The venous system maintains the health of our brains by removing deoxygenated blood and other waste products, but its complexity and variability have made scientific study difficult. Now, a UC Berkeley-led team of researchers has developed an innovative MRI technique that may expand our understanding of this critical system.
In a study published in Nature Communications, the researchers demonstrate how their new imaging method, Displacement Spectrum (DiSpect) MRI, maps blood flows “in reverse” to reveal the source of blood in the brain’s veins. This approach could help answer long-standing questions about brain physiology as well as provide a safer, more efficient way to diagnose disease.
Like some current MRI methods, DiSpect uses the water in our blood as a tracing agent to map perfusion, or blood flow, in the brain. The water’s hydrogen atoms possess a quantum mechanical property called spin and can be magnetized when exposed to a magnetic field, like an MRI scanner. But what makes DiSpect unique is its ability to track the “memory” of these nuclear spins, allowing it to map blood flow back to its source.
Emotional responses to sensory experience are central to the human condition in health and disease. We hypothesized that principles governing the emergence of emotion from sensation might be discoverable through their conservation across the mammalian lineage. We therefore designed a cross-species neural activity screen, applicable to humans and mice, combining precise affective behavioral measurements, clinical medication administration, and brain-wide intracranial electrophysiology. This screen revealed conserved biphasic dynamics in which emotionally salient sensory signals are swiftly broadcast throughout the brain and followed by a characteristic persistent activity pattern. Medication-based interventions that selectively blocked persistent dynamics while preserving fast broadcast selectively inhibited emotional responses in humans and mice.
The importance of our gut microbiota to our health has become increasingly clear in recent years as more and more studies have been released.
New research links chronic loneliness to strokes, early death, and worse outcomes than poor diet or lack of exercise. Here’s how to fix it.
In this episode of The Moss Report, Ben Moss sits down with Dr. Ralph Moss to explore the real-world pros and cons of using artificial intelligence in cancer research and care.
From AI-generated health advice to PubMed citations that don’t exist, this honest conversation covers what AI tools are getting right—and where they can dangerously mislead.
Dr. Moss shares the results of his own AI test across five major platforms, exposing their strengths and surprising failures.
Whether you’re a cancer patient, caregiver, or simply curious about how AI is shaping the future of medicine, this episode is essential listening.

Analysis flags hundreds of studies that seem to follow a template, reporting correlations between complex health conditions and single variables based on publicly available data sets.
From brain fog to depression and long Covid — here’s why creatine is gaining attention beyond the gym.
Long working hours may alter the structure of the brain, particularly the areas associated with emotional regulation and executive function, such as working memory and problem solving, suggest the findings of preliminary research, published online in Occupational & Environmental Medicine.
Ultimately, overwork may induce neuroadaptive changes that might affect cognitive and emotional health, say the researchers.
Long working hours have been linked to heightened risks of cardiovascular disease, metabolic disorders, and mental health issues. And the International Labor Organization (ILO) estimates that overwork kills more than 800,000 people every year, note the researchers.
With wildfires increasing in frequency, severity, and size in the Western U.S., researchers are determined to better understand how smoke impacts air quality, public health, and even the weather.
As fires burn, they release enormous amounts of aerosols—the vaporized remains of burning trees and homes that enter the atmosphere and the air we breathe. Now, a new study dissects these aerosols and gases to pinpoint their potential effects on our health as well as the planet’s short and long-term weather.
The research, published in Environmental Science: Atmospheres, measured air quality in Reno, Nevada over a 19-month period between 2017 and 2020 to capture both smoky and clear days. During this timeframe, smoke from more than 106 wildfires impacted the city’s air. DRI scientists Siying Lu and Andrey Khlystov led the research, which found increases in both fine aerosols (known as PM 2.5 for the size of the particulate matter) and carbon monoxide during smoky days.
