Why do autoimmune diseases affect more women than men?
New research published in Cell points to the female chromosomes. Since females have two X chromosomes, a strand of molecules wrap around certain sections to shut them off, ensuring that the cells don’t make too many proteins which can lead to death. However, scientists believe these molecules may also be triggering strong autoimmune responses. The research was done in mice.
Diagnosing on the go
Researchers have created a hand-held device that can detect breast cancer, as shown in a new study in the Journal of Vacuum Science and Technology B. The tool mixes a person’s saliva with antibodies that respond to cancer biomarkers. The whole process takes five seconds per sample. Though the initial study uses a small sample size, it shows promising results for the future of early detection of breast cancer. (University of Florida)
Are speech disorders all in your head?
A new study in Neurobiology of Language reveals that brain waves may be able to predict when a person will stutter. Beta waves are associated with thought, action, and reactions. Researchers now have found that these waves are also active when a person stutters. Future studies will reveal if altering this brain activity can reduce the presence of speech impediments. (NYU)
The scientific way to feel less stressed
Jennifer lee is the lead lifestyle counselor at the University of Rochester Medical Center. She says we need to change how we talk about stress and realize that it’s the body’s way of protecting us. To respond better in stressful situations, stop what you’re doing and take a deep breath. Think about how you’re feeling and what’s happening around you. Finally, recognize the source of your stress and how you’re reacting, then allow yourself to move past it. Affirmations, like ‘I can handle discomfort’ or ‘I’m doing my best’ can also be helpful in these situations.
