A new type of memory storage on the horizon

by Gabriel in Lunatic Laboratories

For those of us old enough to remember the days of the Apple II, you know that storage has exponentially increased. Even just 10 years ago 20+ gigs of data seemed huge, now my cellphone has 64 gigs. Yet we still need more data storage and we are looking for new ways to get it. Now a way to use weak molecular bonding interactions to create well-ordered and stable metal–organic monolayers with optoelectronic properties has been found. The development could form the basis for the scalable fabrica........ Read more »

Move over solar pannels, introducing spray-on solar cells

by Gabriel in Lunatic Laboratories

Solar panels, they are big, heavy, cannot flex, and are still very inefficient. While efficiency isn’t the big issue, flexibility has relegated solar panels to rooftops and solar farms. Well that is until now, researchers have just invented a new way to spray solar cells onto flexible surfaces using miniscule light-sensitive materials known as colloidal quantum dots (CQDs)—a major step toward making spray-on solar cells easy and cheap to manufacture....

ALMA Japan: Hi-Def Imaging of Spiral Gas Arms from Twin Baby Stars (w/video)

by DJ Busby in Astronasty

We know that about half the the stars out there (with sizes close to that of our sun) are binary systems. However, for a long time we've been lacking information on how they develop, since it's not been easy to get a whole lot of data from surrounding scattered mass that's so damned far away! Congrats to all involved!... Read more »

Hoe komt het dat een liedje in je hoofd blijft hangen? [Dutch]

by Henkjan Honing in Music Matters

De hele dag dat ene hitje in je hoofd: een oorwurm! Muziekproducenten kunnen het zich niet beter wensen. Wat maakt dat liedje nou zo makkelijk te onthouden? En hoe kan het dat je dat ene nummer zo snel herkent? Muziekwetenschapper prof. dr. Henkjan Honing (UvA) legt uit wat de ingrediënten zijn voor het maken van een ware muziekhit en waardoor luisteraars zo ‘Hooked on Music’ zijn…... Read more »

How Slime Molds Our World

by Mark Lasbury in As Many Exceptions As Rules

Fungus-like protists have amazing tales to tell. One phylum has been shown to ranch bacteria and hire cowhands to guard them. One phylum has slime mold that can find its way through a maze and is used to model mathematics for video games. Finally, one phylum is responsible for the glut of Irish priests and policeman in late 1800’s America.... Read more »

Illusion Makes People Speak with the Voice of Their Avatar

by Elizabeth Preston in Inkfish

Think you’re in control of your own body? A simple virtual-reality session could not only make you feel like an avatar’s body is your own, but make you speak more like the digital character. First there was the rubber-hand illusion, a classic experiment that showed syncing up someone’s touch perceptions with what they see happening […]The post Illusion Makes People Speak with the Voice of Their Avatar appeared first on Inkfish....

Blu-ray solar power

by Gabriel in Lunatic Laboratories

So here’s something you don’t see everyday. Blu-ray disks, you know the stuff we use for video games or DVDs also improve the performance of solar cells—suggesting a second use for unwanted discs—according to new research from Northwestern University. As surprising as this was, there is even better news, we know why they improve performance.... Read more »

The impact of powered prosthetic failures on the user

by Gabriel in Lunatic Laboratories

Prosthetics have come a long way in a relatively short amount of time. With the ongoing wars in the middle east the need for better prosthetics technologies has become more apparent, to this end we now have prosthetics that will allow a person to "feel", we even have motorized prosthetics that will help allow a more fluid walk, but while powered lower limb prosthetics hold promise for improving the mobility of amputees, errors in the technology may also cause some users to stumble or fall.

What is the most instantly recognisable song?

by Henkjan Honing in Music Matters

Everyone knows a hook when they hear one, but scientists don’t know why. By playing the Hooked on Music game you are exploring the science of songs and helping us to unlock what makes music catchy.

Last weekend the preliminary outcome of the online game was announced in Manchester, UK at the MOSI, answering the question: What is the most instantly recognisable song? Interestingly, numerous media started to report on this. A small media hype?... Read more »

Reshaping the Limits of Synthetic Biology

by Gabriel in Lunatic Laboratories

Ever think you could have built something better if you had a hand in the design? Sometimes people just have a desire to make, after all the maker movement is huge for a reason. Well geneticists have a new toy tool to play with —dubbed “the telomerator”—that could redefine the limits of synthetic biology and advance how successfully living things can be engineered or constructed in the laboratory based on an organism’s genetic, chemical base-pair structure. How cool is that?!... Read more »

Collective Structures in Software Projects

by Jörg Friedrich in Software Engineering Economics

To understand the social dynamics of complex software development processes, it is necessary to analyze in which structures the persons involved and how this involvement affected their work. Damian Tamburri has in recent years identified the relevant social structures in a number of publications, analyzed and graded on their effect. He first distinguishes four basic […]... Read more »

Dude, wheres my Hover Car? Oh wait…

by Gabriel in Lunatic Laboratories

We all (of a certain age) remember the Jetsons, a futuristic family with hi-tech gadgets and gizmos. However, nothing said, “the future is here” quite like things hovering. Even in the movie Back to the future, they have hover boards and flying cars. Unfortunately we don’t, which is a shame because according to the 1950’s we are the future, we should have hover-cars and hover boards… well the wait is over. Yep, introducing the first real hover board!... Read more »

A Venusian Mystery Explored Once More

by Gabriel in Lunatic Laboratories

Venus, the place where women are from... supposedly. To say Venus has a harsh climate would be an understatement, this is one of many reasons why we will never (or maybe not soon) see a "long lasting" Venus rover counterpart to our Mars rover missions. Still, the planet (much like all the other plants) can teach us a lot about not just our own origins, but the origins of the universe. Also like all our neighbor planets Venus is hiding something beneath its brilliant shroud of clouds, a mystery t........ Read more »

Carbon’s Place in a Silicon World

by Gabriel in Lunatic Laboratories

Everything is silicon based, well mainly your computer, your TV, your ipad, and pretty much every piece of electronics in existence. Still the world turns and so does technology; at a similarly fast pace no less. Even as the 2014 Nobel Prize in Physics has enshrined light emitting diodes (LEDs) as the single most significant and disruptive energy-efficient lighting solution of today, scientists around the world continue unabated to search for the even-better-bulbs of tomorrow. In this search we ........ Read more »
