K-4 मिसाइल का सीक्रेट टेस्ट ऐसा करने वाला दुनिया का 5th देश बना भारत

फिर पूरी दुनिया को चौंकाया भारत ने, उठाया बेहद ताकतवर कदम, चीन, अमेरिका, यहां तक कि रूस भी सतर्क

एक बड़ी कामयाबी हासिल करते हुए भारत ने परमाणु हथियारों को ले जाने में सक्षम के-4 मिसाइल को अरिहंत पनडुब्बी से लांच कर सफल परीक्षण किया। सबसे खास बात यह है कि के-4 मिसाइल और अरिहंत पनडुब्बी दोनों को स्वदेश में ही विकसित किया गया है। के-4 की रेंज 3,500 किलोमीटर है, साथ ही यह दो हजार किलोग्राम गोला-बारूद अपने साथ ले जाने में सक्षम है। बंगाल की खाड़ी में अज्ञात जगह से मिसाइल को लॉन्च किया गया।
के-4 मिसाइल का नाम पूर्व राष्ट्रपति एपीजे अब्दुल कलाम के नाम पर रखा गया है, जिसमें के-4 मिसाइल का कोड नेम है। मिसाइल की कामयाब लॉन्चिंग के साथ ही भारत पानी के भीतर मिसाइल दागने की ताकत रखने वाला दुनिया का पांचवां देश बन गया है। इससे पहले ये तकनीक अमेरिका, रूस, फ्रांस और चीन के ही पास थी। मिसाइल के सफल परीक्षण से भारत के परमाणु हथियार कार्यक्रम को और ज्यादा मजबूती मिलेगी। इसके साथ ही भारत ने जमीन, हवा और पानी के भीतर से लंबी दूरी की न्यूक्लियर मिसाइल दागने की क्षमता विकसित कर ली है। के-4 बैलेस्टिक मिसाइल को पानी के भीतर 20 फीट नीचे से भी दागा जा सकता है।
आइएनएस अरिहंत पनडुब्बी को एक बार में चार के-4 मिसाइल से लैस किया जा सकता है।  के-4 मिसाइल को डिफेंस रिसर्च एंड डेवलपमेंट ऑर्गनाइजेशन यानी डीआरडीओ ने विकसित किया है। अब डीआरडीओ के सीरीज की तीन और मिसाइलों को विकसित करने पर काम कर रहा है। अगले कुछ साल में सेना, एयरफोर्स और नेवी को के-4 की सेवाएं हासिल हो सकेंगी।
रक्षा विशेषज्ञों का मानना है कि के-4 मिसाइल, अग्नि-3  मिसाइल के मुकाबले कई गुना बेहतर है, क्योंकि परमाणु सक्षम मिसाइल अग्नि-3 इस पनडुब्बी के लिए मुफीद नहीं है, जबकि के-4 मिसाइल को खास तौर पर आईएनएस अरिहंत पनडुब्बी के लिए ही विकसित किया गया है। पूर्व नौसेना प्रमुख एडमिरल अरुण प्रकाश (सेवानिवृत्त) ने इसे एक बड़ा कदम करार दिया है, लेकिन उनके मुताबिक जल्द ही अरिहंत को 5000 किलोमीटर से ज्यादा रेंज की अंतर प्राद्वीपीय मिसाइल (इंटर बैलेस्टिक मिसाइल) से लैस करने की जरूरत है, ताकि यह पनडुब्बी भारतीय समुद्र के किसी भी हिस्से में अपने लक्ष्य के लिए खतरा साबित हो सके।
अंतर्राष्ट्रीय दबाव की वजह से के-4 के परीक्षण को पिछले दिनों गुप्त रूप से किया गया और रक्षा अनुसंधान व विकास संगठन (डीआरडीओ) ने आधिकारिक रूप से इस बारे में कोई टिप्पणी नहीं की है। फिलहाल यह परीक्षण पूरी तरह कामयाब रहा। दावा किया जा रहा है कि यह मिसाइल सिस्ट‍म बेहद खतरनाक है और दुनिया में अपने किस्म का पहला है।
मीडिया रिपोर्ट्स के अनुसार टेस्ट टू स्ट्रैटेजिक फोर्सेज कमांड और डीआरडीओ के अधिकारियों की देखरेख में यह परीक्षण पिछले दिनों बंगाल की खाड़ी में किया गया। मिसाइल को पानी के 20 मीटर नीचे से दागा गया। लक्ष्य को भेदने से पहले मिसाइल ने 700 किमी की दूरी तय की। यह मिसाइल 3500 किमी दूरी तक के लक्ष्य को भेद सकता है।
मीडिया रिपोर्ट्स के मुताबिक, एक टेस्ट आंध्र प्रदेश के विशाखापत्तनम तट से 45 नॉटिकल मील दूर समुद्र में किया गया। टेस्ट के दौरान डमी पेलोड का इस्तेमाल किया गया। विशेषज्ञों के अनुसार के-4 मिसाइल को अभी दो और तीन बार और ट्रायल से गुजरकर विकसित होना है ताकि इसे सेना में शामिल किया जा सके। इससे पहले, सात मार्च को इस मिसाइल का डमी टेस्ट फायर किया गया था।
बीते साल नवंबर में अरिहंत से के-15 मिसाइल के प्रोटोटाइप का भी कामयाब टेस्ट हुआ था। के-15 , के-4 का छोटा वर्जन ही है। बाद में इसका नाम बदलकर B-05 कर दिया गया। यह अब सेना में शामिल किए जाने के लिए तैयार है। डीआरडीओ अब के-5 मिसाइल वि‍कसित कर रहा है, इसकी रेंज 5000 किमी होगी, जिसमें चीन के भीतरी हिस्सों में अपने लक्ष्य को भेदने की क्षमता होगी।
पिछले दिनों ही भारत ने किसी भी बैलेस्टिक मिसाइल हमले को बीच में ही नाकाम करने में सक्षम इंटरसेप्टर मिसाइल का सफलतापूर्वक परीक्षण कर लिया था, अब सबमरीन के क्षेत्र में के-4 के सफल प्रक्षेपण से भारत की रक्षा पंक्ति मजबूत हो गई है, लेकिन अभी भी हमें इस पर बहुत सुधार करने की जरूरत है क्योंकि अमेरिका की सबसे ताजा न्यूक्लियर नोटबुक “बुलेटिन ऑफ दि एटोमिक साइंटिस्ट “की एक रिपोर्ट के अनुसार अगले एक दशक यानी 2015 तक पाकिस्तान दुनियां की पांचवी सबसे बड़ी परमाणु शक्ति होगा। 2025 तक पाकिस्तान के पास करीब 350 परमाणु हथियार हो जाएंगे, वर्तमान में पाकिस्तान के पास 120 जबकि भारत के पास भी लगभग 100 हैं। फिलहाल विश्व में सबसे ज्यादा परमाणु हथियार अमेरिका और रूस के पास है।
के-4 की ऑपरेशनल रेंज 3500 किमी, लंबाई-12 मीटर, चौड़ाई-1.3 मीटर, वजन-17 टन, ढोए जा सकने वाले आयुध का वजन 2000 किलोग्राम है।

Moderate coffee drinking may reduce death risk

Drinking two to three cups of coffee daily may reduce your risk of death from heart disease, diabetes and suicide, researchers including those of Indian-origin have claimed. 

In the study, people who regularly drank moderate amounts of coffee daily - less than 5 cups per day - experienced a lower risk of deaths from cardiovascular disease, neurological diseases, Type 2 diabetes and suicide. 
The benefit held true for drinking caffeinated and decaffeinated coffee, suggesting it is not just the caffeine providing health perks but possibly the naturally occurring chemical compounds in the coffee beans. 

"Bioactive compounds in coffee reduce insulin resistance and systematic inflammation," said Ming Ding, the study's first author and doctoral student at the Harvard TH Chan School of Public Health in Boston, Massachusetts. 

"They might be responsible for the inverse association between coffee and mortality. However, more studies are needed to investigate the biological mechanisms producing these effects," said Ding. 

The findings are based on data from three large ongoing studies: 74,890 women in the Nurses' Health Study; 93,054 women in the Nurses' Health Study 2; and 40,557 men in the Health Professionals Follow-up Study. 

Researchers assessed coffee drinking every four years using validated food questionnaires and followed participants for up to 30 years. During the follow-up period, 19,524 women and 12,432 men died from a range of causes. 

In general, people who frequently drank coffee were more likely to smoke and drink alcohol. To separate the effects of coffee from smoking, researchers repeated their analysis among never-smokers, and found that the protective benefits of coffee on deaths became even more evident. 

"Regular consumption of coffee can be included as part of a healthy, balanced diet," said senior author Frank Hu, a Professor of Nutrition and Epidemiology at Harvard. 

"However, certain populations such as pregnant women and children should be cautious about high caffeine intake from coffee or other beverages," said Hu. 

The study by researchers, including Ambika Satija and Shilpa N Bhupathiraju, both from Harvard, was not designed to show a direct cause and effect relationship between coffee consumption and dying from illness. So the findings should be interpreted with caution, researchers said. 

Previous studies found inconsistent associations between coffee drinking and risk of total and cause-specific death. The new study adds to the literature that moderate coffee consumption may confer health benefits.

TV soaps may kill your love life: Study

Know why your love life sucks? Blame it on those “family action-packed” TV serials your partner watches every evening.
According to a new study, love is an ingredient lacking in some of our favourite TV sitcoms and those who watch such shows have a more cynical view on love and romance.
People who watch sitcoms regularly tend to have less of a belief in the idea of soulmates and lasting love.
“But viewers who tune into reality shows, like dating ones, have a greater tendency to be romantic and believe in the idea of true love,” researchers from University of Michigan said.
The study looked to prove how influential, even subconsciously, TV can be on a person’s belief system.
“Sitcoms, unlike dating shows, paint a flawed view of love. Rarely do relationships last on such shows and when they do, they are far from perfect,” researchers added.
The study was published in the journal Psychology of Popular Media Culture.

Overweight dogs may die young

M_Id_427179_overweight_dogs_life_span Dog owners may want to keep their pooch's weight in check!
Being overweight shortens a dog's life expectancy, a new study has found.
Data on a range of popular dog breeds from across the US showed that dogs that are overweight in middle age have a shorter life expectancy than ideal weight dogs.
Specifically, overweight dogs were found to suffer a reduction in life expectancy of up to ten months compared to ideal weight dogs, researchers said.
Being overweight in middle age can have potentially far-reaching consequences for a dog's life span, highlighting the importance of maintaining dogs at a healthy body weight throughout life.
The research examined the impact of body condition score on the life expectancy of a broad range of popular breeds.
"We saw that overweight dogs tend to have a shorter life expectancy. This was particularly pronounced in five breeds - Labrador, Shih Tzu, American Cocker Spaniel, Golden Retriever and Beagle," said lead scientist Carina Salt, from WALTHAM Centre for Pet Nutrition.
"This is the first reported research of its kind looking specifically at a large number of pet dogs. The findings therefore provide important insights into the risks of being overweight for dogs in the general population," said Salt.
"Being overweight in middle age can have long-term consequences and, depending on breed, mean a reduction in life span of between one and ten months," Salt added.
The research used data on the body condition of male and female neutered dogs aged between 6.5 and 8.5 years from 10 popular breeds.
There were on average 546 dogs per breed and data were collected by veterinarians during consultations across the network of Banfield Pet Hospital locations in the US.
The findings were presented at the WALTHAM International Nutritional Sciences Symposium

NASA launches spacecraft to study Moon's atmosphere

roll_a3 NASA has launched an unmanned spacecraft from Virginia that aims at unlocking the mysteries of Moon's atmosphere, a first moonshot from the state in the history of space exploration.
The Lunar Atmosphere and Dust Environment Explorer or Ladee spacecraft, which is charged with studying the lunar atmosphere and dust, soared aboard an unmanned Minotaur rocket a little before midnight from from Wallops Island.
It was a change of venue for NASA, which normally launches moon missions from Cape Canaveral, Florida. But it provided a rare light show along the East Coast for those blessed with clear skies.
NASA expected the launch from Virginia's Eastern Shore to be visible, weather permitting, as far south as South Carolina, as far north as Maine and as far west as Pittsburgh. The Ladee is taking a roundabout path to the moon, making three huge laps around Earth before getting close enough to pop into lunar orbit.
Unlike the quick three-day Apollo flights to the moon, Ladee will need a full month to reach Earth's closest neighbour.
An Air Force Minotaur V rocket, built by Orbital Sciences Corp., provided the ride from NASA's Wallops Flight Facility. Ladee, which is the size of a small car, is expected to reach the moon on October 6.Scientists want to learn the composition of the Moon's ever-so-delicate atmosphere and how it might change over time. Another puzzle, dating back decades, is whether dust actually levitates from the lunar surface.
The USD 280 million moon-orbiting mission will last six months and end with a suicide plunge into the moon for Ladee. The 844-pound spacecraft has three science instruments as well as laser communication test equipment that could revolutionise data relay. NASA hopes to eventually replace its traditional radio systems with laser communications, which would mean faster bandwidth using significantly less power and smaller devices.
It was a momentous night for Wallops, which was making its first deep-space liftoff. All of its previous launches were confined to Earth orbit. NASA chose Wallops for Ladee because of the Minotaur V rocket, comprised of converted intercontinental ballistic missile motors belonging to the Air Force.
A US-Russian treaty limits the number of launch sites because of the missile parts. All but one of NASA's previous moon missions since 1959, including the manned Apollo flights of the late 1960s and early 1970s, originated from Cape Canaveral.
The most recent were the twin Grail spacecraft launched almost exactly two years ago. The military-NASA Clementine rocketed away from Southern California in 1994.
Wallops will be back in the spotlight in less than two weeks. The Virginia-based Orbital Sciences will make its first delivery to the International Space Station, using its own Antares rocket and Cygnus capsule. That commercial launch is scheduled for September 17.

Young women who drink alcohol at greater risk of breast cancer

T330_19814_alcohol The more alcohol a young woman drinks before motherhood, the greater her risk of future breast cancer, a new study has warned.
If a female averages a drink per day between her first period and her first full-term pregnancy, she increases her risk of breast cancer by 13 per cent, according to a new study from Washington University School of Medicine in St Louis.
This is the first study to link increased breast cancer risk to drinking between early adolescence and first full-term pregnancy.
Previous studies have looked at breast cancer risk and alcohol consumption later in life or at the effect of adolescent drinking on noncancerous breast disease.
"More and more heavy drinking is occurring on college campuses and during adolescence, and not enough people are considering future risk," said study co-author Graham Colditz, associate director for cancer prevention and control at Siteman Cancer Center at Barnes-Jewish Hospital and Washington University School of Medicine.
"But, according to our research, the lesson is clear: If a female averages a drink per day between her first period and her first full-term pregnancy, she increases her risk of breast cancer by 13 per cent," Colditz said.
The researchers also found that for every bottle of beer, glass of wine or shot of liquor consumed daily, a young woman increases her risk of proliferative benign breast disease by 15 per cent.
Although such lesions are noncancerous, their presence increases breast cancer risk by as much as 500 per cent, said first author of the study, Ying Liu, a School of Medicine instructor in the Division of Public Health Sciences.
The findings are based on a review of the health histories of 91,005 mothers enrolled in the Nurses' Health Study II from 1989 to 2009.
Researchers didn't consider the effects of adolescent and early adulthood drinking on women who didn't have a full-term pregnancy because not enough were represented among those studied, Liu said.
Breast tissue cells are particularly susceptible to cancer-causing substances as they undergo rapid proliferation during adolescence and later.
Adding to the risk is the lengthening time frame between the average age of a girl's first menstrual cycle and the average age of a woman's first full-term pregnancy.
"Reducing drinking to less than one drink per day, especially during this time period, is a key strategy to reducing lifetime risk of breast cancer," he said.
The study is published in the Journal of the National Cancer Institute.
