Apple Faces Premium DRAM Costs as Long‑Term Agreements Expire
Wccftech reports that Apple’s long‑term supply contracts for DRAM are set to run out in early 2026, opening the door for Samsung and SK hynix to charge “premium” prices for the memory chips that power its flagship devices. Analysts fear the added expense could pressure Apple’s margins unless the company renegotiates or diversifies its supply chain.

SK Hynix Warns of DRAM Supply Lag Through 2028
According to Wccftech, SK Hynix’s internal analysis projects a persistent shortfall in “commodity” DRAM production that will outpace demand until at least 2028, tightening an already strained market. The forecast underscores why manufacturers are bracing for higher component costs across PCs, servers, and mobile devices.

Smartphone Makers May Re‑Introduce 4 GB RAM Devices Amid Shortage
Wccftech highlights a new industry report suggesting that the ongoing DRAM crunch could force flagship smartphones to pause the migration to 16 GB RAM, while entry‑level models might revert to 4 GB and bring back features like microSD expansion to offset memory constraints. The shift would mark a rare step back in mobile hardware specifications.

Space Medicine Advances Pave the Way for Human Missions to Mars
The Scientist explains how researchers are developing preventive medication regimes, pressurized suits, and radiation monitoring to safeguard crews on long‑duration missions, building on a 378‑day Mars simulation that tested habitat management and robotic operations. These efforts dovetail with NASA’s Artemis lunar‑return roadmap, which aims to establish a lunar foothold as a proving ground for eventual Mars settlement.
