As more time passes since the Big Bang, more of the Universe comes into view. But how much?
A study published today in the journal Nature Medicine led by researchers at Huntsman Cancer Institute (HCI) at the University of Utah (U of U) describes a new therapeutic approach with potential for patients with pancreatic cancer. These researchers discovered a combination drug therapy that may effectively combat the disease. HCI researchers first observed anti-cancer impacts in a laboratory setting and, subsequently, in its first use in a human patient.
The study has already progressed to a clinical trial that is now open at HCI and will soon be open at other sites in the United States. Details about the clinical trial, called THREAD, are available under National Clinical Trial Number 03825289. The combination therapy uses two drugs already approved for use by the Food and Drug Administration for other diseases, including cancer. The new drug combination is administered through pills taken orally.
Pancreatic tumors are characterized by mutations in a gene called KRAS. When KRAS is mutated in this way, it sends constant signals that promote abnormal cell division and growth in cancer cells. As a result, tumors grow out of control. At the same time, like all cells, pancreatic cancer cells must recycle their components to provide building blocks for new growth in an essential cell function known as autophagy. Previous studies to combat pancreatic cancer that were focused either on the role of KRAS or on impacting autophagy were not effective.
The longevity sector is showing signs of being taken more seriously. On Tuesday, Mehmood Khan, vice chairman and chief scientific officer of PepsiCo, announced he’s joining Life Biosciences, a startup dedicated to “age-reversal.” Khan will become the startup’s CEO and a member of its board of directors.

In the world of social media, this is just the most recent panic over children’s time on places like Youtube. however, it’s important to note that many of these things ARE just hoaxes. As the article mentions, this hoax plays on the guilt some parents have over how much time their children spend on computer screens.
The real “Momo Challenge” is the terror of parenting in the age of YouTube. Here’s the truth of what we know.
Researchers from the University of Luxembourg and the German Cancer Research Center have rejuvenated stem cells in the brains of old mice. The rejuvenated stem cells appear to improve regeneration in areas of damaged or diseased brain tissue.
A new way to model stem cells
A new study that was published in the journal Cell sheds light on why many stem cell populations in aged brains stop dividing and enter a dormant state known as quiescence. Quiescent stem cells have ceased to divide, so they no longer support the tissues of which they are part and play no role in regenerating damaged tissue by supplying fresh cells to replace losses. As we age, an increasing number of stem cells, not just in the brain, enter this quiescent state and impair our ability to heal injury and recover from diseases.
