Teachers at Garfield High School were winding down classes for the approaching lunch break when they heard the startling sound of people — they were not sure who — running through the halls, pounding on classroom doors. “Walkout!” they were shouting. “Walkout!”They looked on in disbelief as hundreds of students streamed out of classrooms and assembled before the school entrance, their clenched fists held high. “Viva la revolución!” they called out. “Education, not eradication!” Soon, sheriff’s deputies were rumbling…

A groundbreaking study reveals dopamine’s crucial role in controlling movement sequence lengths, shedding light on potential treatments for Parkinson’s Disease symptoms beyond traditional reward and pleasure associations. Credit: SciTechDaily.comDopamine’s influence extends to regulating movement lengths, offering new therapeutic targets for Parkinson’s Disease.Dopamine, a chemical messenger in the brain, is mostly known for its role in how we experience pleasure and reward. However, new research from the Champalimaud…

In their latest article, published in Humanities and Social Sciences Communications, UMass Amherst Associate Professor of History Kevin Young and Yale University environmental social scientist Laura Thomas-Walters ask: What are the lessons from that monumental victory for today's climate movement?…

At the turn of the millennium, he took a position at Princeton with the notion that the institutional pedigree might earn an audience for his “crazy” idea. Not long after he arrived, the chief of NASA’s Jet Propulsion Laboratory came for a talk, and Wikelski asked whether the agency would benefit from a satellite system that could track birds. “He looked at me as if I came from a different planet,” Wikelski remembers. Still, he got a meeting with NASA—though he says he was laughed out of the building. By this time, the…

Recent research utilizing optogenetics challenges existing views on sensory processing in the brain, showing that sensory modulation during movement is primarily influenced by inputs from the secondary somatosensory cortex and sensory thalamus, not the primary motor cortex. This discovery has significant implications for developing technologies that mimic human sensory-motor integration, offering new insights into the brain’s complex functions.Scientists have revealed new understandings of the way body movements impact…

Recent research on the fossil ape Lufengpithecus’s inner ear structures offers new clues to the evolutionary steps towards human bipedalism, revealing the significant roles of the inner ear and climate change in this evolutionary journey.

Scientists have boosted the motility of sluggish sperm by up to 266%, by blasting the cells with noninvasive, 40-MHz ultrasound waves to induce movement. Capturing the technique's impact on individual sperm cells, the study opens the door to new non-invasive fertility treatments. Encasing single sperm cells in microdroplets for the first time, researchers from Australia's Monash University have demonstrated how 20-second bursts of ultrasound 'revived' immotile sperm, spurring 59% of the treated individuals into action.…

Oscar Wilde always imposed. Meeting him in 1892, the French writer Jules Renard reported: “He offers you a cigarette, but selects it himself. He does not walk around a table: he moves the table out of the way … He is enormous, and carries an enormous cane.” The affectations of dress and manner; the extraordinary, magnetic talk; the flourished epigrams; the startling, needling essays, stories and plays – all these were impositions. They were how Wilde forced himself on the attention of the world, made himself notorious,…

Cardano (ADA) is an altcoin to watch right now as a renowned cryptocurrency trader, Ali Martinez, predicts its prices will surge by as much as 1,300% in 2024. ADA prices dropped as low as $0.22 last September but went as high as $0.66 before the year came to an end. Prices have now settled back down at $0.52 so now might be a good time to accumulate some cheap tokens.  ADA’s trading volume has increased by over 100% in the past week, so Martinez might be onto something.  InQubeta (QUBE) is another…
