Mammoth fragments raise cloning hopes

Well-preserved frozen woolly mammoth fragments have been discovered deep in Siberia that may contain living cells, edging a tad closer to the possibility of cloning a prehistoric animal, the mission's organiser has said.

Russia's North-Eastern Federal University said an international team of researchers had discovered mammoth hair, soft tissues and bone marrow some 328 feet (100 meters) underground during a summer expedition in the northeastern province of Yakutia.

Expedition chief Semyon Grigoryev said Korean scientists with the team had set a goal of finding living cells in the hope of cloning a mammoth. Scientists have previously found bones and fragments but not living cells.

Mr Grigoryev told the online newspaper Vzglyad it would take months of research to determine whether they have indeed found the cells.

"Only after thorough laboratory research it will be known whether these are living cells or not," he said, adding that would take until the end of the year at the earliest.

Woolly mammoths are thought to have died out around 10,000 years ago, although scientists think small groups of them lived longer in Alaska and on Russia's Wrangel Island off the Siberian coast.

Scientists already have deciphered much of the genetic code of the woolly mammoth from balls of mammoth hair found frozen in the Siberian permafrost. Some believe it's possible to recreate the prehistoric animal if they find living cells in the permafrost.

Those who succeed in recreating an extinct animal could claim a "Jurassic Park prize," the concept of which is being developed by the X Prize Foundation that awarded a 2004 prize for the first private spacecraft.

WARNING FROM RAEL: For those who don't use their intelligence at its
full capacity, the label "selected by RAEL" on some articles does not
mean that I agree with their content or support it. "Selected by RAEL"
means that I believe it is important for the people of this planet to
know about what people think or do, even when what they think or do is
completely stupid and against our philosophy. When I selected articles
in the past about stupid Christian fundamentalists in America praying
for rain, I am sure no Rael-Science reader was stupid enough to believe
that I was supporting praying to change the weather. So, when I select
articles which are in favor of drugs, anti-Semitic, anti-Jewish, racist,
revisionist, or inciting hatred against any group or religion, or any
other stupid article, it does not mean that I support them. It just
means that it is important for all human beings to know about them.
Common sense, which is usually very good among our readers, is good
enough to understand that. When, like in the recent articles on drug
decriminalization, it is necessary to make it clearer, I add a comment,
which in this case was very clear: I support decriminalizing all drugs,
as it is stupid to throw depressed and sad people (as only depressed and
sad people use drugs) in prison and ruin their life with a criminal
record. That does not mean that there is any change to the Message which
says clearly that we must not use any drug except for medical purposes.
The same applies to the freedom of expression which must be absolute.
That does not mean again of course that I agree with anti-Jews,
anti-Semites, racists of any kind or anti-Raelians. But by knowing your
enemies or the enemies of your values, you are better equipped to fight
them. With love and respect of course, and with the wonderful sentence
of the French philosopher Voltaire in mind: "I disapprove of what you
say, but I will defend to the death your right to say it".

it is simply a succession of mistakes, intolerances and violations.
 
On the contrary, let us embrace Science and the new technologies
unfettered, for it is these which will liberate mankind from the
myth of god, and free us from our age old fears, from disease,
death and the sweat of labour.

SPRAY OF HOPE

Military developing anti-suicide nasal spray as deaths hit record numbers

As the suicide rate among soldiers climbs to the highest levels in history, the Army is hoping Americans might one day treat their mental health woes with a single sniff.

The Army has just handed a $3 million grant to researchers at the University of Indiana’s School of Medicine for the creation of an anti-suicide nasal spray. The project, to be led by Dr. Michael Kubek, an associate professor of neurobiology, is arguably one of the more unusual military efforts to thwart a record number of suicides among active-duty personnel and veterans.

“Suicide is the toughest enemy I have faced in my 37 years in the Army,” Gen. Lloyd J. Austin III, the Army’s vice chief of staff, said this week in announcing new suicide numbers. Austin is spearheading his service’s efforts to find ways to halt the surge in suicides.

“That said, I do believe suicide is preventable,” Austin added. “To combat it effectively will require sophisticated solutions aimed at helping individuals to build resiliency and strengthen their life coping skills.”

According to Kubek and his colleagues, a snort of their suicide-stopping neurochemical — a naturally occurring compound called thyrotropin-releasing hormone, or TRH — could be the solution.

Suicide among American troops has increased steadily since the start of the wars in Iraq and Afghanistan. In July, the number of suicides among active-duty soldiers reached 26 — more than double the number in June and the highest for any month since the Army began keeping such statistics.

The Pentagon reported in June that suicides among soldiers have averaged one per day this year, an 18 percent increase in suicides during the same period last year, and have now surpassed the rate of combat fatalities.

“We’ve known since the 1970s that TRH has antidepressant effects, and it works quite rapidly,” Kubek, whose work has been instrumental in uncovering how TRH impacts the brain, told The Daily. “The bottom-line problem has been figuring out how to get it into the brain.”

Earlier trials of TRH already showed that boosting an individual’s levels can quickly decrease suicidal ideas, depression and bipolar disorders. But doctors have until now relied on spinal taps to dose patients — because TRH can’t cross the blood-brain barrier by more traditional methods, like pills or injections.

By harnessing new advancements in nanotechnology, however, Kubek’s research team has now devised nanoparticle drug-delivery systems, designed to dissolve over time inside the brain, that can safely usher TRH across the blood-brain barrier when inserted into the human nasal cavity.

The nanoparticle breakthrough was enough to convince military brass that Kubek’s nasal spray just might have a shot at preventing suicides. The project’s three-year Army grant will be used to ascertain whether TRH and the drug-delivery systems are safe, and then conduct a clinical trial to “show, in human patients, that this really can save lives,” Kubek said.

And like a myriad of military medical breakthroughs before it, the spray might one day make it into the hands, and noses, of civilian patients. Already, the National Institute of Mental Health has funded research that used TRH to treat civilians suffering from bipolar disorder and depression. “This is far from a soldiers-only solution,” Kubek said. “Potentially, if this works, we have an entirely new type of pharmacology.”

Indeed, experts in the realm of civilian mental health said they’re heartened by the research. “This is a brilliant idea,” Dr. Ken Duckworth, medical director for the National Alliance on Mental Illness, told The Daily. “It would solve one of the biggest problems we have with medication used today. It might work, but it doesn’t work fast enough.”

Should the program succeed, TRH wouldn’t entirely replace traditional antidepressants. Instead, Kubek envisions using it as a rapid-fire prevention tactic among patients in crisis, or immediately after a patient starts taking antidepressants, such as Prozac or Zoloft, which typically take four to six weeks to kick in.

“The phase directly after starting an antidepressant is very vulnerable time frame in a patient’s life,” he said, adding that patients aged 18-24, like much of the military population, are most at-risk during this period. “The nasal spray would stabilize them right away, while they wait for the [antidepressants] to do their job.”

Nationwide, suicides are the 10th leading cause of death among adults, according to the Centers for Disease Control and Prevention, and rates continue to hold steady or increase across demographics. “As a public health concern, suicide is something we haven’t had success in addressing,” Duckworth said. “There is a crying need out there for something like this.”
