Zooplankton, small fish and squid spend hardly any time at the surface when there's a full moon. To protect themselves from their natural enemies, they hide deeper down in the water on bright nights, coming up to the surface under cover of darkness when there's a new moon instead.
Since its introduction fifty or so years ago, thermography has been increasingly used by vets to pinpoint the cause of lameness in horses. The method is fast and safe and is based on a simple idea. The horse's body surface emits infrared radiation that can be detected by an infrared camera, which is both easy and inexpensive to use. The camera produces a coloured image that shows the variation in surface temperature across the area investigated.
PHILADELPHIA (March 27, 2013) -- In 370 million-year-old red sandstone deposits in a highway roadcut, scientists have discovered a new species of armored fish in north central Pennsylvania.
Bunk beds and baby change tables are among the hidden dangers around the home causing serious injury and death to Queensland children.
In the 2013 Consumer product-related injuries in Queensland children report, prepared by QUT's Centre for Accident Research and Road Safety - Queensland (CARRS-Q), more than 475,000 Queensland children sustained injuries requiring emergency department treatment between 2004 and 2011.
The genome of the mountain pine beetle – the insect that has devastated B.C.'s lodgepole pine forests – has been decoded by researchers at the University of British Columbia and Canada's Michael Smith Genome Sciences Centre.
This is a first for the mountain pine beetle and only the second beetle genome ever sequenced. The first was the red flour beetle, a pest of stored grains. The genome is described in a study published today in the journal Genome Biology.
Almost all foodstuffs contain the genetic material of those animal and plant species that were used in their preparation. Scientists at the Institute of Molecular Genetics, Genetic Security Research and Consulting at Johannes Gutenberg University Mainz (JGU) have developed a novel screening procedure that provides for highly sensitive, quantifiable analysis of animal, plant, and microbial substances present in foodstuffs.
Bonn, Germany 27 March 2013 – In diseases like Alzheimer's and Parkinson's endogenous proteins accumulate in the brain, eventually leading to the death of nerve cells. These deposits, which consist of abnormally formed proteins, are supposed to migrate between interconnected areas of the brain, thereby contributing to the development of the illness. Now, a new laboratory study by scientists from Germany and the US shows that certain protein particles are indeed capable of multiplying and spreading from one cell to the next.
(Santa Barbara, Calif.) –– It's been more than 50 years since scientists discovered that the single-celled organism Tetrahymena thermophila has seven sexes. But in all that time, they've never known how each cell's sex, or "mating type," is determined.
Now they do.
Individuals who had taken a type of drug commonly used to treat Type 2 diabetes showed abnormalities in the pancreas, including cell proliferation, that may be associated with an increased risk of neuroendocrine tumors, according to a new study by researchers from UCLA and the University of Florida. Their findings were published online March 22 in the journal Diabetes.
A new UCLA-led study suggests a way to predict when a woman will have her final menstrual period. The findings, published in the April issue of the peer-reviewed Journal of Clinical Endocrinology and Metabolism, could help women and physicians gauge the onset of menopause-related bone loss, which generally begins a year prior to the last period.
German researchers Alexander Riedel (Natural History Museum Karlsruhe) and Michael Balke (Zoological State Collection Munich), know this well, being experts for faunas of remote tropical countries such as the wilderness of New Guinea.
DETROIT – While the number of people – especially women – who have a minimally invasive procedure to remove kidney stones has risen in recent years, so has the rate of complications related to the surgery, according to a published study by Henry Ford Hospital.
The research, from Khurshid R. Ghani, M.D., of Henry Ford Hospital's Vattikuti Urology Institute, appears in the current issue of Journal of Urology.
Researchers at Moffitt Cancer Center and colleagues at the University of Florida studied health care providers to determine the factors associated with disparities in Human Papillomavirus (HPV) vaccination among girls, ages 9 to 17, from low-income families. They found that physician vaccination strategies and the type of practice play a role in whether or not girls were vaccinated.
The study results were published in the Feb. 1 issue of Cancer.
University of Montreal researchers have discovered a novel molecular mechanism that can potentially slows the aging process and may prevent the progression of some cancers. In the March 23 online edition of the prestigious journal Aging Cell, scientists from the University of Montreal explain how they found that the antidiabetic drug metformin reduces the production of inflammatory cytokines that normally activate the immune system, but if overproduced can lead to pathological inflammation, a condition that both damages tissues in aging and favors tumor growth.
The sequencing and assembly of the genome of the mountain pine beetle, Dendroctonus ponderosae, is published online this week in Genome Biology. The species is native to North America, where it is currently wreaking havoc in an area of forest ten times larger than previous outbreaks. This paper determines genes that may be involved in colonizing the trees, such as enzymes for degrading plant cell walls, and identifies potential sex chromosomes in the beetle.
