Thirty years after scientists at the University of Missouri-Rolla and Grambling College discovered “strange” Xenon in meteorites, scientists from Japan and France are reporting the discovery of other strange elements left over from the birth of the solar system.
A 1976 study published in the journal Nature showed that strange Xenon, which is made in supernova explosions, is present within the composition of the Sun. Those findings by the UMR and Grambling team were largely dismissed. Now, in the March 31 issue of Nature, the Japanese and French team reports new evidence that the Sun has strange Oxygen, too.
“Elements are called ‘strange’ when the mix of atoms that comprise the element is unlike the mix of atoms that make up that element here on Earth,” explains UMR nuclear chemistry professor Dr. Oliver Manuel, who believes our solar system was created in a supernova blast. “Strange Xenon contains Xenon-136, which is made by rapid neutron capture in a supernova. Likewise, strange Oxygen has Oxygen-16, which is made by fusion inside a massive star.”

Scientists at the University of California, Los Angeles present new research on a curious cosmic phenomenon known as "whistlers" -- very low frequency packets...
Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.
When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...
Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur
What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...
