Bubble technology invented that can shoot drugs deep into tumors

Using ultrasound, drug particles can be directed to a specific area, including tumors, researchers report. They have created micro-sized gas bubbles coated with cancer drug particles and iron oxide nanoparticles, and then use magnets to direct these bubbles to gather around a specific tumor.

NTU scientists invent bubble technology which can shoot drugs deep into tumors

Scientists at Nanyang Technological University (NTU Singapore) have invented a new way to deliver cancer drugs deep into tumour cells. The NTU scientists create micro-sized gas bubbles coated with cancer drug particles and iron oxide...Show More Summary

In these microbes, iron works like oxygen

New light has been shed on a curious group of bacteria that use iron in much the same way that animals use oxygen: to soak up electrons during biochemical reactions. When organisms -- whether bacteria or animal -- oxidize carbohydrates, electrons must go somewhere.

Mysterious 'four-dimensional' iron oxide explained

An international group of researchers including Russian scientists from the Moscow State University has been studying the behaviour of the recently-discovered Fe4O5, iron oxide. The group has succeeded in describing its complex structure, and proposed an explanation for its very unusual properties. Show More Summary

Extreme Micro-Organisms Discovered Replacing Oxygen With Iron Oxide --"Foreshadows Life On Other Worlds"

“A fundamental approach in astrobiology is to use terrestrial sites as analogs, where we look for insight into the possibilities on other worlds,” says Eric Roden, a professor of geoscience at University of Wisconsin–Madison. “Some people believe that use of...

Magnetic nanoparticles show promise in biomedical applications

Recent developments and research related to iron oxide nanoparticles confirm their potential in biomedical applications – such as targeted drug delivery – and the necessity for further studies.

How to Create a Rusted Metal Text Effect in Adobe Photoshop

What You'll Be Creating Rusted metal is one of those natural phenomena that is terribly destructive, yet strangely beautiful at the same time. As iron ore oxidizes it creates brilliant colors, patterns and texture in a surface we normally expect to be smooth and plain. Show More Summary

Discovery of new iron oxides points to large oxygen source inside the Earth

Using a special high-pressure chamber, scientists have discovered two new iron oxides in experiments at DESY's X-ray light source PETRA III and other facilities. The discovery points to a huge, hitherto unknown oxygen source in the lower mantle of the Earth. Show More Summary

Iron Oxide Nanoparticles Reduce Oxidative Stress in Flies

3 months agoHealth / Aging : Fight Aging

Researchers have found that iron oxide nanoparticles can act in similar ways to cellular antioxidants such as catalase, soaking up oxidative molecules and reducing oxidative stress and consequent damage. To the degree that this helps...Show More Summary

Dimensionality transition in a newly created material

Iron oxides occur in nature in many forms, often significantly different from each other in terms of structure and physical properties. However, a new variety of iron oxide, recently created and tested by scientists in Cracow, surprised both physicists and engineers, as it revealed features previously unobserved in any other material. read more

Japanese scientists create super-strong glass, but don't call it 'unbreakable'

Rumors of a truly unbreakable glass breakthrough are greatly exaggerated. In late October, scientists in Japan revealed that they had successfully developed a new form of oxide glass that is as strong as cast iron and, by one metric,...Show More Summary

Exploding Thermite Pumpkins

6 months agoHumor / odd : Neatorama

A video from The Royal Institution explains in a very calm, subdued, British way what happens when you burn iron oxide and aluminum powder inside a pumpkin. The visual effects are quite impressive. (YouTube link) It’s also quite dangerous, so don’t try this at home. Please. Thermite is nothing to fool around with. -via The Daily Dot

Two Jack-o’-Lanterns Demonstrate an Explosive Thermite Reaction in a Fiery Halloween Science Video

6 months agoHumor / odd : Laughing Squid

Two jack-o’-lanterns demonstrate an explosive thermite reaction in a fiery halloween science video by the Royal Institution of Great Britain. Host Andy Marmery explains the powerful exothermic reaction between iron oxide and aluminum powders that erupts and sets off a wad of gun cotton in the second pumpkin.

Create Your Own Rust Brushes From Scratch in Adobe Photoshop

What You'll Be Creating Rust. That beautifully terrible oxidation of iron elements. It's a fact of life in our world filled with metal and machines. Time and moisture take their toll, and even our most magnificent machines deteriorate. Show More Summary

Platinum and iron oxide working together get the job done

Using pictures with atomic resolution, the mechanism of an important chemical reaction has finally be explained: When platinum nanoparticles act as catalysts on an iron oxide surface, the surface plays a crucial role.

Kabuno Bay's Iron Oxidizing Bacteria Give Clues to Earth's Archean and Proterozoic Oceans

An isolated, iron-rich bay in the heart of East Africa is offering scientists a rare glimpse back into Earth's primitive marine environment, and supports theories that tiny microbes created some of the world's largest ore deposits billions...Show More Summary

What’s Inside Caladryl Will Not Make You Hallucinate

Itch-relieving action for the summer starts with this eponymous pink stuff, a cocktail of zinc oxide and a little iron oxide. The post What’s Inside Caladryl Will Not Make You Hallucinate appeared first on WIRED.

C. difficile needs iron, but not too much: Insights into maintaining it 'just right'

Those bacteria that require iron walk a tightrope. Iron is essential for their growth, but too much iron can damage DNA and enzymes through oxidation. Therefore, bacteria have machinery to maintain their intracellular iron within a range that is healthy for them, scientists report.
