Enhancing activity of marijuana-like chemicals in brain helps treat

...abeled with a fluorescent protein that glows vivid green under a microscope. Having an unequivocal way to identify the cells allowed them to tease apart the functions of the different cell types. Malenka's lab has long studied how the communication between different neurons is modified by experience ...

NASA predicts nongreen plants on other planets

...lants on Earth absorbs blue and red light and less green light. Therefore, chlorophyll appears green. Although some green color is absorbed, it is less than the other colors. Previously, scientists thought plants are not e...

Progress toward artificial photosynthesis?

...d plants for inspiration. Photosynthesis in modern green plants involves an important intermediate step: the bonding of CO2 to nitrogen atoms to form carbamates. The German researchers thus also experimented with nitrogen-rich catalysts with structures that allow them to form carbamates. Their new class of...

Shedding new light on proteorhodopsin

...opsin has an absorption spectrum that peaks in the green wavelengths, so the cells swam when they were exposed to green light, but stopped when they were exposed to red light." In the absence of the azide respiratory ...

Turning green gunk to gold, anti-cancer gold

...her Zachary Q. Beck found the trick to turning the green gunk into gold---cancer fighting gold. "It was simply too difficult to use the native blue-green algae for high-level production using traditional fermentation approaches," said Sherman. But the compound, called cryptophycin 1, held so much promi...

Using brain scans, researchers find evidence for a two-stage model of human perceptual learning

...s into categories ?discerning, for example, that a green apple, and not a green tennis ball, belongs to "food." They describe it as a complex interplay between neurons that proces...

Large size crucial for Amazon forest reserves

..."What might look like a vast mantle of homogeneous green is actually a multicolored mosaic", said Lovejoy. And species that occur throughout the forest at the large scale actually may have very specific requirements at the fine scale. Large areas of forest encompass a wide enough variety of local condit...

Racing neurons control whether we stop or go

In the children’s game "red light green light," winners are able to stop, and take off running again, more quickly than their comrades. New research reveals that a similar race goes on in our brains, with impulse control being the big winner. "The research provides new insights into how t...

Scientists to track impact of Asian dust and pollution on clouds, weather, climate change

...serting into the cells a gene naturally present in green algae that "turns on" when exposed to light and enables the algae to swim toward the light. When the researchers shined light on the areas of the brain involved in smell, they could follow in real time what areas of the brain were reacting and whe...

Common algae helps illustrate mammalian brain electrical circuitry

Scientists unlock secret of what makes plants flower

...the protein through the plant by tagging it with a green fluorescent protein originally isolated from jellyfish, allowing it to be detected in living tissues using highly sensitive microscope systems. The team then grafted two plants together, only one of which contained the gene for the fluorescent ve...

MIT's ocean model precisely mimics microbes' life cycles

...e forests living in our oceans-tiny, single-celled green plants that dominate the ocean and produce half the oxygen we breathe on Earth. And it does so in a way that is consistent with the way real-world ecosystems evolve according to the principles of natural selection. Scientists use models such as t...
