As technology advances, photonic systems are gaining ground over traditional electronics, using light to transmit and process information more efficiently. One such optical system is laser beam scanning (LBS), where laser beams are rapidly steered to scan, sense, or display information. This technology is used in applications ranging from barcode scanners at grocery stores to laser projectors in light shows. To process a wider range of signals or enable full-color output, these systems utilize multiplexers that merge the red, green, and blue (RGB) laser beams into a single beam. Traditionally, this was achieved ...

Two new studies find that leaders are less likely to empower followers who raise concerns about workplace decisions, even though these “challenging voice” employees play a critical role in highlighting problems and identifying solutions. The studies also outline what drives these decisions. “We know that employee performance improves and employee turnover declines when employees are empowered – that’s good,” says Bradley Kirkman, co-author of a paper on the two studies. “We also know that having employees who use challenging voice are also beneficial to the bottom line – because ...

COLUMBUS, Ohio – Living within miles of the ocean breeze may be linked to a longer life, but you shouldn’t count on the same benefits if you live in a riverside city, suggests a recent study. Researchers from The Ohio State University analyzed population data — including life expectancy — in more than 66,000 census tracts throughout the U.S. and compared it based on proximity to waterways. Their study was published online in the journal Environmental Research. A correlation between longer life expectancy and water was clear for those who live within about 30 miles of an ocean or gulf. But for those who live in urban settings and near an inland ...

Key Takeaways Among 3 million surgical patients, 0.5% developed alcohol withdrawal syndrome (AWS), with 0.2% experiencing severe delirium tremens (DT).  AWS was associated with a 37% higher risk of complications, including respiratory failure and sepsis, and a 40% increased mortality risk if DT occurred. Hospital stays were 5 days longer, and costs rose by $10,000 per patient with AWS, totaling $165 million in excess costs nationwide.  CHICAGO — Patients who develop alcohol withdrawal syndrome (AWS) after major surgery face significantly higher risks of complications, longer hospital stays, and increased health care costs, ...

About The Study: This randomized clinical trial found that among older adults at risk of cognitive decline and dementia, a structured, higher-intensity intervention of regular moderate-to-high-intensity physical exercise, adherence to the MIND diet, cognitive challenge and social engagement, and cardiovascular health monitoring had a statistically significant greater benefit on global cognition compared with an unstructured, self-guided intervention. Known as the US Study to Protect Brain Health Through Lifestyle ...

Detecting early rising Parkinson’s disease (PD) symptoms could improve treatment outcomes by enabling earlier treatment interventions. In a new eNeuro paper, Daniil Berezhnoi, from Georgetown University, and colleagues used machine learning technology to detect subtle, early rising behavioral changes in mouse models of PD. The researchers also evaluated whether Levodopa, the primary approved treatment for PD, can effectively treat these symptoms.  Berezhnoi et al. used a previously developed motion sequencing platform to evaluate movements of different ...

Previous expectations can influence how much pain people eventually feel. These expectations can be shaped by external cues or by verbal information from clinicians about how treatments might relieve pain. Led by Lauren Atlas, researchers from the National Institute of Health explored if and how distinct ways of shaping expectations differentially influence physically hurtful experiences.  In their JNeurosci paper, the researchers present their findings from 40 healthy volunteers who rated how hurt they were following painful ...

A groundbreaking international study, recently published in Health Data Science, analyzed objective sleep data from 88,461 adults in the UK Biobank and found significant associations between sleep traits and 172 diseases. The research, led by teams from Peking University and Army Medical University, highlights sleep regularity—such as bedtime consistency and circadian rhythm stability—as an underrecognized but critical factor in disease risk. Using actigraphy data over an average of 6.8 years, researchers identified that 92 diseases had over 20% of their risk attributable to poor sleep behavior. Notably, irregular ...

Simple technology that harnesses ultraviolet light to ‘zap’ airborne viruses has been shown to significantly lower the number of respiratory infections in aged care facilities, paving the way for smarter infection control. Adapted by scientists from Flinders Health and Medical Research Institute  (FHMRI) and SAHMRI, the technology is based on using germicidal ultraviolet (GUV) appliances which purify the air with UV-C light rays and deactivate harmful micro-organisms like viruses and bacteria. The new study published in JAMA Internal Medicine trialled commercially-available GUV appliances in aged care facilities ...

Researchers at the University of Tokyo explored how female body odor can influence behaviors in men. They found certain scent compounds in female body odor increased during ovulation and can subtly influence how men feel. When these scents were added to armpit odor samples, men rated them as more pleasant and faces associated with the samples as more attractive. The scents also seemed to reduce stress. The team states this is not evidence of pheromones in humans, but that smell might subtly shape how we people interact. While they’re a common staple of pop culture, especially in romantic comedies, pheromones, behavior-altering ...

Phages are seen as a promising alternative treatment to antibiotics. Unpicking how bacteria protect themselves, and how phages might overcome these defences, could be a significant step in defeating antibiotic resistant bacteria. Phages, ...

Cambridge, MA – Scientists often seek new materials derived from polymers. Rather than starting a polymer search from scratch, they save time and money by blending existing polymers to achieve desired properties. But identifying the best blend is a thorny problem. Not only is there a practically limitless number of potential combinations, but polymers interact in complex ways, so the properties of a new blend are challenging to predict. To accelerate the discovery of new materials, MIT researchers ...
