Is 'Immortal' jellyfish key to eternal life?






For many beach-goers, jellyfish are a nuisance that blights the sea shore. But some scientists believes they could hold the key to immorality. For many beach-goers, jellyfish are a nuisance that blights the sea shore. But some scientists believes they could hold the key to immorality.

  • Japanese scarlet jellyfish is known as the "immortal jellyfish"

  • Professor Shin Kubota is a marine expert from Japan researching its life cycle

  • He says the jellyfish could be the key to rejuvenation in humans




The Art of Movement is a monthly show that highlights the most significant innovations in science and technology that are helping shape our modern world.


(CNN) -- For centuries, man has been on a quest to find the elixir to eternal life. Alchemists struggled fruitlessly to create the legendary philosopher's stone -- a mythical substance capable of turning base metals into precious gold, and said to hold the key to immortality.


But perhaps they were going about it the wrong way. Instead of searching for answers on land, maybe they should have been looking to the sea.





The magic of bioluminescence




World's jellyfish population booming




Thousands of blue creatures wash ashore

In the seaside town of Shirahama, in Japan, one man thinks he knows what holds the key to everlasting life -- jellyfish.


Shin Kubota is a professor at Kyoto University's Seto Marine Biological Laboratory. He began studying the gelatinous sea creatures in 1979 but there's one type with which he's particularly preoccupied -- the scarlet jellyfish.


"They don't die," Kubota says, "they rejuvenate." He adds that they are one of three jellyfish species in japan that are considered "immortal."


"One day in my plankton net there was a small scarlet jellyfish from [the] south, which had many sharp sticks stuck into its body," he recalls. "I thought 'poor thing,' and removed all of the sticks, hoping it may become better and swim again. But it didn't and shrunk. However, it rejuvenated!"

It's less immortality and more regeneration but Kubota believes these tiny marine animals could hold the secret to perpetual life.


When an adult scarlet jellyfish -- or medusa -- is injured it goes to the bottom of the ocean floor. From there it morphs back into its infant state, known as a polyp. Then the polyp becomes a brand new medusa, allowing the Jellyfish to move between an adult and infant state in about two months.


So far, Kubota has succeeded in making one jellyfish rejuvenate an incredible 12 times in the lab. But there remain many unanswered questions.


"There should be a key to rejuvenation in the system of scarlet jellyfish," says Kubota. "I'd like to believe it could be applied to human beings because genetically jellyfish and humans are not so different."

Report: 1,400 sex abuse cases in 1 town





  • Abuses included gang rape, trafficking, beating, threats at gunpoint

  • Victims were as young as 11 years old, the report says

  • Social counselors, police, officials turned a blind eye, report says

  • Most suspects were ethnic minorities, and authorities were afraid of being branded racists




(CNN) -- Hundreds of children have been systematically raped, beaten and sex trafficked in a northern English town for more than 12 years. And it is still going on, a government commissioned report says.


The "appalling" revelations also expose cultural tensions and lack of communication between authorities and the town's ethnic minorities that may have helped stop it.


Social counselors saw evidence of sexual exploitation early on, but turned a blind eye, according to the Independent Inquiry into Child Sexual Exploitation in Rotherham.


The city's government recently made the inquiry's report available on its website.


And so the abuses amassed, which included gang rape and death threats at gunpoint.


At least 1,400 cases of abuse went on between 1997 and 2013 -- a conservative estimate, the report says. This year, specialist investigators are handling 51 cases. Other teams are looking at additional cases.


Torturous sexual abuse


The exploitation has reached a level tantamount to torture, according to the report.


"There were examples of children who had been doused in petrol and threatened with being set alight, threatened with guns, made to witness brutally violent rapes and threatened they would be next if they told anyone," the report says.


Some victims were not even in their teens.


"Girls as young as 11 were raped by large numbers of male perpetrators," the inquiry says.


The report accuses politicians, social services and police of "blatant" failure to stop them, citing an inability to traverse cultural barriers with Rotherham's small Muslim community.


Fear of label of racism


The perpetrators often worked together and were mostly of Pakistani heritage; the victims were mostly white girls, the report says.


An earlier report said that "Asian" gangs originally were exploiting women and girls "for their personal gratification" but later turned to making money with it, passing girls around.


Social counselors often took a hands-off approach to the cases for fear of being branded as racists or stoking a right-wing backlash in the city.


"Several (counselors) interviewed believed that by opening up these issues they could be 'giving oxygen' to racist perspectives that might in turn attract extremist political groups and threaten community cohesion. To some extent this concern was valid, with the apparent targeting of the town by groups such as the English Defence League," the report says.


Though known victims were mostly white, the report delved into an underbelly of alleged systematic abuse by select groups of Asian men against women in their own ethnic groups.


These often go unreported, because the victims fear vengeance or public shame in their communities, the report says. Perpetrators may be using that fear to blackmail these victims into continued sexual servitude.


Community left out


Cultural differences also hindered effective involvement with concerned members of Rotherham's Pakistani community.


Authorities turned to male community leaders and imams and greatly left out women. Many ethnic Pakistani women told the Inquiry that it made them feel disenfranchised and prevented people from speaking openly about abuse.


Members of both genders said they missed any direct engagement on the topic by officials. "This needed to be addressed urgently, rather than 'tiptoeing' around the issue," the report said.


Under the rug


Some social counselors also hoped cases they were seeing were one-off occurrences and hoped they would go away. That may have been bolstered by the fact that the vast majority of child sexual abusers in Britain are white males.


Research reports on the problem began appearing a few years ago, but they had little effect.


"The first of these reports was effectively suppressed, because some senior officers disbelieved the data it contained," the report said.


Social services managers downplayed the problem. Officials thought reports were exaggerated. Law enforcement gave it little importance.


"Police gave no priority to (child sexual abuse), regarding many child victims with contempt and failing to act on their abuse as a crime," the report said.


Improvement but frustration


By the time awareness of the problem increased by 2009, thinly staffed social service workers were overwhelmed by the number of potential victims.


There has been a marked improvement in training police to recognize sexual abuse and work together with social services, the inquiry says.


"But the team struggles to keep pace with the demands of its workload," according to the report. And finances are running low.


And still, few cases even make it to court.



Ebola outbreak is accelerating





  • World Health Organization says West Africa Ebola outbreak continues to accelerate

  • There are 1,552 confirmed deaths from the Ebola virus, WHO says

  • New "road map" aims to curb outbreak in six to nine months, stop international spread

  • Road map acknowledges that the eventual death toll in this outbreak could exceed 20,000




(CNN) -- The Ebola outbreak "continues to accelerate" in West Africa and has killed 1,552 people, the World Health Organization said Thursday.


The total number of cases stands at 3,069, with 40% occurring in the past three weeks. "However, most cases are concentrated in only a few localities," the WHO said.


The outbreak, the deadliest ever, has been centered in Guinea, Sierra Leone and Liberia, with a handful of cases in Nigeria. The overall fatality rate is 52%, the WHO said, ranging from 42% in Sierra Leone to 66% in Guinea.


The WHO issued a "road map" Thursday that "responds to the urgent need to dramatically scale up the international response" in light of the acceleration of new cases, it said.

How an Ebola outbreak can start, and end




CDC: Worker possibly exposed to Ebola

It aims to stop Ebola transmission in affected countries within six to nine months and prevent its spread internationally.


The road map prioritizes the setting up of treatment centers, community mobilization and safe burials.


It will also try to overcome bottlenecks in vital supplies such as personal protective equipment, disinfectants and body bags.


The road map is based on an assumption that "in many areas of intense transmission the actual number of cases may be 2-4 fold higher than that currently reported," the document states.


It also acknowledges that the total number of cases "could exceed 20,000 over the course of this emergency."


But such a plan is easier stated than carried out, said the aid group Doctors Without Borders, also known as Medecins Sans Frontieres.


The road map should not give a false sense of hope, the group's director of operations, Brice de le Vingne, said in a statement.


"A plan needs to be acted upon," he said. "Huge questions remain about who will implement the elements in the plan."


All of the best medical aid organizations have not had the proper setup to respond at the scale needed to seriously make a dent in the Ebola outbreak, he said.


"As an international public health emergency, states with the capacity to help have the responsibility to mobilize resources to the affected countries, rather than watching from the sidelines with a naive hope that the situation will improve," he said.


Vaccine trials accelerated


An Ebola vaccine being developed by the U.S. National Institutes of Health and GlaxoSmithKline will be fast-tracked for human trials, the international consortium behind the effort said Thursday.


The experimental vaccine could be given to healthy volunteers in Britain, Gambia and Mali as early as September, according to a statement from the consortium, which provided funding.


The vaccine, which does not contain infectious virus material, has showed promise in early tests on primates to protect them from Ebola without significant adverse effects, the statement said.


The human trials will begin as soon as ethical and regulatory approvals are granted.


Nine things to know about the killer disease


'Worse than I'd feared'


Health workers are paying a heavy price as they care for those struck down by the virus.





Are we closer to stopping Ebola?




American leads Ebola treatment center

The WHO said Monday that 120 health care workers have died in the Ebola outbreak, and twice that number have been infected.


Public health experts say several factors are to blame, including a shortage of protective gear and improper use of the gear the workers do have.


"It's even worse than I'd feared," Dr. Tom Frieden, director of the U.S. Centers for Disease Control and Prevention, said Wednesday of the crisis. "Every day this outbreak goes on, it increases the risk for another export to another country.


"The sooner the world comes together to help Liberia and West Africans, the safer we will all be."


Frieden spoke to CNN's Nima Elbagir in Monrovia, Liberia, where fear and anger over the largest Ebola outbreak on record has grown as health officials put up quarantines around some of the capital city's poorest areas.


A separate Ebola outbreak, unrelated to the one in West Africa, was reported Sunday by the Democratic Republic of Congo.


Are myths making the Ebola outbreak worse?
