Efficient DNA-Based Computing Could Replace Silicon

“DNA is the future of computing,” Jian-Jun Shu tells PhysOrg. And why not? Silicon is slow by comparison, computes in a binary system, creates waste heat, and is not particularly easy on the environment. DNA-based computing can perform better than silicon in several respects, Shu says, and he and a few of his students at Nanyang Technical University in Singapore have set out to prove it.

The general idea: the human body performs computations all of the time, and does so far faster than even the fastest silicon-based supercomputer. Moreover, it does so in a parallel fashion, working with more breadth, speed, and agility than the ones and zeros of silicon computation. For massive parallel problems, artificial intelligence problems, and combinatorial problems, DNA-based computing could be far more efficient.

How does it work? Shu and company are just starting to scratch the surface of what DNA computing could do, he admits, but in the lab he and his students have manipulated strands of DNA to do all kinds of things. They have fused strands together, broken them apart, snipped them, and Read more…

Frightening crisis evolves bearing
unsettling similarities to 1962 Cuba…
except this time facing advanced air defenses


German Newspaper Die Welthas for months been reporting surreptitious scheming between Chavez and Ahmedinijad, and the latest fruit of this most unholy alliance is now ready for us to choke-on-down.Engineers from a construction company operated by Tehran’s Republican Guards already surveyed sites back in February, and are reportedly putting into action plans for both defensive and offensive installations of Iranian missiles on the Paraguana Peninsula in the far north-west of Venezuela…

You’d have to be pretty deep in denial to not see how these ambitious despots are moving beyond the rhetoric stage with haste, bound and determined to threaten the United States militarily as well as economically… and why not: they know perfectly well that Obama’s not going to do anything, he actually seemed to harbor a man-crushon the both of them in 2009.And can you imagine these little Hitlers trying anything like this on Reagan’s watch? Say what you like about Trump, but only he and John Bolton ever even touched on Read more…

CBN’s quest for a cashless economy

The Central Bank of Nigeria (CBN) recently pegged a limit of daily cash withdrawal and lodgment with commercial banks by any individual and corporate customer to N150,000 and N1 million respectively, effective from June 1. This latest development, according to the apex financial regulatory authority is coming on the heels of increasing dominance of cash in the economy with its implication for cost of cash management to the banking industry, security, money laundering, among others. While some stakeholders said that the directive was in the right direction, others argued that the country has not developed enough for such policy. In this report, Group Business Editor, ROTIMI DUROJAIYE, samples the opinions of a cross-section of Nigerian and concludes that the CBN should be more creative in its drive towards cashless economy to avoid strangling the economy itself.

The banking regulatory authority, which disclosed the latest directive on April 28 in a circular entitled “Industry Policy on Retail Cash Collection and Lodgement,” signed by its Director of Currency Operations Department, Muhammad Nda, warned that individuals and corporate organisations that flout the limits would be charged penalty fees of N100 per thousand and N200 per thousand respectively.

CBN, which pointed out that the policy was adopted to reduce high usage of cash and  moderate the cost of cash management  as well as  encourage the use of electronic payment channels,  stated  that it took the decision in collaboration with the bankers’ committee.

It threatened to suspend any bank, payments scheme, processor, switching company or service provider that contravenes the policy for a Read more…

An archaeological team in the Bayuda Desert in northern Sudan has discovered dozens of new rock art drawings, some of which were etched more than 5,000 years ago and reveal scenes that scientists can’t explain.

The team discovered 15 new rock art sites in an arid valley known as Wadi Abu Dom, some 18 miles (29 kilometers) from the Nile River. It’s an arid valley that flows with water only during rainy periods. Many of the drawings were carved into the rock faces — no paint was used — of small stream beds known as “khors” that flow into the valley.

Some of the sites revealed just a single drawing while others have up to 30, said lead researcher Tim Karberg, of the Westfälische Wilhelms- Read more…

Fail

This is the age of being perpetually connected. If you have a Twitter, Facebook or any other sort of account, your information is out there. The best thing to do is just keep the information you don’t want people to know offline. It’s just safer that way.

Now, let’s take a look at the times that the major companies have failed, big time. There are several of them, here they are.

1) Texas Workforce Commission – Identities Released: Social Security Numbers, Addresses, etc.

My home state (note: everyone on iSmashPhone is from a different part of the world). It was recently found that Social Security numbers, driver’s license numbers and other personal info, according to website ComputerWorld. Two security chiefs were fired over it, and while the Attorney General’s office says that there is no evidence that the exposed data has been misused, they did say that we should be careful about being targets of a new phone scam. Here is that press release. And everyone is worried about Apple? This was personal info for people who truly had no choice in the Read more…

Google chairman and CEO Eric Schmidt came out to defend tracking technology in smartphones arguing the technology will ultimately enrich and benefit the lives of consumers.

Recent debates regarding privacy have surfaced following the discovery of tracking files native to Apple’s iPhone and Google’s Android mobile operating system.

Today, you’re phone knows who you are, where you are, where you’re going, to some degree, because it can see your path. And with that and with your permission, it’s possible for software and software developers to predict where you’re going to go, to suggest people you should meet, to suggest activities and so forth,” he said. “So ultimately what happens is the mobile phone does what it does best, which is remember everything and make suggestions.”

Allowing your phone to know you, follow you and help you will allow users to enjoy their social experience more, he contended. The experience of will become increasingly Read more…

US government will soon seize your retirement account

NaturalNews) – When it comes to your retirement account, you probably keep an eye on Wall Street and the financial markets because when they lose value, your account loses value. Little did you know you are going to have to keep an eye on Uncle Sam as well, because he’s eyeing your retirement too, and he could soon take what he will claim is his fair share of it.

If you think that sounds absurd, think again. In fact, it’s a concept that is already being used by some governments, the most recent of which is Ireland.

In a bid to finance a “jobs” program, the Irish government, which is heavily in debt, is set to impose a new levy – read “tax” – on private retirement accounts. The accounts of government workers will be exempt.

“It’s truly disgusting logic to force private workers to pay for years of political incompetence while absolving government employees,” writes Simon Read more…
