IRE 210/10 Overs: 45 RSA won by 201 runs
While previous studies have linked nut consumption to a lower risk of heart disease, diabetes, and high blood pressure, the earlier research focused mostly on wealthier white people in the US and Europe. This study, with a more ethnically and economically diverse population in the US and China, suggests that nuts can benefit people from a wide variety of backgrounds
“We can now tell people that peanuts are just as good as more expensive tree nuts, and that the benefit isn’t just for white, upper class people, it’s for everybody,” said senior study author Dr Xiao-Ou Shu, a professor of epidemiology at Vanderbilt University School of Medicine in Nashville, in a phone interview.
Shu’s team studied 71,764 people in the southeastern US – mostly low-income, and about two-thirds African-American – and 134,265 residents of Shanghai.
They looked at how many grams of peanuts and other nuts participants ate on an average day and sorted them into five groups ranging from a low of less than 0.95 grams to a high of at least 18.45 grammes. A peanut – which is technically not a nut – weighs about one gramme and there are about 28 peanuts in a one ounce serving.
The Chinese participants ate far fewer nuts than the Americans and in both countries women generally ate less than men. Average daily nut consumption ranged from a low of 1.6 grammes for Chinese women to a high of 16.4 grammes for white men in the US south.
In the American study, half the people were tracked for at least five years. In the Chinese group, half were tracked for six to 12 years. For the Americans, the risk of dying from any cause was 21 percent lower in the group that ate the most peanuts, compared to the group that ate the least. For the Chinese, the risk reduction was 17 percent.
Nuts and peanuts also lowered the risk of death from strokes and heart disease in both study groups, but not the risk of death from cancer or diabetes.

Helplessly stuck in a patch of mud, this tiny zebra foal appeared doomed to a prolonged and agonizing death.
Then along came the most unlikely of rescuers – a gigantic bull rhino who had been attracted by the creature’s desperate struggles and mewling cries.
It was the work of a moment for the enormous animal to hoist the foal out of the mud and to safety. But tragically this was one rescue that did not have a happy ending. Oblivious to its own strength, the rhino ended up impaling the zebra on its horn.
Roel van Muiden, a field guide and wildlife photographer, spotted the foal stuck in a deep and pitiless patch of mud while he was showing visitors around the Madikwe Game Reserve in South Africa.
Nearby a bull rhino was chasing some females, then being chased away in return, but the foal’s mother and her herd were nowhere to be seen.
‘The foal must have been there for quite some time,’ wrote Mr van Muiden in Africa Geographic.
The bull rhino, he went on, finally gave up on his futile advances. Wandering down to the water, he found the hapless foal. Curious, the huge beast began prodding the youngster with his horn.
After a while the bull, growing impatient with his toy, sank his snout deep into the mire before quickly lifting the foal from the mud. This was no altruistic rescue mission, having helped it escape the morass he merely dropped the animal and wandered off.
But then he came back to the exhausted youngster for another look. Apparently wanting to see the foal from another angle, he used his horn to move it into a different position, and disembowelled it.
Dropping it again, the bull flopped to the mud himself for a roll-around, almost crushing the dying baby zebra. The stricken animal didn’t last much longer.
Mr van Muisen said many things went through his mind as he watched the tragedy unfold, but his foremost thought was to ‘let nature be nature’.
‘I have had many comments from people seeing the photos asking why I did not retrieve the foal from the mud,’ he said.
‘The zebra’s herd was gone so even if I could have, he would not have survived as his mother and harem were nowhere to be seen and thus he would have died from starvation.’
Mr van Muisen added that the foal’s mother probably knew her child was caught in a hopeless situation. She probably had good reason for abandoning it to its fate, he said.
Despite the foal’s sad and early end, he said he felt lucky to see what he described as ‘an amazing interaction between two species.’
‘I have been guiding for almost ten years and may go on for many and still never witness something as amazing and melancholy as this.’
KARACHI: He is doing Pakistan proud, and feels his work is one way the image of Pakistan can be improved globally. Yet, this celebrated final-year computer science student at Bahria University has not yet received the recognition he deserves.
The world’s leading information security publications have featured Pakistani security researcher, Rafay Baloch, as one of the top ethical hackers in 2014, putting the 21-year-old Karachiite on top of their lists, The Express Tribune learnt on Thursday.
“Ethical hacking, which makes the information world more secure, is one way we [Pakistanis] can change our country’s negative perception in the world,” said Baloch.
CheckMarx, a source code analysis company based out of Tel Aviv, Israel, recognised Baloch as one of the world’s top five ethical hackers who made the headlines in 2014 for exposing a serious vulnerability – a Same-Origin Policy (SOP) bypass – in Android’s Open Source Platform browser (versions older than 4.4).
The recognition comes from a company that has, arguably, the best tool for Static Application Security Testing. CheckMarx was ranked number one for static analysis in “Critical Capabilities for Application Security Testing”, a 2014 report by the world’s leading information technology research and advisory company, Gartner.
“Contrary to common belief, many high-profile hackings in 2014 were performed by ethical hackers interested only in the benefit of the community,” CheckMarx said in a blog post on December 31, 2014, terming 2014 the year of the mega attacks, such as the Snapchat fiasco, iCloud photo leaks and North Korean orchestrated Sony Pictures hacking.
“Rafay Baloch took the world by storm after finding glaring flaws in Android’s stock AOSP browser,” read the post, putting Baloch on top of their list, which also featured ethical hackers from Israel, Egypt and Switzerland among top five in the world.
According to CheckMarx, the security loopholes identified by the Pakistani white hat “have not been addressed and are allowing hackers to steal session cookies to this very day, enabling them to perform a wide variety of malicious actions including identity theft”.
According to the world’s leading information security magazine based out of New York City,The SC Magazine, “Baloch has responsibly disclosed hundreds of vulnerabilities in his roughly six-year career in security research. His biggest discovery may be CVE-2014-6041, a bug that could allow a bad actor to circumvent the AOSP browser’s SOP”. The magazine published this on December 8, 2014 in an article titled Reboot 25: Threat seekers.
The magazine added that it was a significant issue; it was covered by major news outlets and was deemed a privacy disaster by security experts, and at the time impacted approximately 75 per cent of Android users running platforms older than version 4.4.
Though none of the two publications ranked the security researchers covered in their reports, both put Baloch on top of their list.
A professional penetration tester and author of “Ethical Hacking and Penetration Testing Guide”, his first book on internet security, Baloch has been participating in various bug bounty programs to help several major internet corporations improve their internet security. He was rewarded with $10,000 in cash and a job offer from PayPal, a global online payment solution, for finding remote code execution vulnerability along with several other high-risk vulnerabilities inside PayPal.
Despite the international recognition, the Pakistani security researcher who released three more security bugs in different Android browsers even on the last day of 2014 hardly got any attention from national news channels.
“Being a Pakistani, I feel great to be recognised by an Israeli company,” Baloch said, responding to a question. CheckMarx was founded by Maty Siman, former advisor to the Israeli Prime Minister’s Office on IT security, who also worked in the computer unit of Israeli Defence Forces.
