21st Century Innovative Technologies and Developments as also discoveries, curiosity ( insolite)...

La cigarette électronique est devenue la principale alternative au tabac pour des millions de fumeurs dans le monde. Pourtant, elle n'en serait pas moins nocive. Selon une étude menée par des chercheurs de l'école de médecine de Stanford, le liquide qui permet d'aromatiser la vapeur des cigarettes électroniques pourrait augmenter le risque de maladies cardiovasculaires, la première cause de mortalité dans le monde, deuxième en France.

Les scientifiques ont étudié l'effet de ces e-liquides sur les cellules endothéliales. Ces cellules tapissent l'intérieur des vaisseaux sanguins et jouent un rôle essentiel dans la santé cardiaque et cardiovasculaire.

A new stick-on wearable sensor uses the symphony of internal rumblings, whooshing, gurglings, and cracklings to help doctors diagnose different conditions. And this souped-up, miniaturized stethoscope could one day be a way for clinicians to continuously monitor patients outside of the clinic. So far it’s been tested on chicken breasts and a very small group of people.

This wearable, smaller than a penny, can hear the beat of your heart, the sound of your voice, and even the whirr of an implantable heart pump, according to a paper published today in the journal Science Advances.

The need for heart transplants will always exceed the number of donor hearts available for transplant. Thanks to research just out from Massachusetts General Hospital, though, this may not continue to be a problem for much longer. Researchers there have just succeeded in growing fully contractile heart tissue by recellularizing a collagen scaffold, and they’re hoping to refine the method so that it can be used as a “functional myocardial patch” for cardiac injuries.

As reported by MIT Technology Review, the Pentagon developed the technology after a request was made by the US Special Forces. 

The Pentagon's device, known as Jetson, is able to tell us apart at a range of 200 meters and detects our unique cardiac signatures through an infrared laser. 

Jetson scans an area and is able to use what is known as "laser vibrometry" to detect changes on the surface of the skin caused by your heartbeat and the flow of blood.

Nature Materials, Harvard University researchers announced they’ve created the first 3D-printed heart-on-a-chip capable of collecting data about how reliably a heart is beating.

The printed organ is made of synthetic material designed to mimic the structure and function of native tissue. It is not designed to replace failing human organs, but it can be used for scientific studies, something that is expected to rapidly increase research on new medicine. The medical breakthrough may also allow scientists to rapidly design organs-on-chips to match specific disease properties or even a patient’s cells.
