Orientation without a master plan

Studies show that when learning objects in an open space, spatial memory is accessed step-by-step, while environmental spaces require more time to recall objects from neighboring corridors. This research has implications for understanding navigation and the neuronal basis of wayfinding.

Research shows it may be time to abandon dreaded digital rectal exam

A recent study suggests that the digital rectal exam (DRE) is no longer necessary for prostate cancer screening due to its limited effectiveness and potential risks. The DRE has been shown to capture an additional small population of men with significant prostate cancer, but it also subjects a large number of men to unnecessary tests.

Nanotechnology supports treatment of malignant melanoma

Researchers use nanosensors to detect genetic mutations in tissue samples from patients with malignant melanoma. This enables the identification of specific mutations and targeted treatment, significantly extending patients' life expectancy. The new method detects changes quickly and easily using coated microcantilevers.

ESMO rewards outstanding oncologists

The European Society for Medical Oncology (ESMO) has awarded four distinguished recipients for their outstanding contributions to cancer treatment and research. Alberto Sobrero received the ESMO Award for his world-renowned research on gastrointestinal cancer, while Sir Richard Peto was recognized for his important contributions to bre...

A new angle on anxiety

A new study from Boston Children's Hospital reveals that specific neurons in the hypothalamus play a central role in triggering anxiety. Blocking these neurons selectively erased natural fears in mice, suggesting a potential more effective treatment for anxiety and other psychiatric disorders.

Grassland tuned to present suffers in a warmer future

The Jasper Ridge Global Change Experiment found that warming had negative effects on plant growth, while elevated atmospheric carbon dioxide showed no consistent response. Plant growth peaked when precipitation was close to historic averages, highlighting the need for ambitious climate action to stabilize warming and protect ecosystems.

Study: Earth's carbon points to planetary smashup

A study by Rice University researchers proposes that the origin of Earth's volatile elements, including carbon, can be explained by a massive collision between Earth and an embryonic planet similar to Mercury. This collision may have led to the exclusion of carbon from Earth's core and its incorporation into the silicate mantle.
