A study of more than 13 million hours of data, collected from light sensors worn by 89,000 people, has found exposure to bright nights and dark days is associated with an increased risk of death.

Sleep apnea, a common yet underdiagnosed sleep disorder, contributes to the development of dementia among adults -- particularly women, a new study suggests. At every age level, women with known or suspected sleep apnea were more likely than men to be diagnosed with dementia. A common yet underdiagnosed sleep disorder contributes to the development of

As critical responders, macrophages can perceive helpful biotechnology as threats. If not created with the right materials or mechanical forces, these devices can trigger an immune response that can cause inflammation, scar tissue or device failure. Macrophage cells are the immune system's frontline soldiers, early on the scene to protect the body from foreign invaders.

CBT for insomnia significantly reduces postpartum depression symptoms, directly and indirectly, by improving mood and alleviating insomnia throughout treatment. While many people believe that poor sleep during pregnancy is inevitable, new research has determined that cognitive behavioral therapy for insomnia (CBTi) while pregnant can not only improve sleep patterns but also address postpartum depression. Researchers

New research is exploring low-cost, non-invasive ways to diagnose Barrett's esophagus, a condition associated with deadly esophageal cancer, to find effective strategies to identify patients with this condition.

Men and adolescent boys are increasingly at risk of resorting to the dangerous use of anabolic steroids in a bid to achieve the desired muscular build modeled on social media, warn body image experts. A new review that focused specifically on men found that exposure to social media posts depicting ideal muscular male bodies is

Young people with severe obesity who underwent weight-loss surgery at age 19 or younger continued to see sustained weight loss and resolution of common obesity-related comorbidities 10 years later, according to results from a large clinical study. Young people with severe obesity who underwent weight-loss surgery at age 19 or younger continued to see sustained

Chronic, low-level lead poisoning is a major risk factor for cardiovascular disease in adults and cognitive deficits in children, even at levels previously thought to be safe, Low-level lead poisoning is a risk factor for preterm. Annually 5.5 million deaths from cardiovascular disease attributed to low-level lead poisoning; accounts for a loss of 765 million

New research has found inflammatory markers in the blood of long COVID patients which could explain why many experience ongoing cardiovascular issues. University of Queensland-led research has found inflammatory markers in the blood of long COVID patients which could explain why many experience ongoing cardiovascular issues. Associate Professor Kirsty Short said the team set out

An important new study has demonstrated that a combination therapy can slow cognitive decline in older adults at risk for dementia. An important new study led by the Centre for Addiction and Mental Health (CAMH), and with partnership across several Toronto Dementia Research Alliance (TDRA) sites -- Baycrest, Sunnybrook Health Science Centre, Unity Health Toronto

Using state-of-the-art technology, researchers have identified several specific steps needed for CRISPR to become active and perform its gene editing function. These preclinical findings could lead to improved designs for CRISPR-based gene editing. CRISPR/Cas9 is a gene editing tool that has revolutionized biomedical research and led to the first FDA-approved CRISPR-based gene therapy. However, until

In the search for more sustainable uses of cellulose, scientists have developed a production method for a nanofibrous cellulose matrix, which has the potential to replace non-renewable industrial even in biomedical applications. The efficient use of cellulose -- the primary plant scaffold and a major natural building block -- could address many issues associated with
