Blood Test to Track Gene Expression in the Brain Could Help Prevent Neurological Diseases

Addressing this challenge, scientists have now introduced a noninvasive method to track gene expression in the brain, potentially transforming research in brain development, cognitive function, and neurological disorders.

The team of scientists at Rice University (Houston, TX, USA) has developed a groundbreaking class of molecules named released markers of activity (RMAs).

Long COVID: Definitions, Diagnosis, and Developments

Many symptoms of post-viral conditions are nonspecific, and long COVID is no different.

The National Institutes of Health (NIH) Researching COVID to Enhance Recovery (RECOVER) study examined nearly 10,000 participants to identify 12 signature symptoms of the condition: postexertional malaise, fatigue, brain fog, dizziness, gastrointestinal symptoms, palpitations, altered sexual desire or capacity, altered or absent smell or taste, thirst, chronic cough, chest pain, and abnormal movements, such as tics or tremors.

Another study found seven distinct symptoms, adding hair loss, chest and joint pain, dyspnea, and obesity to the list.

Satellite offers a flood warning breakthrough

Scientists from the University of Glasgow say they have established a new method to measure water behaviour by analysing sensor data relayed from the orbit.

A team from the School of Geographical & Earth Sciences describes in Geophysical Research Letters how the method might boost or even replace current tools employed for environmental reporting.

With climate change contributing to more frequently unpredictable weather events, the technique could offer a more efficient and timely response, they say.

Standard practice for measuring river flow relies on stream gauges, that note discharge – the volume of water flowing past a particular point in a river second by. The method however can be both difficult and costly to implement and maintain, given that many sites are geographically remote.
