    During the outbreak of novel coronavirus, cities are locked down and borders are closed. Science, on the contrary, is becoming more open. And this "open science” is already making a difference.

Soon after the epidemic started in China, a research team from Fudan University in Shanghai successfully sequenced （测定序列）the DNA of the virus. But they didn't keep the information to themselves. Instead, they placed the sequences on GenBank, an open-access data platform, so researchers around the world could download them for free and start studying the virus.

Due to this openness, pharmaceutical companies across the globe arc now able to work at the same time to develop a vaccine （疫苗）."There may be room for multiple different vaccines for different purposes and different age groups,” Amesh Adalja, a senior scholar at the Johns Hopkins University Center for Health Security in the US, told Al Jazccra. "The bigger menu we have of vaccines, the more resilient （有 适应 力的）we'll be against coronavirus outbreaks in the future."

Major drug companies around the world arc also sharing their study results. Remdesivir, a drug originally developed by US company Gilead Sciences to treat Ebola, is found to be promising in fighting against the novel coronavinis. Currently, two trials of the drug arc already underway in China, and the results might be available as soon as April, according to The Verge.

This openness in science is going to be even more important in the future. “With climate change, increasing globalization, and population shifts, epidemics will not go away, and might even become more frequent,” Dan Barouch, a Harvard Medical School professor, told Harvard Magazine.

He said, “No one group can do everything. It has to be a coordinated approach. But I do think that the world has a greater sense of readiness this time to develop knowledge, drugs, and therapeutics （疗法）very rapidly.”

Every epidemic is indeed a crisis, but it can also be a learning opportunity. One redeeming （补偿的）factor of the COVID-19 outbreak is that it is helping science adapt for the better.
