Rapid response was crucial to containing the 1918 flu pandemic

...hit cities like Philadelphia when both implemented similar public health measures? What made the difference, ...ses. Philadelphia, New Orleans and Boston all used similar interventions, but they took longer to implement them, and as a result, peak mortality rates were hi...

Scientists identify pancreatic cancer stem cells

...genic pancreatic cancer cells "appeared remarkably similar to the appearance of tumors taken directly from patients," Simeone said. The purported cancer stem cells produced a diverse mixture of cells, some of which are not cancerous, that reflected an actual human pancreatic tumor, she said. The markers t...

2 brains -- 1 thought

...parable pattern of neural activity when exposed to similar sensory input. Scientists at the Max Planck Institute for Dynamics and Self-Organization in Göttingen have now developed a mathematical method to design networks from neural cells which exhibit a predefined pattern dynamics. The researchers hope that...

Out-of-body experiences may be caused by arousal system disturbances in brain

...are outside of your body and watching yourself?" A similar question was posed to survey out-of-body experiences during near death, which asked subjects if during their experience they had "clearly left the body and existed outside it." Because the arousal system controls or influences sleep-wake states, a...

UCI scientists reconstruct migration of avian flu virus

...s parallel evolution ?the independent evolution of similar traits ?enables H5N1 to spread quickly, the scientists believe. "The ability to develop the right mutation allows the virus to hop from one host type to the next," said Robert Wallace, UCI postdoctoral researcher and lead author of the study. "By ...

Study suggests some drug resistance to influenza B medications

...gence of oseltamivir-resistant type A viruses, but similar information on influenza B viruses has been limited. Influenza B viruses are associated with annual outbreaks of illness and increased death rates worldwide, according to background information in the article. Shuji Hatakeyama, M.D., Ph.D., of th...

Gut research yields new anti-cancer approach

... the paper. "Because cells that line the colon are similar to those in the liver, esophagus and skin, we see potential for a new way to treat those cancers as well." In the study that led to the discovery of the anti-cancer effect, researchers were looking for new ways to reduce inflammation seen in Crohn...

Row over study puts Korea's scientific community under scrutiny again

...e turned to shock when, in December 2005, he saw a similar paper in Fertility and Sterility. He was even more shocked to see that the number of authors had reduced to six and that he was no longer one of them. The lead author was Dr Cha. In December last year, Dr Kim filed a lawsuit in Korea against Dr Ch...

"Action video game play changes the way our brains process visual information," says Daphne Bavelier, professor of b...

Researchers identify gene involved in dog size

...und the IGF-1 gene in 463 Portuguese water dogs. A similar analysis was done using 526 dogs from 14 small breeds and nine giant dog breeds. Ultimately, the researchers analyzed DNA from more than 3,000 dogs from 143 breeds to pinpoint a specific gene sequence variant, or haplotype, associated with small ...

Researchers learn what sparks plant growth

...ults also show that these hormones act locally. As similar studies are done for other plant hormones and in other organs, such as the root, we will know the major sites of action of each plant hormone and will be able to make models to predict how they work together to give rise to the tremendous diversity o...

Scripps research study shows humans and plants share common regulatory pathway

...ted the study. "Plants have Nod-like receptors and similar immune responses to bacteria and other pathogens-the R proteins evolved to counteract these pathogenic effects. Our study provides a new perspective on the Nod1 pathway in mammalian cells as well as the value of drawing on plant studies of R protein ...

New compound prevents alcoholic behavior, relapse in animals by blocking stress response

...levels can be especially high. The compound or similar molecules can be given orally, reach the brain in sufficient amounts to block more than 90 percent of certain brain CRF receptors, and do not accumulate in other organs, most importantly the liver, in ways that would cause concerns about potential si...

The penalty of having a sister -- why sibling sex matters for male saiga antelopes

...supermums of the hoofed animal world with no other similar species investing more in their offspring during pregnancy. The study's results call into question current understanding of the development of male and female foetuses of this species, and give scientists a new insight into the importance of sibli...

Compared to similar people without cancer, cancer patients' net time associated with medical care varied, ranging from 17.8 hours for melanoma to 351.3 hours for gastric cancer and 368.1 hours for ovarian cancer. When the researchers applied the dollar costs to time spe...

Bypassing eggs, flu vaccine grown in insect cells shows promise
