Humanos muertos vs humanos vivos 


Uno de los estudios  demográficos más extendidos refleja que el número de personas que viven actualmente en el planeta (alrededor de 7.000 millones de personas y subiendo) excede al número total de humanos que poblaron alguna vez la Tierra durante los siglos anteriores. La realidad, según los cálculos realizados por la Oficina de Referencia de la Población (Population Reference Bureau), el número de humanos vivos actualmente es apenas una pequeña fracción de los que vivieron alguna vez.


Para realizar la estimación, el demógrafo Carl Haub decidió empezar a contar desde hace unos 50.000 años, en la que no hay duda que ya había Homo sapiens poblando nuestro planeta. Aunque no hay mucha información, Haub calculó los ritmos de crecimiento demográfico en diversas etapas históricas y llegó a la conclusión de que en este periodo de 50.000 años nacieron y murieron unos 107.000 millones de personas en el planeta. En cifras globales, los muertos del planeta superan por 100.000 millones a los vivos actualmente, así que si hubiera un apocalipsis zombi tendríamos que combatir contra un ejército bastante superior en número.

Tiny Machines, Huge Impact: Molecular Jackhammers Wipe Out Cancer Cells

  Tiny Machines, Huge Impact: Molecular Jackhammers Wipe Out Cancer Cells 1. A Revolutionary Cancer-Killing Tool Scientists from Rice University, Texas A&M, and the University of Texas MD Anderson have invented a radical tool that destroys 99% of cancer cells —without using drugs, radiation, or heat. Instead, it uses special dye molecules and gently applied light to physically rip cancer cells apart from the inside. This technique—nicknamed “molecular jackhammers” —has achieved astonishing results in lab cultures and animal studies. These molecular jackhammers are based on a familiar dye used in hospitals: aminocyanine . When exposed to near-infrared light , this dye vibrates at incredibly high frequencies—up to 1 trillion times per second. These vibrations break open cancer cell membranes, causing cells to collapse. Published in the journal Nature Chemistry , this discovery offers a new frontier in cancer treatment by physically destroying tumor cells rather than pois...

A New Kind of Life: Scientists Push the Boundaries of Genetics

A New Kind of Life: Scientists Push the Boundaries of Genetics The strange idea of making life “better” It almost sounds like science fiction: a team of researchers in Cambridge claims they’ve created a form of life that’s leaner, more efficient, maybe even “more perfect” than anything nature has ever managed. That phrase more perfect is tricky, of course, because perfection in biology is a moving target. What works in one environment is useless in another. Still, the claim is bold. The scientists didn’t just tweak a gene here or there, like swapping out corn DNA to make it more pestresistant. They rewrote the actual structure of life’s code, stripping it down, removing what they saw as excess baggage. The result is something they call Syn57 : a genetically engineered strain of E. coli. Yes, the same bacterium you’ve probably heard about from grim foodsafety warnings. Only this version isn’t lurking on a questionable hot dogit’s a reimagined lifeform built line by line from altere...
