They resemble a tree-like structure, forming projections that become stimulated by other neurons and conduct the electrochemical charge to the cell body (or, more rarely, directly to the axons). Kapalka, in Nutritional and Herbal Therapies for Children and Adolescents, 2010 The Dendritesĭendrites are appendages that are designed to receive communications from other cells. The study also found that the precise color changes with varying exposure to light, indicating that these creatures may be able to adapt their disguise as they travel through differing light exposure levels.īeyond literally shedding light on these unique creatures, the finding may one day be responsible for an impressive range of color-changing biomimetic devices.George M. Furthermore, the precise structure of the sphere impacts the color of the shield this variation enables creatures to evolve to match their camouflage to the particular ocean water in which they dwell. These spheres, made of plates of isoxanthopterin formed into balls, cover the dark-colored eyes of larvae enabling them to remain hidden from view. Young crustacean larvae typically grow glassy, crystalline spheres above their eyes two researchers at Union College have determined that this is a strategy to camouflage themselves from predators.
This finding radically changes the understanding behind psychedelics and their impact on the brain and may be the source of future treatments.ĭecoding color-changing crustacean larvae eyes Researchers assumed that psychedelics activated proteins that prompted dendrite growth however, it turns out that rather than external activation, psychedelics-which are “greasy”-enter the cell and prompt growth internally.įurther experiments demonstrated that if serotonin artificially enters a cell, it will prompt the same response. Despite this, the mechanism behind this growth was previously unknown. It has been known that psychedelics can have positive impacts on mental health, being capable of addressing depression and post-traumatic stress disorder, by repairing the dendrite branches that connect cortical neurons. Psychedelics slip inside and heal nerve cellsĪ recently published study from the University of California Davis discovered that unlike other substances, psychedelics - including the psilocin found in magic mushrooms - trigger neuron growth by slipping through the cellular membrane to the interior of the cell. The team envisions that this technology could be used to move cells and tissue without interfering with their physiology. This is taken a step further by introducing acoustic perturbations across all three dimensions to enable 3D assemblage. This technique enabled materials to be conformed across two dimensions. Previous work used specifically generated plates whose topology encodes patterns of different amplitudes of sound, generating fields of high and low pressure.
However, a team of researchers at the Max Planck Institute for Medical Research and the Heidelberg University have taken advantage of acoustic levitation to precisely control the displacement of microscopic objects at the sub-millimeter scale using sound waves. Sound is not thought to be useful for manufacturing. At this temperature, a thermal receptor called BRTNaC1 activates and notifies the centipede about the presence of sunlight.Įven without eyes, this creature packs a mighty punch, capable of subduing mice fifteen times its own size and sending humans to the hospital. Rather, upon contacting sunlight, the little critter’s antenna heats up from 28☌ all the way to 37☌. However, the Chinese red-headed centipede, also known as Scolopendra subspinipes mutilans, has no light-sensing proteins. Usually, creatures can see the world around them and sense sunlight through photoreceptors, cells that directly convert light to discernible signals. Some of this week’s greatest discoveries include two unique animals, the power of psychedelics and breakthroughs in the use of acoustic levitation.Ĭentipede uses heat, not eyes, to detect sunlightĪ team of Chinese investigators has identified a thermal receptor that allows the Chinese red-headed centipede to see without vision sensors. Valentine’s Day may have come and gone but our love of science is as strong as ever.
