These 3D images are our first ever look at how DNA shapes itself inside cells

For the first time, scientists have been able to model the physical structure of mammalian genomes from individual cells, giving us a unique 3D perspective on how DNA packages itself inside our cells.

Through the new technique, scientists can see how the arrangement of cell chromosomes (DNA strands) are designed to keep some cells active or inactive at any one time.

Bill Nye: Evolution Denial Hurts Innovation in Science and Technology - Video

Bill Nye:  Evolution is the fundamental idea in all of life science. So if we raise a generation of science students who don’t understand the main idea in biology they’re going to be incompletely educated students and this is going to be trouble for the United States because the United States keeps in the game economically by innovating – having new ideas, new products, new ways of doing things. That’s what the United States produces and brings to the world. And if we raise a significant fraction of our students who don’t understand...

First human-pig 'chimera' created in milestone study | Science

Scientists have created a human-pig hybrid in a milestone study that raises the prospect of being able to grow human organs inside animals for use in transplants.

It marks the first time that embryos combining two large, distantly-related species have been produced. The creation of this so-called chimera – named after the cross-species beast of Greek mythology – has been hailed as a significant first step towards generating human hearts, livers and kidneys from scratch.

Is Your Red The Same as My Red?

It’s a question that everyone has pondered at one time or another: does everyone view colors in the same way? Of course, there are people with color blindness and other disorders that do skew their perception of color. But among the rest of us with normal color vision, can we ever be sure we’re seeing exactly the same thing?

In this video from Vsauce, Michael investigates this very question in addition to other...

WATCH: Incredible deep Sea Creatures that look like Aliens

The deep sea is the lowest layer of the ocean, at a depth of 1800m or more. Little or no light penetrates so deep; it was therefore thought historically that no life would be found there. But on the contrary, sea life thrives in the deep sea and their world looks more like an alien planet.
