British PM David Cameron has warned his Conservative lawmakers not to air their grievances about the party’s dismal poll ratings and his leadership on Twitter, reports said Wednesday.

Cameron and his new party strategist Lynton Crosby, who helped Australia’s John Howard win four elections, told Tory MPs they risked damaging their prospects for the 2015 general election.

According to the Daily Mail newspaper, Cameron’s office said backbenchers were “participants, not commentators” after a string of what it called “distracting” comments on the social media website.

However, the prime minister’s warning about Twitter appeared to have fallen on deaf ears.

Lawmaker Sarah Woollaston, said: “I cannot ‘participate’ without the freedom to ‘comment’, even if that is sometimes inconvenient to the Executive,” she tweeted.

New method for clean, cheap water developed

A defence contractor better known for building jet fighters and lethal missiles says it has found a way to slash the amount of energy needed to remove salt from seawater, potentially making it vastly cheaper to produce clean water at a time when scarcity has become a global security issue.

The process, officials and engineers at Lockheed Martin Corp say, would enable filter manufacturers to produce thin carbon membranes with regular holes about a nanometer in size that are large enough to allow water to pass but small enough to block molecules of salt in seawater.

Earth-like planets three times more than thought

The number of Earth-sized and potentially habitable planets is three times higher than previously believed, an Indian-origin scientist has claimed.

Some of those planets are likely lurking around nearby stars, according to Ravi Kopparapu, a post-doctoral researcher in geosciences in the Penn State University.

“We now estimate that if we were to look at 10 of the nearest small stars we would find about four potentially habitable planets, give or take,” Kopparapu said.

Bitter melon juice may prevent pancreatic cancer

Scientists including one of Indian-origin have discovered that juice from bitter melon also known as bitter gourd or ‘karela’, used for centuries against diabetes in the folk medicines of India and China, can prevent pancreatic cancer.

Researchers from the University of Colorado Denver found that bitter melon juice restricts the ability of pancreatic cancer cells to metabolise glucose, cutting the cells’ energy source and eventually killing them in mouse models.
