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.
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.
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.
High schools where students are more connected to peers and adult staff, and share strong relationships with the same adults, have lower rates of suicide attempts, according to a new study published by the Journal of Child Psychology and Psychiatry.
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.
A potential treatment for polycystic kidney disease – a genetic disorder that causes the kidneys to swell with multiple cysts and can eventually lead to organ failure – has shown promising results in animal testing.
Exercising several times a week may delay brain deterioration in people at high risk for Alzheimer’s disease, according to a study that scientists say merits further research to establish whether fitness can affect the progression of dementia.
Researchers at the Ohio State University Center for Automotive Research have created new computer models to predict the life and performance of batteries that could power some passenger airplanes – a step forward for cleaner, more efficient air travel.
Cybersecurity researchers have discovered vulnerabilities in the backend systems that feed content and advertising to smartphone applications through a network of cloud-based servers that most users probably don’t even know exists.
On bright summer days, the sunlight all around us is breaking bad by breaking bonds. Chemical bonds.
Ultraviolet light shatters the links between atoms in the DNA of our skin cells, potentially causing cancer. UV light also breaks oxygen bonds, eventually creating ozone, and cleaves hydrogen off other molecules to leave behind free radicals that can damage tissue.
