Scientists should leave the confines of the four walls of their laboratories and be proactively engaged in public policy decision-making processes.

According to astrophysicist Datuk Dr Mazlan Othman, scientists are in a better position to grasp a situation and make decisions based upon it.

"Scientists have already embraced science in their lives, so decision-making is very natural, almost second nature to them," she said.

While acknowledging that people from non-science backgrounds can be briefed about a certain issue which requires scientific analysis, she said it can never be the same like having a scientist whose second nature is sound decision making.

Even in matters which doesn't necessarily involve scientific analysis, having a person equipped with science background could make a difference, she implied.

She passionately advocated for more scientists to take up important positions in public services.

"I definitely advocate for more scientists to be actively involved in the public decision-making processes. Scientists themselves should ensure their active involvement in public policy making and civil services.

Science should be used for decision making across the board, in defence, health, education and not only in the environment or agriculture matters, she added.

"There should be more politicians who are scientists. More importantly, scientists cannot remain in the lab," Mazlan emphasised when contacted for her take on March for Science organised on Earth Day.

"March for Science in the US is seen quite political because of the impression that President Donald Trump is not supportive of science.

"However, March for Science doesn't have to be anti-establishment. The whole idea is about celebrating diversity in science and humanising the subject of science, putting a human face to it," said Mazlan who has dedicated most of her life in science exploration.

Talks and activities with regard to environmental issues and climate change is of central focus given the March is carried out on Earth Day.

March for Science is a global grassroots initiative that aims to uphold science as a pillar of human freedom and prosperity, and advocate for its role in enacting evidence-based policies that affect the present and future in the best interest of the public.
