Need Electrical Juice? Walk More!

August 14, 2023 by noemi

How often do you have to charge your smartphone? I think I mentioned some time ago that ever since I switched to the iPhone 4, I have had to charge my mobile phone every day. Comparing this to the every other day (sometimes every three days) charging I had to do with my Nokia E63, it does seem excessive. However, if you think about what one normally does with the iPhone (not to mention 3G or Wi-Fi always on), the once a day charging system does make sense.

Having access to electrical juice is something that the modern person has to deal with on a daily basis. As such, researchers are also on the ball as to figuring out how to make batteries last longer and how to provide consumers with more power. [Read more…] about Need Electrical Juice? Walk More!

New Discovery: Birds Tweet Using Grammar

August 3, 2023 by noemi

Finches follow grammar rules when tweeting

That’s more than you can say for many of their human counterparts who tweet in the technological way, yes? 😉

All kidding aside, scientists have found signs that those cute little creatures with feathers have something that resembles grammar as we know. Based on a report published by New Scientist ((Source)), Bengal finches have their own syntax when they chirp, sing, tweet, or whatever you want to call it. While the birds do not have the same concepts that we humans (such as the parts of speech – nouns, pronouns, verbs, adjectives, adverbs, etc.), they have syntactic structures.

By the way, syntax is defined as the ” is the study of the principles and rules for constructing sentences in natural languages.” ((Wikipedia)) Basically, the birds having a syntax of their own means that they have rules that govern their “speech”. Grammar falls under syntax.

I suppose that this is not a totally new concept and that, in fact, many people have suspected this for the longest time. The breakthrough is that researchers from Kyoto University in Japan have actually found some proof that this suspicion might be true. What the scientists did was to play various songs until the finches got used to them – or understood them. They then jumbled up the syllables in the songs and observed how the finches reacted. What they found out was that only one of the four jumbled up songs made the finches react in an adverse manner. The scientists say that based on the finches’ reactions, it seemed that the particular song broke the birds’ grammar rules – whatever those rules may be. And if you are thinking if it was just coincidence, give the researchers a little more credit, will you? They did the experiment on many birds and they had the same reaction – at least those birds who were exposed to other birds.

That last bit seems to support the idea that the grammar rules are not innate in the finches. They have to learn the rules – just like we humans do.

I don’t know about you, but I find the study – and its results – fascinating. Maybe these birds can teach humans to follow grammar rules a little more on Twitter. You know what I’m saying?

Learn How to Play an Instrument with PossessedHand

August 3, 2023 by noemi

Do you love music with a passion but unfortunately music does not seem to love you back all that much? There are countless people who would give an arm and a leg to be able to play the guitar like Jimi Hendrix, Stevie Ray Vaughn, Joe Satriani, Steve Vai, and the rest of the guitar legends. Others would love it dearly to be able to play the piano. Whatever instrument it is that you dream about, there just might be hope for you.

If this new technology succeeds, then maybe children will not have to be forced to go to piano lessons after school while their classmates played outside. (Yes, there is some regret in that statement, but I wish I had paid more attention to those lessons and actually practiced the piano in my spare time as a kids!)

Researchers in Japan have come up with a device that is supposed to teach people how to play a musical instrument by taking control of the hands. Yes, you read that right. Dubbed PossessedHand, the device works by taking over the user’s hands, and in the process, teach the person how to play a specific instrument. In spite of the name, the device does not involve spirits or possession, which I suppose many people might appreciate.

The project is a joint endeavor by the University of Tokyo, Japan, and Sony Computer Science Laboratories. With those two entities involved, I am already convinced. My brain is screaming, just give me the device already! I am daydreaming about playing the piano on a stage somewhere in Tuscany while Andrea Bocelli sings to my music…

Back to reality, though, the PossessedHand works by stimulating the muscles in the forearms with electricity. These muscles are the ones responsible for moving our fingers. So if you were to wear the device, your hand would look something like this.

If you think that is a little freaky, then get ready for this: your hands will move on their own, without your brain telling them to. That’s how the electric impulses work – they control your fingers so that you can play a musical instrument even if your brain doesn’t understand how to. Can you imagine just how freaky that would be? Parts of your body moving without you controlling them.

As of now, the device is meant to help budding musicians learn (faster?). It is also meant to help those in need of rehabilitation. All I can say is that freakish or not, this device would be a welcome thing to play with. I do have this feeling that no device can replace musical talent, though. Still, a girl can try, can’t she?

Let Your Fingers Do the Charging: Possible “Everlasting” Battery

August 2, 2023 by noemi

If this new technology fully becomes reality, you might have no issues with your phone’s battery life anymore. Researchers at RMIT University in Melbourne, Australia have found a way to generate electricity in a manner that suits every touchscreen user’s habits – by applying mechanical pressure to piezoelectric thin films.

Think about your iPad (or Samsung Galaxy for that matter). Think about your iPhone or iPod Touch (or any other touchscreen device). Now think about how long the battery lasts. Depending on your usage and how “old” the gadget is, you probably have to charge your device every day.

Now imagine this scenario. The more your type or touch the screen of your device, the less need for charging it. I don’t know about you, but it is brilliant! No more having to lug around a cable just to make sure you don’t run out of juice while you’re on the go. No more worrying if you’re going to have enough power to last all night. All you need to do is keep on typing…

The science behind the idea I can’t spell out for you, but Dr. Madhu Bhaskaran – the lead co-author of the research – says “the research combined the potential of piezoelectrics – materials capable of converting pressure into electrical energy – and the cornerstone of microchip manufacturing, thin film technology.” He further explains that this concept has been proven and shown, although there remains the problem of implementation in the real world. ((Source: Physorg))

No doubt that the team – or some other guys – will be able to rise to the challenge of actually using this technology to benefit the countless technophiles all over the world. As for those who keep fiddling with their phones, you’ll finally have the excuse to keep on typing – you need more juice!

Hemoglobin in 3D

July 28, 2023 by noemi

Were you always caught up in your biology classes way back when? I remember loving my high school biology class from the get go, only to be thoroughly turned off when the time came for dissecting a frog. I found out – the hard way – that I was not cut out to do anything remotely related to touching/cutting up squishy living things.

Then again, that experience has not totally turned me off molecules and other things that can be rendered on a computer – like this hemoglobin rendition in 3D. Hemoglobin is that “thing” that transports oxygen in our blood. I can’t stand blood, but I can dig hemoglobin. 😉

So these guys from Steffen VFX, a 3D animation studio based in Brooklyn, decided to play around with human hemoglobin – its structure at least – and came up with a 3D model. They worked on this project in tandem with McFarlane Toys.

Now if you think about it, hemoglobin is so minuscule that we can’t see it with the naked eye. That’s where these guys had to do some hard work. From this structure: ((Source: Wikipedia))

They came up with this model which the average person can see and touch: ((Source: Steffen VFX))

Here’s a closer look at the 3D model.

The entire process is detailed in the Steffen VFX blog, if you are interested in the nitty gritty. You will also see photos of the making of the model. The details are a little too intense for me, but the finished product is somewhat of a delight to see, even though it somehow reminds me of fish eggs! 😉 The next time I think about blood and oxygen, I am sure my imagination will pull these images up.

HBOC201: “Unreal” Blood That Can Save Lives

July 25, 2023 by noemi

HBOC201. It may remind you of the ubiquitous TV channel, but it has nothing at all to do with that. This is the name of a synthetic blood substitute that has saved an Australian woman’s life. Tamara Coakley had a really bad car accident and was barely alive when she got to the hospital. She had only one liter of blood left in her body, and immediately needed a blood transfusion. Not to mention all the other complications, she is also a Jehovah’s Witness, meaning she couldn’t undergo blood transfusion. Technically though, using the synthetic blood is not blood transfusion as it is considered a blood substitute. ((I honestly am hard pressed to see the difference, but okay.))

In any case, HBOC201 is something that probably belongs to science fiction. This blood substitute contains a molecule that is derived from cow plasma. It was developed by the US Navy and can be used for a wide variety of conditions wherein a blood transfusion is required.

It may not seem an appealing choice, given that HBOC201 is essentially made of cow plasma. Then again, we already drink cow’s milk. This isn’t much different, is it? This blood substitute presents a lot of potential. For one, HBOC201 is not limited by blood type restrictions. Whatever your blood type may be, you will be able to receive HBOC201. Another thing is that HBOC201 is stored more easily. It can be kept without refrigeration for up to three years. This can mean a lot for those in areas where electricity is not taken for granted! And with the low supply of donor blood, HBOC201 just might be what is needed to save other people’s lives.

Science fiction? Amazing!
