People don’t generally engage in moral reasoning, Haidt argues, but moral rationalization: they begin with the conclusion, coughed up by an unconscious emotion, and then work backward to a plausible justification.

Influential website Edge asked intellectuals including Gregory Benford, Richard Dawkins, Freeman Dyson, Brian Eno and many others the question "How have scientific findings or arguments changed your mind?" Here are their answers. Fascinating stuff.

A Spanish physicist has discovered what appears to be a new law of nature that may help explain, among other things, how life arose out of a primordial soup and why investing in losing stocks can sometimes lead to greater capital gains. Called Parrandos paradox, the law states that two games guaranteed to make a player lose all his money can gen

A set of relatively simple modifications of a high precision microscope lead to faster imaging, measuring the temperature of a single atom, and potentially measuring distances at the edge of what quantum mechanics and the Heisenberg uncertainty principle says is possible.

Silicon electronics has been the staple of the computing industry for more than half a century, but increasingly researchers are looking at other methods of computing to deliver increased computational power or allow specialist applications.

The big world of classical physics mostly seems sensible: waves are waves and particles are particles, and the moon rises whether anyone watches or not. The tiny quantum world is different: particles are waves (and vice versa), and quantum systems remain in a state of multiple possibilities until they are measured --

Using laser light to stir an ultracold gas of atoms, researchers at the National Institute of Standards and Technology (NIST) and the Joint Quantum Institute (NIST/University of Maryland) have demonstrated the first 'persistent' current in an ultracold atomic gas -a frictionless flow of particles.

A satellite experiment to demonstrate a "space mail" system to deliver packages to Earth using a tether deployed the longest space tether ever flown, but "lost" its payload in space. Let's hope the U.S. Pentagon and NASA do better with delivering energy from space via their solar power-beaming satellites.

It seems you don't need a disk to thumb your nose at celestial mechanics - if you're big enough to be a galaxy.Recent investigations of the velocities of stars in dwarf galaxies have reinforced the need for explanatory dark matter to account for their motion.

Evidence is mounting for the existence of a strange new state of matter called a "supersolid", in which a small fraction of ultracold helium decouples from the rest of the solid and flows effortlessly through the material as if it were not there.

Astronomers have found an enormous hole in the Universe, nearly a billion light-years across, empty of both normal matter such as stars, galaxies, and gas, and the mysterious, unseen "dark matter." While earlier studies have shown holes, or voids, in the large-scale structure of the Universe, this new discovery dwarfs them all.

Seems like an innocent enough question, right? Absolute zero is about minus 460 F. You can't get colder than that. The highest-temperature question gets to the heart of current inquiries and proposed theories in cosmology and theoretical physics. Indeed, scientists who work in these fields are zealously trying to answer that question.

A powerful jet from a super massive black hole is blasting a nearby galaxy, according to new findings from NASA observatories. This never-before witnessed galactic violence may have a profound effect on planets in the jet's path and trigger a burst of star formation in its destructive wake.

A "universe in a test tube" that could be used to assess theories of everything has been created by physicists. Inside the tube an isotope of helium (called helium three) forms a "superfluid", an ordered liquid where all the atoms are in the same state according to the theory that rules the subatomic domain, called quantum theory.

Scientists have come up with the radical suggestion that the universe's end may come not with a bang but a standstill - that time could be literally running out and could, one day, stop altogether.

This article shows the idea that age of the universe is not a constant but it varies from place to place in the universe because of Einstein's theory and thus challenging the idea of dark energy!
