How a key Alzheimer's gene wreaks havoc in the brain

00:46 Artemis 1 is go!NASA’s Artemis 1 mission has successfully reached Earth orbit. After weeks of delays and issues, and a nail biting launch, the rocket marks the first step in a new era of moon exploration, with plans to test a new way to return astronauts to the moon. We caught up with reporter for all-things-space, Alex Witze, for the latest.News: Lift off!

Whilst the biggest risk factor of late-onset Alzheimer’s is age, there are a number of genes that have been implicated. How exactly these genes underpin this disease is unclear, but new research may now reveal how one of them does so, by affecting the myelination of neurons. The authors hope this work may help uncover treatments for Alzheimer’s.Research Article: Blanchard et al.News and Views: Alzheimer’s risk variant APOE4 linked to myelin-assembly malfunction20:44 Updates from COP27The second week of the 27th UN Climate Change Conference is underway, as policymakers and scientists try to come together to tackle climate change.

Molecular cages sift 'heavy' water from near-identical H2O

00:49 Separating heavy water with molecular cagesHeavy water is molecule very similar to H2O but with deuterium isotopes in the place of hydrogen atoms. Heavy water is useful in nuclear reactions, drug design and nutritional studies, but it's difficult to separate from normal water because they have such similar properties. Now, a team have developed a new separation method using tiny molecular cages, which they hope opens up more energy efficient ways to produce heavy water.Research article: Su et al.News and Views: A molecular flip-flop for separating heavy water07:23 Research HighlightsHow dancers can feel the beat even when they can’t hear it, and how climate change might move desert dunes.Research Highlight: Dancers pick up the pace on a bass beat — even though it’s inaudibleResearch Highlight: Desert dunes pose more danger as Earth warms09:25 Monitoring bridge health using crowd dataBridges are vital pieces of infrastructure but their structural health is hard to monitor, requiring either sophisticated sensors or intense surveying by human engineers. Now though, researchers have utilized large amounts of smartphone accelerometer data to check the health of the Golden Gate Bridge. They hope this new technique can be used to effectively and cheaply monitor bridges around the world.Research Article: Matarazzo et al.Communications Engineering special issue: Resilient Infrastructure17:00 COP27 gets underwayThis week the 27th UN Climate Change Conference began, with world leaders, scientists and activists coming together to continue negotiations aimed at reining in global warming.

Flies can move their rigid, omnidirectional eyes – a little

00:46 How flies can move their eyes (a little)It's long been assumed flies’ eyes don’t move, and so to alter their gaze they need to move their heads. Now, researchers have shown that this isn’t quite true and that fruit flies can actually move their retinas using a specific set of muscles, which may allow them to perceive depth. The team also hope that this movement may provide a window into some of the flies’ internal processes.Research article: Fenk et al.08:54 Research HighlightsHow the 80-year-old wreck of a sunken warship is influencing ocean microbes, and tracing an epilepsy-related gene variant back to a single person from 800 years ago.Research Highlight: A ship sunk during the Second World War still stirs up the seabedResearch Highlight: Families on three continents inherited their epilepsy from a single person11:11 Calls to mandate militaries’ emissions reportingThe eyes of the world will be focused on the UN’s upcoming COP27 conference to see what governments will pledge to do to reduce global emissions. But there’s one sector of countries’ carbon outputs that remains something of a mystery: the emissions of their militaries. We speak to Oliver Belcher, one of a group of researchers who have written a Comment article for Nature, calling for better reporting and greater accountability for these military emissions.Comment: Decarbonize the military — mandate emissions reporting19:07 Briefing ChatWe discuss some highlights from the Nature Briefing.
