Now we know why old scizophrenia medicine works on antibiotics-resistant bacteria
|
|
|

So far it has been a mystery how this old schizophrenia medicine works, but now researchers have figured it out. This can lead to a new medicine against the increasingly threatening antibiotic-resistant bacteria.

Individuals who drink heavily and smoke may show 'early aging' of the brain
|
|
|
Alcohol treatment interventions work best when patients understand and are actively involved in the process. A first-of-its-kind study looks at the interactive effects of smoking status and age on neurocognition in one-month-abstinent alcohol dependent (AD) individuals in treatment. Results show that AD individuals who currently smoke have more problems with memory, ability to think quickly and efficiently, and problem-solving skills than those who do not smoke, effects which seem to become greater with increasing age.
