Repulsive gravity as an alternative to dark energy (Part 1: In voids)
Metal surface can repel electric charges
A clock that will last forever: Researchers propose a way to build the first space-time crystal
(Phys.org)—Imagine a clock that will keep perfect time forever, even after the heat-death of the universe. This is the "wow" factor behind a device known as a "space-time crystal," a four-dimensional crystal ...
Dark energy is real, say astronomers
(Phys.org)—Dark energy, a mysterious substance thought to be speeding up the expansion of the Universe is really there, according to a team of astronomers at the University of Portsmouth and LMU University ...
Researchers develop computer model of bacterial colony interactions
New Data Suggests We Don’t Live in a Void, and Supports Dark Energy
Engineers discover nanoscale balancing act that mirrors forces at work in living systems
(PhysOrg.com) -- A delicate balance of atomic forces can be exploited to make nanoparticle superclusters that are uniform in size---an attribute that's important for many nanotech applications but hard to ...
New project aims for fusion ignition
Russia and Italy have entered into an agreement to build a new fusion reactor outside Moscow that could become the first such reactor to achieve ignition, the point where a fusion reaction becomes self-sustaining ...
Quantum model helps solve mysteries of water
Water is one of the most common and extensively studied substances on earth. It is vital for all known forms of life but its unique behaviour has yet to be explained in terms of the properties of individual ...
A Theory of Dark Matter
Among the most astounding, unexpected, and important achievements of the past century (or even more) have been the discoveries of dark matter and dark energy, collectively dubbed the "dark sector."
Structurally reinforced hydrogel material developed using electrostatic repulsive force between nanosheets
A joint research group successfully developed a material that expresses a unique mechanical property by arranging oxide nanosheets, that electrostatically repel each other, in the direction perpendicular ...
Self-assembling structures open door to new class of materials
Researchers at the University of Illinois and Northwestern University have demonstrated bio-inspired structures that self-assemble from simple building blocks: spheres.
Large Hadron Collider could test hyperdrive propulsion
New tech application keeps bacteria from sticking to surfaces
Just as the invention of nonstick pans was a boon for chefs, a new type of nanoscale surface that bacteria can't stick to holds promise for applications in the food processing, medical and even shipping industries.
