(Press-News.org) Music is central to human emotion and culture. Does our ability to enjoy music have a biological basis? A genetic twin study, published in Nature Communications, shows that music enjoyment is partly heritable. An international team led by scientists from the Max Planck Institute for Psycholinguistics in Nijmegen, the Netherlands, uncovered genetic factors that influence the degree of music enjoyment, which were partly distinct from genes influencing general enjoyment of rewarding experiences or musical ability.
Music plays an important role in human emotion, social bonding, and cultural expression. As Darwin already noted, music "must be ranked amongst the most mysterious with which he is endowed". But why do people enjoy music?
“The answer to this big question has the potential to open a window into more general aspects of the human mind, such as how experiences become pleasurable”, says first author and PhD candidate Giacomo Bignardi. “We wanted to understand whether genetic differences between individuals can result in differences in the pleasure that people derive from music and what these differences can tell us about human musicality in general”.
To determine whether genetic factors contribute to music enjoyment or ‘music reward sensitivity’, the researchers used the twin design, which compares similarities between identical twins and fraternal twins. Put simply, if identical twins are more similar than fraternal twins, genetics should play a role.
In collaboration with the MPI for Empirical Aesthetics in Germany and the Karolinska Institute in Sweden, the team was able to use data from more than 9,000 twins, including self-reported music reward and general reward sensitivity, as well as their ability to perceive musical features such as pitch, melody and rhythm.
The results show that the ability to experience pleasure from music is partly heritable: using the twin design, the researchers were able to estimate that 54% of the variability in the Swedish sample is associated with DNA differences between individuals.
The team also found genetic influences on music reward sensitivity to be partly independent of general reward sensitivity and music perceptual abilities, and discovered that distinct genetic pathways influenced different facets of music enjoyment, such as emotion regulation, dancing along with a beat or playing music with others.
“These findings suggest a complex picture in which partly distinct DNA differences contribute to different aspects of music enjoyment”, concludes Bignardi. “Future research looking at which part of the genome contributes the most to the human ability to enjoy music has the potential to shed light on the human faculty that baffled Darwin the most, and which still baffles us today.”

Global patterns in seed plant distribution over millions of years
2025-03-28
Why do some plants thrive in specific regions but not in others? A study led by researchers at the University of Göttingen explores the factors shaping plant distributions and how these patterns have changed over millions of years. Analyzing nearly 270,000 seed plant species worldwide, the research highlights the roles of environmental conditions and dispersal barriers in influencing global plant diversity. The results were published in Nature Ecology & Evolution.
Using advanced methods that integrate plant distributions with phylogenetic information – meaning data about the evolutionary relationships among plant species – researchers ...
Fatty acids promote immune suppression and therapy resistance in triple negative breast cancer
2025-03-28
HOUSTON – (March 28, 2025) – A new study published in the journal Immunity reveals a mechanism that allows triple negative breast cancer (TNBC) to develop resistance to therapy. Researchers at Baylor College of Medicine showed that lipid accumulation in tumor cells and nearby immune cells promotes immune suppression, but disrupting lipid formulation reverses treatment resistance and the immunosuppressive microenvironment.
Standard-of-care treatment for TNBC includes chemotherapy and immunotherapy. However, some initially responsive tumors still develop recurrences. Researchers studied mouse models and found that TNBC cells that survived treatment accumulated ...
Intermittent fasting increases sex drive in male mice: an approach for low libido in humans?
2025-03-28
Long-term fasting in 24-hour cycles increases the sex drive of male mice by lowering the concentration of the neurotransmitter serotonin in the brain. This effect is linked to a diet-induced deficiency of the precursor substance tryptophan – an amino acid that must be obtained through food. Researchers from DZNE report on this in the journal Cell Metabolism, together with a Chinese team from Qingdao University and the University of Health and Rehabilitation Sciences. They suggest that similar mechanisms may exist in humans and view fasting as a potential approach for treating unwanted loss of sexual desire.

Scientists create protein ‘seeds’ that trigger key pathological features of ALS and frontotemporal dementia
2025-03-28
28 March 2024, Leuven, Belgium — Accumulation of a protein called TDP-43 is a key feature of ALS and frontotemporal dementia. In a newly published study, researchers report ‘seeding’ this accumulation through fragments of the culprit protein created in the lab. The findings provide further evidence for a prion-like paradigm wherein protein aggregation occurs in a templated fashion. This breakthrough provides the research field with a powerful way to model and study the mechanisms driving neurodegeneration.

New approach makes one type of clean fuel production 66% more efficient
2025-03-28
COLUMBUS, Ohio – Researchers have uncovered a more efficient way to turn carbon dioxide into methanol, a type of alcohol that can serve as a cleaner alternative fuel.
In the lab, synthesizing methanol can be extremely difficult, due to the extremely complex reaction pathway needed to select for it. Previous attempts by the same team to manufacture this valuable liquid fuel from carbon dioxide have used a combination of cobalt phthalocyanine (CoPc) molecules and electricity, but this method is inefficient as only about 30% of the carbon dioxide is converted to methanol.

AI meets oncology: New model personalizes bladder cancer treatment
2025-03-28
Leveraging the power of AI and machine learning technologies, researchers at Weill Cornell Medicine developed a more effective model for predicting how patients with muscle-invasive bladder cancer will respond to chemotherapy. The model harnesses whole-slide tumor imaging data and gene expression analyses in a way that outperforms previous models using a single data type.
The study, published March 22 in npj Digital Medicine, identifies key genes and tumor characteristics that may determine treatment success. The ability to accurately anticipate ...
New approach could treat anthrax beyond the “point of no return”
2025-03-28
Anthrax, an infectious disease caused by the bacterium Bacillus anthracis, is often treatable in its early stages. But once the disease has progressed beyond the “point of no return” after just a few days, patients are almost certainly doomed.
In a new Nature Microbiology study, University of Pittsburgh researchers show that a cocktail of growth factors reversed would-be lethal cell damage in mice with anthrax, suggesting that this approach could be adapted for use in patients beyond the brink.
“While only a few people die from anthrax in the United States each year, there is always the concern ...
Those constantly distracted by their phone will just find other ways to procrastinate if it isn’t nearby
2025-03-28
If you just put away your phone to read this, chances are you’re not alone. Our phones are an endless source of distraction, and we interact with them every four to six minutes. This is often driven by habit as well as notifications, leading to a disrupted flow of activity while we’re trying to be productive.
A new study published in Frontiers in Computer Science investigated if placing smartphones just out of our reach while we’re at work influenced device use for activities not related ...
Ottoman Empire’s religious ‘tolerance’ another form of control
2025-03-28
Population surveillance. The carrying of identification while traveling. Add to that the public presence of diverse religions and it sounds like 2025, but this was life in the Ottoman Empire 200 years ago. Yet this seeming tolerance of non-Muslim faiths was in fact tied to the first two aspects, according to research by Osaka Metropolitan University Associate Professor Masayuki Ueno.
The Ottoman Empire lasted from around 1300 until 1922, and at various points in its history ruled present-day Turkey, Egypt, Greece, Hungary, and beyond. In the wake of the 1821 Greek revolt, the Ottoman Empire instituted ...
