Body

Different bodies, different minds

We like to think of ourselves as rational creatures, absorbing information, weighing it carefully, and making thoughtful decisions. But, as it turns out, we're kidding ourselves. Over the past few decades, scientists have shown there are many different internal and external factors influencing how we think, feel, communicate, and make decisions at any given moment.

Immunization for MRSA on the horizon

Methicillin resistant staph aureus (MRSA) infections are resistant to antibiotics and can cause a myriad of problems -- bone erosion, or osteomyelitis, which shorten the effective life of an implant and greatly hinder replacement of that implant. MRSA can result in prolonged disability, amputation and even death.

DNA barcoding of parasitic worms: Is it kosher?

When rabbis from the Orthodox Union started finding worms in cans of sardines and capelin eggs, they turned to scientists at the American Museum of Natural History to answer a culturally significant dietary question: could these foods still be considered kosher?

Do cold consumers like to warm up to romance movies?

Do romance movies warm people up? A new study in the Journal of Consumer Research finds that yes, consumers choose romance movies over other genres when they feel cold.

"We often think of love as being warm. This link between love and warmth appears in everyday language, songs, and poems," write authors Jiewen Hong (Hong Kong University of Science and Technology) and Yacheng Sun (University of Colorado, Boulder). "But is the connection between romantic love and warmth just a metaphor or is there indeed a direct link between romance and physical warmth?"

The consumer mindset: When is a year different than 365 days?

Consumers react differently to units of measurement—depending on whether they are thinking concretely or abstractly, according to a new study in the Journal of Consumer Research.

Reigniting consumer emotions: Why are some experiences better the second time?

Why do people reread books, watch movies multiple times, or visit places again? According to a new study in the Journal of Consumer Research, many people find that repeating experiences "reignites" their emotions.

"Even though people are already familiar with the stories or the places, re-consuming brings new or renewed appreciation of both the object of consumption and their self," write authors Cristel Antonia Russell (American University) and Sidney J. Levy (University of Arizona and Northwestern University). "By doing it again, people get more out of it."

When are consumers loyal to brands? New model helps explain

What makes consumers choose certain products over others? A new study in the Journal of Consumer Research helps explain why consumers change their minds or switch their loyalties.

ORNL explores proteins in Yellowstone bacteria for biofuel inspiration

Studies of bacteria first found in Yellowstone's hot springs are furthering efforts at the Department of Energy's BioEnergy Science Center toward commercially viable ethanol production from crops such as switchgrass.

The current production of ethanol relies on the use of expensive enzymes that break down complex plant materials to yield sugars that are fermented into ethanol. One suggested cheaper alternative is consolidated bioprocessing, a streamlined process that uses microorganisms to break down the resistant biomass.

New subtype of ovarian cancer may be vulnerable to anti-angiogenic drugs

BOSTON--Scientists at Dana-Farber Cancer Institute have identified a subtype of ovarian cancer able to build its own blood vessels, suggesting that such tumors might be especially susceptible to "anti-angiogenic" drugs that block blood vessel formation.

Noncoding RNAs alter yeast phenotypes in a site-specific manner

CAMBRIDGE, Mass. (February 14, 2012) – Personal change can redefine or even save your life—especially if you are one of a hundred yeast cell clones clinging to the skin of a grape that falls from a sun-drenched vine into a stagnant puddle below. By altering which genes are expressed, cells with identical genomes like these yeast clones are able to survive in new environments or even perform different roles within a multicellular organism.

SIV infection may lead to increase in immune-suppressive Treg cells

Tissue in monkeys infected with a close relative of HIV can ramp up production of a type of T cell that actually weakens the body's attack against the invading virus. The discovery, in lymph nodes draining the intestinal tract, could help explain how the HIV virus evades the body's immune defenses.

If the same pattern is found in people infected with HIV, the finding could lead to a treatment strategy that slows the production of this restraining type of T cell. This would let the immune soldiers go after the virus more aggressively.

Following a trail of blood: A new diagnostic tool comes of age

Blood tests have been a mainstay of diagnostic medicine since the late 19th century, offering a wealth of information concerning health and disease. Nevertheless, blood derived from the human umbilical cord has yet to be fully mined for its vital health information, according to Rolf Halden, a researcher at Arizona State University's Biodesign Institute.

Freeze-dried heart valve scaffolds hold promise for heart valve replacement

New Rochelle, NY -- The biological scaffold that gives structure to a heart valve after its cellular material has been removed can be freeze-dried and stored for later use as a tissue-engineered replacement valve to treat a failing heart, as described in an article in Tissue Engineering, Part C: Methods, a peer-reviewed journal from Mary Ann Liebert, Inc. (http://www.liebertpub.com). The article is available free online at http://www.liebertpub.com/ten

Motherhood 'detrimental' to women's scientific careers, study concludes

ITHACA, N.Y. — Women with advanced degrees in math-intensive academic fields drop out of fast-track research careers primarily because they want children – not because their performance is devalued or they are shortchanged during interviewing and hiring, according to a new study at Cornell University.

Finding it difficult to make a purchase? Try creating some distance from the problem

Consumers who are having trouble making decisions can benefit from creating some psychological—or physical—distance, according to a new study in the Journal of Consumer Research.
