"Knowledge is Superpower"

Science is this glorious adventure into the unknown, the opportunity to discover things that nobody knew before. And that’s just an experience that’s not to be missed. But it’s also a motivated effort to try to help humankind. And maybe that’s just by increasing human knowledge—because that’s a way to make us a nobler species.

We do science and science communication not because they are easy but because they are difficult!

Forces driving epithelial wound healing
Abstract of the research paper:
A fundamental feature of multicellular organisms is their ability to self-repair wounds through the movement of epithelial cells into the damaged area. This collective cellular movement is commonly attributed to a combination of cell crawling and ‘purse-string’ contraction of a supracellular actomyosin ring. Here we show by direct experimental measurement that these two mechanisms are insufficient to explain force patterns observed during wound closure. At early stages of the process, leading actin protrusions generate traction forces that point away from the wound, showing that wound closure is initially driven by cell crawling. At later stages, we observed unanticipated patterns of traction forces pointing towards the wound. Such patterns have strong force components that are both radial and tangential to the wound. We show that these force components arise from tensions transmitted by a heterogeneous actomyosin ring to the underlying substrate through focal adhesions. The structural and mechanical organization reported here provides cells with a mechanism to close the wound by cooperatively compressing the underlying substrate.

At higher levels, fluoride in drinking water can lead to pitted teeth and discoloration. It also makes bones brittle and more prone to fractures. And recent studies have also linked high levels of fluoride exposure with IQ deficits.

A new study shows that weak electromagnetic stimulation could reorganize the brain with few side effects.
Researchers have shown that electromagnetic stimulation can alter brain organization which may make your brain work better.

In results from a study published in the Journal of Neuroscience, researchers from The University of Western Australia and the Université Pierre et Marie Curie in France demonstrated that weak sequential electromagnetic pulses (repetitive transcranial magnetic stimulation, or rTMS) on mice can shift abnormal neural connections to more normal locations.

The discovery has important implications for treatment of many nervous system disorders related to abnormal brain organisation such as depression, epilepsy and tinnitus.

How You Meditate Matters
Research shows that Vajrayana meditation can enhance cognitive performance, while Theravada meditation is relaxing.
not all meditation techniques produce similar effects of body and mind. Indeed, a study published in PLoS One demonstrates that different types of Buddhist meditation—namely the Vajrayana and Theravada styles of meditation—elicit qualitatively different influences on human physiology and behaviour, producing arousal and relaxation responses respectively.
The researchers had also observed an immediate dramatic increase in performance on cognitive tasks following only Vajrayana styles of meditation. They noted that such dramatic boost in attentional capacity is impossible during a state of relaxation. Their results show that Vajrayana and Theravada styles of meditation are based on different neurophysiological mechanisms, which give rise to either an arousal or relaxation response.

Bypassing The Brain To Walk Again
Bypassing the spinal cord with an artificial neural connection enables subjects to control their legs by swinging their arms.
A Japanese research group has successfully made an artificial connection from the brain to the locomotion center, bypassing the spinal cord with a computer interface. This research, published in the Journal of Neuroscience, allowed subjects to perform a walking-like behavior in their legs by swinging their arms.
Neural networks in the locomotion center of the spinal cord are capable of producing rhythmic movements, such as swimming and walking, even when isolated from the brain. The brain controls the spinal locomotion center by sending commands to the spinal locomotion center to start, stop and change waking speed. In most cases of spinal cord injury, the loss of this link from the brain to the locomotion center causes problems with walking.
Although gait disturbance in individuals with spinal cord injury is attributed to the interruption of neural pathways from brain to the spinal locomotor center, neural circuits located above and below the lesion maintain most of their functions. An artificial connection that bridges the lost pathway and connects brain to spinal circuits has potential to ameliorate the functional loss.

Asthma and odors: The role of risk perception in asthma exacerbation
Fragrances and strong odors have been characterized as putative triggers that may exacerbate asthma symptoms and many asthmatics readily avoid odors and fragranced products. However, the mechanism by which exposure to pure, non-irritating odorants can elicit an adverse reaction in asthmatic patients is still unclear and may involve both physiological and psychological processes. The aim of this study was to investigate how beliefs about an odor's relationship to asthmatic symptoms could affect the physiological and psychological responses of asthmatics.
Results

Predictably, manipulations of perceived risk altered both the quality ratings of the fragrance as well as the reported levels of asthma symptoms. Perceived risk also modulated the inflammatory airway response.
Conclusions

Expectations elicited by smelling a perceived harmful odor may affect airway physiology and impact asthma exacerbations.
Highlights

•Asthmatics were exposed to an odor characterized as ‘asthmogenic’ or ‘therapeutic’.

•Irritation and annoyance ratings were elevated in the asthmogenic group.

•The asthmogenic group showed a rapid and persistent increase in airway inflammation.
