Your circadian rhythm doesn’t just govern your sleeping schedule; it can also impact cancer development, diagnosis, and treatment. In a review paper published in the journal Trends in Cell Biology, researchers discuss the role of circadian rhythms in tumor progression and spread and describe how we could better time when patients are tested for cancer and when they receive therapies to improve diagnostic accuracy and improve treatment success.
“The circadian rhythm governs most of the cellular functions implicated in cancer progression, and therefore its exploitation opens new promising directions in the fight against metastasis,” write the authors, molecular oncologists Zoi Diamantopoulou, Ana Gvozdenovic, and Nicola Aceto from the ETH Zurich in Switzerland.
Our circadian rhythms help our bodies synchronize different tasks throughout the day, including gene expression, immune function, and cell repair. We’ve long known that chronically disrupted circadian rhythms—as a result of erratic sleep patterns, jet lag, or shift work, for example—can predispose us to a number of health issues, including cancer. More recent work has shown that circadian rhythms are not only involved in tumor onset, but also govern cancer progression and metastasis, the colonization of secondary sites within the body.
It’s pretty well known that usually two sexes have to be involved for reproduction, but a team of scientists in Japan might have just blown that assumption out of the water. Led by Katsuhiko Hayashi, a professor of genome biology at Osaka University in Japan, the team have been able to create mice with parents who are both biologically male.

Doctors are assuring the public that it’s not going to take over the world and kill us all, but it is something we need to be aware of.
The researchers add that these data demonstrate that CRISPRa is generally applicable across chromatin states and cell types, and highlights the factors that impact the degree of gene activation and how easy it is to reproduce the effects. Understanding these factors is important in the design and analysis of CRISPRa screens, which are used to look for genes involved in genetic diseases, the team points out.
Further study is required to continue to add to these rules and to see whether different CRISPRa or CRISPR interference techniques behave in a similar way.
“Our research has established a system for reporting the effectiveness of CRISPR activation in stem cells, allowing us to gain a better understanding of how CRISPRa works in multiple cell states,” says Qianxin Wu, PhD, first author from Wellcome Sanger. “We also showed that CRISPR gene activation is powerful enough to induce stem cells to differentiate into other cell states. This suggests that CRISPRa screens can be used to search for genes involved in cellular processes or to generate more accurate models of cell types in the body, aiding research into genetic diseases and regenerative medicine.”
Who would have thought that video games are good for TBI? I play them sometimes. Time for that, and not just music.
Video games may help TBI patients recover their physical and cognitive abilities faster than traditional therapy, according to recent research.
Although they might seem like just a pleasant distraction, video games engage several parts of the brain at once and can even promote neuroplasticity.

Researchers from the University of Geneva (UNIGE), the Geneva University Hospitals (HUG), and the National University of Singapore (NUS) have developed a novel method for evaluating the interpretability of artificial intelligence (AI) technologies, opening the door to greater transparency and trust in AI-driven diagnostic and predictive tools. The innovative approach sheds light on the opaque workings of so-called “black box” AI algorithms, helping users understand what influences the results produced by AI and whether the results can be trusted.
This is especially important in situations that have significant impacts on the health and lives of people, such as using AI in medical applications. The research carries particular relevance in the context of the forthcoming European Union Artificial Intelligence Act which aims to regulate the development and use of AI within the EU. The findings have recently been published in the journal Nature Machine Intelligence.
Time series data—representing the evolution of information over time—is everywhere: for example in medicine, when recording heart activity with an electrocardiogram (ECG); in the study of earthquakes; tracking weather patterns; or in economics to monitor financial markets. This data can be modeled by AI technologies to build diagnostic or predictive tools.
Having both diabetes and tooth loss contributes to worse cognitive function and faster cognitive decline in older adults, according to a new study published in a special issue of the Journal of Dental Research focused on aging and oral health.
“Our findings underscore the importance of dental care and diabetes management for older adults in reducing the devastating personal and societal costs of Alzheimer’s disease and other related dementias,” said Bei Wu, vice dean for research at NYU Rory Meyers College of Nursing and co-director of the NYU Aging Incubator, as well as the study’s lead author.
Diabetes is a known risk factor for cognitive decline and dementia. Several of the hallmarks of diabetes —high blood sugar, insulin resistance, inflammation, and related heart disease—are thought to contribute to changes in the brain.
