Study uncovers gender roles in physics lab courses

A Cornell University study finds that inquiry-based physics labs, designed to encourage student agency, actually contain gender imbalances and biases when compared to traditional, highly structured labs. The researchers analyzed student behavior in two types of labs and found that men and women take on different roles within groups.

Cold-adapted enzymes can transform at room temperature

Cold-adapted enzymes from low-temperature organisms exhibit distinctive properties that enable them to function in freezing conditions. However, they often stop functioning at around room temperature, until they start melting. Researchers have now explained this phenomenon through extensive computer simulations.

Lymph node metastases form through a wider evolutionary bottleneck than distant metastases

A new study reveals that lymph node and distant metastases develop through different evolutionary mechanisms, with lymph nodes being a genetically highly diverse group. This suggests that metastasis formation in locoregional lymph nodes is comparatively easy and can be achieved by many cells, whereas dissemination to and outgrowth in d...

Battling disease with ultraviolet light

The study aims to develop optical radiation products used in large-scale sanitation processes and create a lamp with both germicidal and lighting elements. Researchers will test different wavelengths of ultraviolet light against coronaviruses like COVID-19.

Evidence insufficient regarding interventions to prevent illicit drug use in children, teens and young adults

The US Preventive Services Task Force has concluded that current evidence is insufficient to make a recommendation regarding primary care-based behavioral counseling interventions to prevent illicit drug use in children, adolescents and young adults. Illicit drug use contributes to the leading causes of death among young people ages 10...

Researchers discover how protein can inhibit cancer development in mice

A new study by the University of Copenhagen's researchers has revealed that the protein PP2A inhibits cancer development in mice by turning off an enzyme called ADAM17. This finding has significant implications for understanding the role of PP2A as a tumour suppressor and exploring potential therapeutic applications.

Novel electric impulses relieve the pain

Researchers at TU Wien and MedUni Vienna have developed a novel method for electric stimulation of the vagus nerve in the ear. A microanatomical study revealed the optimal placement of tiny electrodes to stimulate the nerve, resulting in effective pain relief. The triphasic signal pattern was found to be particularly effective.
