It sounds bonkers that a tick bite might make meat eaters allergic to their steaks and ribs, but it’s true. Now new research has added a potential twist: The source of this tick-related sensitivity to red meat may also be linked to coronary artery disease.
A bite from the lone star tick, Amblyomma americanum, can trigger antibodies to a sugar called alpha-gal, found in many mammals but...
Mouth wounds heal faster than injuries to other parts of the skin, and now scientists are learning how the mouth performs its speedy repairs.
Some master regulators of gene activity work overtime in the mouth to heal wounds without scarring, researchers report July 25 in Science Translational Medicine. Those regulators — proteins known as SOX2, PITX1, PITX2 and PAX9 — are active in skin...

Genetic modifications to a plant that makes artemisinin, a key compound used in malaria drugs, more than tripled the amount of the ingredient naturally produced in leaves.
Previous attempts to genetically engineer Artemisia annua to increase the yield of artemisinin had failed. So Kexuan Tang, a plant scientist at Shanghai Jiao Tong University, and colleagues determined A. annua’s entire...
Tattoos may have staying power because of a hand off between generations of immune cells known as macrophages, say a group of French researchers.
If true, this would overturn notions that tattoo ink persists in connective tissue or in long-lasting macrophages.
Immunologist Sandrine Henri of the Immunology Center of Marseille-Luminy, in France, and colleagues tattooed mice tails...
Sometimes an old fight needs a new hero. With the United States in the midst of a tough flu season — and with evidence from Australia that the current flu shot is only 10 percent effective against the strains responsible for most illnesses — a different approach to flu vaccine development may do the trick.
Vaccines traditionally protect against illness by stimulating antibodies to block...
