Putting feelings into words produces therapeutic effects in the brain

...s anger’ is what we do in this study, where people look at an angry face and say, ‘this is anger,’” Lieberman noted. Creswell said Lieberman has now shown in a series of studies that simply labeling emotions turns down the amygdala alarm center response in the brain that triggers negative feelings. ...

Extra-aggressive form of idiopathic pulmonary fibrosis identified

...attention to the time of onset of symptoms, and to look for other signs that allow the identification of these rapid progressor patients". In this study the authors performed global gene expression analysis and other molecular studies in a subset of patients and identified a number of genes that were ...

Moths mimic sounds to survive

...is similar to the way birds avoid butterflies that look like the bad-tasting Monarch. The two species of bats used were big brown bats and red bats. Barber raised the bats in the lab so behavior learned in the wild would not influence the results of the experiment. Barber said anecdotal observati...

Smallpox outbreak: How long would it take for vaccines to protect people? Would it work?

...rus). This study at Saint Louis University will look at the ability of an investigational vaccine made by Bavarian Nordic to stimulate the immune system against smallpox. "Vaccines prevent disease by giving the body a jump-start at recognizing the infecting virus or bacteria," said Sharon Frey, M.D....

Mice with a migraine show signs of brain damage

...Nedergaard’s team was able to get an unprecedented look at the events that happen in the brain of a mouse ...icated laser system known as two-photon imaging to look at the activity of live cells in the intact brain of a mouse. They combined that with a new techniqu...

A cherry on top: Tart cherries may alter heart/diabetes factors

Alien plants attack using 'resource conservation' as weapon, researchers say

...e lists of potential invaders, he said. Scientists look at a variety of factors to assess which plants sho.... "With this new information, we can now take a look at those lists with the thought in mind that we better consider adding species that are really resou...

Traumas like Sept. 11 make brains more reactive to fear

...) or major depression. One of the first studies to look at the effects of trauma on the brains of healthy people, it is published in the May issue of the journal Emotion. "These people appear to be doing okay, but they may, indeed, be having more sensitive responses to upsetting stimuli," said Elise Tem...

New technique will produce a better chromosome map

... in living systems, this is the first structure to look at," Novikov said. "This is the starting point: the appearance of the genes themselves." Cell and developmental biology professor and lead investigator Andrew S. Belmont and visiting scientist Igor Kireev, of Moscow State University, are co-author...

Genetic roots of bipolar disorder revealed by first genome-wide study of illness

...r the results apply to other populations, and will look for common variations among them. The researchers will soon make the results of their scans available, on a website, to other scientists who are pursuing this line of research. ...

Risk of lymphoma increases with hepatitis C virus infection

...is is one of the largest studies ever conducted to look at the relationship between hepatitis C virus infection and cancers of the lymphatic system," said NCI Director John E. Niederhuber, M.D. "Since so much is still unknown about the causes of lymphoma, establishing which factors contribute to the dise...

Automatic identification of protein's critical features from the structure

How we look is of the greatest importance nowadays since it express who we are, but is it really possible to tell the essence of an individual from its form? The answer to that question seems to be related to fashion and glamour, yet a group of scientists from t...

HIV survival improves if patients stay in care

...o pay for care, enabling him and his colleagues to look at care alone. Giordano and his colleagues look... them to stay in care," said Giordano. He plans to look for ways to intervene in this process. He is now studying a group of people who are newly diagnosed ...

DNA-damage test could aid drug development

...erent conditions," Samson says. "You'll be able to look in more detail at different doses given at different times in the cell differentiation process." "This is a much cheaper assay that's at least as predictive as previous assays," emphasizes Griffith, "and drug developers can afford to use it a lot ...

Chemical maps hint at drug's effects on schizophrenia

Spreading viruses as we breathe

... viruses spread from human expiration means we can look to better design spaces, ventilation systems and filters," she said. Professor Morawska said the next stage of the research would investigate the global effect of dried droplets in health care facilities to see how viruses were spread around the w...

Herpes infection may be symbiotic, help beat back some bacteria

...'s lifetime. "Our results suggest that we should look at whether humans receive similar advantages from these and other chronic infections that do not cause active disease," says senior author Herbert W. "Skip" Virgin, M.D., Ph.D., head of the Department of Pathology and Immunology. "If so, that has pub...

Decoding protein structures helps illuminate cause of diabetes

...low us to probe the molecular structures, but also look at how the structures change in time." Zanni's research group uses a method, known as two-dimensional infrared spectroscopy (2-D IR for short), that takes advantage of the restless nature of molecules and atoms. Though often depicted as static b...

Iowa State scientists demonstrate first use of nanotechnology to enter plant cells

...a chemical we could use that made the nanoparticle look yummy to the plant cells so they would swallow the particles," Torney said. It worked. The nanoparticles were swallowed by the plant protoplasts, which are a type of spherical plant cells without cell walls. Most plant transformation, however...

Scientists seek useful traits in wild cottons

...molecular breeders more tools to work with as they look for ways to diversify, improve and expand our cotton gene pool. That will benefit global breeding stocks and lead to varieties that are more flexible and productive."...
