Neutrinos which appeared to have undermined a basic law of the universe by exceeding the speed of light might have done so even faster than first thought – or might not have done it at all, said scientists at the Gran Sasso laboratory in Italy. Tests on the equipment used in their experiment had led…
The Heisenberg uncertainty principle is often invoked outside the realm of physics to describe how the act of observing something changes the thing being observed, or to point out that there’s a limit to how well we can ever really understand the universe. While the subtleties of the uncertainty principle are often lost on nonphysicists,…
The Fermi Paradox asks the simple question “where are they?” Our Milky Way galaxy is so big and so old — and we are estimated to be accompanied by at least 100 billion planets — that aliens should have visited us by now. Instead, when we peruse the heavens, we are faced with the Great…
Recent media stories suggest that anti-aging medicine may soon change from fantasy into a scientifically realistic prospect. If anti-aging medicine is to become a reality, then the various theories about how to halt or reverse the aging process will require testing on human subjects. Carrying out such tests will place unprecedented pressure on the rules…
Fundamental particles are the building blocks of matter, and, apparently, come in many more flavors than the basic few that make up the atoms we’re familiar with. Flavor is the name scientists give to different versions of the same type of particle. For instance, quarks (which make up the protons and neutrons inside atoms) come…
Obsessive gamers’ hours at the computer have now topped scientists’ efforts to improve a model enzyme, in what researchers say is the first crowdsourced redesign of a protein. The online game Foldit allows players to fiddle at folding proteins on their home computers in search of the best-scoring (lowest-energy) configurations. Researchers have previously reported successes…
Scientists at Denmark’s Niels Bohr Institute have figured out a cool new way to lower the temperature of hot semiconductors. In a seemingly paradoxical new study, the scientists showed that light from a laser caused the temperature of semiconductor material to drop–and not by just a few degrees. The temperature fell to -269 Celsius –…
The search for the perfect alliance between science and technology has married quantum computing to the future of IT – the cloud. Researchers have used quantum mechanics to encrypt heavy-duty number-crunching computing, thereby removing a major obstacle in the adoption of the cloud for many enterprises – how safe is my data when it’s hosted…
What existed before the big bang? What is the nature of time? Is our universe one of many? On the big questions science cannot (yet?) answer, a new crop of philosophers are trying to provide answers. Stephen Hawking may have famously declared that “Philosophy is dead.” but philosopher of physics Tim Maudlin disagrees. Maudlin, whose…
We tend to see modernity in part as a triumph of science—an age when experimental discoveries and analysis have eclipsed religion and other ancient beliefs. And it is our scientific understanding of the world and mastery of technology that will mold the future of human affairs. Not so fast, says Robert N. McCauley. McCauley, a…
