Lower back pain is one of the most common chronic conditions of aging. In this Canadian study, senolytics were used to remove senescent cells and reduce lowe…
Somewhere in the body of a patient, a small clump of cells, growing undetected, has begun to form a tumor. It has yet to cause pain or visible symptoms of illness. Several months from now, or perhaps years, those first signs will prompt a doctor’s inquiry, a referral to a specialist, and an eventual diagnosis. Treatment will depend on how long the cancer has gone unnoticed and how far it has spread.
There were early signs, though not ones the patient or doctor could have noticed. Small fragments of RNA, cast off from dying cells or spit out of the tumor’s twisted transcriptions, floating about in the bloodstream—early signals of a tissue in distress.
A new method developed by Stanford researchers aims to bring the moment of detection much closer to the beginning. They have developed a blood-based method called RARE-seq that detects tumor-derived cell-free RNA with around 50 times the sensitivity of standard sequencing techniques.
When AI agents have the ability to create and promote their own cryptos, will humans still control monetary systems? It’s a question we should be thinking about, says Zoltan Istvan, a leading transhumanist thinker.

We are urgently working to find new treatments and cures for ALS and are currently funding over 168 research projects in 12 countries. We work with many pharmaceutical companies that have attempted to bring new treatments to market.
A new study shows that gold nanoparticles injected into the retina can restore vision in mice with retinal degeneration, offering a less invasive alternative to current retinal prostheses.
Researchers have developed engineered human microglia that detect disease-related brain changes and release therapeutic proteins precisely where needed.
A new stretchable, rechargeable sticker developed by researchers can detect authentic emotional states by measuring physiological signals like heart rate, skin temperature, and humidity, even when facial expressions are misleading.
Breast cancer is becoming increasingly treatable, but in some cases the disease can resurface even decades after a patient has been declared cancer free. This is because of cells that detach from the original tumor and hide in a dormant state in the breast or other organs.
Little is known about the mechanisms responsible for dormancy in cancer cells, and even less is known about what causes these cells to suddenly wake up. A new study from the laboratory of Israel Prize laureate Prof. Yosef Yarden at the Weizmann Institute of Science, published in Science Signaling, reveals the mechanism that puts breast cancer cells to sleep, as well as the reason that they emerge from dormancy more aggressive than they were before they became dormant.
From the earliest stage of embryonic development, through sexual maturation to the production of breast milk during pregnancy and after childbirth, breast tissue changes throughout a woman’s life. These changes are made possible by the metamorphosis that breast tissue cells undergo, from the early developmental stage, known as mesenchymal, when the cells are round, highly mobile and dividing rapidly, to the more mature, epithelial stage, when they are somewhat cubical, less active and dividing slowly.
