Michael Milane and colleagues (University of California, Los Angeles) analyzed suicide rates in the US general population from 1960-2002. Suicide rates fluctuated between 12.2 and 13.7 per 100,000 until 1988, and then gradually fell, with the lowest value of 10.4 per 100,000 in 2000.
The researchers also analyzed data on prescriptions of fluoxetine, which was introduced in 1988. There was an increase in the number of fluoxetine prescriptions, from about 2.5 million in 1988 to over 33 million in 2002.
Mathematical tests showed that the steady decline in suicides was statistically associated with the increased number of fluoxetine prescriptions (the more prescriptions, the fewer suicides). The authors hypothesize that fluoxetine might have saved 33,600 lives since its introduction.
Milane and colleagues acknowledge that the association they found between the fall in suicides and the introduction of fluoxetine cannot prove that the medication caused the fall. There may have been other reasons why the suicide rate declined.
Nevertheless, they argue that their findings are helpful in shedding light on the ongoing debate about whether fluoxetine (and other “SSRI antidepressants”) might trigger an increase in suicide. “Although the current issue concerning antidepressants and suicidality requires further examination,” they say, “we believe that many more lives have been saved than lost since the advent of these drugs.”
In a commentary on the new study, Bernhard Baune and Philippa Hay (James Cook University, Australia), who were not involved in the study, say that the type of study performed by Milane and colleagues cannot prove for certain “whether antidepressants do harm or good at a population level.” Nevertheless, they say that the study “does not support an association between increased suicide and increased fluoxetine prescription rates.”

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
