Hydrodynamics of writing with ink Jungchul Kim, Myoung-Woon Moon, Kwang-Ryeol Lee, L. Mahadevan, and Ho-Young Kim Physical Review Letters (forthcoming) For millennia, writing has been the preferred way to convey information and knowledge from one generation to another. We first developed the ability to write on clay tablets with a point, and then settled on a reed pen, as preserved from 3000 BC in Egypt when it was used with papyrus. This device consisted of a hollow straw that served as an ink reservoir and allowed ink to flow to its tip by capillary action. A quill ...

The Powerhouse Clothing Company is one of South Africa's most flexible and innovative clothing manufacturers. The company is 100 percent dedicated to manufacturing solely in South Africa, despite a growing competition from companies in the East and cheap imports from outside SA being at all time high in the clothing industry. As a result of Powerhouse's aim to be a wholly South African company, its supply chain is one of its most important operating focuses. "If your supply chain is not working in tandem together then everything falls apart," notes Justin Mansfield, ...

Costs for second-generation ethanol processing, which will ease the stress on corn and sugarcane, are unlikely to be competitive until 2020, according to a unique Queen's University study. "This study really lays out in black and white where we are and where we are going," says Warren Mabee, an assistant professor in the School of Policy Studies and Department of Geography. "It should prompt companies to reassess (their processes going forward)." The researchers found that building large scale facilities for second-generation ethanol production will be more costly than ...

Only a few decades ago, scientists discovered the existence of "sprites" 30 to 55 miles above the surface of the Earth. They're offshoots of electric discharges caused by lightning storms, and a valuable window into the composition of our atmosphere. Now researchers at Tel Aviv University say that sprites are not a phenomenon specific to our planet. Jupiter and Saturn experience lightning storms with flashes 1,000 or more times more powerful than those on Earth, says Ph.D. student Daria Dubrovin. With her supervisors Prof. Colin Price of TAU's Department of Geophysics ...

MADISON – Hydrogen peroxide isn't just that bottled colorless liquid in the back of the medicine cabinet that's used occasionally for cleaning scraped knees and cut fingers. It's also a natural chemical in the body that rallies at wound sites, jump-starting immune cells into a series of events. A burst of hydrogen peroxide causes neutrophils, the immune system's first responders, to rush to the wound to fight microorganisms, remove damaged tissue and then start the inflammation process. University of Wisconsin-Madison researchers now have discovered the molecular ...

Genetically modified animals are designed to contain the spread of pathogens. One prerequisite for the release of such organisms into the environment is that the new gene variant does not spread uncontrollably, suppressing natural populations. Scientists at the Max Planck Institute for Evolutionary Biology in Plön, Germany, have now established that certain mutations are maintained over an extended period if two separate populations exchange individuals with one another on a small scale. The new gene variant may remain confined to one of the two populations. The migration ...

A new model developed by scientists of the European Commission's Joint Research Centre (JRC) allows the potential presence of bluefin tuna to be tracked through daily updated maps, helping to protect endangered stocks and fight illegal fishing. The model, based on satellite remote sensing data, provides for the first time an overall view of the preferred bluefin tuna habitats in the Mediterranean Sea, as well as their changes over time. Satellite-based habitat mapping can help identify more precisely areas to be inspected or to be closed for fisheries and it can also help ...

FAIRFAX, Va., November 21, 2011—People who believe there is a lot of disagreement among scientists about global warming tend to be less certain that global warming is happening and less supportive of climate policy, researchers at George Mason, San Diego State, and Yale Universities report in a new study published in the journal Nature Climate Change. A recent survey of climate scientists conducted by researchers at the University of Illinois found near unanimous agreement among climate scientists that human-caused global warming is happening. This new George Mason ...

Can dementias and mild cognitive impairment be influenced in their course by diseases and risk factors? This is the subject of a study reported by Thorleif Etgen and co-authors in the current issue of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2011; 108[44]: 743-50). Increasingly larger numbers of people are affected by mild cognitive impairments and even dementia, which means that early detection of possible precursors as well as diagnosis and therapy of risk factors that can actually be influenced are gaining in importance. The term "mild cognitive impairment" ...

NEW YORK (Nov. 21, 2011) -- Older adults receiving home health care may be taking a drug that is unsafe or ineffective for someone their age. In fact, nearly 40 percent of seniors receiving medical care from a home health agency are taking at least one prescription medication that is considered potentially inappropriate to seniors, a new study in the Journal of General Internal Medicine has revealed. The study's researchers, led by Dr. Yuhua Bao, assistant professor of public health at Weill Cornell Medical College, found that home health care patients aged 65 and over ...

Financial incentives work for doctors. Could they work for patients, too? Could they encourage them to change unhealthy behaviors and use preventive health services more? In some cases, yes, according to Dr. Marita Lynagh from the University of Newcastle in Australia, and colleagues. Their work, looking at why financial incentives for patients could be a good thing to change risky health behaviors, indicates that incentives are likely to be particularly effective at altering 'simple' behaviors e.g. take-up of immunizations, primarily among socially disadvantaged groups. ...

EUGENE, Ore. -- (Nov. 21, 2011) -- An anti-cancer drug used extensively in chemotherapy binds pervasively to RNA -- up to 20-fold more than it does to DNA, a surprise finding that suggests new targeting approaches might be useful, according to University of Oregon researchers. Medical researchers have long known that cisplatin, a platinum compound used to fight tumors in nearly 70 percent of all human cancers, attaches to DNA. Its attachment to RNA had been assumed to be a fleeting thing, says UO chemist Victoria J. DeRose, who decided to take a closer look due to recent ...

AMES, Iowa - Research at Iowa State University has led to discovery of a genetic method that can increase biomass in algae by 50 to 80 percent. The breakthrough comes from expressing certain genes in algae that increase the amount of photosynthesis in the plant, which leads to more biomass. Expressing genes means that the gene's function is turned on. "The key to this (increase in biomass) is combination of two genes that increases the photosynthetic carbon conversion into organic matter by 50 percent over the wild type under carbon dioxide enrichment conditions," said ...

COLUMBIA, Mo. – Nursing is among construction and law enforcement as one of seven professions reporting the most on-the-job injuries, according to the U.S. Department of Labor. Sprains, strains or tears due to overexertion account for many of the injuries. Those injuries often can be attributed to improperly lifting, handling and moving patients. Now, nursing students at the University of Missouri have a new facility that will help them develop skills to keep themselves and their patients safe. An unused locker room in the Sinclair School of Nursing has been ...

WASHINGTON -- The less people know about important complex issues such as the economy, energy consumption and the environment, the more they want to avoid becoming well-informed, according to new research published by the American Psychological Association. And the more urgent the issue, the more people want to remain unaware, according to a paper published online in APA's Journal of Personality and Social Psychology. "These studies were designed to help understand the so-called 'ignorance is bliss' approach to social issues," said author Steven Shepherd, a graduate ...

KENNEDY SPACE CENTER — NASA's Mars Science Laboratory mission, which is scheduled to launch this week, has the potential to be the most productive Mars surface mission in history. That's due in part to its nuclear heat and power source. When the rover Curiosity heads to space as early as Saturday, it will carry the most advanced payload of scientific gear ever used on Mars' surface. Those instruments will get their lifeblood from a radioisotope power system assembled and tested at Idaho National Laboratory. The Multi-Mission Radioisotope Thermoelectric Generator is the ...
