Independent research, involving over 3 million Italians, conducted by Henley Management College and the University of Milan has concluded that the prescription costs for men over the age of 65 is significantly higher than it is for women.

The primary objective of this study was to make the first step in the modelling of pharmaceutical demand in Italy to improve the governance of prescribing funds.

The research found that the mean annual prescription cost per individual was similar for males (196.13 euro) and females (195.12euro). However after 65 years of age, the mean prescribing costs for males were significantly higher than females. On average, costs for a 75-year-old man would be 12 times the costs for a 25-34 year-old subject if male, 8 times if female.

Like the surface motif of a bubble bath, the spatial distribution of a magnetic field penetrating a superconductor can exhibit an intricate, foam-like structure. Ruslan Prozorov at the U.S. Department of Energy’s Ames Laboratory has observed these mystifying, two-dimensional equilibrium patterns in lead samples when the material is in its superconducting state, below 7.2 Kelvin, or minus 446.71 degrees Fahrenheit.

Anybody who’s tried to concentrate on work while suffering a headache knows that pain compellingly commands attention—which is how evolution helped ensure survival in a painful world. Now, researchers have pinpointed the brain region responsible for pain’s ability to affect cognitive processing. They have found that this pain-related brain region is distinct from the one involved in cognitive processing interference due to a distracting memory task.

To search for the region responsible for pain’s ability to usurp attention, Ulrike Bingel and colleagues at the University Medical Center Hamburg-Eppendorf asked volunteers to perform a cognitive task involving distinguishing images, as well as a working memory task involving remembering images.

We all share our genetic make up with relatives, but should we also share ownership of the results of DNA analysis or should this knowledge be considered private?

Dr Anneke Lucassen, a clinical geneticist at the University of Southampton, believes that if anyone is to own genetic information, it has to be all those who have inherited it and, more importantly, it must be available to all those who might be at risk.

The question, she says, is how to balance a right to privacy with disclosing risks to others.

Should a ban on smoking exempt people who do it for 'cultural' reasons? What if the science regarding the detrimental effects of certain types of smoking is inconclusive?

This is an issue lawmakers in the UK will have to struggle with as advocates try to get hookah smoking exempted from England’s smoking ban.

A hookah is a glass waterpipe. It has primarily been used in Arabic communities for smoking herbal fruits after meals, but it has become popular among young people for smoking tobacco, massel (aromatic tobacco), cannabis and the cheaper bango, write Dr Rashid Gatrad and colleagues.

At the annual meeting of the American Society of Plant Biologists in Chicago, Dr. Jorge Zavala, Sr. of the Institute for Genomic Biology at the University of Illinois, and colleagues showed that elevated CO2 may negatively impact the relationship between some plants and insects.

Elevated CO2 is considered to be a serious catalyst of global change. Its effects can be felt throughout the ecosystem, including the insect-plant food chain link. Safeguarding highly-usable crops is of great importance to many local and national economies.

NASA's Cassini spacecraft has revealed for the first time surface details of Saturn's moon Hyperion, including cup-like craters filled with hydrocarbons that may indicate more widespread presence in our solar system of basic chemicals necessary for life.

Hyperion yielded some of its secrets to the battery of instruments aboard Cassini as the spacecraft flew close by in September 2005. Water and carbon dioxide ices were found, as well as dark material that fits the spectral profile of hydrocarbons.


This map shows the composition of a portion of Hyperion's surface.

Andrew Gelman astutely noted that the three researchers (Michel Cabanac, Anthony Sclafani, and Israel Ramirez) whose work I used the most to come up with the Shangri-La Diet were not at Harvard or Yale or Rockefeller University. Isn’t that where breakthrough research is supposed to come from? This wasn’t the only way that development of the Shangri-La Diet was not quite “right”:

1. The research of Cabanac et al. got little recognition. The set point idea arose in the 1950s, or even earlier. In the 1970s, Cabanac saw very clearly that your set point depends on what you eat. With Rabe, he did an excellent experiment supporting this view. Not one weight-control researcher took note. No other lab built on this work.

From Al Gore's "An Inconvenient Truth" to heated Congressional debates about federal tax incentives for new alternative fuels, the issue of coal's place in supplying America's energy and fuel needs has taken on added importance in recent months.

A research institute at the University of Kentucky, though, has been exploring ways to increase the efficiency of converting coal to liquid fuel well in advance of national discussions of the process.

At the UK Center for Applied Energy Research (CAER), Burt Davis is refining the process to identify ways to reduce or capture carbon dioxide generated by the Fischer-Tropsch method of converting coal to diesel and other products, such as paraffin and chemicals for making plastics.

Scientists' hunt for the cause of depression has implicated so many suspects and found so many treatments with different mechanisms that the condition remains an enigma. Now researchers at the Stanford University School of Medicine have identified one unifying principle that could explain how a range of causes and treatments for depression converge.

They found that in rats the differing mechanisms of depression and its treatment in the end appear to funnel through a single brain circuit. Changes in how the electrical signals spread through the circuit appear to be the cause of depression-related behavior, according to their study.
