At 34 Weeks Pregnabt

carbonated beverages trigger the genes responsible for pain, which is why 'pinch' as spicy mustard


orange nose and aerated in the same trigger painful sensations in the mouth that are caused by chili, mustard and ginger:
to a new study conducted by a team of researchers at the University of Southern California (USA) led by neurobiologist Emily Liman and published in the Journal of Neuroscience that would be the carbon - that is, the process-based carbon dioxide effervescence responsible for these drinks - to trigger the sensation of pain sensors in the nasal cavity and throat.

"The carbonation evokes two distinct feelings: it makes things acidic and causes seem to burn - says Liman -. We have all experienced the feeling Intense tingling when
fizzy drinks go down too fast by the throat. The cells that respond to carbon dioxide are the same as that detect the spicy hot mustard. "These cells express the TRPA1 gene and serve as sensors of pain in general.

The gene, however, provides only one aspect of sensory experience of carbonation, that of feeling like the pain, the researchers said, another study had shown previously that to convey the feeling of acidity are some cells on the tongue.

Xara Photo & Graphic Designer



Xara Photo & Graphic Designer is a well known photo-editing software from MAGIX AG, which goes right in line with quality multimedia programs that have published for several years. Among the programs and Othe 'one of the best photo editing software. Unfortunately, it is unable to equal to the expectations placed on it from other MAGIX offers. You're still going to get a good photo editing program, if you want to buy. This program is free and you can easily buy from www.xara.com. but is far from the strongest member of MAGIX product line. The interface in the latest version which is version 6 has been completely redone to improve workflow and remove the unpleasant task of having to search around for something you need.

characteristcs one of the most important of it is the ease of use:

generally for a complex photo-editing software, Xara Photo & Graphic Designer is very easy to use. It is not difficult to find instruments and effects you need to get the job done. Your will find that their approach vector is better, more powerful and easy to use. MAGIX took the liberty of combine several applications into one, which makes things easier on your end in terms of time and money you would spend learning and acquisition of other programs. This approach also gives the program a little 'Extra' Staying Power. you can see the value of the latest version of http://www.xara.com/us/products/designer/whatsnew/. If you choose Xara Photo and Graphic Designer, you're not going to have to collect any other photo editing software.

next feature: Importing:

Xara Photo & Graphic Designer is full of import options. According to our estimates, this program has supported the possibility of importing more than 40 different video and image file formats. We had a hard time finding another program in this category that can beat the flexibility of this program gives its users in this area. Having a lot of import options is important because it gives users the ability to incorporate design elements from all ends of the spectrum. It 'good to know that the editing software you choose is not going to limit creatively.

Editor:

You are not going to see a lot of editing features in Photo & Graphic Designer Xara other photo editing software. Normally, this would fall to a program, but here just useful. The unique features make up for the lack of common characteristics. If there were no unique features, editing features in this program would be pretty sparse and weak. Fortunately, MAGIX has decided to throw in a couple of things we've never seen before. If they had their program would not be as good as it is. Editing is now much easier in Photo & Graphic Designer Xara than ever. We liked the fact that there are additional editing functions pack that may or may not have been of no use to you. Instead, they decided to improve how easy it is to use stellar options which are already there.

functions sharing Xara in Photo & Graphic Designer includes:


* * E-mail Print
Projects * Projects * Digital
Export in online photo services
* PDA, Cell Phones

We would have liked to have seen the addition of an option to share our photos as an online gallery or post them on our Facebook and other social media medians, but the current feature set is more than enough.

output capability:
Photo & Graphic Designer
Xara is one of the few editing programs that have as many options as does export import feature. We found that the lists of import and export do not match perfectly, but the amount of export options is here perhaps more than anything else you would find in the industry.

Organizer:

to organize the file in Xara Photo & Graphic Designer 6, you can use a file browser, store your images on CD, assign ratings to your photos and view EXIF \u200b\u200binformation. When you are finished organizing your images, you will be able to search for them using the advanced image search. The only option Xara Photo & Graphic Designer is not offered in this category was the ability to create albums. Although this function may not be important for some, his absence would certainly be a negative for many others. . It needs to be added to the program in the future.

Help / Support:

Users can get in touch with Xara by phone or email. Before contacting them through these channels, however, Xara want to look at the manual, the FAQ, knowledge base, tutorials and forums of the first user. All these options are put together to make it impossible for you do not find the answer you were looking for.

Summary:

Xara Photo & Graphic Designer 6 is sound editing software that quickly wiggle its way into your graces. We thought there were a few things Xara could do to improve the program, but these changes are sure to come with the next update. Many of our previous concerns have been addressed and fixed already with the '6 'version. Until then, you're going to get a great photo editor if this program is the one you choose.

Created in the laboratory a new super artificial skin: is more sensitive than human


E 'was built in the laboratory and was now called "e-skin", the artificial skin a thousand times more sensitive than human. E 'was obtained thanks to nanotechnology by two independent research groups that have used different types of materials. Either way, described in the journal Nature Materials, has led to a "skin" that could be used to give sensitivity to future robots and feel similar to humans, to coat implants of new generation or more for new touch screen technology.

The new material more sensitive to human skin is composed of new-generation pressure sensors, placed on a layer formed by a very flexible polymer. The two groups that have worked this goal are both in California: the University of Stanford Zhenan Bao and co-ordinated by the University of California, Berkeley led by Ali Javey.

"Our sensors are more sensitive than human skin," says Zhenan Bao. "A gentle touch of the skin - adds - corresponds to a pressure of about 0.1 grams applied to a square millimeter of surface area. Our sensors are 1,000 times more sensitive, they feel pressure to fly a very light (20 milligrams) that posing on them. "

is not the first time, of course, that you work with artificial skin, many research groups worldwide are working on it and it's a race to produce 'skin' most sensitive and as flexible as possible because it assumes the appearance and capabilities of the human. In robotics for many years working with sensors that mimic human senses, sight and hearing about a lot of progress has been made to smell and touch the work is more complex.

The challenge of developing a technology as sensitive as human skin has been taken successfully by Bao and Javey, who created, with different methods and technologies, ultra-sensitive touch sensors, available on flexible surfaces and therefore well suited to the complex human reality ( eg implants). Both groups have built ultra-sensitive sensors and high reactivity to touch, ie rapid response capacity in a few milliseconds. This is a huge leap forward compared to previous attempts.

But ideas do not end there and there is still room for much research to make artificial skin more and more human-like in terms of sensitivity, for example, says John Boland, Trinity College Dublin in the same journal commenting on the two research could enrich the artificial skin sensors for temperature and humidity, or even create sensors that simulate the feeling of hair follicles and scalp.

spaces applications are enormous, Boland said, not only the prosthesis or robotic, "The artificial skin could be used to develop precision instruments that enhanced in human skill and dexterity, tools that could be used for example in minimally invasive surgery. Other potential applications include touch screen technology. Whatever the application - the expert concludes - these sensors are low cost and ultra-sensitive, designed on flexible substrates and in this sense the work of Bao and Javey represent a milestone in the development of ultra-sensitive touch technology. "
