Spinach and Nanodiamonds? New Biosensor Can Finally Detect Ironlevel in Blood Accurately

Lack of iron—caused by malnutrition—can lead to anemia while an increased level of iron may signal the presence of an acute inflammatory response. Therefore, the blood iron level is an important medical diagnostic agent.

Protons Jump Between Water Molecules Differently Than Thought for 200 Years

Protons, as positively charged hydrogen ions, move very rapidly in water from one water molecule to the next, which is why the conductivity of water is relatively high. The principle of proton conduction in water has been known for 200 years and is named the Grotthuss mechanism after its discoverer,...

Physicists Discover Shape-Shifting Particles: Muon Neutrinos Transform

It's a new breakthrough when it comes to particle physics. Scientists have made the first definitive observation of the transformation of muon neutrinos to electron neutrinos. This type of neutrino oscillation has never been seen before and could help researchers explore a fundamental question of sc...

Scientists Create a Surfer's Dream: A 'Frozen' Wave in a New Experiment (Video)

It's every surfer's dream: a wave that never breaks and essentially remains "frozen" in time. Now, researchers have created this wave in a laboratory. The new discovery could lead to improvements in boat and seaport designs as well as enable the analysis of how carbon dioxide exchange between the oc...

New LHC Discovery Impacts Physicists' Hunt for Dark Matter

As scientists continue to search for dark matter in the universe, researchers have made some surprising new discoveries. CERN has announced that scientists on two separate Large Hadron Collider experiments have succeeded in measuring one of the rarest measurable processes in physics, the decay of B-...

World's Slowest-Moving Tar Pitch Drop Caught on Camera (Video)

Tar pitch is thick and viscous, appearing to be almost solid as it slowly oozes. About 69 years ago, scientists set up a pitch-drop experiment to test exactly how long it would take for a single piece of the black substance to fall into a beaker. Now the experiment is finally over--the researchers h...

How to Unlock the Secrets of DNA With High-Throughput Computing

The binding power of DNA is well known – bases, bound into complementary pairs, are the building blocks of its double helix structure. Short sequences of DNA (15 to 40 base pairs in length) also chemically bond to small nanoparticles.

Acoustic Levitation: The Power of Sound Makes Objects Float (Video)

Ever wanted to make an object float? You don't need magic; you just need science. Researchers have used the power of sound to levitate objects and even move them around in midair. The findings could have huge implications for manufacturing processes, but are also just plain cool.

New Form of Carbon Synthesized: Grossly Warped 'Nanographene'

This new material consists of many identical piece of grossly warped graphene, each containing exactly 80 carbon atoms joined together in a network of 26 rings, with 30 hydrogen atoms decorating the rim. These individual molecules, because they measure somewhat more than a nanometer across, are ref...
