A new study from UK researchers suggests that deficits in prospective memory (remembering to remember, or remembering to perform an intended action) are more common for recreational drug users. The new research appears in the Journal of Psychopharmacology.

42 ecstasy/polydrug users (14 males, 28 females) and 31 non-users (5 males, 26 females)  were recruited for the study – all were students. The students were quizzed about their drug habits (including tobacco, cannabis and alcohol), and given questionnaires to assess their everyday memory, cognitive failures and prospective and retrospective memory.
What makes Hollywood blockbusters? Scientists writing in Psychological Science may have the answer. Using the sophisticated tools of modern perception research to deconstruct 70 years of film, shot by shot, the Cornell researchers say that successful movies follow a particular mathematical pattern.

The team of psychologists measured the duration of every shot in every scene of 150 of the most popular films released from 1935 to 2005. The films represented five major genres—action, adventure, animation, comedy and drama. Using a complex mathematical formula, they translated these sequences of shot lengths into "waves" for each film.
A new study published this week in PLoS Biology suggests that seasonal changes in absolute humidity are the apparent underlying cause of wintertime influenza outbreaks. The study also found that the onset of outbreaks might be encouraged by anomalously dry weather conditions, at least in temperate regions.
New research from Tel Aviv University and MIT suggests that magnesium, a key nutrient for the functioning of memory, may be even more critical than previously thought. The multi-center experiment focused on a new magnesium supplement, magnesium-L-theronate (MgT), and found that the synthetic compound enhances memory or prevents its impairment in young and aging animals. The research was carried out over a five-year period and may have significant implications for the use of over-the-counter magnesium supplements.
Patients diagnosed with clinical depression may respond better to medical treatment as a result of belief in a personal God, say researchers at Rush University Medical Center writing in the Journal of Clinical Psychology.

136 adults diagnosed with major depression or bipolar depression at inpatient and outpatient psychiatric care facilities in Chicago participated in the study. The patients were surveyed shortly after admission for treatment and eight weeks later, using the Beck Depression Inventory, the Beck Hopelessness Scale, and the Religious Well-Being Scale – all standard instruments in the social sciences for assessing intensity, severity and depth of disease and feelings of hopelessness and spiritual satisfaction.
Researchers have found a new oncogenic signaling pathway by which arsenic exposure may lead to adverse health effects, including bladder cancer. The results appear in Cancer Research.

While the correlation between arsenic exposure and cancer tumors such as those derived from bladder, lung and skin is well established, the molecular mechanisms driving this connection has remained unclear.
