- Seven feel-good science stories to restore your faith in 2025 www.nature.com/articles/d41...
- As 2025 ends, I reflect on a year of growth & professional opportunities, including the @frontiersmedia.bsky.social residency at @istaresearch.bsky.social, which let me step back from headlines & focus on the science that inspires me. Along the way, I wrote many stories—these are my favorites🧵
- 🧠 For @thetransmitter.bsky.social, I reported on new research suggesting autism may not be a single continuous spectrum, but a collection of distinct subtypes, each with its own genetic signature: www.thetransmitter.org/spectrum/fou...
- 🔥 For @nature.com, I covered Europe’s record-breaking summer of 2025, as extreme heatwaves drove heat-related deaths, wildfires, and unprecedented strain on power systems: www.nature.com/articles/d41...

- Had a great time at @sidb-edinburgh.bsky.social last week, giving a seminar on how researchers can engage with the media — from interview prep to dos & don’ts. Great questions, great energy — shows the appetite for connecting science & society.
- In my latest for @nature.com, I explain how this year’s back-to-back heatwaves are affecting populations and economies across Europe. www.nature.com/articles/d41...
- Wrapping up my @erc.europa.eu funded @frontiersmedia.bsky.social Fellowship at @istaresearch.bsky.social. In 4.5 months, I gave talks on science journalism, visited Austrian newsrooms and connected with researchers and journalists worldwide. Grateful for the opportunity and excited for what’s next!
- Read my latest for @thetransmitter.bsky.social: A large study links patterns of traits in autistic children to distinct genetic signatures, challenging the idea of a single autism spectrum and paving the way for more personalized care and support. www.thetransmitter.org/spectrum/fou...
- Spoke at @viennabiocenter.bsky.social last week about my path from lab bench to newsroom. I talked science journalism (what it is + isn’t), how to talk to journalists, and how to start in #scicomm. Thanks to @irmaquerques.bsky.social & @vbcscitraining.bsky.social for having me!
- Had a blast talking at @istaresearch.bsky.social’s Think & Drink last Friday! @clarewatson.bsky.social and I shared how we went from lab bench to newsroom, and why trust, curiosity & scientist voices matter in journalism. Thanks to all who joined!
- I helped @nature.com put together a guide to the initiatives drawing U.S. scientists abroad as the Trump administration cuts research budgets and science agencies. The trend has sparked debate: Is luring talent away the best way to support global science? www.nature.com/articles/d41...
- Thank you to the organizers, fellow panelists, and audience for a fantastic panel on science journalism—insightful questions and a thoughtful discussion!
- Panel discussion at ISTA: Renowned science journalists discussed both the challenges and the joys of science journalism. Thanks to our panelists: @clarewatson.bsky.social, @giorgiag-sciwriter.bsky.social, @jackiesnow.bsky.social, Monika Mondal, Klaus Taschwer & moderator Marlene Nowotny!
- For @nature.com, I spoke with US-based researchers who are pursuing or relocating to jobs overseas in response to actions taken by the Trump administration, which has started to dismantle US research agencies and attempted to exert greater control over universities. www.nature.com/articles/d41...
- Tomorrow I’m joining four amazing colleagues from around the globe to talk about science journalism — how it can offer clarity, hope, and accountability in uncertain times. Don’t miss it! More info at: ista.ac.at/en/news-even...
- Reposted by Giorgia Guglielmi (she/her)Meet our Journalists in Residence 2025! Four independent science journalists from around the globe stay at the ISTA Campus for several months, unearthing stories about science and research that have never been told. 🧵A thread about them and their fields of expertise:
- Read my latest neuroscience story: REM sleep preserves newly acquired memories, but deeper non-REM sleep helps to adapt and update them, preparing the brain for future experiences, according to “heroic” day-long electrode recordings in rats done at @istaresearch.bsky.social 🧠 #FRONTIERSfellow
- A new study shows how sleep helps the brain process the past and prepares it for future experiences, with REM and non-REM sleep reshaping memories in opposite ways. By @giorgiag-sciwriter.bsky.social www.thetransmitter.org/sleep/sleep-...
- Reposted by Giorgia Guglielmi (she/her)Submit your nominations for our 2025 "Rising stars in neuroscience." Don’t miss the opportunity to recognize your colleagues who have made outstanding scientific contributions and demonstrated a commitment to community-building. Enter here: www.thetransmitter.org/the-transmit... #neuroskyence
- As a @frontiersmedia.bsky.social Fellow, I’m excited to explore a fascinating question at @istaresearch.bsky.social: How do living systems—from embryos to animal colonies—self-organize? At ISTA, I’ll engage with researchers studying this phenomenon from various angles. #FRONTIERSFellow
- Reposted by Giorgia Guglielmi (she/her)A new statistical method controlling for hidden confounders could help pinpoint true causal links in neurodevelopmental conditions such as autism. By @giorgiag-sciwriter.bsky.social www.thetransmitter.org/spectrum/new...
- Had an amazing time at the @frontiersmedia.bsky.social training at @itqbnova.bsky.social! It was fantastic meeting other FRONTIERS fellows and discussing a wide range of topics—from reporting about frontier research to the role of AI in science journalism.
- My latest for @nature.com: Breast cancer is the most common cancer in women worldwide, but survival chances vary drastically depending on where a woman lives, a new study shows. www.nature.com/articles/d41...
- Reposted by Giorgia Guglielmi (she/her)Neurons primarily rely on glucose—rather than lactate from astrocytes—to generate energy, according to recent findings in mice. By @giorgiag-sciwriter.bsky.social www.thetransmitter.org/metabolism/f...
- My latest for @nature.com: Drug companies are trialling a host of medications that they hope will offer benefits beyond weight loss. I took a look at the weight-loss medicines being tested in 2025 and what they have to offer.

- Read my latest for @nature.com: An analysis of data from nearly 2 million people reveals new insights into the benefits and risks of blockbuster obesity drugs like Ozempic, which are praised for treating weight loss and various other conditions.
- My latest for @nature.com: Fresh approach to diagnosing obesity focuses on how excess body fat affects the body, rather than relying only on body mass index (BMI), which links a person’s weight to their height.
- As 2024 comes to a close, I look back at the inspiring stories that I had the chance to explore this year—from intact mammoth chromosomes to new hope for childhood cancer treatments. I’ve rounded up my five favorite pieces for you in this thread 👇
- Researchers found that the ratio of specific microbial communities in the gut can help to predict who will respond to next-generation drugs for treating some kinds of cancer www.nature.com/articles/d41...
- In samples of a 50,000-year-old woolly mammoth’s skin, researchers discovered chromosomes preserved in their original 3D configuration—a feat previously thought impossible in ancient-DNA research www.nature.com/articles/d41...
