New research on flu vaccination in PLoS Medicine

Two studies published in PLOS Medicine show that increasing flu vaccination rates can decrease the burden of influenza. A universal immunization program in Ontario led to reductions in flu-related deaths, hospitalizations, and emergency department visits compared to other provinces.

Glutamate: Too much of a good thing in schizophrenia?

Researchers found that deleting the gene for glutamate transporter EAAT1 leads to increased responses to NMDA receptor antagonist MK-801, resulting in schizophrenia-like features in mice. The study suggests a promising new class of glutamate-targeting antipsychotic treatments may help correct these abnormalities.

Wildflower declines in Thoreau's Concord woods are due to climate changes

Researchers at Boston University and Harvard University have found that wildflowers in Thoreau's Concord woods are declining due to climate change. The study, which analyzed phylogenetic patterns of species loss, reveals that species with the ability to track short-term temperature changes have faired better under recent warming trends.

King Solomon's (copper) mines?

Archaeologists have uncovered evidence of ancient copper-production center at Khirbat en-Nahas, dating back to the 10th century BCE, pushing back archaeological chronology by three centuries. The discovery supports biblical narratives and raises questions about the historicity of King David and Solomon's rule.

Scientists identify new gene responsible for puberty disorders

Researchers at Medical College of Georgia identified a new gene, chromodomain helicase DNA binding protein 7 (CHD7), responsible for some puberty disorders, including idiopathic hypogonadotropic hypogonadism (IHH) and Kallmann syndrome. The study found that CHD7 mutations account for about 6% of IHH and Kallmann syndrome cases.

Progress toward new storage media

Researchers have created reliable nanopatterns of a spin-transition compound on silicon oxide chips, paving the way for new molecular storage media. The development uses special unconventional micro- and nanolithographic techniques to print neutral iron(II) complexes onto silicon wafers in the form of fine lines.

American Society of Agronomy presents awards

The American Society of Agronomy has recognized five individuals with prestigious awards for their excellence in agronomic education, extension, and service. Lee Burras received the Agronomic Resident Education Award for his outstanding teaching skills, while William J. Cox was honored with the Agronomic Extension Education Award for h...

Catching quakes with laptops

The project uses laptops with built-in accelerometer chips to detect tremors, allowing for faster earthquake detection and more accurate location of strong motions. With many sensors, it's possible to provide several seconds of warning before an earthquake hits neighboring regions.

Diabetes treatment becomes more complex, costly

The study reveals that diabetes prescriptions increased, with more medications prescribed per patient and higher costs, from $6.7 billion in 2001 to $12.5 billion in 2007. Insulin use decreased, while the use of newer drugs like glitazones increased.

Effects of anesthesia on the heart

Researchers created a first-ever genetic animal model to study anesthetic agents' effects on individuals genetically predisposed to arrhythmia and sudden cardiac death. The study found that some anesthetics trigger arrhythmias, particularly in models with long QT syndrome.

New brain link as cause of schizophrenia

Researchers at Newcastle University have identified a key brain link that causes schizophrenia, revealing NMDA receptors play a critical role in modifying brain oscillations. Optimizing receptor function could lead to new treatment approaches for the mental illness, affecting one in 100 people.

Rheumatoid arthritis rising among women

Rheumatoid arthritis incidence and prevalence are on the rise among women in the US, with a 54% increase in female cases from 36 to 54 per 100,000 annually, according to a Mayo Clinic study. Researchers believe an environmental factor may be contributing to this trend, which could indicate a need for further research.

Making a difference in minority health
