Found -- the apple gene for red
...pple colour is dependant on light apples grown in darkness or even heavy shade don't turn red when they ripen," Dr Walker says. "That made it very likely that the gene we were looking for requires light to be activated." "By identifying master genes that were activated by light, Adam was able to pinpoint th...New poinsettia for the nontraditionalist
... in September, the plants need to be kept in total darkness from 5:00 p.m. to 8:00 a.m. "The plants are so sensitive to light that if people open the closet door for one peek during that time period, or even shine a flashlight in, the plants won't change color," said Warnock....Satellite data vital to UN climate findings
...Earth's Polar Regions because of their remoteness, darkness and cloudiness. An instrument known as the Advanced Synthetic Aperture Radar (ASAR) allows Envisat to produce high-quality images of ice sheets in Greenland and Antarctica because it is able to pierce through clouds and darkness. Using satellite d...'Good vibrations' from deep-sea smokers may keep fish out of hot water
...tions of black smokers be the reason fish in total darkness avoid being poached by waters as hot as 750 F? And might similar sounds guide them to the smorgasbord of tube worms, mussels, shrimp, snails and other fauna at vents with more temperate waters? Want to be the first on your block to hear what a black ...Research suggests a significant circadian rhythm in swim performance lasting 2-4 minutes
.../wake schedule, specifically one hour of sleep in darkness and two hours of wakefulness in dim light, repeated throughout the length of observation. This study design distributed multiple masking factors equally across the 24-hour day and allowed multiple performance assessments to be conducted over a short...ACS News Service Weekly PressPac -- March 21, 2007

Researchers have been developing electrochromic polymers for decades, but Xus lab is one of just a few using the technology to develop improved eyewear. Xu developed a prototype of the eyewear that ......master-slave relationship. "The morning cells like darkness and they become the master clocks in winter, and the evening cells process light information, so they become the masters in the summer, though it all may happen gradually. We don't know how the switch from slave to master actually happens, but at som...Satellites shed light on global warming
...sen-A and Larsen-B ice shelves. The remoteness, darkness and cloudiness of Earths Polar Regions make them difficult to study. An instrument known as the Advanced Synthetic Aperture Radar (ASAR) allows Envisat to produce high-quality images of ice sheets because it is able to pierce through clouds and darkn...Light sticks may lure turtles to fishing lines
...ttracted to glowing light sticks, whether in total darkness or underneath a night sky, Wang said. When the lights werent activated, they were unappealing. The experiments were conducted at the National Marine Fisheries Services Galveston Laboratory in Texas and at a turtle nesting area in south Florida. The...Research finds that circadian rhythms dominate all life functions
...nd gene expression can be impacted by daylight and darkness -- or a lack of both. For example, while gene expression oscillates in mice exposed to a constant state of dim light or darkness, the groups of genes that typically oscillate together -- such as genes responsible for the function of an organ or a spe...MU researchers make discovery in molecular mechanics of phototropism
...m said. NPH3 exists as a phosphorylated protein in darkness and is rapidly dephosphorylated by a yet unidentified protein phosphatase in response to phot1 photoactivation by blue light. Liscum and Pedmale now plan to study which amino acids on NPH3 are reversibly phosporylated and how NPH3 is involved in r...
