It's kind of a drag
Imagine walking from one side of a swimming pool to the other. Each step takes great effort -- that's what makes water aerobics such effective physical exercise.

Swimming microbots can remove pathogenic bacteria from water (video)
The lack of clean water in many areas around the world is a persistent, major public health problem. One day, tiny robots could help address this issue by zooming around contaminated water and cleaning up disease-causing bacteria. Scientists report a new development toward this goal in the journal ACS Applied Materials & Interfaces.

Micron-sized hydrogel cubes show highly efficient delivery of a potent anti-cancer drug
Researchers at the University of Alabama at Birmingham and Texas Tech University Health Sciences Center have developed micro-cubes that can sponge up a hydrophobic anti-cancer drug and deliver it to cancer cells. Tissue culture tests show these tiny, porous cubes, loaded with the hydrophobic drug, are more potent against liver cancer cells and less harmful to normal liver cells, compared to the drug alone.

Injectable plant-based nanoparticles delay tumor progression
The researchers discovered injecting potato virus particles into melanoma tumor sites activates an anti-tumor immune system response. And simultaneously injecting the nanoscale plant virus particles and a chemotherapy drug -- doxorubicin--into tumor sites further helps halt tumor progression in mice.

World first: New polymer goes for a walk when illuminated
Scientists have developed a new material that can undulate and therefore propel itself forward under the influence of light. To this end, they clamp a strip of this polymer material in a rectangular frame. When illuminated it goes for a walk all on its own. This small device, the size of a paperclip, is the world's first machine to convert light directly into walking, simply using one fixed light source. The researchers publish their findings in Nature.

Hacking the human brain -- lab-made synapses for artificial intelligence
One of the greatest challenges facing artificial intelligence development is understanding the human brain and figuring out how to mimic it. Now, one group reports in ACS Nano that they have developed an artificial synapse capable of simulating a fundamental function of our nervous system -- the release of inhibitory and stimulatory signals from the same 'pre-synaptic' terminal.

Cotton candy capillaries lead to circuit boards that dissolve when cooled
The silver nanowires are held together in the polymer so that they touch, and as long as the polymer doesn't dissolve, the nanowires will form a path to conduct electricity similar to the traces on a circuit board.

3-D-printed jars in ball-milling experiments
Mechanochemistry is a widespread synthesis technique in all areas of chemistry. Various materials have been synthesized by this technique when the classical wet chemistry route is not satisfactory. Characterization of the reaction mixture is however much less accessible than in solutions.

Moisture-responsive 'robots' crawl with no external power source
Using an off-the-shelf camera flash, researchers turned an ordinary sheet of graphene oxide into a material that bends when exposed to moisture. They then used this material to make a spider-like crawler and claw robot that move in response to changing humidity without the need for any external power.

Neuron-integrated nanotubes to repair nerve fibers
Carbon nanotubes exhibit interesting characteristics rendering them particularly suited to the construction of special hybrid devices -- consisting of biological issue and synthetic material -- planned to re-establish connections between nerve cells, for instance at spinal level, lost on account of lesions or trauma. This is the result of a piece of research published on the scientific journal Nanomedicine: Nanotechnology, Biology, and Medicine.

Thwarting metastasis by breaking cancer's legs with gold rods
Your cancer has metastasized. No one wants to ever hear that. Now researchers have developed a method to thwart cell migration and thus halt metastasis in vitro. In past tests in vivo, the treatment has wiped out tumors with no observable signs of toxicity or recurrence.

Research accelerates quest for quicker, longer-lasting electronics
In the world of electronics, where the quest is always for smaller and faster units with infinite battery life, topological insulators (TI) have tantalizing potential. In a paper published today in 'Science Advances,' Jing Shi, a professor of physics and astronomy at UC Riverside and colleagues MIT and Arizona State University report they have created a TI film just 25 atoms thick that adheres to an insulating magnetic film, creating a 'heterostructure.'

Holey pattern boosts coherence of nanomechanical membrane vibrations
Researchers at the Niels Bohr Institute have introduced a new type of nanomechanical resonator, in which a pattern of holes localizes vibrations to a small region in a 30 nm thick membrane. The pattern dramatically suppresses coupling to random fluctuations in the environment, boosting the vibrations' coherence. The researchers' quantitative understanding and numerical models provide a versatile blueprint for ultracoherent nanomechanical devices. Among others, this enables a new generation of nanomechanical sensors to probe quantum limits of mechanical measurements, and more sensitive force microscopy.

Smooth propagation of spin waves using gold
Assistant Professor Taichi Goto at Toyohashi University of Technology elucidated the noise generation mechanism of the spin wave (SW), the wave of a magnetic moment transmitted through magnetic oxide, and established a way to suppress it. The large noise generated by SWs traveling through magnetic oxides has presented a significant obstacle to its applications. However, it became clear that noise can be suppressed by installing a thin gold film in the appropriate places.

Drip by drip
How do crystals grow? The answer given in current textbooks is: Layer by layer atoms or molecules settle on an existing crystal surface. The research team Physical Chemistry at the University of Konstanz has now observed a preliminary stage of this crystal growth in glutamic acid that contradicts this classical principal of growth. Not individual atoms settle on an existing crystal surface, but nano-drips that already contain building blocks for growth.
