Pulse oximetry can identify newborns with congenital heart disease

About 1 in every 120 babies are born with congenital heart disease (CHD), of which about 25 percent is critical, requiring special care early in life. CHD is responsible for more deaths in the first year of life than any other birth defect, but often outcomes can be improved with early detection.

Femtosecond-laser ablation of Xenopus melanocytes for studies of cell migration, wound repair

Using an ultrafast femtosecond laser, researchers at Tufts University in Medford, Mass., were able to label, draw patterns on, and remove individual melanocytes cells from a species of frog tadpole (Xenopus) without damaging surrounding cells and tissues.

Two-color stimulated emission depletion microscopy in living cells

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.

Flexible-fiber CO2 laser-assisted ablation safe for endoscopic assisted transsphenoidal craniotomies

A new study has shown the Flexible-Fiber CO2 laser to safely cut and coagulate during endoscopic assisted transsphenoidal craniotomies (TSC) without the line of sight problems encountered with conventional CO2 lasers.

RIKEN, JASRI produce first beam of X-ray laser light

RIKEN and the Japan Synchrotron Radiation Research Institute (JASRI) have successfully produced a first beam of X-ray laser light with a wavelength of 1.2 Angstroms. This light was created using SACLA, a cutting-edge X-ray Free Electron Laser facility unveiled by RIKEN in February 2011 in Harima, Japan.

Neuroscientists uncover the source of visual system's 'false alarms'

On rare occasion, the light-sensing photoreceptor cells in the eye misfire and signal to the brain as if they have captured photons, when in reality they haven't. For years this phenomenon remained a mystery. Reporting in the June 10 issue of Science, neuroscientists at the Johns Hopkins University School of Medicine have discovered that a light-capturing pigment molecule in photoreceptors can be triggered by heat, as well, giving rise to these false alarms.

Neuroscientists document deliberate control of touch sensations in human working memory

Neuroscientists of the Charité - Universitätsmedizin Berlin have now been able for the first time to document deliberate control of touch sensations in human working memory. It has been shown that the human brain can remember several touch sensations at the same time and consciously retrieve the touch if concentration is focused on these touches.
