SOLAR OBSERVATORY SDO «Open" NEW OPTICAL PHENOMENON ON EARTH

Solar Observatory SDO «opened a new optical phenomenon in the world Specialists in atmospheric optics Les Cowley (Les Cowley) and Robert Grinler (Robert Greenler) decoded data obtained at the start fromour solar observatory NASA's Solar Dynamics Observatory (SDO).

SDO was launched on February 11 last year, and two months later the researchers presented its instruments made test shots of the sun. Not related to the physics luminaries useful information unit, as it turns out, he began to collect much earlier.

Spectators gathered near the launch site at Cape Canaveral, was lucky to remove the video not only the successful launch of the carrier rocket Atlas V, which put SDO into space, but also a relatively rare atmospheric phenomenon - a mock sun (sun dog). The latter is considered a type of halo, usually seen on the left and right of the morning sun and is formed by the refraction of light in cirrus clouds - in flat hexagonal ice crystals floating in the atmosphere. The most interesting thing, however, happened a few seconds after liftoff when the rocket rose into the sky: the shock waves have broken the location of crystals and sun dog disappeared.

The destruction of the rainbow Parghelia (see the right side of the Atlas V) and the formation of a vertical white band (illustrations George C. Privon, NASA).

Destruction Parghelia researchers explained quickly, but a different effect on modeling the impact of shock waves, they had to work hard. Next to Atlas V appeared bright white vertical band that accompanied the rocket, - says Mr. Cowley. - Nothing of the sort we have not seen before.

The desired result is given a non-trivial model in which the axis of the crystals is rejected by 8-12 degrees from vertical, and they precess like a top. Calculations showed that the observed band - a unique rocket look halo - was only part of a much larger oval that would appear in the sky, in the ideal case.

NASA | Solar Dynamics Observatory: 1st Year Anniversary Collection

Описание:

April 21, 2011 marks the one-year anniversary of the Solar Dynamics Observatory (SDO) First Light press conference, where NASA revealed the first images taken by the spacecraft.

In the last year, the sun has gone from its quietest period in years to the activity marking the beginning of solar cycle 24. SDO has captured every moment with a level of detail never-before possible. The mission has returned unprecedented images of solar flares, eruptions of prominences, and the early stages of coronal mass ejections (CMEs). In this video are some of the most beautiful, interesting, and mesmerizing events seen by SDO during its first year.


In the order they appear in the video the events are:

1. Prominence Eruption from AIA in 304 Angstroms on March 30, 2010

2. Cusp Flow from AIA in 171 Angstroms on February 14, 2011

3. Prominence Eruption from AIA in 304 Angstroms on February 25, 2011

4. Cusp Flow from AIA in 304 Angstroms on February 14, 2011

5. Merging Sunspots from HMI in Continuum on October 24-28, 2010

6. Prominence Eruption and active region from AIA in 304 Angstroms on April 30, 2010

7. Solar activity and plasma loops from AIA in 171 Angstroms on March 4-8, 2011

8. Flowing plasma from AIA in 304 Angstroms on April 19, 2010

9. Active regions from HMI in Magnetogram on March 10, 2011

10. Filament eruption from AIA in 304 Angstroms on December 6, 2010

11. CME start from AIA in 211 Angstroms on March 8, 2011

12. X2 flare from AIA in 304 Angstroms on February 15, 2011

HEALTHY LIVING EXTEND LIFE

Healthy lifestyle lengthens life Healthy life prolongs life through lengthening of telomeres.


Chromosomes are at different stages of the cell cycle, telomeres are painted red. (FotoTraveller's soul.)

One of the main factors of aging is the shortening of telomeres - the end portions of chromosomes. Telomeres are necessary in order to protect the semantic segments of DNA in the fission: the enzyme that copies DNA, it does not finish the extreme nucleotides, and that does not happen to the coding sequences, chromosomes carry at their ends meaningless telomeres. Since telomeres are not dimensionless, the cell can divide and double their DNA limited number of times.

Upon reaching this limit, the cells stop dividing and begin to die due to various injuries in the proteins and DNA that have arisen in part because of damage lost the telomeres of chromosomes.

Cells have the enzyme telomerase, which can finish building the telomeres and thus prolong the life of cells, giving her the opportunity to share more and more. Telomerase, however, is not synthesized in all cells of our body, but only in those that are supposed to be immortal (or relatively immortal) - in the genital and stem. In most normal somatic cells, telomerase is silent.

It may also happen that the system updates can not keep up telomere shortening them. It is believed that the rate of telomere shortening is not constant but depends on many factors, which are realized through epigenetic mechanisms, and can give it a shortening downright fatal speed.

Do not forget, too, that the shortening of telomeres and cell attempts to do something about it can lead to cancerous degeneration when chromosomal damage as a result of attempts to circumvent the shortening of chromosome tails, together with activated telomerase. In addition, telomere shortening effect on the emergence of various forms of cardiovascular disease, diabetes, osteoporosis, etc.

At one time it was thought that the shortening of telomeres and their - it's something like fate, that these parameters are entered into our molecular genetic car and can not be changed, bad genes have bad genes. Then it became clear that the bad genes in this sense can also worsen: telomeres were sensitive to stress. And found that external factors can not only accelerate telomere shortening, but extend blocked.

This was in the pages of The Lancet Oncology researchers wrote University of California, San Francisco (USA).

Professor Dean Ornish and his colleagues for five years was observed in 35 men with early stage prostate cancer. Ten of them at the time of observation had to change their way of life. They switched to a diet consisting mainly of vegetables, fruits and whole grains, and low in fat and refined carbohydrates. Six times a week for half an hour they walked. And regularly struggled with stress through meditation, yoga elements and breathing exercises.

In general, they had to live a healthy lifestyle, but without too much effort for him. In addition, they regularly attended support group sessions, communicating with each other and collectively removing stress.

At the same time, scientists monitored the telomere length and telomerase activity in all subjects. And it turned out that those who are fed on a diet and be physically active on a regular basis, the telomeres were about 10% longer. It should be emphasized: the authors say the work is to extend the telomere, not that they just become slower shorter.

And the people diligently followed the advice, the more he had expressed this elongation.

Those who are at a healthy lifestyle is not passed, the telomeres, on the contrary, shortened, and that the shortening of the end of the five-year period was approximately 3%.

As for telomerase activity, it decreased in both groups, but to a much lesser extent (as you might guess) physically active experimental. In this case, the commitment of a healthy way of life fall in activity of the enzyme was independent.

Here we can recall that these 35 men actually had a tumor of the prostate, but the researchers took samples at the telomeres of blood, not from tumor tissues. According to the authors, the results can be generalized to healthy people, but that confidence is still very desirable to confirm the experiment.

In addition, it would be interesting to find out what the molecular mechanisms connecting a healthy lifestyle and telomere length and whether or not such a telomere elongation slows aging.

Another weak side research - a very small sample of 35 people. It is hoped that these results will be cross-checked with the much used? Larger number of participants.

And if the findings are confirmed, it would mean that we ourselves can be - at least to some degree - masters of their telomeres.

However, as can be seen in the way that we can lengthen the telomeres, it is not unusual: it is hard to find anyone who has not heard about the importance of this way of life, and in this case, the researchers only add points to his credit. Perhaps those who adhere to a healthy lifestyle, live longer thanks to including lengthening telomeres.

How To Live Life Healthily

Depression can hop out

Depression can run out
Depression can run out.

Not literally, but in the sense of dignified exercise of any type.

If you engage in cyclical exercise, depression weakens the quality of life increases.

On the contrary, the cessation of physical activity is associated with a refund or increasing depression.

A healthy lifestyle with a full physical activity, it turns out, there is no alternative, and depression too.

Physical exercise - the most powerful, most effective, most healthy antidepressant.

So we take into service, remembering also that depression and others like her state of meteopaticheskie cohort.
