This is a transistor, but not as you know it. Instead of acting as a tiny switch to control the flow of electrons, this devices controls the flow of living cells.
The Y chromosome, a chunk of genetic code that is unique to male mammals, isn’t just physically smaller than the X. It also contains far fewer genes. The X has more than 1000 genes, while the Y has fewer than 200 —and most of them don’t even work. Why do men have this odd, stunted chromosome in their genomes?
If you’ve ever felt like your life’s turned on its head, be thankful that you’re not this little embryo—which turns itself inside out.
We all grow from small bunch of cells into fully-fledged adults, but rarely do we get to see the process in action. In this video, researchers have peered into a mouse kidney, to watch how cells branch out to form the organ's internal pipework.
It's like wearing X-ray goggles, but better. Caltech researchers have created two new techniques that allow them to identify individual cells within 3D, intact organisms or tissues. And the results are jaw-droppingly beautiful.
Andy Lomas made this music video for a song called Seething by Max Cooper. Lomas created software that emulates biological cell growth. Just by adjusting certain parameters, such as the forces between cells or the source and quantity of nutrients, he obtains different forms.
Staying healthy is a lot like medieval warfare. Cells vs viruses. There are cells defending their castles and viruses trying to break through. If a sneaky virus manages to attack a cell, the cell fights it and notifies all the other castles about what to build to defend it. Man, learning about biology is so much…
To get a super-detailed X-ray view inside a cell—right down to the individual molecules—scientists dunk the cell they're looking at in preservative chemicals. That not only kills the cell, it changes its internal structure ever so slightly, meaning researchers aren't getting an exact look at the cell's natural state.…
Scientists have long been toiling to create artificial life, managing to produce man-made cell walls and even synthetic DNA. But now, a team of chemists has produced a functioning cell made from polymers.
Every year, GE Healthcare runs a competition to find the best microscopic cell images of the year—and here are some of our favorites from the shortlist.
You might think 30 seconds is pretty short. Your body doesn't though. In order to keep everything running, there's a lot of things going on in those 30 seconds. Like you'll make 72 million red blood cells! And shed 174,000 skin cells! And have 25 thoughts. The human body, what a wonderful thing. [BuzzFeed Video]
This isn't a cartoon tree or some strange piece of modern art. In fact, it's what researchers from the University of Texas at Austin saw when they managed to observe a virus in the act of penetrating a cell.
You've probably got a cell phone in your pocket, but a new discovery by Swiss researches could put one under your skin. By modifying cells' reaction to certain genes and enzymes, the researchers were able to make them communicate and exchange information. Kind of like if they were on the phone. You know, a cell phone.
Researchers at Johns Hopkins have discovered an efficient and totally safe method to turn adult blood cells "all the way back to the way [they were] when that person was a 6-day-old embryo." The discovery could be the key to cure the incurable—from heart attacks to severed spinal cord to cancer—and open the door, some…
The biological cell is an extremely advanced microscopic entity that can look after itself, but it's not exactly what you'd call smart. That's all about to change, though, because scientists are now making cells that can perform arithmetic—and the next stop stop is a living implant that can act as a computer.
In recent court filings, the Food and Drug Administration has asserted that stem cells—you know, the ones our bodies produce naturally—are in fact drugs and subject to its regulatory oversight. So does that make me a controlled substance?
