Counting semi-viable bacteria in cheese
The Wageningen researcher Christine Bunthof has developed a direct method for counting bacteria in dairy products. The method not only distinguishes viable and non-viable bacteria but also semi-viable bacteria. These are too weak to divide, but still exhibit activity. The semi-viable bacteria play an important role in cheese ripening and therefore... view more... (2002-05-23)
Scientists learn how the brain 'boots up' to process information from the senses

The ink is mightier than the pen - against forgery
Inks which cannot be photocopied - to confound bank-note forgers - are exciting printers of most of the world`s major currencies. A team from colour chemistry, led by Professor David Lewis and Dr Long Lin, has created an ink which changes colour when copied or scanned, to prevent forgers colour matching banknotes. "There are already hundreds of... view more... (2002-06-07)
Launch of weather satellite CD-ROM
The CD-ROM has been produced on behalf of the Coordination Group for Meteorological Satellites Meteorological Satellites (CGMS). Its production follows nearly 40 years of data from space, helping improve meteorology, monitoring of the climate, the state of the oceans, land surfaces and planetary atmosphere. view more (1999-08-17)
Paint-on laser could rescue computer chip industry
Researchers at the University of Toronto have created a laser that could help save the $200-billion dollar computer chip industry from a looming crisis dubbed the "interconnect bottleneck." view more (2006-04-18)
Gold beads show previously unseen parts of the eye
A new study recently published in Journal of Vision, an online, free access publication of the Association for Research in Vision and Ophthalmology (ARVO), shows that gold beads injected into eye tissue can be used to obtain images of important structures in the orbit that cannot be seen with Magnetic Resonance Imaging (MRI) or other imaging... view more...

Hearing changes how we perceive gender
Think about the confused feelings that occur when you meet someone whose tone of voice doesn't seem to quite fit with his or her gender. view more (2007-10-25)
Action video games improve vision
Video games that involve high levels of action, such as first-person-shooter games, increase a player's real-world vision, according to research in today's Nature Neuroscience. view more (2009-03-30)
Does playing violent video games increase aggression in teenagers?
Playing violent video games seems to increase hostility and anger in teenagers, but it may not be just related to whether the game contains violence. A study carried out by Anna Warm, whilst at the Department of Psychology, University of Central Lancashire, presented today Thursday 7 September at The British Psychological Society's Social... view more...

Adults with lazy eye can improve
Young adults with amblyopia, or lazy eye, can improve substantially and retain their gains under a new treatment developed by researchers at USC and three Chinese universities. view more (2005-12-21)
Behavioral studies show UV contributes to marsupial color vision
Work reported this week provides new evidence that marsupials, like primates, have functional color vision based on three different types of color photoreceptor cones-but unlike primates, a component of marsupial color vision includes sensitivity to ultraviolet wavelengths. view more (2006-03-21)
Lemurs' fur color may not define species
Different coat colour might not correspond to different species for nocturnal lemurs. In a study published today in the open access journal BMC Evolutionary Biology, researchers find that lemurs that appeared to belong to different species because they have strikingly different coat colours, are in fact genetically related and belong to the same... view more...

Optical illusions, mirages that don't deceive
The aim of this paper is to dispel the excessively widespread myth that optical illusions are errors of the visual system. In 1978, Stanley Coren and Joan Stern Girgus published one of the most significant works of scientific literature in the last few decades, entitled "Seeing is Deceiving: The Psychology of Visual Illusions". view more (2006-07-24)

Eye tissue shortage endangers clinical research's future
The future of clinical ophthalmology may be endangered by the decline in the number of human donor eyes provided by U.S. eye banks. view more (2006-07-12)
Research Shows How Visual Stimulation Turns Up Genes to Shape the Brain
Scientists have long known that brains need neural activity to mature and that sensory input is most important during a specific window of time called the "critical period" when the brain is primed for aggressive learning. view more (2006-05-08)
New nationwide study will evaluate effect of antioxidants and fish oil on progression of AMD
The National Institutes of Health (NIH) announces a nationwide study to see if a modified combination of vitamins, minerals, and fish oil can further slow the progression of vision loss from AMD, the leading cause of vision loss in the United States for people over age 60. view more (2006-10-12)
