 Datele oferite de Organizatia Mondiala a Sanatatii demonstreaza ca aproape o suta de milioane de oameni din intreaga lume sufera de psoriazis, o maladie nu atât grava, cât mai ales suparatoare, careia, in ciuda eforturilor depuse de cercetatori si medici, nu i s-a putut gasi un remediu suta la suta eficient. Dar se pare ca acolo unde medicina da gres, Natura are succes. Dovada cea mai elocventa? In Turcia, pentru tratarea psoriazisului bolnavii apeleaza nu la doctori, ci la... pesti!

Poate ca pestisorii din familia Cyprinidae nu or avea cei sase ani de medicina, dar in domeniul tratarii psoriazisului si al altor boli de piele, nimeni nu e mai priceput decât ei. Si daca nu credeti si suferiti de asemenea maladii, nu aveti decât sa va luati concediu medical si sa mergeti in orasul turcesc Kangal. Situat la circa 500 km est de Ankara, orasul se afla intr-o splendida oaza, brazdata de câteva izvoare cu apa termala, a carei temperatura atinge 36 de grade. Aceasta apa constituie un mediu de viata excelent pentru pestisorii numiti de localnici "clevetitori", din pricina faptului ca obisnuiesc sa se adune cu zecile in jurul zonelor afectate de psoriazis, inghesuindu-se unii intr-altii, de parca ar purta o discutie aprinsa.

De fapt, ei se hranesc cu scuamele provocate de boala, pe care le aspira ca niste veritabile aparate deliposuctie! Ingrijitorii bazinelor unde traiesc acesti pesti mai lacomi decât piranha au grija ca ei sa fie in permanenta flamânzi. Lipsa hranei face ca, odata ce un om suferind de psoriazis intra in apa, "clevetitorii" sa se napusteasca asupra lui si sa-i devoreze, efectiv, pielea afectata de psoriazis, fara a se atinge insa deloc de pielea sanatoasa.

Un tratament miraculos

 Mai intâi, pestii ataca placardele de psoriazis si indeparteaza straturile groase, apoi rod straturile mai subtiri, inmuiate de apa calduta si sug pielea, eliminând orice urma a bolii. In aceasta faza, organismul lor secreta o substanta care are rolul de a coagula sângele, oprind micile hemoragii ce se pot declansa la nivelul pielii. In timpul curei, pacientii trebuie sa bea cel putin trei pahare cu apa calduta dimineata, pe stomacul gol, sa intre in bazin dupa micul dejun, stând patru ore, apoi sa intre iarasi, dupa-amiaza, pentru alte patru ore.

Totodata, pe perioada celor 21 de zile cât dureaza tratamentul, suferinzii de psoriazis nu au voie sa consume alcool sau sa ia medicamente. Un studiu efectat in 1990 a demonstrat ca 52% dintre bolnavi se vindecasera total de psoriazis, la 48% mai aveau inca doar câteva placarde, putin intinse, pe trup, dupa o singura cura de trei saptamâni, desfasurata aici. Vestea despre acest remediu miraculos s-a raspândit in toata lumea si asa se face ca anual mii de turisti vin din Europa, Asia sau America sa se lase "ciupiti" de pestisorii-doctori.

Iar faptul ca, dupa ce s-au reunit aici pentru un congres maraton, in 1993, zeci de somitati medicaledin Turcia si Europa au certificat eficacitatea tratamentului cu pestisori, a sporit si mai tare renumele locului, determinându-i pe doctorii de pretutindeni sa le recomande bolnavilor de psoriazis o cura la Kangal.

Nei dintorni di Berchtesgaden si trova la zona di Obersalzberg, famosa per la villeggiatura alpina, luogo ameno di cui si innamorò Hitler negli anni '20 e dove costituì con i gerarchi del partito - Göring, Hess, Bormann, Speer e Göbbels - una sorta di quartier generale-bunker per le vacanze.
 
Questo villaggio a circa 1.000 metri d'altezza, dove era ambitissimo essere invitati, è stato bombardato alla fine del '45 e raso al suolo nel 1952. Nell'area si trova oggi un centro di documentazione sul nazismo. Hitler soggiornò qui con Eva Braun in una villetta da lui battezzata "Berghof". Nel 1938 ebbe in dono dai gerarchi del partito per il suo 50.mo compleanno (che compirà il 20 aprile 1939) il celeberrimo "Nido dell'Aquila", uno chalet-fortezza costruito sul Kehlstein, un picco di 1.834 metri sovrastante il villaggio di Obersalzberg.

Percorrendo una strada tortuosa lunga 7 km (Kehlsteinstraße) scavata sui fianchi della montagna e attraversando un tunnel di 124 metri si giunge ad un avveniristico ascensore che porta all'interno dello chalet - il cui nome ufficiale è Kehlsteinhaus - dopo 124 metri di salita all'interno della montagna.
 
La costruzione fu completata in due anni di intenso lavoro, di enormi difficoltà tecniche e con un notevole dispendio di risorse umane (circa un migliaio le persone coinvolte nel progetto).
Questa residenza di montagna (oggi è un ristorante-belvedere), circondata da balconate che permettono una stupenda vista sul Königssee e sul Watzmann (che con 2713 metri di altezza è la seconda vetta più alta della Germania), fu arredata utilizzando marmi e legni pregiati. Nel grande atrio ottagonale fu installato un camino di marmo rosso cupo con venature bianche, dono di Mussolini al Führer.

 
Hitler visitò ufficialmente questa fortezza nel 1938 (16, 17, 19 settembre; 16, 17, 18, 21, 23, 24 ottobre) e nel 1939 (4 gennaio; 15 luglio; 11 e 12 agosto). Le cronache riportano anche tre visite non ufficiali, anche se è ignoto il loro numero totale. Pur colpito dall'edificio e dal panorama, Hitler non nutrì un sentimento speciale per il luogo, anche a causa dell'aria troppo rarefatta. Dopo lo scoppio della seconda guerra mondiale il Führer non soggiornò più nella Kehlsteinhaus, mentre continuò a frequentare il sottostante Berghof.
 
Per raggiungere il Nido dell'Aquila, salvato dal bombardamento degli alleati nel 1945 e dalla distruzione del '52 ed aperto al pubblico da metà maggio a metà ottobre, si deve arrivare ad Obersalzberg (presso Berchtesgaden) dove con dei bus si può giungere sul piazzale antistante l'ingresso al tunnel che porta al sopraccitato ascensore - decorato con specchi, ottoni e sedili in pelle verde - che tuttora permette ai turisti di salire in 41 secondi là dove si rilassava con la sua Eva Braun l'uomo più odiato del XX secolo.

Researchers in Germany have developed the world's thinnest "pico" video projector.

The prototype device contains an array of carefully shaped microlenses, each with its own miniature liquid-crystal display (LCD). The device is just six millimeters thick, but it produces images that are 10 times brighter than would normally be possible with such a small device.

Handheld pico projectors can be used to display movies, maps, or presentations on nearby surfaces. But the projections can be difficult to view in direct sunlight because the light source isn't very powerful. The new lens system is small enough to be incorporated into a slim smart phone.

Increasing the brightness of a projection normally means increasing the area of the light source used, says Marcel Sieler, a researcher at the Fraunhofer Institute for Applied Optics and Precision Engineering in Germany. Sieler was involved with developing the prototype. But to increase the area in this way requires a thicker lens to focus the larger image. "As the area of the light source increases, so does the volume of the lens," says Sieler. The result is a much bigger projector.

Sieler and colleagues created a novel type of lens that focuses light from a relatively large light source while remaining thin. The prototype video projector consists of 45 microlenses colored red, green, or blue. Each lens has an LCD with 200 by 200 pixels behind it. The light passing through each LCD is focused through a lens, and together each image is superimposed on top of each other to produce the final image. The design was inspired by a type of microlens array known as a "fly's eye condenser," which is normally used to mix light from different sources.

April 7, 2011. In his latest blog post, Bradley’s attorney David Coomb’s reports that:

“the defense has been working to facilitate an official visit for Congressman Dennis Kucinich, Mr. Juan Mendez (the United Nations Special Rapporteur on Torture), and a representative from Amnesty International.”

Allowing such visits would not only provide the opportunity for an expert investigation into Bradley’s conditions of incarceration, but would also help raise the profile of Bradley’s case in the national media.  The above officials have finally been granted the right to visit Bradley, but with a twist.

“The Quantico Brig Order P1640.1C, paragraph 3.17 allows two types of visitors for a detainee, ‘authorized’ and ‘official,’” explains Coombs.  ”The difference between them is described here in the Brig rule.”

Unexpectedly, the officials are only being granted “authorized” visits with Bradley.  A key difference between the two types of visits is that an authorized visit, which is normally granted to family members and friends, is subject to careful monitoring, including video and tape recording.  Evidence from these visits can be used against Bradley in court.

“The Government’s position is that the above individuals are not entitled to an official visit because none of these individuals are conducting ‘official government business.’”  Yet, none of these individuals have “established a proper relationship with the prisoner prior to confinement,” as required under the Brig rule for “authorized” visits.

Somehow an investigation by the United National Special Rapporteur on Torture doesn’t qualify as official government business.

Check out our toolkit for the addresses of the Quantico officials, if you’d like to let them know how you feel about their decision.

Studiile efectuate de o echipa de cercetatori americani de la Harvard Medical School din Boston, legate  de istoria indepartata a stramosilor nostri, au relevat un fapt stupefiant. Stramosii omului si cei ai cimpanzeului s-au "iubit" timp de milenii sau, poate, chiar milioane de ani, inainte de a avea loc o separare definitiva, mult mai recenta decât se credea.

Antropologii americani apreciaza ca cele doua linii s-au separat in urma cu 6,3 milioane de ani, cel mult, sau, cel putin, in urma cu 5,4 milioane de ani, dar aceasta separare nu i-a impiedicat sa faca un schimb de gene. Informatia e perceptibila in special la nivelul cromozomilor x (cromozomi sexuali feminini) ale caror similitudini par sa releve faptul ca cele doua specii s-au incrucisat timp indelungat.

"Divortul" final ar fi intervenit dupa o lunga perioada de "metisaj" care a durat probabil 4 milioane de ani. "Studiul a dat rezultate neasteptate in ceea ce priveste modul in care ne-am separat de stramosii nostri cei mai apropiati din acea vreme: cimpanzeii. Am constatat faptul ca structura populatiei care a existat in perioada aparitiei noilor specii era diferita de orice populatie moderna de maimute. Atunci s-a petrecut ceva cu totul special", a declarat coordonatorul studiilor, David Reich.

 Rezultatele obtinute, relanseaza problema statutului hominizilor, considerati drept cei mai vechi stramosi ai omului, cum ar fi sahelantropul (alias omul din Tumai), din urma cu 6-7 milioane de ani, Orrorin, din urma cu 6 milioane de ani sau ardipithecul, din urma cu 5,5 milioane de ani. De mentionat faptul ca enigma originii este in continuare "nestirbita". Daca in cazul stramosilor omului au fost descoperite numeroase fosile, nici un os (cu exceptia câtorva dinti) care sa fie atribuit primilor cimpanzei (sau gorile) nu a fost descoperit pâna in prezent.

Pe de alta parte, descifrarea completa a genomului cimpanzeului nu a condus la obtinerea informatiilor scontate. S-a confirmat insa faptul (de care multi oameni de stiinta se indoiau) ca cele doua specii sunt identice din punct de vedere genetic, in proportie de 99%, aceasta descoperire nepermitând insa definirea in termeni precisi a specificitatii omului.

La città di Berchtesgaden (ca. 8.000 abitanti) è situata nel sud-est della Baviera, a pochi km dal confine con l'Austria; fino al 1809 era sotto il dominio del potente principe-vescovo di Salisburgo. E' una tipica città della Baviera, con un elegante e molto colorato centro storico: case riccamente decorate da affreschi e fiori, negozi di tipici prodotti locali, birrerie...

Questa celebre località alpina si trova ai piedi del monte Watzmann (2.713 m) e vanta un'antica e gloriosa storia: per secoli è stata infatti uno dei capisaldi della via del sale, grazie alle miniere saline che tuttora si possono visitare con un avventuroso percorso guidato che comprende la visita ad un lago sotterraneo, ed un importante feudo religioso.
 
A partire dal 1102 i Canonici Agostiniani edificarono un vasto complesso conventuale e la Stiftkirche (abbazia di St. Peter und Johannes), caratterizzata da un esterno in stile romanico e da un severo interno in stile gotico. Con la secolarizzazione di inizio Ottocento, il convento è passato ai Wittelsbach che lo hanno trasformato nel 1810 in una residenza per le vacanze.
Ancora oggi una parte del castello è abitata dai membri dell'ex famiglia reale bavarese mentre una parte è aperta al pubblico. Dal 1922 al 1933 qui ha vissuto il principe ereditario Rupprecht (1869-1955), figlio di re Ludwig III. Le visite guidate si svolgono da Pentecoste al 15 ottobre dalle 10 alle 12 e dalle 14 alle 16 (tranne sabato) mentre dal 16 ottobre a Pentecoste solo alle 11 e alle 14 (tranne sabato, domenica e festivi).

 
Da vedere inoltre la barocca Pfarrkirche, il Rathaus (municipio) e la Franziskanerkirche, costruita nel 1480 per gli Agostiniani e passata ai Francescani nel 1695.
 
Fuori dall'abitato meritano una visita la parrocchiale di Ramsau, nell'omonimo paese, e il piccolo e grazioso santuario di Maria Gern, due attrazioni-cartolina della Baviera spesso ritratte in libri e depliant turistici come simbolo del perfetto connubio che regna nella regione tra arte e natura.

Socio-economic disparities in diet patterns and nutrient intake are well documented in research. People with lower incomes and less education typically have less healthful eating habits than people with higher incomes and more education. But little is known about the extent to which those disparities are driven by higher monetary costs of nutritious foods.

Now, a new study from University of Washington researchers concludes, for the first time, that socio-economic disparities in diet quality are directly affected by diet costs. The study, "Are socio-economic disparities in diet quality explained by diet costs?" is published in advance online in the Journal of Epidemiology & Community Health.

UW researchers have previously found that better quality diets are more costly than less nutritious diets, and that there is a rising disparity in the price of healthful foods. "The twist with this new study is that we've connected the dots that could explain why people in a lower socio- economic status have less nutritious diets," said Pablo Monsivais, UW acting assistant professor of epidemiology.

Monsivais, with Program Manager Anju Aggarwal and UW Professor Adam Drewnowski, studied data of more than 1,300 men and women from the Seattle Obesity Study, a population-based study of food access, diet quality and health among King County, Wash. residents.

The researchers first looked at how diet cost was associated with educational attainment and household income, two indicators of socio-economic position. They used statistical methods to control for total calorie intake and other factors. The average diet cost was higher for people with higher educational attainment and higher household income. People with lower educational attainment had diet costs that were an average of $1.09 per day lower than that of persons in the highest group ($8.19 to $9.28 per day).

People with the highest educational attainment or income also enjoyed the most nutritious diets. Those in the highest income group reported diets that were on average 9.3 points higher in nutrient density than diets reported by the lowest income group (96.6 versus 87.3 percent), after controlling for dietary and demographic factors. However, after taking the cost of food into account, the difference in dietary nutrient density between the highest and lowest groups shrank to 1.4 percentage points (93.0 versus 91.6 percent). "These results tell us that cost is a major factor in explaining the differences in eating habits between people of lower and higher socioeconomic level" said Monsivais.

Monsivais said the Seattle study should be replicated on a wider, more diverse (in terms of education, income) section of Americans--or in another country. "What is the average person's concept of nutritious food, too?" Monsivais said. "We don't know that, and it might explain some amount of the variation we found."

The Centers for Disease Control and Prevention's NHANES (National Health and Nutrition Examination Survey) could also be tapped to further explore the socio-economic question, he said.

Study results provide fodder for new and different nutrition policy and interventions, which for the last several decades have been mostly premised on the idea that poor diets were due to a lack of nutrition knowledge or insufficient motivation for healthy eating. "The most universal policy change or intervention would be to rethink how we encourage the production of foods," said the researcher. "In this country, we have a very expensive agricultural subsidy program that targets a limited range of foods that are not part of a nutritious diet. We do not support fresh produce or seafood, but instead support the production of inexpensive sugars, fat and refined grains. We need to align public health priorities with agricultural policies because it affects the largest number of people."

In addition, Monsivais said states could be more creative with public school food programs and other nutrition efforts that impact low-income people. California has experimented with an electronic benefits transfer program (food stamps) that rewards people who buy fresh produce, which makes having a healthier diet easier and more affordable.

Food retailers and grocers could also help consumers make healthier choices, said Monsivais. When you swipe a "member" card at a local store, it could be used in a helpful and healthful way, offering up coupons for items that are nutrient-rich. "If we could overlay a health lens on top of the member cards and make recommendations that are aligned with the way consumers eat and incentives, we could make it interesting for people."

  250 of the US's most eminent legal scholars have signed a letter protesting the treatment of accused Wikileaks source Pfc. Bradley Manning. Manning is accused of passing thousands of secret government documents to WikiLeaks and has been charged with "aiding the enemy", a capital offense. As reported in the Guardian, the letter says that Manning is being held in "degrading and inhumane conditions" that are not only illegal and unconstitutional, but could amount to torture.

The letter was published in the New York Review of Books and written by Bruce Ackerman of Yale Law School and Yochai Benkler of Harvard Law School. This excerpt from the letter details the conditions Manning is held in and charges that these violate the US constitution (I have added emphases in italics):

For nine months, Manning has been confined to his cell for twenty-three hours a day. During his one remaining hour, he can walk in circles in another room, with no other prisoners present. He is not allowed to doze off or relax during the day, but must answer the question "Are you OK?" verbally and in the affirmative every five minutes. At night, he is awakened to be asked again "Are you OK?" every time he turns his back to the cell door or covers his head with a blanket so that the guards cannot see his face. During the past week he was forced to sleep naked and stand naked for inspection in front of his cell, and for the indefinite future must remove his clothes and wear a "smock" under claims of risk to himself that he disputes.

The sum of the treatment that has been widely reported is a violation of the Eighth Amendment's prohibition of cruel and unusual punishment and the Fifth Amendment's guarantee against punishment without trial. If continued, it may well amount to a violation of the criminal statute against torture, defined as, among other things, "the administration or application…of… procedures calculated to disrupt profoundly the senses or the personality."

... President Obama was once a professor of constitutional law, and entered the national stage as an eloquent moral leader. The question now, however, is whether his conduct as commander in chief meets fundamental standards of decency. He should not merely assert that Manning's confinement is "appropriate and meet[s] our basic standards," as he did recently. He should require the Pentagon publicly to document the grounds for its extraordinary actions -- and immediately end those that cannot withstand the light of day.

The signatories of the letter include:

  • Bill Clinton's former labour secretary Robert Reich
  • President Theodore Roosevelt's great-great-grandson Kermit Roosevelt
  • the former president of the American Civil Liberties Union Norman Dorsen
  • the novelist Kwame Anthony Appiah
  • Laurence Tribe, a Harvard professor who is "considered to be America's foremost liberal authority on constitutional law" and who once taught constitutional law to Barack Obama and was a key backer of his 2008 presidential campaign

A full list of scholars who have signed the letter can be found here.

Benkler stated in the Guardian that "it is incumbent on us as citizens and professors of law to say that enough is enough." He added that the treatment Manning is being subjected to is being used "warning to future whistleblowers" and that it is "tragic that it is Obama's administration that is pursuing whistleblowers and imposing this kind of treatment."

Also, Ackerman points out that, under the Pentagon's own rule book, the Uniform Code of Military Justice, Manning's jailers could be prosecuted for abusing him according to Article 93 of the code, that "any person who is guilty of cruelty toward any person subject to his orders shall be punished."

Amnesty International and other human rights organizations have denounced Manning's harsh treatment, which the United Nations' rapporteur on torture is also investigating.

I hope President Obama takes this letter very seriously. The letter notes that Wikileaks has "touched every corner of the world" and emphasizes that the whole world watches America and observes what it does, not what it says -- and the treatment of Bradley Manning does not speak well for us.

You can take action and sign this petition to end the inhumane treatment of Bradley Manning.

In coastal desert countries like the United Arab Emirates fresh, clean water is a lacking resource. Desalination is a necessary process to receive fresh water, but it often harms the environment by returning concentrated saline back to the ocean. Abu Dhabi's Environment Agency recently announced that they have developed a new solar-powered desalination system that would cut costs and be more eco-friendly.

In desert areas like the Emirates, dust and high temperature often impair the efficiency of solar panels in existing desalination plants. New technologies remedy these problems while reducing the cost of water treatment. In a press release, the agency said that two pilot sites, in Sweihan and Hameem, have shown that the negative environmental impact of desalination can be reduced, along with operating costs. Each plant is capable of producing about 35 kilowatts per hour, having a total capacity of 1050 kilowatt/hour.

Trials of the new solar power system are being tested at 30 different locations within the country. If the new process proves to be successful, Saudi Arabia and other countries will begin to use the system.

Desalination is the most effective way of cleaning water, and several plants already exist in the United Arab Emirates. However, the process can have adverse environmental impact, mainly concentrated saltwater being returned to the sea and killing marine life. New systems like the one developed by the UAE can eliminate or mitigate this problem, resulting in the same amount of clean water but with less damage to the environment.

 In anii ‘60, o omenire intreaga visa cu ochii deschisi la colonizarea intregului Sistem Solar. A trecut de atunci jumatate de secol, dar astronautii de pe Terra nu au ajuns prea departe, desi administratia de la Washington promite de mai bine de zece ani ca va trimite echipaje umane pe Marte... Totusi, "evadarea" spre alte planete, si chiar pe alte sisteme solare pare sa fie unica sansa de salvare pentru noi, pamântenii, daca vrem sa supravietuim - cel putin aceasta este opinia savantului britanic Stephen Hawking.

Renumitul om de stiinta, complet paralizat si "vorbind" prin intermediul unui computer special, a emis aceasta ipoteza saptamâna trecuta, in cadrul unei conferinte desfasurate la Hong Kong. Savantul, care a venit in Asia pentru o serie de prelegeri a declarat ca supravietuirea rasei umane depinde de abilitatea ei de a descoperi noi "locuinte" oriunde in Univers, in conditiile in care riscurile ca un dezastru de proportii sa distruga Terra este tot mai ridicat.

 Oamenii ar trebui sa aiba o baza permanenta pe Luna in urmatorii douazeci de ani si o colonie pe Marte peste cel târziu patru decenii. "Nu vom putea insa niciodata sa gasim un loc la fel de minunat ca Pamântul, pâna nu vom depasi granitele Sistemului Solar." Hawking a mai precizat ca, daca oamenii vor evita sa se extermine intre ei in urmatorul secol, ei ar putea sa construiasca asezari spatiale unde sa traiasca, fara sprijin de pe Terra. "Este esential, pentru rasa umana, sa porneasca mai repede la colonizarea Cosmosului, daca vrea sa-si asigure supravietuirea ca specie. Viata pe Pamânt este tot mai amenintata sa dispara din cauza unei catastrofe, fie a unei bruste incalziri globale, fie a unui razboi nuclear, a unui virus generat de ingineria genetica sau a cine stie carui pericol, pe care acum nici macar nu ni-l imaginam."

In cadrul aceleiasi prelegeri, Hawking a mai anuntat ca, alaturi de fiica lui, va scrie o carte pentru copii, care va descrie minunile Cosmosului, un fel de "Harry Potter cutreiera Universul"... Unul dintre cei mai mari fizicieni teoreticieni ai timpurilor moderne, Hawking a intreprins cercetari fundamentale asupra gaurilornegre si a originii Universului, lansând ipoteza ca spatiul si timpul nu au nici inceput, nici sfârsit. Opiniile exprimate de savantul britanic au stârnit reactii dintre cele mai diverse. Alan Guth, profesor de fizica la Institutul de Tehnologie din Massachusetts spune ca ultimele observatii ale lui Hawking reprezinta o surpriza pentru lumea stiintifica, intrucât preocuparile savantului britanic erau mult mai putin "pamântesti".

"Este o noua arie de preocupari pentru el, care nu poate decât sa ne surprinda. Daca s-ar referi la urmatoarea suta de ani si dincolo de acel moment, mi s-ar parea mai credibil sa considere spatiul ca ultim colac de salvare pentru omenire. Dar nu vad sa existe posibilitatea ca in urmatorii 50 de ani stiinta si tehnologia sa ne ajute sa supravietuim mai usor pe Marte sau pe Luna, decât pe Pamânt. Eu cred ca ar fi mai usor sa construim baze subterane in Antarctica, de pilda, decât sa realizam cladiri pe Luna", afirma Guth.
