A new shot literally regrows knee cartilage.
Researchers at Stanford Medicine have identified a novel strategy to regenerate articular cartilage in knees and potentially prevent or treat osteoarthritis (OA).
The method targets 15-hydroxyprostaglandin dehydrogenase (15-PGDH), an age-related enzyme—or "gerozyme"—that accumulates in aging tissues and drives degeneration.
In aged mice, small-molecule inhibitors of 15-PGDH, delivered systemically or via intra-articular injection, promoted cartilage thickening and regeneration of functional hyaline articular cartilage.
This occurred without recruiting stem or progenitor cells; instead, existing chondrocytes underwent transcriptional reprogramming to a youthful state, with reduced populations of inflammatory and hypertrophic/degradative cells and expanded matrix-producing articular chondrocytes.
The inhibitors also reversed natural age-related cartilage thinning, improved joint function, and—when administered after simulated ACL injuries—strongly mitigated post-traumatic OA progression and associated pain.
Human OA cartilage explants from total knee replacements responded similarly in vitro, showing decreased degradation markers and evidence of new articular cartilage formation.
Given that an oral 15-PGDH inhibitor has already completed Phase 1 safety trials for age-related muscle atrophy, the findings open a path toward disease-modifying, regenerative therapies that could delay or obviate the need for joint replacement surgery.

BREAKING: Turkish Foreign Ministry:
We strongly condemn the UAV attacks carried out today in Azerbaijan’s Nakhchivan Autonomous Republic.
We once again emphasize that attacks targeting third countries in the region and increasing the risk of the war spreading must come to an end as soon as possible.
Türkiye will continue to stand by Azerbaijan, as it always has.

The cost of shipping crude oil from the US to Asia is skyrocketing:
It now costs over $29 million to hire a supertanker to take 2 million barrels of crude from the US Gulf Coast to China, the highest on record.
Shipping rates have DOUBLED in just two weeks.
This means shipping alone costs ~$14.50 per barrel, or a record ~20% of the oil price at current WTI levels of ~$75.
The cost of a supertanker as a percentage of the WTI crude oil price has quadrupled since August, when it was ~5%.
This comes as the ongoing war in the Middle East has effectively shut down traffic through the Strait of Hormuz, forcing Asian buyers to turn to US barrels.
Many supertanker bookings to load crude from the US Gulf Coast have already been canceled over the last 24 hours as costs become unsustainable.
Oil supply chains are under historic stress.
