When the tank failure was found on March 4, University Hospitals said the loss was expected to be only 2,000 specimens, or nearly half of the tank's contents. Many families held out hope that their eggs or embryos might have been saved.That was not to be. University Hospitals delivered the news that all contents of the tank had been lost -- more than 4,000 eggs and embryos -- in a letter to the 950 families dated March 26."We are heartbroken to tell you that it's unlikely any are viable," the letter said, adding that the tank had been turned off by an unknown person."An alarm should have been sent and received. We don't know who turned off the remote alarm nor do we know how long it was off, but it appears to have been off for a period of time. We are still seeking those answers," the letter said.In an emailed statement, the tank's manufacturer, Custom Biogenic Systems, denied allegations that the tank malfunctioned and made it clear that the alarm system was not its responsibility."Based upon our initial investigation, we have concluded that our equipment did not malfunction. The early stages of our investigation into this unfortunate incident indicate it was the result of human error," the statement said, adding that the company "did not design, manufacture, install, control, or monitor the remote alarm system that was reportedly 'off' during the time of this incident."In its letter to the families, University Hospitals also said that the tank had been undergoing preventive maintenance, with advice from Custom Biogenic Systems, for several weeks before the temperature rose. The autofill mechanism had quit working, University Hospitals said, and employees were filling the tank by manually pouring in liquid nitrogen.The manufacturer had been working with the hospital on how to re-enable the autofill feature, Custom Biogenic Systems said, but it claims that hospital staff had stopped its "recommended practice at least several days before the incident." When employees began filling the tank from the top, the manufacturer said, they made a serious error."The tank is not designed to be filled by liquid nitrogen being 'poured into the top of the tank,' as UH admits it was doing in its letter. This is an incorrect fill method and will cause liquid nitrogen to come into contact with the stored samples."In addition, by pouring liquid nitrogen into the top, the manufacturer said, the employees bypassed the system that monitors the levels in the tank."Rather, the read-out measures the level of liquid nitrogen in the liquid nitrogen reservoir, which was bypassed by UH's use of the 'container filling' method," its statement said. 2665

Zuckerberg will take the blame for Facebook's recent problems, according to prepared remarks released Monday by the House Committee on Energy and Commerce.He's expected to concede that Facebook "didn't do enough" to prevent a host of problems on its platform, such as fake news, foreign interference in elections, hate speech and data privacy."We didn't take a broad enough view of our responsibility, and that was a big mistake," Zuckerberg will say. "It was my mistake, and I'm sorry. I started Facebook, I run it, and I'm responsible for what happens here." 560
