Could a plant "intervention" improve the well-being of patients in a difficult rehab process?
Scientists from the Norwegian University of Life Sciences and Sweden's Uppsala University investigated this question in a recent study of 436 coronary and pulmonary patients at a Norwegian rehabilitation center. The results were published in HortScience. Ruth Kjærsti Raanaas, Grete Grindal Patil, and Terry Hartig studied the effects of an indoor plant intervention during a 2-year study conducted at the Røros Rehabilitation Center.
The experiment showed that patients' overall physical and mental health improved during the program, but the presence of new plants did not increase the degree of improvement. One encouraging finding: pulmonary patients in the "plant intervention group" reported a larger increase in well-being during their rehabilitation program more often than lung patients from the "no-plant" control group.
For the intervention, 28 new plants were placed in common areas at the rehab center, which had previously contained only a few poorly maintained plants. Aside from the introduction of the new plants and removal of some older plants, no other changes were made to the interior decoration during the study period. Coronary and pulmonary patients completed self-assessments upon arrival at the center, after 2 weeks, and at the end of a 4-week program. The research project, designed to investigate whether the addition of indoor plants in the common areas would improve self-reported physical and mental health, subjective well-being, and emotions among patients over the course of their rehabilitation program, was funded by the Norwegian Foundation for Health and Rehabilitation, the Norwegian Gardener's Union, the Bank of Røros, Tropisk Design, and Primaflor.
According to Raanaas, the team found no "significant direct effects" of the plant intervention on change in either of the self-reported health outcomes. "The results did, however indicate that the plant intervention affected the degree of change in subjective well-being, although this effect was further contingent on patient group."
The team postulated that the study outcomes may have been limited by the rehab center's well-designed interior and location in a scenic mountain area, but noted that these features did not negate the potential for indoor plants to contribute to patient well-being. "One reason why the plant intervention did not influence the health outcomes in the present study may be that the participants were mobile and were exposed to a variety of treatments and activities at the center", the researchers concluded.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
