Vision may be less important to “seeing” than is the brain’s ability to process points of light into complex images, according to a new study of the fruit fly visual system currently published in the online journal Nature Communications.
University of Virginia researchers have found that the very simple eyes of fruit fly larvae, with only 24 total photoreceptors (the human eye contains more than 125 million), provide just enough light or visual input to allow the animal&rsqu........ Read more »

Our universe may exist inside a black hole. This may sound strange, but it could actually be the best explanation of how the universe began, and what we observe today. It’s a theory that has been explored over the past few decades by a small group of physicists including myself.
Successful as it is, there are notable unsolved questions with the standard big bang theory, which suggests that the universe began as a seemingly impossible “singularity,” an infinitely small point co........ Read more »

“Our findings provide a deeper understanding of how memories are created,” explained the research team leader Thomas Carew, a professor in NYU’s Center for Neural Science and dean of NYU’s Faculty of Arts and Science. “Memory formation is not simply a matter of turning molecules on and off; rather, it results from a complex temporal and spatial relationship of molecular interaction and movement.”...

Scientists have cracked a molecular code that may open the way to destroying or correcting defective gene products, such as those that cause genetic disorders in humans.
The code determines the recognition of RNA molecules by a superfamily of RNA-binding proteins called pentatricopeptide repeat (PPR) proteins.
When a gene is switched on, it is copied into RNA. This RNA is then used to make proteins that are required by the organism for all of its vital functions. If a gene is defective, it........ Read more »

To participate successfully in life, it is important to be able to read and write. Nevertheless, many children and adults have difficulties in acquiring these skills and the reason is not always obvious. They suffer from dyslexia which can have a variety of symptoms. Thanks to research carried out by Begoña Díaz and her colleagues at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig, a major step forward has been made in understanding the cause of dyslexia.........

NOTHING seems more real than the world of everyday objects, but things are not as they seem. A set of relatively simple experiments reveals enormous holes is our intuitive understanding of physical reality. Trying to explain what goes on leads to some very peculiar and often highly surprising theories of the world around us.... Read more »

Humans have changed the face of the Earth by significantly altering the natural movements of chemicals on the planet’s surface, according to a new study by geochemists at Woods Hole Oceanographic Institution (WHOI).
The scientists analyzed how 77 different elements were transferred between rock, soil, and water via natural processes (such as volcanic eruptions, plant growth, and erosion) versus human activities (such as mining, agriculture, and construction). They concluded that the mov........ Read more »

A major breakthrough by scientists at Queen’s could lead to more effective treatments for throat and cervical cancer.
The discovery could see the development of new therapies, which would target the non-cancerous cells surrounding a tumour, as well as treating the tumour itself.
Researchers at Queen’s Centre for Cancer Research and Cell Biology have found that the non-cancerous tissue, or ‘stroma’, surrounding cancers of the throat and cervix, plays an important rol........ Read more »

Diseased trees in forests may be a significant source of methane that causes climate change, according to a study by researchers at the Yale School of Forestry & Environmental Studies (F&ES) published in Geophysical Research Letters.
Sixty trees sampled at Yale Myers Forest in northeastern Connecticut contained concentrations of methane that were as high as 80,000 times ambient levels. Normal air concentrations are less than 2 parts per million, but the Yale researchers found average levels o........ Read more »

ANN ARBOR, Mich. — How do stem cells preserve their ability to become any type of cell in the body? And how do they “decide” to give up that magical state and start specializing?
If researchers could answer these questions, our ability to harness stem cells to treat disease could explode. Now, a University of Michigan Medical School team has published a key discovery that could help that goal become reality.
