A study by Rice University/Baylor College of Medicine found that areas with more vascular surgeons have lower amputation rates and more bypass surgery performed. The disease affects 8-12 million people and is a major cause of amputations, especially in diabetics.
Mayo Clinic researchers report a new mechanism behind thiopurine metabolism, a protein deficit caused by misfolded proteins that disrupts enzyme function. The discovery offers promising new directions for predicting genetic changes and altering drug effects.
Researchers have developed tools to study sea level change and its driving forces. The largest factor contributing to sea level rise is changes in ice coverage, accounting for about 220 feet of sea level.
Researchers at the University of Pennsylvania School of Medicine have determined how serotonin decreases sensitivity to light and its role in maintaining circadian rhythm. The study suggests that serotonin may play a role in seasonal affective disorder (SAD) and other mood disorders.
NASA's new satellite measurements provide a reference for changes in ocean height, allowing scientists to better predict sea level rise and its causes. The data suggests that ice melting is the largest likely factor in global sea level change.
Researchers simulate sensor web technique to track pollution transport and improve forecast accuracy. The technology coordinates observations from satellites, airborne instruments, and ground-based stations to provide alerts days in advance for vulnerable populations.
A population-based case control study found that PSA screening of asymptomatic men significantly reduces the risk of metastatic prostate cancer. The researchers discovered a 35% protective effect, even among men not screened regularly.
Dr. Irene Pepperberg's research shows an African grey parrot, Alex, understands the absence of a numerical quantity by using the label 'none', challenging current understanding of avian cognition. This discovery also holds potential for teaching autistic and learning-disabled children
A new study reveals that earthquake recurrence times exhibit self-similarity, with smaller clusters of earthquakes grouped together within larger clusters. This critical phenomenon may improve risk estimation by showing a clear statistical dependence between earthquakes.
Physicists propose new class of time machines that avoid difficulties inherent in other models. Researchers also analyze lateral vibrations to control friction and crack propagation in thin films. The horizontal Brazil nut effect is studied, showing grain migration to center or edge based on size and density.
The 'Deep Impact' collision released tens of thousands of tons of material, enough to bury a football field under 30 feet of comet dust. Scientists are analyzing X-ray data to better understand the evaporation process on comets and their interaction with solar wind.
Researchers analyzed identical male twin pairs with differing lifestyles to study the impact of diet and exercise on LDL cholesterol. The study found a strong correlation between twins' responses to diet changes, highlighting the importance of genes in determining individual responses to dietary fat.
Researchers identified a specific amino acid modification in Keap1 as the critical step that triggers increased Nrf2 and protective protein production, potentially leading to cancer prevention. The study's findings suggest that targeting this amino acid could lead to new cancer-fighting drugs.
Doctors with poor communications skills struggle to engage patients due to computer placement, whereas those with good skills use eye contact and posture. The study emphasizes the importance of placing computers on moveable arms for optimal eye contact between doctors and patients.
Gene amplification is a common process in cancer cells that can lead to increased production of genes like MITF, which regulates tissue development and tumor progression. Researchers found an over-expression of MITF in melanoma tissue microarrays using the AQUA technology, correlating with decreased patient survival.
Scientists at NASA have developed a way to process radar data from the Tropical Rainfall Measuring Mission (TRMM) satellite, providing 3D snapshots of hurricanes. This allows forecasters to access information on heavy rainfall rates and cloud heights within three hours, helping them make more accurate forecasts.
Menzies Research Institute director Professor Foote awarded $17.5 million US grant to expand genetic research program on malaria. He will investigate how humans' immune systems fight malaria by infecting lab mice with rare genetic mutations.
