Dr. David Shusterman, a board-certified urologist who was not involved in the study, told Newsweek: “The study suggests male reproductive aging may not always be a fixed, irreversible process.”

Dan Barry: Don’t Let Anyone Tell You That You Can’t Reach Your Dreams
For fifteen years, NASA told Dan Barry no.
He kept applying. Then he flew three shuttle missions, walked in space four times, and made two trips to the International Space Station. On the mission that didn’t go there, he was outside the orbiter rehearsing how to build it.
In 2011, I ambushed him with a camera at Singularity University and got 20 minutes.
Dan is not just an astronaut. He holds a doctorate in electrical engineering from Princeton and a doctorate in medicine from Miami, and he left NASA in 2005 to build #robotics for people with disabilities. So when our conversation turned to #ArtificialIntelligence, and specifically to what happens when we arm it, he was not speculating. He was describing machines he understood from the inside.
Armed drones were already flying in 2011. What nobody had done yet was hand the machine the decision to fire. Fifteen years on, that line is thinner than most people realize.
We also got into Asimov’s three laws, the Turing test, his 109 project to improve a billion lives in a decade, and whether we survive the #Singularity at all.
Striped or checkered? Magnetic field influences competing electronic patterns in a graphene-like quantum material
In most everyday materials, such as copper, silver and silicon, the behavior of electrons is relatively predictable. In quantum materials, however, electrons can interact in complex ways, giving rise to collective electronic states with remarkable properties. Understanding how these states emerge—and, ultimately, how to control them—is one of the central challenges in quantum materials research.
Now, researchers from the Okinawa Institute of Science and Technology (OIST) and Hiroshima University have discovered that a small magnetic field switches the layered quantum material CeTe₃ between competing electronic states that appear as striped or checkerboard patterns.
Published in Nature Communications, the work reveals how magnetism can reorganize a quantum material’s entire electronic state.
Obesity-derived metabolites modulate anti-tumor immunity in the tumor microenvironment: from mechanisms to clinical applications
The tumor microenvironment (TME) is increasingly understood as a metabolically dynamic ecosystem in which local metabolite availability, composition, and trafficking shape immune cell fitness and therapeutic responsiveness. Against the backdrop of the global obesity epidemic, obesity-associated systemic metabolic dysregulation has been implicated in tumor initiation and progression and may also influence the immune contexture and treatment responsiveness of tumors. This Review examines how obesity-derived systemic metabolites may modulate anti-tumor immunity and influence cancer immunotherapy, with particular emphasis on pathways involved in metabolic reprogramming and TME remodeling. We further discuss intervention strategies spanning (i) upstream metabolite generation, (ii) systemic-to-local trafficking into the TME, and (iii) direct functional antagonism within the TME.
This is one of the biggest stars in the Universe. Scientists say it looks like it’s about to explode
Star WOH G64 could be about to explode, and its extreme transition offers a rare opportunity to witness stellar transformations in real time.
The Surprising Evidence our Universe is INSIDE a Black Hole
What if everything we know — every galaxy, every star, every atom — is actually inside a black hole? In this video, we explore the fascinating possibility that our entire universe could exist within a black hole embedded in a larger “parent” universe. This idea isn’t science fiction; it arises from real solutions to Einstein’s equations in general relativity and from modern efforts to connect gravity with quantum mechanics. We examine what physics predicts happens inside a black hole, how space and time behave at an event horizon, and why the Big Bang might resemble the birth of a black hole from the outside.
We also explore the deeper implications of this theory: whether a collapsing star in another universe could create a new expanding universe on the inside, how spin and entropy might relate to cosmic expansion, and what this could mean for the concept of a multiverse. Could every black hole be the seed of a new universe? And if so, what does that say about where we came from and the true structure of reality? This is one of the most mind-bending ideas in cosmology — and it challenges our very notion of what “inside” and “outside” even mean.
