Science Podcast: Dire Wolf Extinction, Pluto’s Blue Haze & Mice Empathy

DNA clues point to how dire wolves went extinct, and a round-up of the main impacts of Brexit on science.

In this episode:

00:45 Dire wolf DNA

Dire wolves were huge predators that commonly roamed across North America before disappearing around 13,000 years ago. Despite the existence of a large number of dire wolf fossils, questions remain about why this species went extinct and how they relate to other wolf species. Now, using DNA and protein analysis, researchers are getting a better understanding of what happened to these extinct predators.

13:31 Post-Brexit science

In December, a last minute trade-deal between the UK and EU clarified what the future relationship between the two regions would look like, after Brexit. We discuss the implications of this trade-deal for science funding, the movement of researchers, and data sharing.

Architecture Books: ‘Vertical Living’ (2021)

Vertical Living is an introduction to the architecture and interior masterminds using skillful, clever design to conquer compact living wherever there is space. As we continue to expect more of our flats and houses, unexpected approaches are necessary for the future of our urban spaces.

The era of moving to the suburbs is coming to an end. Instead, a growing movement of city dwellers are looking for grand architectural solutions in the smallest of spaces. Slender, slim, and tall structures are soaring in the limited land available, offering innovative solutions to a world with ever-growing urbanization.

The book looks at ingenious architectural solutions: impossibly skinny houses wedged into narrow plots, spacious homes built into neglected infill sites and comfortable homes created in tiny spaces. By combining inspirational projects, in-depth features and engaging profiles of architects around the world, Vertical Living will offer a new way of looking at how we live in the built environment.

Delivery-Only Dining: ‘How Covid Accelerated Rise Of Ghost Kitchens’

Ghost kitchens are kitchens designed for delivery-only businesses, without dine-in areas or customer facing storefronts. The pandemic has ravaged dine-in eateries, and companies that have focused on delivery could come out on top if the current trends continue. Watch the full video to see why ghost kitchens are taking over the restaurant industry.

Here are some of the top Ghost Kitchens:

Kitchen United

With a $10 million dollar investment from Google Ventures, Kitchen United has been one of the leanest (and fastest-growing) startups in the space. Founder Jim Collins has turned down hundreds of millions of investment dollars to focus on growing more organically. Currently, Kitchen United plans on conquering the global restaurant space — with 5,000 kitchens planned in the next four years.

All in all, Kitchen United offers a turn-key, light-capital model, delivering a complete, code-safe kitchen replete with appliances and cooking implements. All that’s left to do is to…cook.

CloudKitchens

The fastest-growing and most investor-friendly ghost kitchen startup, CloudKitchens, has already taken in over $400 million from investors. $150 million interestingly invested by its founder (former Uber superstar) Travis Kalanick. Like Kitchen United, CloudKitchens offers fully-equipped kitchens (branded as “smart kitchens”) for the delivery-only model. Honestly, you can’t ignore a project that Travis is a part of.

DoorDash Kitchens

Another not-so-surprising entry into the ghost kitchen space is DoorDash, which has already premiered locations in San Francisco and Redwood City. Currently, DoorDash’s model is focused on catering to high-delivery areas for established brands like Chic-Fil-A, but we’re sure they have plans in the works for new locations, as well.

For the time being, DoorDash Kitchens is still in the experimentation phase, with only a few locations. And, like others on this list, it provides everything a restauranteur would need for a single monthly fee.

UberEats

For the moment, we’ll set aside the possible conflicts associated with Uber’s ex co-founder Travis Kalanick — who’s also operating CloudKitchens. We’re sure that bridge will need crossing at some point if Uber expands its operations. For the time being, the ridesharing company has been keeping a low profile in the ghost kitchen space. To date, it has been testing ghost kitchens in a few markets, though it remains curiously reluctant to share the delicious details pertaining to its Paris operations.

Virtual Kitchen Co.

Another new entry is Virtual Kitchen Co. — which already operates several successful ghost kitchens. They plan to open 15 more kitchens over the next few years, driven by $15 million dollar Series A.  Again, Virtual Kitchen Co. offers a similar pricing structure: Restaurants can pay a monthly fee for everything.

The one small difference here is that Virtual Kitchen Co. seems to be targeting existing restaurants that want to enter the delivery space.

Travel: ‘St. John Island – Virgin Islands’ (8K Video)

VIRGIN ISLANDS 8K is a visually stunning journey through one of the most beautiful national parks in the world, Virgin Islands. Journey with More Than Just Parks as we explore this tropical paradise located on the outskirts of the Caribbean Sea. Swim with sea turtles, explore ancient jungle ruins, relax on white sand beaches, and soak in the island beauty. This is Virgin Islands National Park.

To make this film we spent weeks on the island of St John (part of the US Virgin Islands) hiking every trail in Virgin Islands National Park and swimming every bay (for good measure). We visited the park after the 2017 hurricane maria damage and were frankly quite surprised by what we saw. When you look at a lot of the photos and video online it does not represent what exists in the park today.

All of our footage represents the park in it’s current, post-hurricane, status.Filming locations included: Trunk Bay, Maho Bay, Lameshur Bay, Cinnamon Bay, Reef Bay (trail, ruins, & sugar mill), Annaberg Plantation Ruins, Ram Head, Caneel Hill Trail, Margaret Hill, Catherineberg Ruins, Honeymoon Beach, Salomon Beach, Francis Bay, Waterlemon Cay, Little Lameshur Bay, and so much more.

Ecology: Benfits Of 50% Of Serengeti Grasslands Burning Each Year (Video)

After receiving twelve hours of solar energy every day, the Serengeti grasslands become a tinderbox, just waiting to be lit.

The vast majority of the African fires currently burning seem to be in grasslands, in exactly the places we expect to see fires at this time of year. These fires are usually lit by cattle farmers as part of their traditional management of the savannahs where their animals graze. Some fires are started to stimulate new growth of nutritious grass for their animals, others are used to control the numbers of parasitic ticks or manage the growth of thorny scrub.

Without fires, many savannahs (and the animals they support) wouldn’t exist, and lighting them is a key management activity in many of the iconic protected areas of Africa. For instance the Serengeti in Tanzania is known worldwide for its safari animals and awe-inspiring wildebeest migration – and our work shows that around half of its grasslands burn each year.
