Cloning scientist gets 12-year prison sentence
A Chinese court has sentenced leading animal-cloning researcher Li Ning to 12 years in prison for embezzling millions in research funding. Li was one of several scientists at Chinese universities who were arrested in 2014 for misusing research grants. Li has denied stealing the money, and said that he had invested unused grant funding with the intention of supporting research in future years.
Meteor contains oldest material on Earth
Some grains of interstellar dust in a meteorite that fell to Earth in 1969 are almost 3 billion years older than our Sun. The specks of dust were incorporated in the meteorite after they were flung out from dying stars between 4.6 billion and 7.5 billion years ago. “They’re solid samples of stars, real stardust,” says cosmochemist Philipp Heck.
Researchers dated the dust on the basis of neon isotopes produced from exposure to galactic cosmic rays while in space. The age distribution of the dust offers evidence that there was a star formation boom in our Galaxy 7 billion years ago.
Predatory-journal papers make no impact
Papers published in ‘predatory’ journals are cited much less often than those in reputable publications. An analysis of 250 articles concludes that papers in predatory journals have “very limited readership among academics”, and therefore have little effect on science.

US regulators let trials dodge the rules
Many prestigious US universities, companies and institutions that conduct clinical trials continue to break the law by failing to make the results public. Science looked at more than 4,700 trials that should have been registered on ClinicalTrials.gov and found that trial sponsors violated the reporting law more than 55% of the time. Science names and shames 30 offenders and points the finger at the National Institutes of Health (NIH) and the Food and Drug Administration (FDA) for failing to apply sanctions. The FDA hasn’t collected a dollar in penalties (analysts estimate it could have claimed US$6 billion) and the NIH has yet to withhold a single grant.
PhD and carer: how I got through it
“Caring for a loved one who had cystic fibrosis and was waiting for a transplant, while I was trying to complete my PhD programme, seemed impossible,” writes clinical researcher Luke Yates. He describes how a compassionate supervisor and a range of techniques helped him to maintain his experiments, his family commitments and his mental health.
Document-sharing tools for scientists
Go beyond Google Docs with these three tools to collaborate on writing. HackMD is a lightweight, browser-based editor for files written in Markdown, with good version control. Manubot is a solution developed by scientists to turn a GitHub repository into a self-published manuscript, including error checking and pulling in figures. And for those who love LaTeX, Overleaf is great at handling references and generating bibliographies.

Big data brings big hopes in health
The digitalization of medical records, increasing affordability of molecular testing, the advent of medical informatics and widespread use of wearables has fuelled an explosion of data related to health care. Nature Medicine explores how it can be wrangled for the benefit of human health.
• Big data is already redefining what means to be ‘healthy’, uncovering unknown disease-risk factors and allowing more-accurate diagnostic and prognostic predictions. Computational biologist Eran Segal and two colleagues take a deep dive into the types of data involved, and the challenges and promises of using it. (36 min read)
• Big data offers to revolutionize social science — and amplify our deepest cultural biases, argues public-health data expert Emily Courey Pryor and five colleagues. They call for big data to be “intentionally managed as a vehicle for equity and empowerment, not simply as a novel technical resource”. (5 min read)
• Big data means big risks when it comes to the security of very personal information. Bioethics legal scholars Glenn Cohen and Nicholson Price explore the concept of health privacy and how to enforce it. (29 min read)
