7:50

Circadian rhythms are one of three biological rhythms that tell the body when to eat, sleep, wake up - the biological and psychological processes that oscillate in predictable patterns each day. This internal clock is influenced by external cues, like sunlight and temperature, which help determine whether one feels energised or exhausted at differe…

The Biology Behind Beards - A Manifestation of Masculinity 10:54

7M ago10:54

10:54

In the realm of human appearance, few features carry as much symbolic weight as the beard.

The Daredevil Within - The Biology Behind Risk-Taking 16:24

7M ago16:24

16:24

There is no doubt that some individuals are much more risk averse than others, but how do we explain individual differences in risk-taking behaviour? Perhaps the answers lie in our biological differences; these can include differences in brain structure or function, as well as those caused by the process of evolution. Understanding the biological b…

Curing Dementia - Examining The Role of our Glymphatic System 13:26

1+ y ago13:26

13:26

The glymphatic system works as a waste-carrying drainage system which removes unwanted materials from the brain. It was identified as a system in 2013 by Danish neuroscientist Maiken Nedergaard. He used the term glymphatic because the system works in a similar way to the lymphatic system but it is managed by the glial cells of the brain. There are …

It wasn’t until Sperry’s split-brain research that it was possible to test the idea of hemispheric lateralisation. His studies used a unique group of participants, all of whom had undergone the same treatment for their severe epilepsy which involved cutting the corpus callosum in order to control severe epileptic seizures. While the surgery was suc…

Vasectomy and its reversal 8:47

2+ y ago8:47

8:47

Vasectomy is a safe, effective, and permanent method of birth control for men. It is also the most cost-effective form of birth control, costing half as much as a tubal ligation (having a woman's "tubes tied"). A successful vasectomy will last for life, but if circumstances change, the procedure can be reversed. In this podcast, I'll discuss how th…

Would we be wise to pay more attention to the role of our microbiome with regard to our health? 19:23

2+ y ago19:23

19:23

Microbial genes have been found to perform a variety of functions including coding for enzymes to hydrolyse food we can't digest, coding for proteins that form essential nutrients, making vitamins we can’t produce and even helping to release energy from our diet. In addition to playing a vital role in metabolism, our microbiome stimulates the immun…

How will doctors practice medicine in 2031? (with Ellie MH) 5:17

3y ago5:17

5:17

2020 proved to us all that health is unpredictable. The pandemic, not only catalysed a global crisis as services were strained and lives were lost, but also forever altered the way we practice medicine. We saw a 50% drop in A&E visits, whilst more importantly a great proportion of appointments were moved online. This shows the great adaptability an…

Killing Wildlife - Should we ever cull animals? 20:33

3y ago20:33

20:33

Culling is defined as the killing of animals in order to reduce population numbers. Culls can happen for various reasons, including health and disease control and prevention, or to protect other species. However, the ethics make the subject a strongly polarising one, and while culling in some cases may be necessary, it can be unclear when culling s…

22:31

Sometimes, scientists can take advantage of real-world incidents to help us understand the function of particular parts of the brain. Psychologists can carry out case studies on people who have experienced bran injuries. They are not interested so much in the actual injury, but what that injury can tell us about the normal functions of the brain. (…

Explanations of Near Death Experiences 13:29

3y ago13:29

13:29

There will always be elements of near death experiences (NDE's) that are difficult to explain scientifically. This is partly because researchers are entirely dependent on the reports people provide of their individual experience, which means the data is received second-hand and there is no way of verifying that the report given is accurate. Some re…

The Stanford Prison Experiment 16:05

Just one week before I recorded this podcast, the FDA, the Food and Drug Administration authorised e-cigarette products for use in the US for the first time ever, claiming that...'the benefit to adults trying to quit smoking outweighs the risk to young'. Vaping is often seen as the 'safer' alternative but research suggests that this is simply not t…

Sniffing out the Truth with Forensic Odorology 14:35

3y ago14:35

14:35

How keen is your sense of smell? Well, according to new research published in Frontiers in Psychology, people who witnessed a crime are able to identify criminals by their smell. Police line-ups normally rely on sight, but nose-witnesses can be just as reliable as eye-witnesses. It's not quite time to replace the sniffer dogs, however; the 2010 Ame…

16:22

By not being exposed to agents that stimulate our immune system in infancy, we are at greater risk of developing inflammatory responses and autoimmune diseases in later life. Some scientists vigorously reject the hypothesis, arguing that the term hygiene hypothesis was potentially dangerous. This is because it might lead people to believe that they…

Hormones and Their Influence on Emotion and Behaviour 18:08

4y ago18:08

18:08

Hormones are chemical messengers that have a specific physiological effect in the body. Research suggests that hormones also have considerable influence on behaviour and emotion in both human and non-human animals. This supports the notion that behaviour and emotion have physiological origins. It is not appropriate, however, to say that hormones ca…

There is evidence that, when the solar system was young, conditions on Mars and Venus may have been suitable for life. The surface of Mars has clearly been altered by water in the past and it may still exist deep underground. Venus is the nearest planet to Earth and is almost identical to Earth in both size and geological composition. Recent resear…

The prostate gland grows in men at puberty and secretes the fluid that carries the sperm. It remains a constant size until about the age of forty, then it begins to grow again. About 50% of men aged 60 have some enlargement of the prostate gland and this rises to 90% at the age of 80. This enlargement may be benign – effectively harmless. However, …
