Scientists at Tokyo Institute of Technology (Tokyo Tech) have recently developed a fully scalable method for the synthesis of atom-precise platinum clusters for potential use in catalytic applications. This method could provide a new pathway for large-scale production of atom-precise clusters. To demonstrate this, the hydrogenation of styrene was performed.
A study conducted by researchers in Brazil shows patients with chronic migraine are three times as likely to suffer from severe temporomandibular disorder. Though not a primary cause, the disorder is thought to accentuate and perpetuate sensitivity to pain; therefore, researchers recommend in chronic migraine clinical practice the assessement of the disorder's symptoms.
Efforts to remove barriers to accessing emergency contraception (EC) scored victories in 2013, when the US Food and Drug Administration removed age restrictions on over-the-counter sales of the levonogestrel drug Plan B.
While it is known that pearls are made of calcium carbonate with an organic matrix core, the role of the proteins modulating the organization of these crystals has, until recently, been unclear. Researchers at NYU Dentistry reported the role of two such proteins that regulate the processes leading up to the formation of pearl.
A 50-year-old debate has at last been settled: the highest-energy cosmic rays do not originate in our own Galaxy but in galaxies located tens or even hundreds of millions of light years away. The evidence comes from the Pierre Auger Observatory in Argentina, which has been gathering data since 2004 about these particles that constantly bombard the Earth. The CNRS is the observatory's principal French funding agency.
Fifty years ago, scientists discovered that the Earth is occasionally hit by cosmic rays of enormous energies. Since then, they have argued about the source of those ultra-high energy cosmic rays -- whether they came from our galaxy or outside the Milky Way. The answer is a galaxy or galaxies far, far away, according to a report published Sept. 22 in Science by the Pierre Auger Collaboration.
When a nitrogen atom is next to the space vacated by a carbon atom, it forms what is called a nitrogen-vacancy center. Now, researchers have shown how they can create more NV centers, which makes sensing magnetic fields easier, using a relatively simple method that can be done in many labs. They describe their results this week in Applied Physics Letters.
When the strong winds that circle the Arctic slacken, cold polar air can escape and cause extreme winter chills in parts of the Northern hemisphere. A new study finds that these weak states have become more persistent over the past four decades and can be linked to cold winters in Russia and Europe.
Scientists confirm that the age and content of an old sack is in accordance with a medieval myth about Saint Francis of Assisi.
according to scientists from Aalto University Finland, viruses and nanoparticles can be assembled into processable superlattice wires. The demonstration shows that electrostatic self-assembly of nanoparticles can potentially be used to form processable materials for future applications.
