Herring population loses migration 'memory' after heavy fishing 37:34

1 day ago37:34

37:34

00:46 How fishing activity altered the migration pattern of Herring Selective fishing of older herring has resulted in a large shift in the migration pattern of these fish, according to new research. For years, herring have visited sites on the south coast of Norway to spawn, but in 2020 a rapid shift was seen, with the fish instead visiting areas hundreds of kilometres to the north. Researchers have concluded that too many older fish have been removed from these waters, preventing the knowledge of the best spawning grounds being passed to younger, less experienced fish. This finding shows how human activity can affect animal migration, which could have serious consequences for the delicately balanced ecosystems built around them. Research article: Slotte et al. 10:37 Research Highlights Archaeologists have identified tools that the ancient Maya may have used for tattooing, and the self-assembling stable structures that may help ‘forever chemicals’ persist in nature.

00:27 Five people see ‘olo’, a brand-new colour Using a laser system to activate specific eye cells, a team has allowed five study participants to perceive a vibrant blue-greenish hue well outside the natural range of colours seen by humans. Although the setup required to accomplish this feat is currently complicated, this finding could provide more understanding about how the brain perceives colour and could one day help boost the vision of people with colour blindness. Nature News: Brand-new colour created by tricking human eyes with laser 08:30 US regulator greenlights pig-liver transplant trial The US Food and Drug Administration has approved the first trial to test whether genetically modified pig livers can be used safely to treat people with organ failure. In the initial phase of the trial, four people with severe liver failure will be temporarily connected to an external pig liver that will filter their blood. Participants will then be monitored for a year for safety and changes in liver function. The organs have been genetically modified to make them more compatible with humans. Nature News: Pig livers for people: US regulator greenlights first safety trial 14:08: A chunk of lab-grown chicken Using a designer ‘circulatory system’, a team of researchers have created what they think is the largest piece of meat grown in the laboratory yet. One of the challenges to producing larger pieces of lab-grown meat has been providing cells with sufficient oxygen and nutrients, something the team’s new setup helps overcome. They used it to grow a chunk of chicken muscle about the size of a nugget, but multiple challenges remain before meat produced in this way could make it to market.

‘Dark matter’, 'Big Bang' and ‘spin’: how physics terms can confuse researchers 33:11

17 days ago33:11

33:11

Categorizing things is central to science. And there are dozens of systems scientists have created to name everything from the trenches on the sea bed to the stars in the sky. But names have consequences. What’s in a name is a series exploring naming in science and how names impact the world. We look at whether the system of naming species remains in step with society, how the names of diseases can create stigma, and how the names chosen by scientists can help, or hinder, communication with the public. In episode three, we're looking at how the names chosen for concepts in physics can inadvertently send researchers down very specific research avenues while distracting them from others. In this podcast we hear five stories about the importance of names and how much can be lost in translation when physicists try and label the unknown.

00:46 Millimetre-sized pacemaker fits inside syringe Researchers have developed a tiny, temporary pacemaker that dissolves when no longer needed, helping to overcome some of the challenges associated with current devices. Temporary pacemakers are often required after heart surgery but implanting them can require invasive procedures. This new device is injectable, requires no external power and is controlled using light shone through the skin. The tiny pacemaker has shown promise in animal and heart models, and the team think it could also be used in other situations where electrical stimulation is needed, like the brain. Research Article: Zhang et al. 08:19 Research Highlights Measurements show that global warming is causing lakes to lose their oxygen, and a massive, 30-year analysis showing that a diet of plant-rich foods is associated with healthy ageing Research Highlight: Life-giving oxygen is wafting out of lakes worldwide Research Highlight: The best foods for healthy ageing ― and the worst 10:21 Shingles vaccine linked to reduced dementia risk A large-scale population study suggests that getting a shingles vaccine reduces the probability of someone getting dementia by around one-fifth. By taking advantage of the way a shingles vaccine was rolled out in Wales, a team were able to compare dementia outcomes in vaccine-eligible people to those born just a few weeks earlier who were ineligible. Although more tests will be needed to confirm this finding and to understand the mechanisms behind it, the team hope that vaccination against this viral infection could represent a cost-effective way to for preventing or delaying dementia.

In this episode: 00:46 Newly discovered molecule shows potent antibiotic activity Researchers have identified a new molecule with antibiotic activity against a range of disease-causing bacteria, including those resistant to existing drugs. The new molecule — isolated from soil samples taken from a laboratory technician’s garden — is called lariocidin due to its lasso-shaped structure. The team say that in addition to its potent antibiotic activity, the molecule also shows low toxicity towards human cells, making it a promising molecule in the fight against drug-resistant infections. Research Article: Jangra et al. 09:36 Research Highlights A reduction in ships' sulfur emissions linked to a steep drop in thunderclouds, and the epic sea-voyage that let iguanas reach Fiji. Research Highlight: Ship-pollution cuts have an electrifying effect: less lightning at sea Research Highlight: Iguanas reached Fiji by floating 8,000 kilometres across the sea 13:54 Assessing the nuances of humans’ biodiversity impacts A huge study analysing data from thousands of research articles has shown that the human impacts on biodiversity are large but are in some cases context dependent. The new study reveals that at larger scales, communities of living things are becoming more similar due to human influence, but at the smaller scale they are becoming more different. "These are generally unwanted effects on biodiversity," says study author Florian Altermatt, "this is one more very strong argument that stopping and reducing these pressures to halt and reverse biodiversity declines is needed."

00:46 Microsatellite makes messaging secure A tiny satellite has enabled quantum-encrypted information to be sent between China and South Africa, the farthest distance yet achieved for quantum communication. Using a laser-based system, a team in the city of Hefei was able to beam a ‘secret key’ encoded in quantum states of photons, to their colleagues over 12,000 km away. This key allowed scrambled messages to be decrypted — including one containing a picture of the Great Wall of China. The team’s system is drastically smaller and cheaper that previous attempts, and they think it represents a big step towards the creation of a global network of secure, quantum communication.
