Study says Natives most affected by Amazon mercury
A study of mercury contamination from rampant informal gold mining in Peru's Amazon says indigenous people who get their protein mostly from fish are the most affected, particularly their children.
Engineers make golden breakthrough to improve electronic devices
(Phys.org) —A Kansas State University chemical engineer has discovered that a new member of the ultrathin materials family has great potential to improve electronic and thermal devices.
Separate teams develop similar method for creating non-oxidizing silver nanoparticles
Nanostructures made of DNA strands can encapsulate, release small-molecule drugs
Nanoscale "cages" made from strands of DNA can encapsulate small-molecule drugs and release them in response to a specific stimulus, McGill University researchers report in a new study.
Reproducing nature's chemistry: Researchers alter molecular properties in a new way
In their search for molecules with certain characteristics, chemists have produced millions of new, increasingly complex synthetic materials by altering molecules' chemical structures.
Researchers figure out why gold nanoparticles can penetrate cell walls
Cells are very good at protecting their precious contents—and as a result, it's very difficult to penetrate their membrane walls to deliver drugs, nutrients or biosensors without damaging or destroying the cell. One effective ...
Bubbles are the new lenses for nanoscale light beams
Bending light beams to your whim sounds like a job for a wizard or an a complex array of bulky mirrors, lenses and prisms, but a few tiny liquid bubbles may be all that is necessary to open the doors for ...
Using X-ray vision to detect unseen gold
Powerful X-rays can now be used to rapidly and accurately detect gold in ore samples, thanks to a new technique developed by CSIRO – a move that could save Australia's minerals industry hundreds of millions ...
Calibrators from deep space tune high-tech earthbound physics experiments
Hold out your hand: Look closely. If you're outside on a sunny day, you might see dust motes and pollen dance in the air, perhaps landing on your skin, and bright rays of sunlight peek between your fingers. ...
Eucalyptus macrocarpa is giving nano-medicine a boost
(Phys.org) —Murdoch University researchers have developed a 'green' method to create antibacterial gold nanoparticles for potential use in the medical field with the help of common eucalyptus leaves.
Using gold and light to study molecules in water
Thanks to a new device that is the size of a human hair, it is now possible to detect molecules in a liquid solution and observe their interactions. This is of major interest for the scientific community, ...
Insect-inspired super rubber moves toward practical uses in medicine
The remarkable, rubber-like protein that enables dragonflies, grasshoppers and other insects to flap their wings, jump and chirp has major potential uses in medicine, scientists conclude in an article in ...
Gold nanoparticles improve photodetector performance
The mineral molybdenum disulfide (MoS2), which, when solid, behaves in many ways like grease, has semiconducting properties that make it a promising alternative to silicon or graphene in electronic devices. It also strongly ...
Ancient technology for metal coatings 2,000 years ago can't be matched even today
Artists and craftsmen more than 2,000 years ago developed thin-film coating technology unrivaled even by today's standards for producing DVDs, solar cells, electronic devices and other products. Understanding these sophisticated ...
