PARIS

More from Paris

The Paris march is taking its time, stopping at various research and higher education landmarks for speeches along the way. After a lengthy pause at the Université Pierre et Marie Curie, we're now at the Collėge de France, where speakers lament the Trump administration's views on climate change and the French government's broken promisies. Organizers say there are between 4500 and 5200 marchers, which seems about right. The march is relaxed but a bit subdued -- not nearly the level of noise and anger you see at sone rallies here.

Okay, the crowd is moving again. Next stop: the Sorbonne. --Martin Enserink

Amsterdam

We all scream for ice cream, and science

Throughout the day, an estimated 2000 people have come to the Museum Square in Amsterdam for this city’s March for Science event. In front of the Rijks Museum, the largest museum on Dutch heritage in the country and holder of some of the most well-known pieces of art in the world, like the Night Watch from Rembrandt, a nice science fair took place. Many activities were inside two white tents, not a bad choice given it was fairly cold and rainy today. The tent run by the Royal Netherlands Academy of Arts and Sciences was popular although that may be because it offered free ice cream. Small exhibits with experiments were everywhere, mainly done by volunteers from different Dutch universities and other science institutes. You could enjoy watching what happens when a marshmallow sits in a vacuum, or just look through a telescope. Scientists in front of research posters explained scientific concepts, like climate change and fabrication of the flu vaccine. One protester’s sign quipped “Science: running everything since 1543,” a reference to Nicolaus Copernicus’ treatise that year arguing our planet revolves around the sun, instead of the other way. --Krijn Soeteman

PARIS

“I’m marching for her”

We're marching past the National Museum for Natural History now, one of many science landmarks along the way. Nélima Heuzé and Antoine Chaillet (below) are marching clad in lab coats, along with their daughter, who's taking pictures. Chaillot says he's troubled by the rise in fake news and uncritical thinking, even among his own relatives. Heuzé, who has test tubes attached to her hat, points at her daughter and says: "I'm marching for her."  --Martin Enserink

BERLIN

Ending with an ode to freedom of thought

The Berlin march has ended with the crowd singing, in harmony, “Die Gedanken sind frei” a German folk song that was prohibited during the student unrest of the 1840s, and again during the Third Reich. It is one of Germany’s most beloved protest songs. --Gretchen Vogel

Barcelona

Beachside science discussion in Barcelona

About 40 volunteers organized this city’s March for Science event, a roundtable discussion not far from one of its famous urban beaches.  Pablo Rodríguez Ros of the Institute of Marine sciences, one among the hundreds of attendee, says he gave up a Saturday “because I think science should be closer to society. We need to involve people to improve the wellbeing of society. We help you, but we need society's help too.”

The event began with a reading of a pro-science manifesto in three languages: English, Spanish, and Catalan. One part declared: “It is worrying the rising acceptance of environmental and safety policies that purposefully go against scientific evidences such as the effectiveness of vaccination, the theory of evolution or climate change.”

The roundtable included scientists, journalists and science policy officials. “We need to march for open science, not just science,” said Joan Subirats a political scientist at the Autonomous University of Barcelona. Another panelist, Mara Dierssen, a neurobiologist at the Centre of Genomic Research, argued that “countries that invest a lot in science have a higher level of life quality and stronger economies. “ Pere Estupinyà, a  journalist participating in the roundtable, also noted “Science is not easy, because sometimes it tells us things we don't want to hear. We can't cherry pick only the things we like!” --Luca Tancredi Barone

BERLIN

10,000 marchers? “That would be an unverified fact.”

Science’s Gretchen Vogel reports from the speeches:

Berlin mayor Michael Müller tells the crowd that while Berlin has a history of great science, it also has a dark chapter when science and scientists were persecuted and silenced. Therefore we especially stand with scientists around the world who suffer political persecution, he says. There is a big cheer for solidarity with Central European University in Budapest, which the Hungarian government has targeted for closure.

Speakers have had to ask the crowd to squeeze forward more so everyone could fit in the allotted space, which is Paritzer Platz, in front of the Brandenburg gate. One speaker, science journalist Ranga Yogeshwar, says there is a rumor that the police estimate 10,000 marchers, "but I want to be careful. That would be an unverified fact."

PARIS

“Marty, science is in danger!”

A sign referencing the film Back to the Future is among those being held by marchers in a crowd of at least a thousand people that has gathered outside the Jardin des Plantes in Paris. Trade unions out in force, it seems. Speeches denouncing Donald Trump and attacks in science and education are in progress; the actual march will start later. --Martin Enserink

BERLIN

Berlin hits the road

In Berlin, marchers gathered at Humboldt University, across from bebelplatz, where Nazis burned books. They marched past the Hungarian embassy, where some marchers held signs in support of the central European university. They have now reached the Brandenburg gate. Organizers just said the crowd is between 4 and 5000 people. --Gretchen Vogel

Bonn

Protests abound in Germany, not all science-related

About 500 people have gathered in drizzly rain in Bonn for a science march with no marching but plenty of signs and several speeches. Many people here said they had a hard time deciding which protest to join this weekend. Several large pro-European Union demonstrations are scheduled for Sunday. And plenty of protests are planned in nearby Cologne where right-wing party Alternative für Deutschland (AfD) is holding a convention this weekend. The party's manifesto has this to say on climate change: "For as long as the earth exists, the climate will change. Policies of climate protection rely on useless computer models of the IPCC. Carbon dioxide is not a harmful substance, but an essential part of life."

Several people here said they knew friends and colleagues who had decided to join those protests to take a stand for science. Other protestors decided to join the March for Science, still somewhat stunned at how the world had changed in recent months. "I really still can't believe we have to fight for facts," says Stephanie La Hoz Theuer, a Brazilian expert on international climate policies who lives in Bonn. "But here we are. You can't take progress for granted." --Kai Kupferschmidt

LONDON

London march revving up

The March for Science London is about to set off from outside the Science Museum. From there marchers will go along the side of Hyde Park, along Picadilly, Pall Mall, Trafalgar Square and then down Whitehall to Parliament Square. A rally there is due to start at 2 p.m. There is a genial atmosphere and numbers are in the thousands.

PARIS

In Paris, a marchsandwiched between a terror attack and presidential elections

The March forScience in Paris will start in less than an hour at the Jardin des Plantes, abotanical garden, from where it will make its way past a series of researchlandmarks on the Left Bank, to finish at the Place St. Michel. It’s one of twodozen events today in France and its overseas territories.

The French marchoften to express their political views, and scientists are no exception; labcoats have flooded the streets and squares of Paris and other cities many timesthe past decade to protest lagging funding, a lack of permanent jobs , orproposed reforms to the academic system. The organizers of today’s march say ina statement that the event is partly about Donald Trump’s “hostile ideology”with respect to science, but also about threats in France, includingpoliticians’ focus on “innovation and the knowledge economy.”

How many peopleshow up today is anyone’s guess. It’s an extraordinary time in France, andParis is on edge. Tomorrow is the first round of what could be the most consequentialpresidential electon in half a century; right-wing nationalist Marine Le Pen ofthe National Front, abhorred by most French academics, is expected to proceedto the 7 May run-off easily. (Here’s a Science news story about the race.) Andthis past Thursday, a gunman attacked a police bus on the Champs Elysées, afamous shopping boulevard here, killing a policeman. (The shooter, aradicalized Frenchman with a violent and criminal past, was also killed.)Several of the main presidential candidates canceled their campaign appearancesyesterday.

The French, inother words, have many other things to worry about besides the future ofscience, which could put a damper on today’s event. On the other hand, it couldalso motivate people to come out and express their trust in science and reason.It will be interesting to what extent the presidential race -- in which sciencehas been notably absent—plays a role in the march. --Martin Enserink

SEOUL

Robots help Korean science community engage the public

The March for Science in Seoul has turned its event into something of a science fair. A variety of science-related groups set up about 15 booths to disseminate information and attract children with biology and robotics demonstrations.

"We were trying to share science with the public," says Seungwhan Kim, a physicist at Pohang University of Science and Technology who chairs the local organizing committee. And the weather cooperated. "It's a beautiful Saturday, sunny and with clear skies; a lot of families were coming to the area," says Kim. The booths, located in a plaza in front of the Sejong Center for the Performing Arts in central Seoul, were open from 11 a.m. until 5 p.m. and attracted "a steady stream of people," Kim says.

An hour of speeches began at 2 p.m. local time, with 10 researchers and teachers describing their lives as scientists to an audience sprawling over the steps of the center. And at 3 p.m., there finally was a march, with about 1000 participants, proceeding through the city's Gwanghwamun district and returning to the center.

Two foreign scientists were among the 10 speakers—one from Syria, the other from the U.S. There were also quite a few non-Koreans participating in the march. "It was an international event," he says. --Dennis Normile

AUCKLAND, NEW ZEALAND

Marchers credit science for humanity's advances

Waving banners reading from "Wasting Science is Wasting Solutions" to "Your Truth Needs Proof," an enthusiastic crowd of 300 to 400 people joined the March for Science in Auckland, New Zealand, this afternoon. Onlookers were captivated as the procession—made up of researchers, families and other science supporters—advanced up Auckland's Queen Street in the heart of the city.

The March for Science NZ organizers say they walked today for “science and knowledge to be reaffirmed as fundamental" to democratic decision-making in New Zealand, as well as to stand in solidarity with fellow scientists worldwide. March co-organizer Steph Borrelle, a conservation scientist at the Auckland University of Technology, told Science that she was also personally motivated to march as a woman in science, technology, engineering, and math (STEM). “I march to demand equity,” she said, "I march for all women who follow after us, so that they can flourish and make science better for everyone.”

Auckland’s march is the last of five taking place in New Zealand today, joining Christchurch, Dunedin, Palmerston North and Wellington. Following the march, the crowd gathered around the bandstand in Albert Park to hear a number of speakers.Microbiologist Siouxsie Wiles, of the University of Auckland, began by stressing the importance of science to modern life. "Science is the reason that I—as a woman—am here today and didn't die 10 years ago when I was giving birth to my daughter," she said. "Science is why many of us didn't die before we got to the age of 5—how amazing is that?" Wiles also said that the scientists were standing with their colleagues in the humanities, who "are also taking a pounding from the government."

"When politicians use their belief systems to override the facts, the scientific facts, we are all in for a whole world of hurt," said Green Party co-leader James Shaw, thanking the crowd for standing with science. In New Zealand, "things aren't nearly as bad as they are in the United States in terms of that political discourse - but it could go that way,” he said. “We do need to stand up against that."

Shaw also stressed the importance of ensuring that science is properly funded in New Zealand. "You [scientists] are heroes, you save lives, you make the future better for all of us," he concluded. "Science is, and always will be, the reason that humanity moves forward," added Alexia Hilbertidou, founder and CEO of the NZ-based organization GirlBoss, which encourages young women to enter male-dominated STEM fields. She concluded: "We must be a generation brave enough to stand on the shoulders of science and see further - and then march forward into that future." --Ian Randall

SYDNEY

Marchers spill into streets surrounding park

The event in Sydney started at noon local time with a lineup of speakers who found themselves addressing a crowd that filled Martin Place, a pedestrian mall stretching for several blocks in the central business district. "We're absolutely packed, the crowd is massive, well beyond expectations," says Stuart Khan, an environmental engineer at the University of New South Wales in Sydney, told Science by phone. "People are overflowing onto the road," he adds. Speeches are wrapping up at 1 p.m. and then participants will march down Macquarie Street, past the building housing the New South Wales parliament, to Hyde Park, at the very center of Sydney.

The Sydney crowd probably numbers over 2000, says Jocelyn Prasad, media coordinator for the Australian marches. "We've got a wide variety of ages and groups, it's peaceful, and there is a great feeling of solidarity," she adds. "We're feeling pretty happy about it just now."

They don't yet have turnout numbers for the other 8 marches happening around Australia at different times today. But the other events also seem to be going well. "We're happy to be kicking it off globally, we're hoping they get a good turnout in the States," Prasad says. --Dennis Normile

TOKYO

Small but enthusiastic crowd marching through downtown Tokyo

The numbers for the march in Tokyo are modest at just 50 to60, as a result of a late start on organizing. "It's not a huge number,but we are all quite excited, certainly," says Rintaro Mori, a healthpolicy expert at Japan’s National Center for Child Health and Development inTokyo. Starting at 11 a.m. local time, marchers were heading out from HibiyaPark, which is located in the heart of the capital's governmental ministrydistrict, and walk through the streets to Tokyo Station. "People from thegovernmental sector will be able to see us quite well," Mori says.

In addition to the typical signs pronouncing "Sciencenot Silence" and "Respect Science," Mori says several people arecarrying banners focusing on particular concerns, including the environment andrenewable energy. One marcher in Christian religious garb is carrying aJapanese language sign that reads: "Religious people respectscience."
