A 3-D light switch for the brain

A new tool for neuroscientists delivers a thousand pinpricks of light to a chunk of gray matter smaller than a sugar cube. The new fiber-optic device, created by biologists and engineers at the Massachusetts Institute of ...

The first controllable atom SQUID

(Phys.org)—Scientists have created the first controllable atomic circuit that functions analogously to a superconducting quantum interference device (SQUID) and allows operators to select a particular quantum state of the ...

Improved nanoparticles deliver drugs into brain

The brain is a notoriously difficult organ to treat, but Johns Hopkins researchers report they are one step closer to having a drug-delivery system flexible enough to overcome some key challenges posed by brain cancer and ...

Modeling the demise of migrating brain tumor cells

An Israeli physicist has developed a theoretical model to simulate the evolution of highly proliferating brain tumour core cells subjected to treatment by alternating radio frequency electric field. The research, by Alexander ...

A new shortcut for stem cell programming

Scientists at the Life and Brain Research Center at the University of Bonn, Germany, have succeeded in directly generating brain stem cells from the connective tissue cells of mice.

New type of extra-chromosomal DNA discovered

(PhysOrg.com) -- A team of scientists from the University of Virginia and University of North Carolina in the US have discovered a previously unidentified type of small circular DNA molecule occurring outside the chromosomes ...
