A team at Harvard’s Wyss Institute for Biologically Inspired Engineering demonstrated the latest advances in programmable DNA self-assembly by crystallizing 32 structures with precisely prescribed depths and complex 3D features. The DNA crystals could potentially be used as the basis of a programmable material platform that would allow scientists to build extremely precise and complex structures rivaling the complexity of…

Underwater glue inspired by shellfish might help repair ships

strongest underwater glue

Taking inspiration from nature, scientists at MIT have engineered a new sort of glue that acts like a powerful adhesive even in underwater conditions and can cling on to virtually any surface, be it metal or organic. The glue might prove to be useful to repair ships or seal wounds and surgical incisions. The strongest underwater glue to date Shellfish…

The Hagfish produces a 12 nanometer wide, 15 centimeter long thread it clamps into a single cell

Nested-Conical-Arrangements-LONI-1

When it feels threatened, the hagfish produces a slime which is only 12 nanometers wide, but 15 centimeters long – 10,000,000 times longer than it is wide. It’s not clear exactly what this slime is made of (likely a sugar modification), but its purpose is to make the hagfish slippery and possibly clog the gills of a predator. The thread is clamped into…

From atoms to life size: manufacturing from nanoscale up to macro

Image: DARPA

DARPA just announced the launch of a new extremely exciting program: Atoms to Product (A2P). The aim is to develop a suit of technologies that will allow manufacturing of products from the nanoscale up to what we know as ‘life size’. The revolutionary miniaturization and assembly methods would work at scales 100,000 times smaller than current state-of-the-art technology. If found successful, then DARPA…

Programmed to Fold: RNA Origami

Rothemund-RNA-Tiles-Assembling-in-Solution_NEWS-WEB

A team of researchers from the Aarhus University in Denmark and CalTech has developed an origami-inspired method of organizing molecules on the nanoscale. The team has modeled RNA, DNA’s close cousin into complicated shapes using the technique. Together with DNA, RNA comprises the nucleic acids, which, along with proteins, constitute the three major macromolecules essential for all known forms of life….

This bacterium shoots wires out of its body to power itself

nanowire%20bacteria

This bacterium has a lot in common with power companies. Power companies use copper wires to channel electricity (and therefore, electrons), and this bacterium developed a mechanism to do something similar: in the absence of oxygen, it grows nanowires from its own body through which it pushes electrons to nearby rocks. This is how it obtains energy, as opposed to…

A component from scorpion and honeybee venom stops cancer growth

1408134617718

The difference between a poison and a cure is the dosage – and this could be very well said about this approach. Bio-engineers report that peptides in some venoms bind to cancer cells and block tumor growth and spread and could be effectively used to fight cancer – the only problem is they might also harm healthy cells. Bioengineer Dipanjan…

Brighter and cheaper LEDs could be made from perovskite

perovskite_led

We’ve covered quite a bit the recent developments involving perovskite as an extremely promising light-to-energy conversion semiconductor. Now, researchers at University of Cambridge, University of Oxford, and Ludwig-Maximilians-Universität are performing research on perovskite-based devices that work the other way around by emitting light. Their research has turned out promising results that suggest high-brightness LEDs, manufactured at low cost and more easily,…

Organ on a chip might end animal testing and improve drug research

organ-on-a-chip

Here at ZME Science we often report on cutting edge developments and various medical breakthroughs that offer novel treatments and such. Most of these drugs or techniques are first studied on animal models, and while they hold great promise, it’s most often than not that the desired response isn’t replicated in humans. This translates in millions flushed down the drain…
