Our desire for indulgent meals may be over 500 years old. A new analysis of European and American paintings across five centuries shows that salt, bread, sausage, and shellfish were among the most commonly depicted foods in paintings of meals from 1500 to 2000 AD.
In a surprise finding, researchers working with breast cancer cells purchased at the same time from the same cell bank discovered that the cells responded differently to chemicals, even though the researchers had not detected any difference when they tested them for authenticity at the time of purchase.
In a recent study, researchers show that sex hormones can stimulate production of telomerase, an enzyme naturally found in the human organism. The strategy was tested in patients with genetic diseases associated with mutations in the gene that codes for this enzyme, such as aplastic anemia and pulmonary fibrosis. The authors say that the results suggest that the approach can combat the damage caused to the organism by telomerase deficiency.
Volcanic climate perturbations that delivered cold and stormy weather to much of the Northern Hemisphere generated a combination of conditions in the Sonoran Desert that were just right for vulnerable young saguaro cacti. Biogeographer Taly Drezner will present her research on Aug. 9, 2016 at the 101st Annual Meeting of the Ecological Society of America, in Fort Lauderdale, Florida.
Investigators at the Medical University of South Carolina and Ralph H. Johnson VA Medical Center report clinical research showing that African-American and European-American men with prostate cancer exhibit significantly different expression of genes associated with immune response and inflammation, in the July 2016 issue of Pharmacogenomics. Systems-level, RNA analyses support the concept that inflammatory processes may contribute to racial disparities in disease progression and that vitamin D3 supplementation can modulate pro-inflammatory transcripts.
A new study from a researcher at the University of Notre Dame comparing mouse and macaque brains has found evidence of an evolutionary universal brain structure in mammals that could provide insights into brain disorders such as Alzheimer's and schizophrenia.
Polar oceans pump organic carbon down to the deep sea about five times as efficiently as subtropical waters, because they can support larger, heavier organisms.
The creation of a new polymer morphology in a material called PLA could lead to better medical implants and drug-delivery devices.
Variations in a gene with multiple functions in neurons are present in approximately 3 percent of all cases of ALS in North American and European populations, both sporadic and familial, making it one of the most common genetic causes of the disease, according to a paper published in Nature Genetics.
In a series of experiments at the University at Buffalo, the embryonic stem cell gene Nanog kicked into action dormant cellular processes that are key to preventing weak bones, clogged arteries and other telltale signs of growing old.
