Risk Of Developing Deep Vein Thrombosis During A Flight Is Often Overestimated, According to Some Experts
The risk of developing deep vein thrombosis during a long flight is often overestimated. According to some researchers, this condition is very unlikely in healthy travelers. When people wear a...
Motor Molecules Use Random Walks To Make Deliveries In Living Cells
Cells rely on tiny molecular motors to deliver cargo, such as mRNA and organelles, within the cell. The critical nature of this transport system is evidenced by the fact that...
'Long-haired' water moulds are the most virulent
The water mould Saprolegnia can cause skin disease in salmon during its freshwater phase. The mould attacks both fish and eggs and has at times caused great economic loss for...
Genetic marker linked to problem behaviours in adults with developmental disabilities
A common variation of the gene involved in regulating serotonin and norepinephrine in the brain may be linked to problem behaviours in adults with developmental and intellectual disabilities, new research...
Tomato find could feed millions
Australian researchers have discovered how to create better quality fruits and vegetables with higher yield and longer shelf life.
Cold virus used in cystic fibrosis study
CHAPEL HILL, N.C., July 21 (UPI) -- Using a common cold virus to deliver a corrected gene to cystic fibrosis cells restores normal function to lung tissue, researchers in...
Listeriosis probe calls for better equipment, more inspections
Manufacturers should be required to design easy-to-clean meat-processing equipment that limits the spread of bacteria, says a newly released report on last summer's deadly listeriosis outbreak.
Skin-like tissue developed from human embryonic stem cells
Dental and tissue engineering researchers at Tufts University School of Dental Medicine and the Sackler School of Graduate Biomedical Sciences at Tufts have harnessed the pluripotency of human embryonic stem...
Research team seeks to unravel flatworm regeneration
Planarian flatworms are only a few millimetres up to a few centimetres in length, live in freshwater and are the object of intense research, because they possess the extraordinary ability...
Trout key to university's cancer studies
CORVALLIS, Ore., July 21 (UPI) -- Trout are better models for cancer research than mice or rats, a leading researcher at Oregon State University said.
New DNA Vaccine Inhibits Deadly Skin Cancer In Mice
A new DNA vaccine inhibited malignant melanoma, a deadly form of skin cancer, in mice by eliciting antibodies that target a gastrin-releasing peptide which is known to play a key...
Animal experiments in numbers
There are more experiments on animals in the UK than ever before. Get the full data Figures out today show the largest rise in the use of animals in medical research since modern...
Bluebirds returning to parts of Florida
TAMPA, Fla., July 21 (UPI) -- The once endangered Eastern bluebird is making a comeback of sorts in parts of Florida with nearly 100 birds nesting east of Tampa,...
Brain's Center For Perceiving 3-D Motion Is Identified
Neuroscientists have now pinpointed where and how the brain processes 3-D motion using specially developed computer displays and an fMRI (functional magnetic resonance imaging) machine to scan the brain.
Ethiopian Government Celebrates Rinderpest Eradication
A menace to the African cattle population for more than a century, the World Organisation for Animal Health (OIE) has declared rinderpest eradicated in Ethiopia. Ethiopia, which grappled with the...
Tension in axons is essential for synaptic signalling, researchers report
Every time a neurone sends a signal - to move a muscle or form a memory, for example - tiny membrane-bound compartments, called vesicles, dump neurotransmitters into the synapse between...
New life histories emerge for invasive wasps, magnify ecological harm
A switch from annual to multiyear colonies and a willingness to feed just about any prey to their young have allowed invasive yellowjacket wasps to disrupt native populations of insects...
Genes that let creepy-crawlies survive a deep freeze
Arctic springtails (Megaphorura arctica) survive freezing temperatures by dehydrating themselves before the coldest weather sets in. Researchers writing in the open access journal BMC Genomics have identified a suite of...
Human movement plays critical role in understanding disease transmission
To control mosquito-borne diseases like dengue, researchers need to look at the behavior of people, not just the insect that transmits the disease, according to new research by Steven Stoddard...
Uterine cells produce their own oestrogen during pregnancy
For decades, scientists assumed that the ovary alone produced steroid hormones during pregnancy. In a new study in mice, however, researchers demonstrate that once an embryo attaches to the uterine...
Heart disease: Research off the beating patch
It is an amazing sight: What looks like a tiny beating heart is actually a piece of synthetic, gauze-like mesh, barely the size of a fingernail, floating in a Petri...
Growing Sea Lamprey Embryos Dramatically Alter Genomes, Discard Millions Of Units Of DNA
Sea lampreys, which arose from the jawless fish that first appeared a half-billion years ago, dramatically remodel their genomes during embryonic development. This is believed to be the first recorded...
Milwaukee jaguar may be hope of species

Researchers look to imprinted genes for clues to foetal growth restriction in cloned swine
Researchers at North Carolina State University have found that intrauterine growth restriction (IUGR), which results in low birth weight and long-term deleterious health effects in cloned swine, is linked to...
Muscular protein bond -- strongest yet found in nature
A research collaboration between Munich-based biophysicists and a structural biologist in Hamburg (Germany) is helping to explain why our muscles, and those of other animals, don't simply fall apart under...
