Goodbye, Oil: US Navy Cracks New Renewable Energy Technology To Turn Seawater Into Fuel, Allowing Ships To Stay At Sea Longer

Scientists Finally Discover The Function of the Human Appendix

By Barbara Miller

It has long been regarded as a potentially troublesome, redundant organ, but American researchers say they have discovered the true function of the appendix.

The researchers say it acts as a safe house for good bacteria, which can be used to effectively reboot the gut following a bout of dysentery or cholera.

The conventional wisdom is that the small pouch protruding from the first part of the large intestine is redundant and many people have their appendix removed and appear none the worse for it.

Scientists from the Duke University Medical Centre in North Carolina say following a severe bout of cholera or dysentery, which can purge the gut of bacteria essential for digestion, the reserve good bacteria emerge from the appendix to take up the role.

First Tests For Fusion-Powered Spaceship Propulsion Successful

By Mark Hoffman

University of Washington researchers and scientists at a Redmond-based space-propulsion company are currently building components of a fusion-powered rocket, which could enable astronauts to travel to Earth’s neighboring planet Mars within weeks instead of months, at speeds considerably faster than feasible until now. The current travel speeds using fuel rockets make Mars travel a journey of about four years but the new fusion technology being tested by researchers at the University of Washington promises that in 30 to 90 days.

The lab tests have proven to be successful on each part of the process and the scientists are now planning to combine the sections into a one final and overall test.

“Using existing rocket fuels, it’s nearly impossible for humans to explore much beyond Earth,” said lead researcher John Slough, a UW research associate professor of aeronautics and astronautics. “We are hoping to give us a much more powerful source of energy in space that could eventually lead to making interplanetary travel commonplace.”

The team has developed a technology using a special type of plasma that will be encased in a magnetic field. When the plasma is compressed with high pressure by the magnetic field, nuclear fusion takes place.

Israel teams with terror group to kill Iran’s nuclear scientists, U.S. officials tell NBC News

By Richard Engel and Robert Windrem

NBC News

Updated: 11:14 a.m. ET — Deadly attacks on Iranian nuclear scientists are being carried out by an Iranian dissident group that is financed, trained and armed by Israel’s secret service, U.S. officials tell NBC News, confirming charges leveled by Iran’s leaders.

The group, the People’s Mujahedin of Iran, has long been designated as a terrorist group by the United States, accused of killing American servicemen and contractors in the 1970s and supporting the takeover of the U.S. Embassy in Tehran before breaking with the Iranian mullahs in 1980.

The attacks, which have killed five Iranian nuclear scientists since 2007 and may have destroyed a missile research and development site, have been carried out in dramatic fashion, with motorcycle-borne assailants often attaching small magnetic bombs to the exterior of the victims’ cars.

U.S. officials, speaking on condition of anonymity, said the Obama administration is aware of the assassination campaign but has no direct involvement.

The Iranians have no doubt who is responsible – Israel and the People’s Mujahedin of Iran, known by various acronyms, including MEK, MKO and PMI. ….

New vibes in Sindh politics

By Haider Nizamani

PROPRIETORS of media houses dabbling in politics has a long history in South Asia. The power and propaganda nexus is nothing new.

What is somewhat different is the mushrooming of television channels creating new forms of this nexus. Understanding the multifaceted dynamics of this interaction is a relatively unexplored area for the social scientist in Pakistan.

The new kid on Sindh’s political block is Ali Qazi. His family owns the most popular, hence the most powerful, media house of the Sindhi language. Daily Kawish, its flagship newspaper, probably sells more copies than the combined circulation of all its competitors.

Kawish Television Network (KTN) runs a dedicated 24/7 news and current affairs channel and two other channels. Kawish and KTN are household names for the Sindhi reading and viewing public.

Ali Qazi’s recent foray into politics climaxed on Jan 22 in a public meeting in Bhit Shah, a small town in central Sindh where the shrine of the venerated Sindhi poet Shah Abdul Latif Bhitai is located.

English-language dailies treated this rally as a page three news item whereas the largest circulated Sindhi daily, Kawish, went into overdrive to cover the event and published plenty of Op-Eds before and after the rally.

The public meeting was preceded by a month-long campaign of 187 smaller meetings Ali Qazi and his associates held all over Sindh. The purpose? To convince the Sindhi masses to seek change on the lines Mr Qazi is proposing.

What does Mr Qazi’s entrance into politics signify and symbolise? Will he be as successful in politics as he has been in establishing a mammoth media house? Will his politics benefit from his media empire or will the latter suffer due to his politics? Is this a case of conflict of interest? His ambitious entry into politics throws up all these questions.

The Qazis of Hyderabad are no strangers to media and politics. Daily Ibrat, owned by this family, for a long time had the lion’s share of the Sindhi newspaper market. Its current owner, Qazi Asad Abid, has been a member of the National Assembly. His sister, Dr Fehmida Mirza, is the speaker of the National Assembly. Their father, Qazi Abid, was a member of the provincial and national legislatures and held various ministerial portfolios.

Ali Qazi is the nephew of Qazi Abid. In the 1990s, Ali Qazi and his brothers started their own daily, Kawish, which over the years not only challenged the dominance of Ibrat but eventually replaced it as the largest circulated Sindhi newspaper. Ali Qazi, until recently, steered clear of party politics and focused on building his media house. For the past few years, he has championed causes such as the celebration of Sindhi cultural days through his popular print and electronic media outlets. He makes regular, some would say excessive, appearances as an expert and anchor on current affairs programmes on his television channel, KTN.

He uses Op-Ed space in daily Kawish with impunity to share his thoughts with the readers. In these columns he started to float the idea that the Sindhi public aspires for change that mainstream political parties are either unwilling or incapable of providing.

He claims to have become the epitome of the change he has been seeking, thus the name of his group ‘Tabdeeli Pasand (change-oriented). The main ill afflicting Sindh, according to Mr Qazi, is the bhotaar culture. Roughly translated it means the politics of patronage. The answer lies in replacing it with a system based on merit, good governance and transparency.

In the prelude to his Bhit Shah show of Jan 22, the Op-Ed write-ups in Kawish went overboard in portraying Ali Qazi as the saviour Sindh has been waiting for. Contrary to the anticipated announcement of launching his own political party at the Bhit Shah public meeting, Ali Qazi chose to defer that move and stuck to criticising the politics of patronage in Sindh.

As he weighs his options, here are some advantages he enjoys and disadvantages he is likely to encounter should he decide to establish a new political party.

Among his three advantages, the most important is of having access to a well-oiled and sophisticated print and electronic media. He has an edge over any other new entrant in this regard as far as Sindh is concerned.

If the current trend is any indication then he has no compunction in using the KTN-Kawish combo to promote his viewpoint.

Secondly, politics in Pakistan is becoming an expensive undertaking and Ali Qazi has deep pockets to sustain his political venture.

Lastly, lack of effective performance by mainstream parties has created widespread anti-politics sentiment amongst various sections of the middle classes. Imran Khan is exploiting it in Punjab and Ali Qazi is attempting to do the same in Sindh.

The launch of a party by Ali Qazi on his suggested lines will face following hurdles. Firstly, since he owns the most powerful media house in Sindh, his competitors will not give the desired coverage to Ali Qazi’s party. In fact, if the KTN-Kawish combo chooses to become blatantly partisan in promoting Ali Qazi this may provide his competitors an opening to create healthy competition for Sindh viewers.

Left-of-centre politics in Sindh has organisations such as the Awami Tehrik of Rasool Bux Palijo with a political history spanning over several decades over which it has created a reasonably organised party cadre. Assorted Sindhi nationalist parties are a divided lot but they have a collective legacy of creating a secular ethos in Sindhi politics.

Above all, Ali Qazi will have to challenge the PPP’s mighty emotional and electoral support base in Sindh. The PPP has jealously guarded its vote-bank in Sindh for four decades and in the process has weathered many challenges. It has unmatched expertise in constituency-based politics backed up by the Bhutto charisma. Ali Qazi has remained careful in not naming the PPP as the culprit.

If Ali Qazi wants to be an alternative to the PPP in Sindh then he will have to confront the most popular party head-on. If not then his dream of being a change-seeker backed up by his media empire will serve as valuable pressure on PPP politicians to pay closer attention to the kind of issues Ali Qazi is raising.

Pentagon successfully tests hypersonic flying bomb

By AFP

WASHINGTON — The Pentagon on Thursday held a successful test flight of a flying bomb that travels faster than the speed of sound and will give military planners the ability to strike targets anywhere in the world in less than a hour.

Launched by rocket from Hawaii at 1130 GMT, the “Advanced Hypersonic Weapon,” or AHW, glided through the upper atmosphere over the Pacific “at hypersonic speed” before hitting its target on the Kwajalein atoll in the Marshall Islands, a Pentagon statement said.

Kwajalein is about 2,500 miles (4,000 kilometers) southwest of Hawaii. The Pentagon did not say what top speeds were reached by the vehicle, which unlike a ballistic missile is maneuverable.

Scientists classify hypersonic speeds as those that exceed Mach 5 — or five times the speed of sound — 3,728 miles (6,000 kilometers) an hour. …

North Korea paid Pak generals for nuclear secrets

Pakistan’s nuclear-bomb maker says North Korea paid bribes for know-how

By R. Jeffrey Smith

The founder of Pakistan’s nuclear bomb program asserts that the government of North Korea bribed top military officials in Islamabad to obtain access to sensitive nuclear technology in the late 1990s.

Abdul Qadeer Khan has made available documents that he says support his claim that he personally transferred more than $3 million in payments by North Korea to senior officers in the Pakistani military, which he says subsequently approved his sharing of technical know-how and equipment with North Korean scientists.

Khan also has released what he says is a copy of a North Korean official’s 1998 letter to him, written in English, that spells out details of the clandestine deal.

Some Western intelligence officials and other experts have said that they think the letter is authentic and that it offers confirmation of a transaction they have long suspected but could never prove. Pakistani officials, including those named as recipients of the cash, have called the letter a fake. Khan, whom some in his country have hailed as a national hero, is at odds with many Pakistani officials, who have said he acted alone in selling nuclear secrets.

Nevertheless, if the letter is genuine, it would reveal a remarkable instance of corruption related to nuclear weapons. U.S. officials have worried for decades about the potential involvement of elements of Pakistan’s military in illicit nuclear proliferation, partly because terrorist groups in the region and governments of other countries are eager to acquire an atomic bomb or the capacity to build one.

The End (of Religion) Is Near, Scientists Say

Scientists often have a funny way of talking about religion.

By Louis Ruprecht

A case in point concerns a new study that was discussed at the American Physical Society meetings in Dallas, Texas, in late March. Religion, it seems, is going extinct. You heard me: extinct. Dead and gone. Like the dinosaurs.

The data that a team of mathematicians used to reach this rather surprising conclusion were census reports of religious affiliation. Using a complicated means of mathematical analysis called “nonlinear dynamics”—complicated, ironically, because its purpose is to make complicated things simpler by reducing them to one variable—the team attempted to extrapolate from data on religious affiliation in nine countries: Australia, Austria, Canada, Czech Republic, Finland, Ireland, Netherlands, New Zealand and Switzerland.

Turns out, every case of self-reported religious affiliation is trending downward: 40% self-identify as religiously non-affiliated in the Netherlands, as do 60% in the Czech Republic. The mathematicians seem far more surprised by these numbers than most religionists would be. ….

Genetically modified cows produce ‘human’ milk

Scientists have created genetically modified cattle that produce “human” milk in a bid to make cows’ milk more nutritious.

By Richard Gray

The scientists have successfully introduced human genes into 300 dairy cows to produce milk with the same properties as human breast milk.

Human milk contains high quantities of key nutrients that can help to boost the immune system of babies and reduce the risk of infections.

The scientists behind the research believe milk from herds of genetically modified cows could provide an alternative to human breast milk ….
