This area deals with the fundamental laws and building blocks of nature and how they interact, the properties and the behavior of matter, and research into space and time and their structures.
innovations-report provides in-depth reports and articles on subjects such as astrophysics, laser technologies, nuclear, quantum, particle and solid-state physics, nanotechnologies, planetary research and findings (Mars, Venus) and developments related to the Hubble Telescope.
Scientists at the University of Sheffield and Lockheed Martin Solar and Astrophysics Lab have solved a 127-year-old problem about the origin of supersonic plasma jets (spicules) which continuously shoot up from the Sun. Their findings are published in today’s edition of Nature.
Spicules, are jets of gas or plasma that are propelled upwards from the surface of the Sun at speeds of about 90,000 kilometres per hour. They are fairly short lived, with each jet lasting only about 5 minutes, but r
Two of the biggest physics breakthroughs during the last decade are the discovery that wispy subatomic particles called neutrinos actually have a small amount of mass and the detection that the expansion of the universe is actually picking up speed.
Now three University of Washington physicists are suggesting the two discoveries are integrally linked through one of the strangest features of the universe, dark energy, a linkage they say could be caused by a previously unrecognized subatomic
New research may lead to better catalysts for hydrogen fuel cells
Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory and the New Jersey Institute of Technology have taken steps toward understanding how a titanium compound reacts with a hydrogen-storage material to catalyze the release and re-absorption of hydrogen. Their results, appearing in the July 19, 2004, issue of Applied Physics Letters, may help scientists learn how similar catalysts work, improve
A rare event in the history of space exploration took place yesterday (25 July) when the second European-Chinese Double Star spacecraft lifted off a day early from Taiyuan spaceport, west of Beijing, on a Long March 2C rocket.
The launch of the spacecraft, officially called Tan Ce 2 (Explorer 2), was brought forward one day to avoid bad weather. Lift off occurred at 08:05:18 BST (07:05:18 GMT or 15.05:18 local time).
Preliminary analysis of spacecraft data indicate that th
A new study has caught a newborn star similar to the sun in a fiery outburst. X-ray observations of the flare-up, which are the first of their kind, are providing important new information about the early evolution of the sun and the process of planet formation.
The study, which was conducted by a team of astronomers headed by Joel Kastner of the Rochester Institute of Technology that included David Weintraub from Vanderbilt, is reported in the July 22 issue of the journal Nature.

Scientists using measurements from NASA’s Solar Radiation and Climate Experiment (SORCE) satellite have discovered that Venus and sunspots have something in common: they both block some of the sun’s energy going to Earth.
Using data from NASA’s SORCE satellite, scientists noticed that, when Venus came between the Earth and the sun on June 8, the other planet reduced the amount of sunlight reaching Earth by 0.1 percent. This Venus transit occurs when, from an earthly perspective, Ven
