Immune System Surprisingly Adaptive Jun 07, 2016

Show notes

Immune cells are essential to the maintenance and repair in our bodies. However, an over-active immune system can lead to diseases such as arthritis, chronically inflamed wounds and atherosclerosis. Therefore, it is imperative to understand and carefully control our immune system activity. Our innate or non-specific immune system, acts as our body's first line of defence, these cells quickly reach the site, form a barrier, remove foreign material, and activate our more sophisticated adaptive immune system. Until now these non-specific immune cells were believed to have no memory and act in a... Like this podcast? Please help us by supporting the Naked Scientists

Universal Cancer Vaccine Jun 06, 2016

Show notes

A vaccine that can teach the immune system to attack any type of cancer is being developed and tested by scientists in Germany. Cancer affects one person in every three. It's caused by genetic damage to our cells, which leads them to grow in an uncontrolled and invasive way. But because the cancer cells are part of our own body, the immune system normally ignores them because they're regarded as non-hostile. What Ugur Sahin and his colleagues are doing is to identify a series of chemical markers that are unique to a patient's cancer cells and then turn these into a genetic message that is...

Does salt increase blood pressure? May 27, 2016

Show notes

As a nation, the UK are above the intake guidelines for salt, which, for an adult, is 6g per day. To put that into perspective, there's about half a gram in a small packet of crisps, or one ham and cheese sandwich. But what does salt do to our insides? Viknesh Selvarajah from Addenbrooke's Hospital, in Cambridge, researches the impacts of salt and has a very unique perspective on the effects of high blood pressure, as he explained to Chris Smith.

Botox Effects are More than Skin Deep May 23, 2016

Show notes

Botox is a popular cosmetic treatment where Botulin toxin-A injections paralyse your facial muscles, which relaxes smile lines and makes your skin appear younger. In comedies, it is often joked about for giving patients frozen expressions. But now, researchers say that having Botox not only makes your face difficult to read, but also impairs your ability to read the emotion of others. This stems from the theory of embodiment. For a person to process an emotion that they see, they are required to mimicking that emotion. When we see our friend smile, our face automatically smiles a little as... Like this podcast?

Boiling Frogs?! May 20, 2016

Show notes

This week we're tackling a myth sent in by listener Tim who says, "For many years I heard management gurus talking about the boiling frog syndrome.If you throw a frog into a pot of hot water it will immediately jump out. But If you put it in cold water and slowly heat it, it will boil to death " He also adds "Please don't harm any frogs disproving it!" Fortunately for Tim - and the frogs - someone has already done this experiment, or at least got as close to it as they feel ethically able to, without actually boiling any frogs alive. Kat Arney gets into hot water finding out... Like this podcast? Please help us by supporting the Naked Scientists

500 Years of Robots May 19, 2016

Show notes

Robots are everywhere, from the machines that work in factories to pop culture icons like the Star Wars droids BB8, R2D2 and C3PO. but this is nothing new. Humans have been creating robots for centuries, and a new exhibition at the Science Museum in London will be showcasing our love of these Metal Mickeys, although sadly we'll have to wait until next year for it to open. Kat Arney went along to get a sneak preview of one of the shining metal stars of the show, and also to the exhibition's human curator, Ben Russell. Like this podcast?

New link in how life began May 16, 2016

Show notes

The origins of life on earth has been a mystery since, well since life began. Researchers from Germany this week have found a crucial link in explaining how we got from the soup of chemicals on early earth to the very first cell, lending support to the so called RNA world theory. Lead researcher Professor Thomas Carell spoke to Emma Sackville about what RNA theory is and how their research supports it... Like this podcast? Please help us by supporting the Naked Scientists

Mouse Model Shows Zika Causes Birth Defects May 16, 2016

Show notes

On February 1, 2016, the World Health Organization declared Zika virus a Public Health Emergency of International Concern with the virus' continued spread through the Americas. Zika, which was previously considered to be fairly harmless, has been linked to birth defects and miscarriages in a dramatic shift that scientists are unable to explain. However, we are now one step closer to understanding this virus as the development of a new mouse model may have solved one piece of the puzzle. Connie Orbach spoke to lead researcher Michael Diamond from Washington University in St Louis. Like this podcast? Please help us by supporting the Naked Scientists

Limbs from Gills? Apr 25, 2016

Show notes

Could limbs have evolved from fish gills? While it might sound fishy, scientists from the University of Cambridge have discovered that the same genetic programme, triggered by a gene called Sonic Hedgehog, is involved in the development of limbs, fins and gills. The idea that the formation of gills and legs might be linked is actually not a new one and was first proposed more than a century ago based on the similarities in appearances of the two structures, but scientists abandoned the notion as fanciful thinking. Connie Orbach went to see researcher Andrew Gillis, who has discovered that the... Like this podcast? Please help us by supporting the Naked Scientists
