New Delhi: Home to a slew of extremist groups and with as many as 120 warheads, Pakistan adds to the dangers it presents for South Asia and, indeed, the entire world, The New York Times editorial board opined on Sunday, urging the world powers to rein in its nuclear weapons program as an international priority.
“With as many as 120 warheads, Pakistan could in a decade become the world’s third-ranked nuclear power, behind the United States and Russia, but ahead of China, France and Britain. Its arsenal is growing faster than any other country’s, and it has become even more lethal in recent years with the addition of small tactical nuclear weapons that can hit India and longer-range nuclear missiles that can reach farther,” the NYT editorial said.
Stressing on “the fact that Pakistan is also home to a slew of extremist groups, some of which are backed by a paranoid security establishment obsessed with India,” the paper urged the world powers to rein in its nuclear weapons program as an international priority in view of the dangers it presents for South Asia and, indeed, the entire world.
“The major world powers spent two years negotiating an agreement to restrain the nuclear ambitions of Iran, which doesn’t have a single nuclear weapon. Yet there has been no comparable investment of effort in Pakistan, which, along with India, has so far refused to consider any limits at all.”
The paper expressed displeasure over the recent meeting at the White House on October 22 between President Obama and Prime Minister Nawaz Sharif of Pakistan that appeared to have gone nowhere.
“Yet it would be wrong not to keep trying, especially at a time of heightened tensions between Pakistan and India over Kashmir and terrorism.”
At the moment, Pakistan is a pariah in the nuclear sphere to all but China… Pakistan has done itself no favors by refusing to join the Nuclear Nonproliferation Treaty and by giving nuclear know-how to bad actors like North Korea. Yet, it is seeking treatment equal to that given to India by the West, the paper opined.
The NYT acknowledged that for decades, India was also penalized for developing nuclear weapons. But attitudes shifted in 2008 when the United States, seeking better relations with one of the world’s fastest-growing economies as a counterweight to China, gave India a pass and signed a generous nuclear cooperation deal that allowed New Delhi to buy American nuclear energy technology.
In order to secure American support for its membership in the 48-nation Nuclear Supplier Group, Pakistan, an American official said, would have to stop pursuing tactical nuclear weapons, which are more likely to be used in a conflict with India and could more easily fall into the hands of terrorists, and halt development of long-range missiles. Pakistan should also sign the treaty banning nuclear weapons tests.
The paper wrote that such moves would undoubtedly be in Pakistan’s long-term interest. It cannot provide adequate services for its citizens because it spends about 25 percent of its budget on defense. Pakistan’s army, whose chief of staff is due to visit Washington this month, says it needs still more nuclear weapons to counter India’s conventional arsenal.
“The competition with India, which is adding to its own nuclear arsenal, is a losing game, and countries like China, a Pakistan ally, should be pushing it to accept that.”
The NYT also had a piece of advice for PM Modi.
“Meanwhile, Narendra Modi, India’s prime minister, has done nothing to engage Islamabad on security issues, and he also bears responsibility for current tensions. The nuclear arms race in South Asia, which is growing more intense, demands far greater international attention.”
The US researchers have discovered a class of immune cells that plays a role in miscarriage, which affects about a quarter of pregnancies.
Researchers at the University of California-San Francisco found that the recently discovered subset of cells known as extrathymic Aire-expressing cells in the immune system may prevent the mother's immune system from attacking the placenta and fetus.
The researchers showed that pregnant mice who did not have this subset of cells were twice as likely to miscarry, and in many of these pregnancies fetal growth was severely restricted.

"When you're pregnant, the immune system is seeing the placenta for the first time in decades -- not since the mother made a placenta when she herself was a fetus," said Eva Gillis-Buck, from UCSF.
"Our research suggests that this subset of immune cells is carrying out a sort of 'secondary education' -- sometimes many years after the better-known population of the educator cells have carried out the primary education in the thymus -- teaching T cells not to attack the fetus, the placenta and other tissues involved in pregnancy," she added. The findings are published in the journal Science Immunology.
The immune system has to be educated not to attack one's own tissues and organs to prevent autoimmune disease. But pregnancy presents a unique challenge since the fetus expresses proteins found in the placenta as well as proteins whose genetics are distinct from the mother.

"It was a conceptual leap to link Aire-expressing cells, which are critical for preventing autoimmune disease, to pregnancy," said Tippi Mackenzie, Professor of Surgery at UCSF's Center for Maternal Foetal Precision Medicine.
In the thymus, Aire-expressing cells begin interacting with other immune cells very early in life to teach them what not to attack. The thymus begins to shrink and is nearly gone by adulthood, by which time most immune cells have been educated. But as the thymus shrinks, the population of eTACs in lymph nodes and the spleen expands, the researchers explained.
The study suggests a healthy pregnancy may depend on having these cells around, they added. (IANS/KB)
The tiny emojis being shared on billions of devices worldwide can play a major role in digital communication, with most people saying that emoji compels them to feel more empathy towards others, according to an Adobe report.
Adobe's global emoji study found that emoji even helps people overcome language barriers and form connections that would otherwise be difficult to do.
"We were surprised and delighted by the discoveries made in the survey, most notably how enthusiastic respondents were for emoji as a means to express themselves," the company said in a statement.

Emojis sometimes get criticized for being overly saccharine, but this sweetness is key when it comes to diffusing some of the heaviness of online communication.
"Many of the emoji are focused on positive emotions, so it's easy to insert them into our conversations and lighten the mood," the Adobe study said.
It's not surprising that over half of those surveyed feel more comfortable using emojis than talking on the phone or in person.

This applies to less intense situations too. Dating, for example, can be tricky — especially when it's online or via digital apps, as it often is now.
The study also found that emoji even helps people overcome language barriers and form connections that would otherwise be difficult to do.
In celebration of World Emoji Day on Saturday, Adobe's '2021 Global Emoji Trend Report' surveyed 7,000 people in the US, the UK, Germany, France, Japan, Australia, and South Korea. (IANS/KB)
Following the grand Richard Branson show where he carried Andhra Pradesh-born Sirisha Bandla and fellow space travelers on his shoulders after successfully flying to the edge of space, it is time for Amazon Founder Jeff Bezos to applaud Sanjal Gavande, one of the key engineers who designed the New Shephard rocket set to take Bezos and the crew to space on July 20.
Billionaire Bezos is set to fly to the edge of space aboard what is touted as the world's first unpiloted suborbital flight. Born in Kalyan, Maharashtra, Gavande is a systems engineer at Blue Origin who always dreamt of designing aerospace rockets.

Bezos, his brother Mark, aviation pioneer Mary Wallace 'Wally' Funk, and other passengers are set to liftoff from west Texas and travel just beyond the edge of space on July 20. Blue Origin announced this week that Oliver Daemen, an 18-year-old high school graduate from the Netherlands, would join the crew.
Oliver is the son of millionaire Joe Daemen, Founder, and CEO of the Dutch investment company Somerset Capital Partners. Blue Origin, however, did not reveal how much Daemen paid for his son's trip to space. Bezos chose July 20 as the launch date to honor the 52nd anniversary of the Apollo 11 moon landing.

The launch site for Blue Origin's first human flight will be in a remote location north of Van Horn, Texas, from where the firm had launched New Shepard for previous flights. Blue Origin has received final approval from the Federal Aviation Administration (FAA) to carry humans on the New Shepard rocket into space.
On July 12, Bandla touched the edge of space with three others, including Virgin Galactic's billionaire CEO Richard Branson. Bandla vaulted into space onboard VSS Unity 22. After the successful spaceflight, Branson carried the Indian-American on his shoulders while celebrating their flight to space, at Spaceport America in New Mexico. (IANS/KB)
