In this equation, it's probably pretty obvious what you should do. But is your life ruled by should? Do you gimp through your week yessir-ing and nomam-ing and cowtowing to avoid punishment? Okay, so do most of us—but here's your chance to break the mold and stike a blow for the proletariat (viva la revolucion...). And at least if you get caught blowing off the rest of the day in favor of a four-hour, three-martini, expense account lunch at the pub, you can blame the numbers.

Should I order a sandwich at my desk or head to the bar on the corner for a blowout lunch?

People who see the world as essentially fair can just maintain this perception through a diminished sense of moral outrage, according to a study by researchers in New York University's Department of Psychology. The findings appear in the March issue of the journal Psychological Science, which is published by the Association for Psychological Science.

Psychologists have long studied system-justification theory, which posits that people adopt belief systems that justify existing political, economic, and social situations or inequities in order to make themselves feel better about the status quo. Moreover, in order to maintain their perceptions of the world as just, people resist changes that would increase the overall amount of fairness and equality in the system.

The function of an enzyme in the brain – strongly linked to a number of major brain diseases such as Alzheimer's, schizophrenia and bi-polar disorder – has been identified for the first time by researchers at the University of Bristol, UK.

These findings, published today in Neuron, will help in the understanding of how memories are laid down and what goes wrong in these disorders.

The research showed how controlling the activity of glycogen synthase kinase-3 (GSK3) might prevent a memory being erased by improving the strength of connections between neurons in the brain, thus allowing better consolidation of new information.

Professor Collingridge from the University of Bristol said: "While GSK3 has previously been implicated in major neurological disorders, until now its rol

Using a state-of-the-art technique to map neurons in the spinal cord of a larval zebrafish, Cornell University scientists have found a surprising pattern of activity that regulates the speed of the fish’s movement. The research may have long-term implications for treating injured human spinal cords and Parkinson’s disease, where movements slow down and become erratic.

The study, "A Topographic Map of Recruitment in Spinal Cord," published in the March 1 issue of the journal Nature, maps how neurons in the bottom of the fish’s spinal cord become active during slow movements, while cells further up the spinal cord activate as movements speed up.

Researchers have used the world's thinnest material to create a new type of technology, which could be used to make super-fast electronic components and speed up the development of drugs.

Physicists at The University of Manchester and The Max-Planck Institute in Germany have created a new kind of a membrane that is only one atom thick.

It's believed this super-small structure can be used to sieve gases, make ultra-fast electronic switches and image individual molecules with unprecedented accuracy.

The findings of the research team is published today (Thursday 1 March 2007) in the journal Nature.

Two years ago, scientists discovered a new class of materials that can be viewed as individual atomic planes pulled out of bulk crystals.

These one-atom-thick materials and in

A new study suggests that the iron-rich winter runoff from Pacific Northwest streams and rivers, combined with the wide continental shelf, form a potent mechanism for fertilizing the nearshore Pacific Ocean, leading to robust phytoplankton production and fisheries.

The study, by three Oregon State University oceanographers, was just published by the American Geophysical Union in its journal, Geophysical Research Letters.

West coast scientists have observed that ocean chlorophyll levels, phytoplankton production and fish populations generally increase in the Pacific Ocean the farther north you go (from southern California to northern Washington).

A new vaccine delivery system using microspheres of a biodegradable polymer may not only reduce the need for booster shots in some cases, but also appears to stimulate an immune response that traditional vaccines do not. Researchers from Iowa State University report their findings today at the ASM Biodefense and Emerging Disease Research Meeting.

"Current vaccines are good at producing antibodies that block entry into the cell. In the case of some diseases, such as malaria or tuberculosis, antibody vaccines just aren't effective," says Jenny Wilson-Welder, a lead researcher on the study.

In the largest study of its kind, surgeons at Hospital for Special Surgery have determined that by modifying a classic ligament surgery, they can return more athletes, such as baseball players, to their prior level of competition. The modified surgery repairs a torn medial collateral ligament (MCL), which links and stabilizes bones of the lower and upper arm where they meet at the elbow. 

Less traumatic than the classic Tommy John surgery, the modified surgery called the docking procedure, with time, is likely to become the gold standard for treating these injuries.

A national survey of commercial health plans has found that most plans provide online information regarding mental health and substance abuse but few provide clinical services such as counseling via the Internet. The nationally representative health plan survey, published in Psychiatric Services, and led by Dr.

Researchers have taken advantage of the unique coupled semiconducting and piezoelectric properties of zinc oxide nanowires to create a new class of electronic components and devices that could provide the foundation for a broad range of new applications.

So far, the researchers have demonstrated field-effect transistors, diodes, sensors – and current-producing nanogenerators – that operate by bending zinc oxide nanowires and nanobelts.
