A quantum internet is closer to reality, thanks to this switch

Researchers at Purdue University have addressed an issue that was barring the development of quantum networks. By deploying a programmable switch, they can adjust how much data goes to each user by selecting and redirecting wavelengths of light carrying different data channels. This allows for the increase in users without adding to ph...

Bitter receptor involved in anti-inflammatory effect of resveratrol?

A recent collaborative study has shown that resveratrol's anti-inflammatory properties are mediated by the bitter receptor TAS2R50. The researchers found that this receptor type plays a role in reducing inflammatory markers released by gum cells when treated with surface antigens from bacteria.

Supertest evaluates performance of engineering students in Russia, the United States, India, China

The Supertest study assesses the academic performance of engineering students in four countries, revealing notable differences in critical thinking skills. Russian students excel in mathematics and physics at the start of their studies, while Chinese students perform better overall. However, Chinese students' critical thinking skills d...

Hotter, drier, CRISPR: editing for climate change

Scientists at the University of Queensland are using gene editing technologies to develop crops that can thrive in extreme and variable climate conditions. By integrating CRISPR-Cas9 genome editing into modern breeding programs, researchers aim to increase crop resilience and nutritional quality, ensuring global food security.

How 'great' was the great oxygenation event?

Researchers found evidence of oxygen-using enzymes in ancient bacteria and archaea, dating back 3 billion years before the Great Oxygenation Event. This suggests that life forms already utilized oxygen long before the main event, which allowed for the evolution of humans and other oxygen-breathing organisms.

Breast cancer screening recalls: simple MRI measurement could avoid 30% of biopsies

A research team from MedUni Vienna has confirmed a threshold value for a non-invasive imaging biomarker in breast cancer screening. This can be incorporated into short standard MRI scans to reduce biopsy rates by 30%. DWI, a special MRI technique, measures the motion of water molecules and can indicate whether a biopsy is necessary.

Education, interest in alternative medicine associated with believing misinformation

A study by the American Psychological Association found that individuals with lower education levels and those who have a positive attitude towards alternative medicine are more susceptible to believing misinformation on healthcare topics. The researchers also discovered that people who fell for misinformation on one topic were more li...

New study challenges 'established' mechanism about selectivity of cellular ion channels

A team of researchers from the University of Fukui and Kanazawa University have challenged the long-held assumption that potassium channels are highly selective for potassium ions. Their findings indicate that sodium ions can also pass through these channels, with a conductance one-eightieth that of potassium ions.
