Surprising Discovery: Multicellular Response Is 'All For One'It has been widely assumed that, in single-celled organisms, each cell perceives its environment -- and responds to stress conditions -- individually. Likewise, it had been thought that cells in multicellular organisms respond the same way, but scientists have now discovered otherwise. In studies of the worm C. elegans, they found that authority is taken away from individual cells and given to two specialized neurons to sense temperature stress and organize an integrated molecular response for the entire organism.Diet High In Saturated Fat Contributes To Prostate Cancer Treatment Failure, ...Men who consumed high saturated fat diets (HSF) were younger and had higher BMIs at diagnosis than men with who consumed low saturated fat diets (LSF). Saturated fats were most commonly consumed as beef steaks, cheese and cheese spreads, hamburgers and cheeseburgers, eggs, ice cream and salad dressings.Biological Weapons To Control Cane Toad Invasion In AustraliaNew research on cane toads in Northern Australia has discovered a way to control the cane toad invasion using parasites and toad communication signals. Biologists says that controlling toads has been difficult as things that kill them will often kill frogs. Professor Shine and his team studied cane toads in Queensland that lagged behind the invasion front and found they were infected with a lungworm parasite which slows down adults and, in laboratory tests, kills around 30% of baby toads.Previously Unseen Switch Regulates Breast Cancer Response To EstrogenA tiny modification called methylation on estrogen receptors prolongs the life of these growth-driving molecules in breast cancer cells. Most breast cancers contain estrogen receptors, which enable them to grow in the presence of the hormone estrogen. Their presence can determine whether tumors will respond to the estrogen-blocking drug tamoxifen. The finding will help researchers sort out how mutations change the estrogen receptor's function and allow some breast cancers to resist tamoxifen.NASA Successfully Completes First Series Of Ares Engine TestsNASA engineers Thursday successfully completed the first series of tests in the early development of the J-2X engine that will power the upper stages of the Ares I and Ares V rockets, key components of NASA's Constellation Program. Ares I will launch the Orion spacecraft that will take astronauts to the International Space Station and then to the moon by 2020. The Ares V will carry cargo and components into orbit for trips to the moon and later to Mars.Teen 'Self Medication' For Depression Leads To More Serious Mental Illness, N...Millions of American teens report experiencing weeks of hopelessness and loss of interest in normal daily activities and many of these depressed teens are using marijuana and other drugs, making their situation worse, according to a new White House report.Justice In The Brain: Equity And Efficiency Are Encoded DifferentlyWhich is better, giving more food to a few hungry people or letting some food go to waste so that everyone gets a share? A study appearing in Science finds that most people choose the latter, and that the brain responds in unique ways to inefficiency and inequity. |
