Researchers ferret out a flu clue

Researchers have discovered a link between ferrets and humans which could lead to improved therapies for a range of diseases

2014-12-18
(Press-News.org) Research that provides a new understanding as to why ferrets are similar to humans is set to have major implications for the development of novel drugs and treatment strategies.

Published in the prestigious journal Nature Communications, the research is a collaboration between Professor Michael Jennings and other researchers from the Institute for Glycomics, Griffith University and collaborators at the University of Queensland and the University of Adelaide.

The team has shown for the first time that ferrets share a mutation that was previously thought to be unique to humans, among the mammals. This helps to explain why the molecular characteristics of ferrets so uniquely mimic human susceptibility, severity and transmission of influenza A virus strains.

Professor Michael Jennings, Deputy Director of the Institute for Glycomics, says these findings open up a completely novel approach to tackling human diseases from influenza through to cancer.

"For over 80 years we've known that ferrets are uniquely susceptible to human influenza A virus, but the precise reason was unknown," Professor Jennings said.

"We have shown that ferrets have a mutation in a gene required to make a crucial sugar called sialic acid. Most animals can make two types of sialic acid. Ferrets, like humans can make only one. Different flu strains have preferences for the type of sialic acid they bind to cause infection. Because ferrets can only make the human form of this sugar, they are naturally "humanized" for the receptors recognised by human strains of the flu virus."

Tailor-made cancer treatments? New cell culture technique paves the way

2014-12-18
ANN ARBOR--In a development that could lead to a deeper understanding of cancer and better early-stage treatment of the disease, University of Michigan researchers have devised a reliable way to grow a certain type of cancer cells from patients outside the body for study. The new technique is more than three times as effective as previous methods. Researchers say it's a major step forward in the study of circulating tumor cells, which are shed from tumors and circulate through the blood of cancer patients. They're believed to cause metastasis, the spread of cancer ...

The Greenland Ice Sheet: Now in HD

The Greenland Ice Sheet: Now in HD
2014-12-18
SAN FRANCISCO--The Greenland Ice Sheet is ready for its close-up. The highest-resolution satellite images ever taken of that region are making their debut. And while each individual pixel represents only one moment in time, taken together they show the ice sheet as a kind of living body--flowing, crumbling and melting out to sea. The Ohio State University has partnered with the Polar Geospatial Center at the University of Minnesota to turn images captured by DigitalGlobe's Worldview-1 and 2 satellites into publicly available elevation maps that researchers can use to ...

Expectant fathers experience prenatal hormone changes

2014-12-18
ANN ARBOR--Impending fatherhood can lower two hormones--testosterone and estradiol--for men, even before their babies are born, a new University of Michigan study found. Other studies indicate that men's hormones change once they become fathers, and there is some evidence that this is a function of a decline after the child's birth. The new U-M study is the first to show that the decline may begin even earlier, during the transition to fatherhood, said Robin Edelstein, the study's lead author. "We don't yet know exactly why men's hormones are changing," said Edelstein, ...

Report: Clearing rainforests distorts wind and water, packs climate wallop beyond carbon

2014-12-18
LONDON, UK (18 December 2014)--A new study released today presents powerful evidence that clearing trees not only spews carbon into the atmosphere, but also triggers major shifts in rainfall and increased temperatures worldwide that are just as potent as those caused by current carbon pollution. Further, the study finds that future agricultural productivity across the globe is at risk from deforestation-induced warming and altered rainfall patterns. The report, "Effects of Tropical Deforestation on Climate Change and Agriculture," published today in Nature Climate Change ...

Electron spin could be the key to high-temperature superconductivity

2014-12-18
Cuprates are materials with great promise for achieving superconductivity at higher temperatures (-120oC). This could mean low-cost electricity without energy loss. Intense research has focused on understanding the physics of cuprates in the hope that we can develop room-temperature superconductors. EPFL scientists have now used a cutting-edge technique to uncover the way cuprates become superconductors. Their work is published in Nature Communications. Conventional superconductors are materials that conduct electricity with no electrical resistance under temperatures ...

Study shows epinephrine auto-injectors and asthma inhalers used incorrectly

2014-12-18
ARLINGTON HEIGHTS, Ill. (December 18, 2014) - Millions of Americans with severe allergies and asthma are prescribed medical devices to help relieve symptoms and sometimes, to treat potentially fatal allergic reactions. Unfortunately, very few people use their prescribed medical devices properly - even if they think they know how. According to a new study published in the Annals of Allergy, Asthma and Immunology, the scientific publication of the American College of Allergy, Asthma and Immunology (ACAAI), misuse of epinephrine auto-injectors has been documented in cases ...

Moms of food-allergic kids need dietician's support

2014-12-18
ARLINGTON HEIGHTS, Ill. (December 18, 2014) - Discovering your child has a severe food allergy can be a terrible shock. Even more stressful can be determining what foods your child can and cannot eat, and constructing a new diet which might eliminate entire categories of foods. According to a new study published in the Annals of Allergy, Asthma and Immunology, the scientific publication of the American College of Allergy, Asthma and Immunology (ACAAI), providing parents with detailed, individual advice from a dietician is a key component of effective food allergy care. "We ...

How does prostate cancer form?

2014-12-18
(PHILADELPHIA) - Prostate cancer affects more than 23,000 men this year in the USA however the individual genes that initiate prostate cancer formation are poorly understood. Finding an enzyme that regulates this process could provide excellent new prevention approaches for this common malignancy. Sirtuin enzymes have been implicated in neurodegeneration, obesity, heart disease, and cancer. Research published online Thursday (Dec 18th) in The American Journal of Pathology show the loss of one of sirtuin (SIRT1) drives the formation of early prostate cancer (prostatic intraepithelial ...

Subtle but important memory function affected by preterm birth

2014-12-18
A new study has found that children born prematurely show differences in a subtle but important aspect of memory: the ability to form and retrieve memories about context, such as what, when, and where something happened. This type of memory is important, but can be missed on the usual set of direct assessments. The new research suggests that it may be valuable to find targeted ways to help strengthen this aspect of memory in children born preterm. The study also found that the hippocampus region of the brain is smaller in children born prematurely. This is the part of ...

The quality of parent-infant relationships and early childhood shyness predict teen anxiety

2014-12-18
Infants who frequently react to unfamiliar objects, people, and situations by becoming afraid and withdrawing are referred to as having a behaviorally inhibited temperament. As these infants grow up, many continue to be inhibited or reticent when they experience new things, including meeting new people. Inhibited children are more likely than their peers to develop anxiety problems, especially social anxiety, as they get older. A new longitudinal study has found that behavioral inhibition that persists across early childhood is associated with social anxiety in adolescence, ...
