AMES, Iowa – Three Iowa State University physicists have spent the past decade helping to upgrade hardware and untangle messy proton-proton collisions at the Large Hadron Collider in Europe. One result of their work is that the three have their names – Chunhui Chen, Jim Cochran and Soeren Prell – on the 2012 research paper describing how the collider’s ATLAS detector observed a new particle later confirmed to be the long-sought Higgs boson. The Higgs is the source of mass in subatomic particles. It’s one of the things that makes the universe as we know it possible.

Hints of Twisted Light Offer Clues to Dark Energy’s Nature
Cosmologists suggest that an exotic substance called quintessence could be accelerating the Universe’s expansion but the evidence is still tentative

Cosmologists say that they have uncovered hints of an intriguing twisting in the way that ancient light moves across the Universe, which could offer clues about the nature of dark energy the mysterious force that seems to be pushing the cosmos to expand ever-faster.
They suggest that the twisting of light, which they identified in data on the cosmic microwave background (CMB) collected by the Planck space telescope, and the acceleration of the Universe could be produced by a cosmic ‘quintessence’, an exotic substance that pervades the cosmos. Such a discovery would require a major revision of current theories

2-) conductivities ”the hexagonal perovskite-related oxides” and shed light on the underlying mechanisms responsible for their conductivity. Their findings lead the way to uncovering other similar materials, furthering research on developing low-cost and scalable renewable energy technologies.
Over the past few years, fuel cells have become a focal point of research in eco-friendly technology because of their superior abilities to store and produce renewable energy and clean fuel. A typical type of fuel cell gaining ground is the oxide-ion-conducting fuel cell, which is primarily made of materials through which oxide ions (oxygen ions:
