The number of nuclear weapons in
the world continue to decline, but at a slower pace than in previous
years, the Stockholm International Peace Research Institute (SIPRI) said
today. "Over the past five years there has been a steady decline in
the overall number of nuclear warheads in the world," the think tank
said in its yearly report on world nuclear forces. "The decrease is due
mainly to Russia and the US, which together still account for more than
93 per cent of all nuclear weapons." While the two main nuclear powers
keep reducing their arsenals, other nuclear states including Britain
and France remained stable in this year's report with 225 and 300
warheads, respectively. "China, India and Pakistan are the only nuclear
weapon states that are expanding their nuclear arsenals, while Israel
appears to be waiting to see how the situation in Iran develops," SIPRI
said. According to the report, China held 250 warheads, India between
90 and 110, Pakistan between 100 and 120 and Israel 80, at the beginning
of 2014. The number of nuclear warheads in the world has dropped by
930 from 2013 to 16,300 this year, whereas in 2011 the figure fell by
2,070 to 20,530 compared with a year earlier. The think tank warned
that the decline does not imply a real commitment by the nuclear powers
to give up their arsenals. The United States and Russia still held some
7,300 and 8,000 warheads respectively at the beginning of this year,
SIPRI said. "Once again this year, the nuclear weapon-possessing states
took little action to indicate a genuine willingness to work toward
complete dismantlement of their nuclear arsenals," SIPRI researchers
Shannon Kile and Phillip Patton Schell said in a statement. "The
long-term modernisation programmes under way in these states suggest
their views that nuclear weapons will remain deeply embedded elements of
their strategic calculus." North Korea appeared on the list with six
to eight warheards. "There is an emerging consensus in the expert
community that North Korea has produced a small number of nuclear
weapons, as distinct from rudimentary nuclear explosive devices," the
think tank said. However, SIPRI researcher Schell told AFP that these
figures were based on the amount of plutonium the country could have
produced and not on its ability to effectively use it as a weapon.
"There is possibly enough material for six to eight weapons," he said.
"But there's been no clear indication yet of their ability to produce a
nuclear warhead and to produce an associated missile system that could
carry this warhead."
Difficulty or inability to write a coherent text message, even in people who have no problem speaking, may become a "vital" tool in diagnosing a type of crippling stroke, according to a new research. Scientists at Henry Ford Hospital focused on a 40-year-old man visiting the metro Detroit area on business who showed signs of "dystextia," a recently coined term for incoherent text messaging that can sometimes be confused with autocorrect garble. But in his case, the man saw nothing wrong with the garble. The patient had no problem with a routine bedside test of his language abilities - including fluency of speech, reading, writing, comprehension and other factors. However, when asked to type a simple text message, he not only produced garble, but he was unable to see it as such. Despite showing only slight facial asymmetry and no other symptoms, doctors determined the man had suffered an acute ischemic stroke, in which a clot or other blockage cuts off blood supply t...
