Western Drought: Expect More Fires & Water Wars

As of mid-June, nearly three-quarters of the US’s West has been experiencing “severe,” “extreme,” or “exceptional” drought conditions. In addition to the states above, it also includes northern states like North Dakota and Montana.

Overall, climate change is playing a role. But there are smaller factors at play that are tied to climate change as well. Including…

  • Not enough rain. The National Oceanic and Atmospheric Association (NOAA) said the Southwest’s 2020 monsoon season (read: ‘nonsoon’) was “the hottest and driest summer/monsoon season on record.” And the decrease in rainfall is having an impact on today’s drought (think: not enough water for crops, lakes, or reservoirs). And for the little rain that has fallen, it could dry up faster because of…
  • Warmer temps. The NOAA dubbed 2020 the second-hottest year on record. And in late June, a record-breaking heat wave hit the Pacific Northwest, with the temperature reaching up to 112 degrees Fahrenheit in places like Portland, OR. (Psst…if you’re dealing with hot weather, here are some tips to stay safe.) Hotter, drier weather creates a thirsty environment, which speeds up evaporation. Rising temps are also causing snowpacks to melt faster, and they’re reportedly producing less runoff – a vital water resource. All of which means there’s less water available for communities and ecosystems.

Experts are also worried that the current dry and hot conditions will have a ripple effect, which brings us to wildfires. Last year’s West Coast wildfire season was the worst ever. Fires in California killed 31 people, burned more than 4 million acres, and destroyed thousands of buildings and structures. And this year, states like Arizona have seen an early start to their wildfire season. But the effects of the drought stretch even further.

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.

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.

Summer 2021
  • 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.
