From defending their young to teaching them how to hunt, motherhood is arguably one of nature's most demanding jobs in the animal kingdom and BBC is showing us some good examples. Maybe you learn something from the video and you may be a better mother for your children.

The proportion of people without children was growing around the world and the end of last year, December 2024, when the video was uploaded, and the situation has not changed in the last months. BBC people were trying to find out in this Global Story podcast. So, why? Before watching the video you may read my opinion: climate change is one of the reasons, the economical and social context is another, and education is a third reason. They do varies in the world, at least the last two of them, but they have similar results in different countries. You can take a look around you to see how many fat, sedentary and drunk people you have around you and you may reach your own conclusion.

Yes, they do, because microbes are in hard competition - some may say they are living a very long war against each other. Penicillin, for example, is based on fungi protecting themself against bacteria, and penicillin is the base of our current antibiotics. In this lecture recorded by Robin May on 2nd October 2024 at Barnard's Inn Hall, London, for the Gresham College, he is talking us about the microbian immune systems and how they are living among us and inside us.

Nature is always changing and adapting to its environment, and it can become strange and stranger from time to time. Grown all over the mountains of southern Mexico, this giant maize presented by BBC and its mysterious mucus could help feed the planet and end farming’s toxic reliance on chemical fertilisers. As long as scientists can crack its code…

Cancer is just another mutation, but it's a mutation out of control that makes people sick and a mutation that kills people, and that makes it a problem for society. That mutation appears from different reasons, one of the being the chemicals that are in our air and our food - something that makes the cancerigens - and tere are some ways to avoid cancer (at least in some degress). There is also natural radioactivity, ultraviolet waves and viruses that can give people cancers, so there is no perfect protection yet from all of these factors.

Living alongside polar bears in the Canadian Arctic  seems to be an interesting thing, but have you thought about capturing one? Each spring since 2003, Jon Aars, senior scientist at the Norwegian Polar Institute, and his team have conducted an annual polar bear monitoring program on Svalbard - collaring, capturing and taking samples from as many bears as they can across several weeks.

After going to see the polar bears in the Canadian Arctic you may be interested in finding out how our nature reclaims 'apocalyptic' derelict coal mine. In each country there are places we abandoned and there are many plants and animals that have been moving in after we are gone.

Considering that the world is chaning and the climate is warming up, considering that in the polar bear capital of the world, melting sea ice spells transformation and danger, I am challenging you to have a polar bear as pet. I know how dangeour this kind of pet is and how easy you can become its food, so take you time to decide - you don't need to tell me and the entire world right now.

Eating mushrooms is good, they offer us several necessary elements, but not the mushrooms are good. As a method of own protection they are toxic for many animals and they may be killing them if the animals are consuming too much mushrooms - too few animals to eat them is good for mushrooms. Watching the video, a lesson by Michael Beug and directed by Denys Spolitak, you can explore the toxicity of death cap mushrooms, and find out what makes this one species so dangerous to humans.

The human species ancestors started to move around all over the place a long time ago, before they become fully human (as we consider ourselves as humans). There are many theories that ponder the origins of Chinese facial characteristics and the professor Alice Roberts is fascinated to hear that one, in particular, poses a controversial idea: that the Chinese come from a completely different branch of the human family.

It probably is not America's ticking time bomb, it's the world's ticking bomb, but it won't have an eruption neither today neither tomorrow. Next week or next year maybe, but not this week - you have time to prepare. And, meantime, you can ask yourself how likely is an eruption of the Yellowstone Supervolcano in the USA?

The human family seems to get bigger with time, too bad that all our cousins (from the species point of view) are dead, and they have been dead a long time ago. For the moment, after re-examining fossils found in East Asia, scientists have possibly identified a new species of ancient human called Homo juluensis (the one with a bigger head - about 1700 cubic centimeters, and that bigger than the current humans).

Climate change doesn't just melt ice caps, make more storms, summers more warmer and some of the terrains sandy, it also fuels conflict, corruption and division worldwide, explains TED Fellow and journalist Peter Schwartzstein. From droughts in Syria to rising seas in Bangladesh, he explores how climate stress escalates existing social instabilities — and underscores why every effort to curb a warming world matters, no matter how small.

One cool news: the UK's biggest ever dinosaur trackway site has been discovered in Oxfordshire, England. About 200 huge footprints, which were made 166 million years ago, criss-cross the limestone floor.

 

A little piece of history that BBC is presenting us. Watching the video you can also embark on a compelling, mind-blowing, and complex journey through 300 years of history to discover the secrets of the cell - and of life itself.

Every discovery, image, and risk reveals how climate change is reshaping the most remote and fragile environments on Earth. From brown stains observed on Antarctica's ice from space to a surprising discovery, can you guess what it could be?

Our planet is filled with plastic and the people from Harvard University spoked about it. On average, we as a race produce 430 million tons of plastics every year, most of which is used only for a short period of time and then discarded. But plastic isn’t just in the environment: it’s now in our bodies.

Last month the conditions in Florida, USA, were quite bad as Hurricane Helene strengthened, and it was one of the hurricanes they were worse in the last years.  According to two studies that came out this week, storms are becoming more intense and more frequent because of the climate crisis and that's not a surprise at all - heating the planet humans are puting more and more energy into the sea, oceans and the atmosphere and that's making the atmosphere more wet and more unstable.

Human intervention in nature will change it, and many times that change is bad for some species or nature itself. As example, virtually all the UK’s rivers have been physically altered in one way or another – straightened, dammed, dredged or restrained by barriers in some way along their course.

The bogs and the swamps contain more carbon than all other ground vegetation and that's normal considering how the very wet soil interacts with the plants and their carbon. As the permafrost melts the greenhouse gases are released, which in turn accelerate global warming melting more and more ice and permafrost.
