Computer scientists form mathematical formulation of the brain's neural networks
As computer scientists this year celebrate the 100th anniversary of the birth of the mathematical genius Alan Turing, who set out the basis for digital computing in the 1930s to anticipate the electronic age, they still quest ...

Quantum copies do new tricks
One of the strange features of quantum information is that, unlike almost every other type of information, it cannot be perfectly copied. For example, it is impossible to take a single photon and make a number of photons ...

Scientists observe how superconducting nanowires lose resistance-free state
Even with today's invisibility cloaks, people can't walk through walls. But, when paired together, millions of electrons can.

Research defines dendritic cell lineage
(PhysOrg.com) -- Dendritic cells were discovered more than 30 years ago, but their pedigree has never been fully charted. They were known to be key immune system cells born in bone marrow, but their adolescence remained a ...

It's Easier to Observe the Failure of Local Realism than Previously Thought
(PhysOrg.com) -- Local realism is something we live with every day, even if we don’t realize it. The principle of local realism combines two assumptions: locality and realism. Locality says that distant objects cannot directly ...

Physicists working up from atoms to Schrodinger's cat
(PhysOrg.com) -- Schrodinger's cat, a macroscopic object that is both alive and dead at the same time, illustrates the strangeness of quantum mechanics. While such quantum properties have been widely observed for electrons ...

Findings turn events in early TB infection on their head, may lead to new therapy
Masses of immune cells that form as a hallmark of tuberculosis (TB) have long been thought to be the body's way of trying to protect itself by literally walling off the bacteria. But a new study in the January 9th issue of ...
