Spermbots

A team in Germany has developed tiny robot suits that can help sperm become more mobile, solving one of the biggest causes of infertility in men. If the researchers can successfully replicate their lab results inside the human body, it could be a new option for couples struggling to conceive.

These 'spermbots' are miniature metal helixes just large enough to completely wrap around the tail of a single sperm and help it along its way towards the egg. The bots are powered with the assistance of a magnetic field controlled by the scientists, though all of the experiments undertaken so far have been with bull sperm in the confines of a petri dish. Once the sperm has reached its target and become embedded in the egg, the metal casing can reverse direction to detach itself.

Un equipo de Alemania ha desarrollado diminutos robots que pueden ayudar a los espermatozoides a ser más móviles, la solución de uno de los mayores causas de infertilidad en los hombres. Si los investigadores pueden replicar con éxito sus resultados de laboratorio en el interior del cuerpo humano, podría ser una nueva opción para las parejas que luchan por concebir.

Estos ''espermabots" son hélices metálicas en miniatura lo suficientemente grandes como para envolver completamente alrededor de la cola de un solo espermatozoide y ayudar a que a lo largo de su camino hacia el óvulo. Los bots son alimentados con la ayuda de un campo magnético controlado por los científicos, a pesar de todos los experimentos realizados hasta el momento se ha estado experimentando con esperma de toro en una placa de Petri. Una vez que el esperma ha llegado a su destino y se incrustan en el huevo, la carcasa de metal se puede invertir el sentido  y separarse.

Researchers have developed a new kind of synthetic creature, using the heart cells of a rat to make a robotic stingray that follows light.

Created by bioengineer Kit Parker from the Wyss Institute at Harvard University. 
The cyborg stingray, which weighs just 10 grams and is only about the size of a small coin, is made from a gold skeleton overlaid with a thin layer of stretchy polymer. This body, designed to emulate the shape and fins of a real ray, is coated in approximately 200,000 living rat heart cells, called cardiomyocytes.

These muscle cells were genetically engineered to respond to light cues, to prompt the fin movements that help propel the robot through water. When stimulated by light, the cardiomyocytes contract and push the fins downwards.

Counting CFU (Colony-Forming Units) is a really tedious and error prone routine during biological experiments. To address this, MediXgraph developed an App (CFU Scope) which can accurately calculate the number of colonies in an agar plate. It usually takes several minutes to count one plate manually. With this App, it can be done automatically within 3 seconds. This can saves a lot of time for personnel in biological labs.
Download the app: http://medixgraph.com/cfuscope_mobile

Contar UFC (unidades formadoras de colonias) es una rutina muy tediosa y es una actividad propensa a errores durante los experimentos biológicos. Para solucionar esto, MediXgraph desarrolló una (Alcance CFU) App que puede calcular con precisión el número de colonias en una placa de agar. Por lo general toma varios minutos para contar una placa de forma manual. Con esta aplicación, se puede hacer de forma automática en aproximadamente 3 segundos. Esto puede ahorrar mucho tiempo para el personal de laboratorios biológicos.
