Electromicrobiology is one of the rising subjects in the field of science. It combines the technology with biology.
In this subject, initially scientists found the transmission of electrical signals between the microbes. On a further note, in this subject, we study about the complex interaction between the microorganisms and technological devices while considering the novel electrical properties of the microorganisms i.e. accepting or donating the electrons from electrodes wi........

Nodding syndrome.Ever heard of it? Well, up until a few days ago I hadn't. That is before coming across articles on the topic by Richard Idro and colleagues* (open-access) and Angelina Kakooza-Mwesige and colleagues** (open-access). Whilst not specifically my line of expertise or interest, I was intrigued to read about how nodding and other symptoms of the epileptic variety, at least in some cases, seemed to be precipitated by food and showed a potential nutritional angle.Curving spacetime&........

Last year, I blogged about a new and very pretty way of displaying the data about the human ‘connectome’ – the wiring between different parts of the brain. But there are many beautiful ways of visualizing the brain’s connections, as neuroscientists Daniel Margulies and colleagues of Leipzig discuss in a colourful paper showcasing these techniques. Here, [...]... Read more »
Jean Jacques Hublin has a commentary  in the current issue of Nature, about making fossils available for scanning, digital replication, and ultimately hopefully open dissemination. As Hublin points out, it's a bit ridiculous that a fossil is a rare enough thing as it is, but even after their discovery, fossils "can become unreachable relics once they are in storage." Fortunately, Hublin goes on to point to online collections that are available to anyone interested. Somewhat ironically, t........ Read more »

Cooperation is a puzzle because it is not obvious why cooperation, which is good for the group, is so common, despite the fact that defection is often best for the individual.

One of the most valuable ponds in Alabama, if you ask me
was a drive from Auburn University to a conference in the Florida panhandle
that allowed us a short detour to visit one of the most storied wetlands in
Alabama herpetological history. But, I didn’t realize that at the time.

No, I'm not looking for people with lithe limbs to be photographed for money. Much more sexily, I'm referring to a recent paper (Pietak et al., 2013) that's found that the relative length of the segments of human limbs can be modeled with a log-periodic function:Figure 2 from Pietak et al. 2013. Human within-limb proportions are such that the length of each segment (e.g., H1-6) of a limb, from fingertip to shoulder (A) and to to hip (B), can be predicted by a logarithmic periodic function&........

Medieval alchemists devoted their lives to the pursuit of the infamous Philosopher's Stone, an elusive substance that was thought to convert base metals into valuable gold. Needless to say, nobody ever discovered the Philosopher’s Stone. Well, perhaps some alchemist did get lucky but was wise enough to keep the discovery secret. Instead of publishing the discovery and receiving the Nobel Prize for Alchemy, the lucky alchemist probably just walked around in junkyards, surreptitiously c........ Read more »

Researchers found that the children with autism are twice as fast as the normal children of their age in the sensitivity of motion.

Previously, researchers found that the autistic people have enhanced visual abilities with still images. Now, this is the first study to show that they are also highly sensitive to the motion.
In this study, researchers exposed the children to the brief video clips of moving black and........ Read more »

The human body contains trillions of cells, all derived from a single cell, or zygote, made by the fusion of an egg and a sperm. That single cell contains all the genetic information needed to develop into a human, and passes identical copies of that information to each new cell as it divides into the many diverse types of cells that make up a complex organism like a human being....

When we think of wounds, we don’t typically think of them as part of normal, healthy function. Micro-wounds, however, form when white blood cells have to cross the barrier in our blood vessels to get to an injury or infection. These micro-wounds happen all the time, and our cells heal these wounds efficiently and elegantly.One of the most important barriers in our body is that created by the vascular endothelium. Vascular endothelial cells line all of our blood vessels—from........ Read more »
