A new paper from the University of Surrey and the University of Cambridge has detailed how two relatively unexplored semiconducting materials can satisfy the telecommunication industry’s hunger for enormous amounts of data at ever-greater speeds.

Light-emitting diode (LED)-based communications techniques allow computing devices, including mobile phones, to communicate with one another by using infrared light. However, LED techniques are underused because in its current state LED transmits data at far slower speeds than other wireless technologies such as light-fidelity (Li-Fi).

In a paper published by Nature Electronics, the researchers from Surrey and Cambridge, along with partners from the University of Electronic Science and Technology of China, examine how organic semicond...

Using a supercomputer simulation, a research team at Lund University in Sweden has succeeded in following the development of a galaxy over a span of 13.8 billion years. The study shows how, due to interstellar frontal collisions, young and chaotic galaxies over time mature into spiral galaxies such as the Milky Way.

Soon after the Big Bang 13.8 billion years ago, the Universe was an unruly place. Galaxies constantly collided. Stars formed at an enormous rate inside gigantic gas clouds. However, after a few billion years of intergalactic chaos, the unruly, embryonic galaxies became more stable and over time matured into well-ordered spiral galaxies...

Heart attacks and strokes are the main causes of death and loss of productive years globally. These clinical complications are caused by atherosclerosis, which is a chronic disease that leads to the accumulation of LDL cholesterol and immune cells in the inner layer of arteries and thereby resulting in the build-up of atherosclerotic plaques. Researchers from the Department of Laboratory Medicine of the Medical University of Vienna in collaboration with colleagues from the University of Lausanne (Switzerland) and the University of Cambridge (UK) have identified that a cytokine called A Proliferation Inducing Ligand (APRIL) plays a major protective role against the formation of atherosclerotic plaques. The study was now published in the journal Nature.

The investigators found that g...

Scientists at Nanyang Technological University, Singapore (NTU Singapore) have found a way to use sunflower pollen to develop a 3D printing ink material that could be used to fabricate parts useful for tissue engineering, toxicity testing and drug delivery.

This pollen-derived ink is able to hold its shape when deposited onto a surface, making it a viable alternative to current inks used for 3D printing in the biomedical field (also known as bioprinting). Such inks are usually soft and delicate, making it a challenge to retain the final product’s desired 3D shape and structure as the bioprinter deposits the ink layer by layer.

To illustrate th...
