Washington, Sept 24: A new study by researchers at the University of Ottawa has revealed that honey is very effective in killing bacteria in all its forms, especially the drug-resistant biofilms that make treating chronic rhinosinusitis difficult.

In the study, researchers found that in eleven isolates of three separate biofilms (Pseudomonas aeruginosa, and methicicillin-resistant and -suseptible Staphylococcus aureus), honey was significantly more effective in killing both planktonic and biofilm-grown forms of the bacteria, compared with the rate of bactericide by antibiotics commonly used against the bacteria.

New York, Sept 24: US President George Bush has said that his country was ready to extend help to Pakistan to protect its sovereignty, and that Washington looked forward to “deepening our relationship” with its long term anti-terror ally.

Bush said while jointly appearing along with his Pakistani counterpart Asif Ali Zardari before the two attended the UN General Assembly session.

“Your words have been very strong about Pakistan’s sovereign right and sovereign duty to protect your country, and the United States wants to help,” the Daily Times quoted him as saying in New York.

Washington, September 24 : Apart from the Romans giving roads, plumbing, wine and irrigation to Wales, they also introduced leeks in the region.

According to a report by BBC News, the National Museum of Wales has said that the Romans probably planted domesticated varieties of leeks to flavour their stews.

The museum has recreated a Roman-design garden at the National Roman Legion Museum in Caerleon, near Newport.

The garden aims to show how troops posted to the edge of the empire created their own home-from-home.

“We’ve used archaeological remains and research to interpret a Roman garden,” said Andrew Dixey, Estate Manager for National Museum Wales.

Washington, Sept 24 : Ghrelin is known to have an effect on food intake by increasing feelings of hunger and the urge to eat. But now, a new study has shown that it may also be involved in addictive behaviours and brain reward.

Ghrelin is a peptide, mainly produced in the stomach, but also found in small amounts in the brain.

The study examined ghrelin''s role in addictive behaviours and findings indicated that variations in the genes producing ghrelin and its receptor are more common in individuals considered heavy drinkers.

Washington, September 24 : The Department of Homeland Security in the U. S. is testing a body scanner for its efficacy in reading people’s mind, an approach that can make it easy to nail terrorists who can wreak havoc.

The scanner called MALINTENT is the brainchild of the cutting-edge Human Factors division in Homeland Security''s directorate for Science and Technology.

It searches a body for non-verbal cues that can be used to predict whether one has plans to harm one’s fellow passengers.

The system may catch such signals as terrorists and criminals may display in advance of an attack by reading people’s body temperature, heart rate and respiration.

Washington, Sept 24 : US Defence Secretary Robert Gates has said that the greatest threat of terrorism against the US came from the Tribal Areas of Pakistan.

“If you asked me today where the greatest threat to the homeland lies, I would tell you it’s in western Pakistan,” the Daily Times quoted Gates as telling a US Congressional panel.

In the recent past too, US officials have said that Al Qaeda and Taliban fighters used Pakistan’s Tribal Areas a safe haven to launch attacks inside Afghanistan and plot against the US.
