Skulls give researchers a great deal of insight into how an animal might have evolved, and skulls can be sensibly compared between species and groups of animals. The 10,000 species of bird around the world are what’s left of an even more diverse group, the dinosaurs. But research on their skulls has revealed that despite the birds’ exceptional diversity, they evolve far more slowly than their dinosaur relatives ever did. This is one of the findings of a huge skull mapping project at the Natural ...

Over the next couple of weeks almost all children in the UK will be back to school. But the pandemic hasn’t ended, and we are far from having a complete understanding of how this virus works, including how it is transmitted and how it affects younger people. Pretty much everyone is in agreement that kids need to be back at school, as the costs of not being physically in classrooms are great - for the education of kids, for their mental health, and for the finances of parents needing to work. But...

Red clay bricks are among the most ubiquitous building materials worldwide. Julio D'Arcy, a chemist at Washington University in St. Louis, Missouri, describes to Adam Rutherford how he and his team have turned ordinary house bricks into energy storage units that can power home electronic devices – thanks to the red iron oxide (rust) pigment and a conductive plastic nano-material infused into the bricks These new ‘smart bricks’ can be charged to hold electricity a bit like a battery. As the pande...

COVID19 is a chilling reminder of how pathogens from animals can jump into humans. But it’s not the first time. SARS, Ebola, West Nile virus and bubonic plague are all serious infectious diseases that sat in a host species before crossing to us. But what causes this to happen? Individual case studies suggest that we are partly to blame in the way we use the land, either through urbanisation or agriculture. But how widespread is this, and do our global patterns of land use systematically put us a...

Adam reveals new research which overturns received wisdom about how sperm swim. More than three centuries after Antonie van Leeuwenhoek peered down his early microscope to observe human sperm or ‘animalcules’ swimming with a ‘snakelike movement, like eels in water’, high-tech observations now reveal that this was, in fact, an optical illusion. Hermes Gadelha from Bristol University used 3D microscopy, a high-speed camera and mathematics, to reconstruct the true movement of the sperm tail. Much t...

The Science Museum Group looks after over 7.3 million items. As with most museums, the objects you see on display when you visit are only the tip of the iceberg of the entire collection. Up until now, many of the remaining 300,000 objects have been stored in Blythe House in London. But now the collection is being moved to a purpose-built warehouse in Wiltshire. The move is a perfect opportunity for curators to see what’s there, re-catalogue long hidden gems and to conserve and care for their tre...

A pre-print is a way for scientists to get their work out quickly for other scientists to comment on and debate. But pre-prints are not peer reviewed; they have not undergone the scrutiny of reviewers and journal editors. They're generally seen as a good thing, but are just a step on the way for science to be verified and published. But it's important to note that the science can be wrong or sloppy in pre-prints, so they have never really been part of the process by which science is disseminated...

Science is all about self-reflection. Scientists constantly check themselves, share their work, and check each other’s data. But how robust is the science upon which civilisation is built, the science which has mapped genomes, cured diseases, split atoms and sent people to the moon? Adam talks to Stuart Ritchie, a psychologist from Kings College London, about his new book Science Fictions which explores everything from biases and human fallibility, to outright fraud. He also talks to microbiolog...

Is the UK losing its way when it comes to satellite navigation? There's GPS from the US, but other countries and regions, including Russia, China, India and Japan, either have, or are building, satellite navigation systems of their own. The EU has Galileo, but with Brexit, Britain is no longer involved. The Government has announced that it’s just acquired a satellite technology company called OneWeb. It’s primary role is enhanced broadband, but there’s talk of adding in a navigation function to ...

As we’re beginning to understand more about SARS-CoV-2, the virus that causes COVID-19, we’re hopefully starting to get some clues on how to deal with the next viral pandemics, and even look at ways of stopping them from happening. To do this, we have to go back to where the virus jumped from its animal host into humans. Like this current coronavirus, many of the pandemic viruses (SARS, MERS HIV, Ebola…to name a few) are zoonotic diseases. They start in wild animals and evolve to jump to humans ...

Adam Rutherford is back to celebrate the 20th anniversary of one of the most ambitious and revolutionary scientific endeavours of all time - the Human Genome Project. Its scope and scale was breath-taking, set up to read every one of the 3 billion nucleotides, or letters of genetic information, contained within the DNA in every cell of the human body. It took seven years, hundreds of scientists, cost almost $3 billion and, amazingly, came in under budget and on time. Adam reflects back on that m...

Throughout the pandemic, we've seen an explosion in information about the science of the virus, SARS-CoV-2, and the disease it causes, COVID-19. An article online, or a text forwarded, could be true and sounds about right, but how do you know that it's accurate? When scrolling through your social feed, how do you decipher fact from fiction? A new report, by Kings College London and Ipsos MORI, reveals that those of us who get our news from social media are more likely to believe misinformation a...

As the UK gradually begins to ease out of lockdown, Marnie explores how engineers are hoping to reduce the spread of Covid-19. We’ve learned how infected people exhale droplets and aerosols, containing the virus, and how we can then either inhale them, or transfer them to our faces by touching contaminated surfaces. Many shops already have screens and physical barriers, while schools and offices are re-configuring desks and walkways. What role does the environment play in our overall risk of bec...

As the lockdown eases and some children, in preschool and primary years, start heading back to school, what impact will this have on the pandemic, how will we know and is there anything we can do about it? Marnie Chesterton talks to Professor of Mathematical Biology at Cambridge University, Julia Gog, who co-chaired the group that advised the government on the impact of easing school closures. She explains why the limited opening of schools provides a golden opportunity to learn about its impact...

Inside Science this week is all about our information - the stuff we volunteer and the traces our everyday movements leave behind. With the launch of NHS Test and Trace across England, if you start to feel unwell with suspected Covid-19 and call a new NHS hotline 119, you’ll be tested for the virus. Your close contacts will be traced and, if you test positive, you'll be asked to self-isolate for 7 days, and your contacts asked to quarantine for 14 days. The route to those close contacts is curre...

R seems to have found its way into the newspapers and on Radio 4 as if it’s a word, or a letter, that we should all be familiar with and understand. As part of the government’s briefing on Sunday, it appeared in a pseudo-equation, the infographic - 'COVID alert level = R + number of infections' - the Government called R the 'Rate of Infection', but it is commonly known as the 'Reproduction Number'. So what exactly is R, and what does it do? Mathematical Biologist, Kit Yates, from the University ...

Advice about whether the public should wear face masks, to protect against infection by the coronavirus, differs around the world. In Europe, policy recommendations are mostly geared towards homemade masks. As this country waits to find out how we’ll venture out of lock down, should we be wearing face masks out in public too? The government’s mantra throughout the pandemic has been “follow the science” but on this issue there is ongoing debate, with strongly held and differing views. The Royal S...

This week, the Government’s target to be testing 100,000 a day for COVID-19 looks like it won’t be met. But we’ve heard about many people who experienced the virus mildly, or who’ve tested positive with no symptoms at all. If you really want to know who has had the virus, the only way to tell for certain is with an antibody, or serology, test. Describing how they work is Professor of Virology at Nottingham University, Jonathan Ball. Eleanor Riley, Professor of Immunology and Infectious Disease a...

Every death is a tragedy for grief-stricken families, but every set of statistics is an opportunity to understand the virus and the disease Covid-19 a bit more. In fact gathering these data, quickly and accurately, is a priority at the moment, up there with developing a vaccine and rolling out widespread testing.

While the world is dealing with the coronavirus outbreak, those who are concerned about the environment are saying that an arguably bigger crisis is being side-lined. Climate change, or climate breakdown, is still happening. Just like the Covid-19 pandemic, it will be the poorest people in the poorest countries that pay the highest price for the breakdown in our climate. But can we learn something from the current lockdown that can be applied to climate change? Can it provide the impetus for us ...

You can’t build up a picture of Covid-19’s spread throughout the UK without testing those who might have it and those who might have already had it. Britain currently is only testing people who are hospitalised, some healthcare workers and a handful of exceptions. The upshot is that we don't have reliable numbers on how many people in the community have, or have had, Covid-19. Even self-reporting doesn’t pick up those who carry the virus, but do not show any symptoms. Professor Mike Bonsall is p...

The government have announced that the controversial cull of badgers across England will begin to be phased out in the next few years. It will be replaced by vaccinating badgers for bovine TB. The cull is intended to cut tuberculosis in cattle and has killed at least 100,000 badgers since 2013. TB in cattle is a severe problem for farmers and taxpayers, leading to the compulsory slaughter of 30,000 cattle and a cost of £150m every year. However culling is thought to have failed because frequent ...

We have known for centuries about the toxic properties of lead, and we have known since at least 1876 that birds die of lead poisoning when they eat lead gunshot (which they do, thinking its grit). To address this, in 1999, the use of lead ammunition in England was restricted. These Regulations prohibit the use of lead ammunition in certain habitat (predominately wetlands) and for the shooting of all ducks and geese, coot and moorhen. However compliance with these Regulations is low. And what ab...

For the past 220 years, Ordnance Survey have been mapping Great Britain with extraordinary accuracy. But as Gareth discovers when he visits their HQ in Southampton, GB's master map is not a static printed document. It's a 2 petabyte database which is updated up to 20,000 times a day. This adds up to 360 million updates a year.
