How to battle Alzheimers in Africa nature video 2024-09-30 | Researchers are looking to find interventions for Alzheimer's in Africa, a region that's historically overlooked.Research in Alzheimer's is progressing rapidly, opening up more interventions and treatments, but there are concerns that not everywhere in the world will benefit from such advances. In fact, most of the dementia cases in the world are in low- and middle-income countries, a number that will only increase as their populations age. The new research will identify the best interventions to try and prevent the progression of Alzheimer's in Africa and allow better brain ageing for all.Read more about Alzheimer's disease nature.com/collections/adgggicdcaRead the paper: alz-journals.onlinelibrary.wiley.com/doi/10.1002/alz.079009This Nature Video is editorially independent.

Watch this octopus ‘punch’ a freeloading fish 🐙🐙 nature video 2024-09-28 | When looking for their next meal, new footage shows that octopuses collaborate with different species.Researchers were able to observe 13 instances of cross-species group hunting, in which a big blue octopus worked with different fish species to capture prey. Each species was shown to take on a different role. For example, goatfish, especially blue goatfish, were often seen exploring different areas and encouraging the group to follow suit. However, octopuses seemed to help the group decide whether to move or not. Thanks to their eight arms, octopuses were able to suss out hidden prey, and encourage the group to stay in place.The researchers also found that certain fish species, such as blacktip groupers were seen as opportunistic. They would join the hunting group without supporting the group's efforts. When this happened, the octopuses weren’t afraid to tell them off with a quick punchRead the full article at nature.com/articles/d41586-024-03127-5Reporter: Helena Kudiabor
Detecting Alzheimers 20 years before onset nature video 2024-09-27 | Biomarkers for Alzheimer's disease begin to change many years before symptoms present and a diagnosis is made.Shuheng Wang and Bote Zhao worked on a long term study tracking these changes. The team took samples from participants' cerebrospinal fluid, imaged their brain and carried out cognitive assessments over a 20 year period. They found one biomarker (amyloid-beta 42) began to differ, compared to participants who didn't go on to develop the disease, 18 years prior to diagnosis and many others would deviate in the years preceding. It's hoped these findings will lead to early diagnosis and intervention for those with Alzheimer's disease.Read more about Alzheimer's disease nature.com/collections/adgggicdcaRead the paper: nejm.org/doi/10.1056/NEJMoa2310168?url_ver=Z39.88-2003&rfr_id=ori:rid:crossref.org&rfr_dat=cr_pub%20%200pubmedThis Nature Video is editorially independent.

The macabre wasp that lays its eggs *inside* live fruit flies 🪰 nature video 2024-09-21 | Drosophila fruit flies are well studied insects. For over a century, these tiny animals have been at the centre of some of the biggest molecular and genetic breakthroughs in science. But despite being under the microscope all this time, it looks like researchers have missed something. And that something is a minuscule wasp that preys on them.This wasp species, named Syntretus perlmani, was discovered by chance in an infected fruit fly collected in a Mississippi backyard. Only a couple of millimetres long, it lays its eggs inside adult fruit flies. These eggs develop into larvae which grow and feast inside the host before bursting out to continue their lifecycle.Despite being new to science, genomic analysis suggests its widespread across much of the US.youtube.com/watch?v=cvQVh5vnDQw&t=1170s
These black hole jets are HUNDREDS of Milky Way galaxies long 🕳️ nature video 2024-09-18 | Black holes are often thought of in terms of sucking things in, but in some cases they also fling stuff out as well. When this happens matter gets ionized and fired out from the top and bottom of the black holes. These violent and powerful phenomena are known as black hole jets. The biggest of these are made by supermassive black holes and can be up to several million light years in size. And now a team has seen the biggest yet. It’s around 7 megaparsecs, or 23 million light years, in size. To put that another way, if you take the Milky Way as being 100,000 light years across then that's like 233 milky way galaxies stacked on top of each other end to end. That is a full six and a half million light years bigger than the maximum size astronomers theorised these jets to be.youtube.com/watch?v=V2Bx91IG0xA
Should we rename an SI unit after Emmy Noether? nature video 2024-09-07 | The unit of momentum is currently known as kilogram metres per second (kg m/s) according to the International System of Units. However, in a letter to the American Journal of Physics a teacher has started a campaign for it to become know as the noether.Emmy Noether was a mathematician who changed physics with her discovery that symmetries are at the heart of physical laws.
One of Stonehenges megaliths comes from Scotland 🏴 nature video 2024-09-03 | Stonehenge, the Neolithic stone circle on Salisbury Plain in southern England, has captivated archaeologists, antiquarians and sightseers for centuries. For decades researchers have tried to find the origins of the stones, with some being sourced to the surrounding landscape and some from the Preseli Hills in Wales.But new geochemical analysis of the Altar Stone, a partially buried slab of sandstone at the centre of the stone circle, suggests that this stone originally came from the Orcadian Basin in Scotland over 700 kilometres away.Read the full article at nature.com/articles/s41586-024-07652-1
Underwater bridge gives clues to ancient human arrival nature video 2024-08-30 | Mallorca is the largest of the Balearic islands and the sixth-largest island in the Mediterranean Sea, but despite its size and location research suggests that it was among the last Mediterranean islands to be settled by humans. But exactly when people arrived on the island is a subject of much debate, with current estimates placing it at around 4,400 years ago.However, an ancient stone bridge in a flooded cave may call that timeline into question. By dating mineral deposits in the cave scientists have given a new window for when they suggest humans actually reached the island — at least 1,000 years earlier than previously thought.Read the paper: nature.com/articles/s43247-024-01584-4
The future of detecting gravitational waves: A three minute guide nature video 2024-08-21 | Observatories, experiments and techniques are being developed to spot ripples in space-time at frequencies that currently can’t be detected. LIGO and Virgo are laser interferometers: they work by detecting small differences in travel time for lasers fired along perpendicular arms, each a few kilometres long. But physicists are also exploring entirely different techniques to detect gravitational waves. These strategies, which range from watching pulsars to measuring quantum fluctuations, hope to catch a much wider variety of gravitational waves, with frequencies in the megahertz to nanohertz range.Read more at nature.com/articles/d41586-024-02003-6

The physics of fish hearing nature video 2024-07-31 | It's known fish have directional hearing but the exact mechanism has eluded researchers for decades.Now a team of researchers have demonstrated that some fish can independently detect two components of a soundwave — pressure and particle motion — and combine this information to identify where a sound comes from.Read the paper: nature.com/articles/s41586-024-07507-9
This tiny solar-powered flyer weighs less than a paper plane nature video 2024-07-17 | Researchers have overcome efficiency and power issues to create what they believe to be the lightest and smallest sunlight-powered rotorocraft in the world.Micro aerial vehicles or MAVs could have a host of applications from environmental monitoring to search and rescue. But currently, these tiny flying machines have a problem — endurance. MAVs that weigh less than 10 grams are normally limited to around 10 minutes of flying time.To increase flying time, other types of propulsion have been tested, but these still require bulky power systems on the ground to take off, preventing any craft from freely flying.One solution could be solar power. But until now no solar powered MAV has been capable of untethered sustained flight in natural sunlight.So to solve this, researchers have developed CoulombFly, a solar-powered MAV propelled by a new extremely efficient electro-static motor and powered by incredibly light solar panels.Read the paper: nature.com/articles/s41586-024-07609-4
A glass that builds and heals itself nature video 2024-06-12 | Researchers have discovered that a peptide, when mixed with water, can self assemble into a rigid glass. Peptides are chains of amino acids, like smaller versions of proteins, and they make for attractive chemical building blocks due to their ability to self-assemble into structures with unique properties. Normally these structures are crystalline in nature — not much use if you want a glassy material.But while looking for something else entirely, a team of researchers discovered that a certain peptide will develop unusual bonds with water, allowing it to form into a glass-like structure. What’s more, the unique properties of this peptide glass allow it to self heal if cracked, and act as a strong adhesive between water-loving surfaces.Read the paper: nature.com/articles/s41586-024-07408-x
Laser-powered bullets reveal surprising metal hardness nature video 2024-05-22 | Conventional thinking suggests that metals soften as they warm. But this isn't always true, as researchers have succeeded in demonstrating that under extreme conditions, metals actually get harder as they get hotter.By shooting metal targets with tiny, laser-powered projectiles, this team was able to create incredibly high strain rates. Under these conditions a property called drag strengthening comes into play giving rise to metals that behave in counterintuitive ways, and could inform high speed manufacture or aerospace engineering.Read the paper: nature.com/articles/s41586-024-07420-1
Controlled failure: The building designed to limit catastrophe nature video 2024-05-15 | Catastrophic building collapse can have many causes, but the outcome is all too familiar; a loss of lives and the destruction of infrastructure that can have a long lasting effect on a community.Current guidelines suggest extensive structural connectivity within a building is the best way to prevent disaster. This allows for a redistribution of weight should part of a structure be damaged. But in certain circumstances, this interconnectedness can be a building's downfall. With a large enough initial failure, collapsing parts of the building can pull down the rest of the connected structure.So this team of researchers took a new approach, focusing not only on preventing collapse, but also managing failure if it happens. Their idea is inspired by how some lizards shed their tails to escape being eaten by a predator - a tactical sacrifice. They call it hierarchy-based collapse isolation, and they tested their theory using an experiment two storeys high.Read the paper: nature.com/articles/s41586-024-07268-5
Should the Maldives be creating new land? nature video 2024-04-24 | As climate change leads to sea level rise, low-lying island nations like the Maldives are facing an existential threat. One solution is to 'reclaim' land by relocating sediment from the ocean floor. This can provide more space for development and increase resilience to rising oceans. But many are concerned about the environmental and social impacts of such projects. In this film we explore the process, the impacts and the uncertainties around this race to adapt.Read more in the feature:
AI and robotics demystify the workings of a flys wing nature video 2024-04-17 | Machine learning and robotics have shed new light on one of the most sophisticated skeletal structures in the animal kingdom: the insect wing hinge. Unlike birds or bats, which evolved wings by adapting existing limbs, insect wings are wholly original appendages, and understanding how the complex hinge that links the insect wing to its body works has been a challenge.But now a team of researchers have combined cutting edge imaging, machine learning and robotics to build a model that is shedding new light on the structure.

No sweat: Moisture-wicking device keeps wearable-tech dry nature video 2024-03-27 | Wearable electronics have a sweat problem. Most electronic materials aren’t permeable, and if a device isn’t breathable, sweat can start to build up on the skin. That’s uncomfortable for the user, and not great for the device which could lose signal quality, or just fall off.Breathable electronics do exist, but the technology is in its infancy. Now though a team of researchers have developed a new breathable platform that could be easily integrated with cutting edge electronics.Read the paper: nature.com/articles/s41586-024-07161-1
Cancer-busting vaccines are coming: heres how they work nature video 2024-03-27 | Most vaccines work by teaching the immune system to recognize harmful viruses or bacteria before a person gets infected and becomes unwell. A few cancer vaccines do this, too. For example, a vaccine is given to young people as protection against human papillomaviruses that can cause cervical cancer. But scientists are also developing cancer vaccines that could be used as treatments, after cancer has been found. These vaccines work by teaching the body's immune system to distinguish between healthy cells and abnormal cancer cells. To do this, researchers need to identify proteins that are made by cancer cells but not by healthy cells. These proteins can be used like a barcode. The vaccine teaches the body's immune cells to 'read' the barcode, as a way of identifying the cancer. This video explains how these vaccines are made, and the pros and cons of various types of cancer vaccine.Read more here: nature.com/collections/cancer-vaccines-outlineThis Nature Video is editorially independent.

Building a heart atlas nature video 2024-03-13 | The heart is the first organ to develop, but despite its importance, scientists know surprisingly little about exactly how its cells are arranged.Now a team of researchers have combined RNA sequencing and cutting edge imaging technology to map the heart in more detail than ever before.They hope that this ‘atlas’ will allow scientists to tackle congenital defects, which are a leading cause of death in infants.Read the paper: nature.com/articles/s41586-024-07171-z
The bees that can learn like humans nature video 2024-03-06 | Scientists have long accepted the existence of animal culture, be that tool use in New Caledonian crows, or Japanese macaques washing sweet potatoes.One thing thought to distinguish human culture is our ability to do things too complex to work out alone — no one could have split the atom or travel into space without relying on the years of iterative advances that came first.But now, a team of researchers think they’ve observed this phenomenon for the first time outside of humans, in bumblebees.Read the paper: nature.com/articles/s41586-024-07126-4
Why human brain cells grow so slowly nature video 2024-01-31 | Growing human neurons in the lab can be a time-consuming process. Some cortical cells take years to reach maturity - many times slower than the equivalent cells in a mouse. Researchers have been exploring some of the mechanisms that could be behind these very different timescales of growth - and have found a kind of epigenetic ‘braking’ effect that slows maturation. Manipulating this ‘brake’ could allow scientists to speed up the study of older brain cells in a dish.Read the paper: nature.com/articles/s41586-023-06984-8
‘Like a moth to a flame’ — this strange insect behaviour is finally explained nature video 2024-01-30 | Moths love a light bulb. And it’s not just moths — all sorts of insects congregate around artificial lights at night. But what makes these lights so apparently attractive?Previous explanations have included the idea that confused insects are attempting to use the moon to navigate, or that they’re being drawn to the heat rather than the light itself. Now, advances in camera technology have allowed researchers to study the flight of these insects in more detail than ever before, and revealed a new solution to the mystery.Footage shows that flying insects seem to be twisting to keep their back to the light - a reflex known as a dorsal light response. Rather than being attracted towards it, they find themselves stuck in a loop flying around it…Read the paper in full nature.com/articles/s41467-024-44785-3For more stories like these sign up for the Nature Briefing: An essential round-up of science news, opinion and analysis, free in your inbox every weekday: go.nature.com/371OcVF
Super-propulsion: How sharpshooting insects flick their pee nature video 2023-12-27 | Sharpshooters are tiny insects capable of extraordinary feats. They feed on xylem fluid which is about 95% water and as a result they produce a lot of urine which they need to expel, and they do so using some pretty nifty physics called super propulsion. By taking advantage of the unique properties of water at this scale, sharpshooters can flick droplets of urine away from their bodies at speeds faster than they can move, saving energy and allowing them to keep feeding. This is the first time super propulsion has been seen in a natural system and researchers say it could provide inspiration for new ways to keep tech dry.Read more: nature.com/articles/s41467-023-36376-5

The rubber that stops cracks in their tracks nature video 2023-12-13 | Modern manufacturing needs stiff rubbers that can resist deformation for components like shock absorbers and drive belts.But the stiffer rubber becomes, the more likely it is to crack under stress, which is a tough problem for researchers; the point at which cracks begin to propagate under repeated stress, known as the fatigue threshold, has stayed the same for decades.But now a team of researchers have created a new type of rubber with a fatigue threshold 10 times higher than before, by entangling polymers in the rubber’s structure.Read the paper here nature.com/articles/s41586-023-06782-2For more stories like these sign up for the Nature Briefing: An essential round-up of science news, opinion and analysis, free in your inbox every weekday: go.nature.com/371OcVF
Super hot plasma made easy with stabilising fibres nature video 2023-11-29 | CORRECTION: The video incorrectly states that an 'extremely high voltage' is used to create the plasma. In fact the use of carbon fibres in this device decreases the required voltage to less than 50 volts.In a plasma electrons separate from atoms and create a soup of charged particles that can be extremely hot and bright. This is particularly useful for manufacturing certain types of high temperature materials - and for experimenting with new materials. But plasmas can be hard to control, and existing methods require specialist equipment. Now a new technique using carbon fibres has been shown to be able to create a stable plasma with a uniform temperature - and the researchers say their kit will be much easier to construct in physics labs around the world.Read the paper here: nature.com/articles/s41586-023-06694-1
The 3D printer that crafts complex robotic organs in a single run nature video 2023-11-15 | 3D printing technology has made huge breakthroughs in recent years, able to quickly produce everything from small plastic components to entire buildings. But one area that remains a challenge is the construction of intricate mechanical devices which require multiple materials and moving parts.This new printer combines inkjet printing technology with error correction guided by machine vision to tackle this challenge and construct sophisticated functional devices.By scanning and adjusting layer by layer as it prints, it can maintain speed and accuracy while its multiple print heads lay down different materials side by side. And while the researchers behind the technique, called vision-controlled jetting, have started by demonstrating prints with soft and rigid plastics, the machine has the potential to print electronics or even cellular scaffolds for tissue engineering.Read the research paper here: nature.com/articles/s41586-023-06684-3For more stories like these sign up for the Nature Briefing: An essential round-up of science news, opinion and analysis, free in your inbox every weekday: go.nature.com/371OcVF
Could a robot chemist create oxygen on Mars using AI? nature video 2023-11-15 | If humans are ever to build settlements on Mars, they will need oxygen, to breathe, but also to allow rocket fuels to burn, to allow for return missions. But oxygen makes up only a tiny percentage of the Martian atmosphere, and transporting oxygen there from Earth is not a practical solution. Instead scientists have pinned their hopes on generating oxygen on the red planet, and this new robotic chemist aims to do just that. Powered by AI, it autonomously creates catalysts using locally sourced materials, capable of producing as much oxygen as a tree.Read more:
How would a starfish wear trousers? Science has an answer nature video 2023-11-01 | Starfishes are weirdly shaped animals. Scientists have long puzzled over how a starfish body equates to the more typical animal arrangement of a head on one end and trunk or tail on the other. Humans wear trousers on the bottom of their trunks, so you could extrapolate out from that to suggest solutions to the 'trouser question' for dogs, horses, spiders and even slugs.

How to recycle a wind turbine in a test tube nature video 2023-04-26 | Wind turbine blades are huge, strong and hard to recycle. As the world's use of wind energy grows, researchers are searching for better ways to make use of old, decommissioned wind turbine blades. Now researchers in Denmark are using chemistry to find ways to break down the tough epoxy plastic that make up the blades, and recover useful materials for producing future wind turbines.Read the paper: nature.com/articles/s41586-023-05944-6
Mutated neuroreceptor lets octopuses taste with their arms nature video 2023-04-12 | Octopuses hunt for prey in cracks and crevices along the seabed using ‘taste-by-touch‘ - the ability to detect chemical signals simply by touching them. Now researchers have identified the molecular makeup of a chemo-tactile receptor that makes this possible. In this film we explore the surprising origins of this receptor, and ask whether molecular evolution can explain octopuses’ unique behaviours.

Acute kidney injury explained nature video 2023-03-29 | Acute kidney injury, known as AKI, is surprisingly common, especially among people in hospital.It happens when the kidneys stop working properly, often because of a change in blood flow due to surgery or an infection. If the kidneys do not recover quickly, it can turn into a chronic condition. Therefore, physicians would like better ways to prevent, diagnose and treat AKI.In this animation, we explain how risk algorithms, research into biomarkers and new drugs offer hope to patients and physicians.Learn more about AKI nature.com/collections/acute-kidney-injury-outlineThis Nature Video is editorially independent.

The driving test for driverless cars nature video 2023-03-22 | How do you test whether a fully autonomous, self-driving car can cope with dangerous situations? In the real world accidents and near-misses are relatively rare — rare enough that it would take a lot of testing to see how a driverless car might react to different scenarios. Now a group of researchers has developed a new way to test autonomous vehicles, by surrounding them with virtual reality obstacles controlled by AIs. These virtual cars, trucks, deer, cyclists and pedestrians have been trained to recreate a variety of dangerous events based on real world data. The system is already being used to test and train autonomous vehicles currently in development.Read the paper: nature.com/articles/s41586-023-05732-2 For more stories like these sign up for the Nature Briefing: An essential round-up of science news, opinion and analysis, free in your inbox every weekday: go.nature.com/371OcVF
The mystery of the disappearing lymphocytes nature video 2023-03-15 | Lymphocytes are immune cells that play vital roles in fighting infections. The most well-known lymphocytes are the T cells and B cells of the adaptive immune system. In the 1950s and 1960s, scientists performed experiments to follow lymphocytes on their journey around the body, which helped us to work out where they go and what they do. This work laid the foundation for everything we know about T cells today, including how they become activated to fight infections and how they form memory populations that provide long-lasting immunity.
