The Long Quest for Artificial Blood

3 months 1 week ago
Scientists are making significant advances in developing artificial blood substitutes, with two promising approaches emerging in 2025, the New Yorker reports. At the University of Maryland School of Medicine's Center for Blood Oxygen Transport and Hemostasis, researchers are testing ErythroMer, a synthetic nanoparticle that mimics red blood cells' oxygen-carrying capabilities. Simultaneously, the UK's National Health Service is conducting the first human trials of lab-grown blood cells. These developments address critical blood shortages - of the 38% of Americans eligible to donate, less than 3% do so regularly. Traditional donated blood also has significant limitations: platelets last only 5 days, red blood cells 42 days, and all require careful refrigeration and blood-type matching. DARPA awarded $46 million in early 2023 to develop ErythroMer, seeing potential for battlefield medicine where traditional blood storage isn't feasible. The synthetic blood can be stored as a powder and reconstituted when needed. There are still a lot of challenges, the report adds. The lab-grown blood currently costs about $75,000 per syringe compared to around $200 for a pint of donated blood, and production is limited to small quantities.

Microsoft's Windows 10 Extended Security Updates Will Start at $61 per PC for Businesses

3 months 1 week ago
Microsoft will charge commercial customers $61 per device in the first year to continue receiving Windows 10 security updates after support ends, The Register wrote in a PSA note Wednesday, citing text, with costs doubling each subsequent year for up to three years. Organizations can't skip initial years to save money, as the updates are cumulative. Some users may avoid fees if they connect Windows 10 endpoints to Windows 365 Cloud PCs. The program also covers Windows 10 virtual machines running on Windows 365 or Azure Virtual Desktop for three years with an active Windows 365 subscription.
