Effects of PTSD Symptoms in Police Officers

Police officers are often called to situations that require a quick decision: fire a shot and risk harming, or killing, innocent bystanders; do not fire and there is the potential for being killed in the line of duty.

These decisions often are made in the blink of an eye, making it difficult for any officer to accurately process all of the information. The decisions of police with even minor symptoms of post-traumatic stress disorder (PTSD) might be affected. A new study at the University at Buffalo aims to find out.

Elimination of HIV virus and Cure, GW study

The latest "kick-and-kill" research to eliminate the HIV virus uncovered a potential obstacle in finding a cure. A recent study by researchers at the George Washington University (GW) found that latent HIV reservoirs show resistance to CD8+ T-cells, a type of white blood cell whose primary function is to kill infected cells.

Protein nanofibers and its properties

In a new study, researchers determined a Protein nanofibers often have outstanding properties such as a high stability, biodegradability, or antibacterial effect. Artificially creating these fibers is not easy, much less assigning them specific functions. That and how fibers with new properties can be successfully created.

Genes Could Reveal Death Time of Crime Victims

Dying, it turns out, is not like flipping a switch. Genes keep working for a while after a person dies, and scientists have used that activity in the lab to pinpoint the time of death to within about nine minutes.

During the first 24 hours after death, genetic changes kick in across various human tissues, creating patterns of activity that can be used to roughly predict when someone died, according to the study published in Nature Communications.
