• Non-invasive first trimester blood test reliably detects Down's syndrome

  New research has found that routine screening using a non-invasive test that analyzes fetal DNA in a pregnant woman's blood can accurately detect Down's syndrome and other genetic fetal abnormalities in the first trimester. Published online in Ultrasound in Obstetrics & Gynecology, the results sugge more

• Vitamin C does not lower uric acid levels in gout patients

  Despite previous studies touting its benefit in moderating gout risk, new research reveals that vitamin C, also known ascorbic acid, does not reduce uric acid (urate) levels to a clinically significant degree in patients with established gout. Vitamin C supplementation, alone or in combination with more

• Sexually explicit material affects behavior in young people less than thought

  Viewing sexually explicit material through media such as the Internet, videos, and magazines may be directly linked with the sexual behavior of adolescents and young adults, but only to a very small extent. That is the conclusion of a new study published in The Journal of Sexual Medicine. The findin more

• Tunable narrow band filter for CARS microscopy

  In this letter we present an approach to CARS microscopy, which compromises between fast acquisition rates and the amount of chemical information obtained. By using a light modulator as tunable filter in concert with narrowband pump and broadband Stokes pulses, we demonstrate an experimental arrange more

• Tilted short base Fabry‐Perot interferometer with inverted resonances in feedback system of widely tunable linear laser

  The method of spectral selection based on weak coupling between a tilted short Fabry-Perot interferometer and a semiconductor optical amplifier has been proposed. An unusual effect was discovered at a certain inclination. Narrowband spectral maxima are observed in the light backreflected from a tilt more

• High energy THz generation from meter‐long two‐color filaments in air

  High energy THz emissions from meter-long, twocolor femtosecond laser-induced filament in air are demonstrated at a distance of over 10 m from the laser. The THz emission is linearly proportional to the N2 fluorescence inside the filaments under the same excitation condition; this provides a sensiti more
