Sharktooth Hill near Bakersfield, Calif., is the home of the most extensive marine bone bed in the world, a 100-square-mile layer of shark, seal, ray, whale, turtle and fish bones. Researchers have analyzed the 15-million-year-old fossils to decipher the history of what used to be the California coastline, reconstructing a 700,000-year period of warming climate [...]

Researchers have identified a new appetite suppressant for promoting weight loss that they say works in rodents and may one day be used to develop an effective anti-obesity treatment.
A team of physicists and engineers has demonstrated exquisite control of single particles of light — photons — on a silicon chip to make a major advance towards long-sought-after quantum technologies, including super-powerful quantum computers and ultra-precise measurements.

Embryologists have clarified the role that retinoic acid plays in limb development. A new study showed that retinoic acid controls the development (or budding) of forelimbs, but not hindlimbs, and that retinoic acid is not responsible for patterning (or differentiation of the parts) of limbs. This research corrects longstanding misconceptions about limb development and provides [...]

Adolescent obesity is associated with having less sleep. Reduction in sleep could be related to a higher caffeine intake, more hours of technology use and increased symptoms of sleep disorders (such as snoring).
The results of this study suggest a potentially favorable effect of bright light therapy on primary sexual dysfunctions. A larger study is now needed to confirm these preliminary findings and to test whether bright light therapy may be of help for the treatment of sexual dysfunctions that are associated with certain psychiatric illnesses, such as [...]

Researchers have developed a new method for using computer graphics to simulate and render an accurate visualization of a lunar eclipse. The model uses celestial geometry of the sun, Earth, and moon, along with data for the Earth’s atmosphere and the moon’s peculiar optical properties to create picture-perfect images of lunar eclipses.
