Zoology: The Evolution Of Seahorses (Video)
Sea horses are amazing animals because of many of their strange features like male pregnancy but also due to their beautifully unique body shape. However, this may be the reason why seahorses are famous but it actually makes them very bad swimmers so why did they evolve to have this unique body shape?
A seahorse is any of 46 species of small marine fish in the genus Hippocampus. “Hippocampus” comes from the Ancient Greek hippókampos, itself from híppos meaning “horse” and kámpos meaning “sea monster”.
Ocean Science: Can Kelp Forests Survive Climate Change, Trawler Fishing
Kelp locks up millions of tonnes of carbon globally, provides a nursery for fish and is a buffer against coastal flooding. But climate change, weather and fishing are taking their toll. Now, Mika Peck and his team at the University of Sussex are monitoring kelp off the south coast of the UK, to see if it can recover from the damage done to it by trawling and help improve biodiversity in the area.

Science: Gun Violence Research Returns, Pikas In Winter & Glass Sponges
Funding for gun violence research in the US returns after a 20-year federal hiatus, and the glass sponges that can manipulate ocean currents.
In this episode:
00:45 Gun violence research is rebooted
For 20 years there has been no federally-funded research on gun violence in the US. In 2019, $25 million a year was allocated for this work. We speak to some of the researchers that are using these funds, and the questions they are trying to answer about gun violence.

11:40 How a sea sponge controls ocean currents
Venus’ flower baskets are marine sponges that live at the bottom of the Pacific Ocean. These sponges have an unusual glass skeleton that helps them gather food, and even appears to control ocean currents.

Research: ‘The Science Of Healthy Aging’ (Scripps)
Although growing older comes with a number of major life changes, science can help inform the things we do in the here in and now to forestall the most serious features of the aging self, promoting healthspan and not just lifespan.

- Build Muscle – Muscle mass is one the best predictors of health and longevity. Muscle tissue is known to release its own chemicals called myokines, which can have benefits that span cognition, immunity and anti-cancer activity. By performing regular, resistance-based exercise that prioritizes strength, we can delay the loss of bone density and risk of physical injuries.
- Vitamin D – Commonly known as the sunshine vitamin, vitamin D is in fact a critical hormone that helps maintain healthy bones, boost our immune system and improve our cardiovascular function. With age, the production of vitamin D in the skin can become less efficient, so if we don’t spend enough time outdoors, our risk of vitamin D deficiency may increase.
- Neurodegenerative Diseases – One of the most unsettling aspects of aging is the potential for neurodegenerative disease. These conditions are increasingly prevalent in those with diabetes, suggesting that the brain’s blood flow and energy supply may be compromised. Research indicates that regular physical exercise, a healthy whole foods diet and staying intellectually active could at least slow the rate of decline.
- Mindfulness – As we get older, major arteries can become thicker and less flexible, leading to increased blood pressure and undue strain on the heart. A regular mindfulness practice such as yoga or meditation has been shown to stem the release of stress hormones like cortisol and adrenaline. By freeing us from this “fight-or-flight” state, this habit can improve blood flow and reduce the risk of heart attack and stroke.
- Stay Social – As social animals, maintaining a strong sense of community and close personal relationships into old age are underestimated contributors to longevity. While social isolation in seniors can result in significant physical and mental decline, research suggests that close loved ones offer important emotional support and behavioral modifications that can overcome periods of high stress.
- Metabolism – “My metabolism is slowing down!” That’s what we often hear, as the aging body becomes less effective at using energy, placing us at risk of obesity and type 2 diabetes. By maintaining our muscle mass and reducing sugar consumption, we can support hormonal health, preserve our metabolism and keep our vitality into those advanced years. As scientists continue to find ways to extend our lives, paying attention to these keys to healthy aging can help increase the quality of those extra years.
Science: Standard Model Of Physics, Explained
The Standard Model of particle physics is the most successful scientific theory of all time. It describes how everything in the universe is made of 12 different types of matter particles, interacting with 3 forces, all bound together by a rather special particle called the Higgs boson. It’s the pinnacle of 400 years of science, and gives the correct answer to hundreds of thousands of experiments. In this explainer, Cambridge physicist David Tong creates the model, piece by piece, to provide some intuition for how all of the parts fit together to create the fundamental building blocks of our universe. At the end of the video, he also points out what’s missing from the model, and what work is left to do in order to complete the Theory of Everything.
Science: Race-Based Medicine, Space Tourism & Western U.S. Heatwave
Race-based medical practises are being challenged more and more, as it becomes increasingly clear they have little basis in science.
The team finds out why adjustments for race and ethnicity are still being made in medicine, despite the potential harm and healthcare implications they cause. It’s been a massive week for the future of space tourism – the team shares a clip of a very excited Richard Branson who’s recent journey into microgravity has set the stage for the launch of Virgin Galactic’s first commercial space flights. The team gives an update on the dramatic heatwave ravaging the US, as more record high temperatures are set, continuing to leave destruction in its wake. They also explain what ‘impact gardening’ is and why it might help us find alien life on Jupiter’s moon Europa, and they share important news on the state of the cosmetics industry in Neolithic times. On the pod are Rowan Hooper, Chelsea Whyte, and Layal Liverpool.
