Wearable Brain Scan Technology Expanded For Whole Head Imaging

Scientists from the University of Nottingham developed an initial prototype of a new generation of brain scanner in 2018 which is a lightweight device that can be worn on the head like a hat, and can scan the brain even whilst a patient moves. Their latest research[1] has now expanded this to a fully functional…

Alzheimer’s Research: Nilotinib Appears Safe And Affects Biomarkers

A small, phase II, randomized, double blinded, placebo-controlled study to evaluate the impact of low doses of nilotinib in Alzheimer’s disease finds that it is safe and well-tolerated. The researchers, from Georgetown University Medical Center, say the drug should be tested in a larger study to further determine its safety and efficacy as a potential…

The Fascinating History Of Clinical Trials

Clinical trials are under way around the world, including in Australia, testing COVID-19 vaccines and treatments. These clinical trials largely fall into two groups. With observational studies, researchers follow a group of people to see what happens to them. With experimental studies, people are assigned to treatments, then followed. These study designs have come about…

Identified: How Ketamine Targets Depression

The anaesthetic drug ketamine has been shown, in low doses, to have a rapid effect on difficult-to-treat depression. Researchers at Karolinska Institutet report that they have identified a key target for the drug: specific serotonin receptors in the brain. The findings give hope for new, effective antidepressants. “In this, the largest PET study of its…

Blood Plasma Analysis Could Spot Signs Of ALS

Analysis of blood plasma could help identify diagnostic and prognostic biomarkers for amyotrophic lateral sclerosis, according to new research. The work[1] sheds further light on a pathway involved in disease progression and appears to rule out an environmental neurotoxin as playing a role in ALS. “Early diagnosis is important, but we are in dire need…

Neuroscience Microscopy: Taking A Deep Look Into Animals

A joint venture of the University of Vienna and the Medical University of Vienna, and the TU Wien (Vienna) allows researchers to look deep into organs and nervous systems of animals, ranging from squids and worms to fish and salamanders. Analyses of individual cells in the context of whole organs or tissues is becoming increasingly…

The Biochemistry of Love

Although evidence exists for the healing power of love, only recently has science turned its attention to providing a physiological explanation for love. The study of love in this context offers insight into many important topics, including the biological basis of interpersonal relationships and why and how disruptions in social bonds have such pervasive consequences…

How We Make Decisions During A Pandemic

With many states and towns lifting strict stay-at-home orders, people are faced with a growing number of new decisions. Mundane logistical questions – Should I go get my hair cut? When can I picnic with friends? What should I wear to the hardware store? – during the Covid-19 pandemic carry implications for personal and public…
