Promoting social causes online can mobilise millions and raise huge sums of money. But it only leads to long term changes if the campaigns don't fizzle out prematurely. Social psychologist, Sander van der Linden, University of Cambridge, thinks he's found the formula for social media campaigns to be effective in the long run, detailing what he calls "viral altruism" in a study published in Nature Human Behaviour. Ricky Nathvani went to go find out exactly what it is... Like this podcast? Please help us by supporting the Naked Scientists

A tiny sensor capable of transmitting information from inside the body and powered by stomach acid has been unveiled by US scientists. The device was tested in a pig over the course of a week wirelessly transmitting its body temperature every twelve seconds to an external receiver. The MIT and Harvard-based team behind the work, which was published this week in Nature Biomedical Engineering, say this represents a step towards safer, cheaper ingestible sensors that could even be used to dispense drugs inside the body. Dr Giovanni Traverso of the Brigham and Women's Hospital at Harvard Medical... Like this podcast? Please help us by supporting the Naked Scientists

Some viral infections are more lethal in men than in women. This is usually linked to differences between male and female immune systems. However, mathematical modelling of the different ways some viruses can spread in men and women suggests it may, in fact, benefit the virus to tailor its aggression based on who it is infecting, as Vincent Jansen from Royal Holloway University explains to Tom O'Hanlon...

2016 was another record-breaker in terms of global temperatures, and it's part of a longer-term trend which has seen 15 of the hottest years on record occur since 2001. One victim of this warming is the Artic, where sea ice is steadily retreating, which means that the habitats for species that live there are also radically altering. So are these organisms equipped to cope with the change? Thomas Mock, from the University of East Anglia, has been studying one marine species which use a genetic trick to achieve considerable resilience, as he explained to Tom Crawford...

A chemical found in sharks can block the process that leads to Parkinson's Disease, scientists at Cambridge University have found. Know as squalamine, the substance prevents a protein called alpha-synuclein from accumulating on and damaging the membranes of nerve cells in the brain. Dosing with squalamine protected cells cultured in a dish as well as microscopic worms that have been genetically altered to make them develop a Parkinson's-like syndrome. Chris Dobson explains...

Us humans boast about our big brains but until now, evidence has been scant to suggest that animals also benefit from having larger brains. Cambridge University's Corina Logan measured the skulls of 1314 red deer from the Isle of Rum to see if the brainy stags and does were more successful. She explained her results to Naked Scientist Tom O'Hanlon... Like this podcast? Please help us by supporting the Naked Scientists

As the saying goes, "if you don't learn from the past you're doomed to repeat it," or words to that effect; which is why understanding what has happened to the Earth's climate in the past is critical if we are to make accurate predictions about our the effects of climate change in future. So how might clams help? Well, they are among the oldest living animals on Earth, surviving for 500 years in some cases.

Carbon monoxide poisoning is the common form of poisoning worldwide. Just in the US tens of thousands of people are killed or hospitalised every year by this odourless and colourless gas, which in is boiler, stove and vehicle exhausts and is also produced during house fires. At the moment, the only treatment is oxygen, but it's not very effective and often is administered too late. Now researchers at the University of Pittsburgh have developed an antidote molecule that can circulate in the bloodstream and pull the carbon monoxide from tissues to make it safe. Mark Gladwin told Chris Smith how... Like this podcast? Please help us by supporting the Naked Scientists

An area of rainforest the size of Panama is lost every year to deforestation and we know habitat loss is probably the leading factor driving extinction today. However, another potential problem could be an increase in certain disease-causing organisms which benefit from the changing habitat. Ecosystems are complex and changes to the conditions each species needs to survive can impact on each other and throw it out of balance. Aaron Morris, from Bournemouth University and the IRD in France, has been looking at how changes in the local environment have affected populations of the bacterium... Like this podcast?

Dark energy, the mysterious unknown entity which permeates all of space makes up 68% of the universe's total energy. Despite being such a large proportion of existence we still can't directly detect it. An international group of scientists is trying to map dark energy in our night sky. But how do you map something that you can't see and what precisely is dark energy? Liam Messin spoke to Joe Zuntz from the University of Edinburgh who is involved in the project Like this podcast?

2D materials are objects that are only one or two atoms thick. Graphene is the most well known of these but many incredibly thin substances exist. These exotic materials are strong, flexible, semi-transparent and great conductors of electricity. But before they can be used in novel technologies we need efficient ways of making them. Graphite, as found in pencil leads, is made up of many layers of graphene and to isolate graphene all these layers have to be peeled away one by one until only a single layer is left. Researchers at UCL have found a new method of obtaining single 2D sheets from... Like this podcast? Please help us by supporting the Naked Scientists

We've just come to the end of anti-bullying week and with 25,000 children using Childline's counselling sessions in 2015 to talk about bulling it clearly is still a problem for the UK. This problem appears to go beyond playground trauma with research published this week showing that bullied children are more likely to be overweight at age 18.

When you were little did you ever dream of becoming an astronaut? Well Michael Foale did and he actually made it happen. Born in the UK Foale completed both his undergraduate and doctorate degrees in Cambridge before joining NASA and going on to become the most experienced UK-born astronaut.

Quantum mechanics describes the properties of light, atoms and the even smaller particles inside atoms, like electrons and protons. On these tiny scales, we observe strange effects that contradict our everyday experience and we are beginning to harness these effects to build technologies that seemed impossible before. Kerstin Gpfrich went to the 2016 National Quantum Technologies Showcase in London to find out about the latest quantum leaps in quantum technology. Like this podcast?

Compared to a lot of the objects in our solar system the Earth's Moon is a bit unusual. A new theory, published in the journal Nature, explains how the Moon got to where it is today. Professor David Rothery, from the Open University, wasn't on the paper but he took Liam through what Matja Cuk, the study's lead author had done. He started by explaining what makes the Moon such a space oddity... Like this podcast? Please help us by supporting the Naked Scientists

Plants can be good for the planet, nice to look at and often pretty tasty. But what if they were also high tech sensors that we could harness to detect harmful chemicals and even explosives in groundwater or the air around them? Michael Strano and his group from MIT have produced just such a "bionic" plant by engineering spinach plants to produce more, or less, infrared light in the presence of certain chemicals.

The Paris agreement is an international climate change treaty signed earlier this year by 192 countries and it aims to mitigate man-made global warming. It kicks in from this week. But will its targets be sufficient? Over half of the Arctic sea ice area has been lost in the past 40 years and we may yet lose all of it. That's according to a new study from the Max Plank Institute for Metrology in Hamburg. Kerstin Gpfrich spoke to study's author Dirk Notz. Like this podcast?
