Large Study Reveals PTSD Has Strong Genetic Component Like Other Psychiatric Disorders

Post-traumatic stress disorder (PTSD) is one of the most common psychiatric disorders, affecting some 8 million adults at some point in their lifetime in the United States. Despite this, it is not clear why only some people who experience a traumatic event develop PTSD. Some researchers have suggested that the disorder is only a social construct, but previous studies have hinted that genetics plays a role. A new study identifies a clear biological basis for PTSD.

New Diagnostic Criteria May Enable Earlier Detection of Cognitive Impairment in Women

Women make up two-thirds of patients with Alzheimer’s disease — so why is it that women are less likely than men to be diagnosed with its precursor, amnestic mild cognitive impairment (aMCI)? This was the question guiding a new study by University of California San Diego School of Medicine researchers studying how the life-long female advantage in verbal memory performance might be masking early symptoms of dementia in women.

Water + air + electricity = hydrogen peroxide

The production of hydrogen peroxide can be much safer and simpler through a process developed at Rice University.

A reactor developed by Haotian Wang and his colleagues at Rice’s Brown School of Engineering requires only air, water and electricity to make the valuable chemical in the desired concentration and high purity.

Needle-Free Flu Vaccine Patch Effective in Early Study

A new needle-free flu vaccine patch revved up the immune system much like a traditional flu shot without any negative side effects, according to a study published in the Journal of Investigative Dermatology. Though the research is in the early stages (the patch hasn’t been tested in humans), it’s an important step toward a technology that could replace needle-based vaccination methods that require administration by health care workers and biohazard waste removal.
