life to teaching and research in Argentina

to analyze and improve the operation of water heaters and solar cookers has been working with for years, a group of Researchers at the Faculty of Engineering decided to begin the construction of a sundial. you understand how to produce energy delivery to collectors who have these teams and serve as a didactic element from which we can appreciate the movement of the sun, the seasons, the land position and tilt in its orbit. The engineer Paul Martin said the clock "may serve to give ideas and examples to students of Engineering, Humanities, Sciences and other academic units, and high school students and primary school who want to study the movements of the Earth and the Sun" . These are professionals
Research Group on Renewable Energy (Gider), which operates within the Department of Engineering Thermodynamics, who for some time began to give is the clock striking.

Matias Zaldarriaga

With less than 40 years, the physicist who graduated from Matias Zaldarriaga Exact-UBA has an outstanding scientific career. Ph.D. in physics at MIT 15 years ago living in the United States. He currently works in Princeton, where he sought to unravel the details of the Big Bang. Many point out as a future candidate for the Nobel. Visiting the College, as guest lecturer at the Physics Department, spoke to the Cable.


By Gabriel Stekolschik

- Your job is rather solitary?

- No, in general work with others. But I like when you can work in smaller groups. If you have to handle very large groups you end up making bureaucracy. Escribiendogrants (N.de R.: Order of subsidies), correcting how they wrote the papers. In short, doing things that are not as cute. I did not get to do escribirgrants physical, so I try to avoid that. So if I can stay in a tiny group, for which I need not raise money, I'm happier. Now I'm part of an experiment to try to fly a balloon from Antarctica to measure cosmic background radiation. It is a large group of people there and I do a minimal role. I tried to do some things, but I threw well, because it is much talk on the phone and turns into a job.

- not like work ...

- (Laughs) I like to think. It is much easier than you can think of an idea to invent something. But then when they do, it takes many years. And it's boring because you know that is something that will probably work, but in the middle is a lot of problems, collect the money, make grants, managing students and posdocs ... a job is done. I like doing things theoretical.

- Yours is basically "paper and pencil?

- Yes I sometimes work using data from a telescope. But often even use data. For example, I am interested in inventing what kind of measurement, what kind of telescope should be done. Then I do not. Or, if I interpret results from observations of someone who grabbed the data, reduced, removed something and I make a model to explain it. And sometimes I accounts that are not directly related to the outcome of an experiment, but with a future experiment that might do or not.

- What excites you most?

- Almost always there is a specific question about me is excited at a time and generally has to do with threads coming out of this group of four or five posdocs who work with me. In recent years, were things about Inflation Theory, the principle of the Big Bang, and the different observations can be made. Ways to make bills that had not been made and that sort of thing.

- and out of physics what you love?

- My family especially, because apart from work is more time as I am. With my daughters and my wife.

- Any hobby?

- I have. I like to run. I will run almost every day. Would run the entire marathon in Philadelphia, but eventually I will run only half. I have two daughters, little girls and I have to work so it's a matter of finding the time. When I have time, go out and run. Sometimes it's an hour, sometimes two.

- What do you think while running in Theory?

- (Smiles) Sure, yes. That is the best. Nobody bothers me. Because when I'm in the office, although I try not to have to work, come and ask me. And in my home I have a girl of 2 and 4, so it is impossible to do anything. I will end destroyed. I used to work at night, now reaching eight in the evening and do not want to do anything else. I can answer emails, things that do not require thinking, more bureaucratic. So when I run I can think of many things. There I have an hour a day, at least where I can do what I want.

- Did you meet their own limits to achieve a result?

- Things I can not solve? A lot.

- Do you consider the possibility of a Nobel?

- The odds of winning the Nobel I are very low. They may be higher than others, but they are super low. In other words, not think about it. Besides, the Nobel always give it to the old. There are exceptions, but often give it to people who are closer to ... no? (Laughs). Besides, most of the time they give for making any remark, and I did not comment.

- Making observations is part of the work that you do not like ...

- (Laughs) Yes, it's part of the work that I do not like. It's like teaching, I like to teach, but then when I have to prepare for class, there is always another thing I'm making beats. The same thing happens to work, to do experiments. At first I was amused, but they become very large and is, as I said, a lot of talk on the phone, to handle things in management.

- Are you consistent in your theoretical developments or like to nibble on different issues?

- more or less constant. I did four or five different themes but in which I was working many years. No I like to do very cortitos papers of different things all the time. But there comes a time when there are already many people working on the same thing and is more difficult than you can think of something to do. So there I start thinking about something else. Because when it gets crowded very difficult to compete, there are some who are very good. And sometimes I let things that are not filled because I was bored before. If I look back, I can see what he was doing four years ago and I was bored.

The math would predict the collapse of the courts


The news released in recent weeks about the danger of collapse of the Buenos Aires courts, like the courts pension houses in Marcelo T. de Alvear 1800, offer an incredible illustration of the nightmarish atmosphere recreated in his novels Franz Kafka.
With 35,000 new lawsuits per year and 400,000 cases awaiting resolution, the accumulated paper weight dangerously threatens to exceed the limit of 270 kg (sic *), according to the National Institute of Industrial Technology, should not transgress if it is to keep safe the integrity buildings.
But it's impossible to stop the feverish input files (not even won a three-week fair court authorized to request the courts), Mr. Ricardo Miró, mathematician "resident" of the judiciary, has just developed a system that would a warning for months or years before reaching this terminal crisis.
"You are four times when court buildings are collapsing under the weight of accumulated papers, has looked. I was working for the past five years on this issue and developed a series of algorithms that would anticipate this sort of" tsunami 'judicial. "

. Cosmos

science here and there, but ... Do you know what is its origin? When the universe began to see how a cluster of unexplained events?

all goes back to the 6th century BC in Greece. There, a group of scientists, among whom were Thales Empedocles and concluded that the universe was knowable and had an order and some regularities, that is, that nature worked around a set of rules, and not because of the "gods." This was the first major conflict between science and mysticism, and change from chaos to cosmos, or whatever it is, began to see the world as a set of events predictable, orderly and harmonious (cosmos), leaving the view of the unpredictable and unknown (chaos).

For you to understand better what I have said, here I leave a documentary Carl Sagan (1934-1996 New York), physicist and doctor in astronomy and astrophysics. This chapter corresponds to the television series Cosmos , issued in 1979.

Time magazine publishes a list of the 50 best inventions of 2010

month and a half left to finalize 2010, and with it comes the wave of lists of the best and the worst of the year. So Time magazine has not been left behind and has published a list of top 50 inventions this year.

Among them auto car drove Google , the iPad , the Chinese bus passes over vehicles, the bionic exoskeleton that allows a person in a wheelchair may take a few steps, the synthetic cell Craig Venter (a bacterium with significance for future vaccines), the laboratory-generated lungs (which would solve the problems caused by the transplants) and the glasses that let you draw or write following the movement of the eyes ( EyeWriter ).

Chinese Bus, and cell bionic exoskeleton Craig Venter / ABC

All these scientific and technological inventions are great improvements in research and development. The fact that a magazine Time published the relevance of these items, assist in the dissemination of the idea it all comes down to science.

Can you predict the future? The art of disseminating

Telepathy, prophecy, clairvoyance, precognition ... all these concepts hint at knowledge or discovery of the future. The possibility of "guessing" coming events has always been, and is, an enigma and a desire for the human race. Because of all this are the numerous historical documents, film libraries ( Back to the Future) and novels ( The Time Machine) that address this issue.

Today, thanks to advances in science, research on these phenomena are more effective. An example is the study by Daryl Bem , a psychologist at Cornell University (New York), which states the possible evidence that the future can be known and that the events occurred can not influence the behavior of human.

Bem has researched this issue for eight years, which has conducted nine experiments to 1,000 student volunteers.

In one of these experiments, showed his "guinea pigs" a list of words and asked to recall those that might. Later, students had to draw up a list of words that had memorized while a computer did the same at random. The experiment is surprising that the vast majority of words in the lists of volunteers matched those he had chosen the software.

Another experiment showed was that a computer screen which featured an image with two curtains, and were told they had to guess what was hidden erotic position. This study was repeated 36 times for each individual (the placement of the image was random) and consisted of 100 sessions, in which, 53% of students chose the correct shade (for the pure chance is expected to 50%) .

In the third study, the psychologist, spent the test in which a word is displayed first (usually "ugly" or "beautiful") and then a picture unpleasant or pleasant, with a view that the individual decides whether the photograph is "ugly" or "pretty" (in many cases are "flashed" with a word something that was otherwise so that the person will cost you to decide). Well, what he did was teach Bem first photo and then thought to ask what word would appear (again, was chosen by chance.)

In this experiment, Bem did observe evidence of psi (paranormal phenomena, by which the individual has the ability to acquire information through senses other than those already known - "sixth sense "-).

However, like everything related to parapsychology, this issue is very controversial. On the one hand, it is to publish an article with the results of this experiment in the journal Journal of Personality and Social Psychology , supported by the head of the editorial, Charles Judd. But on the other hand, this study has not convinced many scientists, Joachim Krueger and psychologist who has dismissed as "ridiculous."

If you are interested in this subject and I want to continue to report, there is a blog that posted a very interesting entry on precognition and its origins. It presents several interesting anecdotes. The blog is called cosmic Island and you can see the entry by clicking HERE.

SCIENCE WEEK 2010 IN ANDALUSIA


Today Tuesday, 16 are at the height of the Science Week. But are now a few intense days full of events.
Foundation on its web DISCOVER SCIENCE DIRECT coordinates all activities, among which are the 39 activities organized by the IFAPA of participation of 17 centers and the mobilization of 265 researchers and technicians.
A unique opportunity to access the scientific and technical knowledge generated each day.

White Initiation Dresses 2010

"The rigor in science journalism is increasing, is making its way into society, becoming a necessity." This is how Professor Manuel Lozano Leyva has inaugurated the series of lectures and activities that the cicCartuja has prepared for the Science Week 2010 (see previous post). It also cited the radio as the best means of scientific publication.

In his lecture titled Ten discoveries that changed the world view , which students have attended the School of Communication, presented the ten most important scientific discoveries (personally) of the universe. It has done so in a meaningful way: reducing scale from highest to lowest, ie the galaxies started and ended at zero and infinitesimal.

also worth noting here that Lozano is not only a great physicist, but also a great promoter (currently participating in the program's scientific gathering A life that are two days of in Montserrat Domínguez Cadena SER , and made several informative lectures and conferences like this, not to mention more curriculum-).

Ten discoveries that have reported are:

Milky

1 . Galaxies are the basic pillars of the universe and the stars.

here talks about the discoveries of Galileo , Kant and Hubble , among others. The latter who first discovered the telescope that bears his name.

2. Plate tectonics.

This theory equivalent to quantum mechanics because it explains everything (in this case the geological phenomena).

3. The origin of species.

The natural selection was discovered by Darwin and Wallace (independently) and was a breakthrough in the process of understanding the living (then there was the theory of Lamarck ).

4. The blood circulation.

This discovery made the medicine go from being an art to a science.

blood circulation

5. The Rosetta stone .

When Napoleon invaded Alexandria, he found this stone, which meant a breakthrough in the humanities, was the first language dictionary.

6. Microorganisms.

With the discovery of these, it was research in the field of disease (among other matters).

7. Genes (Discrete changes). With

Mendel and peas, we now understand the complex science of DNA.

Scheme Mendel's experiment with peas

8. Atoms.

According to Lozano, the atoms assume a probability distribution of presence.

9. The symmetry in the microcosm.

The discovery of symmetry at the microscopic scale, assumes that there is something rather than nothing.

10. From zero to infinitesimal.

Zero is nothing. The infinitesimal is the difference between nothing and a little (as little as you like, but non-zero).

Unfortunately I can not dwell on this interesting conference, but I can say goodbye the same way as it has Lozano Leyva: with a quote from Napoleon (1980).

According to a study, 360 patients, led by Ferran Morell, (head of the pulmonology of Hospital Universitario Vall d 'Hebron ), with the collaboration of researcher Ana Villar, this may be the cause of pulmonary fibrosis. Also investigated the phenomenon in Japan and the Netherlands.

This chronic respiratory disease (which can cause death) is characterized by scarring or thickening of the lungs (become rigid). Occurs because small pockets of air in the lungs become scarred; causing not enough oxygen reaches the blood.

The strange thing about this anomaly is that its causes are unknown, so it's a disease called "idiopathic."

usually occurs in people over 40 years and some of its symptoms are dry cough, chest pain, decreased tolerance to the sport, breathing difficulties and abnormal sounds within the body (like when removed the "velcro"). Patients with advanced disease often have a bluish (cyanosis) around the mouth or fingernails, and an abnormal enlargement of the fingertips.

Lung fibrosis

order not to leave the track and continue with the investigations, it has adopted an FIS predoctoral fellowship to this group of scientists.

On the other hand, medical solutions eradicate pulmonary fibrosis are still under study. However, the Guild of Naturists in Peru, based on bioenergy and alternative medicine have proposed natural medicines (herbs from Peru) as Namu, the Toxola, Jelly Toxola and as a regenerator, the Ananiper. They also use the magnet to increase exercise capacity, improving quality of life of patients.

X WEEK OF SCIENCE UNIVERSITY

From November 8 is celebrated throughout Spain, the X WEEK OF SCIENCE.
Week, is actually two because it lasts until day 21, is the time period in which the agencies involved to take science research to the street.
In that span, the researchers left our labs, our offices and our field trials and try to convey to society of science and technology we generate every day.
but also for public researchers is a matter of social justice: society, paying our payroll and fund our projects must receive at least a small part of that knowledge we produce.
In Spain, the Week is coordinated and driven by the FECYT and the Andalusia Foundation DISCOVER. Spain
In total 2177 activities have been organized and are involved 660 institutions, representing a 29'6% more than last year.
Those who believe in the saying that disclosure usually PEOPLE WITH MORE THAN ONE CULTURE, ARTS, INDUSTRIAL SCIENTIFIC OR MORE IS A FREE PEOPLE.

L'Oréal-Unesco Award for studies on the dark side of the universe

I like watching the stars on a dark night, but like any human being has the researcher of the Institute of Astronomy and Space Physics (IAFE), which tonight will receive the first prize (endowed $ 20,000) of the new national edition of L'Oréal-UNESCO Award For Women in Science, organized locally with the support of CONICET and distinguishes women who are dedicated to research career.

Tissera will be honored for his work trying to understand "the dark side of the art" using numerical models, and also receive mentions ($ 2000 each) Drs Susana Castro, National University of Mar del Plata, on the development project electroceramic materials, and Adriana Serquis, Balseiro Institute, for his research on materials for clean energy. All of them are researchers from CONICET.

Tissera and his colleagues try to explain the evolution of the universe from what could be considered a blink of an eye (on the cosmological scale) after the Big Bang.

Goodbye!

Science comes to all fields and possible investigation. So much so, that a Scientists at the School of Medicine, Johns Hopkins University (USA) has managed to find a way to eliminate the bad memories of the brain, reflecting localized proteins in the nervous system.

Although there has not been seen in humans, this study shows positive results in mice. According to neuroscientist Richard L. Hugair, animals were given an electric shock accompanied by a noise. Then after a few minutes, when the mice heard the noise again, stood still, trembling with fear. This reaction leads to increasing the activity of certain nerve cells associated with a protein AMPARs calls.

Hence, the researchers drew the conclusion that eliminating these proteins (which caused the fear of memory), would eliminate the bad experience.

However, these studies are aimed at improving the lives of people suffering post-traumatic stress or other illness that prevents them from leading a normal life after suffering a nasty episode (wars, terrorist attacks, kidnappings ...) .

BACKGROUND

is not the first time that human beings try to create clear memory mechanisms. A year ago, surprised us the zip, which is an inhibitor of an enzyme brain associated with memory (PKM zeta). In experiments on mice, we observed that a dose of ZIP was able to delete specific memories have enabled the animal at the time (without distinction). However, it was concluded that this molecule attacked the declarative memory (spatial memory, accessible information. Remember facts, events, associations and conscious situations) and not the implicit (emotional memory, learning situations that occur fear. Procedural memory, memory skills).

Another important study is to Merel Kindt and colleagues at the Department of Clinical Bio Psychology at the University of Manchester on propranolol, a drug used to treat hypertension, can block the memories. But it's better than pincheís HERE and you see the news that World posted about this.
