From London to Australia in 5 hours? Way cool.

A UK company, Reaction Engines, introduced exploratory plans for a hypersonic, eco-friendly passenger jet that would make it possible to fly from the UK to Australia in as little as 5 hours, reports The Guardian today. With funding from the European Space Agency, a team of engineers and scientists has come up with the A2, a plane they believe could carry 300 passengers at a top speed of more than 3,000mph.

Reaction Engines has designed an engine that would run on liquid hydrogen, rather than producing vast amounts of carbon emissions it gives off water vapor and nitrous oxide. Another advantage of the design is that while the 132 meter-long A2 is much bigger than conventional jets it would be lighter than a Boeing 747 and could land on current airport runways. There are some drawbacks, too, such as the possibility of damaging the atmosphere, because the plane would fly at around the height of the ozone layer. Also, it won’t be great for anyone who suffers from claustrophobia, as it does not have any windows.

Who needs windows if surfing in sunny Bondi Beach becomes a day trip, though?

Big in Japan: Japanese mad scientists are at it again

Disclaimer: This post is about science, which I know isn’t exactly one of the zaniest stories on Gadling at the moment. However, I can assure you in plain and simple laymen’s terms that this post will be really, really cool to read.

One of the greatest parts of living in Japan is that you’re usually the first person out of all your friends back home to get their hands on the latest electronics.

For instance, I regularly rock out touch-screen digital cameras, handheld GPS units and cell phones that make the IPhone look about as advanced as a VCR.

Indeed, high technology is a fact of life here in Japan – toilets wipe your butt for you, and ATMs thank you in a sexy voice for making a transaction.

So, it shouldn’t come as a surprise that mad scientist-inspired research regularly splashes across the headlines here in Japan.

Case in point – last week in Japan, researchers were successfully able to implant a small camera inside a mouse’s brain to see how memory is formed.

Even if you’re not a scientist, you have to admit – that is pretty awesome!

Want to know more? Sure you do…

As I said before, neurobiology isn’t exactly the easiest of disciplines to understand, so I will try to explain everything in layman’s terms. Wish me luck!

First question: why would the Japanese want to take images of a mouse’s memories?

The hope is that one day, this research will facilitate our ability to treat Parkinson’s and Alzheimer’s diseases (in humans of course!) by better understanding the brain activity that triggers these conditions.

Second question: how small of a camera do you need to film mice memories?

According the study published in the Journal of Neuroscience Methods, which I can assure you is a gripping read, the team used a camera 3 mm long, 2.3 mm wide and 2.4 mm in depth. If you don’t understand metric, trust me – that’s really small!

Third question: how do you film a mouse being nostalgic about the past.

First of all, you need to implant a camera inside the hippocampus of the mouse’s brain. Next, you need to inject the mouse with a special substance that lights up whenever there is brain activity. Then, you just sit back and wait as the camera captures the light and displays the image on a screen.

Makes sense? Hope so!

Anyway, I know science can be like, all technical and stuff, but hopefully this little foray into neurobiology wasn’t too difficult.

After all, this really is groundbreaking research that will hopefully one day result in a treatment for some of the most debilitating neurological diseases known to man.

So, at this point in the article, I have one last thing to say:

“Are you thinking what I’m thinking?”

“I think so Brain, but me and Pippi Longstocking… I mean, what would the children look like?”

(That one was for all the Animaniacs fans out there!)

Masdar, the world’s greenest city

If you had to take a guess where the greenest city in the world is going to be by 2009–and yes, I am talking green as in “zero carbon”, “zero waste”, “car free “city–where would you guess it would be?

I was completely off. I just didn’t think that a region rich in oil would be the first one to come out with a project of this scope.

The first city in the world based completely on renewable energy will be built in the United Arab Emirates. Electricity for the six-square-kilometer Masdar City will be generated by photovoltaic panels, while cooling will be provided with concentrated solar power. According to ENS newswire, design and operation of Masdar City must deal with the realities of Abu Dhabi’s sub-tropical, arid climate where temperatures range from a low of around 50° F to a high of around 118° F in the summer.

It is not the most beautiful skyline I have ever seen, but beauty might be an overrated concept in the 21st century.

Big in Japan: Deadly dumplings injure 175

One of the many things that I’ve learned about the Japanese since moving to Tokyo is that they love to eat.

Of course, unlike Americans who seem to take extreme pleasure in enormous portion sizes of incredibly fatty food, the Japanese are much more refined in their culinary choices.

Indeed, Japanese society is structured around the fine art of sharing food with friends, which is perhaps one reason why the quality of meals over here is arguably the best in the world.

So, you can imagine the havoc that is spreading through Japan this week following the news that 175 people checked themselves into the hospital after dining on deadly dumplings.

How potentially deadly where the dumplings in question?

Well, not that deadly – unless of course you consider pesticides to be an acceptable condiment!

Delicious. Nothing like a few hundred milligrams of an insect-killing chemical concoction to cleanse the palatte and settle the stomach!

Jokes aside, the case of the deadly dumplings is actually an incredibly serious matter that might possibly endanger the future of Chinese-Japanese economic and political relations!

(I told you that eating was a very serious business in Japan!)

So, let’s start off with something simple – what exactly is a dumpling?

Good question!

Dumplings in Japan are known as gyōza (餃子), and are generally comprised of some mystery blend of meat and vegetable that is wrapped into a thinly rolled and sealed piece of dough.

Gyoza are generally served with three dipping sauces – soy sauce, rice vinegar and hot chili sauce – though each gyoza aficionado generally mixes up their own special blend of the three.

Anyway, let’s get back to the story….

Two weeks ago, the Chinese government launched a fourth-month campaign to eliminate “non-food materials” from their food exports.

What exactly is a non-food material you ask? Well, simply put, anything that isn’t a food material, like industrial dyes, pesticides and fungicides.

Getting hungry yet?

Despite this pledge however, Chinese-made dumplings containing pesticides sickened 175 Japanese, which has created a huge scandal that is impossible to ignore in a society that is borderline obsessed with their personal safety.

Last year, the Chinese exported a whopping US$56.7 billion of food to Japan, though analysts are warning that this lucrative industry is about to take a huge hit.

According to Minoru Morita, a Tokyo-based economist, “Japanese consumers, already distrustful of Chinese products, may stop buying them.”

Just ask Hiroko Date, a 38-year-old mother of two in Tokyo: “It makes you scared to buy imported food — you worry about your kids.”

So, for the time being, it looks like there won’t be too many plates of dumplings gracing the dinner tables of Japan for quite some time.

With that said, if you’re reading this article somewhere across the Pacific Ocean in North America, you also probably might want to pass on any pre-packaged dumplings you might find at the local supermarket.

Sigh – looks like I might have to find another favorite drunk food, though fortunately ramen is still safe!

On my first trip to Asia I couldn’t believe how casually gas was sold there — often, someone sits at a stand on a corner with recycled 2-liter soda bottles filled with petrol. Here, LadyExpat captures a slightly-more-professional operation in Northern Thailand.
