    RT @CRISPR_LuCas: IVF is safe. This kind of fearmongering based on observational associations has been going on for decades. I worry that someone who needs IVF to build a family will see this study and decide against it because of misleading claims about cancer risk. Obvious issues with this study: - Inadequate control for parental characteristics and underlying infertility, which could explain the associations (the biggest issue with any of these studies is that people seeking IVF are usually older or have other health problems). - The dramatic risk estimates rely on tiny numbers of cancer cases (just 23 after frozen embryo transfer). - Dozens of statistical comparisons without correcting for multiple testing, increasing the likelihood of false positives. - Frozen embryo transfer and ICSI are overlapping procedures, making it difficult to attribute risk to either. - Uses data from 1996–2012, before many modern IVF techniques became standard. Meanwhile, a 2023 Dutch study following 89,000 children for a median of 18 years found no overall cancer-risk increase after ART when comparing families with infertility. A 2025 meta-analysis also found no increase using subfertile comparison groups, and no difference between fresh and frozen embryo transfer.
    Josh Wood @J_K_Wood
    A 20-year study of a million children found that kids conceived by IVF frozen embryo transfer had double the cancer rate. 84% of US IVF transfers now use frozen embryos. Danish researchers followed every child born in Denmark from 1996 to 2012 for up to 20 years. The study was published in JAMA last week. Children conceived without assisted reproduction developed cancer at 18.3 per 100,000 per year. After frozen embryo transfer, the rate was 41.1. After ICSI, where a single sperm is injected directly into the egg, it was 27.9. After frozen transfer, leukemia ran more than twice as high. The only method that showed no increase was a fresh embryo, never frozen, created by placing eggs and sperm together in a dish. That version is now the exception. In 2021, 84% of US IVF transfers used frozen embryos and 78% used ICSI, according to the CDC. Compared with children of women with a history of infertility who conceived without treatment, the frozen embryo risk stayed at more than double. In the authors' words, the results suggest "procedure-related, rather than infertility-related, factors." This is not the first time the pattern has shown up. A 2019 JAMA study of the same Danish children at 11 years found it too. A 2022 study of 2.3 million children in Taiwan found those conceived through assisted reproduction had 58% higher cancer risk, "mainly owing to leukemia and hepatic tumor." The absolute risk is small, and most of these children will never get cancer. The Danish children were conceived with older freezing methods, and the authors warn the results "may differ for contemporary protocols." Nobody yet has long-term data on IVF as it is done today. Children conceived with today's methods won't have 20 years of data until the 2040s, so today's IVF children are, in effect, the trial. Parents deserve to hear these numbers before they sign the consent form, because their child is the one who will carry the risk.

    RT @levie: If you wanted to know all the jobs that AI will produce, look no further than cybersecurity. This is going to become one of the biggest investment areas for enterprises going forward. And even as the work becomes more agentic and autonomous you will need more talent to point the agents at the most critical work, review findings, patch systems, respond to incidents, and more. Lots of opportunity right now for the systems that protect data and enterprises, as well as the professionals that are deploying them and protecting organizations. It’s going to only get more wild out there.

    Meta’s Muse is blocked at Schwab. Its CEO asks who’s liable if an agent moves money. When an AI agent makes a mistake, causes financial harm, exposes private information or breaks the law, who's responsible? The answer isn't complicated. AI agents aren't legal persons. They're software created, configured, authorised and deployed by people and companies. US law has recognised autonomous software since 2000. The federal E-SIGN Act explicitly defines an "electronic agent" as software capable of acting without human approval at the time of each action. The law recognises transactions conducted through automated systems. If a company gives an AI agent access to confidential information, financial accounts or computer systems, that company remains responsible for the decisions it made about access, permissions, security controls and supervision. Whether it must compensate someone depends on the applicable law, contracts and circumstances. If an agent transfers money without authorisation, accesses confidential records or attacks another company's infrastructure, investigators should examine who configured it, what instructions it received, what permissions it had, who authorised those permissions and what its activity logs show. Schwab can't blame an agent for acting independently, any more than they can blame an Excel macro. The difference between an AI agent making a mistake and a company being legally liable for that mistake is important. But neither changes who's responsible for deploying the software.

    RT @kevinace: My @grok @bot found a clinical trial for my stage 4 lung cancer an hour from my house. I never would have known about it on my own. I'd been interested in a trial for a new ALK drug called TRI-611, but not if it meant flying across the country over and over. In September the trial added the University of Cincinnati as a site, and my bot caught the change. It also flagged an eligibility question for me to take to my oncologist. Before this I was passive. Maybe I'd stumble on something on X, maybe my oncologist would mention something (he hasn't), and my ALK+ patient group on Facebook was probably the most reliable source. Nothing was guaranteed, and I definitely wasn't hearing about trials adding new locations. Now it checks for me every morning, and I'm tracking more than 25 options, from personalized vaccines to next-gen ALK drugs, sorted by how relevant they are to me and when they'd make sense. The whole game is curation...the more it knows about your diagnosis, the more it finds signal instead of noise. 1. Teach it your diagnosis. Mine knows my cancer type, stage, every treatment I've had, my biomarkers, and how far I'm willing to travel. Trials include or exclude people based on exactly these things. 2. Tell it what to do. Mine checks clinical trial listings, FDA decisions, conference abstracts and company news, compares it all against the day before, and only pings me when something new and sourced shows up. 3. Review what it finds. I read the source, then run it past Grok, which both know my history, to decide whether it's useful and when. Then it goes into my tracker in Notion (below). More on that part in another post soon. It gives me hope, too. Even when I'm not eligible, seeing new companies form and new trials open every week reminds me how fast this field is moving. I turned my setup into a template so any patient or caregiver can build their own. It asks about the diagnosis, travel limits, and where to keep results, then builds the watch around the answers: Thank you @SpaceXSI @elonmusk for building this.
