BBC Inside Science

James Lovelock is one of the most influential thinkers on the environment of the last half century. His grand theory of planet Earth - Gaia, which is the idea that from the bottom of the Earth's crust to the upper reaches of the atmosphere, Earth is one giant inter-connected and self-regulating system, has had an impact way beyond the world of science. As Lovelock celebrates his hundredth birthday...

Dr Adam Rutherford uncovers the worrying number of false positive results that the DNA sequencing technologies used by 'direct to consumer' genetic test kits are producing. Many of these tests offer analysis on your ancestry, but some also offer to check you out for the likelihood of you being at risk of some genetic diseases like cystic fibrosis or certain types of breast cancer. The tests look f...

Code-breaker and father of computer science, Alan Turing has been chosen to celebrate the field of science on the new £50 note. Adam Rutherford asks Chief Cashier at the Bank of England, Sarah Johns how and why he was selected and he asks Sue Black, Professor of Computer Science and Technology Evangelist at Durham University, who campaigned to save Bletchley Park, what this accolade means. In 1969...

A new study shows that 210,000-year-old skull found in Greece is the earliest evidence for modern humans in Eurasia. A second skull found in the same site is found to be a Neanderthal from 170,000 years ago. These findings suggest that modern humans left Africa earlier and reached further than previously thought. Analysing moon rocks The Apollo missions were scientific explorations, bringing back...

Global Food Security Maia Elliot is an analyst and writer for Global Food Security, who recently held a competition for young food researchers to present their work in a compelling way in less than 3 minutes. Maia and the winner, Claire Kanja of Rotha...

Rinderpest – Sequence and Destroy Last week the UK’s Pirbright Institute announced that it had destroyed its remaining stocks of the deadly cattle virus Rinderpest. This repository was one of the biggest remaining stores of it since it was announced in 2011 that vaccines had eradicated it in the wild. Dr Michael Baron, amongst others, has been arguing for years that because we can now obtain a ful...

Net-Zero Carbon Target The UK is set to become the first member of the G7 industrialised nations group to legislate for net-zero emissions after Theresa May’s announcement this week. The proposed legislation would commit the UK’s greenhouse gas emissions to ‘net-zero’ by 2050, which would mean that after reducing emissions as much as possible, any remaining emissions would be offset through scheme...

Some people have a genetic mutation in a gene called CCR5 that seems to bestow immunity to a form of HIV. This is the mutation which controversial Chinese scientist Jianqui He tried to bestow upon two baby girls last year when he edited the genes in embryos and then implanted them in a mother. A paper in the journal Nature Medicine this week uses data from the UK Biobank to look at the long term h...

Adam Rutherford and guests at the Hay Festival discuss how maths underwrites all branches of science, and is at the foundation of the modern world. His guests are the following. Professor Steve Strogatz, of Cornell University, the author of a new book on calculus, Infinite Powers. He’s worked on all kinds of problems including some biological ones such as the shape of DNA, how fireflies create lig...

New CFC emissions Researchers say that they have pinpointed the major sources of a mysterious recent rise in a dangerous, ozone-destroying chemical. CFC-11 was primarily used for home insulation but global production was due to be phased out in 2010. But scientists have seen a big slowdown in the rate of depletion over the past six years. This new study published in the Journal Nature says this is...

The Hubble Constant The Hubble constant is the current expansion rate of the universe but it seems to have changed over time. Hiranya Peiris, Professor of Astrophysics from University College London and Adam Riess, Professor of Physics and Astronomy from Johns Hopkins University, are both using different methods to obtain a value for the Hubble constant. But there is a discrepancy in their values....

A damning House of Lords' report into the provision of forensic science in England and Wales makes for uncomfortable reading for some but is broadly welcomed by those in the field. Prof. Niamh Nic Daeid, one of many who gave evidence to the Science and Technology Committee, gives her reaction and suggests how a combination of unsatisfactory regulation, profit and austerity pressures in a uniquely...

In 2018, the International Association of Athletics Federations (IAAF) introduced new eligibility regulations for female athletes with differences in sex development (DSDs). These regulations are based on the contention that women with high levels of endogenous testosterone and androgen sensitivity have a performance advantage over their peers. South African middle distance runner, Mokgadi Caster...

Patients who suffer neurological impairments preventing them from speaking potentially face a severely limited existence. Being able to express yourself in real time is a large part of our identity. In the journal Nature this week, scientists from the University of California, San Francisco, report a new technique for synthesising speech based on measurements of neural signals taken from the brain...

The horror of the blazing Notre-Dame cathedral in Paris has been slightly quenched by the fact that so much of the French landmark has been saved. But what was it about the structure of the roof, with some the beams dating from the 13th century, that meant it burned like a well-stacked bonfire? Guillermo Rein is Professor of Fire Science at Imperial College London , and he explains to Adam Rutherf...

"We have now seen the unseeable" according to scientists who are part of the Event Horizon Telescope group. The international team has released a picture of the first black hole. Data gathered from an array of over 8 radio telescopes has been crunched to create a picture of the super-hot plasma surrounding the black hole M87. It shows extremely excited photons on the brink of being swallowed up by...

About 66 million years ago an asteroid at least 6 miles wide crashed into the Earth, in the shallow sea that is now the Yucatan Peninsular in Mexico. It gouged the Chicxulub crater 18 miles deep; threw 25 trillion tonnes of debris into the atmosphere, much of which was hotter than the Sun, created huge seismic waves and massive tsunamis churning the Gulf of Mexico, tearing up coastlines and peelin...

One of the longest running insect pollinator surveys in the world, shows that a few generalist pollinators are on the increase, whereas specialist insects are declining. Using data collected by volunteers across Great Britain to map the spatial loss of pollinator insect species, the study by the CEH (Centre for Ecology and Hydrology) measured 353 wild bee and hoverfly species across the country. T...

30 years ago Tim Berners-Lee invented the World Wide Web as a way to let physicists share their papers and data on a distributed network. It's changed a lot since then and not all for the better. Dominant technology companies monopolise our data and many, including Berners-Lee are worried about the growth of state sponsored hacking, misinformation and scamming. One solution is to re-decentralise t...

When the news broke last December that Chinese biophysicist He Jiankui had successfully edited the genomes of twin girls using the technique known as CRISPR-Cas9, scientists and the public were rightly outraged that such a procedure had taken place. Jiankui is currently being investigated by Chinese authorities for breaking legal and ethical guidelines on human genome editing. This week, in the jo...

An HIV-1 sufferer, who had developed aggressive cancer, and underwent a revolutionary stem cell transplant, has been declared HIV resistant. It's been 18 months since the 'London patient' underwent a stem cell transplant of donated HIV resistant cells. This has only happened once before, in the case of the ‘Berlin Patient' – who, after two transplants, has now been HIV and cancer free for 10 years...

Efforts to cut emissions of carbon dioxide (CO2) and tackle climate change in many developed economies are beginning to pay off, according to research led by Corinne Le Quere at the Tyndall Centre at the University of East Anglia. The study suggests that policies supporting renewable energy and energy efficiency are helping to reduce emissions in 18 developed economies. The group of countries repr...

Nasa have called time on the 14 year mission with the Mars Opportunity rover. Curiosity is still there. But what's next for our exploration of the Red planet? Adam asks Senior Strategist in Space Systems at Airbus, Liz Seward and BBC space correspondent, Jonathan Amos. Airbus are working with the European and Russian Space Agencies on the next rover, part of the Exomars mission. This new rover is...

A very strongly worded, meta-review paper (looking at 73 historical reports from around the world published over the past 13 years) has just been published looking at the fate of insects around the world. The researchers have collated other people’s research, including the big 27 year study from Germany, that showed 75% loss of insects by weight (biomass). The basic headlines are quite scary: 40%...
