5+ hour, 27+ min ago   (492+ words) The Times of India Viruses have been attacking living organisms for billions of years, long before humans first appeared on Earth Yet one of the biggest questions in biology has remained remarkably difficult to answer: where did the human immune…...

3+ hour, 34+ min ago   (608+ words) The insula, a folded region tucked deep within the lateral sulcus of the cerebral cortex, is emerging as one of neuroscience’s most important—and most complicated—research targets. Once treated largely as a sensory relay, the insular cortex is now…...

11+ hour, 28+ min ago   (477+ words) Hydrogels are among the most promising materials in modern biomedicine. They are soft, water-rich networks that can resemble the physical environment of living tissue, making them useful for drug delivery, wound treatment, tissue engineering and regenerative medicine....

18+ hour, 51+ min ago   (511+ words) The death of a 6-year-old girl allegedly linked to an experimental gene-editing clinical trial in Shanghai has sparked widespread concern over the safety and ethical oversight of medical research involving human beings. The girl had Snijders Blok-Campeau syndrome, a rare…...

17+ hour, 23+ min ago   (448+ words) A new study has identified an important spatial principle governing how mitochondria support developing neurons: the machinery that controls mitochondrial calcium is not distributed evenly throughout the cell. Instead, calcium regulators appear to be positioned asymmetrically across neuronal compartments, allowing…...

Time-lapse confocal images of a liposome showing bleb formation and expansion. view more A system of artificial cells to study cell morphogenesis As Miyazaki explains, "by reconstructing membrane morphogenesis from purified proteins, we showed that local interactions within the…...

1+ day, 10+ hour ago   (458+ words) Ultrasound can make chemistry happen inside a liquid by creating microscopic bubbles that collapse with extraordinary force. Yet a new computational study suggests that turning up the sound does not always make these reactions more powerful....

1+ day, 12+ hour ago   (468+ words) Researchers in Japan have reconstructed a key aspect of cellular behavior inside artificial cells, showing that a network of actin and myosin proteins can produce large-scale changes in cell shape—and even establish a front and rear—without the biochemical…...

1+ day, 17+ hour ago   (447+ words) Scientists have uncovered a surprising molecular double life at the heart of plant development. A protein long associated with activating genes has now been shown to directly stimulate a major gene-silencing machine, revealing how plants may switch between opposing chromatin…...
