A walking molecule, so small that it cannot be observed directly with a microscope, has been recorded taking its first nanometer-sized steps. It's the first time that anyone has shown in real time that such a tiny object – termed a "small molecule walker" – has taken a series of steps.
Researchers have devised a way to replace the knee’s protective lining, called the meniscus, using a personalized 3D-printed implant, or scaffold, infused with human growth factors that prompt the body to regenerate the lining on its own. The therapy, successfully tested in sheep, could provide the first effective and long-lasting repair of damaged menisci.
An anomaly spotted at the Large Hadron Collider has prompted scientists to reconsider a mathematical description of the underlying physics. By considering two forces that are distinct in everyday life but unified under extreme conditions like those within the collider and just after the birth of the universe, they have simplified one description of the interactions of elementary particles.
Researchers have developed a new “high-entropy” metal alloy that has a higher strength-to-weight ratio than any other existing metal material. High-entropy alloys are materials that consist of five or more metals in approximately equal amounts.
Engineers at the University of California, San Diego have demonstrated a new and more efficient way to trap light, using a phenomenon called bound states in the continuum (BIC) that was first proposed in the early days of quantum wave mechanics.
The discovery of a new form of ice could lead to an improved understanding of our planet’s geology, potentially helping to unlock new solutions in the production, transportation and storage of energy. Ice XVI, the least dense of all known forms of ice, has a highly symmetric cage-like structure that can trap gaseous molecules to form compounds known as clathrates or gas hydrates.
Using a gene-editing system originally developed to delete specific genes, MIT researchers have now shown that they can reliably turn on any gene of their choosing in living cells.
Scientists have created an app that brings molecules to life in a handheld device. Through the app, people can use up to eleven fingers to examine in great detail more than 350 molecules.
Future fitness trackers could soon add blood-oxygen levels to the list of vital signs measured with new technology developed by engineers.
For the first time, scientists report the development of a stretchable “electronic skin” closely modeled after our own that can detect not just pressure, but also what direction it’s coming from.
Scientists are developing a new kind of “smart window” that can block out heat when the outside temperatures rise. The advance could one day help consumers better conserve energy on hot days and reduce electric bills.
The empty spacesuit that sat on the operating table in a lab at Houston Methodist Hospital's research institute made for an unusual patient.
Malaria parasites invade human red blood cells, which they bring to burst and infect others. Researchers at the University of Basel and the Swiss Tropical and Public Health Institute called nano imitations of host cell membranes have developed that deceive and trick the pathogen. This could lead to novel therapeutic and vaccine strategies against malaria and other infectious diseases.
As part of a project demonstrating new 3-D printing techniques, Princeton researchers have embedded tiny light-emitting diodes into a standard contact lens, allowing the device to project beams of colored light. The lens is not designed for actual use, though. Instead, the team created the device to demonstrate the ability to 3-D print electronics into complex shapes and materials.
Researchers at Rice University have created flexible, patterned sheets of multilayer graphene from a cheap polymer by burning it with a computer-controlled laser. The process works in air at room temperature and eliminates the need for hot furnaces and controlled environments, and it makes graphene that may be suitable for electronics or energy storage.
