  • From the article:

    To demonstrate model collapse, the researchers took a pre-trained LLM and fine-tuned it by training it using a data set based on Wikipedia entries. They then asked the resulting model to generate its own Wikipedia-style articles. To train the next generation of the model, they started with the same pre-trained LLM, but fine-tuned it on the articles created by its predecessor. They judged the performance of each model by giving it an opening paragraph and asking it to predict the next few sentences, then comparing the output to that of the model trained on real data. The team expected to see errors crop up, says Shumaylov, but were surprised to see “things go wrong very quickly”, he says.

  • What they see as "bad research" is looking at an older cohort without taking into consideration their earlier drinking habits - that is, were they previously alcoholics or did they generally have other problems with their health?

    If you don't correct for these things, you might find that people who are not drinking seems less healthy than people who are. BUT, that's not because they're not drinking, it's just because of their preexisting conditions. Their peers who are drinking a little bit tend to not have these preexisting conditions (on average)

  • Here's an actual explanation of the 'sneaked reference':

    However, we found through a chance encounter that some unscrupulous actors have added extra references, invisible in the text but present in the articles’ metadata, when they submitted the articles to scientific databases. The result? Citation counts for certain researchers or journals have skyrocketed, even though these references were not cited by the authors in their articles.

  • Further, most of the times, it's simply infeasible to test the data in-depth. We're all humans with busy schedules and it is, unfortunately, not trivial to replicate experiments. If a reviewer feels more data is needed to support a claim, they can ask for a follow-up test or experiment, but it has to be within reason

    All arabica coffee is genetically similar: how can beans taste so different?

  • Seeing the edit, yes, but that is also wrong. As the first line of the link says, radiation therapy uses ionizing radiation and not microwaves

    It is possible to use microwaves for treating cancer (see https://www.bmc.org/content/microwave-ablation), but the two aforementioned methods do not use them (with the caveat that both "chemotherapy" and "radiation therapy" are very broad categories)

  • From the method section of the paper:

    Materials and Property Characterization. From a popular US chain store, two brands of baby food containers made of polypropylene and one brand of reusable food pouch with- out material information on the label were purchased. The selection of polypropylene containers was based on its widespread use in baby food packaging. These choices aimed to showcase diverse types of baby food packaging. The food containers and the food pouch were analyzed for their semicrystalline structure and thermal stability by DSC using a Q200 differential scanning calorimeter (TA Instruments, New Castle, DE). Briefly, a small sample weighing between 3 and 8 mg was taken from each container or pouch, placed in a DSC aluminum pan/lid assem- bly, and crimped with a press. The samples were heated and cooled at a rate of 10 °C/min under a nitrogen atmosphere, resulting in calori- metric curves that indicate the heat transfer to and from the polymer sample during the thermal cycle, which was used to monitor phase transitions.

T e c h n o l . 5 7 ( 2 0 2 3 ) 5 Transmission wide-angle X-ray diffraction (WAXD) of the reusable food pouch was performed at the 12-ID-B beamline at the Advanced Pho- ton Source (Argonne National Laboratory), using incident X-rays with energy 13.30 keV and a Pilatus 300k 2D detector mounted 0.4 m from the sample. WAXD patterns of the two plastic containers were acquired in reflection geometry with a Bruker-AXS D8 Discover equipped with a Cu Kα lab source (λ = 1.5406 A) and a Vantec 500 area detector. In all cases, the acquired 2D patterns were radially averaged to produce 1D intensity (I) vs scattering vector (q) plots

  • It is up to the shops whether they want to accept euro or not (or any other currency), but the official currency is kroner. I know that some supermarkets (Netto) used to gladly take euro in exchange for a horrible exchange rate
