Protein discovery could unlock the secret to better TB treatment

...cret to quicker, more effective treatment of TB by waking TB bacteria in the body. Once the TB bacteria are active again, the disease becomes treatable using common drugs like antibiotics. Scientists believe that uncovering the molecular structure of this protein will lead the way to designing drugs which e...

Wisconsin researchers identify sleep gene

...ves are slower during deep sleep and faster during waking times. One way of getting from the faster to the slower state is by opening ion channels, allowing potassium to flow through them. "Our hypothesis is that if you don't have potassium channels, you won't get slow waves," Cirelli says. "The cell membr...

Deep sleep short-circuits brain's grid of connectivity

... higher regions of the brain - regions that during waking hours are a bustling grid of neural dialogue - apparently lose their ability to communicate effectively, causing consciousness to fade. Writing today (Sept. 30) in the journal Science, a team of researchers led by University of Wisconsin-Madison pro...

New understanding of jet lag

...l timekeeper - the biological clock that regulates waking and sleeping cycles - has two parts that fall out of synchrony during light schedule shifts of six hours, the time it takes to fly across the Atlantic. The finding may explain, at least in part, why transmeridian travelers suffer from jet lag, the m...

Waking a sleeping virus

...ycle. Since ZEBRA is essential to the first steps, waking the virus, blocking it would be much better." To identify weak points of ZEBRA as potential drug targets Morand and Carlo Petosa from Müller's group created a high-resolution map of the protein's structure. Using the unique technology "platforms" th...

In other words, animals with an optimal time of torpor will win out over others, says Luis, who presented her findings at the 91st annual meeting of the Ecological Society of A...

First biomarker for human sleepiness identified in fruit flies

... lacking the gene for amylase had normal sleep and waking cycles, showing that while amylase is tightly linked to sleep drive, it is not actively involved in its regulation. "We're very pleased with how tightly amylase levels correlate with sleep debt, but for a good diagnostic test we're likely going to...

A potential biological cause for sudden infant death syndrome

...sitivity to carbon dioxide, and temperature during waking and sleep. When babies sleep face-down or have their faces covered by bedding, they are thought to re-breathe exhaled carbon dioxide, therefore breathing in less oxygen. Normally, the rise in carbon dioxide activates nerve cells in the brainstem, whi...

Out-of-body experiences may be caused by arousal system disturbances in brain

On average, the teachers had 1,800 occurrences of voicing per hour at work, compared to 1,200 per hour during non-work periods (for a total of as many a...
