| Nocturnal insects aren't attracted to artificial lights because they confuse them with the Moon. (Sam Fabian) | |||||
What draws the moth to the flameNocturnal insects appear drawn to artificial lights because they instinctively twist their backs towards bright objects. The instinct to tilt their backs towards the brightest thing available at night — the sky — allows insects to quickly figure out which way is up. Researchers who tracked insects' flight patterns with motion-capture cameras found that this even leads the animals to flip upside down and crash into the ground when the light source is underneath them. The researchers suggest reducing upward-facing lights and ground reflections to avoid confusing flying insects at night. Nature | 7 min videoReference: Nature Communications paper | |||||
How to make academic hiring fairA new online resource shows off the best of research-assessment and career-development policies. The Reformscape database, launched by the Declaration on Research Assessment (DORA), aims to show university administrators practical, actionable ways to improve their own policies. "It can be difficult to convince people from a standing start that change is possible," says DORA's programme director Zen Faulkes. "This is a tool to help them get unstuck."

Trump's presidential push worries scientistsDonald Trump has promised to limit the authority of federal agencies and employees, including scientists, if he wins in the upcoming US elections. His plan, known as Schedule F, would allow the government to more easily fire federal employees and appoint politically-aligned replacements regardless of their scientific expertise. If the plan gets the green light, "you would have nobody to report scientific-integrity violations, because anybody who objected would be fired", says Betsy Southerland, a former environmental scientist at the US Environmental Protection Agency.

Tinkling the ivories boosts your brainPlaying a musical instrument is associated with a sharper mind later in life. And the instrument matters: in a study of people over 40 in the United Kingdom, "keyboard and, to a lesser extent, brass instrument play was strongly associated with better working memory, with executive function favoured in woodwind players". "Our brain is a muscle like anything else and it needs to be exercised," says dementia researcher and co-author Anne Corbett.

The emerging field of cancer neuroscienceResearchers are parsing the many ways in which cancer co-opts the nervous system for its own benefit — even outside the brain. In much the same way as tumours recruit blood vessels to feed themselves and grow, cancer relies on the nervous system for everything from initiation to spread. These initial discoveries are already pointing to potential cancer treatments, using therapies already known to be safe. Beta blockers, for instance, can disrupt signals from sympathetic nerves that drive cancer progression in the breast, pancreas, prostate and elsewhere. Nature | 11 min read | |||||

How to prevent pandemic vaccine hoardingAn international treaty to prepare for future pandemics could offer the opportunity to ensure that life-saving vaccines and treatments are available to all who need them, argues a Nature editorial. To make it happen, public funders could agree that their money comes with strings: they could, for example, require grantees to openly share study results. They could also require that products arising from those studies be priced affordably and retain certain intellectual property to facilitate access in low- and middle-income countries.

| DNA sequences captured from microbial samples — which were gathered from microbes in the wild and across different habitats, and include species that have not been cultivated in the laboratory — have revealed hundreds of thousands of previously unknown gene families. "By delving deeper into the microbial dark matter, these two studies unlock a wealth of previously hidden knowledge, paving the way for future discoveries in diverse fields from medicine to biotechnology," write biomedical researchers Jakob Wirbel and Ami Bhatt.

Quote of the day"There were people that published in journals that no serious mathematician reads, whose work was cited by articles that no serious mathematicians would read, coming from institutions that nobody knows in mathematics."The entire field of maths has been excluded from Clarivate's highly-cited-author rankings following a damning analysis by mathematician Domingo Docampo.

What matters in science | View this email in your browser Friday 10 November 2023 Hello Nature readers, Today we learn that the hottest year on record has exposed one-quarter of people to dangerous levels of extreme heat. Plus, UK scientists are reeling over the intervention of a government minister and how to tame a toxic antifungal drug. Among 700 big cities, Houston, Texas experienced the longest climate-change influenced heat wave: 22 days. (Brandon Bell/Getty) Ear...
