crowdsourced game aims to find solutions to aflatoxin




mars, inc., uc davis and partners have launched a crowdsourcing initiative to solve the problem of aflatoxin contamination of crops. a series of aflatoxin puzzles will go online on foldit, a platform that allows gamers to explore how amino acids are folded together to create proteins. the puzzles pr...



mutants in microgravity




bacteria may mutate more rapidly in space and scientists theorize patterns of those mutations could help predict how pathogens become resistant to antibiotics. such predictions could, in turn, be used to develop new drugs to use against those pathogens. antibiotic resistant pathogens or bacteria is ...



scientists work to develop heat-resistant 'cow of the future'




university of florida scientists are working to breed the "cow of the future" by studying the more heat-tolerant brangus cow—a cross between an angus and a brahman.



aflatoxin-free transgenic maize using host-induced gene silencing




when ingested by animals, aflatoxins cause health problems including liver cancer and stunted growth. thakare et al. used host-induced gene silencing (higs) to block aflatoxin production in maize. aflatoxins are toxic metabolites produced by some species of aspergillus fungi that can occur on numer...



moffitt researchers identify inhibitor that overcomes drug resistance in prostat




tampa, fla. (june 12, 2017) - prostate cancer is the third most common cause of cancer-related death in men in the united states. it is estimated that 161,360 men will be diagnosed and more than 26,700 men will die from the disease in this year. the majority of these deaths are caused by prostate ca...



discovery could lead to design of next-generation antibiotics




antibiotic resistance is a growing global health threat. so much so that a 2014 study commissioned by the prime minister of the united kingdom predicted that, if the problem is left unchecked, in less than 35 years more people will die from antibiotic resistant superbugs than from cancer. it is crit...

bacteria from cystic fibrosis patient could help thwart antibiotic-resistant tb




the number of drug-resistant tuberculosis (tb) cases is rising globally. but a newly discovered natural antibiotic -- produced by bacteria from the lung infection in a cystic fibrosis patient -- could help fight these infections. lab testing reported in the journal of the american chemical society s...



new finding could lead to earlier liver cancer diagnosis




image: research scientist bogdan fedeles and postdoc supawadee chawanthayatham have discovered a mutational signature that reveals liver cell exposure to aflatoxin, a potent carcinogen. view more credit: melanie gonick/mitin many parts of the world, including southeast asia and sub-saharan africa, ...

conch shells hold the secret to impact-resistant armor




conch shells have a complex, three-tiered structure with a zigzag matrix that makes them resistant to breakage. small cracks don't typically lead to big ones, since they have to go through a maze to become bigger. however, to be able to replicate that quality, scientists need more data on how exactl...

scientists discover how some pigs cope in cold climates




domestic pig. credit: scott bauer, usdaa new paper in the journal of molecular cell biology revealed that pig breeds such as tibetan pigs and min pigs use a unique method to survive when exposed to cold environments. this has important implications for the swine industry as cold weather is a major c...



scientists expand ability of stem cells to regrow any tissue type




when scientists talk about laboratory stem cells being totipotent or pluripotent, they mean that the cells have the potential, like an embryo, to develop into any type of tissue in the body. what totipotent stem cells can do that pluripotent ones can't do, however, is develop into tissues that suppo...



scientists working toward reversible kind of gene editing

indian rivers teeming with drug resistant bacteria, says report




from the cauvery in karnataka to the yamuna in delhi – big indian rivers are reservoirs of antibiotic resistant bacteria, exposing millions to increased health risks, notes a new government report.multiple studies carried out on cauvery water samples highlighted the seriousness of the problem...



researchers to develop new gene-editing method for the study of arthropods




a grant from the national science foundation will enable a penn state-led team of entomologists to develop and disseminate a technology they say could bring gene-editing capabilities within reach of everyday scientists, regardless of the arthropod species they study.



scientists discover path to improved barley quality




scientists from the international barley hub have discovered a genetic pathway to improved barley grain size and uniformity, a finding which may help breeders develop future varieties suited to the needs of growers and distillers.



scientists develop molecular code for melanin-like materials




scientists have long known that melanin—the pigments that give color to skin, hair and eyes—has numerous useful qualities, including providing protection from cancer-causing uv radiation and free radicals, but also electronic conductance, adhesiveness and the capacity to store energy.
