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.

A new particle has been discovered -- chances are, it is the Higgs boson Posted: 04 Jul 2012 09:43 AM PDT The long and complicated journey to detect the Higgs boson, which started with one small step about 25 years ago, might finally have reached its goal. This was reported by LHC particle accelerator scientists today (July 4, 2012) at the European Laboratory for Particle Physics, CERN, near Geneva. The Higgs boson is the final building block that has been missing from the "Standard Model," which describes the structure of matter in the universe. The Higgs boson combines two forces of nature and shows that they are, in fact, different aspects of a more fundamental force. The particle is also responsible for the existence of mass in the elementary particles.

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.

Freezing all embryos in IVF with transfer in a later non-stimulated cycle may improve outcome Posted: 04 Jul 2012 09:43 AM PDT There is growing interest in a "freeze-all" embryo policy in IVF. Such an approach, which cryopreserves all embryos generated in a stimulated IVF cycle for later transfer in a non-stimulated natural cycle, would avoid any of the adverse effects which ovarian stimulation might have on endometrial receptivity during the treatment cycle.

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.

Game, set and match to strawberries: The superfruit Posted: 04 Jul 2012 09:41 AM PDT Strawberries, the traditional summer treat associated with Wimbledon could be serving up some unexpected health benefits.

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.

Toward an alternative for antibiotics to fight bacterial infections? Posted: 04 Jul 2012 09:41 AM PDT Mice that do not produce the receptor protein NLRP6, are better protected against bacterial infections and can more easily remove bacteria from the body. Therapeutic drugs that neutralize NLRP6 could be a possible treatment option, in addition to the use of antibiotics, for fighting bacterial infections.

Scientific study reveals that individuals cooperate according to their emotional state and their prior experiences Posted: 04 Jul 2012 09:40 AM PDT When deciding whether to cooperate with others, people do not act thinking of their own reward, as had been previously believed, but rather individuals are more influenced by their own mood at the time and by the number of individuals with whom they have cooperated before.

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.

No show stoppers for concentrating solar power Posted: 04 Jul 2012 09:40 AM PDT Solar thermal power is largely unrestricted by materials availability. There are, however, some issues that the industry needs to look into soon, like replacing silver in mirrors.

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.

Voyage of discovery sights what could be the Higgs: Canadians key part of historical science breakthrough Posted: 04 Jul 2012 08:57 AM PDT Early this morning (July 4, 2012), the ATLAS and CMS particle-physics experiments at the LHC accelerator at CERN presented their latest results in the hunt for the Higgs boson with thousands of viewers from around the world at a global press conference in Geneva, Switzerland. Both experiments observe a new particle in the mass region around 125-126 GeV consistent with the Higgs. Across Canada, hundreds have played critical roles in this breakthrough and are now celebrating.

Search for Higgs boson at Large Hadron Collider reveals new particle Posted: 04 Jul 2012 08:50 AM PDT Physicists on experiments at the Large Hadron Collider announced today (July 4, 2012) that they have observed a new particle. Whether the particle has the properties of the predicted Higgs boson remains to be seen.

Statement from CMS: Observation of a new particle with a mass of 125 GeV Posted: 04 Jul 2012 08:39 AM PDT Researchers with the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) have presented their preliminary results on the search for the standard model (SM) Higgs boson. CMS observes an excess of events at a mass of approximately 125 GeV with a statistical significance of five standard deviations (5 sigma) above background expectations. The probability of the background alone fluctuating up by this amount or more is about one in three million. The evidence is strongest in the two final states with the best mass resolution: first the two-photon final state and second the final state with two pairs of charged leptons (electrons or muons). The scientists interpret this to be due to the production of a previously unobserved particle with a mass of around 125 GeV.

Latest results from ATLAS Higgs search Posted: 04 Jul 2012 08:28 AM PDT On July 4, 2012, the ATLAS experiment presented a preview of its updated results on the search for the Higgs Boson. The results were shown at a seminar held jointly at CERN and via video link at ICHEP, the International Conference for High Energy Physics in Melbourne, Australia, where detailed analyses will be presented later this week. At CERN, preliminary results were presented to scientists on site and via webcast to their colleagues located in hundreds of institutions around the world.

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.

Rate of community-onset MRSA infections appears to be on the decline Posted: 03 Jul 2012 11:17 PM PDT In analysis that included more than 9 million US Department of Defense nonactive and active duty personnel, the rates of both community-onset and hospital-onset methicillin-resistant Staphylococcus aureus (MRSA) bacteremia decreased from 2005 to 2010, while the proportion of community-onset skin and soft tissue infections due to MRSA has more recently declined, according to a new study.

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.

Potential food crisis with global warming, UK scientists warn Posted: 03 Jul 2012 11:15 PM PDT UK consumers could face dramatically reduced food choices in the future unless much more is done to cut greenhouse gas emissions, a hard-hitting report warns. Food which families now take for granted, such as meat and fresh vegetables, could become too expensive for many if global temperatures rise in line with the current trends and reach 4°C within the lifetime of many people.

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.

Heat wave especially dangerous for kids Posted: 03 Jul 2012 05:05 PM PDT Extreme heat continues to plague the nation with many areas seeing record temperatures. Though everyone needs to take precautions when it comes to dangerous heat, it's especially important to watch your kids. Children are at a greater risk than adults of sustaining a heat injury.
