Yesterday in a press conference and speech in North Dakota, Republican presidential candidate Donald Trump announced what some are terming his energy policy. His announcement was extremely short on specifics, included factual inaccuracies, and in some cases contained obvious internal contradictions. As such, what he said might better be termed "energy aspirations." We'll have...
Electric-field-induced charge separation (polarization) is the most fundamental manifestation of the interaction of light with matter and a phenomenon of great technological relevance. Nonlinear optical polarization produces coherent radiation in spectral ranges inaccessible by lasers and constitutes the key to ultimate-speed signal manipulation. Terahertz techniques have provided experimental access to this important observable up to frequencies of several terahertz. Here we demonstrate that attosecond...

Here’s some drone news worth buzzing about. Researchers have developed insect-sized flying robots that have the ability to perch on objects using static electricity in order to conserve...
REDMOND, Wash. – Microsoft is kicking up its targets for environmentally sustainable cloud computing by pledging that half of the electricity to power its data centers will come...
The deep ocean is the largest and least-explored ecosystem on Earth, and a uniquely energy-poor environment. The distribution, drivers and origins of deep-sea biodiversity remain unknown at global scales. Here we analyse a database of more than 165,000 distribution records of Ophiuroidea (brittle stars), a dominant component of sea-floor fauna, and find patterns of biodiversity unlike known terrestrial or coastal marine realms. Both patterns...
Circadian clocks are fundamental to the biology of most eukaryotes, coordinating behaviour and physiology to resonate with the environmental cycle of day and night through complex networks of clock-controlled genes. A fundamental knowledge gap exists, however, between circadian gene expression cycles and the biochemical mechanisms that ultimately facilitate circadian regulation of cell biology. Here we report circadian rhythms in the intracellular concentration of magnesium...
Throw some capacitors into sites like this, and you could potentially harvest electricity with the tide. (credit: Flickr user Alf Igel)
Every year, the Dutch physics community gets together to celebrate the year in physics. These are some highlights from the meeting. Since it is a meeting, it is not possible...
Magnesium is not usually considered to be a constituent of Earth's core, but its presence there has now been proposed to explain an ongoing enigma — the identity of the energy sources that drive our planet's magnetic field. See Letter p.387
