Salt apparently affects allergic immune reactions. A team working with Professor Christina Zielinski at the Technical University of Munich has demonstrated in cell cultures that salt leads to the formation of Th2 cells. These immune cells are active in allergic conditions such as atopic dermatitis. The team also detected elevated salt concentrations in the skin of patients.
Atopic dermatitis, also known as allergic eczema, affects nearly 20 percent of children, 30 percent of whom also have food allergies. Scientists have found that children with both atopic dermatitis and food allergy have structural and molecular differences in top layers of skin near the eczema lesions, whereas children with atopic dermatitis alone don't. Defining these differences may help identif

Lungcancern, den cancer som dödar flest i Sverige, ökar nu snabbt bland dem som aldrig rökt. I dag drabbas fler kvinnor än män av denna cancerform, men då den typiska lungcancerpatienten är en äldre man som röker har vården svårt att upptäcka just kvinnorna som inte röker men som ändå drabbas. Mia Rajalin är en av dem, och hon tvingades söka vård 13 gånger innan cancern upptäcktes.

Astronomers led by Mark Showalter of the SETI Institute discovered it using the Hubble Space Telescope combined with an innovative method to track dim and tiny objects as they orbit. Because the object is so tiny, there's still a lot astronomers
The Pentagon and federal intelligence agencies have said that climate change is a threat. Now, the White House is planning a panel to study whether or not that is true.
Researchers have discovered that the ancient technique of heating metal to create vibrant colors creates a nanostructured surface that acts as a perfect light absorber. Perfect light absorbers—materials that absorb more than 99% of a certain color—can be used for sensing, solar panels, anti-counterfeiting and stealth technologies.
Researchers have documented a group of tanner crabs vigorously feeding at a methane seep on the seafloor off British Columbia—one of the first times a commercially harvested species has been seen using this energy source.
The planets may get top billing in the solar system, but they are far outnumbered by the moons. There are hundreds, and they come in all kinds of varieties, like a cosmic tray of assorted chocolates. Our own moon is a barren, rocky world coated with craters. Enceladus, of Saturn, and Europa, of Jupiter, are frozen , shrouded in a thick layer of ice with a liquid-ocean center. Io, another moon of
Teaching in the United States was once considered a career for men. Then the profession's gender composition shifted dramatically around the mid-19th century, when the country's public-school system was born. As schoolhouse doors opened to children of all social classes and genders, so too did the education profession. By the late 1880s, women made up a majority—63 percent—of all the country's te

Since plastic carryout bags were introduced in the 1960s, people have used trillions of them, and, for the most part, thrown them away. And whether they're sitting in a landfill, hung up in a tree limb or floating around the ocean, the bags don't biodegrade, and they're not going away anytime soon. They're free to consumers, convenient and cheap for stores to use. But they have joined billions of
The How to Train Your Dragon series occupies a particularly vital spot in the world of animated fables. Other hit films such as Kung Fu Panda and Spider-Man: Into the Spider-Verse are stirring tales of heroism and maturity; recent Pixar classics such as Coco and Inside Out examined the bonds of the family unit through the eyes of kids on the verge of growing up.

A frosty mug of beer or ruby-red glass of wine just wouldn't be the same if the liquid was murky or gritty. That's why producers of alcoholic beverages usually filter them. But in a study appearing in ACS' Journal of Agricultural and Food Chemistry, researchers report that a material often used as a filter could be transferring heavy metals such as arsenic to beer and wine. They also found ways to
Implantable pacemakers have without doubt altered modern medicine, saving countless lives by regulating heart rhythm. But they have one serious shortcoming: Their batteries last only five to 12 years, at which point they have to be replaced surgically. Now, researchers have surmounted this issue by designing a pacemaker powered by the energy of heartbeats, according to a report in ACS Nano. The de

Next to rising temperatures and dwindling oxygen concentrations, acidification is one of the major threats to marine life due to the changing global climate. Carbon dioxide concentrations in the atmosphere are rising and the ocean therefore takes up increasing amounts of CO2 from the atmosphere, as well. The reaction of carbon dioxide with the water forms carbonic acid, the pH is lowered—the ocean

Large forest fires occur with increasing frequency globally, and their consequences grow more severe and destructive. Climate change and human activity are influencing the capacity of ecosystems and the life forms that inhabit them to recover from forest fires. However, the actions to recover the affected environment can be an opportunity to recover lost natural values.
