Nanoparticles make turkey eggs microbe-resistant

Australian brush turkeys incubate their eggs in places most animals would stay clear of: moist piles of rotting vegetation. There are some advantages to this approach, most notably that the heat released by the microbes keeps the eggs warm but those same microbes can also get through eggshells and kill the embryos. However, even though the risks […]

DNA nanobots deliver drugs in living cockroaches – it’s a computer, inside a cockroach

The future is here. Nano-sized entities made of DNA that are able to perform the same kind of logic operations as a silicon-based computer have been introduced into a living animal. It’s every Science Fiction fan’s dream come true. The tiny DNA computers are called origami robots, because they work by folding and unfolding strands of DNA; […]

Stitches to become a thing of the past? Doctors to use polymer nanofibers to promote healing

Throughout the world, tens of millions of people get stitches every year, and researchers have been looking for better options for quite a while. Now, a team of Maryland researchers proposed applying sticky, biodegradable mats of polymer nanofibers onto surgical incisions to seal them and promote healing. This is not a new idea, but the […]

Sending a text message using Vodka molecules – the first continuous molecular communication

In nature, organisms communicate in various ways, be it through acoustic or biological signals. Insects, for instance, communicate and relay important information, such as a threat to a hive, using pheromones – an excreted chemical with a particular signature. Scientists at the University of Warwick in the UK and the York University in Canada have […]

Creating the smallest Mona Lisa – just 30 microns across

Mona Lisa is probably the most well known picture in the world – it’s been painted thousands of times, inspired countless artists, and her enigmatic smile still puzzles researchers and artists alike; but never before has it been painted on such a small canvas. Demonstrating a very potent nanotechnique, researchers have made a miniature Mona Lisa […]

Graphene is still the world’s most powerful material – even when it’s flawed

In terms of materials, graphene is definitely the hot cherry at the moment; it is basically a one-atom thick layer of the mineral graphite (carbon), with more such layers stacked together forming crystalline graphene. It is very light, with a 1-square-meter sheet weighing only 0.77 milligrams, but also very durable and has a number of […]

Developing a new type of glue

Over the past decades, what we mean by glue has changed significantly; techniques have emerged, materials have been developed, and one of the most viable candidates for a superglue is gold. Researchers have found numerous applications for attaching molecules to gold; the approach uses chemicals called thiols to bind the materials together. But while this […]

Creating glasses that don’t fog up

Creating glasses that don’t fog or freeze up could not only bring a world of comfort to millions of people, but it could also have a myriad of applications in cameras, microscopes, mirrors and refrigerated displays – to name just a few. While there have been many advancements in this field, so far, the main problem […]

Cicada wing destroys bacteria solely through its physical structure

The veined wing of the clanger cicada kills bacteria is able to destroy bacteria by its structure alone – one of the first structures ever found that can do this. The clanger cicada is an insects that looks like something between a fly and a locust; its wings are covered with a vast hexagonal array […]

New nanotechnology will enable earlier cancer diagnosis

Finding ways to diagnose cancer earlier could potentially save millions of lives, improving the chances of survival for many patients. This is why researchers have developed nanoparticles which amplify tumor signals, making them much easier to detect. Nanotech to the rescue The new technology was developed by researchers from MIT and it makes biomarker detection […]
