Vibrating 2D materials

Scientists have successfully determined the strength of exciton-phonon coupling in 2D materials at room temperature, a crucial step towards optimizing their applications. This breakthrough was achieved using a novel method called coherent 2D microscopy, which combines high spatial resolution with femtosecond time resolution.

Learning by observation reduces cognitive bias, research suggests

New research suggests that observing others' decision-making can teach people to make better decisions themselves. The study, co-authored by Professor Irene Scopelliti, tested the effectiveness of a new debiasing training strategy and reports first evidence that watching others make decisions can improve our own decision making.

Patient education program with mental health component reduces cardiovascular disease risks

A 12-month patient education program that integrated mental health information significantly reduced cardiovascular disease risks, improving measures such as fasting blood sugar, LDL cholesterol, and BMI. Patients who received the program maintained most of these improvements six months later.

One dose of COVID-19 vaccine provokes strong immune response in those previously infected

A recent study published in Eurosurveillance found that one dose of the Pfizer vaccine triggers a strong immune response in people who have previously been infected with SARS-CoV-2. The researchers also observed similar responses across multi-ethnic groups, suggesting that vaccination priority for those previously infected may not be n...

Chemotherapy and hearing loss: Until now, an unquantified risk

The largest multi-center study of cisplatin-induced hearing loss reveals that permanent hearing loss occurs in 20-90% of patients, with higher doses and vincristine use increasing risk. The study establishes benchmarks for the prevalence of hearing loss and provides insights into how adjusting dosing approaches can minimize side effects.

Heart failure cases soar globally

Global heart failure cases rose from 33.5 million in 1990 to 64.3 million in 2017, mainly due to increased risk factors such as hypertension, diabetes, and obesity. The prevalence of heart failure decreased only in high-income countries, while it increased in low- and middle-income countries.

Vaporised crusts of Earth-like planets found in dying stars

University of Warwick astronomers detect lithium and potassium in the atmospheres of four nearby white dwarf stars, revealing remnants of rocky planet crusts. The chemical composition of these crusts is similar to Earth's continental crust, providing a glimpse of the planets that may have orbited these dying stars billions of years ago.

Gene variants increase risk of Addison's disease

A large-scale genetic study found that variants of nine genes increase the risk of developing Addison's disease, a rare autoimmune disorder. The study identified specific gene variants associated with the disease, including the AIRE gene, which plays a crucial role in immune system function.

Monitoring the body's fat burning by breath

A research group from Tohoku University has developed a compact, low-cost device that can measure acetone gas concentration in exhaled air to monitor fat burning. The device uses ultraviolet light to gauge the concentration with high accuracy, allowing for non-invasive monitoring and optimization of metabolism.
