Expect 6,000 more Australian deaths if pollution rises to 'safe' threshold

A study by Queensland University of Technology found that increasing pollution levels just below the current 'safe' standards would cause an estimated 6,000 extra deaths annually in Australia. The health statistician calls for thorough cost-benefit analyses to inform decision-making on new infrastructure projects.

Genetic test would help 'cut bowel cancer spread'

A genetic test for Lynch Syndrome could help reduce the risk of bowel, womb, and ovarian cancers in families. The test would identify individuals who are at higher risk and provide them with risk-reducing measures such as more intensive surveillance to spot recurrences and new cancers early.

New discovery approach accelerates identification of potential cancer treatments

Researchers at the University of Michigan have developed a new approach to discovering potential cancer treatments, replicating the native environment of cancer cells. They identified an antibody, 4C3, that stops breast cancer tumor growth in animal models and are investigating its potential as a treatment for human patients.

Developing countries should enroll medical and nursing students from rural areas

A new study suggests that targeted admission of medical and nursing students from rural areas could provide a solution to the current Ebola outbreak in western Africa. The study found that students from rural areas are more likely to want to pursue rural careers, making them ideal candidates for recruitment.

The cultural side of science communication

A new Northwestern University study highlights the importance of considering cultural differences in science communication, finding that media often reflects cultural orientations and assumptions. The research reveals that Native Americans tend to see themselves as part of nature, while European-Americans view humans as apart from it.

The Lancet Diabetes & Endocrinology: Genetic study casts further doubt that vitamin D prevents the development of type 2 diabetes

A large genetic study has found no evidence of a causal link between vitamin D levels and the development of type 2 diabetes. The study, conducted by scientists at the University of Cambridge, examined the genes that control blood levels of vitamin D and found no association with the risk of developing type 2 diabetes.

This week from AGU: Measuring Antarctic ice loss, Indian Ocean program, Oregon landslides

Researchers used fiber-optic cables to measure Antarctic ice loss in real-time, with potential implications for global sea levels. In another study, scientists explored the Indian Ocean's legacy and future research efforts. Meanwhile, Oregon landslides were found to be more susceptible to catastrophic failure during earthquakes.

Rehospitalization in younger patients

A large cohort study found that younger patients (18-64) have higher readmission rates for heart failure than older adults, but lower rates for myocardial infarction and pneumonia. After adjusting for confounding factors, the study suggests a post-hospital syndrome in both age groups, with similar timing and reasons for readmission

Pollution linked to lethal sea turtle tumors

A new study published in PeerJ found that pollution in urban and farm runoff in Hawaii causes tumors in endangered sea turtles. The researchers discovered that high levels of nitrogen in the runoff promote the formation of tumors on the animals' eyes, flippers, and internal organs.

Expect 6,000 more Australian deaths if pollution rises to 'safe' threshold

A QUT expert warns Australian governments that increasing pollution to just below existing standards would cause thousands of additional deaths each year. The health statistician's analysis reveals the devastating impact of pollution on human life, highlighting the need for thorough cost-benefit analyses in environmental studies.

New blood test determines whether you have or are likely to get cancer

Researchers developed a new blood test called the lymphocyte genome sensitivity (LGS) test, which can detect some cancers earlier than ever before. The test analyzes white blood cells exposed to UVA light and measures their DNA damage, allowing for early cancer detection and identifying those at risk of developing cancer.

University of Alberta researchers explain 38-year-old mystery of the heart

Researchers at the University of Alberta have explained how a key protein in the heart changes in heart failure, shedding light on the molecular mechanisms behind this complex condition. By studying troponin I, they discovered that increased calcium sensitivity actually helps trigger contraction, despite slower relaxation.

Tree killers, yes, fire starters, no: Mountain pine beetles get a bad rap, study says

A recent study by the University of Wisconsin-Madison found that mountain pine beetles contribute little to the ecological severity of fires in the Northern Rocky Mountains. The researchers tested six wildfires that affected over 75,000 acres and found no significant link between beetle outbreaks and fire severity.

Genetic modifier affects colon tumor formation

Researchers discovered that a genetic modifier called Pla2g2a can protect against colon tumors in mice, which could have significant implications for cancer research and treatment. The study found that mice with the resistant allele of Pla2g2a had fewer tumors than those with the sensitive allele.
