When dying, bacteria share some characteristics with higher organisms
Do bacteria, like higher organisms, have a built-in program that tells them when to die? The process of apoptosis, or cell death, is an important part of normal animal development. In a new study published March 6 in the ...

Light now in sight: Control of a 'blind' neuroreceptor with an optical switch
When nerve cells communicate with one another, specialized receptor molecules on their surfaces play a central role in relaying signals between them. A collaborative venture involving teams of chemists based at Ludwig-Maximilians-Universitat ...

Digital versus analog control over cortical inhibition
In the cerebral cortex, the balance between excitation (pyramidal neurons) and inhibition (interneurons) is thought to be mediated by the primary mode of neuronal communication: "all-or-none" action potentials, or spikes. ...

Nonvolatile memory based on ferroelectric-graphene field-effect transistors is now a step closer to reality
A fundamental component of a field-effect transistor (FET) is the gate dielectric, which determines the number of charge carriers -- electrons or electron vacancies -- that can be injected into the active ...

Genome-wide hunt reveals links to abnormal rhythms behind sudden death, heart damage
A study among almost 50,000 people worldwide has identified DNA sequence variations linked with the heart's electrical rhythm in several surprising regions among 22 locations across the human genome. The variants were found ...
