multi-line billing question

so i bought some of the multi-month iphone 16e promos. it charged me $140-$150 each to add this as a line with other phones on supreme plan (180 minus one month of multi-line discounts)... but then it pools it all together as a credit and they come off month by month

so like right now i have $300+ in credit and its deducting the three lines at the expected $110/mo... so ill actually get more than 3 mos out of those $140 and $150 payments.

so if i already have this prepaid, and cancel one of the lines, what happens? obviously the monthly bill will go up unless i replace it with a different line/phone, but when cancelling a line, does any portion of the prepayment disappear?

scientists 3D print windpipe using patient's own cells

In a major medical breakthrough, South Korean scientists have successfully implanted the world’s first 3D-printed windpipe made entirely from a patient’s own cells.

The groundbreaking procedure was performed on a woman who had lost part of her trachea after thyroid cancer surgery. Using advanced bioprinting technology, researchers created a personalized windpipe by combining the patient’s own living cells with a biodegradable scaffold.

Because the implant was made from her own biological material, her body recognized it as natural tissue. This resulted in zero rejection and eliminated the need for lifelong immune-suppressing drugs — a common requirement in traditional organ transplants.

The successful integration marks a significant step forward in regenerative medicine and personalized organ replacement.
