Two new open-source tools are set to make fluorescence lifetime imaging microscopy—or FLIM—faster, simpler and more accessible. Developed by Ph.D. student Sofia Kapsiani in Professor Gabi Kaminski Schierle's Molecular Neuroscience Group, the tools tackle long-standing technical and practical barriers in biomedical imaging.
A new study led by UCLA investigators shows that Verbal Reaction Time (VRT), the amount of time it takes a person to respond verbally, can be a marker of sleepiness in older adults. The study, which measured participants' voice data through standardized cognitive assessments, shows how VRT can passively detect excessive sleepiness, especially among older individuals using sedative medications.
Although there is a lot of discussion around negative aspects of aging and sexual problems, a new nationally representative study of 1,500 U.S. women aged 40–65 reveals that despite reporting masturbating less often, most postmenopausal women continue to experience orgasm at the same frequency and quality as their younger peers.
What can lemurs tell us about inflammation and aging, aka "inflammaging" in humans? That's the question Elaine Guevara, a biological anthropologist who studies the evolution of life history and aging in primates, set out to understand.
Every day, our brain takes countless fleeting experiences—from walks on the beach to presentations at work—and transforms them into long-term memories. How exactly this works remains a mystery, but neuroscientists believe that it involves a phenomenon called neural replay, in which neurons rapidly recreate the same activation sequences that occurred during the original experience. Surprisingly, neural replays can happen both before and after an experience, suggesting they help in both memory storage and also future planning.
Access to nature promotes physical and mental health, and it is vital for children's social and emotional development. Outdoor activities also influence family dynamics, helping to reduce stress and encourage connections.
People exposed to higher levels of air pollution may be more likely to develop meningioma, a typically noncancerous brain tumor, according to a large study published in Neurology. This common type of brain tumor forms in the lining of the brain and spinal cord. The findings do not prove that air pollution causes meningioma; they only show a link between the two.
In a newly published article in Nature Genetics, researchers from the University of Chicago have identified tumor aneuploidy—an imbalance in the number of chromosomes—as a powerful biomarker associated with resistance to immunotherapy across cancer types. The study emphasizes how combining immunotherapy with radiation may help overcome the issue of therapy resistance, offering a new framework for predicting treatment response and personalizing cancer therapy.
New research shows that contrary to the fears of many parents, video games might be able to help children with obesity exercise more.
Pain isn't just a physical sensation—it also carries emotional weight. That distress, anguish, and anxiety can turn a fleeting injury into long-term suffering.
Cancer does not develop overnight. It can take decades for cancer‐promoting changes in the genome to eventually lead to the formation of a malignant tumor.
Scientists at The Wistar Institute have discovered how a key protein from the Epstein-Barr virus (EBV), EBNA-LP, fundamentally rewires the three-dimensional structure of DNA in infected B cells to promote cancer development.
An international team of researchers led by Konstanz biologists has identified a molecular mechanism that regulates the activity of N-myristoyltransferases. This enzyme plays a role in biological signaling pathways, where dysregulation can lead to serious illness.
After nearly 15 years' research, scientists at the UdeM-affiliated CHU Sainte-Justine have developed a compound that has shown remarkable potential in preventing prematurity in mice.
The proportion of older adults with prolonged emergency department length of stay (LOS) and boarding times increased from 2017 to 2024, according to a research letter published online June 30 in JAMA Internal Medicine.
Cashew is an increasingly relevant allergen leading to anaphylaxis in children, according to a study published online June 13 in Allergy.
Health psychologists from the University of Staffordshire have adopted a novel approach to support women going through the menopause.
Brazilian researchers have discovered chemical compounds in marine sponges that have the potential to eliminate the malaria parasite, including strains that are resistant to conventional antimalarial drugs. The research results were published in the journal ACS Infectious Diseases.
Researchers from DZNE, Ludwig-Maximilians-Universität München (LMU), and Technical University of Munich (TUM) have found that the enzyme "gamma-secretase"—implicated in Alzheimer's disease and cancer—selects its reaction partners according to a complex scheme of molecular features.
