An international team of bioethicists and scientists contends it may be justified to go beyond the standing 14-day limit that restricts how long researchers can study human embryos in a dish. Going beyond this policy limit could lead to potential health and fertility benefits, and the authors provide a process for doing so.

We don't intuitively understand how to think enjoyable thoughts. But when researchers provided participants with a list of examples that were pleasant and meaningful, they enjoyed thinking 50% more than when they were instructed to think about whatever they wanted.

Urban Tanzanians have a more activated immune system compared to their rural counterparts. The difference in diet appears to explain this difference: in the cities, people eat a more western style diet, while in rural areas a traditional diet is more common. A team of researchers believe that this increased activity of the immune system contributes to the rapid increase in non-communicable diseases in urban areas in Africa.

With the help of about 200 human puzzle-takers, a computer model and functional MRI images, researchers have learned more about the processes of reasoning and decision making, pinpointing the brain pathway that springs into action when problem-solving goes south.

In recent years, researchers have begun using functional magnetic resonance imaging (fMRI) not just to better understand the neural bases of psychiatric illness, but also for experimental treatment of depression, ADHD, anxiety, PTSD, substance use disorder, and schizophrenia with real-time fMRI neurofeedback. But how well does it work?

Researchers at Baylor College of Medicine show that analysis of the proteomics, or all the protein data, from aggressive human cancers is a useful approach to identify potential novel therapeutic targets.

A new study has found people who adopt unique rituals to make everyday tasks more meaningful might feel less lonely.

Researchers reconstructed the evolutionary history of cancer cells in two patients, tracing the timeline of the mutation that causes the disease to a cell of origin. In a 63-year-old patient, it occurred at around age 19; in a 34-year-old patient, at around age 9.

A mutation that replaces a single amino acid in a potent tumor-suppressing protein makes it prone to nucleating amyloid fibrils implicated in many cancers as well as neurological diseases.

Researchers examined the role and economic impacts of recommender systems, and how they affect consumers' decisions.

Researchers have developed a method based on artificial intelligence that rapidly identifies currently available medications that may treat Alzheimer's disease. The method also reveals potential new treatment targets for the disease.

New research has found that new variants of the virus that causes COVID-19 can evade antibodies that work against the original form of the virus that sparked the pandemic, potentially undermining the effectiveness of vaccines and antibody-based drugs now being used to prevent or treat COVID-19.

Glycine can stimulate or inhibit neurons in the brain, thereby controlling complex functions. Unraveling the three-dimensional structure of the glycine transporter, researchers have now come a big step closer to understanding the regulation of glycine in the brain. These results open up opportunities to find effective drugs that inhibit GlyT1 function, with major implications for the treatment of schizophrenia and other mental disorders.

Researchers used CRISPR, a genome-editing tool, to figure out the hidden roles of a developmental gene called WOX9. It usually induces flower branching in tomatoes and influences embryo growth in a plant related to broccoli. By tweaking the DNA in the gene's nearby promoter region, the researchers found WOX9 could induce flower branching in other species. These types of genetic manipulations provide new opportunities to improve crop traits while eliminating unwanted side effects.
