New method makes culture of complex tissue possible in any lab
Scientists at the University of California, San Diego have developed a new method for making scaffolds for culturing tissue in three-dimensional arrangements that mimic those in the body. This advance, published online in the journal Advanced Materials, allows the production of tissue culture scaffolds containing multiple structurally and chemically distinct layers using common laboratory reagents...
New prenatal genetic test is much more powerful at detecting fetal abnormalities
A nationwide, federally funded study has found that testing a developing fetus' DNA through chromosomal microarray provides more information about potential disorders than does the standard method of prenatal testing, which is to visually examine the chromosomes. The results of the 4,000-plus-participant clinical study are being presented at the 32nd annual meeting of the Society for...
New research shows C-section not always best for babies
New research challenges conventional wisdom that c-sections have few or no risks for the baby. The findings presented at the 32nd Annual Society for Maternal-Fetal Medicine Meeting, "The Pregnancy Meeting," are consistent with the March of Dimes effort to end medically unnecessary deliveries before 39 weeks of pregnancy. The study is the ninth by SMFM members to be honored by the March of Dimes...
New technology platform for molecule-based electronics
Researchers at the Nano-Science Center at the University of Copenhagen have developed a new nanotechnology platform for the development of molecule-based electronic components using the wonder material graphene.
News of plaque-clearing drug tops week of major advances against Alzheimer's disease
In the last eight days, scientists have delivered a powerful one-two punch in the fight to defeat Alzheimer's disease. At the same time, the White House and members of Congress are proposing increases in Alzheimer's research funding. This has been a big week for all who seek to end this disease, says the CEO of the American Health Assistance Foundation.
NFC aid for the visually and hearing impaired
As the proportion of senior citizens grows, their special needs are gaining momentum. Human eyesight, for example, weakens with age. VTT Technical Research Centre of Finland has been developing new NFC-based applications that make life easier for the visually impaired. A group of affected persons recently tested an innovative, speech-based item identification system and new "talking" packaging...
Obesity is associated with altered brain function
Researchers at the University of Turku and Aalto University have found new evidence for the role of the brain in obesity.
Ocean microbe communities changing, but long-term environmental impact is unclear
As oceans warm due to climate change, water layers will mix less and affect the microbes and plankton that pump carbon out of the atmosphere - but researchers say it's still unclear whether these processes will further increase global warming or decrease it. It could be either, they say.
Ocean warming causes elephant seals to dive deeper
Global warming is having an effect on the dive behavior and search for food of southern elephant seals.
Physically abused children report higher levels of psychosomatic symptoms
Children who display multiple psychosomatic symptoms, such as regular aches and pains and sleep and appetite problems, are more than twice as likely to be experiencing physical abuse at home than children who do not display symptoms. Researchers who studied 2,510 children found a strong association between reported physical abuse and three or more psychosomatic symptoms. The association was...
Potential for incorrect relationship identification in new forensic familial searching techniques
In familial searching, a partial genetic profile match between a database entrant and a crime scene sample is used to implicate genetic relatives of the database entrant as potential sources of the sample. Unlike traditional forensic DNA identification, where all genetic markers must match exactly, in familial searching a portion of genetic markers need to match to suggest a biological...
Potentially important new mechanisms found anti-aging effects of resveratrol
A well-conducted experimental study in mice has provided potentially important new insights into the association of the intake of resveratrol and like compounds with health benefits.
Racial disparities exist in access to kidney transplantation
A new study published in the American Journal of Transplantation reveals that racial disparities exist in both the early and late steps in access to kidney transplantation. This study is part of the February special themed issue of the journal on racial disparity.
Research finds ways that young couples experience less relationship stress, higher satisfaction
Young adults who easily engage in rewarding conversations with their partners are less likely to hold onto anger and stress and more likely to be satisfied with the relationship, according to research from Kansas State University. Researchers are also looking at factors that relate to positive dating relationships or problematic relationships.
Researchers find important 'target' playing role in tobacco-related lung cancers
Researchers at Moffitt Cancer Center in Tampa, Fla., have discovered that the immune response regulator IKBKE (serine/threonine kinase) plays two roles in tobacco-related non-small cell lung cancers. Tobacco carcinogens induce IKBKE and, in turn, IKBKE induces chemotherapy resistance.
Scripps research scientists identify most lethal known species of prion protein
Scientists from the Florida campus of the Scripps Research Institute have identified a single prion protein that causes neuronal death similar to that seen in "mad cow" disease, but is at least 10 times more lethal than larger prion species.
Secrets of immune response illuminated in new study
In research appearing in this month's issue of the journal Nature Immunology, Roy Curtiss, director of the Center for Infectious Diseases and Vaccinology at the Biodesign Institute at Arizona State University investigates the coordination of a particular type of immune response, involving the release of of IFN-λ -- a cell-signaling protein molecule known as a cytokine.
