Just as placebos have been shown to bring relief from pain, researchers have now found that they can affect emotion, alleviating the impact of unpleasant experiences. In an article in the June 16, 2005, issue of Neuron, researchers led by Predrag Petrovic of the Karolinska Institutet show that, in relieving anxiety, placebo treatment affects the same basic modulatory circuitry in the brain as it does for relieving pain.
In their experiments, the researchers tested the effect of placebo treatment on volunteer subjects’ ratings of unpleasant pictures, such as images of mutilated bodies. Other researchers had shown that people’s expectation of pain relief plays a major role in the effectiveness of placebos. So, in their experiments, the researchers first induced such an expectation in the subjects by administering an antianxiety drug to reduce the subjects’ unpleasant perception of the pictures. They then administered an antidote to the drug, telling the subjects that it would restore the unpleasant perception.
In tests the following day, the subjects were told they would receive the same drugs. But instead, they received a saline solution as a placebo when they saw the pictures. The subjects’ brains were also scanned during these experiments using functional magnetic resonance imaging (fMRI). This scanning technique uses harmless magnetic fields and radio waves to measure blood flow in brain regions, which reflects brain activity.

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.
The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...
An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
