Observations of distant galaxies show fundamental constant unchanged in 7 billion years

A fundamental number that affects the color of light emitted by atoms as well as all chemical interactions has not changed in more than 7 billion years, according to observations by a team of astronomers charting the evolution of galaxies and the universe.

The results are being reported today (Monday, April 18) at the annual meeting of the American Physical Society (APS) by astronomer Jeffrey Newman, a Hubble Fellow at Lawrence Berkeley National Laboratory representing DEEP2, a

Tom Cowan’s team cultivating new laser technology for more precise cancer treatments

Tom Cowan’s team is thinking smaller, but with big impact. Particle accelerators are a key research tool in a high energy physicist’s arsenal, but they take up a lot of space – miles and miles of it. But at the University of Nevada, Reno, smaller is better.

Cowan, director of the Nevada Terawatt Facility at the University, and his research partners have produced a proton

SMART-1 search for lunar peaks of eternal light

ESA’s SMART-1 mission to the Moon has been monitoring the illumination of lunar poles since the beginning of 2005, about two months before arriving at its final science orbit.

Ever since, the AMIE on-board camera has been taking images which are even able to show polar areas in low illumination conditions. Images like these will help identify if peaks of eternal light exist at the poles.

SMART-1 took views of the North Polar Region from a distance of 5000 km during a paus

New isotope gives a glimpse of the origins of precious metals

The beginnings of precious metals like gold can be traced to the blink of an eye in an exploding star billions of years ago, and scientists at the National Superconducting Cyclotron Laboratory (NSCL) at Michigan State University have been able to scrutinize a crucial step in that process.

By reproducing the processes inside supernovas in a laboratory, scientists have resurrected an isotope of nickel – one that no longer exists in nature, but is an important link in the birth of t

Duke theorists play role in search for superhot ’quark-gluon plasma’

Duke University theoreticians said their predictions helped guide the efforts of experimenters using Brookhaven National Laboratory’s Relativistic Heavy Ion Collider (RHIC) atom smasher to create an almost perfectly flowing fluid of hot, dense matter.

Duke physics professor Berndt Mueller and assistant physics professor Steffen A. Bass said that some of the experimental evidence would also support the idea that these collisions have recreated a state of matter — a quark-glu

Physicists demonstrate quantum mechanical nature of heat flow

One of the hallmarks of quantum mechanics — the laws of physics that apply on very small scales — is the wave nature exhibited by sub-atomic particles such as electrons. An electron presented with two paths to a destination will use its wave nature to traverse both paths and, depending on the parameters of the two paths, will constructively or destructively interfere with itself at its destination, leading to a high or low probability of it appearing there.

A classic demonstration of th
