Preplay: How past experiences subconsciously influence behavior (December 24, 2010) -- Researchers report for the first time how animals' knowledge obtained through past experiences can subconsciously influence their behavior in new situations. ... > full story
Arsenic agent shuts down two hard-to-treat cancers in animal experiments (December 24, 2010) -- Researchers have found that an arsenic-based agent already FDA-approved for a type of leukemia may be helpful in another hard-to-treat cancer, Ewing's Sarcoma (ES). The research, based on animal studies, also suggests the drug might be beneficial in treating medulloblastoma, a highly malignant pediatric brain cancer. ... > full story
Emerging drug class may enhance red blood cell production in anemic patients (December 24, 2010) -- By determining how corticosteroids act to increase production of red blood cell progenitors, researchers have identified a class of drugs that may be beneficial in treating some erythropoietin-resistant anemias. One such anemia is Diamond-Blackfan anemia (DBA), which is frequently treated with corticosteroids, despite their severe side-effects. The identified class of drugs may be able to treat other anemias, including those resulting from trauma, sepsis, malaria, kidney dialysis and chemotherapy. ... > full story
Site in brain where leptin may trigger puberty identified (December 24, 2010) -- Researchers have pinpointed a tiny site in the brain where the hormone leptin may help trigger the onset of puberty. ... > full story
Fast sepsis test can save lives (December 24, 2010) -- Blood poisoning can be fatal. If you suffer from sepsis, you used to have to wait as much as 48 hours for laboratory findings. A new diagnostic platform as big as a credit card will now supply the analysis after as little as an hour. This system is based on nanoparticles that are automatically guided by magnetic forces. ... > full story
Alzheimer's: Tau disrupts neural communication prior to neurodegeneration (December 24, 2010) -- A new study is unraveling the earliest events associated with neurodegenerative diseases characterized by abnormal accumulation of tau protein. The research reveals how tau disrupts neuronal communication at synapses and may help to guide development of therapeutic strategies that precede irreversible neuronal degeneration. ... > full story
You are what your father ate, too: Paternal diet affects lipid metabolizing genes in offspring, research suggests (December 24, 2010) -- We aren't just what we eat; we are what our parents ate, too. That's an emerging idea that is bolstered by a new study showing that mice sired by fathers fed on a low-protein diet show distinct and reproducible changes in the activity of key metabolic genes in their livers. Those changes occurred despite the fact that the fathers never saw their offspring. ... > full story
Protein involved in early steps of melanoma development revealed (December 24, 2010) -- A protein required for early stages of melanoma development can also predict melanoma outcome, according to new research. ... > full story
Designer probiotics could reduce obesity (December 23, 2010) -- Specially designed probiotics can modulate the physiology of host fat cells say scientists. The findings could lead to specialized probiotics that have a role in the prevention or treatment of conditions such as obesity. ... > full story
How cells running on empty trigger fuel recycling (December 23, 2010) -- Researchers have discovered how AMPK, a metabolic master switch that springs into gear when cells run low on energy, revs up a cellular recycling program to free up essential molecular building blocks in times of need. ... > full story
Simple screen can help isolate virulent parts of pathogenic bacteria gene structures (December 23, 2010) -- Researchers have developed a new approach to studying potentially deadly disease-causing bacteria which could help speed up the process of finding vaccines. The scientists have pioneered a simple screen which can help isolate the virulent parts of the gene structures of pathogenic bacteria. The screen allows researchers to simultaneously run thousands of tests where genes from the pathogen are pitted against the human blood cells that normally attack them. ... > full story
Shouldering family demands and worries bumps up angina risk (December 23, 2010) -- Shouldering family demands and worries seems to increase the risk of angina, the precursor to coronary artery disease, reveals new research. ... > full story
