Molecular machines are regarded as the next step in miniaturization. Their models can be found in living cells, where molecular motors convert energy and generate movement. Scientists have been working for decades to artificially ...
Human cells hold about two meters (6.6 feet) of DNA, folded and compacted to fit inside a nucleus. That packing is essential for life, but it creates a problem for scientists. Some of the genes that control a cell's identity ...
Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed a new class of light-activated compounds that could lead to safer and more versatile applications in 3D printing, cosmetics and medicine.
Applying eyedrops is difficult in space, where there is almost no gravity. A KAIST research team has developed a wearable patch that delivers eyedrops to the eye without relying on gravity. The research team was led by Professor ...
DNA is not randomly distributed within the nucleus but is packaged with proteins into chromatin, which is precisely folded into complex three-dimensional structures. However, scientists have not fully understood how this ...
When someone is badly injured, doctors urgently need two facts: the patient's blood type, so that a transfusion is safe, and their hematocrit, the share of the blood made up of red blood cells, which reveals blood loss or ...
Like the folds in crumpled sheets or the footprints on recently trodden sand, certain materials mark their histories. Now, Yale researchers show that networks of flowing water and other fluids can store their own memories—similar ...
Australian scientists have used high-speed video to uncover the unique mechanism that allows a honey bee's stinger to continue to pump venom into its target even after it has separated from the bee's body.
Light sheet microscopy allows biologists to selectively light up a thin slice of a sample. This method can improve image contrast by reducing background light while remaining gentle on the sample, reducing photodamage and ...
Research led by a group from the University of Newcastle has found a new way to make silicone surfaces—and control how slippery they are. The work was published in the journal Chemistry of Materials.
