Implicit Neural Representations and SIREN: Encoding Signals as Continuous Functions
5+ hour, 34+ min ago (29+ words) Day 11 of an ongoing daily series on advanced machine learning concepts Abstract Images, 3D shapes, and audio are …...
Heart cells can ‘remember’ stress and use it for protection during chemotherapy
11+ hour, 30+ min ago (1157+ words) Early stress in mitochondria before birth helped mouse hearts resist later chemotherapy damage by creating lasting protective changes. Chemotherapy can save lives, but some drugs can also put the heart under serious strain. Doxorubicin, a chemotherapy used against several cancers,…...
Synaptotagmins: How Calcium-Sensing Proteins Decide Whether Neurons Thrive
12+ hour, 21+ min ago (71+ words) Every thought, movement, and memory depends on an almost unimaginably fast molecular event: the fusion of synaptic vesicles with the membrane of a neuron, releasing neurotransmitters across the synapse in a fraction of a millisecond. At the heart of this…...
Wireless ‘WILD’ Device Records and Steers Brain Activity in Freely
14+ hour, 39+ min ago (598+ words) For decades, neuroscientists have faced an uncomfortable trade-off: the equipment that lets them eavesdrop on the brain has too often prevented animals from behaving like themselves. Tethered recording systems, for all their fidelity, anchor a mouse to a cable, restricting…...
Cryo-EM Captures Hidden Pre-Active State That Switches On the Brain’s
14+ hour, 39+ min ago (663+ words) For decades, neuroscientists have marveled at the sheer speed of communication in the brain, and much of that speed depends on a single family of proteins known as AMPA receptors....
Rare Gene Variants May Explain Why Some Brains Are More Vulnerable to
14+ hour, 59+ min ago (730+ words) Why does a seemingly minor knock to the head leave one person with a headache that fades within days, while another suffers months of dizziness, fatigue, and memory problems? A new study suggests that part of the answer may be…...
Ionic Gels Bring Neural-Like Signal Processing to Soft Electronics
1+ day, 1+ hour ago (831+ words) The human brain computes with ions. Every thought, memory and movement begins with charged atoms drifting across membranes, accumulating at junctions and triggering cascades of electrochemical activity that no silicon circuit has ever fully replicated. Now, a wave of research…...
Elderly Blood May Hold Regenerative Power, Proteomic Map of Platelet-Rich
1+ day, 2+ hour ago (838+ words) Platelet-rich plasma, the amber-colored concentrate spun from a patient’s own blood and injected back into damaged tendons, joints, and wounds, has long occupied a curious place in medicine: widely used, vigorously marketed, yet scientifically underdefined. Now a team of researchers…...
Mitochondrial dysfunction in granulosa cells is associated with impaired
1+ day, 2+ hour ago (80+ words) Granulosa cells, the specialized cells that nurse a developing ovarian follicle and prepare the egg for ovulation, appear to be working with compromised cellular machinery in women with polycystic ovary syndrome, according to a new study published in the Journal…...
Silent fMRI Framework Captures Brain-Wide Networks in Behaving Mice
1+ day, 4+ hour ago (759+ words) For decades, functional magnetic resonance imaging has offered scientists an unmatched window into the human brain, revealing whole-brain networks at work without a single incision. Yet when researchers attempt to bring that same power to bear on the smallest and…...
