Around 500 million people are estimated to be in period poverty, lacking adequate access to sanitary products. Many of these people rely on donations, but this is far from a long-term solution. To tackle this researchers have developed a method to extract absorbent materials for menstrual pads from a common plant, Agave sisalana. The researchers say that their method can be performed using local techniques and has a lower environmental impact than the manufacture of other period products. They're aiming to scale-up this approach to help those in period poverty.Research Article: Molina et al.Subscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.

In this episode:00:46 Machine vision enables multi-material 3D printing3D printers are capable of producing complex shapes, but making functioning objects from multiple materials in a single print-run has proved challenging. To overcome this, a team has combined inkjet printing with an error-correction system guided by machine vision, to allow them to print sophisticated multi-material objects. They used this method to make a bio-inspired robotic hand that combines soft and rigid plastics to make mechanical bones, ligaments, and tendons, as well as a pump based on a mammalian heart.Research article: Buchner et al.News & Views: Multi-material 3D printing guided by machine visionVideo: The 3D printer that crafts complex robotic organs in a single run07:49 Research HighlightsCitizen-scientists help identify an astronomical object that blurs the line between asteroid and comet, and how a Seinfeld episode helped scientists to distinguish the brain regions involved in understanding and appreciating humour.Research Highlight: Citizen scientists find a rarity: an asteroid trying to be a cometResearch Highlight: One brain area helps you to enjoy a joke — but another helps you to get it10:31 Assessing the effectiveness of lifestyle interventions for diabetesType 2 diabetes affects hundreds of millions of people around the world and represents a significant burden on healthcare systems. But behaviour change programmes — also known as lifestyle interventions — could potentially play a large role in preventing people from developing type 2 diabetes. This week in Nature a new paper assesses how effective this kind of intervention might be.

In this episode:00:46 Modifying a fungal drug to make it less toxicAmphotericin B is a drug used to treat life-threatening fungal infections. But while it is effective against many fungal species, it is also extremely toxic to kidneys, meaning it is mostly used as a drug of last-resort. This week, a team has unpicked the mechanism behind the drug’s toxicity, allowing them to modify it and reduce side effects in human kidney cells.

In this episode:00:47 An automated way to monitor wildlife recoveryTo prevent the loss of wildlife, forest restoration is key, but monitoring how well biodiversity actually recovers is incredibly difficult. Now though, a team have collected recordings of animal sounds to determine the extent of the recovery. However, while using these sounds to identify species is an effective way to monitor, it’s also labour intensive. To overcome this, they trained an AI to listen to the sounds, and found that although it was less able to identify species, its findings still correlated well with wildlife recovery, suggesting that it could be a cost-effective and automated way to monitor biodiversity.Research article: Müller et al.12:30 Research HighlightsResearchers develop algae-based living materials that glow when squeezed, and a 50-million-year-old bat skull that suggests echolocation was an ancient skill.Research Highlight: Give these ‘living composite’ objects a squeeze and watch them glowResearch Highlight: Fossilized skull shows that early bats had modern sonar15:11 Briefing ChatA brain imaging study reveals how high-fat foods exert their powerful pull, and how being asleep doesn’t necessarily cut you off from the outside world.Nature News: Deep asleep?

In this episode:00:47 An RNA-based viral system that mimics bacterial immune defencesTo protect themselves against viral infection, bacteria often use CRISPR-Cas systems to identify and destroy an invading virus’s genetic material. But viruses aren’t helpless and can deploy countermeasures, known as anti-CRISPRs, to neutralise host defences. This week, a team describe a new kind of anti-CRISPR system, based on RNA, which protects viruses by mimicking part of the CRISPR-Cas system. The researchers hope that this discovery could have future biotechnology applications, including making CRISPR-Cas genome editing more precise.Research article: Camara-Wilpert et al.09:05 Research HighlightsCarved inscriptions suggest a queen named Thyra was the most powerful person in Viking-age Denmark, and the discovery of a puffed-up exoplanet that has just 1.5% the density of Earth.Research Highlight: Runes on Viking stones speak to an ancient queen’s powerResearch Highlight: ‘Super-puff’ planet is one of the fluffiest worlds ever found11:38 Modelling the future of Greenland’s ice sheet meltClimate-change induced melting of Greenland’s vast ice sheet would contribute to 7m of sea level rise. But it has been difficult to calculate how the ice sheet will respond to future warming. This week, a team suggest that abrupt ice loss is likely if the global mean temperature is between 1.7 °C and 2.3 °C above pre-industrial levels. Keeping temperature rise below 1.5 °C could mitigate ice loss, if done within a few centuries, but even a short overshoot of the estimated threshold could lead to several metres of sea-level rise.Research article: Bochow et al.17:50 Briefing ChatA massive reproducibility exercise reveals over 200 ecologists get wildly-diverging results from the same data, and how melting simulated lunar-dust with lasers could help pave the Moon.Nature News: Reproducibility trial: 246 biologists get different results from same data setsNature News: How to build Moon roads using focused beams of sunlightSubscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.

Australia's swamp tortoise is one of the most endangered species in the world. This species lives in wetlands that are under threat due to rising temperatures and a reduction in rainfall.In an effort to save the tortoise, researchers are trialling a controversial strategy called assisted migration. This approach has seen captive-bred tortoises released in other wetlands some 330 kilometres south of where they are naturally found. The aim is to see whether the animals can tolerate cooler climates, and whether this new habitat might ensure the species’ future as the planet warms.While many conservation biologists and land managers have long resisted the idea of assisted migration, attitudes are changing and other projects are beginning to test whether it can protect protect animals at risk from climate change.This is an audio version of our Feature: These animals are racing towards extinction.

Sewage is a big problem in many countries, people bring tons of plastic bottles and other trash into their homes. The used bottles are often taken to the recycling centers where they are sorted depending on their material. Now you can check and gain more interesting things about the education. But some of them end up in sewers as well, which means that sewage will be an important source for COVID detection. The best part is that this type of research can be applied to the environmental proteomics field, which has barely been considered before!

From an educational perspective, Coronapods are anther example of a loss that impacts individuals and society. To check this and get more new skills for business. Their natural distribution patterns have resulted in a serious damage to the native species of the Cape region, but that doesn't even account for their ability to decimate agricultural farming practices by targeting other crops which they consume rather than reproducing in numbers large enough to harm a farm.

There are more than just private schools and some of them comply with the same guidelines as public ones. There is a gap between private and public because there is no state control over these institutions, who can set their own curriculum, hire staff and have the freedom to provide services without regards to those who don't pay them! I say you can check and learn more about the education. Students are trapped at COVID's whims because they can't afford alternative education.
