Hello Nature readers, | ||

| Several donors’ cells were first grown individually before being combined into a single brain ‘organoid’. This stops faster-growing cell lines from smothering slower-growing ones. (N. Antón-Bolaños et al./Nature) | ||
Brain organoid is a ‘village in a dish’
Researchers have grown the first 3D model brains that include an array of cells from multiple people. The donor stem cells are bathed in a chemical cocktail that encourages them to mature into various brain cells. The resulting ‘Chimeroids’ could help to reveal why drugs have distinct effects on different people. Test experiments showed for example that ethanol, the toxin that causes fetal alcohol syndrome, reduced the number of cells from just one donor’s cell line.

DNA donors learn their genetic secrets
The 210,000 Estonians who contributed samples to the country’s biobank — around 20% of the adult population — were given the opportunity to learn about some of their disease risk, Neanderthal ancestry or ability to handle caffeine. So many people flocked to the online portal that parts of it crashed. The project is one of the world’s biggest efforts to return genetic results to research participants — most biobanks do not provide such information. “The hope, anticipation and expectation is that this should improve people’s health care,” says clinical pharmacologist Dan Roden.

A win for US misinformation research
The highest court in the United States has ruled that the country’s government can keep talking to scientists and social-media firms to curb misinformation on subjects such as elections and vaccines. The decision is a win for researchers who continue to face lawsuits alleging that they worked with the government to censor conservative opinions. The court has yet to rule on a related case focused on state regulations that attempt to limit social-media companies’ ability to regulate conversations on their platforms. Nature | 6 min read |
Why the UK election matters for science
Scientists are hoping that the next UK government, which will be elected next week, will return stability after more than a decade of upheaval. One of the most talked-about issues has been the recently-tightened visa rules, which have drastically reduced the number of international applicants to UK universities. Many scientists would also like to see an increase in research funding, which is currently around 2.9% of gross domestic product. Nature | 7 min read |

Work-life balance for male academics
Becoming a father caused organizational-behaviour researcher Dritjon Gruda to recoil from the advice he had received from senior scientists: minimize time with your children and stay steadily focused on research. Instead, he decided to stop working weekends, stick to a 9-to-5 day and keep the laptop closed at home. “Did my career tank? Did I become less successful? Quite the opposite,” he writes. “This is down to, I think, my better work–life balance: I’m more productive in the limited time I devote to work.” Nature | 6 min read |
What makes a world-class lab
The UK Medical Research Council’s Laboratory of Molecular Biology (LMB) produced a dozen Nobel prizewinners and biomedical breakthroughs. “None of these discoveries was serendipitous,” argues a trio of researchers. They interviewed scientists and analysed decades of archival documents to identify some of LMB’s strategies for success:
