The best part of high school biology was the movies. Some of them basically amounted to weird close-up fetish porn, sure. Other high school biology videos were actually educational, including the only one that ever taught me anything about the human cell, Inner Life of a Cell. But a new video puts them all to shame.
A new microscope developed at the Marine Biological Laboratory in Woods Hole, Massachusetts is allowing scientists track the position and orientation of individual molecules in living cells. It has the potential to reveal unknown aspects of molecular behavior, including those that turn cells into agents of disease.
Using state-of-the art microscopy, scientists have peered inside cardiac cells while they beat, revealing tube-like structures that buckle and then snap back into shape, much like shock absorbers. The details now appear in Science.
Scientists from China have made history by taking a cell that’s not a sperm cell and then used it to create a live animal. A similar technique could be used one day to treat infertility in humans.
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.
For the first time ever, molecular biologists have filmed the death of a human white blood cell. But the video shows something else, too. These integral components of our immune system do not go quietly into that good night. Rather, they go down alerting their neighbors to the presence of potential pathogens.
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 from Penn State University have just taken us a major step closer to a Fantastic Voyage future. For the first time ever, researchers have controlled the movements of living cells by inserting tiny synthetic motors directly inside them.
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.
Scientists have discovered why cancer cells spread around a human body: They actually chase down healthy cells trying to escape. "Researchers are confident that some cancers work according to this chase-and-run principle," io9.com reports. "Healthy cells try to escape from tumor cells, only to be followed around the…
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]
