Neurons Can Carry Multiple Signals At A Time

Back in the early days of telecommunications, engineers devised a clever way to send multiple telephone calls through a single wire at the same time. Called time-division multiplexing, this technique rapidly switches between sending pieces of each message. New research from Duke University shows that  in the brain may be capable of a similar strategy

Flesh-eating pathogen: A New Biomarker is Discovered

Imagine a pathogen that infects completely healthy people and can cause blindness in one day and flesh-eating infections, brain abscesses, and death in just a few days. Now imagine that this pathogen is also resistant to all antibiotics.

This is the nightmare scenario that obsesses Thomas A. Russo. Since seeing his first case in Buffalo seven years ago, he has been investigating hypervirulent Klebsiella pneumoniae, a rare but increasingly common strain of K. pneumoniae.

Brain Parts May Remain Conscious During General Anesthesia

A new research suggests that while patients under anesthetic might not be living out an Awake-type scenario, their brains are not exactly unconscious either. Instead, they are in a “sleeping state. Going under the knife while still awake is the stuff of nightmares. And while patients "waking up" during surgery is not entirely unheard of, it is extremely rare. In fact, experts believe it happens in just 0.005% of cases though there are certain factors that put some patients at a higher risk than others. The study was published in the journal Anesthesiology. 

Interaction Between Sleep And Wakefulness

A study aimed to identify the important players implicated in arousal regulation, sleep is an autonomic process and is not always under our direct, voluntary control. Awake or asleep, we are basically under the regulation of two biological processes: sleep homeostasis, commonly known as 'sleep pressure', and the circadian rhythm, otherwise known as the 'body clock'. These two processes work in harmony to promote good consolidated sleep at night. The study was published in the Journal of Neuroscience.

Leprosy Spread in Complacent Environment After Its Elimination

Leprosy remains an embarrassing indicator of India’s failure to address health inequities. Adivasis, who are 8.6% of the population, bear the burden of 18.8% of new leprosy cases. In states like Gujarat and Tripura, two-thirds of new leprosy patients are adivasis. Alarmingly, the proportion of districts with the prevalence of 1/10,000 population or more has climbed up to 18.8%, up from 15.3% in 2012.

Evidence of Phage Cooperation When Attacking CRISPR-Containing Bacteria

CRISPR, or clustered regularly interspaced short palindromic repeats, are an essential part of bacterial immunity designed to defend against foreign DNA. In bacteria, CRISPR acts just like it does in human cells as a pair of scissors, in their case with the goal of cutting strands of infecting DNA.

While researchers have known that CRISPR is found in roughly half of all bacteria in the wild, they did not know much about the molecular battle between CRISPRs and invading viruses or phages.

Analysis Of Nanostructured Bacteria

Researchers have now developed a nanostructured surface to accelerate wound healing after implantation and to better protect it against the attack of bacteria. Vasodilating stents, lab-on-chips for analysis on smallest areas, 3D cell culturing systems for tissue reconstruction: micro- and nanotechnology is gaining importance in the medical sector. It also opens up new potentials in the area of implantology.
