Since the late 20th century, astronomers have been aware of data that suggest the universe is not only expanding, but expanding at an accelerating rate. According to the currently accepted model, this accelerated expansion is due to dark energy, a mysterious repulsive force that makes up about 73% of the energy density of the universe.

It seems impossible: Scientists from the Helmholtz-Zentrum Dresden-Rossendorf and the TU Dresden (Germany) were able to verify with an intermetallic compound of bismuth and nickel that certain materials actually exhibit the two contrary properties of superconductivity and ferromagnetism at the same time.

(PhysOrg.com) -- "When you pick up a spoon with your fingers, you are able to move it from side to side and rotate it too by moving thumb and forefinger in opposition," Iain Anderson tells PhysOrg.com. Your hand is a soft machine

Quantum mechanical methods can now be used to study gravity: At the Vienna University of Technology (TU Vienna), a measurement method was developed, which allows to test the fundamental theories of physics.

Israel's cabinet on Sunday announced it had approved the country's membership in the European Organisation for Nuclear Research, becoming the research group's first non-European delegation.

(PhysOrg.com) -- Physicist Nathan Whitehorn and his team at the IceCube station near the South Pole have failed to come up with evidence to prove that neutrinos come from, or are caused by, gamma ray bursts, (cosmic explosions) after a year of study.

If a new development from labs at MIT pans out as expected, someday the entire surface area of a building’s windows could be used to generate electricity — without interfering with the ability to see through them.

(PhysOrg.com) -- Researchers have achieved a breakthrough in quantum communications and computing using a teleporter and a paradoxical cat.

(PhysOrg.com) -- Dark matter, the mysterious substance that may account for nearly 25 percent of the universe, has so far evaded direct observation. But researchers from UCLA, Columbia University and other institutions participating in the international XENON collaboration say they are now closer than ever before.

The exploitation and utilization of new energy sources are considered to be among today's major challenges. Solar energy plays a central role, and its direct conversion into chemical energy, for example hydrogen generation by water splitting, is one of its interesting variants. Titanium oxide-based photocatalysis is the presently most efficient, yet little understood conversion process

Even if the finite nature of the resource stocks is not the only factor that influences oil prices, speculation also plays a role in this process: peak oil, that is the point in time when oil production cannot be increased despite maximum efforts, will be reached in the near to medium-term future – indeed, some analysts believe that it has already been reached.

An International team of scientists in the XENON collaboration, including several from the Weizmann Institute, announced on Thursday the results of their search for the elusive component of our universe known as dark matter. This search was conducted with greater sensitivity than ever before.

(PhysOrg.com) -- A dramatic and surprising magnetic effect of light discovered by University of Michigan researchers could lead to solar power without traditional semiconductor-based solar cells.

A step change in research relating to plasma nanoscience is needed for the world to overcome the challenge of sufficient energy creation and storage, says a leading scientist from CSIRO Materials Science and Engineering and the University of Sydney, Australia.

(PhysOrg.com) -- Harvard physicists have expanded the possibilities for quantum engineering of novel materials such as high-temperature superconductors by coaxing ultracold atoms trapped in an optical lattice -- a light crystal -- to self-organize into a magnet, using only the minute disturbances resulting from quantum mechanics. The research, published in the journal Nature, is the first demonstration of such a “quantum magnet” in an optical lattice.
