Researchers at Columbia University College of Dental Medicine have developed an exosome-based platform, “safeEXO-Cas,” that significantly enhances the delivery of CRISPR/Cas9 genome editing components to specific cells and tissues.
New details on how certain gluten-derived molecules trigger leaky gut syndrome in affected individuals. Celiac disease is a chronic autoimmune condition that occurs in around one per cent of the world’s population. It is triggered by the consumption of gluten proteins from wheat, barley, rye and some oats. A gluten-free diet protects celiac patients from severe intestinal damage. Together with colleagues, chemist Dr Veronica Dodero from Bielefeld University was able to determine new details on how certain gluten-derived molecules trigger leaky gut syndrome in celiac disease.
China’s first AI hospital, developed by Tsinghua University, features robot doctors capable of treating 3,000 patients daily, vastly outpacing human capacity.
These AI doctors, trained in a simulated environment, can diagnose and treat 10,000 patients in days, a task humans would need two years to…
China debuts an AI hospital town featuring AI doctors caring for virtual patients to advance medical consultation and evolve doctor agents.
Many people have heard of the BRCA1 and BRCA2 genes because of their association with breast cancer. But scientists have now suggested that many of the genetic variants we are born with, in a variety of different genes, can make a powerful prediction about what type of breast cancer an individual could develop, and what the outcome could be. This study has indicated that random genetic variants that are acquired over a lifetimes are far less important to breast cancer risk compared to those a person is born with; the findings have been published in Science.
“Apart from a few highly penetrant genes that confer significant cancer risk, the role of heredity factors remains poorly understood, and most malignancies are assumed to result from random errors during cell division or bad luck,” said senior study author Christina Curtis, PhD, a Professor at Stanford University. While that would make it seem like random events cause the growth of tumors, this is not what’s been observed. Instead, tumor development is influence by immunity and genetics, said Curtis. “This new result unearths a new class of biomarkers to forecast tumor progression and an entirely new way of understanding breast cancer origins.”

Physicists have linked the Doppler effect to heat transport, suggesting wave-like properties in biological tissues, with implications for medical and cosmetic technologies.
When a train approaches or an ambulance with its siren blaring nears us, we hear the sound with an increased frequency, which gradually decreases. As it passes, the frequency changes abruptly to a lower one, then decreases further. This commonly encountered phenomenon, known as the Doppler effect, can offer valuable insights into a seemingly unrelated field: heat transport.
During her chemistry Nobel Prize lecture in 2018, Frances Arnold said, “Today we can for all practical purposes read, write and edit any sequence of DNA, but we cannot compose it.” That isn’t true anymore.
