Ultra-sensitive lead detector could significantly improve water quality monitoring

Sciencedaily.com 

Engineers have developed an ultra-sensitive sensor made with graphene that can detect extraordinarily low concentrations of lead ions in water. The device achieves a record limit of detection of lead down to the femtomolar range, which is one million times more sensitive than previous technologies.

World's largest childhood trauma study uncovers brain rewiring

Sciencedaily.com 

The world's largest brain study of childhood trauma has revealed how it affects development and rewires vital pathways. The study uncovered a disruption in neural networks involved in self-focus and problem-solving. This means under-18s who experienced abuse may struggle with emotions, empathy and understanding their bodies.

Direct view of tantalum oxidation that impedes qubit coherence

Sciencedaily.com 

Scientists have used a combination of scanning transmission electron microscopy (STEM) and computational modeling to get a closer look and deeper understanding of tantalum oxide. When this amorphous oxide layer forms on the surface of tantalum -- a superconductor that shows great promise for making the 'qubit' building blocks of a quantum computer -- it can impede the material's ability to retain quantum information. Learning how the oxide forms may offer clues as to why this happens -- and potentially... Читать дальше...

Lighting up Alzheimer's-related proteins to allow for earlier disease detection

Sciencedaily.com 

Many neurodegenerative diseases, including Alzheimer's and Parkinson's, are difficult to diagnose before symptoms begin to appear. However, disease-related biomarkers such as aggregated proteins called amyloids could provide important insight much earlier, if they can be readily detected. Researchers have developed one such method using an array of sensor molecules that can light up amyloids. The tool could help monitor disease progression or distinguish between different amyloid-related conditions.

Weight loss surgery most effective for long-term blood pressure control

Sciencedaily.com 

Bariatric surgery is more effective in controlling hypertension rates, or high blood pressure, in people with obesity and uncontrolled high blood pressure compared to blood pressure medication alone, according to a new study. People who underwent bariatric surgery had lower BMI and were on fewer medications after five years while maintaining normal blood pressure levels than those who only used antihypertensive medications.
