Can stem cell research save endangered species?

by Sean McLachlan on

New advances in stem cell research are giving hope in the fight to save endangered species.

Scientists have created stem cells for two endangered African species–the northern white rhino and the drill monkey. They “reprogrammed” skin cells to make them revert to stem cells, an early stage of cell development in which a cell can develop into different types of specialized cells.

It’s hoped that one day these stem cells could be made into sperm and eggs, leading to test tube babies that could bolster dwindling populations of some species. This has already been achieved with laboratory mice.

The white rhino used to be a favorite of safari goers and, unfortunately, big game hunters. There are probably none left in the wild, and only seven in captivity. These rhinos are the poster children of how tourism can hurt the environment.

This stem cell breakthrough is good news. With Obama scrapping tighter smog regulations and China discovering just how much they’ve screwed up their environment, we can’t rely on our so-called leaders to get us out of this mess. While environmentalists say we all need to change our attitudes in order to save the planet, that’s unlikely to happen. In fact, science is the only part of society that regularly advances. Common sense, foresight, and wisdom sure don’t.

Here’s hoping the scientists can give us a world where our children don’t have to go to a zoo to see wildlife.

Dog found at summit of Kilimanjaro

by Kraig Becker on

Four climbers on Tanzania‘s Mt. Kilimanjaro had a surprise waiting for them when they arrived at the summit of Africa‘s tallest mountain last week. After making the long, and sometimes arduous, trek to the top, they were surprised to find a dog had arrived before them.

Antoine le Galloudec, Kristina Meese, Irina Manoliv and Monique Indino were climbing with a local tour company, when they approached the top of the mountain, known as Uhuru Peak. Galloudec said that he needed to heed the call of nature and stepped off to the side of the trail to take care of business. He was shocked to find the dog lying on a rock no more than a meter away.

The group was careful not to disturb the adventurous pooch, choosing to instead snap a couple of photos using a cell phone. When they later showed those photos to one of their guides, he told them that the same dog had been spotted at one of Kili’s lower camps ten years ago. Why the dog is still on the mountain, and how it has survived so long, remains a mystery.

High winds and cold temperatures are a common occurrence on Kilimanjaro, although it is the thin air that is usually the most difficult condition for people, and animals, to adapt to. If this really is the same dog that was spotted on the mountain a decade ago, he has probably become quite acclimated to life at altitude. Finding food is most likely a bigger challenge, although while I was there a few years back, there were plenty of small rodents, even high up, and I’m guessing the dog could find scraps left behind at some of the camps as well.

Climbing Kilimanjaro is one of the top treks in the world, and while there are no technical requirements for completing the climb, it is physical demanding to say the least. The hike to the summit generally takes about 5-6 days, and the view of the surrounding landscape is spectacular, however. I’d recommend the climb to anyone looking for a challenging adventure, but be sure to cap the experience with a Serengeti safari afterwards.

Travel writing: how not to do it

by Sean McLachlan on

We’ve had some interesting posts on travel writing lately, including Don George’s secret formula for writing a successful travel narrative and Pam Mandel’s report on Book Passage. While studying good writing is vital to learning how to write, it’s also important to study bad writing so you know what not to do.

Talented writer Steve Almond tackles this for us with his hilarious skewering of Toto’s 1982 pop hit Africa. I never liked this song, although it was the background theme to far too many high school memories. While this is a song and not a travel article, it includes many of the mistakes sloppy writers make when covering travel in general and Africa in particular. Watch, laugh, and learn.

Thanks to my friend Hannah for showing me this vid!

Tanzania Game Reserve at Risk

by Pam Mandel on

First, a highway through the Serengeti, now, a uranium mine in Selous Game Reserve. Tanzania’s plans are drawing the ire of environmentalists, conservationists, and zebra-and-wildebeest huggers around the world. The government is eying Tanzanian game and park lands for developments that are in direct conflict with migrating wildlife, potentially risking their only sustainable economic sector: tourism. From an eTurbo News article:

Tourism is potentially the most important sustainable economic sector for Tanzania. We can make more money over a longer term, and create more jobs, earn more forex, and introduce more investment than mining Uranium in the Selous. The mine might last maybe 25 or 30 years, and the environmental damage will be huge. Once the resource has been plundered, I have really no other description, it will be the same like with our gold deposits. The ‘investors’ will move on and leave us with giant holes in the ground and massive destruction.

The Selous Game Reserve is home to elephants, black rhinos, giraffes, hippos, crocodiles and hundreds of bird species. It’s a UNESCO World Heritage site occupying over 20,000 square miles of Tanzanian savanna. Access to the reserve is supposedly tightly managed — there are no permanent structures human habitation allowed — but poaching is still a problem. And there are those valuable minerals in the ground, tempting short term exploration and exploitation with potentially permanent long term consequences. From the UNESCO listing for the Selous Game Reserve:

The most significant threats are related to exploration and extraction of minerals, oil and gas, and large infrastructure plans; environmental impact assessments need to be conducted for all development activities in the vicinity of the property that are likely to have an impact of the property’s Outstanding Universal Value.

A BBC report says that the government is determined to push the uranium mining project though in spite of objections. From the BBC:

…the uranium mining project was in its infancy, but it would only affect about 0.69% of the current World Heritage site park and would be an important source of income for the country

Firms could expect to earn $200m (£125m) each year from mining uranium from the site, of which $5m would be paid to the government…

It’s unclear if the profit is worth the potential long term damage.

New National Geographic app puts the world in your hands

by Kraig Becker on

If you’re a fan of maps, then you’re definitely going to want the latest iPad app from Nat Geo. The new app, entitled The World by National Geographic, provides an interactive atlas that lets you explore the planet from your easy chair, while giving you multiple zoom levels, country facts, and wonderful photos from a variety of locations.

When you launch the app for the first time, you’ll be presented with a view of the Earth from space. If you’re anything like me, your first instinct will be to spin that globe, just like you would a physical one that exists in the real world. I was delighted to find that swiping a finger across this virtual representation of the planet did just that, with the animation running very smoothly. The usual array of iOS gestures work as well, and soon you’ll find yourself intuitively pinching to zoom, tapping on points of interest, and so on.

At the start, you’ll be able to easily identify the seven continents, with red lines clearly marking the borders between countries as well. You’ll also notice a number of yellow dots sprinkled across the globe that indicate that more detailed maps are available for that region. Some of those dots will be labeled, while others won’t indicate the area they represent until you tap on them. Double tapping will zoom the view in much closer, presenting a higher resolution version of that region that offers far more detail, including individual towns and villages, roads, rivers, and much more.

Along the bottom of the screen you’ll find alternative ways of navigating the app, including a “Maps” section that shows all of the individual regional maps that are available in the software. You can also search for countries by name or continent, which will show an alphabetical listing of those nations along with a graphical representation of their flag. In this mode, when you tap on the country you wish to find, the globe will automatically spin to that destination, while simultaneously zooming in to a more detailed level. You’ll also be presented with a number of facts about the country as well with such data as population, capital, currency, and much more placed at your finger tips.As you might expect, the “Photos” option presents a number of beautiful images from a number of countries, which are once again listed in alphabetical order. Tapping on an image displays a larger, higher resolution version and includes a caption to let you know exactly what the photo is and where it was taken. While you can spend a couple of hours flipping through the photos, I would have liked to have seen even more. As a fan of National Geographic’s trademark photography, I felt the offerings were sparse at times, with many countries having just one photo or none at all.

I’ve always been someone who has been fascinated with maps and atlases, so I found myself thoroughly enjoying The World, but if you’re not a map fiend, you may find yourself growing bored rather quickly. You’ll also discover that without an Internet connection, some of the higher resolution version of the maps won’t be available to you. That said however, this app isn’t designed to be a navigational aid, but more of a reference. In other words, you won’t be heading out on your travels intending to use this for finding your way around. Instead, you’ll curl up with it on the couch when the need to explore comes over you, but you just don’t feel like heading out the door.

The World is available now in the App Store for $3.99 and is yet another high quality app from National Geographic, who has put out a steady stream of them over the past year or so. Unlike most of their apps however, this one is only available for the iPad and won’t run on the iPhone or iPod Touch.
