Improving academic publishing through hypothesis registration, open reviews, and open data

Academic journals
[Source: http://www.wun.ac.uk/wun/research/view/world-class-universities]
There are three promising approaches for improve academic publishing:

1) Hypothesis preregistration. Currently, many academic studies gather large datasets and then search for trends/patterns within that dataset, without first stating their hypotheses. Such a post-hoc analysis, also called 'fishing', can lead to a Texas Sharpshooter falacy, which often arises when researchers have a large amount of data at their disposal, but only focus on a small subset of that data. The fallacy is characterized by a lack of a specific hypothesis prior to the gathering of data, or the formulation of a hypothesis only after data have already been gathered and examined. The fallacy occurs when the same data is used to construct and test the same hypothesis (hypotheses suggested by the data).

Suggested solution: Researchers pre-register their hypothesis, research designs, and analysis plans with a journal and publish them in advance, for example with the Open Science Foundation. Such a pre-registration allows for stronger explanatory and confirmatory research. An example of a journal that already practices hypothesis registration is Learning at Scale.

2) Many academic publications only publish the summaries of their data. This does not allow other researcher to verify the data analysis or re-use the dataset for further studies.

Suggested solution: Open data approaches allow researchers, whenever possible, feasible, and ethical, to make their dataset available for inspection and additional analysis. This also allows replication studies and an in-depth inspection by reviewers.

3) Reviewers and editors of academic journals often spend a lot of time reviewing submitted manuscripts. The academic publishing process is considered a 'dialogue' between the authors, the editor, and the reviewers. However, this dialogue happens usually behind closed doors (masked reviews) and the often substantial amount of work by the reviewers does not receive any official recognition.

Suggestion solution: Open reviews publish the peer review comments alongside the article. This gives the reviewers credit for their work and enables readers to judge for themselves how well the paper responded to the critique of peers. It could even be considered that reviewers and editors receive credit for the paper (similar to the credits in a movie that list all people who contributed in some form). Some journals even list reviewer reports with a separate DOI. Open review can also reveal the identity of authors and reviewers (rather than a single blind or double blind review). Open review could encourage a more authentic academic dialogue. Open reviews with a publication of peer review reports can contribute to greater transparency (see some examples here).

Advances in genetics class since your high school biology class

Over the past decades, the field of genetics rapidly developed, for example in the areas of inherited diseases, cancer, personalized medicine, genetic counseling, the microbiome, diagnosis and discovery of viruses, taxonomy of species, genealogy, forensic science, epigenetics, junk DNA, gene therapy and gene editing.

Joel Eissenberg, Ph.D., associate dean for research and professor of biochemistry and molecular biology at Saint Louis University School of Medicine summarizes major advances in genetics since the 1960s:

When Did You Go to High School?
If you took high school biology in the …
1960s, you learned about the structure of the double helix and how sequences of DNA encode amino acids.
1970s, you may also have learned about cloning and the potential for recombinant DNA.
1980s, your class may have covered the clinical use of recombinant human insulin for diabetes treatment and the advent of GMO foods.
1990s, your class may have studied the molecular basis for human genetic disorders, like cystic fibrosis.
2000s, your teachers likely described how the human genome was being sequenced.

What’s changed in genetics since your high school biology class?: The field of genetics has seen astonishing breakthroughs and the development of world-changing technologies in the past half century.

REALTO - the learning platform for vocational education that integrates school and workplace experiences

REALTO is a web- and mobile based platform that allows users to capture, annotate, and share experiences made at the workplace and at school. The goal is to integrate different forms of experiences through reflection.

Google releases digital notebook app for STEM education called 'Science Journal'

Google 'Science Journal' app
In collaboration with the Exploratorium, Google produced a free Android app, called Science Journal, aimed at helping young students record and analyze scientific experiment results. With this app, students can record data from sensors on their Android phones (or connected via an Arduino), take notes, observe, interpret and predict.

Supercomputer Watson suggests new recipes for adventurous cooks

Would you like discover new recipes? Created by a supercomputer? You can now ask Watson, IBM's supercomputer, to suggest an entirely new recipe for you that combines ingredients you might never have thought of putting together.

"Chef Watson" is an experiment to test if Watson could create entirely new and surprising recipes and ingredient combinations. After reading thousands of recipes and learning about food pairing theories and the hundreds of thousands of complex relationships between flavor compounds, Chef Watson has helped shape the public perception of the potential for cognitive computing.

You can try Chef Watson for free here or as an smartphone app.

Do-It-Yourself Gene-Editing Kit for biology education

Biophysicist and entrepreneur Josiah Zayner offers a do-it-yourself kit that allows you to cut, past, and string genes from one organism to another - on your kitchen table.

Moving genes from one organism to another used to be done only by big-budget labs. Three years ago, UC Berkeley developed the CRISPR gene-editing tool. CRISPR stands for 'Clustered Regularly Interspaced Short Palindromic Repeats', which refers to a protein(Cas9) that can use an RNA guide to make highly specific cuts in DNA. This allows unprecedented abilities to edit DNA. Zayer is the first to make the CRISPR tool kit available to the masses.

The DIY gene-editing kit allows altering bacteria and yeast (which can change color, fragnance, or living requirements). The DIY CRISPR kit is available for 120$: https://www.indiegogo.com/projects/diy-crispr-kits-learn-modern-science-by-doing#/
