This study aimed to investigate whether there are structural differences in the brains of professional artists who received formal training in the visual arts and non-artists who did not have any formal training or professional experience in the visual arts, and whether these differences can be used to accurately classify individuals as being an artist or not. Previous research using functional MRI has suggested that general creativity involves a balance between the default mode network and the executive control network. However, it is not known whether there are structural differences between the brains of artists and non-artists. In this study, a machine learning method called Multi-Kernel Learning (MKL) was applied to gray matter images of 12 artists and 12 non-artists matched for age and gender. The results showed that the predictive model was able to correctly classify artists from non-artists with an accuracy of 79.17% (AUC 88%), and had the ability to predict new cases with an accuracy of 81.82%. The brain regions most important for this classification were the Heschl area, amygdala, cingulate, thalamus, and parts of the parietal and occipital lobes as well as the temporal pole. These regions may be related to the enhanced emotional and visuospatial abilities that professional artists possess compared to non-artists. Additionally, the reliability of this circuit was assessed using two different classifiers, which confirmed the findings. There was also a trend towards significance between the circuit and a measure of vividness of imagery, further supporting the idea that these brain regions may be related to the imagery abilities involved in the artistic process.

This paper considers the relationship between performance art, recent museological models focused on the centrality of the public, and the visitors’ ontological status as embodied, cognitive and sentient beings. It discusses the shift from traditional curatorship towards a participatory model, curated for the visitor rather than about objects. It frames the thinking about the public as embodied/sentient entity, whose perceptual mechanisms need to be fully understood in order to design fully participatory, engaging and stimulating exhibitions. It surveys and addresses performance art as exemplary to understand the relationship between the space of the museum and the bodies of the artists and their public, and how these elements can generate new research questions. Through its analysis, it proposes curating the public’s experience by adopting an interdisciplinary framework centered around the notion of embodiment, shared space and multisensory interaction.

Community-acquired pneumonia (CAP) represents a common cause of hospitalization in Internal Medicine wards and a frequent cause of antibiotic prescription. An approach based on procalcitonin (PCT) algorithm, has shown to reduce the antibiotic exposure without affecting outcome, in patients admitted to hospital for pneumonia We conducted a study to evaluate the role of a PCT algorithm in a real-life perspective, to reduce the length of antibiotic treatment (AT) in patients hospitalized with CAP. We performed a prospective case-control study, enrolling patients with CAP admitted to an Internal Medicine ward of Careggi Hospital, between December 2013 and February 2014. We used a validated algorithm of AT guided by PCT in CAP. Discontinuation of AT was strongly indicated when PCT level was normal or reduced by 80% in patients with PCT values higher than 10 pg/mL on admission. PCT was drawn on admission, 24 h, 4th day and 6th day from admission. The outcomes evaluated were the length of AT, the length of in hospital stay, mortality and serious adverse clinical events. Forty-six patients were consecutively enrolled. On 20 patients, AT was discontinued according to protocol and on 26 patients the AT was continued on clinical judgement. At the baseline, both groups were similar regarding clinical, laboratory, microbiology characteristics, and CURB-65 score. PCT guidance reduced total antibiotic exposure (5.1±1.5 vs 9.1±5.8 days, P=0.005) without any increase of mortality or serious clinical event. In our study, a PCT algorithm was a useful and safe tool to guide the AT in patients with CAP, reducing the antibiotic exposure.

Across cultures and throughout recorded history, humans have produced visual art. This raises the question of why people report such an emotional response to artworks and find some works more beautiful or compelling than others. In the current study we investigated the interplay between art expertise, and emotional and preference judgments. Sixty participants (40 novices, 20 art experts) rated a set of 150 abstract artworks and portraits during two occasions: in a laboratory setting and in a museum. Before commencing their second session, half of the art novices received a brief training on stylistic and art historical aspects of abstract art and portraiture. Results showed that art experts rated the artworks higher than novices on aesthetic facets (beauty and wanting), but no group differences were observed on affective evaluations (valence and arousal). The training session made a small effect on ratings of preference compared to the non-trained group of novices. Overall, these findings are consistent with the idea that affective components of art appreciation are less driven by expertise and largely consistent across observers, while more cognitive aspects of aesthetic viewing depend on viewer characteristics such as art expertise.

We present the first results of the JWST program PROJECT-J (PROtostellar JEts Cradle Tested with JWST), designed to study the Class I source HH46 IRS and its outflow through NIRSpec and MIRI spectroscopy (1.66–28 μ m). The data provide line images (∼6.″6 in length with NIRSpec, and up to ∼20″ with MIRI) revealing unprecedented details within the jet, the molecular outflow, and the cavity. We detect, for the first time, the redshifted jet within ∼90 au from the source. Dozens of shock-excited forbidden lines are observed, including highly ionized species such as [Ne iii ] 15.5 μ m, suggesting that the gas is excited by high velocity (>80 km s ^−1 ) shocks in a relatively high-density medium. Images of H _2 lines at different excitations outline a complex molecular flow, where a bright cavity, molecular shells, and a jet-driven bow shock interact with and are shaped by the ambient conditions. Additional NIRCam 2 μ m images resolve the HH46 IRS ∼110 au binary system and suggest that the large asymmetries observed between the jet and the H _2 wide-angle emission could be due to two separate outflows being driven by the two sources. The spectra of the unresolved binary show deep ice bands and plenty of gaseous lines in absorption, likely originating in a cold envelope or disk. In conclusion, JWST has unraveled for the first time the origin of the HH46 IRS complex outflow demonstrating its capability to investigate embedded regions around young stars, which remain elusive even at near-IR wavelengths.

This study aimed at investigating the potential of a novel functional herbal tea to act as the carrier for the probiotic Bacillus coagulans GanedenBC30. Spores markedly survived to infusion treatments and the simulation of the gastrointestinal transit only slightly affected the survival, which was 94.8 ± 2.8%. An in-depth investigation using the Simulator of the Human Intestinal Microbial Ecosystem (SHIME) which incorporated mucin-covered microcosms was performed. Q-PCR with targeted primers demonstrated that the probiotic quickly colonized mucosal compartments and still persisted after 4 days of wash out. As estimated by plate count combined with 16S rRNA sequencing, B. coagulans GanedenBC30 showed almost the same behavior in luminal compartments both during herbal tea intake and wash out. By summing the luminal and mucosal values and referring to whole volume of colon bioreactors, the content of viable cells of B. coagulans GanedenBC30 was largely above the probiotic threshold.
