A Microsyringe to Take the Pain out of Shots

by Hector Munoz in Microfluidic Future

Back when I was in sixth grade, I remember reading a little blurb in some science magazine at school that in the future we could receive shots via a method that would feel as soft as a banana peel. Although I’m now a champ at taking shots, it’s still not a bad idea. We’ve had transdermal patches (think nicotine and birth control) for some time now, but those release their medicine over a period of time. A syringe is capable of delivering a dose at once, and can take a biologica........ Read more »

Mirror, Mirror on the wall, Am I healthy after all?

by Aurametrix team in Health Technologies

Health gadgets continue to evolve in many forms and shapes - from something that fits in your pocket to something that is wearable or walkable. Everyday objects are turning into "Smart objects", building the foundation for the next version of the Internet. And it's not all smoke and mirrors. So let's talk about mirrors. Fairy tales and science fiction stories often pave the way to real world technology. Magic mirrors have been used in Snow White and Harry Potter's world. Now you can get one, too........ Read more »

Quantum computers | Κβαντικοί υπολογιστές

by Perikis Livas in Tracing Knowledge

A research team led by Australian engineers has created the first working quantum bit based on a single atom in silicon, opening the way to ultra-powerful quantum computers of the future.

In a landmark paper published today in the journal Nature, the team describes how it was able to both read and write information using the spin, or magnetic orientation, of an electron bound to a single phosphorus atom embedded in a silicon chip.... Read more »

Can Video Games Teach Kids “Grit”?

by Eric Horowitz in peer-reviewed by my neurons

KIPP’s character report card and Paul Tough’s new book have laudably placed an emphasis on how emotional skills and character traits (e.g. persistence, curiosity, optimism, etc.) influence a child’s academic trajectory. Yet the question remains, will our education system make a real effort to emphasize these new ideas, or will they join things like Carol [...]... Read more »

OMG! An Open Molecule Generator!

by egonw in Chem-bla-ics

Earlier this week an important cheminformatics paper appeared in the Journal of Cheminformatics. It is about the Open Molecule Generator (see below for the paper). This was one important piece of functionality still missing from Open Source cheminformatics. This works uses the Chemistry Development Kit, and was written by Julio Peironcely.

The Analytical Biosciences' group of Prof. Hankemeier (and many others, including also Theo Reijmers) and funded by the Netherlands Metab........ Read more »

New Caledonian crows reason about hidden causal agents

by Rogue Medic in Rogue Medic

We have generally believed that animals are not capable of very complex thought, even though many species use tools and engage in other complex behaviors.

Even a bird brain appears to be capable of understanding things that are not visible may be affecting their environment.

This study looks at whether New Caledonian crows, that were caught just for this experiment, are capable of attributing actions to a hidden cause, when they see that possible cause come and go.... Read more »

How to Build a Neuron: Shortcuts

by TheCellularScale in The Cellular Scale

So you want to build a neuron, but don't have the time to fill and stain it, digitally reconstruct it, or even to knit one. Knitting Neuroscience from Knit a Neuron Well you are in luck because a lot of scientists have collected a lot of data already and some of them are even willing to openly share their work.  While it is great that people are willing to share their data, that willingness alone is not enough to actually make the data widely accessible (or searchable for that mat........

This is your brain on implants (spoiler: it’s better)

by aimee in misc.ience

Today, the Journal of Neural Engineering published rather an interesting paper. In it, they showed that they had been able to restore (and in some cases, improve) decision-making ability in primates through the use of an implanted prosthetic. Sounds like something out of science fiction, doesn’t it?     The region of the brain responsible [...]

Coming Soon: New Species of Metals

by Andrew Porterfield in United Academics

Most metallic things around us—bridges, microchip wires, buildings—are made of arrays of tiny crystals that owe their strength to an orderly, repeating pattern of grains. However, these mixtures, or alloys, of different metals are unstable; under heat or stress they tend to meld together and become larger and weaker. But the right mix can produce a metal that’s stronger, more heat-resistant and capable of creating structures never thought possible.... Read more »

Here Come The Cyborgs

by gunnardw in The Beast, the Bard and the Bot

Cyborgs, or cybernetic organisms, are creatures in which biological tissues and artificial additions are closely intertwined. Well-known recent examples include moths and beetles that can be controlled through the use of electronic steering mechanisms attached to their brains. But, the … Continue reading →... Read more »

How to Build a Neuron: Step 2

Recently we've discussed the first step in how to build a neuron. Today we will discuss step 2: reconstructing that stained cell.Hippocampus CA1 Pyramidal neuron (from are a couple of ways that you turn an image (or image stack) of a neuron into a digital neuron file like the one pictured above.  Basically there is an easy way and a hard way.  The hard way is to reconstruct the neuron manually, where you literally trace the neuron by hand.  The easy way is to........

how to weave machinery into biology

by Greg Fish in weird things

As we’re starting to test artificially grown organs, scientists are wondering how to make sure that their methods result in viable tissues. One of the first steps was to take organ growth into three dimensions, letting the cells grow on a scaffold and self-organize into the right muscles, valves, and other soft tissue. Usually these scaffolds are derived from existing organs purified of all their old cells and many are designed to break down into [...]... Read more »

Video Tip of the Week: GenoCAD for Synthetic Biology

by Mary in OpenHelix

The field of synthetic biology has been simmering for quite a while. It occasionally takes a big leap, such as when Venter’s team published about their work on M. genitalium, and it took a big leap recently with the paper about modeling a lot of the cellular processes in a simple cell that I talked [...]...
