A recent study found that motion significantly enhances people's ability to recognize subtle facial expressions, particularly when displayed dynamically rather than statically. The research suggests that motion reveals the temporal characteristics of emotions and improves sensitivity to communication of emotion.
A study found that a rapid increase in PSA levels (PSA velocity) is associated with a higher risk of death from prostate cancer following radiation therapy. Men with low-risk disease and high PSA velocity had a 19% 7-year mortality rate, compared to 0% for those with low PSA velocity.

This finding could potentially help fix problems with pancreatic cells in juvenile (type I) diabetes.
A recent study published in Environmental Microbiology found methylotrophic bacteria present in the mouths of healthy volunteers and those with gum disease, but no association between bacterial levels and bad breath. The discovery may lead to a natural way of reducing smelly breath and feet.
The study found that Medicare beneficiaries received lower rates of preventive services, with strong associations between practice type and revenue from Medicaid. Practices with less than 6% of revenue from Medicaid were more likely to provide certain preventive services, while those with high percentages were less likely.
A study found that 45 out of 500 virtual colonoscopy patients had clinically important extracolonic findings, including kidney cancers and abdominal aortic aneurysms. The study suggests that virtual colonoscopy may be more effective at detecting diseases outside the colon than in the colon.

A study of twins and their partners/friends reveals a strong genetic component to our tendency to seek out people like ourselves. The researchers found that 34% of preference for similar mates was due to shared genes, with the greatest self-similarity seen in more heritable items.
Researchers found that wild-caught mountain chickadees differ from previous species tested by consistently ignoring angular features of their environment and following landmarks. This discovery suggests that animals may be predisposed to navigate by geometry, contradicting prior research.
MR spectroscopy enhances breast imaging by identifying chemical compounds in tumors, leading to increased cancer detection rates (94-100%) and improved accuracy (57%). This adds value to existing MR exams, reducing unnecessary biopsies and improving patient outcomes.
A study found that blood pressure control is suboptimal in older women with hypertension, with only 28% of women in this age group achieving controlled blood pressure. The researchers also noted that treatment rates are high, but the use of cost-effective thiazide diuretics is low.
A study published in BMC Pediatrics finds that active maternal smoking, passive exposure, and even quitting during pregnancy can cause genetic damage in the developing fetus. This damage may have lifelong repercussions for the exposed fetus, affecting survival, birth weight, and susceptibility to disease.
False confessions are a significant issue in law enforcement, with various factors contributing to their occurrence. Research suggests that mandatory videotaping of police interviews and interrogations could help reduce these cases by providing an objective record of the proceedings.
The company will use the investment to accelerate its drug development program for neuropathic pain, a prevalent condition affecting an estimated 45% of diabetics and 75% of those over 70. With a significant worldwide market valued at US$3 billion, Spinifex aims to deliver a novel solution to this unmet medical need.
Researchers have discovered the chemical mechanism behind immunodominance, a process where the immune system targets specific pieces of disease-causing molecules. This understanding could lead to the development of more effective vaccines by targeting areas of pathogens that cannot be changed.
A study found that PSA doubling time, pathological Gleason score, and time from surgery to biochemical recurrence are significant risk factors for prostate-specific death. Patients at high risk can be identified and offered aggressive treatment, while those at low risk can be safely observed.
Researchers at Rensselaer Polytechnic Institute developed a heat spreader that uses phase-change heat process to cool the brain during epileptic seizures. The device, implanted on the neocortex, cools the brain from 38°C to 20°C to render it seizure-free.
A new study from UNC Health Care found that whole-body PET/CT scanners are highly accurate in detecting the spread and recurrence of head and neck cancer. The scans can pick up cancer where none was thought to exist, allowing for more precise biopsies and treatment planning.
Studies reveal high users of primary care are often over-serviced but underserved, and electronic medical records have little impact on diabetes quality of care. In contrast, patients treated with dignity report higher satisfaction, treatment adherence, and receipt of preventive services.
Research reveals that emotionally arousing events activate the brain's amygdala, strengthening connections between neurons and increasing a protein called Arc to store lasting memories. The study shows that the amygdala plays a pivotal role in forming long-term memories.
Hassan Khalil's model will allow for new experimentation in artificial organ control, making experiments more flexible and predictable. The collaboration between UH and the Texas Medical Center fosters collaborations between engineers, doctors, and professionals.
A study of 2,593 cases found that school pesticide exposure led to acute illnesses in children (7.4 cases per million) and adults (27.3 cases per million). The majority of illnesses were associated with insecticides, with integrated pest management programs recommended to prevent such exposures.
The Jefferson Lab FEL has been recognized as one of the top 100 most technologically significant products of 2005. It provides a scaleable path for high laser output power and enables new applications in materials science, national security, and more.
A U of T study published in Free Radical Biology and Medicine found that a single exposure to methamphetamine during pregnancy can cause long-term neurodevelopmental problems. The developing fetus is vulnerable to DNA damage from the drug due to its lack of enzymes protecting it against free radicals.
A recent study found that virtual colonoscopy can detect extracolonic abnormalities in 63% of patients, with clinically important findings detected in 9%. The procedure is potentially cost-effective and can be used to screen for other conditions as well.
