(Phys.org) -- Researchers at the SLAC National Accelerator Laboratory have captured the most detailed images to date of airborne soot particles, a key contributor to global warming and a health hazard.

Researchers from North Carolina State University have developed a new technique for controlling the crystalline structure of titanium dioxide at room temperature.

(Phys.org) -- Melanin – the pigment that colours skin, eyes and hair – could soon be the face of a new generation of biologically friendly electronic devices used in applications such as medical sensors and tissue stimulation treatments.

(Phys.org) -- The positive and sometimes unexpected impact of particle physics is well documented, from physicists inventing the World Wide Web to engineering the technology underlying life-saving magnetic resonance imaging (MRI) devices. But sometimes the raw power of huge experiments and scientific ambition draw the recognition of those seeking only the most extreme achievements on Earth.

(Phys.org) -- The world’s smallest three-dimensional optical cavities with the potential to generate the world’s most intense nanolaser beams have been created by a scientific team led by researchers with the DOE’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley.

Modern research tools like supercomputers, particle colliders, and telescopes are generating so much data, so quickly, many scientists fear that soon they will not be able to keep up with the deluge.

(Phys.org) -- The famous physicist Niels Bohr first conceived of the notion of quantum jumps, or quantum leaps, in 1913. Bohr understood quantum jumps as objective events in which an atom emits or absorbs a photon, causing an electron to jump from one energy level – or quantum state – to another inside the atom.

(Phys.org) -- “If you made a long distance phone call or sent an email today, or if you’re wearing clothes, then you are benefiting directly from our laser services,” says Marla Dowell, leader of PML’s Sources and Detectors Group, the nation’s keeper of a family of standards that now permit laser calibrations at power levels from nanowatts to hundreds of kilowatts and energy levels from femtojoules to megajoules.

A University of Alberta team has made an important breakthrough in the race to find a viable replacement for supply of technetium-99m, an important isotope produced by Canada's Chalk River reactor.

(Phys.org) -- Matter exhibits weird properties at very cold temperatures.

Smooth wrinkles and sharply crumpled regions are familiar motifs in biological and synthetic sheets, such as plant leaves and crushed foils, say physicists Benny Davidovitch, Narayanan Menon and colleagues at the University of Massachusetts Amherst, but how a featureless sheet develops a complex shape has long remained elusive.

Imagine a world without man-made climate change, energy crunches or reliance on foreign oil.

The quantum computer is a futuristic machine that could operate at speeds even more mind-boggling than the world's fastest super-computers.

For the first time, researchers have produced a coherent, laser-like, directed beam of light that simultaneously streams ultraviolet light, X-rays, and all wavelengths in between.

(Phys.org) -- When two photons simultaneously enter two input ports of a beam splitter, their paths interfere destructively, which causes the photons to simultaneously exit the beam splitter through the same output port. Because this quantum interference effect changes the input into a different output, it could have applications in quantum information processing. But whereas the two photons are usually identical in experiments demonstrating this effect, a new study has demonstrated that quantum interference can also occur between two photons with different frequencies, giving researchers an additional degree of control.
