Blood test may identify lung cancer patients likely to respond to erlotinib

A new blood test has been found to identify patients with advanced non-small-cell lung cancer who are more likely to respond to erlotinib treatment. The test, which analyzes specific 'fingerprints' of a protein called EGFR, showed a significant response rate in patients with good proteomic profiles compared to those with poor profiles.

ARS scientists study effects of grazing on grouse habitat

Agricultural Research Service scientists studied cattle grazing patterns to understand its effect on sagebrush communities and grouse habitats. They found that monitoring the rate of interspace tussock consumption can help preserve grouse habitat by allowing ranchers to move their grazing lands when 40% of these tussocks are consumed.

Molecular imaging can identify a potentially deadly blood vessel condition, research suggests

Research published in The Journal of Nuclear Medicine suggests that molecular imaging using 18F-FDG PET/CT can help diagnose acute and chronic aortic dissection. This non-invasive technique can provide images to determine the difference between acute and chronic dissections, helping doctors decide the best course of treatment.

Water-related conflicts set to escalate

The world's waters are facing increasing pressure due to population growth, urbanization, and pollution, threatening food production and water resources. The Mekong River Basin is a prime example of water-related conflicts escalating over access to hydropower production and its impact on local livelihoods.

Satellites, DNA and dolphins

Researchers used genetic data and oceanographic information from satellites to find two distinct populations of franciscanas in Argentina's coastal waters. The findings suggest that environmental factors, such as water temperature and turbidity, play a significant role in shaping population structure in marine animals.

May 2010 Geology highlights

This study examines the correlation between end-Triassic mass extinction and flood basalt volcanism, as well as the effects of water depth on pumice formation in submarine domes. It also investigates the relationship between climatic conditions and soil erosion during the last glacial cycle.

European innovation tackles power cuts

A new Power Distribution Network Automation System (DINAS) has been developed to automatically locate and diagnose faults in distribution networks, restoring power supply instantly. The system uses advanced technology and algorithms to detect and isolate faults, reducing costs and response times for power companies.

Meta-analysis: Radiotherapy variants improve survival in non-metastatic lung cancer

A new meta-analysis reports that hyperfractionated and accelerated radiotherapy regimens improve overall survival in non-small-cell lung cancer patients by 3% after 5 years. Modified fractionation of radiotherapy also shows benefits for small-cell lung cancer patients, although the difference is not statistically significant.
