Printable, electrically conductive gel with unprecedented electrical performance synthesized Posted: 04 Jul 2012 03:25 PM PDT Researchers have invented an electrically conductive gel that is quick and easy to make, can be patterned onto surfaces with an inkjet printer and demonstrates unprecedented electrical performance.

Sequencing of fetal genomes using only maternal blood sample Posted: 04 Jul 2012 03:21 PM PDT Researchers have for the first time sequenced the genome of an unborn baby using only a blood sample from the mother. The new technique hinges on the fact that pregnant women have DNA from both their cells and the cells of their fetus circulating freely in their blood.

Urban athletes show that for orangutans, it pays to sway Posted: 04 Jul 2012 09:43 AM PDT Swaying trees is the way to go, if you are a primate crossing the jungle. Using human street athletes as stand-ins for orangutans, researchers have measured the energy required to navigate a forest using different strategies and found it pays to stay up in the trees.

Seabirds study shows plastic pollution reaching surprising levels off coast of Pacific Northwest Posted: 04 Jul 2012 09:43 AM PDT Plastic pollution off the northwest coast of North America is reaching the level of the notoriously polluted North Sea, according to a new study.

Fertility preservation with cryopreservation of ovarian tissue: From experimental to mainstream Posted: 04 Jul 2012 09:43 AM PDT Although the first successful preservation of fertility from the freezing, thawing and grafting of ovarian tissue was reported eight years ago, the technique has remained experimental and confined to a few specialist centers. Now, with the announcement of a first pregnancy (and subsequent live birth) in Italy following the transplantation of ovarian tissue, there are indications that fertility preservation is moving into the mainstream of reproductive medicine and into a greater number of centers.

Single embryo transfer reduces the risk of perinatal mortality in IVF Posted: 04 Jul 2012 09:43 AM PDT A policy of single embryo transfer (SET) reduces the risk of perinatal mortality in infants born as a result of IVF and ICSI. The conclusion emerged from an analysis of more than 50,000 births recorded in the Australian and New Zealand Assisted Reproduction Technology Database between 2004 and 2008, where the introduction of an SET policy has been associated with a reduction in overall perinatal mortality for IVF and ICSI babies.

Development of antibiotic resistance more predictable than expected Posted: 04 Jul 2012 09:41 AM PDT Research has shown that the development of bacteria with resistance against the antibiotic cefotaxime occurs more often and more predictably than was previously assumed. Bacterial populations were found to have many mutations that increase resistance and therefore have a negative effect on public health. Moreover, the effects are such that it can be predicted that the development of bacterial strains with a resistance against cefotaxime will progress in a similar way in different patients from different locations.

Humidity increases odor perception in terrestrial hermit crabs Posted: 04 Jul 2012 09:41 AM PDT Olfaction in land crabs is still in an early transitional stage between life in water and on land.

Calcium carbonate templates for drug delivery Posted: 04 Jul 2012 09:40 AM PDT The fast and targeted delivery of drugs could soon be made easier. Microcontainers for medical substances can be produced in different sizes using calcium carbonate microspheres as templates, new research shows.

Molecule changes magnetism and conductance Posted: 04 Jul 2012 09:40 AM PDT One bit of digital information stored on a hard disk currently consists of about 3 million magnetic atoms. Researchers have now developed a magnetic memory with one bit per molecule. By an electric pulse, the metal-organic molecule can be switched reliably between a conductive, magnetic state and a low-conductive, non-magnetic state.

Extreme weather conditions cost EU’s transport system at least €15 billion annually Posted: 04 Jul 2012 09:40 AM PDT Extreme weather conditions cost EU's transport system at least €15 billion annually. Currently, the greatest costs incurred are from road accidents, with the associated material damage and psychological suffering.

CERN experiments observe particle consistent with long-sought Higgs boson Posted: 04 Jul 2012 08:22 AM PDT Physicists with the the ATLAS and CMS experiments have presented their latest preliminary results in the search for the long-sought Higgs particle. Both experiments observe a new particle in the mass region around 125-126 GeV.

New method knocks out stubborn electron problem Posted: 03 Jul 2012 11:18 PM PDT A newly published article eliminates one of the top unsolved theoretical problems in chemical physics as ranked by the National Research Council in 1995. Scientists now can more accurately predict the dynamic behavior of electrons in atoms and molecules in chemical reactions that govern a wide range of phenomena, including the fuel efficiency of combustion engines and the depletion of the atmospheric ozone.

How cooperation can trump competition in monkeys Posted: 03 Jul 2012 11:18 PM PDT Being the top dog -- or, in this case, the top gelada monkey -- is even better if the alpha male is willing to concede at times to subordinates, according to a new study. Alpha male geladas who allowed subordinate competitors into their group had a longer tenure as leader, resulting in an average of three more offspring each during their lifetimes.

New drug prospect offers hope against hookworm infections Posted: 03 Jul 2012 11:18 PM PDT A drug candidate that is nearing clinical trials against a Latin American parasite is showing additional promise as a cure for hookworm, one of the most widespread and insidious parasites afflicting developing nations.

Pre-industrial emissions still causing temperatures to rise Posted: 03 Jul 2012 11:17 PM PDT When evaluating the historic contributions made by different countries to the greenhouse gasses found in Earth's atmosphere, calculations generally go back no further than the year 1840. New research shows that carbon dioxide contributions from the pre-industrial era still have an impact on our climate today.

Brazil has laws that protect against 'Big Food' and 'Big Snack' Posted: 03 Jul 2012 11:17 PM PDT Under pressure from civil society organizations, the Brazilian government has introduced legislation to protect and improve its traditional food system, standing in contrast to the governments of many industrialized countries that have partly surrendered their prime duty to protect public health to transnational food companies, argue nutrition and public health experts.

Shrinking leaves point to climate change Posted: 03 Jul 2012 11:15 PM PDT Rcent climate change is causing leaves of some Australian plants to narrow in size.
