Using a bioinformatics and experimental approach, scientists have found that rendering mitochondria resistant to damage can halt diseases caused by amyloid toxicity, such as Alzheimer's disease.

What's that smell? The advantage of sniffing

Posted: 06 Dec 2017 09:25 AM PST

Breathe in through your nose, and chances are you will feel the air coming in and also smell something nearby. Researchers have discovered how these sensations are kept separate and why sniffing can help identify odors, two problems that have puzzled scientists for years. The study used a system in mice that systematically controls airflow and odor delivery.

Psychosis incidence highly variable internationally

Rates of psychosis can be close to eight times higher in some regions compared to others, finds a new study.

Alzheimer's damage in mice reduced with compound that targets APOE gene

Posted: 06 Dec 2017 09:25 AM PST

People who carry the APOE4 genetic variant face a substantial risk for developing Alzheimer's disease. Now, researchers have identified a compound that targets the APOE protein in the brains of mice and protects against damage induced by the Alzheimer's protein amyloid beta. The findings indicate that APOE could potentially be a real target for treatment or prevention.

New method helps identify causal mechanisms in depression

Posted: 06 Dec 2017 09:25 AM PST

People with major depressive disorder have alterations in the activity and connectivity of brain systems underlying reward and memory, according to a new study. The findings provide clues as to which regions of the brain could be at the root of symptoms, such as reduced happiness and pleasure, in depression.

What makes a happy working mom?

Posted: 06 Dec 2017 09:25 AM PST

A happy working mom feels competent in interacting with her child, experiences a sense of freedom and choice in her actions, while having a warm and affectionate relationship with her baby. She is also not too hard on herself about how she is faring as a mother.

Youth who experience violent victimization seek intimate relationships at an earlier age

Posted: 06 Dec 2017 06:22 AM PST

Experiencing violence as an adolescent leads to early romantic relationships and cohabitating, research concludes. On average, they found that victimized youth entered romantic relationships nine months earlier than non-victimized youth.

Is laughter the greatest medicine for cancer patients?

Posted: 06 Dec 2017 06:18 AM PST

Spontaneous humor is used and appreciated by people with cancer and can be a helpful way of dealing with distressing, taboo or embarrassing circumstances, research shows.

Research finds new ways to fight the opioid crisis

Posted: 06 Dec 2017 06:06 AM PST

In the US alone, more than 2 million people struggle with opioid use disorders. Opioids, often prescribed as pain medications, have now become the country's leading cause of drug overdose. But scientists are identifying ways to help combat the epidemic, which include getting people treatment faster, developing safer opioids, and helping patients choose appropriate treatment.

Alarming amounts of noise demand ways to silence noisy hospital environments

Posted: 06 Dec 2017 06:06 AM PST

Spending a night in the hospital is not only stressful, but also loud. The constant beeps, whirrs and alarms ascend to a cacophony that produces anything but a relaxing, restful environment. Researchers summarize the limited number of studies available on hospital noise and discuss the different approaches health care facilities are taking to bring restful repose to patients across the country.

Disorders of the voice can affect a politician's success

Posted: 06 Dec 2017 06:06 AM PST

The acoustics of political speech are known to be a powerful influencer of voter preferences, but vocal disorders can change the qualities of a person's speech, and voice scientists have found that this alters politicians' perceived charisma.

Lack of sleep could cause mood disorders in teens

Posted: 06 Dec 2017 06:06 AM PST

Chronic sleep deprivation -- which can involve staying up late, and waking up early for work or school -- has become a way of life for both kids and adults, especially with the increasing use of phones and tablets late into the night. But this social jet lag poses some serious health and mental health risks: new research finds that for teenagers, even a short period of sleep restriction could, over the long-term, raise their risk for depression and addiction.

New hope for waitlisted patients addicted to opioids

Posted: 06 Dec 2017 06:06 AM PST

As the opioid crisis continues to escalate, the number of people who need treatment for their dependency on heroin or prescription pain killers far exceeds the capacity of available treatment programs. People seeking treatment can wait months or even years for spots in clinics or with certified doctors -- and while they wait, they risk becoming infected with HIV or hepatitis, as well as dying from an overdose.

US and Norwegian trials compare treatment options for opioid dependence

Posted: 06 Dec 2017 06:06 AM PST

The current opioid epidemic is destroying lives, families, and communities. Medication is widely considered to be the most effective treatment, but far too few people who could benefit are actually treated.

Want to listen better? Lend a right ear

Posted: 06 Dec 2017 06:06 AM PST

Listening requires sensitive hearing and the ability to process information into cohesive meaning. Add everyday background noise and constant interruptions, and the ability to comprehend what is heard becomes that much more difficult. Audiology researchers have found that in such demanding environments, both children and adults depend more on their right ear for processing and retaining what they hear.

Serious risk of mental health crisis in Yemen, say experts

Posted: 05 Dec 2017 06:16 AM PST

Yemenis face serious mental health risks, but the issue is being neglected. In a new study, the researchers reveal how serious the risk to mental health is in Yemen. Yet, mental health services in Yemen are few, and there is little research on the effects of the war on the mental health of the population. The paper also analyzes the long-term costs of failing to respond.

Experimental drug blocks toxic ion flow linked to Alzheimer's disease

Posted: 05 Dec 2017 06:15 AM PST

A new small-molecule drug can restore brain function and memory in a mouse model of Alzheimer's disease. The molecule, called anle138b, works by stopping toxic ion flow in the brain that is known to trigger nerve cell death. Scientists envision that this drug could be used to treat Alzheimer's and other neurodegenerative diseases such as Parkinson's and ALS.
