Why babies forget, and how fear lingers in the brain
Investigating “infantile amnesia,” and how generalized fear after acute stress reflects changes in the brain This week we have two neuroscience stories. First up, freelance science journalist Sara Reardon looks at why infants’ memories fade. She joins host Sarah Crespi to discuss ongoing experiments that aim to determine when the forgetting stops and why it happens in the first place. Next on the show, Hui-Quan Li, a senior scientist at Neurocrine Biosciences, talks with Sarah about how the brain encodes generalized fear, a symptom of some anxiety disorders such as social anxiety and post-traumatic stress disorder....

Early nasal intermittent positive pressure ventilation (NIPPV) versus early nasal continuous positive airway pressure (NCPAP) for preterm infants
About one in ten live births around the world are preterm and many very preterm babies will develop respiratory distress soon after birth and require help with their breathing. Various strategies are available for this and an updated Cochrane review from July 2023 provides the latest evidence on the early use of nasal intermittent positive pressure ventilation compared with nasal continuous positive airway pressure. We asked one of the authors, Marc-Olivier Deguise from the Children ' s Hospital of Eastern Ontario in Canada to tell us about the findings, and he used ElevenLabs to make this recording.

Nasal intermittent positive pressure ventilation (NIPPV) versus nasal continuous positive airway pressure (NCPAP) for preterm neonates after extubation
About one in ten live births around the world are preterm and many of these babies will develop respiratory distress and require help with their breathing. Various strategies are available for this and an updated Cochrane review from July 2023 provides the latest evidence on the comparison of nasal intermittent positive pressure ventilation versus nasal continuous positive airway pressure when a baby ’s breathing tube is removed. We asked one of the authors, Marc-Olivier Deguise from the Children ' s Hospital of Eastern Ontario in Canada to tell us about the findings, and he used ElevenLabs to make this recording. (Sourc...

What are the risks and benefits of different positions for spinal taps in infants?
The Cochrane Neonatal Group works on producing and updating Cochrane Reviews to provide comprehensive data based on the latest evidence about the care of babies and infants. In December 2023, they added to their more than 450 reviews with one on the position used to perform spinal taps. Here are two co-authors of the review, Marcus Glenton Prescott from St. Olav ’s Hospital, Trondheim in Norway and Sara Pessano from Gaslini Children ' s Hospital in Genoa Italy, to tell us about the findings.

What are the benefits and risks of methylxanthines (mild stimulant medicines) for premature babies whose breathing pauses during sleep (apnea)?
An important problem for babies who are born too early is a condition called apnea and a new Cochrane review published in October 2023 brings together the evidence on the effects of a class of drugs called methylxanthines. We asked one of the authors, Matteo Bruschettini from Cochrane Sweden, to tell us about the review ' s findings in this podcast and he used an AI voice from elevenlabs.io to make the recording.

Even a 'minimal cell' can grow stronger, thanks to evolution
In this episode:00:46 The effects of evolution on a minimal genomeIn 2016, researchers created a ‘minimal cell’ bacterium with a genome that only contains genes essential for the organism's survival. Any mutation in these genes could be fatal, so it was unclear whether there could be scope for evolution. But now, a team has grown this bacterium through 2,000 generations and shown that it does have the ability to evolve and can recover from some of the fitness costs associated with its streamlined genome.Research article: Moger-Reischer et al.09:21 Research HighlightsDolphins use ‘baby talk’ when talking to their of...

Does the placement of a breathing tube using video assistance (videolaryngoscopy) increase the success and safety of the procedure in newborn babies?
As you can imagine, placing a breathing tube into a newborn baby is a particularly challenging task, and research has been done into different ways to do this. In May 2023, Mohan Pammi and co-reviewers from Baylor College of Medicine, Children ' s Hospital of Philadelphia and Boston Children ' s Hospital, updated the Cochrane review on comparing videolaryngoscopy to the traditional direct laryngoscopy approach and Mohan describes the latest findings in this podcast.

Building big dream machines, and self-organizing landscapes
Builders of the largest scientific instruments, and how cracks can add resilience to an ecosystem
First up this week, a story on a builder of the biggest machines. Producer Kevin McLean talks with Staff Writer Adrian Cho about Adrian’s dad and his other baby: an x-ray synchrotron.
Next up on this episode, a look at self-organizing landscapes. Host Sarah Crespi and Chi Xu, a professor of ecology at Nanjing University, talk about a Science Advances paper on how resilience in an ecosystem can come from the interaction of a plant and cracks in the soil.

Bacterial ‘syringes’ could inject drugs directly into human cells
00:48 Tiny syringes for drug deliveryA team of researchers have repurposed tiny syringe-like structures produced by some bacteria to deliver molecules directly into human cells. They hope that this method could be used to overcome a big challenge in modern medicine, namely ensuring that therapeutics are delivered into the precise cells that need to be treated.Research article: Kreitz et al.News and Views: Mix-and-match tools for protein injection into cells07:05 Research HighlightsA diamond-like material could protect spacecraft from intense radiation, and how gene editing could help in the treatment of a rare genetic cond...

Talk Evidence - masks, chronic pain, and baby milk formulae claims
In this episode of Talk Evidence, Helen Macdonald is joined by Juan Franco and Joe Ross, to bring you the newest evidence in The BMJ.
First, chronic pain. As prescribers move away from opioids, Juan finds an overview of systematic reviews asking whether anti-depressants might help.
Joe finds new research on the link between six healthy lifestyle markers and cognitive decline.
Helen looks at a trial to reduce prescribing among older people with suspected urinary tract infection or UTI.
Juan has a nuanced take on the updated evidence on masks to reduce the spread of respiratory viruses.
Finally, an international grou...
