In a step toward sophisticated artificial cells, scientists have engineered a silicon chip that can produce proteins from DNA, the most basic function of life.

Several teams reported on insights gleaned from live-cell images obtained through the use of super-resolution microscopy at this week’s American Society for Cell Biology (ASCB) annual meeting held in Philadelphia.

A year after tackling how close together prime number pairs can stay, mathematicians have now made the first major advance in 76 years in understanding how far apart primes can be.

Los genomas de 48 especies de aves revelan el Big Bang biológico tras la extinción de los dinosaurios

In times of trouble, multiple studies have shown, more girls are born than boys. No one knows why, but men need not worry about being overrun by women. An analysis of old church records in Finland has revealed that the boys that are born in stressful times survive better than those born during less challenging periods. The work helps explain why women may have evolved a tendency to abort certain males and could lead to a better understanding of miscarriages.

La rotura del ADN ocurre en procesos naturales como la reparación del material genético. Investigadores del CNIO han congelado cerca de 200 estructuras biológicas para ilustrar esta reacción química, que dura microsegundos. Entender este mecanismo contribuirá a mejorar las herramientas biotecnológicas para tratar enfermedades genéticas.

Fossil from tiny plant eater, Aquilops americanus, suggests horned dinosaurs originated in Asia

The moon’s molten, churning core likely once generated a dynamo.

Taking the cancer drug tamoxifen for five years drives down the incidence of breast cancer in women at high risk for the disease by close to 30%, researchers have found. And the medication’s protective effects against breast cancer appear to last, unabated, for as long as 16 years after a woman stops taking it, a new study says.
