Human stem cells cloned for the first time

An international team of scientists announced today that for the first time ever, they were able to create new human stem cells by cloning older, fully mature human cells. The process cannot be used to create full human clones, as the scientists involved were quick to point out, but it does allow for cells to be grown to fit specific functions within an individual's body ? resulting in new, patient-specific liver cells or heart cells that actually pulse on their own, for example.

Eventually, scientists hope to refine the process to the point it could be used to help treat disease and even create whole custom organs, but that is likely to be several years away at the earliest. "While there is much work to be done in developing safe and effective stem cell treatments, we believe this is a significant step forward in developing the cells that could be used in regenerative medicine," said Shoukhrat Mitalipov, the leader of the research team and a senior scientist at the Oregon National Primate Research Center (ONPRC), in a news release.

The research team was led by scientists at the Oregon Health & Science University, who used a technique similar to the one that created Dolly the sheep, the first mammal cloned from adult cells, back in 1996. In a basic sense, this method involves taking an adult cell from a patient's body, sucking out the central portion containing DNA (the nucleus), then injecting this material into an empty egg cell donated by another human volunteer. The genetic material from the adult cell tells the empty egg cell what type it should mature into.

    • My external monitor suddenly isn't working and found out on my device manager that AMD radeon graphics has a "code 43"

      According to Microsoft, Cause: One of the drivers controlling the device notified the operating system that the device failed in some manner.   https://support.microsoft.com/en-us/topic/error-codes-in-device-manager-in-windows-524e9e89-4dee-8883-0afa-6bca0456324e

      This looks awesome, I will request access via Steam later this afternoon!
    • How do you future-proof a home or small office network?

      By Circaflex · Posted

      Personally, I’ve found that it’s usually worth investing in the infrastructure you don’t want to replace later, especially cabling. Running Cat6A (or better, depending on your needs) during an upgrade is relatively inexpensive compared to having to re-cable a few years down the road. For switches I try to balance current specs with realistic growth. If my budget allows it Ill choose switches with higher uplink speeds which leaves room for expanding later on, but I don’t necessarily overspend on access ports if the endpoints won’t benefit from them anytime soon. One lesson I’ve learned is that planning for scalability pays off. It’s much easier to add devices, VLANs, or higher-bandwidth workloads when your network infrastructure already supports it than to replace hardware later.  What is your budget like?

      I hate the term, "future-proof." We saw it back in the 90's / 2000's, if not before. You cannot future-proof anything, since there is no definition of how far into the future you plan on prepping for. Best idea is to tell us what you currently have and what its use is at the moment, and we can then offer ideas about some areas that might need an upgrade and other areas that can be left alone.
    • Celebrating Windows XP's 25th anniversary this year

      By Nick H. · Posted

      I can agree that it is being used in a small capacity. I worked for a company where their engineers still used XP, and when asked why it was because their sensor software wasn't compatible with newer operating systems and the software was discontinued so they couldn't upgrade the software. Given that the sensors were still in use by companies, they had to continue using XP to support the sensor, otherwise the price to the company would have gone into the millions or billions. Our response was simple: Ok, you can keep the XP machine. But we're removing it from the network. "But then it can't access the Internet or folder shares!" Yup, kinda the point. If someone wants to continue using an unsecure OS they can do, I have no problem with that. But it should be isolated. Simple. I had a fight with a guy in the engineering department for weeks before he finally relented. But we digress.   What do I plan on doing to commemorate the anniversary? Nothing. I have fond memories of the OS, but at the end of the day it's just an OS. If I had some time I might see if I could install it on my Raspberry Pi for a laugh. But my reflex memory with today's OS ideas would probably get me frustrated and I'd uninstall it after 5 mins.
