एक आतंकी की पूरी कहानी...नरेंद्र मोदी के खून का प्‍यासा था हमजा



नई दिल्‍ली।

26/11 के मुंबई हमले के आरोपी सैयद जबीउद्दीन अंसारी उर्फ अबु हमजा के छिपने और उसकी गिरफ्तारी की कहानी जितनी दिलचस्‍प है, उसके इरादे उतने ही खौफनाक। दिल्‍ली पुलिस ने 25 जुलाई को उसकी गिरफ्तारी की बात सार्वजनिक की। लेकिन कहा जा रहा है कि उसे कुछ दिन पहले ही गिरफ्तार कर लिया गया था और डीएनए टेस्‍ट कराने के बाद इस बारे में ऐलान किया गया। डीएनए टेस्‍ट उसकी पहचान पुख्‍ता करने के लिए जरूरी था।

बताया जाता है कि अंसारी ने 26 नाम रख रखे थे। वह सऊदी अरब में रह रहा था और वहां से लौटने पर 21 जून को दिल्‍ली के इंदिरा गांधी अंतरराष्‍ट्रीय हवाई अड्डे पर गिरफ्तार कर लिया गया।


ऐसी खबरें आ रही हैं कि मुंबई हमले में सक्रिय भूमिका निभाने के बाद वह इस तरह का एक और हमला अंजाम देना चाहता था। उसके निशाने पर नरेंद्र मोदी भी थे। दरअसल, वह चर्चा में ही तभी आया था जब उसने मोदी की हत्‍या की साजिश रची थी।

Dopamine also regulates your sleep, scientists say

Washington <><><><

 Dopamine, or the feel-good brain chemical, has been linked to everything from laziness to creativity and from impulsivity to drug addiction.

Now, a new study has added sleep regulation to that list. Researchers at the University of Barcelona in Spain found that when dopamine latches onto its receptor in a special part of the brain, it seems to signal the body to "wake up" by turning down levels of the sleepiness hormone melatonin.

The first clue to this new discovery came when researchers noticed that dopamine receptor four, a protein on the outside of certain cells that binds to dopamine, was active in the part of the brain called pineal gland which regulates our internal clock, or the circadian rhythm, by releasing melatonin in response to light.

Interestingly, presence of the dopamine receptor on pineal gland cells seemed to cycle with the time of the day — the receptor numbers were high at night and lower during the day.

The researchers therefore thought this protein may be important in the circadian rhythm — your body's daily cycle of proteins that regulate daily patterns of feeding, sleeping, body temperature and other functions, LiveScience reported.

During the night, they found, the pineal gland produces a hormone called melatonin that makes you sleepy.

By studying human cells and rat pineal glands in the lab, the researchers have now found that the dopamine D4 receptor hooks up on the outside of pineal gland cells alongside norepinephrine receptors to dampen this melatonin-secretion signal in the early morning.

And while the norepinephrine complex turns up melatonin, along with your sleepiness, when dopamine and its receptor come into the picture, it forms a complex of proteins that does the opposite, said the researchers who detailed their study in the journal PLoS Biology.

When dopamine interacts with its receptor on the outside of the pineal cells, it interferes with the signal sent into the cell, leading to low production and release of melatonin.

Luckily, dopamine's light-dark cycle means the two (dopamine receptor and the norepinephrine's receptor, called the andrenergic receptor only hook up at the end of the night.

"The system is expressed in the evening. The dopamine receptor level peaks and you get this nice inhibition of the adrenergic receptor," study researcher Peter McCormick said.

"Everything is sort of on a delay so that by morning time or sunrise you get a complete inhibition of melatonin
production."

Studying how these two receptors work together in more depth could give researchers a better understanding of circadian rhythm and its associated disorders, like jet lag, the researchers noted.


It could also be relevant to sleep and mood disorders, such as depression, which involves not only odd dopamine levels in the brain, but also disturbed sleep patterns, they added.

Washington wants Pak out, India in as Afghanistan mentor


New York: Washington wants India to fill up the post-US vacuum in Afghanistan and play a bigger role training Afghan security forces as a NATO deadline to withdraw all its combat troops from that country by the end of 2014 draws near.
There is irony in the situation as the same US administration wanted India to downsize its footprint in Afghanistan till a couple of years ago for fear of offending Pakistan. Now US criticism of Pakistan is no longer hush- hush. In fact, the mood on Capitol Hill is so rabidly anti-Pakistan that a US Senator held up a Farm Bill in the Senate last week by wanting to tack on a bill to choke aid to Islamabad.
Tired of catering to Pakistan’s sulks about an Indian presence in Afganistan, the US is increasingly looking to India as a partner in developing Afghanistan. New Delhi has provided some $2 billion in assistance  to Afghanistan since 2001. Both the US and India have strategic partnership agreements with Afghanistan. At the cost of sending Pakistan into a paroxysms of rage, US Secretary Hillary Clinton proposed a trilateral engagement between the US, India and Afghanistan.xternal Affairs Minister SM Krishna said, alongside Clinton.

Nirupama Rao, India’s ambassador to Washington, made clear this month that India has every intention of preventing “a regression in Afghanistan to the situation it was before 2001.” However, India has sought reassurance that the US and its allies will retain a substantial presence in Afghanistan beyond 2014 because of concerns that a resurgent Taliban and al-Qaeda might allow Afghanistan to become a haven for Islamic jihadists obsessed with Kashmir.
“Any perception of lack of will on the part of the international community to deal firmly with terrorist groups will risk Afghanistan sliding back to being a safe haven for terrorist and extremist groups that threaten the region and beyond,” External Affairs Minister SM Krishna said, alongside Clinton as India and the US held their annual strategic dialogue in Washington.
Krishna also stressed the necessity to deal with “terrorist sanctuaries and safe havens” beyond Afghanistan’s borders in a veiled reference to Pakistan. The two governments also discussed terrorist safe havens in Pakistan.
Greater cooperation in counter-terrorism also populated the jammed agenda for the strategic talks. The US State Department, through its anti-terrorism assistance programmes, conducted eight courses in India in 2011 and will provide 14 courses in 2012 on topics ranging from bomb blast investigation, critical incident management, to cyber investigations and forensics.
“It’s not enough just to talk about cooperation on issues ranging from civil nuclear energy, attracting US investment to India or defending human rights or promoting women’s empowerment,” said Clinton.
“We have to follow through so that our people, citizens of two, great pluralistic democracies, can see and feel the benefits,” she added.
A day after listening to US industry leaders vent their frustration at the Indian government’s inability to pull off big ticket reforms, Krishna said he was “conscious of the fact that there is a degree of skepticism about the economic content” of the US-India relationship. He promised foreign investors a level playing field and transparency.
He said US companies will be able to participate in plans to invest more than $1 trillion on India’s infrastructure build-out in the next five years.
Two-way trade and investment has grown 40 percent since 2009 and is set to exceed $100 billion this year, but Clinton pointed out that there is “a lot of room for further growth.”
The two sides agreed Wednesday to expedite negotiations on a bilateral investment treaty.
