Sexual excitement, hunger, thirst—psychological scientists have found that activation of just one of these bodily desires can actually make people want other, seemingly unrelated, rewards more.
Take, for example, a man who finds himself searching for a bag of potato chips after looking at sexy photos of women. If this man were able to suppress his sexual desire in this situation, would his hunger also subside? This is the sort of question Mirjam Tuk, of the University of Twente in the Netherlands, sought to answer in the laboratory.
Tuk came up with the idea for the study while attending a long lecture. In an effort to stay alert, she drank several cups of coffee. By the end of the talk, she says, “All the coffee had reached my bladder. And that raised the question: What happens when people experience higher levels of bladder control?” With her colleagues, Debra Trampe of the University of Groningen and Luk Warlop of the Katholieke Universiteit Leuven, Tuk designed experiments to test whether self-control over one bodily desire can generalize to other domains as well.
In one experiment, participants either drank five cups of water (about 750 milliliters), or took small sips of water from five separate cups. Then, after about 40 minutes—the amount of time it takes for water to reach the bladder—the researchers assessed participants’ self-control. Participants were asked to make eight choices; each was between receiving a small, but immediate, reward and a larger, but delayed, reward. For example, they could choose to receive either $16 tomorrow or $30 in 35 days.
The researchers found that the people with full bladders were better at holding out for the larger reward later. Other experiments reinforced this link; for example, in one, just thinking about words related to urination triggered the same effect.
“You seem to make better decisions when you have a full bladder,” Tuk says. So maybe you should drink a bottle of water before making a decision about your stock portfolio, for example. Or perhaps stores that count on impulse buys should keep a bathroom available to customers, since they might be more willing to go for the television with a bigger screen when they have an empty bladder.
The results were a little surprising from a theoretical point of view; a lot of research in psychology has supported the concept of “ego depletion”—that having to restrain yourself wears out your brain and makes it harder to exert self-control over something else. But Tuk says this seems to work in a different way, maybe because bladder control is largely an automatic, unconscious process.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

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,...
