Ambulance workers at risk of post-traumatic stress disorder
These were the findings of a study published today, Friday 10 September, in the British Journal of Clinical Psychology, by clinical psychologists Sue Clohessy and Professor Anke Ehlers of Oxford University. view more (1999-09-03)
Small molecule interactions were central to the origin of life
In an important new paper forthcoming in the June issue of The Quarterly Review of Biology, Robert Shapiro (New York University) argues against the widely held theory that the origin of life began with the spontaneous appearance of a large, replicating molecule such as RNA. view more (2006-05-17)
Ragweed Research Is Nothing to Sneeze At
To a person with a pollen allergy, an 18-acre ragweed field sounds like a sneezy, red-eyed zone of misery. But to two environmental engineering researchers at Johns Hopkins, the parcel presented a rare and valuable opportunity to learn how the troublesome weeds grow, reproduce and scatter their pollen under varying weather conditions. view more (2007-09-25)
Purdue scientists see biochemistry's future - with quantum physics
Chemists who have trouble predicting how some large, complex biological molecules will react with others may soon have a solution from the world of computational quantum physics. view more (2005-09-16)
Top ten contact dermatitis allergens identified in Mayo Clinic study
A new Mayo Clinic study reveals the most common causes of allergic contact dermatitis, a skin inflammation resulting in swollen, reddened and itchy skin due to direct contact with an allergen. view more (2006-03-06)
Hurricane aftermath: Infectious disease threats from common, not exotic, diseases
In the wake of Katrina, the public health threats from infectious diseases in hurricane-devastated areas are more likely to come from milder, more common infections rather than exotic diseases. These common infections can often be prevented using simple hygiene measures and a little common sense. view more (2005-09-14)
Worm's hunger response provides clue to eating disorders
In research that may have implications for studying eating disorders in humans, a worm the size of a pinhead is helping researchers at UT Southwestern Medical Center unravel the mechanisms of hunger. view more (2006-04-05)
Rehydrate - your RNA needs it
Water, that molecule-of-all-trades, is famous for its roles in shaping the Earth, sustaining living creatures and serving as a universal solvent. view more (2006-08-23)
Scientists capture the speediest ever motion in a molecule
The fastest ever observations of protons moving within a molecule open a new window on fundamental processes in chemistry and biology, researchers report today in the journal Science. view more (2006-03-03)
Friendly bacteria reduce hospital infections
A probiotic bacterium, Lactobacillus plantarum 299, has been used to out-compete the dangerous bacteria that cause respiratory illness in ventilated patients. view more (2008-11-06)
Volcanic aerosol clouds and gases lead to ozone destruction
Volcanic eruptions destroy ozone and create 'mini-ozone holes', according to two new studies by researchers at the Universities of Cambridge and Oxford. view more (2006-11-09)
A step forward in the fight against bacterial infections
Bacterial infections can strike anyone, and they can sometimes be fatal. Because more and more bacteria are becoming resistant to the pre-eminent remedy; antibiotics; the search for new remedies against bacterial infections is in high gear. view more (2006-02-02)
Physicists step closer to understanding origin of the universe
The world's largest particle detector is nearing completion following the construction of its 'endcap' at the University of Liverpool. view more (2006-02-22)
Unlocking biological secrets: Cornell scientists build 'nano-keys' to bind cell receptors and trigger allergic reactions
The tumblers of life continue to click as Cornell University researchers have fabricated a set of "nano-keys" on the molecular scale to interact with receptors on cell membranes and trigger larger-scale responses within cells - such as the release of histamines in an allergic response. view more (2006-02-17)
New radiation technique can greatly reduce painful skin burns in women with breast cancer
Breast cancer patients who undergo a new radiation technique called intensity modulated radiation therapy (IMRT) after surgery are three times less likely to have severe skin reactions from the treatment compared to standard radiation therapy. view more (2006-11-07)
AAAAI, ACAAI identify new recommendations for sinusitis diagnosis and management
Sinusitis is one of the most diagnosed diseases in the United States, affecting approximately 16% of the adult population, and is responsible for nearly $5.8 billion in health care costs annually, according to an updated practice parameter. view more (2005-11-30)
Allergy season: Cigarettes to the rescue?
Everyone knows that smoking can kill you, but did you know that it may help with your allergies? A new study shows that cigarette smoke can prevent allergies by decreasing the reaction of immune cells to allergens. view more (2009-05-15)
White blood cells in lung produce histamine seen in allergies
In a surprise finding, scientists have discovered that histamine, the inflammatory compound released during allergic reactions that causes runny nose, watery eyes, and wheezing, can be produced in large amounts in the lung by neutrophils, the white blood cells that are the major component of pus. view more (2007-01-15)
'Allergy cells' can aggravate cancer and psoriasis
The body's mast cells are mainly associated with allergic reaction in the way they release histamine and other inflammatory substances. view more (2006-09-11)
Halting histamine action means hallelujah for hay fever sufferers
In allergic diseases such as asthma, hay fever, and rhinitis an allergen stimulates the release of antibodies that attach themselves to mast cells causing these cells to release histamine, which can cause symptoms like itching of the nose, skin and eyes, sneezing, and wheezing. view more (2006-05-05)
