Genetic mutations linked to breast, ovarian cancer may be underestimated

Researchers found that the most accurate method of detecting genetic mutations, direct nucleotide sequence analysis, is also the most expensive and labor-intensive. This method was used correctly to identify all previously identified mutations, while other methods, such as SSCP and CSGE, failed to detect over 20% of the mutations.

Near-death experience remains a mystery

A study of 344 cardiac patients who experienced a near-death experience (NDE) after cardiac arrest found that younger patients were more likely to report NDEs, while deeper experiences were more common among women. Longitudinal follow-up revealed increased beliefs in an afterlife and reduced fear of death among those with NDEs.

Geophysicist studies life in the early solar system

A geophysicist proposes that life on Earth may have originated from microorganisms that could survive in high-temperature environments, such as deep beneath the surface. This theory is supported by evidence of ancient organisms thriving in extreme conditions and laboratory experiments showing that microbes can survive in space.

Modeling human lung cancer

Two conditional mouse models of human lung adenocarcinoma have been developed, shedding new light on the disease's development. The models replicate spontaneous mutations found in human lung cancer, enabling researchers to track cancer progression and test therapeutic agents.

Science Foundation launches special anti-terrorism research initiative; project to engage scientists from former Soviet Union in fight against terrorism

The US CRDF is launching a fast track research competition to engage scientists from the former Soviet Union in the fight against terrorism. The Competition aims to minimize the effects of terrorist acts on civilian populations and will offer support to U.S. industry, scientists, and engineers teamed with researchers from FSU.

Man-made hurricane hits S.C. coast Monday

A team of students and researchers from Clemson University test eight houses in coastal South Carolina to determine the most effective hurricane retrofits. The study uses various methods, including cranes and vacuum chambers, to simulate real-life conditions and evaluate the performance of different retrofit measures.

Institute to counter agricultural terrorism formalized

The Texas A&M University Institute for Countermeasures against Agricultural Bioterrorism aims to develop research tools to prevent and respond to terrorist attacks on agriculture. The institute will utilize cutting-edge technologies such as surveillance networking, satellite imaging, and biotechnology to create a proactive defense system.

Researchers investigate mysteries of the African rift

Researchers are studying the chemical signatures of lavas from the Rift Valley in Turkana to understand the evolution of mantle plumes and how continents split apart. The study suggests that a mantle plume was present in the area 35 million years ago, contributing to the formation of the African Rift Valley.

The lego approach to counter cyber-terrorism: Researchers release computer intrusion detection system with configurable components

The STAT intrusion detection system utilizes real-time packet analysis to identify patterns of attacks, aggregating individual alerts to provide an overall pattern of intrusion. The system's modular design enables centralized monitoring and control, allowing for flexible configuration and response to locally detected intrusions.

Glomerular fibrosis now all the RAGE

A recent study published in the Journal of Clinical Investigation reveals a critical role for RAGE protein in glomerular fibrosis, a major driver of chronic kidney disease. The research sheds light on potential therapeutic targets to mitigate this devastating condition.

Researchers trace dynamics of measles epidemics

Measles researchers used statistical techniques to pinpoint epidemic patterns in cities, revealing a two-year cycle, with larger cities catching on faster. The disease spreads through waves at about 5 kilometers per week, primarily carried by school children.
