Five tips to make casual encounters into new business opportunities. Plus, an upfront approach from Arel Moodie, co-owner of Extreme Entrepreneurship Education.

Physicists at JILA have created the first "frequency comb" in the extreme ultraviolet band of the spectrum, high-energy light less than 100 nanometers (nm) in wavelength. Laser-generated frequency combs are the most accurate method available for precisely measuring frequencies, or colors, of light. In reaching the new band of the spectrum, the JILA experiments demonstrated for the first time a very fine mini-comb-like structure within each subunit, or harmonic, of the larger comb, drastically sharpening the measurement tool.

The National Physical Laboratory Acoustics team has been investigating acoustic cavitation – the formation and implosion of micro cavities, or bubbles, in a liquid caused by the extreme pressure variations of high intensity sound waves – using the new NPL reference vessel and a chemical commonly found at crime scenes.

(PhysOrg.com) -- While physicist Robert Dicke is probably most famous for his work on the cosmic microwave background (CMB) – and being "scooped" while attempting to be the first to detect it – he also performed important work in optics.

It’s time to get scared. Nightmare On Elm Street, Psycho, Texas Chainsaw Massacre will be airing on TVs through to midnight tonight, Halloween.

(PhysOrg.com) -- Although materials scientists have theorized for years that a form of super-dense aluminum exists under the extreme pressures found inside a planet’s core, no one had ever actually seen it. Until now.

Researchers are able to achieve extremely high-resolution microscopy through a process known as stimulated emission depletion (STED) microscopy. This cutting-edge imaging system has pushed the performance of microscopes significantly past the classical limit, enabling them to image features that are even smaller than the wavelength of light used to study them. They are able to achieve this extreme vision by using a single-color fluorescent dye that absorbs and releases energy, revealing cells and cellular components (such as proteins) in unprecedented detail.

U.S. nuclear plants should be hardened to better withstand earthquakes and other extreme emergencies that could lead to a radioactive release, the Nuclear Regulatory Commission's Japan Task Force has recommended

Sheena Lindahl and Michael Simmons met their third day of college and started dating on their fourth. Both are business-oriented by nature; Lindahl juggled five jobs to pay for New York University and Simmons ran a Web development shop in high school. "My friend and I made $40,000 our senior year of high school, working 10 hours per week," says Simmons.

We, as emotional beings, place a high value on happiness and joy. Happiness is more than a feeling to us - it’s something we require and strive for. We’re so fixated on happiness that we define the pursuit of it as a right.
