In our everyday life, we use gasoline, diesel, plastics, rubbers, and numerous chemicals that are derived from fossil oil through petrochemical refinery processes. Fossil resources are limited and not sustainable. Our world is facing problems associated with climate change and other environmental problems resulted from lavish consumption of fossil fuels.

It has been known for years that eating too many foods containing "bad" fats, such as saturated fats or trans fats, isn't healthy for your heart. However, according to new research from Brigham and Women's Hospital (BWH), one "bad" fat—saturated fat—was found to be associated with worse overall cognitive function and memory in women over time. By contrast, a "good" fat—mono-unsaturated

The strategy used by Google to decide which pages are relevant for a search query can also be used to determine which proteins in a patient's cancer are relevant for the disease progression. Researchers from Dresden University of Technology, Germany, have used a modified version of Google's PageRank algorithm to rank about 20,000 proteins by their genetic relevance to the progression of pancreatic

There are always exceptions to a rule, even one that has prevailed for more than three decades, as demonstrated by a Cold Spring Harbor Laboratory (CSHL) study on RNA splicing, a cellular editing process. The rule-flaunting exception uncovered by the study concerns the way in which a newly produced RNA molecule is cut and pasted at precise locations called splice sites b

How species diversity is maintained is a fundamental question in biology. In a new study, a team of Indiana University biologists has shown for the first time that diversity is influenced on a spatial scale of unparalleled scope, in part, by how well tree seedlings survive under their own parents.

A McGill-led research team using the Herschel Space Observatory has discovered a giant, galaxy-packed filament ablaze with billions of new stars. The filament connects two clusters of galaxies that, along with a third cluster, will smash together and give rise to one of the largest galaxy superclusters in the universe.

One-letter switches in the DNA code occur much more frequently in human genomes than anticipated, but are often only found in one or a few individuals.

An international team of researchers has discovered how adding trace amounts of water can tremendously speed up chemical reactions—such as hydrogenation and hydrogenolysis—in which hydrogen is one of the reactants, or starting materials.

Across history and cultures, religion increases trust within groups but also may increase conflict with other groups, according to an article in a special issue of Science.

Innate differences in immunity can be detected at birth, according to new research at Washington University School of Medicine in St. Louis. And babies with a better innate response to viruses have fewer respiratory illnesses in the first year of life.
