Study proposes that the “fight or flight” response is triggered by your bones, NOT adrenaline
In the face of fear and apparent danger, both humans and animals initiate an acute reaction to stress in their bodies. Their breath quickens, their pupils dilate and their hearts begin to pound faster than usual. These programmed changes occur as part of the so-called “fight-or-flight” response. Scientists have long believed that the hormone called adrenaline triggers […]

Undersea eruption creates giant sheet of pumice that has floated across the Pacific Ocean
Undersea eruptions happen more often than people think. These eruptions are thought to shape features of the ocean, such as ridges and rises. Nonetheless, undersea eruptions are a lot less spectacular than their land counterparts, and it isn’t often that people get to see their ramifications on the ocean surface. So much to both sailors and […]

Shedding light on animal behavior: Rats can learn to play hide-and-seek just for fun, say scientists
In a recent breakthrough, scientists found that rats can be taught to play hide-and-seek just for the fun of it. The bizarre experiment, described in the journal Science, involved teaching rats both the hiding and seeking roles using social interactions and positive reinforcement. The German neuroscientists behind the experiment noted that the rats squeaked if […]

Microencapsulated compound from thyme essential oil kills larvae of dengue mosquitoes, study finds
Dengue is a mosquito-borne tropical disease that continues to be a pressing problem in some countries. Despite being painful and debilitating, it remains a neglected disease due to scant research, and there isn’t a range of treatments to choose from outside of bed rest and medication. In a major breakthrough, scientists from the University of Sao Paulo (USP) […]

Insulin resistance happens in the gut – but how? Researchers explain
Insulin resistance is a metabolic condition often studied in relation to diabetes. This is because it is considered a precursor to Type 2 diabetes. According to a group of researchers from Canada and the U.S., obesity can bring about insulin resistance, and it all starts in the gut. Published in the journal Nature Communications, their groundbreaking finding […]

Awareness while in a coma is common, but doctors FAIL to “listen to and respect patient experiences”
Comatose patients are thought to remain in a state of limbo – neither conscious nor unconscious – dubbed the “vegetative state.” The unique nature of this state often complicates treatments and therapies for these patients. For this reason, physicians might be shocked to hear about comatose patients regaining consciousness and snapping out of their condition. But Toronto-based author […]

Are you resilient? Researchers identify brain receptor crucial to regulating stress response
Repeated exposure to stressful conditions can increase the incidence of mental disorders, such as depression and post-traumatic stress disorder (PTSD). But scientists have recently discovered a lipid molecule that promotes stress resilience when expressed at high levels in the brain. In a recent study published in the journal Nature Communications, American researchers reported that sphingosine-1-phosphate receptor 3 (S1PR3), which functions as […]

Is this why kids are so happy? Researchers discover anti-inflammatory fat in soil-dwelling bacterium that can help relieve stress
A fat molecule found in Mycobacterium vaccae, a soil-dwelling bacterium, is behind its potent anti-stress effects, according to a recent study. Published in Psychopharmacology, it revealed that a lipid called 10(Z)-hexadecenoic acid in M. vaccae inhibits inflammation in the brain. The researchers behind the study also reported that cells became more resistant to inflammation upon exposure to the said […]

Hope for arthritis sufferers: Researchers identify a chemical that can stop inflammatory cell death
A chemical called necrosulfonamide may help inhibit “cellular suicide” linked to arthritis, a recent animal study showed. Published in Science Immunology, the study revealed that necrosulfonamide can prevent pyroptosis, a highly inflammatory form of programmed cell death that contributes to conditions like arthritis, live disease and inflammatory bowel disease (IBD). (Related: Cannabis found to reduce the symptoms of IBD.) The undesirable effects of pyroptosis […]

Unique pattern in the blood may serve as an early warning sign for seizures
Researchers have discovered a group of molecules in the blood that can help predict an epileptic seizure. Their findings, published in The Journal of Clinical Investigation, revealed that fragment levels of three transfer ribonucleic acid (tRNA) are higher in pre-seizure blood samples from epileptics than post-seizure blood samples, and even samples from healthy controls. The researchers hope that their findings can be […]
