1. New Super-Resolution Technique Allows for More Detailed Brain Imaging

13 Jun 2021

A new imaging technique has the potential to detect neurological disorders—such as Alzheimer’s disease—at their earliest stages, enabling physicians to diagnose and treat patients more quickly. Termed super-resolution, the imaging methodology combines position emission tomography (PET) with an external motion tracking device to create highly detailed images of the brain.


2. Touchless Technology Could Enable Early Detection and Treatment of Eye Diseases That Cause Blindness

A non-contact laser imaging system could help doctors diagnose and treat eye diseases that cause blindness much earlier than is now possible. The new technology is designed to detect telltale signs of major blinding diseases in retinal blood and tissue that typically go unseen until it is too late.


3. Obesity & Hypertension: Researchers Discover Novel Mechanisms

Researchers have succeeded for the first time in demonstrating the role of hypothalamic astrocytes in obesity-related hypertension. In addition, they showed that the hormone leptin is involved in the increase of blood vessels in the hypothalamus of obese mice, contributing to hypertension.


4. New Treatment Stops Progression of Alzheimer’s Disease in Monkey Brains

A new therapy prompts immune defense cells to swallow misshapen proteins, amyloid beta plaques, and tau tangles, whose buildup is known to kill nearby brain cells as part of Alzheimer’s disease, a new study shows.


5. Research Identifies Link Between Gut Microbes and Stroke

New findings show for the first time that the gut microbiome impacts stroke severity and functional impairment following stroke.  The study builds on more than a decade of research related to the gut microbiome’s role in cardiovascular health and disease, including the adverse effects of TMAO (trimethylamine N-oxide) – a byproduct produced when gut bacteria digest certain nutrients abundant in red meat and other animal products.


6. Graphene ‘Camera’ Captures Real-Time Electrical Activity of Beating Heart

Scientists have captured the real-time electrical activity of a beating heart, using a sheet of graphene to record an optical image — almost like a video camera — of the faint electric fields generated by the rhythmic firing of the heart’s muscle cells.

7. ‘Nanodecoy’ Therapy Binds and Neutralizes SARS-CoV-2 Virus

Nanodecoys made from human lung spheroid cells (LSCs) can bind to and neutralize SARS-CoV-2, promoting viral clearance and reducing lung injury in a macaque model of COVID-19. By mimicking the receptor that the virus binds to rather than targeting the virus itself, nanodecoy therapy could remain effective against emerging variants of the virus.

8. Childhood Exercise Could Maintain and Promote Cognitive Function in Later Life

A research group has illuminated the changes in the brain’s neural network and cortex structure that underlie the positive association between childhood exercise and the maintenance and promotion of cognitive function in later life. The researchers showed that people who are physically active during childhood (up to 12 years of age) have higher cognitive functions in later life.
