The Canon CF-1 Digital Retinal Camera, introduced earlier this year, features a redesigned optical system that achieves high-resolution diagnostic images and outstanding operability. When attached to a Canon EOS 40D Digital SLR Camera (sold separately), which provides up to 10.1 million pixels, the CF-1 is capable of delivering clear and detailed diagnostic images for virtually immediate review. The Canon CF-1 Digital Retinal Camera offers exceptional ease of use and an ergonomic, streamlined design helps to achieve improved operation by motorizing procedures usually performed by hand. All CF-1 functions are integrated into a single tabletop unit with a power supply built directly into the base. The new compact design allows for closer interaction with the patient and easier access to the patient’s eyes.

The Yellowstone “supervolcano” rose at a record rate since mid-2004, likely because a Los Angeles-sized, pancake-shaped blob of molten rock was injected 6 miles beneath the slumbering giant, University of Utah scientists report in the journal Science.
“There is no evidence of an imminent volcanic eruption or hydrothermal explosion. That’s the bottom line,” says seismologist Robert B. Smith, lead author of the study and professor of geophysics at the University of Utah. “A lot of calderas [giant volcanic craters] worldwide go up and down over decades without erupting.”

Dutch biologist Marc van Roosmalen has discovered a new species of peccary, a member of the pig family, in the basin of the Rio Aripuanã in the south-eastern Amazon region. The divergence time from the already known peccary species (the time which has passed since the evolutionary division) has been set at one to 1.2 million years.
This species has been christened giant peccary (Pecari maximus) by the researchers on account of its size. The holotype of the species can be found in the museum of the Instituto Nacional de Pesquisas da Amazônia (INPA) in Manaus. The giant peccary was known by the local Tupi Indians as Caitetú Mundè, which means ‘great peccary which lives in pairs’.

There are unknown creatures lurking under the windswept islands of the Aleutians, according to a team of scientific divers from the University of Alaska Fairbanks.
This summer, while completing the second phase of a two-year broad scientific survey of the waters around the Aleutian Islands, scientists have discovered what may be three new marine organisms. This year’s dives surveyed the western region of the Aleutians, from Attu to Amlia Island, while last year’s assessment covered the eastern region.

Scientists in Taiwan are reporting new insights into why diets rich in fruits and vegetables reduce the risk of obesity. Their study focuses on healthful natural antioxidant compounds called flavonoids and phenolic acids.
In the study, Gow-Chin Yen and Chin-Lin Hsu point out that large amounts of those compounds occur in fruits, vegetables, nuts and plant-based beverages such as coffee, tea, and wine. Scientists long have known that flavonoids and phenolic acids have beneficial health effects in reducing the risk of heart attacks, cancer, obesity, and other disorders. However, there has been uncertainty about exactly how these compounds affect adipocytes, or fat cells.

Researchers in the University of Iowa Roy J. and Lucille A. Carver College of Medicine have discovered the first two genes involved in moisture sensing (hygrosensation). The discovery also reveals a “two-sensor” hygrosensing system in fruit flies that may allow the flies to detect subtle changes in humidity — an ability that is critical for the flies’ survival.

The known association between breast feeding and slightly higher IQ in children has been shown to relate to a particular gene in the babies, according to a report in the Proceedings of the National Academy of Sciences.
In two studies of breast-fed infants involving more than 3,000 children in Britain and New Zealand, breastfeeding was found to raise intelligence an average of nearly 7 IQ points if the children had a particular version of a gene called FADS2.

According to the Trimbos Institute, anyone who sniffs cocaine once has a 15 to 20% likelihood of becoming addicted to this hard drug. Why does the recreational user only try it once whereas another person becomes physically and mentally dependent on the drug? Behavioural Pharmacologist Inge de Jong, attached to the LUMC (Leiden University Medical Center) and the Faculty of Mathematics and Natural Sciences, sought an explanation in the effect of stress hormones.

College students who drink alcohol mixed with so-called “energy” drinks are at dramatically higher risk for injury and other alcohol-related consequences, compared to students who drink alcohol without energy drinks, according to new research from Wake Forest University School of Medicine.

University of Manchester researchers have identified a genetic variant in a region on chromosome 6 that is associated with rheumatoid arthritis (RA), the most common inflammatory arthritis affecting 387,000 people in the UK.
