Scientists discover protein instrumental to brain development and repair

Scientists at Children's National Medical Center have demonstrated conclusively that a specific protein and its signaling activity are instrumental in myelination and remyelination, processes essential to the creation and repair of the brain's white matter.

Amoebae control cheating by keeping it in the family

No one likes a cheater, even a single-celled one. New research from Rice University shows how cooperative single-celled amoebae rely on family ties to keep cheaters from undermining the health of their colonies.

Breakthrough new asthma gene found

In a large-scale study conducted with 2,643 children, international researchers with the participation of the Department of Experimental Pneumology of Ruhr-University Bochum (RUB), Germany (Prof. Dr. Albrecht Bufe), have discovered a gene variant that contributes significantly to the risk of childhood asthma.

People with narcolepsy have a high frequency of REM sleep without muscle atonia

Normal rapid eye movement (REM) sleep is characterized by tonic features, including cortical electroencephalogram (EEG) desynchronization and muscle atonia, as well as phasic events, including bursts of REM, phasic activities of both chin and limb electromyography (EMG), and cardiorespiratory variability.
