3 things that do not make sense: #4

4 Belfast homeopathy results

MADELEINE Ennis, a pharmacologist at Queen's University, Belfast, was
the scourge of homeopathy. She railed against its claims that a
chemical remedy could be diluted to the point where a sample was
unlikely to contain a single molecule of anything but water, and yet
still have a healing effect. Until, that is, she set out to prove once
and for all that homeopathy was bunkum.

In her most recent paper, Ennis describes how her team looked at the
effects of ultra-dilute solutions of histamine on human white blood
cells involved in inflammation. These "basophils" release histamine
when the cells are under attack. Once released, the histamine stops
them releasing any more. The study, replicated in four different labs,
found that homeopathic solutions - so dilute that they probably didn't
contain a single histamine molecule - worked just like histamine.
Ennis might not be happy with the homeopaths' claims, but she admits
that an effect cannot be ruled out.

So how could it happen? Homeopaths prepare their remedies by
dissolving things like charcoal, deadly nightshade or spider venom in
ethanol, and then diluting this "mother tincture" in water again and
again. No matter what the level of dilution, homeopaths claim, the
original remedy leaves some kind of imprint on the water molecules.
Thus, however dilute the solution becomes, it is still imbued with the
properties of the remedy.

You can understand why Ennis remains sceptical. And it remains true
that no homeopathic remedy has ever been shown to work in a large
randomised placebo-controlled clinical trial. But the Belfast study
(Inflammation Research, vol 53, p 181) suggests that something is
going on. "We are," Ennis says in her paper, "unable to explain our
findings and are reporting them to encourage others to investigate
this phenomenon." If the results turn out to be real, she says, the
implications are profound: we may have to rewrite physics and
chemistry.

13 things that do not make sense: #3

3 Ultra-energetic cosmic rays

FOR more than a decade, physicists in Japan have been seeing cosmic
rays that should not exist. Cosmic rays are particles - mostly protons
but sometimes heavy atomic nuclei - that travel through the universe
at close to the speed of light. Some cosmic rays detected on Earth are
produced in violent events such as supernovae, but we still don't know
the origins of the highest-energy particles, which are the most
energetic particles ever seen in nature. But that's not the real
mystery.

As cosmic-ray particles travel through space, they lose energy in
collisions with the low-energy photons that pervade the universe, such
as those of the cosmic microwave background radiation. Einstein's
special theory of relativity dictates that any cosmic rays reaching
Earth from a source outside our galaxy will have suffered so many
energy-shedding collisions that their maximum possible energy is 5 ×
1019 electronvolts. This is known as the Greisen-Zatsepin-Kuzmin
limit.

Over the past decade, however, the University of Tokyo's Akeno Giant
Air Shower Array - 111 particle detectors spread out over 100 square
kilometres - has detected several cosmic rays above the GZK limit. In
theory, they can only have come from within our galaxy, avoiding an
energy-sapping journey across the cosmos. However, astronomers can
find no source for these cosmic rays in our galaxy. So what is going
on?

One possibility is that there is something wrong with the Akeno
results. Another is that Einstein was wrong. His special theory of
relativity says that space is the same in all directions, but what if
particles found it easier to move in certain directions? Then the
cosmic rays could retain more of their energy, allowing them to beat
the GZK limit.

Physicists at the Pierre Auger experiment in Mendoza, Argentina, are
now working on this problem. Using 1600 detectors spread over 3000
square kilometres, Auger should be able to determine the energies of
incoming cosmic rays and shed more light on the Akeno results.

Alan Watson, an astronomer at the University of Leeds, UK, and
spokesman for the Pierre Auger project, is already convinced there is
something worth following up here. "I have no doubts that events above
1020 electronvolts exist. There are sufficient examples to convince
me," he says. The question now is, what are they? How many of these
particles are coming in, and what direction are they coming from?
Until we get that information, there's no telling how exotic the true
explanation could be.

"One possibility is that there is something wrong with the Akeno
results. Another is that Einstein was wrong"

¡Electra Shock!

Noche de sábado, Juanma, Alex, Flopy y yo vamos al teatro Lorange a ver Electra Shock, adaptación de la obra de Sófocoles... Flopy tiene esto para decir:

¡Qué salvada de noche que fué la obra!

Música poderosa, mucho movimiento, franeleo entre mismos géneros, mucho cuero en proporción a la poca ropa... ¡Levantó los ánimos y el líbido!




Las expectativas fueron superadas y hasta nos cambiaron el programa original. De griego tenía los nombres de los personajes nomás... Más allá de no haberse estrenado en el ambiente para la que fué ideada (problemas de habilitación), lograron darle la hiperquinesia que buscaban. Corridas, saltos, levantadas en brazo, personajes en los pasillos del teatro y gritos, muchos gritos. Fué una vorágine de personajes extraños y todos muy fuertes. ¡Hasta los secundarios se
llevaron aplausos!

La música super poderosa todo el tiempo, nada de baladas o romanticismos. Todo "eléctrico" y estridente. Hubo un par de temas cantados en play-back con la participación de todo el elenco,
reminiscencia del coro griego suponemos, que nos dejaron la melodía en la cabeza el resto de la noche y parte del otro día también. La iluminación fué lo único que no me gustó demasiado, creo que podrían haber conseguido mejores efectos con el mismo juego de luces, pero es un detallecito casi imperceptible en medio de tanto caos.

Las actuaciones... muy energéticas, TODAS. Esos chicos van a necesitar algo fuerte para lograr la calma después del espectáculo. Muy buena la perfrmance de Carolina Fal, mantuvo buena tensión toda la obra. Los gags del resto de los personajes fueron oportunos y bien llevados, logrando hacer que el público se ria de forma espontánea a pesar de la tensión del resto de la obra.

Qué decir... fué un SHOCK ELÉCTRICO... para que volvamos a la vida esa
noche, al mejor estilo Frankenstein.

13 things that do not make sense: #2

2 The horizon problem

OUR universe appears to be unfathomably uniform. Look across space
from one edge of the visible universe to the other, and you'll see
that the microwave background radiation filling the cosmos is at the
same temperature everywhere. That may not seem surprising until you
consider that the two edges are nearly 28 billion light years apart
and our universe is only 14 billion years old.

Nothing can travel faster than the speed of light, so there is no way
heat radiation could have travelled between the two horizons to even
out the hot and cold spots created in the big bang and leave the
thermal equilibrium we see now.

This "horizon problem" is a big headache for cosmologists, so big that
they have come up with some pretty wild solutions. "Inflation", for
example.

You can solve the horizon problem by having the universe expand
ultra-fast for a time, just after the big bang, blowing up by a factor
of 1050 in 10-33 seconds. But is that just wishful thinking?

"Inflation would be an explanation if it occurred," says University of
Cambridge astronomer Martin Rees. The trouble is that no one knows
what could have made that happen.

So, in effect, inflation solves one mystery only to invoke another. A
variation in the speed of light could also solve the horizon problem -
but this too is impotent in the face of the question "why?" In
scientific terms, the uniform temperature of the background radiation
remains an anomaly.

"A variation in the speed of light could solve the problem, but this
too is impotent in the face of the question 'why?'"

13 things that do not make sense: #1

The placebo effect

DON'T try this at home. Several times a day, for several days, you induce pain in someone. You control the pain with morphine until the final day of the experiment, when you replace the morphine with saline solution. Guess what? The saline takes the pain away.

This is the placebo effect: somehow, sometimes, a whole lot of nothing can be very powerful. Except it's not quite nothing. When Fabrizio Benedetti of the University of Turin in Italy carried out the above experiment, he added a final twist by adding naloxone, a drug that blocks the effects of morphine, to the saline. The shocking result? The pain-relieving power of saline solution disappeared.

So what is going on? Doctors have known about the placebo effect for decades, and the naloxone result seems to show that the placebo effect is somehow biochemical. But apart from that, we simply don't know.

Benedetti has since shown that a saline placebo can also reduce tremors and muscle stiffness in people with Parkinson's disease (Nature Neuroscience, vol 7, p 587). He and his team measured the activity of neurons in the patients' brains as they administered the saline. They found that individual neurons in the subthalamic nucleus (a common target for surgical attempts to relieve Parkinson's symptoms) began to fire less often when the saline was given, and with fewer "bursts" of firing - another feature associated with Parkinson's. The neuron activity decreased at the same time as the symptoms improved: the saline was definitely doing something.

We have a lot to learn about what is happening here, Benedetti says, but one thing is clear: the mind can affect the body's biochemistry. "The relationship between expectation and therapeutic outcome is a wonderful model to understand mind-body interaction," he says. Researchers now need to identify when and where placebo works. There may be diseases in which it has no effect. There may be a common mechanism in different illnesses. As yet, we just don't know.

Aseguran que en México el Pachuca humilló a Boca

INFOBAE - Aseguran que en México el Pachuca humilló a Boca: "Aseguran que en México el Pachuca humilló a Boca

La prensa mexicana desplegó hoy un clima exitista ante la victoria de anoche por 3 a 1, por el grupo 8 de la Copa Libertadores"



El importante diario deportivo Esto tituló con grandes caractéres que "Boca se comió tres" y agregó que Pachuca respondió con fútbol a las patadas que vino a repartir el equipo visitante y consiguió un triunfo claro y contundente sobre el afamado equipo argentino".

El periódico consignó que el director técnico José Luis Trejo "que ya había enfrentado a Boca (con Cruz Azul, por la final de la Libertadores del 2001) supo perfectamente cómo plantear el partido ante el conjunto visitante".

Por su parte, El Universal señaló que "Los Tuzos callan 'Boca' de argentinos", añadiendo que "Pachuca muestra carácter para mantener en silencio al Boca Juniors y revivir en la Copa Libertadores".

"Con la varita mágica en la Copa Libertadores, José Luis Trejo activó a los ex cruzazulinos Juan Carlos Cacho y Cesáreo Victorino, fórmula que le abrió el camino para someter al histórico Boca Juniors y revivir la moral del Pachuca en el torneo internacional, con actitud, coraje y entrega", se dijo.

A su turno, La Afición tituló "Humillan a los xeneizes", y Excelsior comentó que "el cuadro hidalguista dio su mejor partido en este tiempo y derrotó a un histórico de Sudamérica".

En tanto que Crónica consideró que "Pachuca humilló a Boca. le ganó a un equipo argentino que cometió el error de dar por ganado el encuentro antes de jugarlo. Boca pagó caró el sindrome triunfal".

BUENOS AIRES BRIEFING
March 2005


News this month

Back to the party

The city's nightclubs are reopening, after a two-month closure. The city council had shut them down after 192 people died in a fire at the República Cromañón nightclub on December 31st. But at the end of February, after rigorous security checks, inspectors allowed two clubs to open and reckoned that around 40 would soon follow by the end of March.

The capital's tourism and entertainment industries have suffered under the crackdown. Musicians have had to escape the city to find clubs to perform in, and the city's formerly thriving alternative-theatre circuit has also been stymied by suddenly diligent safety inspectors. Even the Hotel Faena, one of the city's most fashionable and exclusive hotels (which opened in October), had to turn guests away for a week during tiffs with zealous inspectors. Assailed for not doing enough to avert December's disaster, the city has worked to demonstrate its toughness. The city council has beefed up controls on public venues, and the General Justice Inspectorate has decreed a ban on offshore companies operating in the capital. This is to mitigate one of the contributing factors in the República Cromañón case, in which the club's ownership was obscured by arrangements with a series of Uruguay-based companies.


Cartel air

Security officials at Barajas airport in Madrid intercepted 60 kilos of cocaine that had been shipped from Buenos Aires' main airport, Ezeiza, revealing serious breaches in security there. Though the packages were discovered in September, their existence was not made public until February. The government has blamed the air force for keeping the discovery quiet. The chief executive of Southern Winds, the airline responsible for the shipment, denounced the case in the Argentina courts in October, and blamed rogue employees. But the judge on the case suspects the incident points to larger problems in airport security, and has arrested several Southern Winds executives.

The packages had fake labels claiming they were the property of the Argentine embassy in Madrid, and were sent as unaccompanied luggage, which is prohibited. They also were not passed through the airport's scanners. Shortly after the cocaine was found, security videos that could have identified the smugglers were erased. The government, under fire for its handling of the scandal and concerned about systemic security gaps, has acted with characteristic vigour. It has removed the senior command of the air force, previously responsible for security at airports; dissolved the force's National Aeronautical Police, replacing it with a civilian force; and cancelled a joint venture between the state and Southern Winds.

In the streets again

After a lull in activity at the beginning of the year, the capital's piqueterosunemployed protestors—returned to the streets in February. In the most serious incident, a 24-year-old piquetero was arrested after attacking a car that tried to pass through a column of marchers. Demonstrators smashed several of the car's windows, covered it in dents and inflicted cuts and bruises on the occupants, including three young girls. The organisation responsible, which has ties to Quebracho, one of the city's most radical left-wing groups, later apologised, calling it “an error”. But the family of those assaulted rejected the apology, and said they would sue the government for not guaranteeing the free passage of traffic.

The attack was another blow for the image of the piqueteros, who have drawn ire after repeated roadblocks and clashes (incited by some more extreme groups). In response, the city's prosecutors have ordered a firmer crackdown, as opposed to the national government's soft approach. In a first step, prosecutors have demanded that participants not cover their faces during protests, and banned the sticks carried by the demonstrators' security forces. The piqueteros have, for now, obeyed the command.


Last ride

Norberto “Pappo” Napolitano, an Argentine rock legend, was killed in a road accident at the end of February, shortly before his 55th birthday. He was hit by a car after falling from his Harley Davidson motorbike near the city of Luján, outside Buenos Aires. Before the accident he had been drinking heavily.

BB King, an American blues legend, called Pappo “Latin America's greatest guitarist.” He was a pioneer of local rock music, briefly forming part of the legendary Abuelos de la Nada, before starting his own band, Pappo's Blues, and later launching Argentina's first heavy metal band, Riff, in 1980. During his career he recorded with virtually all the big Argentine rock bands and appeared with several American stars (including Mr King). Blunt and irascible, Napolitano had once been accused of fascism; just before he died he was being prosecuted for punching another musician. But there was a gentler side: he lived at home with his mother until her death in the 1990s. Thousands of fans turned out to salute his funeral cortege and participate in the services at the city's Chacarita cemetery.


Raising the dead

Scientists recently found the long-lost body of Facundo Quiroga, a brutal provincial leader known as the “Tigre de Los Llanos” (Tiger of Los Llanos). His burial site had been a secret for 170 years. Quiroga and his mentor, the equally tyrannical Juan Manuel de Rosas, were denounced by Domingo Sarmiento, a revered 18th-century figure, for their bloody vision of federalism in Sarmiento’s tremendously influential book “Facundo”. His coffin was found entombed in the wall of his family's crypt in the famous Recoleta cemetery. As local legend held, he had been buried standing upright and with a sword, so he could fight against Death. Historians think his burial site was kept secret to stop his many enemies from digging up and burning his remains.

Two centuries later, Quiroga continues to generate controversy. Politicians from La Rioja, his native province, demanded that his remains be sent there, alleging that the tomb where he was buried had been neglected. Burial rows are a regular topic in Buenos Aires. There were recently proposals to make a mausoleum in Buenos Aires province for General Juan Domingo Perón and his wife Evita, and to bring to Argentina the remains of Ernesto “Che” Guevara.

Until April 10th 2005

With the support of the French embassy, the Borges Cultural Centre hosts an expansive retrospective of the work of Henri Cartier-Bresson, a Parisian photographer who championed a photojournalistic style. This show features 155 of his pictures. Born in 1908, Cartier-Bresson was trained to be a painter; by 1932 he became inseparable from his Leica camera, which he wielded with a painterly eye. After documenting the liberation of Paris in 1945 (he spent three years as a Nazi prisoner-of-war), he travelled the world, mostly India and China, where he captured iconic images of Gandhi and of Mao's rise to power. Though he rejected photography for drawing in the last 25 years of his life, he has left an unrivalled body of work.
