Una de las grandes preguntas de la biología del desarrollo es: ¿cómo saben las células qué tejido han de formar? La bióloga molecular Ángela Nieto, investiga en el Instituto de Neurociencias de Alicante el viaje de las células por el organismo y la simetría corporal, que no exactamente igual en todos los individuos. La neurobióloga de la visión, Conchi Lillo, investigadora en el Instituto de Neurociencias de Castilla y León, desvela los misterios del iris humano que las empresas tecnológicas están buscando comprar. span data-contrast="auto" xml:lang="ES-ES" lang="ES-ES" class="TextRun SCXW32390637 BCX0" style="accent-color: auto; place-content: normal; place-items: normal; place-self: auto; alignment-baseline: auto; animation: 0s ease 0s 1 normal none running none; animation-composition: replace; app-region: none; appearance: none; aspect-ratio: auto; backdrop-filter: none; backface-visibility: visible; background: none 0% 0% / auto repeat scroll padding-box border-box rgba(0, 0, 0, 0); background-blend-mode: normal; baseline-shift: 0px; baseline-source: auto; border-image: none 100% / 1 / 0 stretch; border-color: rgb(0, 0, 0); border-collapse: collapse; border-end-end-radius: 0px; border-end-start-radius: 0px; border-width: 0px; border-style: none; border-spacing: 0px; border-start-end-radius: 0px; border-start-start-radius: 0px; border-radius: 0px; inset: auto; box-shadow: none; box-sizing: content-box; break-after: auto; break-before: auto; break-inside: auto; buffered-rendering: auto; caption-side: top; caret-color: rgb(0, 0, 0); clear: none; clip: auto; clip-path: none; clip-rule: nonzero; color-interpolation: srgb; color-interpolation-filters: linearrgb; color-rendering: auto; color-scheme: normal; columns: auto; column-fill: balance; gap: normal; column-rule: 0px rgb(0, 0, 0); column-span: none; contain: none; contain-intrinsic-block-size: none; contain-intrinsic-size: none; contain-intrinsic-inline-size: none; container: none; content: normal; content-visibility: visible; counter-increment: none; counter-reset: none; counter-set: none; cursor: text; cx: 0px; cy: 0px; d: none; direction: ltr; display: inline; dominant-baseline: auto; empty-cells: show; fill: rgb(0, 0, 0); fill-opacity: 1; fill-rule: nonzero; filter: none; flex: 0 1 auto; flex-flow: row; float: none; flood-color: rgb(0, 0, 0); flood-opacity: 1; font-family: WordVisi_MSFontService, Calibri, Calibri_EmbeddedFont, Calibri_MSFontService, sans-serif; font-feature-settings: normal; font-kerning: none; font-optical-sizing: auto; font-palette: normal; font-size: 17.3333px; font-stretch: 100%; font-synthesis: weight style small-caps; font-variant-ligatures: none; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; font-variation-settings: normal; forced-color-adjust: auto; grid-area: auto; grid: none; height: auto; hyphenate-character: auto; hyphenate-limit-chars: auto; hyphens: manual; image-orientation: from-image; image-rendering: auto; initial-letter: normal; inline-size: auto; inset-block: auto; inset-inline: auto; isolation: auto; lighting-color: rgb(255, 255, 255); line-break: auto; line-height: 25.3px; list-style: outside none disc; marker: none; mask: none; mask-type: luminance; math-depth: 0; math-shift: normal; math-style: normal; max-height: none; max-width: none; min-height: 0px; min-width: 0px; mix-blend-mode: normal; object-fit: fill; object-position: 50% 50%; object-view-box: none; offset: normal; opacity: 1; order: 0; outline: rgb(0, 0, 0) none 0px; outline-offset: 0px; overflow: visible; overflow-anchor: auto; overflow-clip-margin: 0px; overflow-wrap: break-word; overlay: none; overscroll-behavior-block: auto; overscroll-behavior-inline: auto; overscroll-behavior: auto; page: auto; paint-order: normal; perspective: none; perspective-origin: 0px 0px; pointer-events: auto; position: static; quotes: auto; r: 0px; resize: none; rotate: none; ruby-position: ov
