Ask Engadget: can you use an Android tablet as a graphics tablet?

We know you've got questions, and if you're brave enough to ask the world for answers, then here's the outlet to do so. This week's Ask Engadget inquiry is from Xan, who wants Cintiq functionality without paying Cintiq prices. If you're looking to ask one of your own, drop us a line at ask [at] engadget [dawt] com.

"I'm a student and I'm considering staying on to do graphic design, and I really like the look of Wacom's Cintiq devices. Unfortunately I couldn't afford one even if I sold a kidney, so I was wondering if I could turn an Android tablet into a cheaper version? I figure a device like the Galaxy Note 10.1 with its Wacom digitizer would be a good fit, so is there a way to do it? Thanks!"

We're sucking in air through our teeth, as we're sorry to say, we can't think of a way this could be done successfully. There's a few problems like no software, a lack of bandwidth and doubts over the accuracy of a tablet to replicate such a sophisticated piece of hardware. That said, perhaps the forthcoming Surface Pro software update might solve this problem altogether, but an Android tablet? We're not so sure. But if there's anyone out there who has made it happen and wants to share their revelation, why not leave a note below?

Crazy ants vs. Fire ants: Who's winning? (+video)

Crazy ants are taking over areas once occupied by fire ants in the South. The sting of Crazy ants isn't as painful and migrate slowly. But Crazy ants multiply faster.

By Douglas Main,?LiveScience / May 18, 2013

Invasive fire ants have been a thorn in the sides of Southerners for years. But another invasive species, the so-called "crazy" ant ? that many describe as being worse ? has arrived and is displacing fire ants in several places.

"When you talk to folks who live in the invaded areas, they tell you they want their fire ants back," said Edward LeBrun, a researcher at the University of Texas at Austin, in a statement from the school. "Fire ants are in many ways very polite. They live in your yard. They form mounds and stay there, and they only interact with you if you step on their mound."

A study published in the April issue of the journal Biological Invasions found that in areas infested with crazy ants, few to no fire ants were present. Exactly how they are able to outcompete fire ants is so far unknown. In areas with crazy ants, the researchers also found greatly diminished numbers of native ant species, according to the study.

Fire ants are known for their painful stings and have spread through the Southeast since arriving from South America in the 1930s. Crazy ants were first discovered in Houston in 2002, and they have already spread to coastal areas from Texas to Florida, according to the researchers. Although the "crazies" don't have as painful a sting as fire ants, they multiply in even greater numbers. They are also difficult to control since they don't eat the same poison baits as fire ants do, the statement noted.

Last year, the crazy ant species was identified as Nylanderia fulva, which hails from northern Argentina and southern Brazil, according to a 2012 study in PLOS ONE. It's also known as the tawny crazy ant and was previously named the Rasberry crazy ant after the exterminator Tom Rasberry, who first discovered it. The "crazy" moniker comes from the ant's quick, seemingly random movements.

Luckily, the crazy ant doesn't spread as quickly as the fire ant, advancing only 650 feet (200 meters) per year on its own, the release noted. Therefore, it's vital that people don't accidentally transport the ant, the prime method by which it has spread, according to the release.

Ex-Pa. officer once hailed as hero faces charges

PHILADELPHIA (AP) ? A former Philadelphia police officer once hailed as a hero and given a seat next to the first lady at a speech by President Obama has been arrested and charged with rape and other crimes.

Authorities allege that former officer Richard DeCoatsworth left a party with two females early Thursday and took them to another location, where they allege that he produced a handgun and "forced the two females to engage in the use of narcotics and sexual acts."

A police spokeswoman said the two called police after he left, and 27-year-old DeCoatsworth was charged with rape, sexual assault, terroristic threats and related offenses.

DeCoatsworth was hailed as a hero after he was shot in the face during a traffic stop in September 2007 but still managed to chase after his attacker, who was later sentenced to 36 to 72 years in prison.

DeCoatsworth was invited by Vice President Joe Biden to attend the president's televised February 2009 address to Congress and sat with first lady Michelle Obama. He said he didn't know why he had been singled out, but being in the presence of the nation's leaders was an honor "that I will keep with me for the rest of my life."

WCAU-TV, which first reported his arrest, said DeCoatsworth retired from the department on disability in December 2011.

Police said no other information on the alleged attack would be released Saturday to protect the victims and the integrity of the ongoing investigation. Authorities declined to say give even general locations for the party and alleged crime scene and also wouldn't say when DeCoatsworth was arrested.

A listed number for DeCoatsworth has been disconnected and it was unclear whether he had an attorney.

Police Commissioner Charles Ramsey told a Philadelphia Daily News columnist in February of last year that he believed he had made a mistake in granting the former officer's request to go back to work too soon after he was shot.

"God bless him for still wanting to get out there and do police work, but did I act in his best interest? In hindsight, I would say probably not," Ramsey told columnist Sty Bykofsky.

Arcade Alarm Clock: The Konami Code Won't Buy You More Shuteye

It might have given you invincibility or unlimited ammo on the countless games that acknowledged it, but sadly the Konami code won't buy you a single second of extra sleep on this custom Xronos alarm clock. But the large scoreboard-like LED display and use of authentic console buttons will have you wondering if you fell asleep at the arcade again.

Obtaining polymers with ? la carte optical and electrical properties

May 15, 2013 ? By adding semiconducting nanoparticles to polymers, the Materials + Technologies Research Group (GMT) of the Polytechnical College of San Sebastian of the UPV/EHU-University of the Basque Country has created nanostructured composite materials with specific optical and electrical properties that vary according to size. These properties allow researchers to synthesise particles of the size corresponding to the desired properties, and by adding these particles to polymers, to give the final product one specific property or another.

At the UPV/EHU's Polytechnical College of San Sebastian they are working with particles that act like quantum dots, specifically with cadmium and selenium composite nanoparticles. One of the characteristics of quantum dots is that the optical and electrical properties of the particle vary according to size.

In the case of the cadmium and selenium composite particles, this variation takes place in nanoparticles of less than 10 nanometres -- a nanometre is equal to one millionth of a millimetre -- , and, "therefore it is not the same to have a nanoparticle of 3 nanometres or one of 6 nanometres," explains Haritz Etxeberria, researcher in the UPV/EHU's department of Chemical Engineering and the Environment and author of the research. This allows nanoparticles with very specific properties to be synthesised, and subsequently when these nanoparticles are incorporated into other materials, the researcher can prepare new composite materials with pre-selected properties. "Through nanocharges it is possible to add other properties to the intrinsic properties of the basic materials: nanoparticles, nanoclays, fibres, etc. Finally, by uniting the properties of some of them, materials with new properties are obtained," says Etxeberria.

In opto-electronics, biomedicine and in the field of solar panels the authors are seeking applications for the particles that function like quantum dots.

The work done by Etxeberria consisted of synthesising composite cadmium and selenium nanoparticles, and subsequently, of analysing methods for inserting these nanoparticles into a polymer. The main challenge tends to be in fact dispersing the nanoparticles properly throughout the polymer; failure to achieve this means that the composite material will not have the properties that one wants to give it by means of the nanoparticles. "Because the nanoparticles are so small, they tend to group together. So large agglomerates are obtained and they appear mixed in different phases. But when their size is increased, they lose the properties they have as nanoparticles," stresses Etxeberria.

In the first phase of the research work, Etxeberria synthesized nanoparticles of cadmium selenide of different sizes and, bearing in mind the importance of size in the properties of the particle, he analysed various synthesis parameters to optimize the synthesis of the nanoparticles and obtain nanoparticles of cadmium selenide of the desired size and properties.

In the second phase, he analysed methodologies for inserting and dispersing nanoparticles of a specific size (of between 3 and 4 nanometres) throughout the polymer. For this purpose he worked with a block copolymer made of polystyrene and polybutadiene. "We used block copolymers because they allow the phases to be obtained. They share immiscible ingredients, but because they are bonded to each other, they create phase arrangements on a nanometric level, and allow the adding of nanoparticles that have an affinity with one phase or another," explains Etxeberria.

Etxeberria was aiming to disperse the cadmium selenide nanoparticles in the polystyrene phase. To do this, he tried out various functionalization techniques. Functionalization means that molecules that will render the nanoparticles miscible in the selected phase are added to their surface so that they can be properly dispersed throughout the polymer. The best results were obtained by means of the technique known as "grafting through." "Using the grafting through technique, the nanoparticles are placed in the environment in which styrene polymerization takes place. That way, the polymer sometimes grows from the nanoparticle surface, other particles are trapped between the polymer chains, and free polymer is also created," explains Etxeberria. The result is a material that has an affinity with polystyrene, and which produces the desired homogenous dispersion when blended with the block copolymer.

This has been demonstrated by the measurements carried out on the composite material created: the composite material has the same optical and electrical characteristics that the nanoparticles had initially. In view of the good results of the technique, Etxeberria is now working on other materials, like cellulose.

BlackBerry Messenger announced for Android!

Android Central

Today at BlackBerry Live 2013, the quintessential BlackBerry Messenger was announced as coming to Android this summer! It's going to be totally free, which is a welcome surprise.

CEO Thorsten Heins announced his company's goal to make BBM the standard in cross-platform messaging and that they'll be bringing their long-standing device-exclusive service to iOS and Android. In the long run, they intend to include advanced features like groups, screen sharing, and the recently-announced Channels to the other platforms. Keep an eye out for this one in Google Play over the next couple of months, and expect it to displace a lot of the current messaging platforms out there.

Any of you guys know folks that still use BBM? Any ex-BlackBerry-owners that miss BBM?
