Scientists Unveil First-Ever Images of a Cell Building Its ‘Molecular Highway’

Posted by in categories: biotech/medical, innovation

A team of researchers in Spain has achieved a breakthrough by capturing the world’s first detailed images of a human cell’s ‘highway network’ beginning to emerge.

The high-resolution images and atomic-scale film help explain a longstanding puzzle of how small structures called microtubules form during cell division. The discovery could progress the development of targeted treatments for cancer, and many other conditions.

Endovascular thrombectomy found to be beneficial for large ischemic stroke

Posted by in categories: biotech/medical, neuroscience

For patients with acute ischemic stroke and large cores, endovascular thrombectomy (EVT) improves clinical outcomes compared with medical management (MM), according to a study published online Feb. 7 in the Journal of the American Medical Association to coincide with the annual American Stroke Association International Stroke Conference, which was held from Feb. 7 to 9 in Phoenix.

Amrou Sarraj, M.D., from Case Western Reserve University in Cleveland, and colleagues describe the relationship between imaging estimates of irreversibly injured brain and at-risk regions and and EVT treatment effect in an exploratory analysis of the SELECT2 trial.

Adults with due to occlusion of the internal carotid or (M1 segment) and large ischemic core were randomly allocated to EVT versus MM across 31 global centers; the analysis included 336 patients.

The Limits of Immortality & Digital Death

Posted by in categories: biotech/medical, life extension

It is often thought that if we cure aging or find out how to upload a human mind that humans will be immortal. Today we will examine that notion and see how well it holds up against astronomical time lines.

Frog embryo study helps scientists unravel the human birth anomaly of intestinal malrotation

Posted by in category: biotech/medical

How does our intestine, which can be at least 15 feet long, fit properly inside our bodies? As our digestive system grows, the gut tube goes through a series of dramatic looping and rotation to package the lengthening intestine. Failure of the gut to rotate properly during development results in a prevalent, but poorly understood, birth anomaly called intestinal malrotation.

Now, in a study published in the journal Development, scientists from North Carolina State University have uncovered a potential cause of this life-threatening condition.

Intestinal malrotation affects 1 in 500 births but the underlying causes are not well understood. To find out why gut revolution could go amiss, scientists need to first understand intestinal rotation during normal development, a complex process that still baffles biologists.
