Scientists succeed in filming organs and joints in real time using magnetic resonance imaging
"Please hold absolutely still": This instruction is crucial for patients being examined by magnetic resonance imaging (MRI). It is the only way to obtain clear images for diagnosis. Up to now, it was therefore almost impossible to image moving organs using MRI. Researchers in Germany have now succeeded in significantly reducing the time required for recording images -- to just one fiftieth of a second. With this breakthrough, the dynamics of organs and joints can be filmed "live" for the first time: movements of the eye and jaw as well as the bending knee and the beating heart.
New Norwegian earplug solution to a deafening problem
Some 600 cases of noise-induced hearing impairment are reported by the Norwegian petroleum industry every year. A new, intelligent earplug is now set to alleviate the problem. The international energy company Statoil ASA has led efforts to further develop a combined hearing protection and communication product for use on offshore platforms. The QUIETPRO hearing protection and communication device was originally developed for military use by the Trondheim-based company Nacre AS. The company’s customers include the United States Army, which uses QUIETPRO devices in armoured vehicles.
Social isolation worsens cardiac arrest effects on heart regulation
A new study in mice shows how social support can help minimize some of the worst physical damages to the brain caused by a heart attack. From cell death to depressive symptoms to regulation of the heart, mice that lived with a partner after a heart attack suffered less damage than did similar mice that were housed alone.
Stopping colon cancer by activating anti-cancer genes
Researchers have succeeded in decoding the genetic key that gives particular intestinal cells their identity. With this knowledge of the complex network of genes the researchers now hope to stop colon cancer by activating special anti-cancer genes.
Better treatment of atrial fibrillation and its risks
The earlier that patients who suffer from atrial fibrillation obtain the correct treatment, the lower is the risk of serious secondary effects such as stroke. New research from Sweden shows that a well-established measurement score can easily assess the risks for this patient group.
First clear evidence of organized feasting by early humans
Community feasting is one of the most universal and important social behaviors found among humans. Now, scientists have found the earliest clear evidence of organized feasting, from a burial site dated about 12,000 years ago. These remains represent the first archaeological verification that human feasting began before the advent of agriculture.
People at 'intermediate risk' of heart disease with elevated hsCRP benefit from statin therapy, study suggests
People at intermediate risk of cardiovascular disease who have high levels of high sensitivity C-reactive protein, a blood marker for inflammation, could benefit from cholesterol-lowering therapy even if their cholesterol is already at desirable levels. Data indicates that people with only a 5 percent to 20 percent risk of having heart disease in the next 10 years, but who have high levels of hsCRP could reduce the risk of heart attack and stroke by more than 40 percent.
Tuning into cell signals that tell where sensory organs will form inside the ear
Researchers have tracked a cell-to-cell pathway that designates the future location of the ear's sensory organs in embryonic mice. The scientists succeeded in activating this signal more widely across the embronic tissue that forms the inner ear. Patches of sensory structures began growing in spots where they don't normally appear. The results suggest an avenue for further investigation in restoring hearing loss and correcting balance problems from nerve damage in the inner ear.
Researchers develop new laboratory cell lines to study treatment for anaplastic thyroid cancer
To their deep dismay, researchers discovered several years ago that laboratory samples of anaplastic thyroid cancer they were using to help them find new treatments for this lethal disease were probably some other kind of cancer. It quickly became evident that the situation in their lab was common throughout the world. Up to half of the cell lines that were supposed to originate from patients with this rare thyroid cancer were either colon or melanoma cancer. So, with the cooperation of many researchers nationwide, the researchers set out to create a new set of laboratory ATC cells, derived from tumors donated by patients.
Research produces tools to study stallions' subfertility
Subfertility of breeding stallions -- meaning the horses are less able to sire foals -- is a well-recognized problem that has caused multi-million-dollar losses in the equine industry, experts say. Researchers believe they are making progress in solving the problem by using an approach that might provide tools and resources necessary to study subfertility without causing stallions the angst of providing testicular samples for testing.
Over 50? You probably prefer negative stories about young people
When given a choice, older people prefer to read negative news, rather than positive news, about young adults, a new study suggests. In fact, older readers who chose to read negative stories about young individuals actually get a small boost in their self-esteem, according to the results.
'Stocky dragon' dinosaur, relative of Velociraptor, terrorized Late Cretaceous Europe
Paleontologists have discovered that a close relative of Velociraptor hunted the dwarfed inhabitants of Late Cretaceous Europe, an island landscape largely isolated from nearby continents. While island animals tend to be smaller and more primitive than their continental cousins, the theropod Balaur bondoc was as large as its relatives on other parts of the globe and demonstrated advanced adaptations including fused bones and two terrifyingly large claws on each hind foot.
Body mass index and thrombogenic factors in newly menopausal women
A study of a subset of women in the Kronos Early Estrogen Prevention Study suggests that as BMI increases, so do platelet reactivity and thrombogenic microvesicles and activated protein C in the blood -- all of which contribute to the formation of atherothrombosis and associated cardiovascular events.
