Testing your blood might be a troublesome process, especially if you’re in countries that aren’t that well developed. It seems that Harvard chemist, George Whitesides, might have come up with a simple solution on how to tackle this issue, and it just costs a cent. This little square of paper contains comic book ink, which is water-resistant, and will push the blood dropped on it into different paper channels, each of which contains chemicals that react with the blood, and will change color to indicate if the blood contains a certain type of disease. With a low production cost, and the simplicity of its use, it certainly seems like a viable option. Video after the jump. Permalink: Low Cost …

Point : As my fellow Jalopnik readers would agree, the thought of an au-to-MO-bile running on some coffee beans is equally laughable and insulting. Counterpoint : As my fellow coffee drinkers would agree, this is an utter disgrace to our holy bean. Countercounterpoint : Carpuccino? Really? A while ago we read that coffee-based biofuels were feasible. Knowing the internet as we do, we figured it was only a matter of time before somebody took that novel possibility and turned it into an absurd reality. We were right! The Carpuccino, a 1988 Volkswagen Scirocco modified to run on ground coffee, will drive 210 miles between Manchester and London in the coming weeks. The trip will require over 150 pounds of coffee, with the car …

AT&T is late to the Android games, but they’re making up for lost time with five Android handsets in the first half of the year. First up: the Motorola Backflip , coming March 7th for $100 with contract. Wait… $100? To me that seems a little steep, but I guess that’s because I’m not the biggest fan of Motoblur, Motorola’s social UI. The Backflip also has a touch panel on the back, though that doesn’t function as anything more than a D-pad, along with a 3.1-inch hi-res screen and a 5MP camera (with flash) on board. It’s also compatible with AT&T’s speedier 7.2 HSPA 3G network. Most importantly: if you’ve been stuck in an AT&T contract and worrying that the Android grass is greener, you’ve …

President Barack Obama’s $8.3 billion in loan guarantees for new nuclear power plants announced earlier this morning is aimed squarely at building more of the massive, gigawatt-sized reactors we’re all familiar with. Big nuclear is also the target for $36 billion in loan guarantees that the Obama Adminsitration has proposed for the Department of Energy’s 2011 budget. Still, that same budget request could represent opportunity for the handful of startups venturing into the world of nuclear power, if they can deliver on promises of small-scale, modular reactors, nuclear technologies that fuel themselves, or the long-awaited working model of a fusion power plant. Take small-scale nuclear plants, which are the target of some $38.8 million…

Are you a huge nerd? No? Sorry, I guess that solar backpack you’re wearing kind of threw me off. Looks like Playskool meets Transmetropolitan. Not exactly a babe magnet. I’m going to let you in on a secret, big guy: check out these Soular Power bags from Neon Green. If you absolutely must wear a solar panel backpack, it might as well be the coolest one out there, right? That’s a bit like being the thinnest kid at fat camp, but… what? No, I’m not implying anything. Yeah, well, I’ll keep my good advice to myself from now on! Nyah! Get outta here! Ahem. These backpacks do look pretty cool. Well, a couple of them do anyway. Mainly that white…

AMEE , the US/UK-based startup that aims to build the largest engine for computing greenhouse gas emissions, has secured a $5.5m series B financing lead by Amadeus Capital Partners alongside existing investors, including O’Reilly AlphaTech Ventures and Union Square Ventures. AMEE will use the funding to expand its geographic reach and platform. The prize AMEE is aiming for, known in the sector as “enterprise carbon management”, is expected to reach $4 billion by 2017 because of government and consumer pressure to address climate change. AMEE’s engine is now being used by companies offering carbon accounting or business intelligence software, as well as governments, multi-nationals and SMEs.

Tesla Motors, the San Carlos, Calif.-based electric car startup, has just registered with the Securities and Exchange Commission for a $100 million initial public offering. This could be the biggest and possibly the first public offering for a U.S. car company since Ford Motor’s IPO more than 50 years ago. The long-awaited IPO (rumors swirled last fall that the filing could come any day and the startup has discussed for years its intention to go public), if and when it goes through, will offer a test for whether the classic venture capital model (invest early and find a big exit in the form of an acquisition or an IPO) will be viable in the nascent green car…

This seems like a really good idea. A German company called Armatix has developed a handgun that can only be fired by someone wearing a biometrically unlocked wrist watch. An LED light on the gun glows green if it’s set to be fired or red if it’s locked. According to the product page: “To activate the wrist watch, the authorized person’s fingerprint must first be read by the wrist watch. An internal database compares the current fingerprint against stored prints and responds accordingly. The wrist watch is then activated for a definable period – e.g. an officer’s work shift or until manually deactivated.” So probably not great for cases when you need to fire as quickly as possible (unless whatever’s…

If you’re on terra firma, it’s pretty obvious when you need to grab your make-out partner. But how, Slate’s Explainer asks, do you know when to celebrate “when you’re hurtling through time zones at 17,500 miles per hour?” The obvious answer is something like: “you don’t pick a single moment, you celebrate once over each of the 30 different time zones in an all-day, ISS, kegger of space beer blow out. The actual answer is a little less exciting. The ISS astronauts set their clocks to Coordinated Universal Time, which is the same thing as Greenwich Mean Time, just with a cooler name. That means they were debating …

Would you want to be bathing in a LED light shower in the future? The idea from Visentin is a luxury shower head that bathes you in a rainbow of therapeutic colored LED lights such as orange, renewing white, relaxing blue, healing pink or refreshing green, each with its own therapeutic qualities, turning your shower into some sort of a home spa. It certainly looks futuristic, and who knows, maybe we’ll all be using this sometime in the future, right? Permalink: Visentin LED Light Shower from Ubergizmo | Hot: Blackberry Bold 9700 Review
