The vision system used to process color is separate from that used to detect motion, according to a new study by researchers at New York University’s Center for Developmental Genetics and in the Department of Genetics and Neurobiology at Germany’s University of Würzburg.

The findings run counter to previous scholarship that suggested motion detection and color contrast may work in tandem.

Whether motion vision uses color contrast is a controversial issue that has been investigated in several species--from insects to humans. In human vision, it had been widely believed that color and motion were processed by parallel pathways. More recently, however, the complete segregation of motion detection and color vision came into question.

Community groups across England are all set to spring clean their neighbourhoods with the launch of a GBP50 million lottery-funded grants programme today, Wednesday 19 March.

The Community Spaces programme will provide grants and support to community groups wanting to make their neighbourhoods cleaner and greener. Community Spaces will help local people improve and create play areas, community gardens, parks, wildlife areas, ponds, courts and village greens.

Researchers at the National Institute of Standards and Technology (NIST) have set the stage for building the “evolutionary link” between the microelectronics of today built from semiconductor compounds and future generations of devices made largely from complex organic molecules. In an upcoming paper in the Journal of the American Chemical Society, a NIST team demonstrates that a single layer of organic molecules can be assembled on the same sort of substrate used in conventional microchips.

The ability to use a silicon crystal substrate that is compatible with the industry-standard CMOS (complementary metal oxide semiconductor) manufacturing technology paves the way for hybrid CMOS-molecular device circuitry—the necessary precursor to a “beyond CMOS” totally molecular technology—to be fabricated in the near future.

Researchers at NIST and the Joint Quantum Institute (NIST/University of Maryland) have developed a new method for creating pairs of entangled photons, particles of light whose properties are interlinked in a very unusual way dictated by the rules of quantum physics. The researchers used the photons to test one of the fundamental concepts in quantum theory.

In the experiment, the researchers sent a pulse of light into both ends of a twisted loop of optical fiber. Pairs of photons of the same color traveling in either direction will, every so often, interact in a process known as “four-wave mixing,” converting into two new, entangled photons, one that is redder and the other that is bluer than the originals.

If you had one hundred unlabeled DNA samples, taken from people all around the world, could you use that DNA to determine where the original donors came from?

With major improvements in genotyping technology, geneticists are now getting better and better at this game, and a recent paper in Science reports the largest study to date of human genetic diversity: 650,000 genetic differences scrutinized in nearly 1000 different individuals from 51 different populations.

Studies like this one lay important groundwork to help us understand how human genomes differ around the world, how differences in our genes and environments together make us healthy or sick, and how very ancient migrations led to the structure of today's human populations around the globe.

Twice in two days Botulinum toxin (Botox) has graced our front page, and it's not just because it makes Joan Rivers look like The Joker.

Yesterday we reported that Botox has helped infants with CHARGE Syndrome and today we discovered an article in Medical Hypotheses talking about its many beneficial effects.

Not bad press for an often fatal poison produced by a rare type of food poisoning bacteria.
