Put yourself in someone else’s shoes: What type of perspective makes consumers self-conscious?

Researchers found that people who use an actor's perspective experience stronger joy and excitement but greater pride and guilt when recalling past events. In contrast, observers experience heightened sadness and embarrassment. The study highlights the importance of perspective in shaping emotional experiences.

New hi-tech survey accelerates collection of vaccination data

Researchers used new technologies to collect near-real-time data on vaccination side effects in Scotland, revealing no significant safety issues with the 2009-10 swine flu vaccine. The study adds to evidence supporting the safety of vaccination campaigns and could inform future studies using web-based technology.

Stanford engineers use nanophotonics to reshape on-chip computer data transmission

Researchers at Stanford University have created a single-mode light-emitting diode (LED) that is thousands of times more energy efficient than laser-based systems. The device can transmit data at 10 billion bits per second and operates at room temperature, making it a major step forward for on-chip computer data transmission.

Fossil moths show their true colors

Fossil moths from 47 million years ago had yellow-green wings that may have helped them blend in with leaves to avoid predators. Researchers reconstructed the original colors using mathematical analysis, providing insights into the evolution of color use among lepidopterans.

Cleveland Clinic study: 2 statin drugs similarly effective in reversing coronary heart disease

A Cleveland Clinic study reveals that maximum doses of Crestor and Lipitor are equally effective in reversing atherosclerosis after 24 months of treatment. The trial showed no significant differences between the two drugs in reducing plaque burden, but rosuvastatin was found to lower LDL cholesterol and increase HDL levels.

Stop signal discovered for skin cancer

Researchers at Monash University discovered a gene that helps protect against squamous cell carcinoma, the most common form of skin cancer. The absence of this gene is a profound driver of SCC tumours, leading to unchecked cell growth and cancer.

Vascular risk linked to long-term antiepileptic drug therapy

Researchers found that patients with epilepsy on long-term antiepileptic drugs, especially phenytoin, carbamazepine, and valproic acid, are at increased risk for developing atherosclerosis. The study suggests that newer AEDs like lamotrigine may minimize metabolic disturbances and reduce this risk.

MIT: Mimicking the brain, in silicon

The new chip can simulate the activity of a single brain synapse and capture intracellular processes that underlie many brain functions, including learning and memory. It represents a significant advance in modeling neural functions and could be used to build systems for neural prosthetic devices and artificial intelligence devices.

USC researchers discover key aspect of process that activates breast cancer genes

Researchers at USC's Keck School of Medicine discovered how estrogen activates genes in breast-cancer cells through a protein called TIP60, which recognizes methylation signals in chromatin. This finding builds upon previous work and has broader implications for gene regulation and potentially global significance.

Study finds less invasive CT colonography increases participation in colorectal cancer screening

A study published in The Lancet Oncology found that CT colonography significantly increased participation in colorectal cancer screening, with a more than 50% increase compared to traditional colonoscopy. This non-invasive technique has the potential to positively impact overall patient outcomes and reduce complications and costs.
