Un nuevo análisis de la Universidad Queen Mary de Londres propone que las constantes físicas del universo ocupan un rango estrecho que permite que los líquidos fluyan adecuadamente dentro de las células vivas.

Investigadores dirigidos por el físico Kostya Trachenko sostienen que incluso cambios pequeños en valores como la constante de Planck o la carga del electrón alterarían la viscosidad lo suficiente como para interrumpir el transporte de nutrientes, el plegamiento de proteínas y otros procesos celulares necesarios para la vida.

Texas A&M researchers build customizable living vessel-on-a-chip to mimic branching, aneurysms and stenosis

Researchers at Texas A&M University say they have developed a customizable “vessel-chip” that recreates the complex shapes of human blood vessels—including branches, aneurysm-like bulges and stenosis-like narrowings—so scientists can study how altered blood flow affects endothelial cells and evaluate potential treatments without relying on animal models.

Scientists discover internal winds in cells linked to cancer spread

Researchers at Oregon Health & Science University have identified hidden fluid flows inside cells that rapidly transport proteins to the leading edge, challenging traditional views of cellular movement. The discovery, made during a classroom experiment, could explain why some cancer cells spread aggressively. The findings appear in Nature Communications.

Scientists find simple liquids fracture like solids under stress

Researchers at Drexel University have discovered that certain viscous liquids can snap apart like solids when stretched with sufficient force. The finding, detailed in a study published in Physical Review Letters, challenges traditional views of fluid dynamics by linking the behavior to viscosity rather than elasticity. This phenomenon was observed in simple liquids such as tar-like hydrocarbons and styrene oligomer.

Particles emerge from vacuum in proton collisions for first time

Physicists with the STAR collaboration have observed particles emerging directly from empty space during high-energy proton collisions at Brookhaven National Laboratory. The experiment provides strong evidence that mass can arise from vacuum fluctuations, as predicted by quantum chromodynamics. Quark-antiquark pairs promoted to real particles retained spin correlations tracing back to the vacuum.

Scientists develop lipid-coated nanopores for enhanced blue energy

10 de marzo de 2026 Reportado por IA

Researchers at EPFL have created a new membrane using lipid-coated nanopores that boosts the efficiency of blue energy production from mixing saltwater and freshwater. The innovation allows ions to pass through more smoothly, generating up to three times more power than existing technologies. This advance could make osmotic energy a more viable renewable source.
