Medical Xpress / Coffee consumption linked to leaner body composition and sex-specific hormone patterns
Coffee is one of the world's most widely consumed beverages, and previous research has linked its consumption to a lower risk of conditions such as type 2 diabetes and cardiovascular disease. However, the biological mechanisms ...
Medical Xpress / Rb's unexpected activation of estrogen-responsive genes could explain breast cancer treatment resistance
Researchers at Peter Mac have discovered why breast cancer treatment stops working for some patients, uncovering the unexpected role of one of the body's most important cancer-fighting proteins. The study, published in Nature, ...
Medical Xpress / Astrocytes directly regulate brain circuits that consolidate memories during sleep, study reveals
Research has shown that a good night's sleep has many benefits, including memory consolidation. How sleep enables the brain to strengthen memories is still not completely understood, but a new study published in Neuron reveals ...
Medical Xpress / New brain map connects mice and primates to strengthen medical research
Most neuroscience research still runs on mice, even though much of what applies to mice does not hold up in humans. Marmosets have emerged as a bridge between species. However, comparing the brains of mice and marmosets runs ...
Medical Xpress / New spike map shows how SARS-CoV-2 variants dodge key antibodies
Antibodies are an important defense against SARS-CoV-2, but the virus continues to evolve ways to evade them. Now, researchers have mapped how antibodies target a key region of the virus's spike protein, how they neutralize ...
Medical Xpress / Cancer-specific c-Myc mapping reveals overlooked SLK protein as treatment target
Using a photochemically driven labeling technique, a Cornell-led research group has devised a strategy for capturing cancer-specific protein–protein interactions, which could one day lead to targeted therapies for prostate, ...
Medical Xpress / When phones become an escape: Nomophobia tied to heavier social media use during downtime
Smartphones have become an essential part of everyday life. The anxiety or discomfort experienced when people are unable to use their mobile phones or when their phones are not within reach is known as nomophobia in psychology.
Medical Xpress / Why brain imaging struggles to identify psychiatric disorder signatures
For decades, neuroscientists have been trying to determine whether different neuropsychiatric conditions are linked to specific variations in brain structure and neural connections. While past studies identified possible ...
Medical Xpress / Potential language-specific brain network identified
The language network in your brain can be seen, even if you aren't saying a word. For a study published in Nature Communications, researchers used data from more than 1,900 functional magnetic resonance imaging (fMRI) scans ...
Medical Xpress / First heart signaling atlas could help identify drugs that act directly on heart muscle
QIMR Berghofer researchers have created the most detailed map yet of the chemical signals that control heart function, opening new avenues for the diagnosis, treatment and prevention of heart disease.
Medical Xpress / New single-cell atlas reveals the plasticity of the human pancreas
An international research team coordinated by the Berlin Institute of Health at Charité (BIH) has created the most comprehensive single-cell atlas of the human pancreas to date. As part of a Human Cell Atlas project led by ...
Medical Xpress / Darier disease cells lose antioxidant defenses under stress, study finds
Northwestern Medicine scientists have uncovered a mechanism that may explain why people with Darier disease, a rare genetic skin disorder, often develop symptoms years after birth and experience painful flare-ups triggered ...
