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.

What happens when you explode a chemical bond?

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.

Physicists find first possible 3D quantum spin liquid

Cerium pyrochlore is first to qualify as long-sought state of matter

There’s no known way to prove a three-dimensional “quantum spin liquid” exists, so Rice University physicists and their collaborators did the next best thing: They showed their single crystals of cerium zirconium pyrochlore had the right stuff to qualify as the first possible 3D version of the long-sought state of matter.
