Hello Nature readers, Today we hear a call for the global community to stand united in defence of science in the United States, learn how animals sculpt the surface of Earth and explore how AI might help researcher remedy poverty. You might have noticed that some Nature stories now require you to register your e-mail address to read all the way to the end.

Nature denounces Trump’s assault on science

US president Donald Trump has turned his back on the opportunity to build on the nation’s legacy and achievements in science, argues a Nature editorial. “It is hard to put into words the extent of the damage being done to the US research enterprise, which is of almost incalculable value to both the nation itself and the wider world.” Those working at federal agencies might feel unable to speak up, so others across the globe — such as those at universities, scientific societies, businesses, labour unions and campaign groups — must do so. “The US scientific and educational communities must know that they are not alone,” says the editorial. “An assault on science and scientists anywhere is an assault on science and scientists everywhere.” Nature | 7 min read

Over thousands of years, tunnel-digging termites (Syntermes dirus) in Brazil have excavated more than10 cubic kilometers of soil — equivalent to 4,000 great pyramids of Giza — in mounds visible from space. (Victor R. Caivano/AP Photo via Alamy)

How animals shape Earth’s surface

The first global study of how animals push, pull, dig, scratch and otherwise alter the landscape reveals the enormity of their influence. From beavers creating wetlands to salmon reshaping riverbeds, animals contribute at least 76,000 gigajoules of energy annually to shaping Earth’s surface — a figure that researchers equate to hundreds of thousands of extreme floods. But nearly 30% of the Earth-architect species identified by this study are rare, endemic, or threatened — and losing them could also mean the loss of important geomorphic processes.

US pulls back from from key climate panel

Trump’s administration has blocked NASA chief scientist Katherine Calvin and other US officials from participating in a meeting in China this week about a major United Nations climate assessment. The planning meeting is slated to end with the adoption of an outline for the Intergovernmental Panel on Climate Change’s seventh climate assessment. These assessments are used by governments worldwide to shape their climate policies. NASA has also cancelled a contract that funded a team to provide administrative and technical support to the climate-assessment effort, according to a US official. Nature | 5 min read

Can AI help to end poverty?

Quashing poverty requires knowing who is in need and what their needs are, but collecting those data has long been a time-consuming and costly challenge. Some researchers are turning to artificial intelligence (AI) tools to help plug the gaps. AI can be biased, and could miss people without a digital trail. On the other hand, it can analyse a larger, more representative portion of the population than do household surveys, and identify patterns in data that even specialists could miss, says development economist Ariel BenYishay.

Reward behaviours that benefit academia

Most academics agree that the measure of a great researcher should be more than the number of well-cited papers they’ve published in high-impact journals, says educational psychologist Kelly-Ann Allen. Yet publication-based evaluation metrics continue to thrive. Allen proposes an alternative metric, the ‘G+ index’ — G representing the ‘good things’ in academia — that rewards behaviours such as mentorship, collaboration and ethical science practices. “The community faces a choice: maintain the status quo, or experiment with new measures that better align with our values,” Allen writes.

How to protect the gut from antibiotics

Antibiotics save lives, but they also wreak havoc on the beneficial bacteria that inhabit the human gut. Researchers are pursuing several strategies to protect these helpful microbes. One company has genetically engineered bacteria and nutritional yeast to carry an enzyme that breaks down amoxicillin in the gut without affecting the antibiotic’s ability to fight infection elsewhere in the body. Other scientists have found that high- fibre diets allay antibiotics’ effects on the gut by changing how intestinal microbes metabolize nutrients.

Image of the week

Anna Ortega tracks deer in Wyoming as part of her consulting work analysing wildlife data for academic laboratories, state and federal agencies and conservation non-profit organizations. She is among the PhD scientists who forged a career off the beaten track, far from a research hub or a university town. “I advise PhDs with extreme geographical restrictions to think broadly and widely about what they can do,” says career coach Karen Kelsky, who founded her business after leaving a tenured academic position for family reasons. “It is becoming more normative to not work in academia.” (Nature | 12 min read) (Benjamin Kraushaar)

Quote of the day

“I started to realize that I wasn’t a scientist tinkering in a lab… I was, in fact, a health-care professional and I could see the names of the people we were providing these faulty results for.” As a lab assistant straight out of university, Erika Cheung got a job at the blood-testing company Theranos. She ended up blowing the whistle on problems at the high-profile start-up, and the choice changed the course of her life. (Nature | 10 min read)

Today I’m enjoying this beautiful visual exploration of the challenges of using Pinyin romanization for Chinese names by data-visualization specialist Liuhuaying Yang. The work reveals how transliteration can create ambiguity, as thousands of distinct Chinese characters are compressed into just 375 syllables. In some cases, people with different Chinese names end up with the same Pinyin name. “When studying author relations or gender inequality in academia… Chinese names are often excluded from research due to these challenges,” notes Yang. While I boot-up my Chinese-language app and get practicing, why not send me your feedback on this newsletter? Your e-mails are always welcome at briefing@nature.com.
