Smart sensors listen to healing wounds

Researchers at Heriot-Watt University are creating tiny electronic sensors that can hear what is going on below the bandages.

Wound care costs the UK's health services billions of pounds a year.

While some types of specialist wound dressings are available, the principal method of finding out how well a wound is healing has been to remove the bandages and take a look.

The team is led by Dr Michael Crichton, assistant professor in biomedical engineering at Heriot-Watt.

He says he wants to bring data into the process. "If we can put a sensor on the surface of the tissue, around a wound or across a wound, can we actually measure what's happening?

"If we can do that, that will tell us if a wound is likely to be going in one way or another.

"And if we can measure it over time, then we don't need to keep on opening up a wound and saying, 'is it getting better or is it getting worse?'."

But what does a healthy wound sound like? Before they can know that, the researchers must investigate how skin behaves when it is cut.

Social Contagion, Not Mental Illness, Fuels Gun Violence

After the recent pair of mass shootings in El Paso, Texas and Dayton, Ohio, the collective attention of America’s ire has once again landed squarely on the topic of gun control.

In a predictable turn, gun-rights advocates have speculated that the real cause for these shootings is mental illness and violent video games and movies. Meanwhile, gun-control advocates are pushing for expansive background checks and bans on the sale of certain guns or accessories.

But as the discussion heats up, the American Psychological Association (APA) issued a declaration that mental illness should not be in the spotlight after incidents like these.

They say scapegoating mental health issues overlooks research and ignores decades of investigation that points to other causes.

Lost in translation: Researchers discover translator gene may play a role in disease

When researchers and clinicians investigate the genome's relation to disease, they have traditionally focused on mutations in the code for proteins. But now researchers at Western University have shown that the genes encoding tRNAs can also have mutations that cause the code to be misread, and in greater numbers than previously thought.

Think of it like a translator app on your phone -- if it has errors in its software, the output is going to be all wrong, even if the original text is correct.

"This actually changes the way we think about the genetic code," said lead author Mathew Berg, a PhD Candidate at Western's Schulich School of Medicine & Dentistry. "We have shown that variation in tRNA has the potential to lead to a protein being made improperly, which can lead to misfolding and malfunction of the protein."

The research team, led by Schulich Medicine & Dentistry Professors Christopher Brandl, Robert Hegele and Patrick O'Donoghue, say this is significant because many human diseases like Alzheimer's disease and diseases of the heart muscle are linked to misfolded proteins.

Choose the alternative which presents a reasonable conclusion from the news presented below.

The lack of effective tools to control Aedes aegypti mosquito populations has resulted in the continued expansion of dengue virus, Zika virus and CHIKV. Some recent attempts at curbing mosquito populations have resulted in reductions in mosquito density but not reductions in human disease. AGO traps consist of a pail with hay and water to attract eggbearing female mosquitos and a sticky lining to which the insects adhere. Previous studies have shown that placing three AGO traps outside of 85% of homes in a community resulted in an 80% reduction in adult mosquito populations but the studies did not assess rates of mosquito-borne diseases in humans.

In the new work, Tyler Sharp, of the CDC, and colleagues randomly selected 290 households in Puerto Rican communities that had AGO trap interventions and 349 households in communities without AGO traps. 175 household members from intervention communities and 152 from non-intervention communities were enrolled in the study. Blood samples were collected from each participant to detect CHIKV infection and surveys recorded demographic information as well as data on mosquito repellent and bed net use and frequency of mosquito bites.

A total of 114 participants (34.9%) were seropositive for CHIKV. Among people who spent most of their daytime hours inside the community they lived in, 10.3% were seropositive for CHIKV in communities with AGO traps whereas 48.7% were positive for CHIKV in communities without traps.
