Whether we are searching the cosmos or probing the subatomic realm, our most successful theories lead to the inescapable conclusion that our universe is just a speck in a vast sea of universes.
Simple, inexpensive measures to cut emissions of two common pollutants will slow global warming, save millions of lives and boost crop production around the world, an international team of scientists. The climate-change debate has centered on carbon dioxide, a gas that wafts in the atmosphere for decades, trapping heat. But in recent years, scienti have…
The universe has no center and no edge, no special regions tucked in among the galaxies and light. No matter where you look, it’s the same—or so physicists thought. This cosmological principle—one of the foundations of the modern understanding of the universe—has come into question recently as astronomers find evidence, subtle but growing, of a…
Former vice president Al Gore posted on his webpage that scientific studies of clouds and atmospheric pressure suggests that, “more likely than not, our planet will experience cataclysmic warming by the end of the century.” That would take mankind to the year 2100 before all hell breaks loose. Gore, who taught the world about the…
The reluctance of industrialized countries to accept binding emission targets will dry up demand for carbon credits and reduce their prices further, experts said at the climate talks in Doha, where 200 countries are trying to negotiate an agreement on climate issues. Russia, Japan, New Zealand have made it clear that they will not accept…
Hanukkah, a festival of light in the darkness of winter, shares much in common with other religions that also emphasize a light motif in overcoming the negative feelings that human beings often associate with extended darkness. The frightening darkness that so many experienced in the aftermath of Sandy, and many are still experiencing, was a…
University of Alaska Fairbanks scientists have identified what they think is the ancestral trait that allowed for the evolution of air breathing in vertebrates. “To breathe air with a lung you need more than a lung, you need neural circuitry that is sensitive to carbon dioxide,” said Michael Harris, lead researcher of a team that…
