In findings published on Monday in Nature Sustainability, researchers mostly from Pennsylvania State University (Penn State) in the U.S. reported the invention of a new coating that could reduce bacterial growth, water waste, and odor when sprayed onto an ordinary house toilet by rendering its surface too slippery for anything to remain attached for long.

According to the research team, half of all people worldwide are affected by limits on their water supply, while daily fresh water usage to flush the planet’s roughly 1 billion toilets and flush urinals is upwards of 141 billion liters (about 37 billion U.S. gallons, 31 billion imperial gallons); which they note is several times larger than the total rate of water consumption for the continent of Africa. Inventions that render the facilities more water-efficient, they reason, could have a profound impact on wastewater management, sustainable water use, and sanitation, possibly cutting the amount of water used to flush waste by, reportedly, a factor of two.

“Our team” study co-author Tak-Sing Wong said in a press release “has developed a robust bio-inspired, liquid, sludge-, and bacteria-repellent coating that can essentially make a toilet self-cleaning[.]” Wong is Penn State’s Wormley Early Career Professor of Engineering and an associate professor of mechanical engineering and biomedical engineering.

Co-developer Jing Wang recounted, “When we put that coating on a toilet in the lab and dump synthetic fecal matter on it, [the synthetic fecal matter] just completely slides down and nothing sticks to [the coated surface.]”

The more something sticks to a surface, the more water it takes to rinse it off. The researchers reported inventing a coating good at resisting substances that are sticky and vary profoundly in viscosity across their mass—like human fecal matter. They also reported the coating repels bacteria, which has implications for preventing the spread of disease and certainly reduces smells.

The invention, called a liquid-entrenched smooth surface (LESS) coating, involves two separate treatments, both presented as suitable for spraying onto ceramics amongst other materials. The first spray is made of molecularly grafted polymers, specifically polydimethylsiloxane silicone, that Wang described as resembling human hairs — though vastly thinner — once it has dried on the target surface, which makes the surface very smooth. The second spray covers the target surface in silicone lubricant. According to the report, the two-spray process is complete in under five minutes and lasts for roughly 500 flushes before requiring reapplication. Existing treatments have tended to take hours to set.

Carl Hensman of the Bill and Melinda Gates Foundation, which offered a contest for redesigning the toilet some years ago, noted the ingredients in the sprays are also found in commonly used products like — in the case of the first spray — toothpaste, and are unlikely to pollute nearby water supplies; though he also remarked that, because the spray wears off, it was unlikely to be used widely in developing countries as the researchers claim to hope.

Wong and three of his co-authors have started a company, spotLESS Materials, to transform their invention into a product. He remarked, “As a researcher in an academic setting, my goal is to invent things that everyone can benefit from […] As a Penn Stater, I see this culture being amplified through entrepreneurship, and I’m excited to contribute.” They have received support from the Rice Business Plan Competition, Ben Franklin Technology Partners’ TechCelerator, Y-Combinator, and the United States’ National Science Foundation, Department of Energy, and Office of Naval Research.

New Zealand has relaxed the safety rules imposed on internal airlines in 2002, once more allowing passengers to carry pocket knives with blades less than 60mm long and knitting needles.

Other larger items remain banned, including ice-skates, pool cues, hockey sticks, skateboards, cricket bats and harpoons.

Other countries more at risk from terrorism such as the United States of America and Australia will maintain their stricter rules and continue to ban a range of small, sharp objects from their internal flights.

The airlines have also agreed to help return items seized from passengers before boarding.

European finance ministers at the G-20 meeting which opened Saturday, November 20th, are expected to discuss the current exchange rate of the euro vs. the dollar. The euro is currently trading high against the dollar, so that it takes around $1.34 (as of December 4, 2004) to buy one euro. This has the effect of making exports from Europe to the USA more expensive, increasing the likelihood that US consumers will buy from a non-EU country. The exchange rate is set by the currency markets, although it is heavily influenced by the current account status (ie. the balance of trade between countries).

Some European leaders want the United States to take action to increase the value of its exchange rate. The US though is seen as not wanting to do this, for two reasons:

1. A low dollar relative the euro means that all exports from the US to Europe are cheaper for Europeans to buy, increasing the likelihood that Europeans will buy US items and thus helping the US economy
2. Many actions which governments have done in the past to bolster unnaturally their currency have been fought by the market, and the market won. The most famous example is George Soros’ “breaking of the Bank of England”

One side-issue that this discussion might evoke is that of the exchange rate between the dollar and the Chinese yuan, which is fixed by China. Studies of this exchange rate using the concept of purchasing power parity (ensuring that a dollar traded to Chinese yuan will still buy roughly the same amount in China) show that the Chinese yuan has been around 50% undervalued for the past two years. This makes things from China on average 50% cheaper for a US consumer than they should be. US officials have throughout 2004 repeatedly called for China to end this practice. Normally it would end itself, i.e. even with a fixed exchange rate this process could only go on for so long before the entire Chinese market becomes valued differently. But since the Chinese central bank has been constantly lending money to the United States government (via the purchasing of US treasury bonds), that effect is mitigated.

Former Salt Lake City mayor and human rights activist Rocky Anderson took some time to discuss his 2012 U.S. presidential campaign and the newly-created Justice Party with Wikinews reporter William S. Saturn.

Anderson served as mayor of Salt Lake City for eight years (2000–2008) as a member of the Democratic Party. During his tenure, he enacted proposals to reduce the city’s carbon emissions, reformed its criminal justice system, and positioned it as a leading sanctuary for refugees. After leaving office, Anderson grew critical of the Democratic Party’s failure to push for impeachment against President George W. Bush, and for not reversing policies on torture, taxes, and defense spending. He left the party earlier this year and announced that he would form a Third party.

Anderson officially established the Justice Party last week during a press conference in Washington D.C.. He proclaimed “We the people are powerful enough to end the perverse government-to-the-highest-bidder system sustained by the two dominant parties…We are here today for the sake of justice — social justice, environmental justice and economic justice.” The party promotes campaign finance reform and is attempting to appeal to the Occupy Wall Street movement. It is currently working on ballot access efforts, and will hold a Founding Convention in February 2012 in Salt Lake City.

Among other issues, Anderson discussed climate change, health care, education, and civil liberties. He detailed his successes as mayor of Salt Lake City, stressed the importance of executive experience, and expressed his views on President Barack Obama and some of the Republican Party presidential candidates. He spoke in depth about former Massachusetts governor Mitt Romney, with whom he worked during the 2002 Winter Olympics, and fellow Utahan, former governor and U.S. ambassador to China Jon Huntsman, Jr..

China’s National Bureau of Statistics released data Saturday showing that the consumer price index (CPI) for June climbed 6.4% from a year ago. That compares with a 5.5% rise in May, which was the largest since a 6.3% increase in July 2008. The major factor contributing to this figure was the steep rise in food prices which climbed 14.4%. Pork is a major food staple in China, and its price rose 65% from last year.

Analysts predicted that China’s inflation would peak in June, but particularly worrisome was the steep rise in the cost of food from the same time last year and up from 11.7% in May, indicating that Beijing may have difficulty in controlling inflation.

China is the world’s second largest economy, having grown robustly in the last two years driven by a 2009 governmental stimulus package of $586 billion and low interest rates offered by state-owned banks. These were directed at promoting investments in real estate construction and government infrastructure projects, enabling China to lead the global recovery after the collapse of the U.S. mortgage market led to a worldwide recession.

Now Beijing is attempting to slow its fast pace of growth, fearful of inflation, by restricting bank lending and raising interest rates. High inflation along with high property values could hurt the economy. Since October, China’s Central Bank has raised interest rates five times.

Many factors are contributing to China’s inflation, including higher wages for migrant workers, increases in the prices of food and gasoline, as well as diminished output from crucial agricultural areas cause by droughts and flooding this spring.

Today, China’s Premier Wen Jiabao indicated that the war on inflation was continuing and controlling inflation was a top priority for the government, increasing expectations that interest rates would be further increased.

“We must treat stabilising overall price levels as the top priority of our macro-economic controls and keep the direction of macro-economic adjustments unchanged,” Wen said today in comments reported on the central government’s website. He had said in March that the ruling Communist Party is worried that a continuing rise in food prices could result in public protests.

Wen said the government would boost the supply of hogs to keep the price of pork stable, the price of pork being the major contributor to China’s food inflation index and the most closely watched item on it.

“If they signal any comfort with inflation, and inflation is as high as it is now, they could create an environment in which people would panic, and they can have a real problem on their hands,” said Tim Condon, Asian researcher at ING.

As markets worried about the news of Chinese inflation as well as concerns about the European debt crisis, oil dropped below US$95 a barrel today.
