Inventor and AC electricity proponent Nikola Tesla was on a mission to transmit energy through thin air almost a century ago, but, claims about a conspiracy to keep his work quiet aside, experimental attempts at the feat have resulted in cumbersome devices that only work over very small distances.

The Toyota Research Institute of North America and Duke University have demonstrated the feasibility of wireless power transfer using metamaterials to create a "superlens" that focuses low-frequency magnetic fields over distances much larger than the size of the transmitter and receiver. The superlens translates the magnetic field emanating from one power coil onto its twin nearly a foot away, inducing an electric current in the receiving coil.

A double-blind trial has determined that tea and coffee aren't just morning pick-me-ups, they are also a memory enhancer.

That goes for carbonated drinks containing caffeine also.

Paranthropus boisei, nicknamed "Nutcracker Man" because of his big flat molar teeth and powerful jaws,lived in East Africa between 2.4 million-1.4 million years ago.

A new paper postulates that he survived mainly on a diet of tiger nuts - edible grass bulbs still eaten in parts of the world today- along with fruits and invertebrates, like worms and grasshoppers.  

This idea dates back to the Russians in the early 1970s. The surface of Venus is far too hot, and the atmosphere too dense, for Earth life. However, our air is a lifting gas on Venus with about half the lifting power of helium on Earth. A habitat filled with normal air will float high in the dense Venus atmosphere, The atmospheric pressure there is the same as Earth sea level (1 bar). Temperatures are perfect for Earth life too, just over 0°C.

Bearing in mind that the word ‘ovoid’ means ‘egg-shaped’, the question : ‘Why are eggs ovoid?’ has much in common with questions like or ‘Why are hearts heart-shaped?’ or ‘Why are sausages sausage-shaped?’ And the Zen-like qualities of the egg-shape question have not escaped professor Yutaka Nishiyama, (Osaka University of Economics, Japan) who decided to approach this enigmatic problem from a mathematical viewpoint in his paper ‘The mathematics of egg shape’ (Osaka Keidai Ronshu, Vol. 58, Sept. 2007). In which the professor not only developed a formula to describe egg-shapes -

In the comments section of my previous article I demonstrated an optical Theremin. This article is the build for that circuit. The circuit and circuits that are similar to it in function have also been called a “Light Sensitive Tone Generator,” “Photo Theremin,” and “Audible Light Meter.” These three circuits are usually based on the two-transistor Light Sensitive Tone Generator from The Forrest Mims Circuit Scrapbook, Volume 1 (Radio Shack, 1976). The circuit built in this article is based instead on the 555 timer IC.

Marine cyanobacteria are tiny ocean plants that produce oxygen and make organic carbon using sunlight and CO2, and so they are primary engines of Earth's biogeochemical and nutrient cycles.

They nourish other organisms through the provision of oxygen and with their own body mass, which forms the base of the ocean food chain. Researchers have discovered a new benefit of these tiny cells: Cyanobacteria continually produce and release vesicles, spherical packages containing carbon and other nutrients that can serve as food parcels for marine organisms. The vesicles also contain DNA, likely providing a means of gene transfer within and among communities of similar bacteria, and they may even act as decoys for deflecting viruses.

The Z machine at Sandia National Laboratories is moving us toward a fusion future by stepping into the past - in this case using a 19th century device called a Helmholz coil, which is a pair of circular coils on a common axis with equal currents flowing in the same sense and that produces a nearly uniform magnetic field when electrified. 

In recent experiments, two Helmholz coils, installed to provide a secondary magnetic field to Z's huge one, unexpectedly altered and slowed the growth of magneto-Rayleigh-Taylor instabilities, an unavoidable, game-ending plasma distortion that usually spins quickly out of control and has sunk past efforts to achieve controlled fusion.
