Somalia’s struggle with rape

May 17th, 2013 No comments

Mogadishu, Somalia (CNN) — In a classroom tucked away from the world in Somalia’s capital, Mogadishu, students practice spelling.

Ranging in age from 6 to 11, these girls all have one thing in common: They have either been raped or suffered through the rape of a loved one.

Even the 6-year-old is a rape survivor. The baby of the class, she can’t quite keep up with the spelling lesson but is happy to clap along.

Next door, in the clinic adjoining the class, a 7-year-old boy and his mother are in for a checkup.

The mother was raped and then watched, helpless, as her son was molested.


Tackling sexual violence in Somalia


Sexual crimes a crisis in Somalia

Too afraid to seek help, she did what she thought would help: washed her son’s wounds with hot water and salt for four excruciating days until they were found and brought here.

The classroom and clinic are both part of the Elman Peace and Human Rights Center. Founded in 2011, it is the first rape crisis center in Somalia.

Today, the center has bases both in and outside Mogadishu, providing a haven for the spiraling number of Somali victims of sexual violence.

The figures are horrifying, with at least 1,700 women raped in camps for internally displaced people last year in Mogadishu, according to United Nations figures.

The Elman Peace and Human Rights Center was founded by the parents of Ilwad Elman in the 1990s to help child soldiers, but it closed down after her father was assassinated by warlords, forcing the rest of the family to seek refuge in Canada.

Eventually, she and her mother returned, and in 2011, the center reopened with a new focus: helping the victims of sexual violence.

For the safety of the Elman center’s staff and the victims it helps, CNN agreed not to reveal the location of the centers it visited.

Rape isn’t just happening in the camps for those forced from their homes by fighting, Ilwad Elman told CNN, but in the wider community, “which is also affected by rampant abuse of sexual and gender-based violence.”

Elman says she believes a multitude of factors are to blame, but the chief one is conflict — something that has affected every Somali during more than two decades of war.

“Rape is a well-known weapon of war, so that is one thing that is undeniable,” said Elman. “There’s also harmful traditional practices. There’s also the destroyed social protection structures that were in place” but were destroyed by conflict, she adds.

Put all these factors together, she said, and “that is why rape is so indiscriminate” in Somalia.

Social stigma

For the first time in decades, there is reason for optimism in Somalia, thanks in part to the country’s newly appointed and popular president, Hassan Sheikh Mohamud, and increased security in much of the country.

But the plight of Somalia’s women has seen little improvement.

While the center’s staff has gained some idea of the number of cases of sexual violence in Mogadishu and its surrounding area, little is known about the scale of the problem further afield.

Rape in Somalia carries huge social stigma, and after the long years of conflict, there is no way of knowing how many women are suffering in silence.

When the new president was appointed last year, his public commitment to punishing those guilty of sexual offenses had an immediate impact, said Elman.

But those advances have been undone, she said, by events since.

In February, Lul Ali Osman Barake made headlines when she reported her rape at the hands of men she says were government soldiers.

They took turns raping her, she told CNN, only stopping when they thought she was dead. But when she reported the crime, it was Barake who was arrested and convicted of defaming a government institution.

Eventually, she was freed after a huge international outcry, but she says her attackers have yet to face justice.

And, like many of the women CNN spoke to, she has no faith they ever will.

The United Nations says 70% of the rapes perpetrated in Somalia are carried out by men in military uniforms.

Somali Prime Minister Abdi Farah Shirdon admits there’s a problem but insists that it is being addressed.

“There’s been no effective government in Somalia for such a long time, and people are disorganized … but now we are organizing, and I think we’ll disconnect … from the past,” he told CNN. “We are doing everything possible, we are taking every step to ensure that women and girls are safe.

“We have nominated a new commissioner, judiciary reforms, and … we are constituting a new policy for making our women and children safer than ever.”

‘Underground network’ of women

But women’s rights activists say the damage might already have been done.

“I think it’s become a lot harder for women to report rape,” said Elman. “One clear message was sent to them: that if you do report a rape, there’s as much of a chance of you ending up in jail as a perpetrator. It has not only become harder for women who are a survivor of rape to report it, but also people working with these people to work towards ending or responding to sexual violence.

“There was a very dramatic decline in the figures for the last three months. I think it was nearly 60%.”

With public information limited and the stigma against speaking out so strong, the center has created “almost an underground network of women” to spread the word about its work, said Elman.

Some women who have been supported by the center go on to help others, letting them know through word of mouth that these services exist. Other women find their own way there or meet center staff out in the community, she said.

What makes the situation worse is that often, the same woman is raped repeatedly, by different perpetrators, said Elman.

The center can help the woman each time, but “without the government’s support and putting in place mechanisms to protect these people, there will be no end to this impunity,” she said.

Hawa, who agreed to talk to CNN as long as a pseudonym was used to conceal her identity, told how after being raped she fled her home for what she thought was a new beginning in another part of town.

In her new home — and in spite of being pregnant with the first rapist’s baby, she says — she was attacked again.

She, like Barake, has no hope that justice will ever be done.

Make the perpetrators ‘bear that burden’

The United Nations is due to send in a British-funded team of experts on sexual violence to help the Somali government establish protection mechanisms.

Delegates at an international donor conference, held this month in London by the UK and Somali governments, pledged to work together to tackle sexual violence. The issue will also be on the agenda at the G8 leaders’ summit to be hosted by the United Kingdom in June.

But it will take time and money to bring about change in a country that has so many pressing needs.

Matt Baugh, UK ambassador to Somalia, told CNN that there were “no guarantees,” but the involvement of international partners should improve the chances of Somalia living up to its commitments on sexual violence.

“What needs to happen practically (is) to redress the balance, to turn this from a stigma of shame where the survivors, the victims of these horrible attacks, bear that burden, to one where it’s the perpetrators who feel ashamed about it,” he said.

There is now a realization, he said, of the “huge, huge problem facing the country as a whole, as well as women and girls,” but it will take time to make the necessary changes to tackle sexual violence.

These include better documentation of such crimes; reforming the security sector, so that the army and police come under greater government control and win people’s confidence; and reforming the judiciary so that ordinary Somali families believe in the justice system, he said.

“We’ve got the opportunity for the first time in 20 years, based on Somali leadership and their compelling vision, to chart a way forward,” he added.

“I think that this newfound stability and these new steps that have been made by Somalia, that the entire world is celebrating, because it is, indeed, worth celebrating, … has to be something that everybody has access to,” said Elman, in Mogadishu.

“We need to make sure that women are in this human space where we are moving forward.”

For the moment, though, Somalia’s women are relying on themselves — and each other — to rebuild their lives as best they can.

Protests over Berlin Barbie house

May 16th, 2013 No comments


Barbie The Dreamhouse Experience opens in Berlin, May 16.

(CNN) — Guess it’s a cultural thing.

While a Barbie-themed restaurant opening was hailed with general delight and fanfare in Taipei earlier this year, the opening of the blonde doll’s new European digs is being met with quite a different reception in Germany.

Left-wing feminists are protesting the Barbie Dreamhouse Experience — a 27,000-square-foot lifesized pink estate — opening in Berlin on May 16.

Located off the shopping district of Alexanderplatz, the Berlin Dreamhouse is meant to show off Barbie’s Malibu lifestyle.

The pink mansion is full of rooms showcasing how her makeup, kitchen and wardrobe are put together.

Barbie's pink digs display her extensive wardrobe and an apparent shopping addiction.

In addition to viewing 350 Barbie dolls and other displays, visitors can strut a long runway, “bake” virtual cupcakes in a pink kitchen or eat real ones in the cafe. And, of course, shell out for dolls and products in the gift shop.

Protestors from the Left Party are up in arms over the sexism and shallow materialism that they argue Barbie symbolizes.

“They present an image of cooking, primping and singing, as if it were in some way life-fulfilling,” Socialist Alternative editor Michael Koschitzki, 27, told German newspaper Der Spiegel.

“The Barbie Dreamhouse is the expression of a conventional role model that isn’t OK,” he said.

Barbie has long been a subject of controversy — with criticisms ranging from sexism to racism to creating body image issues for girls.

The Berlin movement has led to an “Occupy Barbie Dreamhouse” page on Facebook, which displays a cover image of a dark-haired girl saying, “I can’t stand pink!” in German. The page currently has 1,761 likes and is updated every few hours.

The group behind the Facebook page has also announced it’s planning a peaceful protest for opening day.

The Berlin mansion is Barbie’s first Dreamhouse in Europe and will be dismantled to tour other European cities after August 25.

A U.S. Dreamhouse opened last week in a Florida shopping mall, to mixed reviews.

Barbie the Dreamhouse Experience, Voltairestraße 2a/Dircksenstraße, Berlin; +49 30 4799 7433; May 16-August 25, 2013; open 10 a.m.-8 p.m. daily; admission €15 for adults, €12 for children under 14

(CNN) — Anyone that bikes dreams of riding a Tron Light Cycle. Revolights, a set of wheel-mounted LEDs, now makes that dream a little closer to reality, and a new built-in version is helping that system become even more lightweight and simple than the original bolt-on setup.

The white-and-red lighting comprises a ring of LEDs that you install around the entire edge of each of your bike rims. Using a pair of clever devices, only the forward-facing lights (or backwards, in the case of the rear wheel) illuminate when the wheel spins. The result is beautiful arcs of light that make you visible from all angles, an effect that Revolights’ co-founder and CFO Adam Pettler says came by accident.

Revolights inventor Kent Frankovich didn’t set out to produce the arcs, instead he was looking for a better headlight design, one that would make obstacles stand out more clearly though low angle lighting. The timed blinking of the lights was to prevent them from shining in a rider’s eyes. “It wasn’t until after he had created the first prototype that we realized the huge increase in rider visibility that came with it,” Pettler says, “He then quickly made a red taillight to match.”

The lights use two mechanisms to tell the LEDs when to turn on and off. At low speeds, an accelerometer determines the position of the lights by reading the pull of gravity. At higher velocities, the lights switch over to calculating speed based on the wheel’s period of rotation. That allows the system to synchronize a cascading LED pattern.

This is Revolights’ second Kickstarter campaign. The first one was completed in 2011, raising five times its initial goal. Pettler says this second Kickstarter is being done to celebrate the release of a v2 version of the product. Interestingly, the revamped Revolights City v2.0 kits aren’t one of the Kickstarter rewards.

“The City represents our second product, designed with the goal of making Revolights more accessible,” says Pettler. “And while it is a new product we now offer, Revolights City is an aftermarket kit you install on your own wheels, and we felt putting it on Kickstarter would be too similar to our last campaign.”

So they went bigger. The current Kickstarter is for custom wheels with the lights built right in. It’s a project created in partnership with Mission Bicycle Company (also a Kickstarter alum).

“We designed Revolights Wheels to address our largest design challenges: installation and compatibility,” says Pettler. “While many cyclists enjoy their existing wheels and want to put Revolights on them, there’s a whole other group of riders out there that don’t want to install their own lights.”

It’s a smart way of using Kickstarter. For simple product updates, there’s no need (and indeed some discouragement) for using Kickstarter. But by putting together an ambitious product for the crowd funding site and timing that to coincide with an update of your more stable product, you get the best of both worlds as a creator.

(CNN) — Photon torpedoes and proton torpedoes. Warp speed and hyperspace.

Shhh! Don’t tell anyone, but the “Star Trek” and “Star Wars” universes have quite a bit in common.

Still, there are also enough differences that the eternal franchise versus franchise debate still tends to unfold with all the fireworks of a big-budget action sequence.

How sea slugs helped win Nobel Prize

May 14th, 2013 No comments

(CNN) — Neuroscientists love Aplysia. They are a type of sea slug that grows to be about a foot long. With only 20,000 nerve cells — compared with about 100 billion found in the human brain — Aplysia are the perfect lab animals for brain researchers hoping to isolate a crucial connection.

Plus, “they’re just attractive to look at,” says Dr. Eric Kandel, a biochemistry and biophysics professor at Columbia University.

Kandel won the 2000 Nobel Prize in Physiology or Medicine for his work with Aplysia — or more specifically, for his work on the biological mechanisms of memory storage.

For decades, Kandel has studied how we create short-term and long-term memories at the molecular level. His work has shown what genes are changed during the learning process, how these genes are altered and how the changes contribute to the growth of new connections in the brain.

CNN spoke with Kandel about his research and why he’s fascinated by the human brain. The following interview has been edited for brevity and clarity:

CNN: Why do you think the Nobel Prize committee recognized your work?

Dr. Eric Kandel: There are two forms (of memory). One is complex forms of memory, which require the hippocampus and (are called) explicit memory storage. The very simple forms like driving a car — once you know how to do it, you do it automatically — we call that implicit memory storage. And the two involve different systems in the brain.

Being a romantic, I started out with Alden Spencer to study the hippocampus. I’m thinking, ‘That’s the seat of complex memory, and I want to get complicated.’ And we succeeded to record from the hippocampus. We were the first scientists to do this and we were euphoric.

A medical miracle: Saving cholera victims

But after a while, we realized that studying the cells in a region involved in memory is necessary but not sufficient. You’ve got to see how a memory is formed. You’ve got to see how information comes into the hippocampus and how it is stored over the long term. And when we tried to see what comes into the hippocampus, we found it very complicated to analyze. So I realized we had to take a very different approach.

Rather than studying the most complex form of memory in a very complicated animal, we had to take the most simple form — an implicit form of memory — in a very simple animal. So I began to look around for very simple animals. And I focused in on the marine snail Aplysia.

My colleagues and I found that learning involves alterations in the strength of communication between nerve cells.

Nerve cells communicate with one another at specialized points called synapses. And these synapses are plastic — they can be modified by learning. If you produce a short-term memory — if you look up a telephone number you just remember for a short period of time (or) you meet somebody and remember their name briefly — you have a transient change in the strength of communication. But if you have a long-term memory, you alter the expression of genes in the brain and you grow new synaptic connections.

So as I tell my friends, if you remember anything about this conversation, you will have a different brain than you started out with before the conversation.

CNN: So would memory work the same in a human as it does in a snail? In other words, is what you’ve discovered applicable to us?

Kandel: Yes and no. Obviously human memory is much more complicated than memory of a snail. We can learn things that they can’t learn, obviously. We (have) conscious experiences as well as unconscious experiences. So the level of complexity is infinitely greater.

But the remarkable thing that Darwin discovered is that evolution is very conservative. If it finds through natural selection that some set of mechanisms work, it tends to retain those mechanisms in perpetuity. And this is what one finds with the learning process.

10 women who changed medicine

CNN: What led you to neuroscience research?

Kandel: I had no interest in science whatsoever. I went to medical school after having decided to do so somewhere between my junior and senior year at Harvard — very late. I initially wanted to be an intellectual historian.

And I didn’t particularly enjoy the science courses; even in medical school, I enjoyed the clinical work much more than the basic science courses. But I found working in the lab is so completely different than reading a textbook about it. You know, you’re planning strategies; you’re working with your own hands. There’s essential satisfaction in running experiments.

I remember having dinner with my wife before we were married and telling her, ‘You know, I can see doing this for the rest of my life, but it’s ridiculous. You don’t have any money and I don’t have any money. We want to raise a family, and I’ve got to earn a living going into private practice.’ And she goes, ‘Money is of no significance.’

She has never uttered those magic words again, I can assure you (laughs). But that, at the moment, was quite inspirational.

CNN: Why has memory research held your attention for so long?

Kandel: Well, I think it’s a fascinating problem because it’s so central to everything we do.

I once had the privilege of going to a Willem de Kooning retrospective at MOMA (the Museum of Modern Art in New York). De Kooning already had Alzheimer’s disease. With Alzheimer’s disease, you lose explicit memory, complicated memory, so he would have difficulty recognizing people. But he would go into studio, and he’d be another person because for a gifted painter, painting is like an implicit skill. It’s like driving a car — after you learn it, you can do it automatically. And he did some beautiful paintings when he had fairly advanced Alzheimer’s disease.

Clive Wearing — the choir conductor in England — had a severe explicit memory deficit. He couldn’t recognize people, places. But when he sat down at the piano, he could play almost as well as he ever did. If you ask him afterward, ‘What’s it like to play the piano?’ He would say, ‘What are you talking about? I haven’t played the piano in 20 years.’

It’s amazing.

The other reason memory is so important is there is a number of a diseases that affect memory storage, and we’d like to know how they work so we can try to remedy them.

Mom’s death inspires doctor’s work

CNN: There’s been a lot of talk lately about “mapping” the brain. Why is that important?

Kandel: The brain is the most complex object in the universe. And it is so important that we understand it, not only to understand ourselves and who we are, but also to be able to overcome many of the miseries that affect the brain.

It’s not just schizophrenia and depression and post-traumatic stress disorder and anxiety syndromes and autism. It’s Huntington’s disease and Parkinson’s disease and Alzheimer’s disease — dreadful disorders that we want to be able to help people with. So this is a major challenge.

To see the president of the United States announce this first, in his State of the Union address, and then more recently at the White House — and I had the privilege of being there — is very exciting. They introduced President Obama by saying, this is our scientist in chief, and Obama broadly took on that title. So I think it’s wonderful.

CNN: In 2004, you said that we could have effective memory drugs in two years. Why do you think that’s proved to be a bit more difficult than expected?

Kandel: We have a reasonably good understanding of the molecular underpinnings of age-related memory loss. With Alzheimer’s disease, I think the understanding is surprisingly good. But if we’re so smart, how come we’re not rich? How come we don’t have treatments for Alzheimer’s disease?

There are two possibilities — one is that we’re deceiving ourselves and our understanding is much less complete than we think it is. Or, and I think this is a real possibility, we are starting to treat people too late in the disorder.

By the time they come to us with symptoms of Alzheimer’s disease, they’ve had the disease for 10 years. Now if, God forbid, somebody has breast cancer or colon cancer for 10 years and you sought treatment then, that’s pretty darn late if they’re (even) still alive at that particular point with this severe form of cancer. So the whole thrust in Alzheimer’s disease — or at least an important thrust — is to try to get early diagnoses so we can treat people much earlier than we are now treating them.

CNN: When you first began your research, did you think we’d get this far?

Kandel: Well, you know, it’s a relative thing. When I started, we knew, on the level that I now work, practically nothing. We knew the anatomy a bit, we knew a lot from clinical insights, but we had very little insight into the underlying mechanism. And we’ve made a lot of progress on that, not just in learning but in perception and motor coordination and development.

But if you look at where we want to go, what we ultimately want to understand, and how large the task is, one has to be very modest. … There’s much, much more to be studied, and much, much more to be learned.

Moreover, the clinical benefits that we’ve gained out of what we’ve learned so far have been modest. The best is yet to come.

Time travel: Can it really be done?

May 14th, 2013 No comments


The Sombrero Galaxy is thought to house a black hole, a gravitational field Davies says could lead to the future, but not the past.

Editor’s note: Paul Davies is author of “How to Build a Time Machine.” He works at Arizona State University.

(CNN) — Ever since H. G. Wells’ trailblazing novel “The Time Machine,” time travel has been a staple of science fiction. The idea of traveling through time is deeply fascinating: you get into a machine, press a few buttons, and step out not just somewhere else, but “somewhen” else. It’s easy to imagine, but can it really be done?

Yes it can, at least in a limited sense. Over a century ago, Albert Einstein showed that time is intrinsically elastic, capable of being stretched or shrunk by motion. Fly from London to New York and back, and you will leap a split second into the future of stay-at-home Londoners. The effect can easily be measured using atomic clocks and involves only billionths of a second — too brief for a person to notice, and hardly the stuff of “Doctor Who” television series-style adventures.

Paul Davies

But time stretching can be magnified by increasing the speed. Close to the speed of light (about 300,000 kilometers per second), time warps become startling. Fly to the star Vega, 25 light years away, and back again at 99% of the speed of light, and when you return to Earth in 2062, you will have experienced only seven years travel time in the spacecraft. In effect, you will have leaped 42 years into Earth’s future.

So travel into the future is not only possible, we have done it, although so far in only paltry amounts. How about going back in time? That is far more problematic and remains an active area of research. Einstein found that not only speed affects time, gravity does too. Time runs a little bit faster on the roof, where gravity is imperceptibly weaker, than in the basement, for example.

A really big time warp requires an intense gravitational field. Black holes are the best; near their surfaces time is slowed almost to a standstill relative to us. Indeed, black holes are black because outgoing light is trapped in slow motion. However, hanging out near a black hole is not only dangerous, it still only represents travel into the future; it gets you to the future quicker. Getting to the past requires something even weirder than a black hole — a wormhole.


The mystery of black holes


Faster than the speed of light?


Black hole hunting satellite launched

Read more: The great time travel debate

Wormholes in space are shortcuts linking distant points — a bit like that other sci-fi favorite, the star gate. Leap through one and you might come out on the other side of the galaxy a few minutes later. If wormholes exist, they could be adapted to make time machines that send you into the future if you traverse them in one direction, but into the past if you go in the other direction. Like a black hole, a wormhole would be a massive gravitational space and time warping object. But whereas a black hole represents a one-way journey to nowhere — jump in and you can never get out — a wormhole has an exit as well as an entrance.

Do wormholes exist? Black holes certainly do, but nobody has yet glimpsed any sign of its cousin, the wormhole. Furthermore, some physicists are so uneasy about their potential for being portals to the past that they flat-out reject the very idea. The problem concerns those familiar time travel paradoxes, like going back in time and murdering your mother before you were born. Physicists call these causal loop paradoxes, and they affront our desire for the universe to be a rational and ordered system. If cause and effect get muddled up in time, what does that do for our notions of reality?

Read more: ‘Looper’s’ potential for real world time travel

In spite of these misgivings, there is nothing in Einstein’s theory of space, time and gravitation to forbid journeying into the past, a possibility that Einstein himself hated. Not only wormholes, but several other mechanisms have been found that, according to Einstein’s theory, can be used to travel back in time. All these proposals suffer from the problem of extreme impracticality, though. Building a human-sized wormhole, for example, would require harnessing vast amounts of peculiar quantum field energy and deploying gravitational stabilizing technology that would need the resources of a cosmic super-civilization.

For many scientists, however, it is the principle that counts, not the practical engineering. And here there is an intriguing possibility. Few physicists think Einstein had the last word on gravitation, and some modern extensions of his work make an extraordinary prediction. The Large Hadron Collider — the giant accelerating machine that created the Higgs boson — might just make a tiny wormhole for long enough that its time-bending effects could be glimpsed.

The opinions expressed in this commentary are soley those of Paul Davies.
