Neurons, the nerve cells that send and receive electrical signals within the body, are one of those things that most of us probably don’t give a lot of thought to. Educational entrepreneurs Timothy Marzullo and Gregory Gage, however, think about them a lot. They think about them so much, in fact, that they’ve designed a gadget that lets anyone listen to the neural electrical activity of bugs, and conduct a series of interesting experiments. It’s called the SpikerBox, and oh yeah – in order to use it, you have to take the leg off of a cockroach. Read More
While it’s generally accepted that memories are stored somewhere, somehow in our brains, the exact process has never been entirely understood. Strengthened synaptic connections between neurons definitely have something to do with it, although the synaptic membranes involved are constantly degrading and being replaced – this seems to be somewhat at odds with the fact that some memories can last for a person’s lifetime. Now, a team of scientists believe that they may have figured out what’s going on. Their findings could have huge implications for the treatment of diseases such as Alzheimer's. Read More
Fans of the classic 1982 science fiction movie Blade Runner will remember the ESPER machine that allows Deckard to zoom in and see around corners in a two-dimensional photograph. While such technology is still some way off, researchers in MIT’s Media Lab have developed a system using a femtosecond laser that can reproduce low-resolution 3D images of objects that lie outside a camera’s line of sight.

Researchers at the University of Sheffield have created what sounds impossible - even nonsensical: an experimental electron microscope without lenses that not only works, but is orders of magnitude more powerful than current models. By means of a new form of mathematical analysis, scientists can take the meaningless patterns of dots and circles created by the lens-less microscope and create images that are of high resolution and contrast and, potentially, up to 100 times greater magnification.

For the predicted hydrogen economy to become a reality, fuel cells must become more efficient and cost effective. Researchers from the University of Central Florida (UCF) claim to have addressed both these problems by creating a sandwich-like structure that allows more abundant materials to be used as catalysts in hydrogen fuel cells.

When anthrax spores go dormant, they develop a tough outer coating that can withstand heat, radiation and antibiotics, in one case even allowing them to come back to life after 250 million years. It seems that such spores could be no match, however, for a special pair of silk curtains. Read More
Neutrinos have been in the news recently, and although it appears that they probably do not travel faster than light, they still hold court as three of the strangest of the known subatomic particles. Undeterred by these arcane particles, Fermilab scientists have succeeded in communicating with neutrino pulses through 240 meters (262 yards) of rock at a rate of 0.1 bits per second. Read More
Earlier this year we reported that researchers had implanted a cockroach with an enzyme-based biofuel cell that could potentially be used to power various sensors, recording devices, or electronics used to control an insect cyborg. While it may not be the most dynamic of creatures, a team from Clarkson University has now performed a similar feat with a living snail. Read More
Imagine a pair of rubber gloves whose surface texture could be altered on demand to provide more grip for climbing. Or maybe gloves with "fingerprints" that can be changed in the blink of an eye. They are just a couple of the many potential applications envisioned by researchers at Duke University for a process they have developed that allows the texture of plastics to be changed at will.

The NIST-F1 atomic clock that currently serves as primary time and frequency standard for the U.S. is expected to neither gain nor lose a second in more than 100 million years. That might sound pretty accurate, but a proposed nuclear clock could make it look like a cheap digital wristwatch. It is claimed that the proposed clock would neither gain nor lose 1/20th of a second in 14 billion years. To put that in context, that’s the estimated age of the universe. Read More
