| Scientists find possible solution to an ancient enigma  | The widespread disappearance of stromatolites, the earliest visible manifestation of life on Earth, may have been driven by single-celled organisms called foraminifera, study finds. | Read More »  Shape-shifting nanoparticles flip from sphere to net in response to tumor signal  | Tiny spherical particles float easily through the bloodstream after injection, then assemble into a durable scaffold within diseased tissue. An enzyme produced by a specific type of tumor can trigger the transformation of the spheres into netlike structures that accumulate at the site of a cancer. | Read More » Preventing 'traffic jams' in brain cells  | An Alzheimer's disease protein controls the speed at which materials move through brain cells, and defects could lead to deadly pileups of the kind seen in neurodegenerative disease, a new publication finds. | Read More » Historic sea-level change along New Jersey coastline mapped  | A new study relied upon fossil records of marshland to reconstruct the changes in sea level along the New Jersey coast going back 10,000 years. | Read More » Rare species perform unique roles, even in diverse ecosystems  | A new study reveals the potential importance of rare species in the functioning of highly diverse ecosystems. Using data from three different ecosystems -- coral reefs, tropical forests and alpine meadows -- a team of researchers has shown that it's primarily the rare species, rather than more common ones, that have distinct traits involved in unique ecological functions. As biodiversity declines, these unique features are particularly vulnerable to extinction because rare species are likely to disappear first. | Read More » Small molecule could have big impact on cancer  | Researchers have designed and synthesized a novel small molecule that might become a large weapon in the fight against prostate cancer. | Read More » Childhood abuse linked with food addiction in adult women  | Women who experienced severe physical or sexual abuse during childhood are much more likely to have a food addiction as adults than women who did not experience such abuse, according to a new study. The study's findings provide valuable new information regarding potential causes and treatments for food addiction and obesity. | Read More » Nanomedicines' impact on patients under the microscope  | A pioneering imaging technique to track the effects of next-generation nanomedicines on patients has now been harnessed. | Read More » Klein tunneling: Coupled particles cross energy wall  | A new model demonstrates that it is possible for two particles to cross an energy barrier together, where a single particle could not. For the first time, a new kind of so-called Klein tunneling -- representing the quantum equivalent of crossing an energy wall -- has been presented in a model of two interacting particles. | Read More » Despite safety and other concerns, nuclear power saves lives, greenhouse gas emissions, experts say  | Global use of nuclear power has prevented about 1.84 million air pollution-related deaths and release of 64 billion tons of greenhouse gases that would have resulted from burning coal and other fossil fuels, a new study concludes. | Read More » New treatment for stroke set to increase chances of recovery  | Researchers have completed a landmark study which has revealed a new way to treat strokes caused by bleeding inside the brain. | Read More » Immigration status affects educational achievement  | Mexican American mothers' formal immigration status affects the educational achievement of their children and even their grandchildren, according to a new study. | Read More » Twitter may become less interactive and more an advertising broadcast medium like TV or radio  | Popular social media site Twitter may eventually resemble a broadcast medium like television or radio, with users reading messages written by celebrities and corporations rather than writing their own "tweet" messages of up to 140 characters, suggests a new study. | Read More » Recovery of Hawaiian green sea turtles still short of historic levels  | Hawaiian green sea turtle populations have increased in recent years, but their numbers still fall far short of historic levels. A new report suggests that calls to lift protection for this species may be premature. | Read More » Arctic current flowed under deep freeze of last ice age, study says  | During the last ice age, when thick ice covered the Arctic, many scientists assumed that the deep currents below that feed the North Atlantic Ocean and help drive global ocean currents slowed or even stopped. But in a researchers have now shown that the deep Arctic Ocean has been churning briskly for the last 35,000 years, through the chill of the last ice age and warmth of modern times. | Read More » Genetic engineering alters mosquitoes' sense of smell  | In one of the first successful attempts at genetically engineering mosquitoes, researchers have altered the way the insects respond to odors, including the smell of humans and the insect repellant DEET. The research not only demonstrates that mosquitoes can be genetically altered using the latest research techniques, but paves the way to understanding why the insect is so attracted to humans, and how to block that attraction. | Read More » | |
