US scientists have developed a new polymer that has a unique capacity to remove pollutant substances from water “in seconds.” The discovery could revolutionize the water-purification industry, make the process cheaper, and involve minimum energy.

A team of researchers from Cornell University made the breakthrough. The full research has been published in Journal Nature this week.

“What we did is make the first high-surface-area material made of cyclodextrin [sugar molecules bound together in a ring],”said Will Dichtel, associate professor of chemistry, who led the research, “combining some of the advantages of the activated carbon with the inherent advantages of the cyclodextrin.”

“These materials will remove pollutants in seconds, as the water flows by,” he said. “So there’s a potential for really low-energy, flow-through water purification, which is a big deal.”

The polymer has already shown the “uptake of pollutants through adsorption at rates vastly superior to traditional activated carbon – 200 times greater in some cases,”says the press release of the university.

According to Dichtel, activated carbons don’t bind pollutants as strongly as the new polymer.

“We knew that [water filtering] would be a likely application if we were successful,” Dichtel says. “We were definitely pleasantly surprised with just how good the performance is.”

Dichtel hopes this new material can open ways to commercial water purification and also improve life in developing countries.

(IraqiNews.com) Anbar – On Sunday, Khalidiya Council in Anbar Province announced, that all elements of ISIS organization had withdrawn from the center of Ramadi to the eastern areas of the city, while pointed out that the organization had taken hundreds of civilians as hostages and human shields.

The head of Khalidiya Council Ali Dawood said in a statement received by IraqiNews.com, “The intelligence information revealed that all ISIS elements had escaped from the center of Ramadi areas to Khalidiya Island east of the city, along with hundreds of civilian hostages,” pointing out that, “The cells of ISIS organization were completely collapsed during the cleansing battles.”

Dawood added, “The organization has taken hundreds of civilians as hostages and human shields during their withdrawal from Ramadi, while the security forces are pursuing the elements of the organization to liberate the abducted civilians.”

My family went to Sweden, I chose India where I felt more accepted: A Syrian refugee

Syrian refugee, 32 (Delhi)

Fled the war-torn country this year and works as Arabic translator in hospitals

A few kilometres away from its DDA houses and across the subzi-mandi in South Delhi’s Sarita Vihar, a narrow lane lined with ‘Forex money exchange’ shops and vendors selling ‘green olives’ leads to a four-storey guest house. The 32-year-old can be often found on its terrace. Here, for the past four years, an “underground” Syrian restaurant has been turning out dishes from back home — syrup-soaked baklavas, pita bread and fresh hummus.

The 32-year-old first came to India from Homs, a city in western Syria, in 2011, when he enrolled for a Masters in English Literature at Jamia Millia Islamia University in Delhi.

He is back here as a refugee — one among the six million Syrians on the run from civil war and Islamic State-unleashed violence. Homs was at the centre of that violence, declared by the rebels as their capital before they were chased out.

In 2013, the 32-year-old and his family — father an engineer, mother an Arabic teacher, and his three siblings — first left for Turkey as “we didn’t feel safe”. “We felt unsettled in Turkey and so decided to move to Europe, like the others,” he says. But when the rest of his family left for Sweden, he came to India — a country where he felt more “accepted”.

In August this year, he officially got “refugee status” from the United Nations High Commission for Refugees. Still, he no longer trusts strangers, and so refuses to be named or even meet face-to-face.

He stays in Jamia Nagar near Sarita Vihar, like he did during his student days, and makes about Rs 15,000-20,000 a month as an Arabic translator at city hospitals, he tells over the phone. Sometimes he takes private tuitions. Sarita Vihar has scores of guest-houses with people from Afghanistan, Iraq, Yemen, etc, some seeking asylum, others looking for affordable medical treatment.

There’s never been a riskier time to use plastic to pay for your holiday shopping. A couple of German security experts found a new flaw in payment terminals – the very thing designed to protect your information – that allows hackers to steal all your money.

Previous attacks exploit software bugs, like you would have on your computer. Ones that can be fixed with a software update,” renowned German code-breaker Karsten Nohl of Security Research Labs in Berlin told RT’s Peter Oliver. “Now, what we’re attacking is the protocol itself. The devices work exactly as intended and are still vulnerable. So this is a risk that cannot easily be fixed with a patch.

Engineers from the University of New South Wales, Australia, have made an important breakthrough that brings quantum computers one step closer to reality.

The team created a quantum version of a standard computer code within a silicon chip. The discovery shows that it is possible to construct realistic and reliable quantum computers.

Quantum computers have the potential to solve problems much more quickly than any computer that exists today, as they combine the rules of informatics to phenomena of quantum mechanics that are not observed in everyday life. Namely, the principle of superposition, popularized by Schrödinger’s cat being both alive and dead, andentanglement.

The specific test conducted in Australia used entanglement to run the code. Entangled particles are created together in a specific way so that their properties, such as energy and momentum, are connected. If a property is changed on one particle, for example during a measurement, the others will be affected as well. The changes are instantaneous, even if the two particles are at opposite ends of the universe, so scientists thought that it might be a violation of special relativity, which dictates that information cannot travel faster than light. Recently, it has been demonstrated that entanglement is a real phenomenon, though.

Hind Al-Mutairi

The Arab Network for Human Rights Information on Thursday denounced the decision by Khalid Al-Faysal, the Emir of Mecca, on 21 December 2015 to bar poet Hind Al-Mutairi from taking part in a function organised in the province because of a poem she recited at the International Book Fair in Jeddah a few days ago.

The sports minister has said that parliament has “better things to be concerned with” than holding a vote on repealing the Hunting Act.

Tracey Crouch said fox hunting is a “pursuit from the past” that should be “consigned to history”, despite a government pledge for a free vote on the issue.

With Boxing Day hunts taking place, a new poll suggests that more than 80% of the public oppose legalising hunting with dogs again.
