The 239th National Meeting of the American Chemical Society features a comprehensive series of scientific reports on advances in sustainable development, including the application of green chemistry to reduce hazardous substances. The event aims to shepherd scientists' collective knowledge to address the world's sustainability challenges.
Researchers demonstrate targeted nanoparticle delivery of siRNA to cancer cells, turning off an important gene using RNA interference. The study opens the door for future genetic therapies that can attack cancer and other diseases at a molecular level.
The spliceosome, a giant complex of RNA and protein subunits, assembles and operates to remove unwanted genetic material and join the remaining pieces. Researchers spied on the process using FRET and observed reversible contortions in the presence of energy.
University of Rhode Island researcher Navindra Seeram has discovered over 20 compounds in pure maple syrup with potential health benefits, including anti-cancer and anti-diabetic properties. The research found that these compounds are also present in the Acer family for the first time.
A recent study found that genetic variations in the GPC5 gene are associated with an increased risk of lung cancer in never-smokers. The research, published in The Lancet Oncology, suggests that GPC5 could be a new target for drug development and could help identify high-risk individuals.
A new three-in-one test can detect Chagas' disease, leishmaniasis, and sleeping sickness in under an hour. The low-cost test uses special dyes that reveal the presence of parasite markers.
Newcastle University researchers found that dietary fibre in seaweed reduces fat absorption by 75%. Adding this fibre to foods like bread may help people lose weight while eating normally. The study's next step is to test the effects on volunteers and determine if such foods are acceptable in a normal diet.
Astronomers have observed a galaxy 10 billion light-years away, finding four discrete star-forming regions making new stars 250 times faster than the Milky Way. The study reveals exquisite detail of these regions, which are 100 times brighter than nearby galaxies.
A study by University of Warwick and Cardiff University found that money's impact on happiness is linked to social rank, not income level. Being richer than others is key to life satisfaction.
Scientists at Duke University Medical Center have discovered a new growth factor that stimulates the expansion and regeneration of hematopoietic stem cells. The growth factor, pleiotrophin, has been shown to increase the numbers of human cord blood stem cells in culture capable of engraftment in immune-deficient mice.
The University of Copenhagen is set to establish a leading international research center for basic metabolic research, thanks to a historic $160 million donation from the Novo Nordisk Foundation. The Center will conduct research into Type 2 diabetes and other lifestyle diseases, aiming to make a significant impact on global health trends.
The American Chemical Society symposium on cold fusion has brought together nearly 50 presentations on the topic, indicating that it may be a reality. Researchers are making progress toward battery-based energy and discovering natural occurrences of cold fusion in certain bacteria.
Red and pink coral are in steep decline due to overharvesting; governments failed to grant trade protection despite scientific evidence. Conservationists urge the jewelry and design industries to act where governments have failed.
Researchers at Albert Einstein College of Medicine have found two novel ways to kill TB bacteria, using an enzyme called GlgE and a second pathway that also synthesizes alpha glucans. This combination could lead to a potent therapy that prevents resistant TB strains from developing.
Research found that dark-roasted coffee, including espresso and French roast, may be less irritating to the stomach due to its high content of N-methylpyridium (NMP), a substance that reduces acid production. This discovery could lead to new, stomach-friendly brews with the rich taste and aroma of regular coffee.
Researchers develop a method to determine wine vintages using radioactive carbon dioxide produced by atomic bomb tests. The technique uses accelerator mass spectrometry to analyze the carbon-14 levels in wine alcohol, allowing for reliable detection of vintage authenticity.
A massive galaxy in the early Universe created stars like our sun at a rate equivalent to 250 suns per year, researchers say. The team observed four star-forming regions within the galaxy, each over 100 times brighter than similar regions in the Milky Way.
Researchers have made direct measurements of the size and brightness of regions of star-birth in a very distant galaxy using the APEX telescope. The galaxy is so bright due to massive dust grains heated by starlight, revealing star formation at a rate equivalent to about 250 Suns per year.
Researchers discover the 'doublesex' gene plays a crucial role in shaping fruit fly brain architecture and behavior, leading to distinct male and female neural circuits. The study sheds light on sex determination and coordination of sex-specific physiology in fruit flies.
A recent study found that approximately 30% of never-smoking lung cancer patients carry a rare variant of the GPC5 gene, leading to reduced expression levels and increased risk of cancer. The research suggests that GPC5 may be a critical tumor suppressor gene in lung cancer development.
A new bio-based intelligent roof coating, developed from waste cooking oil, can automatically switch between reflecting and transmitting solar heat to reduce energy costs. The coating, tested on asphalt shingles, showed significant reductions in roof temperatures and potential savings in energy bills.
