By Nidhi Subbaraman A s marchers in the United States and around the world filled the streets over the past week to protest against police brutality and racial injustice, Black scientists grieved openly on social media, calling for action on racism in society and in science. Many stated ways in which institutions and colleagues, from collaborators to meeting organizers, could support Black scientists. Some pushed universities and scientific societies to release statements against racism. And several tweeted that the weight of the cur- rent events made it even harder for them to do their jobs in a profession that already margin- alizes women and people of colour — and Black scientists in particular. “I’m not there yet,” wrote Desmond Upton Patton, a professor of social work at Columbia University in New York City. “I’m struggling with kindness, forgiveness, empathy. I feel pushed to make decisions, go to meetings, and to ‘show up.’ I’m just not ready.” George Floyd’s death after being restrained and knelt on by police in Minneapolis, Minnesota, on 25 May, coupled with the killing of Ahmaud Arbery, Breonna Taylor and other Black Americans, sparked largely peaceful demonstrations across the country. The police response to some gatherings, which has included the use of chemical irritants and projectiles, made headlines and drew condemnation from civil-rights groups. Scientists are organizing, as well. As Nature went to press, hundreds were planning to stop their research on 10 June, as part of an academic strike in support of the larger Protesters have gathered across the United States and around the world to denounce racism and police brutality. An academic strike ran alongside marches and demonstrations worldwide.

The goal was “to hit pause, to give Black academics a break and to give others an opportunity to reflect on their own complicity in anti-Black racism in academia and their local and global communities”, said one of the groups organizing this event. Time-sensitive research on COVID-19 was able to continue. Many are exhausted by the stream of gut-wrenching news. Cassandra Extavour, an evolutionary and developmental biologist at Harvard University in Cambridge, Massachu- setts, said that reports of police brutality and killings alongside the systemic racism in her field test her will to stay in science. “Every time one of us is rejected, beat down, dismissed, ridiculed or murdered, I question why I am still in academia,” she wrote in a series of tweets. “I answer my question by asking myself if today will be the day that another black scientist leaves the field, is pushed out by the toxicity that we have to wade through every day so we can ‘be productive’ and ‘just think about science.’ I answer, ‘Not today.’” Critical messaging Over the past week, scores of universities and scientific societies joined organizations of every stripe in issuing statements about the civil unrest in the United States. Some faced criticism that they had missed the mark. For example, several chemists pointed out that the American Chemical Society (ACS) in Wash- ington DC left out key words, such as “Black”, “police brutality” and “racism”, in a statement released on 1 June, and took issue with the way that the statement criticized the use of vio- lence during the protests themselves. In doing so, they argued, the society missed the core drivers of the current movement and failed to acknowledge the pain its Black members were experiencing. According to some analyses, Black Americans are killed by police at more than twice the rate of white Americans. Glenn Ruskin, vice-president for external affairs and communications at the ACS, says that the society followed that “initial response” with a video message from ACS president Luis Echegoyen. “In this message, we condemn racism, stand in solidarity with our Black and Brown members and commit ourselves to using our resources to addressing issues of racism in all its manifestations,” Ruskin says. Many scientists challenged organizations to back up their statements with actions that support or elevate Black scientists, includ- ing sharing their figures on diversity and ensuring that they hire staff members from diverse backgrounds. Some spelt out steps that institutions could take. “Although it’s great that universities have made public statements condemning racism, it is important for those statements to include a specific list of anti-racist actions they’re planning to take to support their Black stu- dents, faculty and staff, such as increasing recruitment and retention efforts, supporting African American Studies programmes and anti-racism education, and providing more funding to support Black faculty and stu- dents,” says Jioni Lewis, a psychologist who studies discrimination and mental health at the University of Tennessee, Knoxville. Advice to allies Lesley Weaver, a cell biologist who is about to take up a post at Indiana University in Bloomington, suggested that scientific insti- tutions and societies should ensure that they include people from minority ethnic groups as editors, reviewers and authors of peer-reviewed papers; that they give students, staff and faculty members regular diversity and inclusion train- ing; and that they make diversity sessions at major conferences main events, rather than side acts that must compete for attention with concurrent sessions. “If academia wants to support Black scientists, they’ll train and support them instead of using black bodies for a number quota,” Weaver wrote. “If academia wants to support Black scientists, it won’t take another senseless death and uprising for it to be clear that Black lives matter.” Addressing her own field of cell biology, she suggested ending the use in research of HeLa cells, the extraordinary cell line that doctors at Johns Hopkins Hospital in Baltimore, Maryland, took and cultured without permission from Henrietta Lacks, a poor Black woman, in 1951. Jasmine Abrams, a behavioural scientist at Boston University School of Public Health in Massachusetts and Yale School of Public Health in New Haven, Connecticut, similarly tweeted ways scientists could be allies to Black colleagues: “Drop our names for special opportunities or hires. Post about our work on your social media. Cite us in your papers. Vote in favor of our contract renewals, tenure, and promotion.” Abrams continued: “Say some- thing (instead of secretly coming by our office later) in the faculty meeting, hallway, or class- room when a colleague or student says/does something implicitly or explicitly racist.” The challenges that Black scientists face — and that white colleagues are now seeing — aren’t new, she added. “Keep in mind that the plantation has been on fire for us and that for most, it is a legit daily struggle to do our work. We appre- ciate you reaching out, but we’d appreciate it more if you helped us put the fire out.” Amid the maelstrom, Bianca Jones Marlin, a neuroscientist at Columbia University, posted a video message addressed to other Black scientists. She spoke out loud something she wished she’d heard at difficult times in her past: “That your presence in science is important, that your purpose in science is seen,” she said. “I’m here to hear your stories. Because I get it.” Additional reporting by Giuliana Viglione “We appreciate you reaching out, but we’d appreciate it more if you helped us put the fire out.” Cryo-electron microscopy feat will allow the workings of proteins to be probed in unprecedented detail. REVOLUTIONARY MICROSCOPY TECHNIQUE SEES INDIVIDUAL ATOMS By Ewen Callaway A game-changing technique for imaging molecules, known as cryo-electron m i c ro sc o py, h a s p ro d u c e d i t s sharpest pictures yet — and, for the first time, discerned individual atoms in a protein. By achieving atomic resolution using c r yo - e l e c t ro n m i c ro sc o py (c r yo - E M ) , researchers will be able to understand, in unprecedented detail, the workings of proteins that cannot easily be examined by other imag- ing techniques, such as X-ray crystallography. The breakthrough, repor ted by t wo laboratories late last month, cements cryo-EM’s position as the dominant tool for mapping the 3D shapes of proteins, say scientists. Ultimately, these structures will help researchers to understand how proteins work in health and disease, and lead to better drugs with fewer side effects. “ There’s really nothing to break any more. This was the last resolution bar- rier,” says Holger Stark, a biochemist and electron microscopist at the Max Planck Institute for Biophysical Chemistry in Göt- tingen, Germany, who led one of the studies 156 | Nature | Vol 582 | 11 June 2020 News in focus © 2020 Springer Nature Limited.
