Entanglement, the quantum mechanical phenomenon, was coined as a term by Erwin Schrödinger in 1935 but is still not understood completely. From an applied perspective, while entangled particles cannot be defined as single particles with defined states but are instead a whole system, that means by entangling single quantum bits, a quantum computer should solve problems considerably faster than conventional computers.
But understanding entanglement when there are two particles is tough enough. When there are many, it's even trickier, but a new experiment in the research group led by Rainer Blatt at the Institute for Experimental Physics at the University of Innsbruck may provide some insight.
Generally, coffee can be good for you just like in moderation fast food can be less bad for you. Together, they are worse, according to a new University of Guelph study.
Researcher Marie-Soleil Beaudoin says a healthy person's blood sugar levels spike after eating a high-fat meal, but also that the spike doubles after having both a fatty meal and caffeinated coffee – jumping to levels similar to those of people at risk for diabetes. The study in the Journal of Nutrition examined the effects of saturated fat and caffeinated coffee on blood sugar levels using a fat cocktail which contains only lipids. This specially designed beverage allows researchers to accurately mimic what happens to the body when we ingest fat.
A gigantic theropod dinosaur has been discovered in China.
According to findings published in Cretaceous Research, the newly named dinosaur species Zhuchengtyrannus magnus probably measured about 11 meters long, stood about 4 meters tall, and weighed close to 6 tons. The identification was done from fossil skull and jaw bones
Deaths due to cancer for both men and women in the United States continued to decline between 2003 and 2007, according to the latest Annual Report to the Nation on the Status of Cancer.
Overall rates of new cancer diagnoses for men and women combined decreased an average of slightly less than 1 percent per year for the same period.
Gravity does funny things. While the Earth looks rather round in pictures from space, the distortions that would have to occur in order to have uniform gravity everywhere would make it look more like...a potato, or a squashed basketball.
ESA's GOCE satellite has gathered enough data to map Earth's gravity with unrivaled precision, and so we get the most accurate model of the 'geoid' ever produced. The geoid is the surface of an ideal global ocean in the absence of tides and currents, shaped only by gravity. It is a crucial reference for measuring ocean circulation, sea-level change and ice dynamics.
Open access, where scientists pay a fee to publish so that the public and other scientists can read the study for free, is a negligible issue to most scientists, according to a new research report in The FASEB Journal.
