Emotional body odors may have the potential to enhance the anxiety-reducing effects of mindfulness. This is shown by a pilot study published in the Journal of Affective Disorders, co-authored by researchers from Karolinska Institutet.
Body odors can serve as a means of social communication. Body odors, such as sweat, contain a cocktail of chemical processes (so-called chemosignals), which in turn are influenced by a person’s emotional state. Studies indicate that individuals exposed to chemosignals from a person in a particular emotional state, such as fear or happiness, exhibit a certain replication of this state. This replication occurs unconsciously and has most often been observed through different physiological tests.
As most studies in this area have involved healthy subjects, the overall goal of this project was to study the potential benefit of chemosignals for individuals with psychiatric symptoms. The purpose of this study was therefore to investigate whether emotional body odors can enhance the benefits of a mindfulness-based intervention for individuals with social anxiety or depression.
Artificial intelligence has the potential to improve the analysis of medical image data. For example, algorithms based on deep learning can determine the location and size of tumors. This is the result of AutoPET, an international competition in medical image analysis, where researchers of Karlsruhe Institute of Technology (KIT) were ranked fifth.
The seven best autoPET teams report in the journal Nature Machine Intelligence on how algorithms can detect tumor lesions in positron emission tomography (PET) and computed tomography (CT).
Imaging techniques play a key role in the diagnosis of cancer. Precisely determining the location, size, and type of tumor is essential for choosing the right therapy. The most important imaging techniques include positron emission tomography (PET) and computer tomography (CT).
Colorectal cancer (CRC) remains one of the most clinically challenging malignancies facing our public health system. CRC accounts for the second and third most common cancer in males and females, respectively. In addition, CRC represents one of the most deadly cancers, expected to result in over 50,000 mortalities in 2024.
Hereditary colorectal cancer (HCRC) occurs when a parent passes a cancer gene to a child. Unfortunately, we have not identified a single gene that causes the disease. Hereditary CRC syndromes, such as hereditary non-polyposis colorectal cancer (HNPCC; also known as Lynch syndrome) and familial adenomatous polyposis (FAP), describe a group of genetic diseases that confer a high risk of developing CRC. As our knowledge has expanded, we have learned about a growing number of genetic variants in the genes that predispose carriers to CRC. However, the precise role of some variants in the development of CRC cancer remains unclear. Uncovering more information about these variants, called variants of uncertain significance.

Uncovering more information about these variants, called variants of uncertain significance (VUS), can aid in optimizing screening and surveillance programs.

Space-time may not be continuous but instead made up of many discrete bits – and we may be able to see their effects near the edges of unusually bright black holes.
Nanotechnology is poised to transform neurological disorder treatments by overcoming the blood-brain barrier, enabling effective medication delivery for conditions like dementia and Alzheimer’s. This innovative approach also shows promise in dermatology and cancer treatment, enhancing drug absorption and targeting, while minimizing side effects. Experts at AIIMS highlighted ongoing research and potential breakthroughs expected in the next few years.
Skeletal editing has emerged as an appealing strategy for scaffold-hopping-based drug discovery, but the enantioselective single-atom skeletal editing of N-heteroarenes is challenging. Now, using trifluoromethyl N-triftosylhydrazones as carbene precursors, the enantiodivergent dearomative skeletal editing of indoles and pyrroles has been achieved through asymmetric carbon-atom insertion.
