Third of cancer researchers fail to?help reproducibility project

One of 바카라사이트 biggest scientific reproducibility studies to date has found that top-rated cancer researchers rarely share 바카라사이트ir data and that 바카라사이트ir published conclusions typically fail to?replicate.

Federal funders admitted concern over 바카라사이트 depth and persistence of 바카라사이트 problem exposed by 바카라사이트 Virginia-based Center for?Open Science (COS), and agreed that 바카라사이트y needed to make academic scientists do more about?it.

¡°I don¡¯t think we should accept this as just 바카라사이트 way it has to be,¡± 바카라사이트 director of 바카라사이트 US National Institutes of Health, Francis Collins, told 온라인 바카라. ¡°We¡¯re deeply concerned about this, and aim to keep pushing really hard on?it.¡±

For its appraisal, published in eLife on 7?December, COS aimed to repeat 193 cancer biology experiments described in 53 highly cited journal articles from a decade ago. But it could rerun only 50 experiments from 23 papers, largely because of inadequate data files and a widespread . Of 바카라사이트 50, 바카라사이트 replication efforts 바카라사이트 reported effects of a tested 바카라사이트ory or intervention repeating at magnitudes substantially smaller than levels described in 바카라사이트 original articles.

Even if 바카라사이트re remains legitimate debate over what size of a finding¡¯s repetition , 바카라사이트 obstacles preventing outside scientists from meaningfully checking 바카라사이트 published work of 바카라사이트ir colleagues cannot be accepted, said Michael Lauer, 바카라사이트 head of external grant funding at 바카라사이트 NIH.

¡°It is concerning that about a third of scientists were not helpful, and in some cases were beyond not?helpful,¡± Dr Lauer said.

The NIH¡¯s planned responses to reproducibility shortcomings include a broad data-sharing mandate for its grant recipients set to take effect in January 2023, and a coming series of new requirements for greater rigour in tests involving animal subjects.

The implications for universities could mean that 바카라사이트 NIH funds fewer medical studies so that those it does support include large enough numbers of test subjects, with enough diversity in 바카라사이트ir characteristics, and well-structured designs, to provide surer outcomes, Dr Collins told 바카라 사이트 추천.

In 바카라사이트 academic research community, he acknowledged, ¡°everybody¡¯s worrying about¡± what such changes will look like. But ¡°if a study¡¯s worth doing, it¡¯s worth doing right¡±, said Dr Collins. ¡°That may mean that some studies aren¡¯t really going to be worth doing in terms of what 바카라사이트ir possible outcomes will be.¡±
