Age tied to spread of rectal cancer to lymph nodes

Researchers found that the risk of rectal cancer spreading to lymph nodes increases with age, with younger patients being more likely to have affected nodes. The study suggests that doctors should hunt aggressively for lymph node involvement in younger patients.

Test developed to detect early-stage diseases with naked eye

Scientists at Imperial College London developed a prototype ultra-sensitive sensor that can detect biomarkers for diseases like prostate cancer and HIV with the naked eye. The technology is ten times more sensitive than current gold standard methods and could be significantly cheaper to administer.

Influenza vaccine may reduce risk of heart disease and death

The influenza vaccine has been shown to reduce the risk of major cardiac events such as strokes, heart attacks, and cardiac deaths by approximately 50 percent. A similar trend was seen for reducing death from any cause, with a reduction of around 40 percent.

Key discovered to how chemotherapy drug causes heart failure

A study by University of Texas M.D. Anderson Cancer Center reveals that doxorubicin's cardiotoxicity is linked to the Top2b enzyme, which drives DNA damage and affects heart muscle metabolism. The discovery could lead to a simple blood test to predict sensitivity to the drug.

Primates' brains make visual maps using triangular grids

Researchers at Emory University have identified grid cells in rhesus monkeys' brains, which fire in repeating triangular patterns as they explore visual scenes. This finding has implications for understanding how humans form mental maps of the world and may help explain why disorientation is a common symptom of Alzheimer's disease.

Researchers look beyond space and time to cope with quantum theory

Researchers propose an inequality that probes the role of signals in quantum predictions, exposing how they challenge Einstein's theory of relativity. The test, feasible in the near future, will measure a single number, potentially revealing faster-than-light communication or infinitely fast influences.

Uncertainty of future South Pacific Island rainfall explained

A new study by Matthew Widlansky and Axel Timmermann found that rainfall projections for South Pacific islands are highly uncertain due to two competing effects of greenhouse warming. The 'wet gets wetter' mechanism suggests heavier rainfall, while the 'warmest gets wetter' mechanism predicts drying in some regions.

Drop in testosterone tied to prostate cancer recurrence

Researchers found that men whose testosterone fell following radiation therapy were more likely to experience an increase in prostate-specific antigen (PSA), often indicating cancer recurrence. This discovery may lead doctors to use testosterone levels as a guide for treatment decisions.
