Heart tissue is unable to repair itself after a heart attack because heart cells cannot multiply and cardiac muscles contain few stem cells. Now, researchers are literally setting a new gold standard in cardiac tissue engineering.
Scientists have designed a first-ever experiment for demonstrating quantum entanglement in the macroscopic realm. Unlike other such proposals, the experiment is relatively easy to set up and run with existing semiconductor devices.
Electrical engineers have demonstrated a new kind of building block for digital integrated circuits. Their experiments show that future computer chips could be based on three-dimensional arrangements of nanometer-scale magnets instead of transistors.
Researchers have synthesized crystalline materials that can bind and store oxygen in high concentrations. Just one spoon of the substance is enough to absorb all the oxygen in a room. The stored oxygen can be released again when and where it is needed.
In this animation you can see how metastasis and angiogenesis occur. Metastasis, or metastatic disease, is the spread of a cancer from one organ to another. This is first animation from series about oncology and cancer genesis.
In popular culture, mathematics is often deemed inaccessible or esoteric. Yet in the modern world, it plays an ever more important role in our daily lives and a decisive role in the discovery and development of new ideas - often behind the scenes.
In a rare case of having their cake and eating it too, scientists have developed a toolset that allows them to explore the complex interior of tiny, multi-layered batteries they devised. It provides insight into the batteries' performance without destroying them.
Tractor beam technology, if it were to exist, would be based on waves that go in the opposite direction, converging from out in space onto the point of origin. Researchers now showed that the idea may not be all science fiction.
