New research suggests that eliminating the nasal virus that causes the symptoms may reduce allergic inflammation and open a new treatment avenue for the millions of people suffering from allergic rhinitis. Study: Treatment of allergic rhinitis using ribavirin spray to eliminate commensal viruses in the nose. Image credit: Cinefootage Visuals / Shutterstock In a recent study published in the journal Signal transduction and targeted therapyresearchers investigated how viruses present in the nasal cavity contribute to the development of allergic rhinitis (AR). In a small phase 2 trial, researchers found that removing commensal viruses from the nose with ribavirin nasal spray…

People who frequently experience a deep sense of inner emptiness often struggle to maintain a solid identity and regulate their emotions. A recent study using smartphones has mapped how emptiness fluctuates from day to day and relates to broader personality challenges. The study was published in Personality Disorders: Theory, Research, and Treatment. Mental health professionals often hear patients describe feeling a deep emptiness within themselves, believing that nothing matters, and lacking a sense of who they are. Currently, the most widely used psychiatric diagnostic manual lists emptiness as the only symptom of borderline personality disorder. The manual also limits this…

New research published in scientific progress Researchers suggest that vibrating small magnets implanted within the muscles of amputated limbs can restore a natural sense of hand coordination. These findings provide evidence that the brain perceives movements as synchronized whole-hand movements rather than isolated finger twitches. This research offers a promising path toward advanced prosthetic limbs that allow users to feel what they are doing without relying entirely on vision. For amputees, operating a prosthesis often feels mechanical and disconnected. This happens because the surgery separates the muscles from the joints, disrupting the natural communication between the body and the brain.…

We work with our partners to continually review and improve our results.Some residents in northeastern Ontario are questioning a new law that would allow the prime minister’s cabinet to use pesticides even if Health Canada deems them unsafe.Bill C-30, passed on June 18, gives the Cabinet the power to license pesticides that it believes will benefit the national economy or food security. The bill does not clearly define what the national economic or food security interests are. Camille Tremblay-Beaulieu, co-executive director…

A recent study led by researchers at the University of the Sunshine Coast (UniSC) suggests that high-intensity interval training (HIIT) may be one of the most effective ways for older people to reduce body fat while preserving muscle mass. This study compared different exercise intensities in healthy older adults and found that all levels of exercise resulted in some degree of fat loss. However, only HIIT helped participants maintain lean muscles. “We found that high-, moderate- and low-intensity exercise all lead to moderate fat loss, but only HIIT maintains lean muscle,” said lead author and exercise physiologist Dr Grace Rose…

A new study reveals that age, biological sex, and cognitive ability correspond to distinct patterns in the brain waves that ripple through your mind at night. Analyzing data from nearly 2,000 healthy people, researchers found that the architecture of rest changes with age and is subtly different for men and women. The study was published in the journal Frontiers in Sleep. As a person spends the night, the brain cycles through different stages. Humans alternate between rapid eye movement sleep, in which they usually have vivid dreams, and several stages of non-rapid eye movement sleep. The latter includes light rest…

Widely used pesticides may pose a greater threat to brain health than previously realized. UCLA Health researchers report that long-term exposure to chlorpyrifos near the home is associated with a more than 2.5-fold increased risk of developing Parkinson’s disease. This research molecular neurodegenerationcombined evidence from hundreds of people with laboratory experiments designed to reveal exactly how pesticides affect the brain. The results suggest that chlorpyrifos can damage important nerve cells involved in movement and may play a direct role in the development of Parkinson’s disease. Why is Parkinson’s disease important? Parkinson’s disease is a progressive neurological disease that affects approximately…

Astronomers led by Northwestern University have discovered an unusual feature around the famous “pink planet”: a sky filled with salty clouds. The ancient world, known for its pinkish haze, has remained one of astronomy’s enduring mysteries for more than a decade. One of the coldest planetary-mass companions ever imaged directly, the object is so faint that scientists have struggled to analyze the light from Earth. Now, observations from the James Webb Space Telescope (JWST) reveal an atmosphere filled with exotic chemicals and clouds unlike anything seen before. The discovery provides some of the first direct evidence that salt clouds may…

A 12-month longitudinal study of adolescents found that those who had experienced more negative events in their lives tended to have more severe depressive symptoms. This association was particularly pronounced regarding negative self-evaluation. Girls who experienced more negative life events reported greater increases in negative self-evaluation symptoms than boys. The paper is scientific report. Depression is a mental health disorder characterized by persistent feelings of sadness, emptiness, or loss of interest in activities. It affects how a person feels, thinks, acts, and functions in daily life. Common symptoms include low mood, fatigue, difficulty concentrating, trouble sleeping, changes in appetite, and…

Children with Attention Deficit Hyperactivity Disorder, who have a clear divide between verbal and nonverbal intelligence, face significant challenges in self-control and concentration. These mental gaps coincide with reduced blood flow to the front of the brain during tasks that require impulse control. The results were published in the magazine NeuroImage. Attention-deficit hyperactivity disorder is one of the most common neurodevelopmental disorders in school-age children. Its main characteristics include an inability to maintain concentration, physical restlessness, or impulsive behavior. These symptoms often result from weaknesses in executive function. Executive function functions as the brain’s management system, organizing thoughts, regulating emotions,…
