         In 1859, Charles Darwin published the Origin of Species, laying the foundation for the theory of evolution through natural selection. Yet more than 150 years after that discovery and despite a large volume of scientific evidence supporting it, only 33% of the American population believes that humans evolved solely through natural processes. 25% of US adults believe that a supreme being guided evolution, and 34% reject evolution completely, saying that humans and all other forms of life have co-existed forever. Similarly, only 50% of American adults believe that global climate change is mostly due to human activity, with 20% saying that there is no evidence for global warming at all. A significant fraction of the public believes that there is large disagreement among scientists on evolution and climate change (the reality being there is overwhelming scientific evidence and consensus), and questions scientists’ motivations. Public skepticism about scientific evidence and scientists extends to other areas such as vaccination and genetically-modified foods.

Public mistrust in the scientific enterprise has tremendous consequences, not only for federal science funding and the advancement of science, but also for the implementation of effective policies to improve public and global health and combat issues such as global warming. In her keynote address at the 2015 annual meeting of the American Society for Cell Biology, Dr. Jane Lubchenko described the Science-Society ParadoxScientists need society, and society needs science. How then can we build public support for science, and improve public trust in scientists and scientific evidence?

Scientists need to be more actively involved in science outreach and public engagement efforts. Communicating science in its entirety, not just as sensational news, requires public understanding of science, and familiarity with the scientific process – its incremental nature, breakthrough discoveries (that don’t necessarily mean a cure), failures, and limitations alike. Who better to explain that to the public than scientists – skilled professionals who are at the center of the action? In a recent poll, more than 80% of Americans agree that scientists need to interact more with the public and policymakers. But two major hurdles need to be overcome.

Firstly, communicating science to the public is not easy. Current scientific training develops researchers to communicate science in written and oral formats largely to peers. As scientists become more specialized in their fields, technical terms and concepts (jargon) that they use frequently may be incomprehensible to non-experts (even to scientists outside their field). The scientific community would benefit tremendously from formal training in public engagement. Such training should be incorporated into early stages of professional development, including undergraduate and graduate schools. Both students and experienced scientists should be encouraged to make use of workshops and science communication opportunities offered by organizations such as AAAS, the Alan Alda Center for Communicating Science, and iBiology, to name a few. Secondly, federal funding agencies and philanthropic organizations should provide resources, and academic institutions should create avenues and incentives, for scientists to engage with the public. Both students and scientists should be allowed time away from their regular responsibilities to participate in public outreach efforts. Instead of penalizing scientists for popularizing science, scientists’ outreach efforts should be taken into consideration during promotion, grants and tenure decisions, and exceptional communicators rewarded. Trained scientist-communicators will be able to work better with their institutions’ public relations staff and science journalists to disseminate their research findings more accurately to a wider audience, and educate the public about the behind-the-scenes world of science that is rarely ever seen outside. Engaging with the public could also benefit researchers directly by increasing their scientific impact, and influence research directions to better impact society.

While increasing science outreach programs and STEM education may seem like obvious solutions, the science of science communication tells us that it is not so simple. The goals of science communication are diverse – they range from generating or sharing scientific excitement, increasing knowledge in a particular topic, understanding public’s concerns, to actually influencing people’s attitudes towards broader science policy issues. Diverse communication goals target a diverse audience, and require an assortment of communicators and communication strategies. Research has shown that simply increasing the public’s scientific knowledge does not help accomplish these various communication goals. This is because people don’t solely rely on scientific information to make decisions; they are influenced by their personal needs, experiences, values, and cultural identity, including their political, ideological or religious affiliations. People also tend to adopt shortcuts when trying to comprehend complex scientific information, and believe more in what aligns with their pre-existing notions or with the beliefs of their social groups, and what they hear repeatedly from influential figures, even if incorrect. Effective science communication requires identifying, understanding and overcoming these and other challenges.

The National Academies of Sciences, Engineering, and Medicine convened two meetings of scientists and science communicators, one in 2012 to gauge the state of the art of research on science communication, and another in 2013 to identify gaps in our understanding of science communication. The resulting research agenda outlines important questions requiring further research. For example, what are the best strategies to engage with the public, and how to adapt those methods for multiple groups, without directly challenging their beliefs or values? What are effective ways to communicate science to policymakers? How do we help citizens navigate through misinformation in rapidly changing internet and social media? How to assess the effectiveness of different science communication strategies? And lastly, how do we build the science communication research enterprise? Researchers studying communication in different disciplines, including the social sciences, need to come together and partner with science communicators to translate that research into practice. The third colloquium in this series will be held later this year.

Quoting Dr. Dan Kahan of Yale University, “A central aim of the science of science communication is to protect the value of what is arguably our society’s greatest asset…Modern science.” As evidence-based science communication approaches are being developed further, it is critical that scientists make scientific dialogue a priority, and make use of existing resources to effectively engage with the public – meet people where they are – and bring people a step closer to science – why each person should care – so that ‘post-truth’ doesn’t go from being merely the word of the year to a scary new way of life.

How to Make a Valuable Postdoctoral Experience: Updating the Model

leave a comment »

By: Aparna Kishor, MD, PhD

       To an outside observer, the scientific enterprise in the US appears to be thriving. The 2016 budget of the National Institutes of Health (NIH) was $31.3 billion. Of this, about 80% was distributed to research projects performed extramurally, pointing to the fact that hundreds of thousands of researchers nationwide, established scientists as well as trainees, benefit from the funding. Although the numbers are somewhat murky, it is likely that over 50% of graduate students and postdoctoral researchers (postdocs) receive some federal funds.

A more granular view of the reality of modern scientific training reveals its true complexity. In The Postdoctoral Experience Revisited, a report on postdoctoral training in the US, the National Academies argue that there are serious issues in the way we train our young scientists today, including those having to do with recognition and compensation, mentorship, and career advising. Fundamentally, although the US has more postdocs than ever before, does this serve the individuals involved?

First some context. For those committed to a career in the biological sciences, the first stage of training is graduate study to acquire technical and field-specific skills, culminating in a PhD. Traditionally, the second is the postdoctoral stage, which provides additional technical experience and preparation for a future career, ideally culminating in a research position. In the US, approximately 65% of those with graduate degrees in the life sciences continue on to a postdoc which is the field with the highest rate of entry. The second highest is in the physical sciences, with only 50%. Although the quotidian experiences of the two may be similar, the graduate and postdoctoral stages are actually quite different, particularly since graduate training tends to have formal requirements and expectations while postdoctoral training, does not. This framework also has distinct benefits for the principle investigators (PIs). A major one is economic: junior scientists are a willing, and in the case of postdocs, highly trained, source of cheap labor (more on this below). On occasion, the work may be done at no cost to the PI if the trainee has funding from another source, although this is becoming proportionally less common.

When the postdoctoral arrangement was established in the early part of the 20th century, the training periods were typically 1-2 year stints in a lab to learn additional skills and consolidate connections in the field. After this, the young researcher would generally transition into an academic position. In the 1970’s, close to 55% of postdocs held tenure or tenure track faculty positions 6 years after completion of their graduate studies. Now, when a postdoc plans for his or her next career move, the situation is not so simple and this has aroused the concern of the National Academies. Partly, the difficulty is due to the number of available academic positions being outstripped by the number of postdocs in the pipeline. Data from 2006 show that only 33% of postdocs had faculty positions 6 years after graduate school and only half of those were tenured or tenure-track. The rest of the explanation lies in the fact that the landscape of the scientific enterprise has evolved.

Most obviously, the demographics of the postdoc community are markedly different from those in the early 20th century resulting in different needs for trainees. As of 2014, women were receiving close to 50% of all life science doctorates awarded in the US. Gender parity at graduation has not carried through to the faculty level (where only approximately 25% of tenured faculty are women). Among the many potential causes for this decline, one is that many women leave the academic track due to the challenges in balancing a career with raising a family. Nonetheless, there are more women at all levels in the sciences than before, indicating that retention may be increased by supporting women during the time that their children are young. Holders of temporary visas comprise another important population, but there are very few concrete data pertaining to them. They obtain close to 25% of all doctorates in the biological sciences, and 80% of those who have jobs after graduation stay in the US. With this, there is significant flux into the system at the postdoc level. As a result, upwards of a third of all biomedical postdocs in the US are foreign nationals primarily from India and China. Since these people have never been counted, the best way to help them meet their goals and the role they play in the US scientific arena are undefined.

Another important change is that postdoctoral training periods have lengthened from 1-2 years to around 4 years. For those who want the training, this timeline extension is believed to be a necessary sacrifice in order to gain entry into the competitive world of academia. Unsurprisingly, the percentage of PIs under 36 has fallen from 18% from 1980 to 3% in 2010. For established investigators, the longer training times are advantageous. Postdoc salaries at research institutions generally amount to less than the combined tuition-plus-stipend package offered to graduate students. After a few years, a postdoc may conduct research at a level equivalent to that of permanent scientific staff but at a fraction of the cost – postdocs pull in anywhere from $40,000 to $49,000 a year, while staff will have full benefits and a salary closer to $80,000 a year. Given this, the challenge is to make a prolonged training period valuable, feasible, and non-exploitative for all who choose it.

Finally, there is growing evidence that a postdoc may not be the right choice for everyone. Most junior scientists feel limited by the now-classic dichotomy between pursuing research in academia and industry. The reality is that many other career options exist, although some are a step or two removed from pure research. These are in areas like consulting, intellectual property, and science policy. Some jobs will provide entry-level incomes greater than a postdoc, and may even lead to career prospects that are more secure than that in research. Entry level salaries for some careers in industry begin at $70,000 and mean salaries in industry can be $40,000 more than that in academia, and the age at first non-academic job is lower than that for academics. Critically, for those wishing to optimize some of these other aspects of their professional advancement, a postdoc may be unnecessary.

Taken together, these developments indicate a need to change the culture surrounding the postdoc. The essence of the National Academies’ recommendation to improve the postdoctoral experience is that the entire scientific community must treat it as a valuable training opportunity instead of basic employment. To this end, the minimum postdoctoral salary should be increased, even beyond the current $47,484.  The improved economics for trainees will have a number of benefits: it will place more value on these individuals, limit the number of postdocs an investigator may hire, perhaps encourage more women to stay in research, and make positions more competitive, lessening their use as a default employment option. Postdocs should also be encouraged to receive individual funds as proof of independence. There is some evidence that postdocs on their own fellowships are more satisfied than those funded by their lab, although it seems likely that people more committed to a career as a researcher are the ones most likely to apply for fellowships. Additionally, those who receive early career grants are more likely to receive independent investigator grants and faculty appointments. Finally, there is an argument for more staff positions as a measure to keep postdoctoral opportunities as dedicated training experiences.

For now, it is important for each researcher to decide whether it is in his or her best interest to embark on the postdoctoral route. Fortunately, career advising is increasingly available to trainees at all levels and the NIH and other groups have issued mentorship guidelines for postdocs. Overall, the entire scientific community must assist in returning value to a postdoc and in meaningful career development for all trainees.

Brexit and Science

Scientists Need To Wake Up to the Opportunities of Brexit

The decision of the United Kingdom to leave the European Union last July has raised numerous concerns about the future of science within the UK, most notably regarding access to EU funding, such as Horizon 2020, and the effect of new immigration controls on non-UK researchers and students. A recent House of Lords report has called for the UK government and scientists to come together and address these concerns.

Firstly, the government should engage scientists throughout the negotiation process and not just in regards to funding. Leaving the EU will require reworking and harmonizing numerous consumer protection, environmental and manufactory laws, for which technical advice is indispensible. The report welcomes the recent increase in science funding from the government, but states that any loss in EU funding should be compensated for. They recommend that both the Department for International Trade (DIT) and the Department for Exiting the European Union (DExEU) appoint scientific advisors immediately.

Secondly, the report calls for the scientific community’s voice to be heard alongside that of business during the negotiations. The UK’s relationship with the EU has been consistently harmonious in regards to research, providing a solid point of agreement amongst more difficult negations.

Thirdly, the UK should explore research collaborations beyond the EU. The report suggests this could be realized if the UK were to offer to host a large, international research facility comparable to the Crick Institute or the Diamond Light Source. They also highlight the potential for industrial collaboration and reform of R&D taxation which would not be possible within the EU.

Immigration remains a key concern in regards to Brexit, with many EU scientists in the UK uncertain of their futures with many now considering leaving. The report emphasizes the need to attract and retain the best international talent going as far as to suggest 10 year research grants and support for immediate family for foreign scientific leaders. They also call for the government to clearly state how immigration laws will affect researchers coming to work in the UK, and that the number of international students coming to study in the UK should not count against any immigration targets.

Biomedical Research

The New Face of US Science

A recent analysis has found that the face of biomedical research has changed considerably over the last few decades. The study, which pooled data on holders of PhDs working as biological or biomedical scientists from the Survey of Doctorate Recipients and the American Community Survey, found that the doubling of NIH funding between 1998 and 2004 had a profound effect on the demographics of the scientific workforce. The authors classify scientists who entered the workforce around this time (i.e. under 40s) as a new cohort, giving them the not so snappy title of “doubling boomers”.

The 1998 to 2004 funding increase meant the number of PhD graduates increased significantly during this time, but the lack of growth in academic positions and funding cuts mean that only 1 in 5 still work in academia (as compared to 1 in two in 1990). For the aspiring academic this may seem like terrible news, but the report also found that the majority of biomedical PhDs now work in the private sector where they earn around $30,000 more a year than their academic peers and report lower pressure to publish publications.

The work force is more diverse than ever, with almost half of young biomedical scientists coming from US minority races. The largest growth has come from Asian ethnic groups, followed by a modest increase in researchers from Latino backgrounds. However the proportion of black scientists showed only a minor increase. These demographics should be borne in mind when devising recruitment and retention strategies to make the workforce more egalitarian.

Finally they found that scientists under 40 are likely to have children around the time they will be applying for their first grant. This is particularly problematic for female scientists, who the study found were less likely to have a stay-at-home spouse who can shoulder household responsibilities. The current academic career trajectory does not take in to account these important differences.

Despite many of these problems being discussed anecdotally for quite some time, the systems for tracking the fates of holder of PhDs after they graduate remain lacking, especially for those who leave academia. The authors insist that better and more transparent data is critical for designing new policies to assist young researchers.
