Increasing temperatures at high altitudes are fueling the post-1950 growth spurt seen in bristlecone pines, the world's oldest trees, according to new research.
According to a team of the worldâ€™s leading scientists, some of the plans slated for discussion and potential enactment into international law at the much-anticipated UN Copenhagen climate conference this winter could eventually damage the environment as much as they help save it.
Recording hundreds of thousands of individual uplinks from satellite transmitters fitted on penguins, albatrosses, sea lions, and other marine animals, the Wildlife Conservation Society (WCS) and BirdLife International have released the first-ever atlas of the Patagonian Sea â€“ a globally important but poorly understood South American marine ecosystem.
An accidental discovery in a laboratory at Oregon State University has apparently solved a quest that over thousands of years has absorbed the energies of ancient Egyptians, the Han dynasty in China, Mayan cultures and more â€“ the creation of a near-perfect blue pigment.
UCI computer model foresees effects of alternative transportation fuels.
Scientists at the John Innes Centre in Norwich, UK, have shown how plants can protect themselves against genetic damage caused by environmental stresses.
Researchers from Arizona State University have discovered that several species of microbes (cyanobacteria), at least one found prominently in the deserts of the Southwest, have evolved the trait of rope-building to lasso shifting soil substrates.
New tool for research mathematics on the 150th anniversary of the Riemann Hypothesis.
Biologists at UC San Diego have discovered that honeybees can discriminate between food at different temperatures, an ability that may assist bees in locating the warm, sugar-rich nectar or high-protein pollen produced by many flowers.
Many biological processes are controlled by small molecules known as microRNAs, which work by suppressing the expression of specific sets of genes.
- The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
