Machine learning algorithms play important roles in medical imaging analysis but can be affected by biases in training data. Jones and colleagues discuss how causal reasoning can be used to better understand and tackle algorithmic bias in medical imaging analysis.
The study revealed that the use of graphene oxide had no adverse effects on lung function, blood pressure, or the majority of other biological parameters under scrutiny.
The findings of the study promise to advance our grasp of graphene’s health effects, facilitating safer incorporation into industries, notably medicine.
This CU Cancer Center symposium was presented by Sandra McAllister, PhD, assistant professor of medicine at the Harvard Medical School, and associate scientist at Brigham \& Women’s Hospital.
Researchers are devising a blood test screening for 11 newly discovered biomarkers of dementia. They say the test could predict its development 15 years before symptom onset.
Scientists have welcomed a “truly wonderful” new drug for a hard-to-treat and aggressive form of cancer.
Researchers led by a team at Queen Mary University of London said their new treatment “quadrupled” three-year survival rates and increased average survival by 1.6 months.
Academics said that the new drug, which works by cutting off the tumour ’s food supply, is the first of its type for mesothelioma in 20 years.

Currently listening to this. He’s pretty decent, up there with Dr Daniel Amen in advancement/ideas. I barely started this episode but it seems AI can help in medicine and there’s more in this podcast concerning our personal health. This is some key issues for longevity.

Studies show that physical activity is actually a mental health exercise. One article that states just 15 minutes of walking, especially in the out-of-doors, can boost mood and reduce feelings of depression.
People seem to think more clearly after a brisk walk as well. It makes sense. As the heart pumps oxygen and nutrients to working muscles, the brain gets the same benefits.
Are there foods that might help our brains stay focused? In 2015, scientists reported on a diet that was found to help slow the gradual decline in cognitive function we may experience as we age. It was a hybrid of the Mediterranean diet and the DASH diet (Dietary Approaches to Stop Hypertension) cutely named the MIND diet (Mediterranean-DASH Diet Intervention for Neurodegenerative Delay).
This isn’t rocket science it’s neuroscience.
Ever since the dawn of antiquity, people have strived to improve their cognitive abilities. From the advent of the wheel to the development of artificial intelligence, technology has had a profound leverage on civilization. Cognitive enhancement or augmentation of brain functions has become a trending topic both in academic and public debates in improving physical and mental abilities. The last years have seen a plethora of suggestions for boosting cognitive functions and biochemical, physical, and behavioral strategies are being explored in the field of cognitive enhancement. Despite expansion of behavioral and biochemical approaches, various physical strategies are known to boost mental abilities in diseased and healthy individuals. Clinical applications of neuroscience technologies offer alternatives to pharmaceutical approaches and devices for diseases that have been fatal, so far. Importantly, the distinctive aspect of these technologies, which shapes their existing and anticipated participation in brain augmentations, is used to compare and contrast them. As a preview of the next two decades of progress in brain augmentation, this article presents a plausible estimation of the many neuroscience technologies, their virtues, demerits, and applications. The review also focuses on the ethical implications and challenges linked to modern neuroscientific technology. There are times when it looks as if ethics discussions are more concerned with the hypothetical than with the factual. We conclude by providing recommendations for potential future studies and development areas, taking into account future advancements in neuroscience innovation for brain enhancement, analyzing historical patterns, considering neuroethics and looking at other related forecasts.

The authors of a recent review published in Ageing Research Reviews summarize the research on epigenetic reprogramming and its potential as a rejuvenation therapy [1].
Aging leads to changes in the epigenome. Those changes can lead to alterations in gene regulation, affecting cellular homeostasis, and can play a role in age-associated phenotypes. Epigenetic modifications, the addition or removal of chemical groups to the DNA or DNA-associated proteins, have a profound impact on gene expression, tissue functions, and identity [2].
This review’s authors believe epigenetic reprogramming to be among the most currently promising interventions to stop or delay aging, potentially even reversing it at the cellular level. They believe that epigenetics are the basis of aging; therefore, being able to impact the epigenome would allow them to address multiple Hallmarks of Aging simultaneously.
Semiconductor devices are small components that manage the movement of electrons in contemporary electronic gadgets. They are essential for powering a wide range of high-tech products, including cell phones, laptops, and vehicle sensors, as well as cutting-edge medical devices. However, the presence of material impurities or variations in temperature can interfere with electron flow, causing instability.
But now, theoretical and experimental physicists from the Würzburg-Dresden Cluster of Excellence ct.qmat—Complexity and Topology in Quantum Matter have developed a semiconductor device from aluminum-gallium-arsenide (AlGaAs). This device’s electron flow, usually susceptible to interference, is safeguarded by a topological quantum phenomenon. This groundbreaking research was recently detailed in the esteemed journal Nature Physics.
“Thanks to the topological skin effect, all of the currents between the different contacts on the quantum semiconductor are unaffected by impurities or other external perturbations. This makes topological devices increasingly appealing for the semiconductor industry. They eliminate the need for the extremely high levels of material purity that currently drive up the costs of electronics manufacturing,” explains Professor Jeroen van den Brink, director of the Institute for Theoretical Solid State Physics at the Leibniz Institute for Solid State and Materials Research in Dresden (IFW) and a principal investigator of ct.qmat.
